Computers

A technology of change

computer technology
Computer Technology
  • Everyone needs to know the components of the equipment you will be using
hardware
Hardware
  • Anything physical
  • That you can touch
identify computer hardware
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
The Computer Tower

Also referred to as the CPU

Floppy Drive

Power Switch

Compact Disk

Player

Or CD-ROM

Chassis

slide6
CPU
  • Central Processing Unit
  • The intelligence of the computer
    • All processing occurs within the CPU
inside the chassis
Inside the Chassis

Where the processing components are housed

cpu circuitry
CPU Circuitry
  • Silicon chips
    • Contain miniaturized circuitry
    • Placed on boards
    • Plugged into slits
    • Within the CPU
  • Process instructions given to the computer
memory
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
Memory – RAM
  • Random Access Memory
hard drive
Hard Drive
  • The memory storage bank for the computer
  • Software and data stored on it
  • Size of memory storage is measured in:
    • Megabytes
    • Gigabytes
processing cards
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 cards14
Processing Cards
  • Many Types

Video, Audio, Modem, Ethernet, Etc.

peripherals
Peripherals
  • Hardware
  • Anything external (outside of) the chassis/CPU
  • Many types of functions and equipment
peripherals16
Peripherals
  • Anything outside of the Chassis
two types
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
slide18
I/O
  • Input and Output Devices

Input

Output

input devices

Input Devices

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

keyboard
Keyboard
  • Input device for individual characters and commands
  • Alpha, numeric, symbols, functions
mouse
Mouse

Input device that inputs data easier than keyboard commands

portable storage devices
Floppy DrivePortable Storage Devices
  • Either Input or Output
  • Save and transfer data and/or information between computer and portable storage device
  • Uses a corresponding disk drive
image data capture
Image/Data Capture
  • Input devices that capture data and/or images
  • Programmed to transfer the data directly into the computer
sound capture
Sound Capture
  • Devices that capture sound from an external source (peripheral)
  • Then transfer that sound as a digital file into the computer
miscellaneous input 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?
output devices

Output Devices

All hardware that the operator uses to download information

monitor
Monitor
  • Looks like a television screen
  • Displays information
    • Of a program
    • Text being input at keyboard
  • Quality and size vary
televisions
Televisions
  • Output images and sound
  • Similar to monitors
printer
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
speakers
Speakers
  • Speakers are sound output devices
  • Quality and size vary greatly
projectors
Projectors
  • Projectors output video and sound
  • Send images to an external screen
handheld computers48
Handheld Computers

Both I and O

assignment
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
