The 4 Elements That Makes Up A Personal Computer System

There are 4 elements that make up a personal computer system: the user, software, hardware and the electricity all working together for the whole system. Each of these elements is essential to the system itself.

The user is the person's who perform the task using the computer system. The nature of the task depends upon the application program or software that is needed to perform the task. The software that the user used requires certain hardware components to function properly.

The hardwares of the personal computer system are made up of its equipment that are usually connected (the computer, monitor, printer and so on). It is defined as hardwares because you can physically touch these components. The programs are called softwares since their function can only be used when the computer is turn ON. Software is a set of coded instructions that the computer uses in order to carry out the user's tasks.

The user can only use the computer when it is turned ON. Without any electrical power to run through the personal computer system, it will not function. The ability of the personal computer system to control its components is through a series of on / off signals.

Here is how it works, when a user tries to type a document or a letter using his / her personal computer. The first thing the user do is to turn ON the power for the computer. Choosing a Word Processor software in order to write the document. The user uses the hardware such as the keyboard to write the content of the document; The typed document is then displayed onto the monitor screen. After the user finished writing his / her document. The user will use the software to instruct the printer to print the document. The software works together with the hardware components (the keyboard, monitor and printer) to accomplish the task that the user requested.

All of the four elements: the electrical power, hardware, software and the user work together to make up a personal computer system.

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.

Corel DRAW – Best Desktop Publishing Software

Corel DRAW is a supreme supplier of graphics software, including the popular Corel DRAW program. Corel DRAW has tools that allow the user to both create and edit images. The type of desktop publishing tools that you use will depend on the type of project. For more information and assistance, use the Corel website.

Corel DRAW is the best Desktop publishing software that empowers users to create illustrations containing graphics, text and photographs. Corel has an extensive range of tools which enable the user to edit any shape or character with ease and precision, fit text to curves and create custom color separations. It is developed and marketed by Corporation of Ottawa. This tool can open files: Adobe PageMaker, Microsoft Publisher and Word, and other programs can print documents to Adobe PDF using the Writer printer driver, which such software can then open and edit every aspect of the original layout and design.

Several innovations to vector-based illustration originated with Corel: a node-edit tool that operates differently on different objects, fit text-to-path, stroke-before-fill, quick fill/stroke color selection palettes, perspective projections, mesh fills and complex gradient fills.

One of this software’s many strengths is the huge range of over 1,000 fonts that it comes with, provided in both TrueType and Postscript Type 1 format. Corel differentiates itself from its opponent in a number of ways: The first is its positioning as a graphics suite, rather than just a vector graphics program. A full range of editing tools allow the user to adjust contrast, color balance, change the format from RGB to CMYK, add special effects such as vignettes and special borders to bitmaps. Bitmaps can also be edited more extensively using Corel PhotoPaint, opening the bitmap directly from Corel and returning to the program after saving. It also allows a laser to cut out any drawings.

Expert believed it was the first of the Windows-based drawing programs and has built on this early start to become far-and-away the dominant drawing package on the PC. Its biggest strength – and its biggest potential limitation – is its all-encompassing approach. In the past this has led to accusations of unfocused bloating, but with version 7.0 Corel has addressed the criticisms with a far tighter and better rationalized program. Even so, there’s a huge range of functionality to cover.

Corel DRAW Download was originally developed for Microsoft Windows and currently runs on Windows XP, Windows Vista, and Windows 7. The current version, X5, was released on 23 February 2010.

How To Select The Best Credit Repair Software

Credit repair software tools are available to assist both credit repair agencies and/or individual consumers with credit repair. Ideally, such repair software is user-friendly and allows the user to point and click to a series of questions, and subsequent options, to engage in the process of credit repair by challenging credit reports from the major credit bureaus.

There are many software companies to choose from. Some claim to be the “best” while others claim to have the “absolute best credit repair software on the planet.” They all provide a unique service with even more unique and distinct features. The issue that you need to consider most when selecting credit repair software is which feature set will benefit you the most. So let’s take a look at steps that will help you select the proper software package for you.

1. Try to find a product with good technical support. A proper credit repair software program behaves like other expert software. This means 24/7 technical assistance, recurring software updates, sufficient help/manual documentation, etc.

2. Your credit repair software must adhere to your personal needs. A lot of these products have numerous add-ons, bonuses and other things which you would be paying for, but may not need. For example, some vendors cater to credit professionals, so they have functionalities on client management, etc, which you don’t need as a home user. On the other hand, you might need financial tips or the automatic reminder system.

3. Keep in mind, that you may have to write letters and that you are a unique customer with a unique address, account number, social security number, and story behind your dispute, which will have to be inside the letter. This single activity will take you many hours to complete. Try to find a software that already has pre-loaded dispute letters. Then once the software has automatically extracted those disputes from the above mentioned credit report providers, this software will in turn suggest the appropriate dispute letter automatically within just a few seconds. Just imagine the hours, and amount of money you can save by just this feature alone. Most people have to hire or outsource this kind of work because their software does not do it automatically. So not only will you save time but you will also save money by not having to outsource the work.

4. Rank available packages through analyzing pros/cons/cost. Once you have a short list of possible software packages, try to rank them by analyzing the pros and cons of each, as well as comparing the cost to your budget.

5. See if there is a trial period for the software that you select. Now that you have selected which package you feel would be the best fit for you, make sure that there is a money back guarantee so that you can return it if you are not satisfied with the performance.

The more you work on your credit repair, the more that it will demand of your time. This is why it is extremely important to choose the best credit repair software available to help you automate the process as much as possible. Choosing the right software package for your needs can save you lots of time. Working with automated software can be compared to driving a car to a distant destination, versus walking there. One way will be significantly faster than the other. Repairing your credit will be much more difficult if you are not using an organized system.

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.

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.
