This document provides instructions and information for a Computer Tech 101 course. It includes details on two assignments to complete - one on computer parts and peripherals and another on things learned on the web. It also provides instructions on how to access an online typing tutor and login information. Finally, it covers background information on computer components like the CPU, RAM, and ROM and their functions.

4. Computer Parts and Peripherals
• Peripherals- External devices attached to
CPU that communicate with the outside world
There are three categories:
1) Mass storage devices
2) Input devices
3) Output devices
Use the words listed on your worksheet to
fill in and identify each picture.

5. Background
• During the late 1960’s, the integrated circuit was
developed. Hundreds of transistors, diodes and resistors
could be put onto a single chip. This resulted in higher
operating speeds, increased capacity, better reliability
AND lower cost. This also allowed designers to build
computer systems using “off the shelf” components and
help standardize the design of modern computer systems.

6. Inside Memory
A typical computer system consists of
three basic sections:
1) A Processor
2) Some Memory (RAM and ROM)
3) Peripherals (input/output devices)
•In bullet format record some of the differences between
Random Access Memory and Read-Only Memory

7. Random Access Memory or RAM
• Processor is able to read and write to this
type of memory
• Used for changing information or for
loading programs from a disk
• Does not keep or preserve its contents
when powered off

8. Read-Only Memory or ROM
• Processor can not change this memory
• Built into the computer at the factory
• Retains power even when the power is
turned off
• Useful for tasks such as starting up a
computer and powering down
• Also known as “firmware”

9. Central Processing Unit or CPU
Jobs:
•Carries out the instructions of a computer program
•Performs basic math, logic and input/output
operations
•Accepts instructions from the memory and executes
those instructions
•Often referred to as the “brain” of the computer
•Speed of CPU is measured in “Hertz” (GHz =
gigahertz)

10. Central Processing Unit
• Most instructions tell the processor to
take a bit of data from the memory or
a peripheral device and either change
that data or write it either to memory or
a peripheral device…(e.g. print it)

11. Processing, RAM or ROM
Complete the chart:
1) Circle the correct computer section
responsible for the task
2) Give evidence to prove your choice
is correct.
