No, not just the screen. Look at all of the other parts. Do you know what they are? Do you know what they do? If you already know - great! Give yourself a big pat on the back! But if you don't know about all the gadgets surrounding your computer, then read on and find out! . OBJECTIVES:. Define & distinguish hardware and software. Describe the functions of:. CPU. Motherboard & Daughterboards. I/O ports & devices. Operating System Software (OS). Application Software. A typical computer system irrespective of its size, class or type consists of hardware and software, integrated and harmonized together to perform computational work (scientific or military) or data processing. An interconnection network facilitates communication among these three components. . System bus is the set of physical connection in between cables and printed circuits. It is shared by different hardware components. It is an electronic pathway that the processor uses to communicate with the Internal and External devices of a computer system.. Input Unit. CPU (Central Processing Unit). CPU itself has the following three components −. ALU (Arithmetic Logic Unit). Memory Unit. Control Unit. Output Unit. Input Devices. Keyboard. Mouse. Joy Stick. Chapter 1: Computer Basics. Learning Objectives:. Understand the purpose and elements of information systems. Recognize the different types of computers. Distinguish the main software types.
