WEL COME COMPONENTS OF COMPUTER CREATED BY Mr. Siddhartha Gaikwad

INDEX :

INDEX MOTHER BOARD INPUT DEVICES STORAGE DEVICES OUTPUT DEVICES OTHER PERIPHERALS

Motherboard:

Motherboard CPU RAM BIOS Cooling system PCI Slots

1. Central Processing Unit (CPU):

1. Central Processing Unit (CPU) CPU or central processing unit is the main processing unit It determines the performance of the computer (processor speed) Can be said a BRAIN of computer Currently Pentium Chip (Processor) are most popular

2.RAM :

2.RAM One of most important part of computer Random Access Memory RAM stores information temporarily More RAM in the computer more faster computer works RAM is in the form of a chip and different vendors have developed the RAM of different capacities

3.BIOS:

3.BIOS BIOS: Basic Input/Output system is a set of instructions in ROM Used to start most basic services of computer system Computer have more than one BIOS

4. Cooling system:

4. Cooling system A cooling mechanism prevent damage to computer from heat Contains fans and sinks The CPU, Computer case, power supply, some Hard disk, some adapter cards need cooling

5. PCI slots:

5. PCI slots Slot is the space provided on motherboard used to increase functionality of computer There are RAM slots, AGP slots and expansion slots.

INPUT DEVICES:

INPUT DEVICES Keyboard Mouse Scanner Joystick Microphone

1. Keyboard:

1. Keyboard The keyboard is used to type something or input information to the computer. Connects to the system via cable or wireless connections There are different designs and models available

2. Mouse:

2. Mouse Most common input device used to give instructions to computer Connectivity via cable or wireless media Types: Track Ball, Optical mouse, IR mouse, Radio wave mouse

3. Scanner:

3. Scanner Scanners allow you to transfer pictures and photographs to your computer Used to scan the images and pictures Using software you can convert printed documents into the text that you can use in the word processor

4. Joystick:

4. Joystick Another input device used to play games Available in many shapes

5. Microphone:

5. Microphone Used to give audio input Important in video conferencing

Storage devices:

Storage devices primary storage RAM Secondary storage HDD Floppy disk Solid storage devices

1. Hard Disk Drive:

1. Hard Disk Drive Hard Disk Drive HDD is a mechanism to run disks HD is a fixed media storage device Data stored magnetically Mostly internal but some are external

2. Floppy :

2. Floppy Floppy disks stores data magnetically Disk covered by means of plastic coat Older storage device having less storage capacity

3. Solid storage Device :

3. Solid storage Device Used as external storage device Works faster than disks Data stores electrically and having USB

Output Devices :

Output Devices Monitor Speakers Printer

1. Monitor:

1. Monitor monitor is used to display the information on the screen. Monitors come in many sizes and shapes, monochrome or full colors Today most computers use LCD

2. Speakers :

2. Speakers Speaker is the audio output device Used to listen songs and other audio media

3. Printer:

3. Printer printer takes the information from the PC and transfers it to the paper of different sizes There are three basic types of a printer such as dot matrix, inkjet and laser

Other Peripheral Devices :

Other Peripheral Devices Modems Digital Camera Sound and Video Card

1. Modem:

1. Modem Modem is used for modulation and demodulation of data convert data analog to digital and digital to analog Can be internal and external Modems are measured by the speed which is called baud rate. The typical baud rate is 56Kb

2. Digital Camera:

2. Digital Camera Device used to take digital photographs Images stores on the memory chip of camera Used in video conferencing

3. Sound card:

3. Sound card Sound cards produce the sound like music and voice The older cards were 8, 16 and then 32 bits allow output device to produce audio

4. Video card:

4. Video card Alternatively referred to as a graphics card, video card, video board, or a video controller, a video adapter It allow a display device such as a monitor to display images from the computer
