Computer memory refers to the storage of data and instructions on a computer. There are two main types of memory: volatile and non-volatile. Volatile memory, such as random access memory (RAM), is temporary and is wiped clean when the computer is turned off. Non-volatile memory, such as hard drives and solid state drives (SSD), stores data even when the power is off.
RAM is the main memory used by the computer to store and access data that is currently being used by the operating system and running programs. The more RAM a computer has, the more programs it can run at the same time without slowing down.
Cache memory is a small amount of very fast memory that is used to store frequently accessed data. It is used to speed up the processing of data by the CPU.
ROM (Read-Only Memory) is a type of non-volatile memory that cannot be written to or modified by a user or a computer program. It stores the BIOS (basic input/output system) of a computer, which contains the instructions for booting the computer.
In addition to these types of memory, there are also external storage devices, such as USB drives and external hard drives, that can be used to store and transfer data.
In summary, computer memory is the storage of data and instructions on a computer. The two main types of memory are volatile and non-volatile. Volatile memory is temporary and is wiped clean when the computer is turned off, while non-volatile memory stores data even when the power is off. RAM is the main memory used by the computer to store and access data, while cache memory is a small amount of very fast memory that is used to speed up the processing of data by the CPU. There are also external storage devices that can be used to store and transfer data.
