What is Computer Memory and its types

Do you have what is computer memory? We all use computers in our homes, in offices or elsewhere. But have you ever thought that what is the device that we need to operate these machines or simply to store our data and information? If your answer is a memory device, then you have made a correct statement. But do you know how many types of computer memory? If not then this article is going to be very helpful for you.

Just like we humans need memory to remember something or for other tasks, just like computer or any other device, they also need memory to operate properly. But the thing to understand in this is that there are many different types of memory. And whose functions are also different. In such a situation it is very important to know about all of them so that we can use them properly according to our needs. So today I thought that all your doubts regarding computer memory should be cleared today through this article, so that you do not need to go anywhere else and you can understand these technical concepts very easily. So let's start without delay and know what is the fastest memory of computer and how many types are there.



A memory is like a human mind. It is used to store data and instructions. Computer memory is such a storage space in a computer, where the data that is processed and instructions that are needed for processing are stored there. Computer memory is divided into small parts of many numbers which are called key cells. Each location or cell has a unique address, which varies from zero to memory size minus one. For example, if your computer has 64k words, then this memory unit has 64 * 1024 = 65536 memory locations. The address of this memory loacations varies from 0 to 65535.

Memory is a very essential part of any computer because without it the computer cannot do even a simple task. There are two basic types of computer memory - Primary memory / Volatile memory and Secondary memory / Non-volatile memory.

Here Random Access Memory (RAM) is a volatile memory and Read Only Memory (ROM) is a non-volatile memory.

Types of computer memory
People always have doubts about the type of computer memory. Which I would like to solve today. If seen, there are mainly three types of computer memory.
The main three types of memory are

Cache Memory
Primary Memory / Main Memory
Secondary memory
Cache Memory
This is the fastest memory of a computer. Cache memory is a very high speed semiconductor memory that speeds up the CPU. It acts as a buffer between the CPU and main memory. They are used to hold the data and those parts of the program that are frequently used by the CPU. Parts of data and programs are first transferred from the disk to cache memory by the operating system, from where the CPU can easily access them.

Advantages of Cache Memory
Let's get some information about the advantages of Cache Memory.

Cache memory is much faster than main memory.
It consumes very less access time compared to main memory.
They store programs that have to be executed within a short period of time.
They store the data for temporary use.
