Computing CT 2

Question 1

How is data in computer systems represented?

Answer 1

Data in computer systems is represented in binary form. Programmers use Hexadecimals (Base 16)

Question 2

How is computer memory and sorage measured?

Answer 2

Computer memory and storage are measured in different units. Bit = 1 digit, Nibble = 4 bits, Byte = 8 bits, 1000 bytes = 1 Kilobyte, 1000 Kilobytes = 1 Megabyte, 1000 Megabytes = 1 Gigabyte, 1000 Gigabytes = 1 Terabyte.

Question 3

How will and AND gate produce an output and how will an OR gate produce an output?

Answer 3

An AND gate will only produce an output of 1 if both inputs are 1. OR gate will produce an output of 1 if one of the inputs is 1

Question 4

What is the Binary calculation table?

Answer 4

The binary calculation table is 128 64 32 16 8 4 2 1

Question 5

What do you do when adding binary?

Answer 5

When adding binary 0+0 = 0, 0+1 = 1, 1+1 = 0 carry 1, and 1+1+1 = 1 carry 1.

Question 6

How many basic logic gates are their?

Answer 6

There are three basic logic gates, AND, OR and NOT. Every logic circuit can be made up from these three logic gates.

Question 7

What is a truth table?

Answer 7

The output of logic gates can be shown through truth tables. The truth table shows what the output will be, based on the input.
