Computers

A technology of change


Computer Technology

  • Everyone needs to know the components of the equipment you will be using


Hardware

  • Anything physical

  • That you can touch


Identify Computer Hardware

  • Important to know and understand the equipment you will be using

  • This class uses the DOS based Personal Computer platform


The Computer Tower

Also referred to as the CPU

Floppy Drive

Power Switch

Compact Disk

Player

Or CD-ROM

Chassis


CPU

  • Central Processing Unit

  • The intelligence of the computer

    • All processing occurs within the CPU


Inside the Chassis

Where the processing components are housed


CPU Circuitry

  • Silicon chips

    • Contain miniaturized circuitry

    • Placed on boards

    • Plugged into slits

    • Within the CPU

  • Process instructions given to the computer


Memory

  • ROM

    • Read Only Memory

    • Built into computer

    • Non-volatile (permanent)

  • RAM

    • Random Access Memory

    • Memory chips

    • Volatile – can be changed

    • Temporary while working


Memory – RAM

  • Random Access Memory


Hard Drive

  • The memory storage bank for the computer

  • Software and data stored on it

  • Size of memory storage is measured in:

    • Megabytes

    • Gigabytes


Hard Drives


Processing Cards

  • Mini-processing chips and circuits

  • Each performs a special and unique function

    • Video Card

    • Audio Card

    • Modem

    • Ethernet Card

    • Device Manager

    • Etc.


Processing Cards

  • Many Types

Video, Audio, Modem, Ethernet, Etc.


Peripherals

  • Hardware

  • Anything external (outside of) the chassis/CPU

  • Many types of functions and equipment


Peripherals

  • Anything outside of the Chassis


Two Types

  • There are two types of peripherals

    • Input

      • User sends data to the computer

      • User gets data and/or information from the computer

    • Output

  • Called I/O

    • In/Out


I/O

  • Input and Output Devices

Input

Output


Input Devices

Any Device that the operator uses to put data into the computer


Keyboard

  • Input device for individual characters and commands

  • Alpha, numeric, symbols, functions


Mouse

Input device that inputs data easier than keyboard commands


Digitizer


Floppy Drive

Portable Storage Devices

  • Either Input or Output

  • Save and transfer data and/or information between computer and portable storage device

  • Uses a corresponding disk drive


Floppy Drive & Disks


Zip Drive & Disk


CD Drive & Disk


Thumb Drive & USB Port


Image/Data Capture

  • Input devices that capture data and/or images

  • Programmed to transfer the data directly into the computer


Scanner


Camera


Barcode Reader


TV & VCR


Sound Capture

  • Devices that capture sound from an external source (peripheral)

  • Then transfer that sound as a digital file into the computer


Microphone


MIDI Devices


Miscellaneous Input Devices

  • There are a broad range of other input devices

  • Just a few are shown here

  • Perhaps you can think of something else?


Game Tools


Handheld Computers


Global Positioning Systems (GPS)


Output Devices

All hardware that the operator uses to download information


Monitor

  • Looks like a television screen

  • Displays information

    • Of a program

    • Text being input at keyboard

  • Quality and size vary


Televisions

  • Output images and sound

  • Similar to monitors


Printer

  • When you create a document in a program

    • It is a Soft Copy

  • If you want a Hard Copy

    • You need to print it

  • Printers output your information onto paper


Printer


Speakers

  • Speakers are sound output devices

  • Quality and size vary greatly


Projectors

  • Projectors output video and sound

  • Send images to an external screen


Portable Storage Media

Both I and O


Handheld Computers

Both I and O


Assignment

  • Find a computer outside of this classroom

    • State what computer it is and where you found it

    • Classify it as new, moderately new or outdated

  • List all of the peripheral devices on that computer

    • Classify them as Input or Output
