Computer Drivers

Today i'll be writing about System Drivers .
DRIVERS are needed by Computer Processors to communicate with external and internal Peripherals.
When a device is connected to the Computer without its driver installed, that device/Peripheral will not be able to function.
However some Peripherals are Plug and Play i.e, they can work without you seperately installing a driver.
To install the driver for a Peripheral, you can download from the internet. Otherwise, (for Windows Os) insert the Cd/Dvd rom containing the driver, Go to the Control panel of your Computer, click on the System icon and go to the Device Manager.
Click on the device and then click install driver.

Memory (types)

The computer memory is categorised as follows;

1. RAM

2. ROM

1. RAM: RAM is an acronym for 'Random Access Memory'. This type of memory have a temporary storage i.e they can only store for a limited time. They can briefly be regarded as 'Volatile memories' because all data/information stored on a RAM is completely lost after a power failure.

This type of memory is mainly used by the computer to hold Data awaiting processing and Information awaiting delivery.

2. ROM: ROM is an acronym for 'Read-only Memory'. This type of Computer memory is used to store data permanently.

ROMs are used to store Important computer programs such as the 'BIOS'.

ROMs are sub-categorised into;

a. PROM

b. EPROM

c. EEPROM

Information on the EPROM and EEPROM can be erased (Intentionally).

Now let's do this:

What are the full meaning of the following Memory abbreviations;

a. PROM

b. EPROM

c. EEPROM
