Coomputer Hardware Explained

With the main concept of 0 and 1, computers had changed drastically over the few years. But as though you may think that it has undergone too much change, the framework of the computer remains the same.

A computer is essentially an interlinked span of devices we call as hardware. The programs you use including the operating system itself are all software.

As said above, it is a link (like the internet, which is connected via ISPs). In a computer's inside framework, devices are linked via a "bus" which can be compared to a highway for information exchange.

All the other devices are connected in the "bus" to send and receive data. Each device also has a controller, a median for communicating the bus and the device.

Devices now, your keyboard and mouse are devices, as well as your monitors. The socket where you plug in your phone line and the USB are also devices. Among the most important are the following.

1. CPU

2. Chip Set

3. RAM

4. Graphics Card

5. Hard Drive

6. BIOS

CPU

The CPU is your computer's brain, executing the maths needed to run your whole computer.

Chipset

The chipset consists of a Northbridge and a Southbridge (for the most built). The north acts as a median to the CPU, RAM, and AGP, and the Southbridge to your hard drives, PCIs, USBs and other devices.

RAM

Random Access Memory, or memory for short, is one of few hardwares which tells how fast your computer will run. RAM is an electrically powered set of switches that is able to store and send out data as fast as the CPU requests for it to be processed. RAM is important for programs to function, since a harddrive (which also stores date) is comparably slower when it comes to sending out and writing data.

Graphics Card

Graphics Card has a similar framework, being a set of switches. But the graphics card is set to function in its own way which is to only handle the maths in order to show something on the screen (e.g. pixels and buffers, and rendering)

Hard Drive

The Hard drive or the hard disk is your primary storage device where you write your data for long time use. Same as all of them, hard drives work in the concept of 0 and 1 to store data patterns.

BIOS

The often heard BIOS stands for "Basic Input Output System." It's function is to communicate information between a computer and a human user using a keyboard, mouse, monitor, etc. The BIOS is able to do this via the use of drivers, (which are also software that has instructions on how to handle a variety of events carried out by the input/output devices).
