by Cyberslayer

A computer is a general purpose machine capable of making complex calculations at extremely high speeds. Nowadays it seems that almost every device has a computer in it.

A computer is a combination of hardware and software. It has several components and they include the monitor, the CPU chassis, the mouse and the keyboard.

Components of a computer

Computer Monitor
The monitor is a device used by the computer to display texts and images. A few years ago almost every computer monitor used a Cathode Ray Tube. But these days, flat panel systems are getting more and more popular.

Keyboard
Keyboard is an input device used to input data into the computer. There are many different keyboard designs.

The Mouse
The mouse is another input device used to ‘point and click’. In the days of the DOS operating system, it was possible to operate a computer without mouse. But the advent of Graphical User Interface has made mouse a very important input device.

The CPU Chassis
The CPU chassis or the CPU case houses the hard disk and other hardware components like disk drives, motherboard etc.

Hardware
A computer’s hardware components are the parts you can see and touch. The smallest hardware component in a computer is a chip. A computer chip is composed of layers of wires and semi-conductors. The semi-conductors in a chip are configured to represent either a 0 or a 1 when electricity passes through them. The hardware components of a computer include Motherboard, Basic Input Output System (BIOS), Central Processing Unit (CPU), Memory (RAM), Disk Drives, Sound Processor, Video Processor, Floppy Disks, Hard Drives, CD-ROMs, DVD-ROMs and Adapter Cards.

Computer Software
Software is a set of instructions telling the computer how to process, store and retrieve data.

Software is basically of two kinds: Operating Systems and Applications.

Operating Systems
An Operating System is a kind of software used to run the computer. It provides us with an interface with which we can issue commands to the computer system. There are several different kinds of operating systems. Examples are: Windows, Linux, Unix and DOS. The Windows operating system built by Microsoft is the most popular Operating System used today. The MacIntosh computers use the MacOS and OS X operating systems built by Apple Computers.

Applications
An application is a set of software that is first installed on the computer and then executed by the computer’s processor. Applications allow users to interact with the computer so that they can create or process data or perform a specific task. Examples of applications are text editors, word processors, spread sheets, web browsers and email clients.

A text editor is an application that allows the user to create text files. A word processor is an advanced text editor. Spreadsheets allow users to create tables and columns of numbers and figures. With a spreadsheet you can perform calculations on numbers. An e-mail client is an application that can connect to an e-mail server to receive or send mail. Most e-mail clients available today are very sophisticated applications containing features like spelling checkers. A web browser is an application that allows you to access information available on the internet. Examples are: Mozilla Fire fox, Microsoft Internet Explorer, Safari and Opera.

by jon_a_ross

A Computer constitutes of different parts or components, which are collectively known as PC hardware. The main hardware PC units include display screen monitor, CPU, hard disk, mouse, CD drive, keyboard, etc. We can also buy a computer from a company or can also purchase an assembled model through an expert computer software person. If any part of the computer gets corrupted, you can also purchase separate components from any offline or online computer dealers.

The computer hardware parts also do include items such as sound cards, scanners, even digital cameras internet modems, etc. Every computer has its own individual configuration like model details, RAM memory, CPU etc which might vary from other computers.

Now let’s have a look at the most important hardware parts:

* CPU – CPU or Central Processing Unit is also known as the brain of the computer. It works as a processor, and processes all our commands and instructions. Intel processors are the most widely used processors in the world and are used by most of the computer manufacturing companies.

* Mouse - This is an essential hardware for desktop models as it is used for navigational purpose, to click on varied options, also for selecting different objects and to access necessary information present on the computer screen.

* Hard Disk – Hard Disk is used for the storage of data. A major part in the performance of any computer essentially depends on its hard disk.

The higher the rotational speed of hard disk the fast and high speed performance will be the by that particular computer.

* RAM - Ram is also known as Random Access Memory, which is used in storing temporary information in the CPU. As soon as we switch off the computer, these temporary info files are erased from RAM. The optimal performance of the computer highly depends on the size of its RAM.

* Keyboard - Keyboard is one of the most vital parts in computer hardware. The keyboard is used to enter specific instructions or commands by punching of numbers, alphabets, or signs. There are many function keys as well such as Alter, Control, delete, Page up, F keys, Page down, etc in the keyboard. There are a total of 101 keys in a standard keyboard however these days we can find keyboards of more or less keys as well, a keyboard is designed in such a way so as to make typing easier and faster.

DDR SDRAM Computer Hardware Guide

5873311023 c6d5ccf861 m DDR SDRAM Computer Hardware Guide
by Cyberslayer

DDR SDRAM stands for double data rate synchronous dynamic random access memory. It is a type of memory that is used in computer to help it accomplish tasks in twice the amount of speed as the old regular SDRAM chips of yesteryear.

Most DDR SDRAM chips have model numbers that match their speed. For example a PC-1600 chip transfers data at 1600 MB/s. A PC-3200 chip would then transfer data at 3200 MB/s which is the top speed of DDR memory.

These newer chips can hold up to 1 Gigabyte of RAM on one chip. Most motherboards have room for 2 or 3 RAM chips which means that you could have up to 3 Gigabytes of SDRAM in your computer which would really help with overall speed.

SDRAM is mainly used for the temporary processes and commands a computer goes through. We don’t realize how much a computer temporarily stores, so let us help give you an idea. For example, say you open up your e-mail. The computer first loads internet explorer, than opens of the web page, and sits there temporarily while you write your email until it send it. While it’s “waiting” it has pushed all those previous processes to it’s RAM to remember so that when it is ready to send it can just quickly pull that back up out of the ram and send the e-mail. From this example you can see how bogged down a computer can get when a person is playing a game while reading their e-mail and using Photoshop to edit pictures.

Greg writes articles about DDR SDRAM and for DDR ii sdram.

How to Analyze Computer Hardware

4351971947 6ff2c4319d m How to Analyze Computer Hardware
by Ice Foxx

Analyzing computer problems is a process which has become robotic in the Windows operating system. Device Manager, a native tool catalogs all of your computer’s hardware as well as the software, known as a driver which runs each of those devices. The Device Manager could also scrutinize the consistence of both the hardware and the software, allowing it to mechanically recognize problems. Once recognized, the Device Manager could also help you fix them as well.

IT professionals could look at the computer hardware and determine if it would fit with the objectives of a task or job. They must determine whether the computer hardware would be able to complete the job as a task couldn’t be completed without the right hardware and software.

While you discuss about the computer hardware analysis it’s also vital that you mention the fact that even the software of the computer relies on it in order to be installed within the computer system. Moreover, it’s also important that hardware analysis must also include vital elements connected to the hardware components and also the connections being established between these components so that you better understand the way in which they operate as a system.

In addition, any computer hardware analysis should also include vital examples of problems which could be encountered by the users while working with their computers and the way in which they could overcome them. Keyboard is one of the vital components of a computer hardware analysis which needs to be included. This is for the reason that it represents an input type of device whose designs look very similar to the one presented by the typewriters.

Power supply is another important component of the hardware analysis.

This computer hardware component is considered very significant in influencing the performance of the computer because it deals with supplying the essential power to the computer, without which it wouldn’t be possible for the computer to function.

Thus, to aid a user in making improvements in a computer system it would be constructive to conduct an analysis of different hardware components as the system performs a task of interest.

Basic Part of Computer Hardware

5873922458 613d6ee7b4 m Basic Part of Computer Hardware
by Cyberslayer

If you are using a desktop computer, you may already know that there isn’t any single part known as a “computer”. A computer is a system of several parts working together. The physical parts which you could see and touch are jointly known as hardware. There are some computer hardware parts which collectively form a computer.

Computer Hardware Parts:

System Unit

The system unit is the heart of a computer system. Generally, it’s a rectangular box placed on or beneath your desk. There are several electronic components which process information inside this box. The most vital of these components is the central processing unit (CPU), or microprocessor, which acts as the brain of your computer. Another component is the RAM or the random access memory which temporarily stores data that the CPU uses while the computer is on. When the computer is turned off, the information stored in RAM gets erased.

Hard Disk Drive

Your computer’s hard disk drive stores data on a hard disk, a firm plate or stack of plates with a magnetic surface.  The hard disks normally serve as your computer’s primary means of storage, holding almost all of your programs and files as it can hold enormous amounts of information. The hard disk is usually located inside the system unit.

DVD and CD Drives

Almost all computers today come equipped with a DVD or CD drive, generally located on the front of the system unit.

CD drives use lasers to read or retrieve data from a CD and several CD drives could also write or record data onto CDs. DVD drives could do everything that CD drives can plus they can also read DVDs. If you have a DVD drive, you could watch movies on your computer. Several DVD drives could record data onto blank DVDs.

Floppy Disk Drive

Floppy disk drives store information on floppy disks, also known as floppies or diskettes. Floppy disks compared to CDs and DVDs can store only a small amount of data. They also recover information more slowly and are more prone to damage. For these reasons, floppy disk drives are less admired than they used to be, though some computers still include them.
