RAM
define it
Random access memory (in English: Random access memory/RAM) is defined as a tangible device inside the computer that stores information in a temporary manner. This memory is also considered the basis of the computer’s operation, in addition to helping the computer work on many data at the same time. It is called by many names, such as: main memory, internal memory, primary storage, and memory stick.
The name “random access” was given to it due to its ability to access any memory cell directly. In this way, random access memory differs from serial access memory (in English: serial access memory/SAM), which can only be accessed sequentially, as it stores data on String format and stored in memory cells, this is different from random access memory in which data can be accessed through commands only.
Its sections
Random access memory is divided into two main sections:
- Static memory (in English: SRAM/static RAM): This memory consists of many cells, and in each cell a binary number consisting of 0 or 1 is stored.
- Dynamic memory (in English: DRAM/dynamic RAM): Dynamic memory consists of many individual cells that store data periodically, and because it contains few components, it requires a smaller chip than fixed memory, in addition to being slow, but it has the ability to store more Memory is the opposite of fixed memory.
benefits
Random access memory is important for the computer because it helps to read and write data on the computer quickly, in addition to accessing the storage device very easily. Therefore, this memory is used to download information faster than running the same data via the hard disk (in English: hard drive). .
