There are two main types of RAM : Dynamic RAM (DRAM) and Static RAM (SRAM). DRAM (pronounced DEE- RAM ), is widely used as a computer's main memory. ... SRAM (pronounced ES- RAM ) is made up of four to six transistors.
SRAM :- SRAM is a type of semiconductor memory where the word "Static" indicates that it does not need to be periodically refreshed to retain its data. SRAM is more expensive, but faster and significantly less power hungry than DRAM . due to a more complex internal structure, SRAM is less dense than DRAM and is therefore not used for high-capacity, low-cost applications such as the main memory in personal computers. Static RAM is mainly used to make the CPU's cache.
Microcomputers: Microcomputers are more commonly known as personal computers (PCs). The microcomputer is generally the smallest and least expensive of the computer family. Originally, these computers were designed only for individual users, but nowadays they have become powerful tools for many businesses that, when networked together, can serve more than one user. Microcomputers include the following types: · Desktop Computers · Notebook Computers · Laptop Computers · Handheld Computers i. Desktop Computers: ...
