* Major Components of a Computer System*

# Hardware
Computer hardware is the physical part of a computer, including the digital circuitry, as distinguished from the computer software that executes within the hardware. The hardware of a computer is infrequently changed, in comparison with software and data, which are "soft" in the sense that they are readily created, modified or erased on the computer. Firmware is a special type of software that rarely, if ever, needs to be changed and so is stored on hardware devices such as read-only memory (ROM) where it is not readily changed (and is, therefore, "firm" rather than just "soft").

# Software
Computer software, consisting of programs, enables a computer to perform specific tasks, as opposed to its physical components (hardware) which can only do the tasks they are mechanically designed for. The term includes application software such as word processors which perform productive tasks for users, system software such as operating systems, which interface with hardware to run the necessary services for user-interfaces and applications, and middleware which controls and co-ordinates distributed systems.

# Peopleware
Peopleware is a popular book about project management. The first chapter of the book claims, "The major problems of our work are not so much technological as sociological in nature." The book approaches sociological or 'political' problems such as team 'jelling', quiet in the work environment, and the high cost of turnover. Peopleware - Productive Projects and Teams (ISBN 0-932633-43-9) is a popular 1987 book, written by software consultants Tom DeMarco and Timothy Lister, on the inside world of software developing teams, in a manner such as to highlight the real-world conflicting natures between individual work perspective and corporate ideology. Topics include team jelling, group chemistry, corporate entropy, flow time, "teamicide" and workspace theory (for optimization).

Different Parts of Computer System

* Hardware
Your computer's hardware is comprised of the devices that are part of your computer system- like the monitor, the speakers, and the motherboard.


Motherboard
The motherboard is one of the most important parts of your computer system! It is a complex array of wires, cables, and transistors. The most vital parts of your computer are located on your computer's motherboard.


Storage Devices Your computer needs to have a place to store all of the data and information it is given. Your computer won't have enough space in its random-access memory for all of this information. That is why there are additional storage devices.


Input/Output Devices
To let you, as the user, communicate with your computer, there are special input/output devices. Input devices let you input data into your computer, while output devices take your computer's computations and send them to you.



Audio Devices
There are a few special hardware devices that are specifically designed to work with sound. These devices can take sound waves and manipulate them in many ways.


Modems

One of the major reasons why people use computers is to access the Internet. Modems let you connect your computer with the millions of other computers in the Internet.



Connecting Cables
With so many different devices that can be connected to your computer, there'd have to be connecting cables. These cables connect devices like your printer or scanner to the computer system.


* Software
Software is the term that describes the instructions given to the computer so that it will know what tasks and operations to carry out! There is no real tangible form for software, like there is for a computer's hardware.


System Software
System software controls the computer's functions, as well as important peripherals like printers, monitors, and certain storage devices.


Operating System
The most important type of system software is the operating system. The operating system acts as an overseer over the whole computer system. Some of its major tasks are to control and organize the various devices that make up the hardware of a computer system and to support application software. Application software is the second major type of software, and will be talked about later on in this section.


Programming Languages
The second type of system software comprises of the many different programming languages found throughout the computer world. Programming languages are specialized languages that computers can understand.


Application Software
Application software is the software that controls the tasks you can use your computer to carry out. It includes any kind of program that can be used to carry out the instructions that you give the computer.


Word Processor
This are software programs that can be used for writing and typing up documents. Most of you have heard of Microsoft Word. Well, Microsoft Word is a good example of a word processor.


Spreadsheets
Computers are used frequently used to perform computations and operations. Spreadsheet programs are commonly used for budgeting, forecasting, and financial analyzing. They are most often used for financial-related tasks.


Computer Games
Computers games have provided millions of people around the world with entertainment for decades. Almost everybody has played, or at least heard of, computer games. There are simple game, like Solitaire, Tetris, and Minesweeper; there are more advanced and complex games, like Doom, Sim City, and Myst.


Video Software
There are certain programs that can be used to play back videos, such as Real Player and QuickTime. These programs let you view short video clips, movie trailers, and all sorts of other cool movies.


Music Software
If you like downloading music from the Internet, and then listening to them! Well, special software is used for this task. This software can be used to first download the music.
