- 2. WHAT IS A COMPUTER? A computer is a programmable machine with two principal characteristics: It responds to a specific set of instructions in a welldefined manner. It can execute a prerecorded list of instructions (a program). •
- 3. THE MODERN COMPUTER MODERN COMPUTERS ARE ELECTRONIC AND DIGITAL. THEY CAN BE DESCRIBED IN TERMS THEIR HARDWARE AND SOFTWARE .
- 4. A COMPUTER SYSTEM Hardware Software User User Software Hardware
- 5. HARDWARE Hardware refers to objects that you can actually touch, like disks, disk drives, display screens, keyboards, printers, boards, and chips .
- 6. SOFTWAR E Software is set of programs (which are step by step instructions) telling the computer how to process data. Software needs to be installed on a computer, usually from a CD. Softwares can be divided into two groups: - System SW - Application SW
- 7. SOFTWARE (CONTD.) System Software It controls the overall operation of the system. It is stored in the computer's memory and instructs the computer to load, store, and execute an application. Examples: Operating System (OS), Translators DOS, Windows, Unix etc.
- 8. SOFTWARE (CONTD..) Application Software They are Softwares written to perform specific tasks. The basic types of application software are: word processing, database, spreadsheet, desktop publishing, and communication. Examples: MSOffice, Tally, MSOutlook,
- 9. ADVANTAGES OF USING COMPUTERS Speed: Computers can carry out instructions in less than a millionth of a second. Accuracy : Computers can do the calculations without errors and very accurately. Diligence : Computers are capable of performing any task given to them repetitively. Storage Capacity : Computers can store large volume of data and information on magnetic media.
- 10. HISTORY OF EVOLUTION OF COMPUTERS Two Eras: Mechanical Era (Before 1945) Electronic Era (1945 - ) Can be divided into generations. First Generation (1945 – 1954) Second Generation (1955 – 1964) Third Generation (1965 – 1974) Fourth Generation (1975 - )
- 11. TYPES OF COMPUTERS On the basis of Computing Power & Size: Laptop / Palmtop Micro Computer / Desktop Mini Computer / Mainframe Super Computer
- 12. COMPUTER NETWORK A Computer Network is interconnection of Computers to share resources. Resources can be : Information, Load, Devices etc.
- 13. BENEFITS OF COMPUTER NETWORKS Information Sharing Device Sharing Load Sharing Mobility Fast Communication Anywhere Anytime Banking
- 14. CPU ( CENTRAL PROCESSING UNIT) • The central processing unit (CPU), also known as just a "processor”, is the "brain" of your computer. • It contains various electronic circuits.
- 16. VDU (MONITOR) This is the television-like screen where the results of a computer's tasks are displayed. Monitors come in all sizes, but most commonly they are either 15 or 17 inches (measured diagonally from one corner of the screen to the opposite corner).
- 17. KEYBOARD The keyboard looks like a typewriter. It contains all the letters of the alphabet, numbers and some special symbols. It operates like a typewriter keypad, but instead of moving an arm, which strikes the paper, it sends an electronic impulse to the computer, which displays a character on the monitor.
- 18. MOUSE • Its a device that is used to control the computer. A cable connects the mouse to the computer. • When the mouse is moved on a pad, called a mouse pad, the cursor on the screen moves. • A cursor is a small symbol displayed on the computer screen (normally a diagonal arrow that is used as a pointer) that shows you what the mouse is referencing on the screen.
- 19. PRINTE R A printer is designed to output information from a computer onto a piece of paper. There are three kinds of printers: dot matrix, laser, and inkjet.
- 20. SCANNER A scanner is a device used to copy an image off paper and convert it into a digital image, which can be saved as a computer file and stored on a hard drive. Scanners can also use a special kind of technology called Optical Character Recognition (OCR) to read text from paper and save it as an editable document file
- 21. WHAT THESE COMPONENTS DO… Power Supply – (heart) supplies power to all the circuitry and devices. Motherboard – (body) acts as a manager for everything on the computer – connects all the other components together. CPU – Central Processing Unit – (brain) this does all the work of computing.
- 22. WHAT THESE COMPONENTS DO… RAM – Random Access Memory – (short-term memory) holds data and program instructions that the computer is currently using. Hard Drive – (long-term memory) holds all of the information that needs to be stored between uses of the computer. Floppy and CD-ROM drives – (mouth/ears) allow you to give data to the computer and take data away from the computer.
- 23. WHAT THESE COMPONENTS DO… Card Slots – (fingers) Allows other components to be added to the computer. Video card – (face) Does all of the processing necessary to get stuff looking nice on screen, quickly. Sound card – (vocal cords) Allows sounds from HD or CD-ROM to be played. Network Card – (telephone) allows computer to talk to other computers over a wire.

- 28. Computer Examples of computer systems used in the textile industry Systems include: Computer Aided Administration (CAA) – computers are used for marketing, sales order processing and stock control. Computer Aided Design (CAD) – computers are used for developing designs, pattern making, pattern grading, marker production and lay planning. Computer Aided Manufacture (CAM) – computers are used for store design, lay planning and cutting, sewing and pressing. Computer Integrated Manufacture (CIM) – a system that uses computers at every stage of planning, design and manufacture. Electronic Point-of-Sale (EPOS) – a computerised system that speeds up sales transactions and monitors stock levels. In industry, the key advantages of using computers are that they: Provide an effective means of presentation Reduce the time taken to create products Improve communication Reduce repetitive work Decrease costs and increase efficiency
- 29. New Technology Many companies take advantage of new technologies, such as: Skype, instant messaging, video conferencing, blogging, E-retail, interactive design, networking sites, virtual imaging. Virtual imaging can be used to show what a design will look like before it’s manufactured, for example: •Fashion designers may use softwear like 3D Runway Designer to display their designs on virtual models •Interior designers may use mapping softwear or specialist programs to create virtual interiors.
