  Types of Computer Buses 1. Internal Bus:  The internal bus (sometimes called the front-side bus, or FSB for short). The internal bus allows the processor to communicate with the system's central memory (the RAM). 2. Expansion Bus:  The expansion bus (sometimes called the input/output bus) allows various motherboard components (USB, serial, and parallel ports, cards inserted in PCI connectors, hard drives, CD-ROM and CD-RW drives, etc.) to communicate with one another. However, it is mainly used to add new devices using what are called expansion slots connected to the input/output 3. Address bus:  carries memory addresses from the processor to other components such as primary storage and input/output devices. The address bus is unidirectional, that is, data only move in one direction. 4. Data bus:  carries the data between the processor and other components. The data bus is bidirectional, that is, data can move in two directions (to and fro simultaneously) 5. C...

 CLASSIFICATION/MEANS OF TRANSMITTING INFORMATION   INVENTION OF PRINTING- RADIO AND TELEVISION- COMPUTER STAG E Evolution of ICT has passed through different stages. They are: (i)                   Invention of printing stage (ii)                 Invention of radio and television stage (iii)               Invention of computer stage (i)                   Invention of printing stage: This is the use of machines to produce copies of information. Printing technology made it possible for a large quantity to be produced at the same time. (ii)             Invention of radio and television stage: Radio a method of information transmission by the use of electromagnetic waves (without using a connecting wire) while television is transmitting information to the people using radio and pictur...

 COMPUTER SOFTWARE 1 (DEFINITION, TYPES, TRANSLATORS AND UTILITY SOFTWARE) DEFINITION OF COMPUTER SOFTWARE Software is a set of instructions and procedures passed to the computer to perform certain activities or task. Types of Software Software is divided into two broad groups, these are: 1. System Software 2. Application software 1.  System Software:   It can be defined as programs that help run the computer hardware and software. The system software consists of programs, written by manufacturers, which contributes to the proper control and good performance of the computer system. System software generally comprises three groups. These are: a. Operating system (Examples Disk Operating System (DOS), Microsoft windows, UNIX, LINUX, MAC, Android, iOs etc b. Utility software ( Some examples are antivirus software, file management tools, compression tools, disk management tools, etc.) c. Translators (Translators are compiler, assembler, and interpreter) (i) Compiler :  a...
