Memory+Explanations+of

This is the most common form of memory hardware used by a Computer.
 * Memory Explanations of **
 * //RAM//** (Random Access Memory), also called System **//RAM//** or just Memory.

When a Computer is rebooted or switched off, any information in **//RAM//** is instantly cleared.
 * //RAM//** usually comes in long thin ʹsticksʹ of set sizes that plug into the motherboard and through it provides a place for the CPU and other components to temporarily store information.
 * //RAM//** only holds information while the Computer is switched on

Aside from System **//RAM//**, the graphics card usually has its own **//RAM//** which is named**//:- Video//** **//RAM//****//.//** The CPU, and other hardware often have small memory chips called **//Caches//** to hold information temporarily. In all cases, memory is used to speed up data transfers because information can be written to, and read from memory much faster than any other form of storage. For example :- the Hard Drive or CDROM.

However, unlike **//RAM//** it can only be read from and not written to under normal circumstances, and it will not clear when the system is rebooted or switched off.
 * //ROM//** (Read Only Memory) is a permanent form of memory, and works similar to **//RAM//****//.//**

This is the program which tells the computer how to function when it is first switched on and is stored on the ROM chip located in the motherboard.
 * //ROM//** is primarily used to hold small amounts of important information, such as the **//BIOS//** (Basic Input Output System)

Certain **//ROM//**s can be written to by use of a process called Flashing, such as when the **//BIOS//** is flashed with a new version.

If we relate this function to the functions of a human body, the Memory is like our own memory with **//RAM//** being short term memory, and **//ROM//** being long term memory.

Sadly as we grow older we remember occasions from the past quite clearly and cannot recall what we were doing 5 minutes ago. Therefore the analogy can be said to be a poor one when related to age.
