Answer 2

Ok lets imagine u work at a office.

Now You are the CPU(the chip or central processing unit) The cpu carries out and outlooks the functions of your computer.

The harddirve is like a filing cabinet. it stores ur files and imgaes music videos whatever u have on ur computer.

Your RAM is very important. Its like your desk space on top. the more space you have the more files u can open up and put on ur desk. when u run out of ram ur computer automaticaly starts to use ur harddrive as ram which will drasticly slow ur computer down. it would be like getting up and going back and forth to ur filing cabinet and desk to get files instead of leaving them on ur desk.

Your cd drives and floppy dirves are used to transfer data around or play movies and music.

Your power box sends power to your computer. As the name says it all.

Your modem or LAN(Local area network) Is for internet
If u have dial-up ur using a 56k modem.
If ur using DSL cable or wireless then ur on a lan connection.

And your video card. This card can cost more than any part in ur computer or the computer it self. It is what send the picture to the monitor. the resolution, color, image quality, proformace, clearness, brightness and effects depend on this card, so investing in a good card is a good idea, u demand high quality pictures or play online.


Now all this put together make ur computer work.

Most people think that the faster the chip the faster the computer.
NO.If u put car in 1st gear and floor it ur gonna blow up ur engine and destory ur car.
Your chip will only run at its peak when u have enough ram( 512 is good 1 gb is best.) space, internet connection and protection agian ad-aware and viruses.

And thats about it.

How Computer works:-

When you mention the word "technology," most people think about computers. Virtually every facet of our lives has some computerized component. The appliances in our homes have microprocessors built into them, as do our televisions. Even our cars have a computer. But the computer that everyone thinks of first is typically the personal computer, or PC.
A PC is a general purpose tool built around a microprocessor. It has lots of different parts -- memory, a hard disk, a modem, etc. -- that work together. "General purpose" means that you can do many different things with a PC. You can use it to type documents, send e-mail, browse the Web and play games.

In this article, we will talk about PCs in the general sense and all the different parts that go into them. You will learn about the various components and how they work together in a basic operating session. You'll also find out what the future may hold for these machines.


Let's take a look at the main components of a typical desktop computer

Central processing unit (CPU) - The microprocessor "brain" of the computer system is called the central processing unit. Everything that a computer does is overseen by the CPU.

Memory - This is very fast storage used to hold data. It has to be fast because it connects directly to the microprocessor. There are several specific types of memory in a computer:
Random-access memory (RAM) - Used to temporarily store information that the computer is currently working with
Read-only memory (ROM) - A permanent type of memory storage used by the computer for important data that does not change
Basic input/output system (BIOS) - A type of ROM that is used by the computer to establish basic communication when the computer is first turned on
Caching - The storing of frequently used data in extremely fast RAM that connects directly to the CPU
Virtual memory - Space on a hard disk used to temporarily store data and swap it in and out of RAM as needed
Motherboard - This is the main circuit board that all of the other internal components connect to. The CPU and memory are usually on the motherboard. Other systems may be found directly on the motherboard or connected to it through a secondary connection. For example, a sound card can be built into the motherboard or connected through PCI.

Power supply - An electrical transformer regulates the electricity used by the computer.

Hard disk - This is large-capacity permanent storage used to hold information such as programs and documents.

Operating system - This is the basic software that allows the user to interface with the computer.

Integrated Drive Electronics (IDE) Controller - This is the primary interface for the hard drive, CD-ROM and floppy disk drive.

Peripheral Component Interconnect (PCI) Bus - The most common way to connect additional components to the computer, PCI uses a series of slots on the motherboard that PCI cards plug into.

SCSI - Pronounced "scuzzy," the small computer system interface is a method of adding additional devices, such as hard drives or scanners, to the computer.

AGP - Accelerated Graphics Port is a very high-speed connection used by the graphics card to interface with the computer.

Sound card - This is used by the computer to record and play audio by converting analog sound into digital information and back again.

Graphics card - This translates image data from the computer into a format that can be displayed by the monitor.
Connections: Input/Output
No matter how powerful the components inside your computer are, you need a way to interact with them. This interaction is called input/output (I/O). The most common types of I/O in PCs are:

Monitor - The monitor is the primary device for displaying information from the computer.

Keyboard - The keyboard is the primary device for entering information into the computer.

Mouse - The mouse is the primary device for navigating and interacting with the computer

Removable storage - Removable storage devices allow you to add new information to your computer very easily, as well as save information that you want to carry to a different location.

Floppy disk - The most common form of removable storage, floppy disks are extremely inexpensive and easy to save information to.
CD-ROM - CD-ROM (compact disc, read-only memory) is a popular form of distribution of commercial software. Many systems now offer CD-R (recordable) and CD-RW (rewritable), which can also record.
Flash memory - Based on a type of ROM called electrically erasable programmable read-only memory (EEPROM), Flash memory provides fast, permanent storage. CompactFlash, SmartMedia and PCMCIA cards are all types of Flash memory.
DVD-ROM - DVD-ROM (digital versatile disc, read-only memory) is similar to CD-ROM but is capable of holding much more information.

Connections: Ports


Parallel - This port is commonly used to connect a printer.
Serial - This port is typically used to connect an external modem.
Universal Serial Bus (USB) - Quickly becoming the most popular external connection, USB ports offer power and versatility and are incredibly easy to use.
FireWire (IEEE 1394) - FireWire is a very popular method of connecting digital-video devices, such as camcorders or digital cameras, to your computer.

Modem - This is the standard method of connecting to the Internet.
Local area network (LAN) card - This is used by many computers, particularly those in an Ethernet office network, to connected to each other.
Cable modem - Some people now use the cable-television system in their home to connect to the Internet.
Digital Subscriber Line (DSL) modem - This is a high-speed connection that works over a standard telephone line.
Very high bit-rate DSL (VDSL) modem - A newer variation of DSL, VDSL requires that your phone line have fiber-optic cables.
