Computer Terminologies Computer: An electronic device which takes input, processes it & produces results. Hardware: Computer hardware is the collection of physical parts of a computer system. Ex. Mouse Software: Organized information in the form of operating systems, utilities, programs, and applications

that enable computers to work. Ex. Microsoft WindowsComponents of computer system:

Input Device: Input device is a hardware which is used to provide data and control signals to a computer. Output Device: An output device is any piece of computer hardware which is used to communicate the

results carried out by CPU into human-readable form.

CPU: The CPU is the primary component of a computer that processes instructions. It runs the operating system and applications, constantly receiving input from the user or active software programs. It processes the data and produces output, which may be stored by an application or displayed on the screen.

The three components of the CPU are following, Arithmetic Logic Unit Control Unit Memory Unit

Arithmetic Logic Unit (ALU)There is electronic circuitry in arithmetic logic unit which executes all arithmetic and logical operations. Its function is obvious from its name. It performs arithmetic calculations like as addition, subtraction, multiplication and division as well as comparisons. The unit can compare numbers, letters, or special characters. There can be more than one Arithmetic logic unit in a CPU, and these ALUs can also be used for the purpose of maintaining timers that help run the computer.Control Unit (CU)There is circuitry in the control unit which uses electrical signals to instruct the whole computer system for carrying out or executing, already stored program instructions. Its name clearly shows that it controls and co-ordinates computer components. It extracts instructions from memory and decodes and executes them. In fact it regulates the flow of information through the processor. In short, it can be said, this component receives, decodes, stores results and manages execution of data that flows through the CPU. Its communication with both arithmetic unit and memory is inevitable.

Memory UnitMemory Unit contains Registers which are temporary storage areas and responsible for holding the data that is to be processed. They store the instructions and data in a processor. This data is further used by Control Unit. There are some registers that are set aside for specific tasks, these generally include a program counter, stack, and flags.Uses Of Computers: Computers are used in banks to keep record of transactions & financial data, in business to analyse & record data, in medical science to search drug & new technologies & to keep patient records, in education to teach & show educational resources, in media to edit & show multimedia, in travel & ticketing for reservation & financial

transactions in real time, in weather predictions for recording atmospheric & environmental data, in sports for recording & predicting, in arts & entertainment for multimedia editing & drawing, in social media for communication & sharing, in mobiles for communication, portability & multimedia, in science for research & analysis, in government departments for keeping records & e-governance, in publishing for typing, editing & communications, in daily life for making appointments, calculations & communications.

Motherboard: It is the main printed circuit board (PCB) found in general purpose microcomputers and other expandable systems used for connecting input, output & processing devices.

Operating System: An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs.

Program: A computer program is a collection of instructions that performs a specific task when executed by a computer.

Data: It is a set of values of qualitative or quantitative variables or individual pieces of information. Network: A computer network or data network is a telecommunications network which allows computers to

exchange data.Types of NetworksThere are several different types of computer networks. Computer networks can be characterized by their size as well as their purpose.The size of a network can be expressed by the geographic area they occupy and the number of computers that are part of the network. Networks can cover anything from a handful of devices within a single room to millions of devices spread across the entire globe.Some of the different networks based on size are:

Personal area network, or PAN Local area network, or LAN Metropolitan area network, or MAN Wide area network, or WAN

Personal Area NetworkA personal area network, or PAN, is a computer network organized around an individual person within a single building. This could be inside a small office or residence. A typical PAN would include one or more computers, telephones, peripheral devices, video game consoles and other personal entertainment devices.If multiple individuals use the same network within a residence, the network is sometimes referred to as a home area network, or HAN. In a very typical setup, a residence will have a single wired Internet connection connected to a modem. This modem then provides both wired and wireless connections for multiple devices. The network is typically managed from a single computer but can be accessed from any device.This type of network provides great flexibility. For example, it allows you to:Send a document to the printer in the office upstairs while you are sitting on the couch with your laptop.Upload the photo from your cell phone to your desktop computer.Watch movies from an online streaming service to your TV.If this sounds familiar to you, you likely have a PAN in your house without having called it by its name.Local Area NetworkA local area network, or LAN, consists of a computer network at a single site, typically an individual office building. A LAN is very useful for sharing resources, such as data storage and printers. LANs can be built with relatively inexpensive hardware, such as hubs, network adapters and Ethernet cables.The smallest LAN may only use two computers, while larger LANs can accommodate thousands of computers. A LAN typically relies mostly on wired connections for increased speed and security, but wireless connections can also be part of a LAN. High speed and relatively low cost are the defining characteristics of LANs.LANs are typically used for single sites where people need to share resources among themselves but not with the rest of the outside world. Think of an office building where everybody should be able to access files on a central server or be able to print a document to one or more central printers. Those tasks should be easy for everybody working in the same office, but you would not want somebody just walking outside to be able to send a document to the printer from their cell phone! If a local area network, or LAN, is entirely wireless, it is referred to as a wireless local area network, or WLAN.Metropolitan Area Network

A metropolitan area network, or MAN, consists of a computer network across an entire city, college campus or small region. A MAN is larger than a LAN, which is typically limited to a single building or site. Depending on the configuration, this type of network can cover an area from several miles to tens of miles. A MAN is often used to connect several LANs together to form a bigger network. When this type of network is specifically designed for a college campus, it is sometimes referred to as a campus area network, or CAN.Wide Area NetworkA wide area network, or WAN, occupies a very large area, such as an entire country or the entire world. A WAN can contain multiple smaller networks, such as LANs or MANs. The Internet is the best-known example of a public WAN.Components of Network:

1. Server: Server is a computer program or a device that provides functionality for other programs or devices, called "clients".

2. Workstation: A workstation is a special computer designed for technical or scientific applications. Intended primarily to be used by one person at a time, they are commonly connected to a local area network and run multi-user operating systems.

3. Channel: Channel refers either to a physical transmission medium such as a wire, or to a logical connection over a multiplexed medium such as a radio channel. A channel is used to convey an information signal, for example a digital bit stream, from one or several senders (or transmitters) to one or several receivers. A channel has a certain capacity for transmitting information, often measured by its bandwidth in Hz or its data rate in bits per second.

Internet: The Internet is the global system of interconnected computer networks that use the Internet protocol suite (TCP/IP) to link billions of devices worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies.

WWW: The World Wide Web (WWW) is an information space where documents and other web resources are identified by URLs, interlinked by hypertext links, and can be accessed via the Internet.

Intranet: An intranet is a network based on TCP/IP protocols (an internet) belonging to an organization, usually a corporation, accessible only by the organization's members, employees, or others with authorization.

Expansion Cards: An expansion card is an electronic card/board that is used to add extra functionality to a computer. It is inserted into an expansion slot on the motherboard of a computer. Expansion cards contain edge connectors that are used to create an electronic link between motherboard and card, thus enabling these two to communicate.

Port: A computer port is a connection point or interface between a computer and an external or internal device. Internal ports may connect such devices as hard drives and CD ROM or DVD drives; external ports may connect modems, printers, mice and other devices.

BIOS: BIOS (basic input/output system) is the program a personal computer's microprocessor uses to get the computer system started after you turn it on. It also manages data flow between the computer's operating system and attached devices such as the hard disk, video adapter, keyboard, mouse and printer.

Computer’s Classification: According to functionality, computers are classified as :

Analog Computer An analog computer (spelt analogue in British English) is a form of computer that uses continuous physical phenomena such as electrical, mechanical, or hydraulic quantities to model the problem being solved

Digital ComputerA computer that performs calculations and logical operations with quantities represented as digits, usually in the binary number system

Hybrid Computer (Analog + Digital)A combination of computers those are capable of inputting and outputting in both digital and analog signals. A hybrid computer system setup offers a cost effective method of performing complex simulations.

On the basis of Size, computers are classified as : Super Computer

The fastest and most powerful type of computer Supercomputers are very expensive and are employed for specialized applications that require immense amounts of mathematical calculations. For example, weather forecasting requires a supercomputer. Other uses of supercomputers include animated graphics, fluid dynamic calculations, nuclear energy research, and petroleum exploration.The chief difference between a supercomputer and a mainframe is that a supercomputer channels all its power into executing a few programs as fast as possible, whereas a mainframe uses its power to execute many programs concurrently.

Mainframe ComputerA very large and expensive computer capable of supporting hundreds, or even thousands, of users simultaneously. In the hierarchy that starts with a simple microprocessor (in watches, for example) at the bottom and moves to supercomputers at the top, mainframes are just below supercomputers. In some ways, mainframes are more powerful than supercomputers because they support more simultaneous programs. But supercomputers can execute a single program faster than a mainframe.

Mini ComputerA midsized computer. In size and power, minicomputers lie between workstations and mainframes. In the past decade, the distinction between large minicomputers and small mainframes has blurred, however, as has the distinction between small minicomputers and workstations. But in general, a minicomputer is a multiprocessing system capable of supporting from 4 to about 200 users simultaneously.

Micro Computer or Personal Computer• Desktop Computer: a personal or micro-mini computer sufficient to fit on a desk.• Laptop Computer: a portable computer complete with an integrated screen and keyboard. It is

generally smaller in size than a desktop computer and larger than a notebook computer.• Palmtop Computer/Digital Diary /Notebook /PDAs: a hand-sized computer. Palmtops have no

keyboard but the screen serves both as an input and output device.Memory: Computer memory is the storage space in computer where data is to be processed and instructions required for processing are stored. The memory is divided into large number of small parts called cells. Each location or cell has a unique address which varies from zero to memory size minus one. For example if computer has 64k words, then this memory unit has 64 * 1024=65536 memory locations. The address of these locations varies from 0 to 65535.Memory is primarily of three types

Cache Memory Primary Memory/Main Memory Secondary Memory

Cache MemoryCache memory is a very high speed semiconductor memory which can speed up CPU. It acts as a buffer between the CPU and main memory. It is used to hold those parts of data and program which are most frequently used by CPU. The parts of data and programs are transferred from disk to cache memory by operating system, from where CPU can access them.AdvantagesThe advantages of cache memory are as follows:Cache memory is faster than main memory.It consumes less access time as compared to main memory.It stores the program that can be executed within a short period of time.It stores data for temporary use.DisadvantagesThe disadvantages of cache memory are as follows:Cache memory has limited capacity.It is very expensive.Primary Memory (Main Memory)Primary memory holds only those data and instructions on which computer is currently working. It has limited capacity and data is lost when power is switched off. It is generally made up of semiconductor device. These

memories are not as fast as registers. The data and instruction required to be processed reside in main memory. It is divided into two subcategories RAM and ROM.Characteristics of Main MemoryThese are semiconductor memories or main memoriesUsually volatile memory.Data is lost in case power is switched off.It is working memory of the computer.Faster than secondary memories.A computer cannot run without primary memory.Secondary MemoryThis type of memory is also known as external memory or non-volatile. It is slower than main memory. These are used for storing data/Information permanently. CPU directly does not access these memories instead they are accessed via input-output routines. Contents of secondary memories are first transferred to main memory, and then CPU can access it. For example : disk, CD-ROM, DVD etc.Characteristic of Secondary MemoryThese are magnetic and optical memoriesIt is known as backup memory.It is non-volatile memory.Data is permanently stored even if power is switched off.It is used for storage of data in a computer.Computer may run without secondary memory.Slower than primary memories.

Storage Devices: A storage device is any computing hardware that is used for storing, porting and extracting data files and objects. It can hold and store information both temporarily and permanently, and can be internal or external to a computer, server or any similar computing device.

RAM: RAM (random access memory) is the place in a computer where the operating system, application programs, and data in current use are kept so that they can be quickly reached by the computer's processor.

ROM: Read-only memory (ROM) is a type of storage medium that permanently stores data on personal computers (PCs) and other electronic devices. It contains the programming needed to start a PC, which is essential for boot-up. It performs major input/output tasks and holds programs or software instructions.

Flash Memory: Flash memory is a type of nonvolatile memory that erases data in units called blocks. A block stored on a flash memory chip must be erased before data can be written, or programmed, to the microchip. Flash memory retains data for an extended period of time whether a flash-equipped device is powered on or off.

Port: A channel through which data is transferred between devices.USB Port; USB stands for Universal Serial Bus, which is an industry standard for short-distance digital data communications. Used for connecting keyboard, mouse & digital devices.FireWire: It is faster than USB. It is used for connecting digital devices like camera.Network Port: It is used to connect a computer with a network.Parallel Port: Used to connect printers with computer. Multiple data signals can be sent through this.Serial Port: This port is now obsolete. One bit could be transferred at a time. Earlier used for printers & connecting a mouse.Display Adapter: Generates video signal & sends it to a display device.Power Port: Used to give electrical power to electronic device.Modem: Modem stands for Modulator-Demodulator. It converts digital data to analog & vice versa. It is of two types: 1. Wireless Modem (Connects system to a wireless network) 2. Cable Modem (Connects system to a wired network)Intranet: Intranet refers to a computer network within an organization. It is used in private organizations only. Other outside people cannot access the information of the network.Extranet: It refers to a network that allows controlled access from outside the network Web Server: A computer which runs programs 24x7 for delivering web content over World Wide Web.WWW: It is a collection of hyperlinked documents stored worldwide on web servers.

Website: It is a collection of web pages. Generally it contains specific information about a person or organization. For example http://www.cbse.nic.in contains information about central board of secondary education.Domain Name: It is a unique name given to each website. Generally Domain Name System locate the Internet Protocol addresses of various websites for content.URL: Uniform Resource Locator is global address of web resources. Generally it contains the protocol, host, domain, extension & path. For example http(Protocol)://www(Host).Yahoo(Domain).co(Extension).in (Sub Domain)/index.php(Path). Exact URL: http://www.yahoo.co.in/index.phpSearch Engine: A website dedicated to search information on world wide web. For example http://www.google.comDigital Audio: Sound that is stored in the form of binary digits is called Digital Audi. We can edit, compress, convert and play these files. Foe example: .wav files, .mp3 files, .wma files.Digital video: It is a series of images recorded in the form of Binary Digits. Generally 30 frames per second or more are displayed in sequence. It could easily be edited, compressed or converted in other formats. For example: .mp4 & .avi.Speech Synthesis: Production of sound from text is called speech synthesis. Generally a text to speech system converts text to sound. For example Narrator in Windows 7 operating system..Speech Recognition: Conversion of sound to text is called speech recognition. Generally operating system supports speech recognition but Computational Linguistics play an important role in conversion. For example Ease of Access features in Windows 7 for Microsoft Office 2013 or 2016 version.Computer Security: Protection of computer system from threats is called computer security.Computer Privacy: Hiding personal details & data from others is called computer privacy.Online Predator: A person who develops contact with Internet users to exploit them is called online predator.Phishing: The act of extracting personal information for malicious use is called Phishing.Plagiarism: The act of copying someone’s work and using it with other’s name is called plagiarism.Spam: An irrelevant and unsolicited email sent by unknown sender is called a spam.1.

Unit -3 Mastering Typing1. What is touch typing?Ans: It is a method of typing using muscle memory without looking at the keys. 2. Mention some benefits of touch typing.Ans: Speed: Speed of typing increases with touch typing.Accuracy: Accuracy in typing increases with more practice.Time: Less time is taken to complete a typing task. Focus could be shifted to screen rather than keyboard.3. What is Rapid Typing?Ans: It is a software which is used for teaching adults & kids to use their computer keyboard more efficiently.4. How many stages are involved in Touch Typing Technique?Ans: In touch typing three stages are involved:Stage one deals with practicing home row of the keyboard, followed by lower & upper rows, numbers row, upper case letters & special symbols.Stage two involves memorizing frequently used syllables and typing words in it.Stage three involves typing actual text to perfect the skills acquired.5. What are the basic rules for touch typing?Ans: • The F, D, S, A, and J, K, L,; keys represent the base position. Try to return your fingers to the base position after each keystroke.• Use keyboard as per the colour code. The left index finger is reserved for all the red keys. The right index finger is reserved for green keys. Use the thumb to press Space Bar key.• For numeric data input use numeric pad of the keyboard. The base position on the numeric pad is number 5 key for the middle finger, 4 for the index finger, and 6 for the ring finger. • Upper-case letters and symbols appearing on keys in the numbers row are typed by one hand with the little finger of the other hand holding down the SHIFT key.• Do not look at the keyboard. Try to locate the right key with your fingers.6. What are the correct positions of hands & body while typing?Ans: • Keep your back straight while working on computer.• Keep your elbows bent at the right angle.

• Face the screen with your head slightly tilted forward.• There should be at least 50-80 cm of distance between your eyes and the screen. • The optimum height of the tabletop or under-desk keyboard drawer is 68 to 73 cm from the floor.• The chair and table height should be chosen so as to expose the shoulder, arm, and wrist muscles to the least possible strain. 7. What are protrusions?Ans: Keyboards usually have small marks on F and J keys called protrusions. They help your fingers locate the base position without looking at the keyboard.8. What are the guidelines for successful touch typing practice?Ans: • Do not rush at the early stages of learning. The speed will pick up as you progress.• You should establish and maintain a rhythm while typing. • Hit keys only with the fingers for which they have been reserved.• Keep your hands and fingers close to the base position. This improves typing speed and reduces stress on the hands.• Don’t look at the keys when you type. Just slide your fingers around until they find the home row marking.• Don’t hammer on the keys. Try using the minimum force possible.• To switch between upper/lower case always use the opposite hand.• Be patient and practice as often as possible. 9. What are the main elements of Rapid Typing window?Ans: The window is composed of the following controls:• Taskbar lets you set or change some basic options to start a lesson (keyboard layout, level, lesson, and background).• Three horizontal buttons in the top-right corner (Options, About and Help) can display the corresponding dialogs.• Three vertical buttons in the top-left corner (Lesson, Statistics and Lesson Editor) are used for switching between current lesson, User Statistics and Lesson Editor.• Text Panel is the area where the text to be typed is displayed. • Lesson Control Panel includes several controls to pause/resume the current lesson, enable/disable sounds, and adjust the sound volume.• Keyboard is the virtual keyboard that will help you to learn touch typing with all ten fingers.

10. How we can interpret results of Rapid Typing software?Ans: After finishing the lesson, result window appears on screen. The Results dialog window consists of two tabs called Rating and Errors. Rating window describes overall skill level between Beginner and Champion as well as words per minute, characters per minute and accuracy in percent.Error Window describes mistakes & delay in typing characters. Green letters denote right input, yellow letters stand for right input exceeding the acceptable timeframe. Red letters denote wrong inputs within acceptable timeframe. Orange letters indicate wrong inputs exceeding acceptable timeframe.11. How we can view and analyze our statistics in Rapid Typing?Ans: To open the Statistics section, choose the button in the top-left corner of the main window. The Statistics screen will open. Here, you can review your overall statistics and progress both in graphical and table view.The following options are available:• Click the button in the top-left corner of the window (or press Ctrl+1 on your keyboard) to see your CPM speed (characters per minute) progress.• Click the button (or press Ctrl+2 on your keyboard) to see your WPM speed (words per minute) progress.• Click the button (or press Ctrl+3 on your keyboard) to see how your typing accuracy changes in the different lessons.• To remove a metric from your statistics, select a lesson in the right table and click the button (or press Delete on your keyboard).On the Taskbar in the upper part of the window, you can choose keyboard layout, level and course for which you’d like to see statistics. You can also switch between the Lesson Group (that is, statistics by lessons) and Day Group (statistics by days) options in the far right drop-down on the Taskbar.12. What are the main elements of Lesson Editor Window?Ans: To open Lesson Editor, click the button in the top-left corner of the Rapid Typing window. Lesson Editor Window is composed of the following controls:• Taskbar lets you select the keyboard layout and level of the lesson you’d like to edit.• Toolbar includes buttons for adding a new lesson, inserting text from file and saving changes.• Navigation Tree shows the existing courses and lesson hierarchy.• Text Panel is the area where you can edit the text of the lesson currently selected in the Navigation Tree.• Lesson Metrics displays the number and percentage of words, characters, spaces and specific characters in the lesson.

• Keyboard is the virtual keyboard that highlights the characters used in the currently selected lesson. Lesson Editor makes all the lessons fully customizable. You can add, insert, change, and delete lessons, group them in courses, and review the corresponding metrics.13.
