4 Things common to all computers

• INPUT, STORAGE, POWER MANAGEMENT, OUTPUT

• INPUT, EXECUTE, PROCESSING, OUTPUT

• INPUT, STORAGE, PROCESSING, OUTPUT

• DATA TYPE, STORAGE, PROGRAMMING, OUTPUT

SERIES OF COMMANDS

• PROCESSING

• FUNCTION

• STORAGE

• ALGORITHM

WHICH OF THE FOLLOWINGS IS NOT RELATED TO BINARY DATA

• TRUE - FALSE

• 0 - 1

• YES - NO

• DO - DON NOT

ON-OFF STATE OF A SINGLE WIRE IS CALLED

(a)  

IN DECIMAL NUMBETR SYSTEM WE HAVE DIGITS FROM ... TO ...

• 1 - 10

• 0 - 9

• 1 - 100

• 0 - 99

WITH 8 BITS YOU CAN STORE NUMBERS BETWEEN ... AND ...

• 1-255

• 1-100

• 0-255

• 0-100

a tiny physical device that acts like a digital switch in computers

• MODEM

• SWITCH

• UPS

• TRANSISTOR

Computers use ... to transform the 1s and 0s from input wires.

• ELECTRICITY

• TRANSISTORS

• LOGIC GATES

• WIRES

IF THE INPUT IS 1, THE OUTPUT IS 0:

• NOT gate

• XOR gate

• OR gate

• And gate

• 0

• 1 1

• 1 0

• 1
