MULTIPLE CHOICE QUESTION

30 sec • 1 pt

Which is true about the state of a switch?

0 represents off, 1 represents on

0 represents on, 1 represents off

both 0 and 1 represents on

both 0 and 1 represents off

Answer explanation

In digital logic, a switch is often represented by binary states. Here, 0 indicates the 'off' state and 1 indicates the 'on' state, making the correct choice: 0 represents off, 1 represents on.

MULTIPLE CHOICE QUESTION

30 sec • 1 pt

A group of binary digits or bits (usually eight) operated on as a unit. A unit for computer memory.

byte

bite

right

fight

Answer explanation

The correct answer is 'byte', which refers to a group of eight bits used as a unit of computer memory. The other options, 'bite', 'right', and 'fight', do not relate to computer memory.

MULTIPLE CHOICE QUESTION

30 sec • 1 pt

Which of the following is true about bits?

by grouping bits together, we can store more values.

by deleting bits, we can store more values.

by deducting bits, we can store more values.

by removing bits, we can store more values.

Answer explanation

Grouping bits together increases the number of possible values that can be represented. Each additional bit doubles the number of values, allowing for more complex data storage compared to deleting or removing bits.

1 megabyte is equivalent to what?

1024 kilobytes

1024 bytes

1024 gigabyte

1024 terabyte

Answer explanation

1 megabyte (MB) is equal to 1024 kilobytes (KB). This is based on the binary system used in computing, where each unit is a power of 2. Therefore, the correct answer is 1024 kilobytes.
