The biology of a computer is a very complex and sophisticated piece of modern day technology.

I am going to show you the internal components of this amazing creation.

The processor is a very essential piece of any computer it is the heart of the computer.

It processes every data related action that the computer performs.

Flash memory is a very robust form of memory and it retains data in the absence of a power.

RAM is very quickly accessed for example: A word document would be taken from the main storage (Hard Drive) And put into the RAM for quick access. The data stored in RAM is volatile meaning that data is lost when power is removed.

ROM (Read only memory) is a firmware chip that is programmed with specific data when it is manufactured, The data in this chip isdoes not go when a charge is lost

EPROM (Electrically programmable read only memory) This chip can be erased withstrong UV Light

SATA Hard Drive

A SATA hard drive is a mass storage device which is connected to the computer via a SATA cable

Solid state drive(SSD)is a solid chip of memory instead of the traditional rotating disks.

SCSI

A SCSI Hard Drive works the same as a PATA or SATA Hard drive using magnetic strips but the only difference is the connecting port that they use, In this case a SCSI port.

This is a network card it has a Ethernet port so that a computer can connect to the internet via Ethernet connecting

They communicate with the processor using PCI bus.

Different types of BUS would include: Parallel, and serial, The most well known BUS would be USB.

• Type 1 cards are primarily used for adding additional ROM or RAM to a computer.

• Type 2 cards are often used for modern and fax modem cards.• Type 3 cards can be up to 10.5mm thick and because of this size it

can be used for portable disk drives.

An input device is a device that allows a user to input into a computer for example a keyboard.

Here are some examples of input device

An output device is a device which allows a user to put a command into a computer and something will come back out for example music.

The most common input/output interface would be USB because it is practically fast and quite cheap.

A not so commonly used input/output interface but is extremely fast but slightly more expensive than the common USB would be the FireWire cable.

ROM (Read only memory) is a firmware chip that is programmed with specific data when it is manufactured, The data in this chip is non-volatile.

EPROM (Electrically programmable read only memory) This chip can be erased with level of energy strong enough to break through the negative electronics blocking the floating gate.This is usually achieved with UV light at a frequency of 253.7
