COMPUTER MEMORY

COMPUTER MEMORY 

This is a very important topic in whole computer syllabus . And also important topic in viava of computer. so please read must.

Computer memory is a generic term for all of the different types of data storage technology that a computer may use, including RAM, ROM, and flash memory. 

Some types of computer memory are designed to be very fast, meaning that the central processing unit (CPU) can access data stored there very quickly. Other types are designed to be very low cost, so that large amounts of data can be stored there economically.

COMPUTER MEMORY

TYPES OF COMPUTER :-   Memory are two types in computer.

• Primary memory :-  includes ROM and RAM, and is located close to the CPU on the computer motherboard, enabling the CPU to read data from primary memory very quickly indeed. It is used to store data that the CPU needs imminently so that it does not have to wait for it to be delivered.

• Secondary memory :-  is usually physically located within a separate storage device, such as a hard disk drive or solid state drive (SSD), which is connected to the computer system either directly or over a network. The cost per gigabyte of secondary memory is much lower, but the read and write speeds are significantly slower.

Classification of memory

RAM and ROM :-

RAM, which stands for random access memory, and ROM, which stands for read-only memory, are both present in your computer. RAM is volatile memory, which means that the information temporarily stored in the module is erased when you restart or shut down your computer. Because the information is stored electrically on transistors, when there is no electric current, the data disappears. Each time you request a file or information, it is retrieved either from the computer's storage disk or the internet. RAM is volatile memory that temporarily stores the files you are working on. 

ROM is non-volatile memory that permanently stores instructions for your computer.ROM is non-volatile memory, which means the information is permanently stored on the chip. The memory does not depend on an electric current to save data, instead, data is written to individual cells using binary code. Non-volatile memory is used for parts of the computer that do not change, such as the initial boot-up portion of the software, or the firmware instructions that make your printer run.
