 THE MEMORY UNIT 1 DEFINITION AND TYPES-  PRIMARY AND SECONDARY STORAGE DEFINITION OF COMPUTER MEMORY i. This is the storage location where data, programs, and information are stored. ii. The memory unit is part of the computer that holds data and instructions for processing. iii. It may also be defined as the storage space in the computer where data to be processed and instructions required for processing are stored.  Although closely associated with the central processing unit, memory is separated from it. Types of Memories in Computer The Computer Memory is of two types, they are a. Primary memory/main memory/internal memory b. Secondary memory/auxiliary memory/external memory a. Primary Memory:  The primary memory is the memory that can be directly accessed by the CPU, the CPU constantly interact with it, reads instructions stored there and executes them as required. Types of Primary memory There are two types of primary memory: i. RAM ii. ROM (i) RAM (Radom Access Memory) :  Rando

  BASIC COMPUTER OPERATION ( BOOTING)  (MEANING/DESCRIPTION), TYPES, AND COMPONENTS OF WINDOWS DESKTOP Meaning of Booting 1. Booting is defined as the processing of starting the computer. 2. Booting can also be defined as the initial set of operations that the computer performs when power is switched on. Description of the Booting Process When the computer’s power is first turned on, the CPU (Central Processing Unit) initializes itself to look for the system’s ROM BIOS (Read Only Memory Basic Input Output System) which is the first program that runs every time the computer is turned on. The BIOS performs the Power-On Self-Test (POST), which begins by checking the BIOS chip and then testing CMOS (Complementary Metal Oxide Semiconductor) RAM. If the POST does not detect a battery failure, it then continues to initialize the CPU (Central Processing Unit), checking the hardware devices to ensure they are functioning properly. Once the POST has determined that all components are functioning
