What is a Computer Memory :: It stores or saves instructions and results, the results can be saved permanently as well as temporarily. << The fast, easy way to improve your laptop's performance. Faster than secondary memories. This chapter also covers the logical layout of memory, defining the various areas of memory and their uses from the system’s point of view.

Here is a list of some characteristics of computer memory. The system memory is the place where the computer holds current programs and data that are in use. Every character is converted to its corresponding binary form. 2.0 COMPUTER SYSTEMS 2 ... for the computer to process and store in memory. System software is responsible for controlling, integrating, and managing the individual hardware components of a computer system so that other software and the users of the system see it as a functional unit without having to be concerned with the low-level details such as transferring data from memory to disk, or Some characteristics are true for both kinds of memory; others are true for just one. 1. Computer random access memory (RAM) is one of the most important components in determining your system’s performance. Main memory is as vital as the processor chip to a computer system. /Height 312 Data is lost in case power is switched off. COMPUTER MEMORY Memory is an essential element of a computer. Then we’ll look at the various types of memory, speeds, and packaging of the chips and memory modules you can buy and install. generates 32-bit addresses, it can access upto 2. The diagrammatic representation of the classification of computer memory is shown below: Fig1: Classification of the Computer Memory The performance of the computer system depends upon the size of the memory. R��� �)@)JP /Width 350 A. The memory is characterised on the basis of two key factors; capacity and access time. Load programs faster. BASIC CONCEPTS OF MEMORY SYSTEM. It is known as main memory. endobj /Type /XObject 16-bit addresses is capable of addressing upto 216 =64K memory locations. It is a volatile memory as the data loses when the power is turned off. /Type /ExtGState It generally refereed as main memory of the computer system.

The major hardware components of a computer system are: Processor Main memory Secondary memory Input devices Output devices For typical desktop computers, the processor, main memory, secondary memory, power supply, and supporting hardware are housed in a metal case. Fast computer systems have both a fast processor and a large, fast memory. /ca 1.0 Jin-Fu Li, EE, NCU 4 Basic Concepts ¾The maximum size of the memory that can be used in any computer is determined by the addressing scheme For example, a 16-bit computer that generates 16-bit addresses is capable of addressing up to 216=64K memory locations.
