RAM- RANDOM ACCESS MEMORY

RAM (pronounced ram) is an acronym for random access memory, a type of computer memory that can be accessed randomly that is any byte of  memory can be accessed withoput touching the preceding bytes. RAM  is the most common type  of memory found in computers and  devices such as printers.

Types of RAM 

TWO TYPES OF RAM:

• DRAM (DYNAMIC RANDOM ACCESS MEMORY) -The term dynamic indicates that the memory must be constantly refreshed or it will lose its contents.                                                   
• SRAM (STATIC RANDOM ACCESS MEMORY) -the term static is drived from the fact that it doesn't need to be refreshed like dynamic RAM.

{The two types of RAM differ in the technology they use to hold data, with DRAM with being the more common type in terms of speed , SRAM  is faster. DRAM needs to be refreshed which is what it faster than DRAM.

DRAM supports access times of about 60  nanoseconds, SRAM can give access times as low as 10 nanoseconds despite SRAM being faster it's not as commonly used as DRAM because it's more expensive. both types of RAM are volatile meaning that they lose their contents when the power is turned off.}
