What is computer Memory
This device keeps the instructions obtained by Input Device by store it in Computer where it also goes to computer memory. Human beings have a brain to remember certain things, so Computer has memory to remember data. This memory is an integral part of C.P.U, also called Computer's Main Memory, Internal Memory or Primary Memory.
"Storing any instructions, information, or results is called memory. "
Computers have more than one memory we can normally classify them as primary and Secondary memory. Temprery Memory keeps data temporarily from being on to computer shutdown That is, when the computer suddenly shuts down or when it is electrified, the data is destroyed from the computer. It contains some very useful firmware. The process that helps to boot the computer boot is called the main memory. Secondary storage is one that keeps our data for a long time secondary storage comes in many forms. Foffi disk, hard disk, CD etc.
Bit or byte
Data stored in memory changes to 0 or 1 0 and 1 are jointly called binary digits. In short, they are also called bits. This bit is the smallest unit of measuring the space that is encircled in the computer memory.
8 Bits = 1 Bytes
1024 Bytes = 1 Kilobyte (1 KB)
1024 KB = 1 Megabyte (1MB)
1024 MB = 1 Gigabyte (1 GB)
1024 GB = 1 Terabyte (1 TB)
Types of Memory
Primary Memory
Secondary Memory
Primary Memory
Memory is the most important part of the computer where data, information, and programs are present during the process and are immediately available if needed. Are called. It is also called primary memory or main memory.
Primary memory is mainly of two types:
RAM
ROM
1. RAM (Random Access Memory)
Temprery Memory is the temporary memory of a RAM or Random Access Memory computer. Data input from keyboard or any other input device is stored in RAM before process and CPU. Is obtained from there as needed by data or programs in RAM temporarily stored Store data is erased in RAM when the computer is turned off or removed. Therefore, RAM is called Volatile or Temporary Memory The capacity or size of RAM is of many types such as 4 MB, 8 MB, 16 MB, 32 MB, 64 MB, 128 MB, 256 MB etc.
There are three types of RAM.
DRAM
SRAM
Static RAM
Dynamic RAM
Dynamic RAM is abbreviated ly called DRAM. Ram has the most simple DRAM and requires refresh quickly. Refresh means that the chip has to be remused here, it refreshes almost thousands of times a second. And each time refreshed, it reduces speed due to early refresh of the content that it first erases.
Synchronous RAM
Synchronous RAM Deram (DRAM) is faster than that. The reason for its fast pace is that it is being used by the CPU. Refresh according to the speed of the clock. That's why they transfer data faster than the DERM.
Static RAM
Static RAM is a RAM that is less refreshed. Being less refresh, it keeps the data in memory for longer. S-RAM is faster and more expensive than DERAM.
2. ROM (Read only memory)
The full name of ROME is read online memory. It is permanent memory in which programs are stored at the time of computer creation. Store programs cannot be changed and deleted in this memory, They can only be read. So this memory is called read online memory. Data stored in ROM is not lost even after the computer switches off. Hence, follicles are called non-volatile or permanent memory.
There are different types of follicles which are as follows:
PROM (Programmable Read Only Memory)
EPROM (Erasable Programmable Read Only Memory)
EEPROM (Electrical Programmable Read Only Memory)
PROM (Programmable Read Only Memory)
The full name of PROM is Programmable Read Only Memory, a memory that cannot be deleted or changed once the data is stored.
EPROM (Erasable Programmable Read Only Memory)
EPROM's full name is Erasable Programmable Read Only Memory, which is similar to prom, but the Store Program stored in it can only be erased by ultraviolet rays and new programs can be stored.
EEPROM ( Electrical Programmable Read Only Memory)
EEPROM has its full name Electrical Programmable Read Only Memory. There is also a new technology e-Iprom in which the program can be erased from memory in a powery manner.
Summary Words
Storing any instructions, information, or results are called memory.
