RAM: Random Access Memory

RAM is an abbreviation of Random Access Memory. RAM is the main memory of a computer or mobile phone. It is a memory that is volatile and shows that when the computer is switched off, data are disoriented in RAM. In RAM, a user can alter or remove his data. On a device at the present, data or applications being used are kept in reserve in RAM from the hard drives because data from the RAM are loaded much quicker than the hard drives. With the upsurge in the faculty of a user’s personal computer RAM, his computer speed will upsurge. Arbitrarily from any single byte, data can be read and write and this is the reason, it is known as "random access".

Types of RAM

RAM can be classified commonly into two types,

1. SRAM:
   Static RAM is much quicker and extra costly than DRAM. As cache memory, it frequently operates. In SRAM, Information is volatile. It keeps in reserve a bit of data by using six transistor memory cells.
2. DRAM:
   Dynamic RAM is not that much quicker than SRAM. In DRAM also, information is volatile. It keeps in reserve a bit of data by using a couple of transistors and a capacitor. As it is less costly, almost all computers use DRAM.

Specifications of RAM

• RAM is a kind of storage device, which operates as the main memory.
• RAM determines the computer speed.
• RAM is very small in comparison to hard disk, both structurally as well as facility.

Advantages of RAM

• This upsurge the speed of the computer system, the RAM will be more according to the greater speed of the system.
• In comparison to hard disk, CD, DVD, FLOPPY DISK and USB, the CPU can read data quicker than RAM.
• The use of power is in very less amount in which life of battery increases.
• Not a single of its sections moves because there is no moving section in it.
• RAM can write and remove actions of functioning.

Disadvantages of RAM

• The cost of each bit of RAM is very high, as the RAM of the computer is less.
• In RAM, the data cannot be kept in reserve perpetually because it is volatile.
• It is highly costly and expensive to buy.
• In comparison to the data access from registers and cache, CPU read the data slowly from RAM.
