History and Components of a Modern Mainframe Computer

Mainframe computers are critical for some of the largest corporations in the world. Each mainframe has more than one modern processor, RAM ranging from a few megabytes to multiple-score gigabytes, and disk space and other storage beyond anything on a microcomputer. A mainframe can control multiple tasks and serve thousands of users every second without downtime.

The chief difference between mainframes and other computing systems is the level of processing that takes place. Mainframes are also different in terms of data bandwidth, organization, reliability, and control. Big organizations-banking, healthcare, insurance, and telecom companies, etc.-use mainframes for processing critical commercial data.

In this article, we discuss the evolution of mainframe computers and their components.

History of mainframe computers

IBM developed a critical part of mainframe computing, the Automatic Sequenced Controlled Calculator (ASCC) for arithmetic operations, in 1944. From the late 1950s through the 1970s, several companies manufactured mainframes: IBM, Burroughs, RCA, NCR, General Electric, and Sperry Rand, for example. Since then, System / 390 by IBM is the only kind of mainframe in use. It evolved from IBM's System / 360 in 1960.

An Early mainframe occupied a huge space. New technologies have drastically reduced the size and cost of the hardware. A current-generation mainframe can fit in a small closet.

Components of a modern mainframe computer

Like a PC, a mainframe has many components for processing data: operating system, motherboard or main board, processor, controllers, storage devices, and channels.

• Motherboard: The motherboard of a mainframe computer consists of a printed circuit that allows CPU, RAM, and other hardware components to function together through a concept called "Bus architecture". The motherboard has device slots for input cards and cable interfaces for various external devices. Where PC motherboards use 32- or 64-bit buses, mainframes use 128-bit buses. General instructions regarding the internal architecture help the motherboard connect to the other devices and retrieve data using binary computation.

• Processor: A CPU acts as the central processing point in mainframe architecture and includes an Arithmetic Logic Unit (ALU) for performing arithmetic calculations. It also works as a controller for the bus architecture and handles traffic and data requests. The processing power of mainframes is much higher compared to PCs, so that they can handle huge amounts of data.

• Storage devices: Storage devices are for entering, retrieving, storing, and recording data. Many are external devices, such as hard drives, tape drives, and punch card readers, all connected to terminals of the mainframe and controlled by the CPU. Their capacity for data storage can be hundred or even thousands of times that of a PC.

• Communication controllers: Communication controllers allow remote computers to access a mainframe. With the help of networks, LAN or WAN, communication controllers establish connections with various devices, perform data transmission over communication channels, and keep track of users at terminals.

• Channels: The "channels" are the cables used to connect the CPU and the main storage to other parts of the system and make sure that data is moved in a systematic way without losing its integrity.

Modern mainframes have advanced features such as expanded service management capabilities, cross-platform integration facilities, etc. And so are suitable for critical data center operations. The cost of maintaining modern mainframes is much less compared to older models.

How Are Brains Different From Computers?

Ever wondered how brains are different from computers? This article shows how. Read on to find out.

Brains consist of cells called neurons and they connect with millions of other neurons and information gets transferred across connection gaps called synapses. Inside the cells data are processed which gives rise to an idea, concept or understanding.

Computers are built of hardware chips and the central processing unit (CPU) processes data after receiving them from the other chips. How it processes data conss of several steps but the main outline is that software programs are fed into the CPU and processed. They provide end result information depending on how the programs are furnished with data and what the query is that fed into the system. If some information is asked that is outside the scope of the software programs, the computer gets limited in functioning.

Brains, however, are limitless. From childhood until adulthood, the brain gets more and more developed and mature. It can process unknown data or abstract data as well and provide insights and knowledge.

The brain is more complex than the CPU and therefore, with neurons and synaptic connections, it is possible to process all kinds of information. It uses the five senses: touch, smell, hearing, taste and sight and takes in information and produces knowledge.

On the other hand, the CPU of computers takes in data from the typing of the keyboard and processes it, which is very limited. However, it is only human beings feeding data, writing software programs and making the computer like like a brain although not quite so.

The brain is still more intelligent than the CPU of computers and has yet to train the computer to have like the brain of a human being.

Yes, computers will be able to take over many tasks of human beings but without human beings, they are lifeless because humans have to give life to these computers, operate on them and have regular updating, monitoring and maintenance on them.

Just as a brain needs to rest and relax, computers will also need that from time to time but they can operate longer times than the average brain. While the brain sleeps, the computer can carry on with its duties of processing data and converting them to knowledge and information.

Summing up, although the CPU is sometimes called the brain of the computer, it is actually a misnomer because as I have outlined in this article, the brain is definitely different from the computer in varying ways and the brain has yet to teach the computer to Behave 100% like a brain.

What Is The Difference Between ERP And Enterprise System?

Enterprise system and Enterprise Resource Planning System terms are similar but there is difference between an enterprise system and an ERP system. An ES or enterprise system is a large scale system which includes packages like ERP and CRM. ERP is a subset of Enterprise System or it can be said that ES is a superset of ERP. It contains a variety of solutions. ES contains applications and packaged solutions which can be directly used in an enterprise. On the other hand ERP system is the automation of the business processes and the solutions are in the form of modules which are designed according to the client’s requirements.

The functions are customized according to the client’s business environment. Enterprise system does not include architecture of other solutions whereas an ERP implementation automates systems using technical aspects. ERP system includes architectures and databases and is client server architecture. The system is server based therefore the consultant needs to be aware of the technical aspect too.

Another difference between an ES and an ERP system is that the ERP is aimed at improving the functionalities of the organization whereas the ES helps to improve the overall maintenance and accuracy. It provides for better solutions and aids in decision making. ES is difficult to implement compared to Enterprise resource planning and even the timeframe needed for implementation maybe more. The overall impact is high but so are the risks involved. If the ES is not implemented in the right manner, it can cause business failure and if implemented properly it can increase the efficiency and profits of the business organization. It is normally required when there is a big drawback in the current procedures and methodologies in the organization and need to be corrected. The company going in for enterprise system needs to be careful while choosing the software and the vendors due to the risk of failure involved.

The difference between an enterprise system and an ERP system is that ERP is mostly used for medium scale companies to big companies and ES is restricted to the big companies. There are many complex functions involved in big companies which cannot be provided solutions for alone by ERP. The role of ERP is restricted when compared to enterprise system because it does not include customer relationship or vendor management.

These applications are needed when the business process is complex and on a big scale. Therefore bigger organizations need to go with ES instead of enterprise resource planning alone. ERP is also an important system to streamline the internal processes but it does not provide for taking care of the external processes. Enterprise system takes care of the end to end business process of organization since it involves other applications also like SCM and CRM. There is quite a lot of difference between an enterprise system and an ERP and it depends on the company whether it wants to go with an ES to streamline the entire process starting from supplying, production and customer or whether he wants to go with an ERP system to streamline the internal process.

How Useful is CAD Software to Engineers and Architects?

The emergence of advanced technology has made people today dependent on machines. Using computers and software, for example, is a very common illustration of this. Computer experts are coming up with more and more software to make more and more jobs easier.

A more specific illustration of this can be found in the modern approach towards engineering and architecture. These days, professionals in these fields use CAD computer software which is a program that allows them to create designs faster, easier and with more accurate measurements. Aside from the convenience that CAD software brings, it also helps put architects and engineers ahead of their competitors. CAD, which can render designs that are two-dimensional or three dimensional, stands for Computer Aided Design and has been in use since 1982.

So how does CAD computer software work? And what does it do exactly to help engineers and architects? The program is actually multifaceted in the sense that there are many ways it can help. To make CAD work will require, however, a careful study of its features and the many ways it can be used. It is rather a complex yet flexible and highly functional program.

This article will not be enough to discuss the various ways that CAD works but pinpointing its advantages could give some very good ideas. One great advantage of CAD computer software is its easy-to-use tools in the creation and alteration of designs. Obviously, this is so much better than the old fashioned way of using a pencil and eraser directly on paper. This method of designing is obviously so much easier and engineers and architects simply have more time to finish other tasks. In other words, high productivity is going to be the main end result of using CAD.

Before the design is actually printed on paper, CAD also allows both the design professional and the client to preview what has been finished so far. Any alterations can be made simply by manipulating the drawing through the use of the software. With CAD, it is so much easier to spot errors because the designs can be rendered exactly as they would be in reality. Hence, modifications can be done even before printing, thus, allowing one to save.

With the tough competition that everyone has to face these days, it is wise to take advantage of new technologies that can help put them ahead in the race. While traditional methods hold a significant part in the history of design, advanced tools such as CAD software should only be welcomed as man’s way of furthering development in a field of expertise that he himself has created long ago.

How Has Technology Changed Art?

We all are witnessing the changes being made in the art these days. Technology has the power to change anything. It is changing the traditional art into digital art.

Amazing digital art has taken place of traditional art. Digital art is exploring itself in many different ways that one can imagine. Different software is developed to increase the presence of digital art.

Photoshop Artists are one of the most common digital artists who give an amazing look to a picture with the help of imaging software and different applications.

These applications are developed with the help of technology. Anyone can be a digital artist having knowledge and proficiency in Photoshop.

Difference between traditional artists and digital artists is that traditional artists use paint and cement for their art and digital artists use imaging software and applications in their art. Some of the applications have the power to create 3D art work.

Technology has taken art into a new level of creativity. Let us talk about how technology has changed traditional art into digital art. We know that internet is ruling the world with its power. So, artists decided to present their art online with the help of internet. This is possible with use of technology.

You must have seen art galleries and attended painting exhibitions in your life. These doesn’t work well these days so artists find a way where they can get more attention and more praise for their work. Most of the artistic stuff is now seen online and is circulated to the art lovers.

There are some places where exhibitions are held and we do respect them. But presenting paintings, sculptures and art work online is in trend. Some of the artists are also showing their art on the basis of card swipe panel or coins.

How this work – when you enter coins or swipe card in the panel, the panel shows you some of the art work for a few minutes and then gets closed and if you want to see it again or explore more, further you need to swipe your card or add coins into it. This is how artists are using technology.

How digital artists are using technology for their art work

Digital artists already in touch with technology are aware of the systems that are in trend and use them to create their art work and sell them online.

Some of the professional digital artists are earning a lot of bucks by selling their art work. They can also design the ones that you want and are also ready to make any modifications you need.

They use different software to explore their skills and made it more impressive. They are using technologies that offer new ways to express their art work in a realistic way for much more time.

They are using different types of media and mix them to provide a more creative art work. Their 3D art work looks as real as it is present live in front of you.

Technology not only brings changes in education, medical field, industry and business but also brings a huge change in the art work and the artists as well.

Technology opens different paths for the artists to enter into for a good earning. They made their profession more powerful along with their art work.

In our busy lives we hardly get time to meet each other and our loved ones. How can it be possible to see exhibitions and galleries? So technology has brought this change in the art workers to show their skills and talent to people from anywhere in the world.

Technology is getting advanced and making more useful for the common man as well as artists. Technology has provided us with several things that we should be thankful. One of them is digital art work.

Examples Of Spyware And What They Are

Spyware is a general term used to describe software that performs certain behaviors such as advertising, collecting personal information, or changing the configuration of your computer, generally without appropriately obtaining your consent first.

Spyware is often associated with software that displays advertisements (called adware) or software that tracks personal or sensitive information.

That does not mean all software that provides ads or tracks your online activities is bad. For example, you might sign up for a free music service, but you “pay” for the service by agreeing to receive targeted ads. If you understand the terms and agree to them, you may have decided that it is a fair tradeoff. You might also agree to let the company track your online activities to determine which ads to show you.

Other kinds of Spyware make changes to your computer that can be annoying and can cause your computer slow down or crash.

These programs can change your Web browsers home page or search page, or add additional components to your browser you don’t need or want. These programs also make it very difficult for you to change your settings back to the way you originally had them.

The key in all cases is whether or not you (or someone who uses your computer) understand what the software will do and have agreed to install the software on your computer.

There are a number of ways Spyware or other unwanted software can get on your computer. A common trick is to covertly install the software during the installation of other software you want such as a music or video file sharing program.

Any software that covertly gathers user information through the user’s Internet connection without his or her knowledge, usually for advertising purposes. Spyware applications are typically bundled as a hidden component of freeware or shareware programs that can be downloaded from the Internet; however, it should be noted that the majority of shareware and freeware applications do not come with SpyWare. Once installed, the Spyware monitors user activity on the Internet and transmits that information in the background to someone else. Spyware can also gather information about e-mail addresses and even passwords and credit card numbers

Aside from the questions of ethics and privacy, SpyWare steals from the user by using the computer’s memory resources and also by eating bandwidth as it sends information back to the spy ware’s home base via the user’s Internet connection. Because SpyWare is using memory and system resources, the applications running in the background can lead to system crashes or general system instability.

Because SpyWare exists as independent executable programs, they have the ability to monitor keystrokes, scan files on the hard drive, snoop other applications, such as chat programs or word processors, install other SpyWare programs, read cookies, change the default home page on the Web browser, consistently relaying this information back to the SpyWare author who will either use it for advertising/marketing purposes or sell the information to another party.

Licensing agreements that accompany software downloads sometimes warn the user that a SpyWare program will be installed along with the requested software, but the licensing agreements may not always be read completely because the notice of a SpyWare installation is often couched in obtuse, hard-to-read legal disclaimers.

Examples of SpyWare

These common SpyWare programs illustrate the diversity of behaviors found in these attacks. Note that as with computer viruses, researchers give names to SpyWare programs which may not be used by their creators. Programs may be grouped into “families” based not on shared program code, but on common behaviors, or by “following the money” of apparent financial or business connections. For instance, a number of the SpyWare programs distributed by Claria are collectively known as “Gator”. Likewise, programs which are frequently installed together may be described as parts of the same SpyWare package, even if they function separately.

o CoolWebSearch, a group of programs, takes advantage of Internet Explorer vulnerabilities. The package directs traffic to advertisements on Web sites including coolwebsearch.com. It displays pop-up ads, rewrites search engine results, and alters the infected computer’s hosts file to direct DNS lookups to these sites.

o Internet Optimizer, also known as DyFuCa, redirects Internet Explorer error pages to advertising. When users follow a broken link or enter an erroneous URL, they see a page of advertisements. However, because password-protected Web sites (HTTP Basic authentication) use the same mechanism as HTTP errors, Internet Optimizer makes it impossible for the user to access password-protected sites.

o Zango (formerly 180 Solutions) transmits detailed information to advertisers about the Web sites which users visit. It also alters HTTP requests for affiliate advertisements linked from a Web site, so that the advertisements make unearned profit for the 180 Solutions Company. It opens pop-up ads that cover over the Web sites of competing companies.

o HuntBar, aka WinTools or Adware,WebSearch was installed by an ActiveX drive-by download at affiliate Web sites, or by advertisements displayed by other SpyWare programs-an example of how SpyWare can install more SpyWare. These programs add toolbars to IE, track aggregate browsing behavior, redirect affiliate references, and display advertisements.

oZlob Trojan or just Zlob, Downloads itself to your computer via ActiveX codec and reports information back to Control Server. Some information can be as your search history, the Websites you visited, and even Key Strokes.

How to Change the MPI Node Address For a Siemens S7-300 PLC

I have seven Siemens S7-300 PLCs connected together using the MPI (Multi Point Interface) interface. The Siemens MPI protocol is used by Siemens PLCs to communicate with external devices. I want to rename each of the seven PLCs. Here are the steps to accomplish that task.

First, connect your MPI cable to the first PLC. I will be connecting my laptop to each PLC individually. Power up the PLC and open Simatic Manager. The "New Project" Wizard window will open. Just click Cancel to close the window. Now click the Accessible Nodes icon on the toolbar. A window will open showing the identification of the PLC you are connected to. My window is showing MPI = 2 (directly). Make a note of this address and close the window.

Next we need to download a hardware configuration to the PLC. This is where we will rename the PLC node address. There are probably a couple of different ways to do this – following is how I accomplish this. All seven of my PLCs are the same model; Therefore, I am using the same hardware configuration. For the obvious reasons, I want to give each a different MPI node address. I have a project file that contains all seven of my PLC programs and one hardware configuration file. I open the one hardware configuration file, and then double click Hardware in the right hand window. This will open the HW Configuration window. In this window you should see your PLC with its MPI address given.

Remember when we clicked the Accessible Nodes icon and saw MPI = 2 (directly)? My Hardware Configuration Window is showing a MPI address of 7. Place your mouse cursor on the 7 and double click. Your CPU Properties window will open. It should open to the General tab. Look down and you will see Interface Type MPI with an address of 7. Click Properties and the MPI interface Properties window will open. Using the pull down menu, choose your MPI node address and make sure the MPI (1) 187.5kbps is highlighted and click OK. You are now back on the CPU Properties window where you will see your address has changed. Click OK and you will go back to the Hard Ware window where you can verify your MPI node address has changed.

You will now click the Save and Compile icon and then click the download icon. The Select Target Module window will open. Click OK and the Select Node Address window will open. Here you will see the MPI node address you assigned earlier. You will need to click the View button right below this. You will see the current node address appear, this should be the same as what you saw earlier when you clicked the Accessible Nodes icon. Simply click on this number and you will see it appear in the MPI address slot under the Enter connection to target station. Click OK and the Download to Module window will open. Click OK and the Stop Target Modules window will open. Click OK and the "Do you want to start the module?" Window will open. Click Yes.

Now go back to the SIMATIC Manager window and click the accessible nodes icon. You will see your new MPI node address. You can see this same article with pictures at http://www.morerobototics.com .

Introduction to Silk Test Architecture

Normal use of an application consists of a person manipulating a keyboard and mouse to initiate application operations. The person is said to be interacting with the GUI (Graphical User Interface). During Silk Test testing, Silk Test interacts with the GUI to submit operations to the application automatically.

Thus Silk Test can simulate the actions of a person who is exercising all the capabilities of an application and verifying the results of each operation. The simulated user (Silk test) is said to be driving the application. The application under test reacts to the simulated user exactly as it would react to a human rest. Silk Test consists of two distinct software components that execute in separate processes:

The Silk Test host software

The 4Test Agent software

Silk Test host software

The Silk Test host software is the program you use to develop, edit, compile, run and debug your 4Test scripts and test plans. This manual refers to the system that runs this program as the host machine or the Silk Test machine.

The Agent

The 4Test Agent is the software process that translates the commands in your 4Test scripts into GUI-specific commands. In order words, it is the Agent that actually drives and monitors the application you are testing. One Agent can run locally on the host machine. In a networked environment, any number of Agents can run on remote machines. This manual refers to the systems that run remote Agents as target machines. This manual refers to the systems that run remote Agents as target machines. In a client/server environment, Silk Test drives the client application by means of an Agent process running on each application’s machine. The application then drives the server just as it always does. Silk Test is also capable of driving the GUI belonging to a server or of directly driving a server database by running scripts that submit SQL statements to the database. These methods o directly manipulating the server application are intended to support testing in which the client application drives the server.

Why Architectural Drafting Is Common in Architectural Design

For architectural design projects, while there is the emphasis on using 3D models and architectural BIM modeling, the time-tested practice of using architectural drafting and 2D technical drawings is still commonplace in the AEC industry. Architectural drafting has evolved from the drawing board to computer-aided design and drafting (CAD) software programs. Drafting practices help to provide architectural construction drawings that include the technical details of architectural, structural and electrical elements required for the construction of a building. To understand the stage at which architectural drafting takes place, the workflow of a building design lifecycle must be considered.

The basic workflow of an architectural design project starts with the architect creating a conceptual plan which is usually modelled into architectural 3D models and rendered as photorealistic images for marketing and presentation to clients and customers.

Once the conceptual design is approved by the client, the design is then progressed into more detail and shared with other parties such as structural and MEP engineers. The way in which the design is progressed for the ‘design development’ phase by an architect lends itself to two options, either to develop a 3D model with more detail and then create subsequent sheets and details using a 3D tool such as Revit or AutoCAD, or as is still commonplace, to develop the concept design in 2D using more traditional methods. From the conceptual plans provided by architects and engineers, a drafter can convert these designs using CAD software programs to create technical drawings.

Architectural drafting is the process of creating technical drawings which include the floor plan, sections, elevations, detailed drawings and other documents in a construction drawing set (CD Set), which are typically required for the construction of a building.

The difference between Architectural Drafting and Modelling

Architectural drafting refers to creating 2D technical drawings and architectural construction drawings which are mainly used by contractors and consultants on site. Architectural 3D modelling refers to creating 3D models and renders of photorealistic images which are mainly used to present the architectural design for marketing purposes and then progressed from there to create the 2D technical drawings, in effect feeling like an extra stage (the 3D modelling element). The main software used for drafting, to create 2D technical drawings is AutoCAD while modellers use Revit and ArchiCAD to create 3D models and rendered images. Architectural draftsmen need to have basic 2D and 3D software knowledge such as AutoCAD and knowledge of technical codes and drafting guidelines specified by organisations such as American National Standards Institute (ANSI), American Society of Mechanical Engineers (ASME), American Design Drafting Association (ADDA), Public Works Government Services Canada (PWGSC), National Institute of Building Sciences (NIBS), BSI British Standards Institute and Standards Australia Code AS1100. Architectural modellers need to have a deeper understanding of architectural, building and construction concepts and experience with 3D software programs such as Revit and ArchiCAD.

Why Architectural Drafting is still Common in Architectural Design Practices

Architectural 3D models are preferred by architects and designers because they provide a 3D perspective of the conceptual plan of the building; it makes management of project data easier and allows for design changes on the go. However, construction companies that require technical specifications of the architectural project prefer 2D technical drawings and architectural construction drawings because they provide accurate details required for construction, most of the resources involved in construction understand 2D drawings, there are no issues with compatibility of software as compared to when using 3D models and it is a suitable solution to meet the budgetary requirements of a construction project. Some of the reasons why architectural drafting is preferable by several construction companies include:

• Suitable as per construction requirements – In some building projects, 2D technical drawings or architectural CAD drawings are sufficient to complete construction, where additional information that 3D models provide is not required. A construction drawing set (CD set) includes all the floor plans, elevations, sections and detailed drawings required for construction. Technical codes, symbols and other additional information such as the type of material are provided in technical drawings. Therefore, construction companies find 2D technical drawings sufficient to successfully complete construction.

• Availability of technical resources – Not all companies have technical resources to deliver 3D models. While drafting teams are qualified to work on AutoCAD to deliver 2D technical drawings, they may not be qualified to work on Revit to deliver 3D models. In the construction industry, the availability of drafting teams who can provide 2D technical drawings is ample compared to companies that provide 3D modelling services.

• Availability of software – The adoption of new software and practices is gradual and slow in the construction industry. The software used in building projects varies from country to country. Some countries use ArchiCAD and AutoCAD Architecture instead of Revit, therefore leading to the incompatibility of project data. 2D technical drawings in AutoCAD are widely used and compatible making it a preferred option to Revit 3D models.

• Suitable as per cost and budgetary requirements – In most cases, construction companies do not find the need to invest more in 3D models, when drafting solutions provide detailed technical drawings which are sufficient and relevant enough for construction. There is also the added investment in resources that are competent enough to understand and implement architectural 3d models on-site.

While architectural 3D modelling and BIM modelling provide design-related information typically required for architects and designers in the design stage of the building project lifecycle, architectural drafting provides technical drawings that are not just about aesthetics but about high-performance detailing of construction elements. Architectural CAD drawings specifically communicate the design intent and help in the construction of buildings which companies find relevantly sufficient over 3D models. Even as construction companies will need to eventually evolve to combining the use of 2D technical drawings and architectural 3D models until then, the time-tested practice of using architectural drafting and drawing solutions in construction is here to stay.
