                         W ithout an operating system, a computer would be rendered unusable. A computer may have several types of software, but it requires operating system (OS) to run these applications. The operating system allows the software and hardware to communicate with each other in order to display the output in the brain of a computer which manages all system resources and co-ordinates all ongoing activities inside the computer.                In this session, we will explore the basic concepts of an operating system. In addition, we will discuss about user interface, editions, minimum system requirements, and features and limitations of windows vista, windows 7, and windows 8/8.1. We will also explore common features of all (windows vista, windows 7, and windows 8/8.1) operating system. Finally, we will discuss about upgrade paths and compatibility tools...

Analysing Motherboard and its Components A computer is composed of several components, where each component has its own attributes that function collectively. Motherboard, also known as system board, is the most important component around which a computer system is built. It is the largest Printed Circuit Board (PCB) present inside the system unit and is designed to hold together many important electronic components of a computer system such as the Central Processing Unit (CPU), Hard Disk Drive (HDD/Solid-state) Drive Basic Input/output System (BIOS), sound card, video card, network interface controller and power supply. All these components are connected to the motherboard via sockets, expansion slots and connectors (for I/O devices and other important peripherals). In this session, you will about the importance of the motherboard. Further, you will learn about motherboard form factors. Towards the end, you will learn about motherboard components. Let’s begin the session. M...

Input/output Devices An I/O device is any hardware that is used to communicate with the computer it is designed to send and receive data to and from a computer. Some of the commonly used I/O devices are monitor, keyboard, mouse, printer, scanner, and touchscreen. Let’s briefly learn about I/O devices one-by-one. Monitor A monitor or display is the most common output device of the computer that provides a visual output. It is also called a visual display unit (VDU). It is not possible to do anything on a computer without a display such as a monitor. A monitor is composed of a circuitry, display screen, power supply, and buttons to adjust the settings and the casing. IT receives signals from the graphic processing unit or GPU and displays it. Based on the technology used to make the monitors, they can be of three types: ·          CRT (Cathode Ray Tube) ·          LCD (Liquid Crystal Display) ...
