Memory is internal storage media of computer that has several names such as majorly categorized into two types, Main memory and Secondary memory. The memory is characterised on the basis of two key factors; capacity and access time. BASIC CONCEPTS OF MEMORY SYSTEM. Computer hardware is divided into two main categories: the system unit and peripherals. . Advanced Reliable Systems (ARES) Lab. /ColorSpace /DeviceRGB 2. The most common size is one byte. It stores the information your computer is actively using so that it can be accessed quickly. >> This section focuses on the role of computer memory, and the technology behind it. 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. /BitsPerComponent 8 1. In our simple model, the memory system is a linear array of bytes, and the CPU can access each memory location in a The computer uses a hierarchy of memory that is organised in a manner to enable the fastest speed and largest capacity of memory as shown in figure.

The slow processing of such computers did not allow for the complex memory management systems used today. RAM (Random Access Memory) – It stands for Random Access Memory.RAM is known as read /writes memory. chains of bits, that obtain their new bit chain representatives. RAM; ROM; 1.
