The smallest number that can be represented in binary code is 0. In binary code, the digit 0 represents zero, while the digit 1 represents one. Therefore, 0 is the smallest number that can be represented in binary code.

8. A transistor is what determines whether or not a 1 or a 0 is present by either being "on" or "off".

True

False

A transistor is a semiconductor device that can amplify or switch electronic signals and electrical power. In digital systems, transistors are used to represent binary states, with "on" representing 1 and "off" representing 0. Therefore, it is true that a transistor determines whether a 1 or a 0 is present by being "on" or "off".

14. The four main processes of the computer are:

Input, processing, storage, output

Input, CPU, storage, output

Computer, processing, storage, output

Input, processing, view, print

The correct answer is "Input, processing, storage, output". This is because these four processes are the fundamental steps in the functioning of a computer system. Input refers to the data or instructions that are entered into the computer, processing involves the manipulation and transformation of the input data by the central processing unit (CPU), storage involves the retention of data and instructions for later use, and output refers to the presentation or display of the processed data or results.

4

On most IBM computers, a word is typically made up of 4 bytes. This means that a word is represented by 32 bits of data. Each byte consists of 8 bits, so when 4 bytes are combined, it results in a word. This is a common configuration in IBM computers, although it is important to note that different computer systems may have different word sizes.
