What is Computer Memory
If you don't know what exactly is the definition of a computer? So let me tell you that a computer is an electronic, programmable machine or device.
A computer can also be called a binary device that processes data in 0 and 1 forms. The full name of the computer is "Commonly Operated Machine Particularly Used in Technical and Educational Research".
Computer memory is similar to our (human) brain. It is used to store data and instructions. Memory is a place of storage, where it processes data and stores instructions required for processing.
That is, in computing, memory is referred to as a physical device, which is capable of storing temporary and permanent information.
That is, computer memory is also called temporary memory or RAM, and ROM and hard drive storage are used to store permanent data in the computer.
Computer memory is used to store data and instructions of computer operating system ( Android, Unix, Linux, Windows ) hardware and software.
Let's understand what is called memory in easy language;
Definition of computer memory
Memory is an important element of a computer system. The word memory means " memory " in Hindi. It is a part in which data or information can be stored temporarily and permanently.
A computer cannot perform even a simple task without memory. Memory and data storage can be measured in kilobytes, megabytes, gigabytes, and terabytes.
Friends, there are mainly two types of memory (memory) present in the computer system;
- Primary Memory.
- Secondary memory.
What is Primary Memory:
It is called the kind of memory of the computer system that is directly attached to the computer processor i.e. CPU.
In this memory, the data of all your programs are stored in a temporary and temporary form. What you have just used in the computer, and the data is deleted when the system is turned off.
There are two types of primary memory;
Ram (random access memory).
Rom (read-only memory).
Main Memory Features
- These are semiconductor memories.
- It is known as the primary memory.
- Often the memory changes.
- Data is lost when power is turned off.
- It is a computer operating memory.
- Soon there are second memories.
- A computer cannot operate without primary memory.
What is Secondary Memory
It is a non-volatile memory and is not directly connected to the CPU (processor). In secondary memory, programs and data or information are stored for the long term or long term.
It has different types of memory. for example; CD and DVD, hard disk, floppy disk, memory cheap, etc.
Now you have understood very well that ' what is computer memory ' and its ' how many types ' it is also known.
So let's talk about how memory works? That is, understand how the data is stored in the memory:
Memory Works: How does computer memory work?
Friends, computers have basic units called bits or binary digits to store information. It is used to store information and has a value of ON/OFF or TRUE/FALSE.
All these bits processed in the central processing unit or CPU comprise millions of files. This computer acts as the brain. And the number of bits that need to be processed grows exponentially.
Each of the bits has a value of 0 or 1, which is used to store data in groups of bytes and execute instructions.
The purpose of the CPU is to process instructions. It reacts to inputs and produces outputs. Friends, there is a small amount of memory inside the CPU which is called Registers or Stacks.
That is, a computer memory serves to store temporary or permanent data given by the CPU. When you give some input to the computer, it is first processed in the CPU, then stored in the memory storage as permanent or temporary.
What is the role of computer memory?
Computer memory is a temporary storage area. It holds the data and instructions that the Central Processing Unit (CPU) requires. The program is loaded from the storage in the memory before the program is run. It gives the CPU direct access to computer programs.
That is, the role of computer memory is to store the data, which makes the program easy to run. There is no need to submit the program data again and again. Memory gives computer programs access directly to the CPU.
What do you understand by computer memory?
Friends, we have learned that computer memory is a physical part, which is used to store data or information permanently or temporarily in binary form.
- There are two types of computer memory in which the first is primary memory; is a volatile memory. This data can be stored temporarily and temporarily.
- For example RAM, ROM, and without this main memory, the computer cannot run.
- The second is secondary memory; It is a non-volatile memory, which is used to store permanent data. Computers can run without this type of memory.
- For example DVD, CD, Hard Disk, etc.
- Computer memory is reliable. That is, it gives stable and consistent results. And there may be issues of sociability as well.
