Computers in

the Textiles Industry

MODERN COMPUTERS ARE ELECTRONIC AND DIGITAL THEY CAN BE DESCRIBED IN TERMS

THEIR HARDWARE AND SOFTWARE.

THE MODERN COMPUTER

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

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.

Examples: MSOffice, Tally, MSOutlook,

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.

HISTORY OF EVOLUTION OF COMPUTERS

TYPES OF

COMPUTERS

On the basis of Computing Power & Size:

 Laptop / Palmtop

 Micro Computer / Desktop

 Mini Computer / Mainframe

 Super Computer

COMPUTER NETWORK

 A Computer Network is interconnection of

Computers to share resources

 Resources can be : Information, Load, Devices etc

BENEFITS OF COMPUTER NETWORKS

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.

INPUT &OUTPUT DEVICES

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)

 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

• 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.

MOUSE

 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

 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

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.

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.

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.

COMPUTER APPLICATION IN APPAREL INDUSTRY

 CAA

 CAD

 CAM

 CIM

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.

•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
