Types of Computers


Types of Computers
There are different types of computers, and they all are integral part of our lives. The categorisation is based on the most fundamental factors, including size, performance, and purpose.
Desktop Computer
A desktop computer is the widely used general-purpose PC that is not easily portable. It is meant to be kept at a single location usually on the top of a desk. It usually consists of monitor, keyboard, mouse, speakers, and system unit (or case). A desktop computer notably costs less for the same features (Processing power, storage, etc.) than a portable computer like a laptop. Figure 1 represents a desktop computer with speakers, monitor, computer case, keyboard, and mouse.

Laptop
A laptop or notebook computer is a type of PC that is small and portable, which means that it can be carried around easily. It is smaller than a desktop computer but runs the same applications as a desktop computer. It runs on rechargeable battery and can be used while on the go. The laptop has a ‘clamshell’ form factor with an attached keyboard, touchpad, and a screen. Both laptop and desktop computers run on desktop operating systems such as Windows and Mac OS X.
Figure 2 shows a laptop running on the Windows 7 operating system.

Tablet
A tablet or tablet computer is a portable PC that typically runs on a mobile operating system such an Android and iOS. It has an LCD touch-screen display, which is used for both input and output. It runs on battery like a laptop. A tablet is usually smaller than a laptop but larger than a smart-phone. It runs small and less complex computer programs call apps. Figure 3 shows a tablet (iPad) running on iOS.

Smartphone
A smart-phone is a mobile device that can perform various functions of a computer; for example, accessing the Internet and running apps. It is an ultra-portable computer that runs on a mobile operating system (such as Android and iOS). It is smaller than a tablet and can easily fir in one hand and pocket. Like a tablet, it has touch-screen interface. Figure 4 shows a smartphone (iPhone) running on iOS.

All-in-One PC  
An all-in-one PC is a slim and compact desktop computer that integrates the computer components into the monitor case. It contains all necessary computer parts such as the system unit and speakers in one unit, except the mouse and keyboard. Figure 5 shows an all-in-one PC.

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) ...

Introduction of Computer

Image
Introduction of Computer The first fully electronic computers were introduced in 1940s. They were huge machines that required many people to operate. Since then, computers have undergone many changes in size and performance. And, a few decades later came the type of computers we use today – personal computers (PC). Today, PCs are all around us. From desktop computers to smart phones, they are changing the way we live our lives. Thanks to the increase processing power, modular form factor, and vastly improved user experience, computers are being used by everyone, everywhere. Moreover, many electronic devices are increasingly using embedded computing; such devices are known as embedded computing systems or embedded computers, or embedded computers, for example, a washing machine, ATM, video game console, and so on. Essentially, embedded computing is the use of a programmable computer in a device that is not a general-purpose computer itself. In this session, you will learn...

Describing Windows Operating System

Image
                         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...
