Computer Memory

A device that is used to store data or programs (sequences of instructions) on a temporary or permanent basis for use in an electronic digital computer. It acts as the nerve center of computational activities, facilitating the dynamic interaction between software and hardware.

Bit, Byte, Kilobyte, Megabyte, Gigabyte, Terabyte

RAM is a temporary storage that can be read from or written into by the user, while ROM is a type of non-volatile memory that is used for permanent storage and cannot be easily modified.

Dynamic RAM (DRAM) is relatively slower and low-cost memory used for main memory, while Static RAM (SRAM) is faster and more expensive, often used in CPU cache memory.

The access time for every location in RAM is constant and independent of its position.

Computer memory is a device used to store data or programs on a temporary or permanent basis for use in an electronic digital computer. Its role is to act as the nerve center of computational activities, facilitating the dynamic interaction between software and hardware.

The units used to measure computer memory are: Bit (smallest unit), Byte (8 bits), Kilobyte (1024 bytes), Megabyte (1024 kilobytes), Gigabyte (1024 megabytes), and Terabyte (1024 gigabytes).

Random Access Memory (RAM) is a temporary storage that can be read from or written into by the user. It is volatile memory, with each location accessible independently and with constant access time, regardless of its position.

Dynamic RAM (DRAM) is relatively slower, low-cost memory used for main memory, with contents constantly refreshed. Static RAM (SRAM) is faster, more expensive, and used for cache memory or special registers in a CPU.

Primary Memory is relatively large memory placed outside the processor, used for data and instruction storage for the operation of the processor. An example of primary memory is RAM (Random Access Memory) and ROM (Read Only Memory).
