Chapter 9 8 Basic Memory Operations Memory operations require the following Data data written to, or read from, memory as required by the operation. Address specifies the memory location to operate on. The address lines carry this information into the memory. Typically n bits specify locations of 2n words.
Secondary Memory. Computer secondary memory stores data and programs permanently, even when the computer is off.The secondary memory is also known as external memory or auxiliary memory. Classification of Secondary Memory. Here is the complete classification of secondary memory Magnetic Storage. Hard Disk Drive HDD Floppy Disk Obsolete

computer memory, device that is used to store data or programs sequences of instructions on a temporary or permanent basis for use in an electronic digital computer.Computers represent information in binary code, written as sequences of 0s and 1s.Each binary digit or quot bitquot may be stored by any physical system that can be in either of two stable states, to represent 0 and 1.
The computer memory stores different kinds of data like input data, output data, intermediate results, etc., and the instructions. Binary digit or bit is the basic unit of memory. A bit is a single binary digit, i.e., 0 or 1. A bit is the smallest unit of representation of data in a computer. However, the data is handled by the computer as
Computer Memory Basics. Although memory is technically any form of electronic storage, it is used most often to identify fast, temporary forms of storage. If your computer's CPU had to constantly access the hard drive to retrieve every piece of data it needs, it would operate very slowly. When the information is kept in memory, the CPU can
It's where information is stored for immediate use. Memory is one of the basic functions of a computer, because without it, a computer wouldn't be able to function properly. Memory is also used by a computer's operating system OS, hardware and software. There are technically two types of computer memory primary and secondary.
1. Primary Memory. It is also known as the main memory of the computer system. It is used to store data and programs, or instructions during computer operations. It uses semiconductor technology and hence is commonly called semiconductor memory. Primary memory is of two types RAM Random Access Memory It is a volatile memory. Volatile memory
The basic function of computer memory is essentially to store data. Depending on the type of data it stores and the role it plays in computer operation, however, memory performs several different functions. Although all of these functions involve data storage, RAM, ROM, flash memory and hard drives each perform a
