Module 1 lecture
Module 1 OverviewThe focus of this module is on
safety. Keeping you and the equipment safe is
emphasized. Of importance are the vocabulary
terms. They are the bold face words time should
be spent to make sure you understood them.
Computer basics are covered in this module along
with the history of the Internet. Math for the
digital age is complex. It is important that you
know how the conversions are done. The labs and
worksheets provide practice.
3
Students completing this module should be able to

• Identify the basic features of the Windows
  operating system and the elements of the Windows
  desktop.
• Define several vocabulary words that are
  important to the technician.
• Convert between binary, decimal and hexadecimal.
• Describe analog, digital, and algorithms.
• Safety is the first priority when working with
  computers. This module will detail safety
  procedures that pertain to the labs used
  throughout this course and in the workplace

1.2.7 Switching Between Windows

• When more than one window is open, the user can
  switch between windows by pressing Alt Tab.
• Give it a try, its a great way to move about or
  to copy and paste data between files.

Hold down the Alt button and press Tab button
several time to move from window to window.

1.5.3 Boolean Logic Gates AND, OR, NOT, NOR, XOR

• Computers are built from various types of
  electronic circuits. These circuits depend on
  what are called AND, OR, NOT, and NOR logic
  "gates".
• These gates are characterized by how they respond
  to input signals.

For this course you only need to know how to work
with the diagram on the next slide.
25
1.5.3 Boolean Logic Gates AND, OR, NOT, NOR

• There are only three primary logic functions
  AND, OR, and NOT.
• The AND gate acts as follows if either input is
  off, the output is off.
• An OR gate acts as follows if either input is
  on, the output is on.
• A NOT gate acts as follows if the input is on,
  the output is off, and vice versa.
• The NOR gate is a combination of the OR and NOT
  gates and should not be presented as a primary
  gate.
• A NOR gate acts as follows if either input is
  on, the output is off.

26
Practice NOT, AND, OR, NOR

• (1 or 0 ) and 0
• ( ____ ) and 0
• ____
• 2) 0 and (0 and 1) or 0 NOR 0
• 0 and ( _____) or 0 NOR 0
• 0 and ____ or 0 NOR 0
• ___ or 0 NOR 0
• ___ NOR 0
• ____
