Memory

 

Memory

All the operations of the computer are done by its yacht.  Although the smallest size data is registered in iChat for temporary storage, that cannot store basic instructions, complete programs, and data. Only a few bytes of data can be stored in the register.  In addition to registers to store thousands of bytes of programs and data. The computer needs apart, this part is called memory. That is the part of the computer that stores programs, data, and results are called memory.

The memory of a computer system can be divided into two main parts:

 1.  Primary memory and

 2.  Secondary memory

Primary Memory A computer's primary memory is a high-speed memory built on semiconductor technology.  Primary memory is used to store programs and data during computer operation. Primary memory can be divided into volatile and non-volatile.

The semiconductor memory that loses stored data when the power supply is turned off is called volatile memory.

And even if the power supply is cut off, all the stored data of the semiconductor memory cannot be erased, it is called non-volatile memory.  Primary memory is available in the market in the form of IC and is placed on the main circuit board known as the motherboard of the commuter. Primary memory we can compare with how many chambers are equipped one after the other.  Data can be written (right) in each cell and the stored data can be read from the cell.  The cells are called locations.  The location in which the data is to be stored or the data to be read from is indicated by the serial number of the locations.  These serial numbers of locations are called memory addresses.

 

There are two main types of primary memory:

 1.  RAM

 2.  Rom

1.  RAM: Read/write a memory made with RAM semiconductor technology, that is, the data stored in this memory can be read as well as the data can be written and stored in this memory if necessary.  The data in this memory can be deleted and new data can be saved. RAM is abbreviated as random access memory because data can be read from any location of RAM at any time or data can be written to any location.  Besides, when the power supply of the RAM is increased, the complete data is erased, so the RAM is also called volatile memory.

 

RAM can store data as long as there is a power supply.  RAM is usually found in the form of chips on small circuit boards. These are called memory modules.  RAM modules with capacities of 1 gay, 2 gays, 4 gays, 6 gay, 6 gay, 16 gay, 32 gay, 64 gays, 128 gays and 256 gays have been used in the computer.  At present, 64GB, 128GB, and 256GB memory modules are available in the market and are being used in computers.

2.  Rom: ROM is a kind of permanent semiconductor memory.  This memory is made in the form of IC.  Data or programs are saved during creation. Programs that are essential and frequently needed to start a computer system are stored in the ROM.  This program is called BIOS.  The microprocessor on the computer system first executes the ROM programs.  Then the ROM program creates an environment for the execution of other programs.  Once the data is stored in the ROM, it is called permanent memory as it cannot be changed.  It is also called non-volatile memory as the data of this memory cannot be erased even if the power supply is cut off.

  

The information stored in the ROM can only be read but the user cannot write any information in the ROM, so this memory is called jabdhaf nghasu gabasartu for short.  The program stored in the ROM is called firmware because the manufacturer fills the program in it while making the ROM.
