Answer:

3 select inputs are required to select a specific input between 5 inputs.

Explanation:

Multiplexer is used to select the inputs from different inputs to a single output. There are many types of multiplexers for different number of inputs selection. 1. 2x1 is the type of multiplexer where 2 inputs and 1 output. This is used to select between these inputs. There is one more pin to select the input between these two inputs that is called select input.

2. Another type is 4x1 multiplexer. There are 4 inputs and one output. In this type of multiplexer 2 select pins are used for selection of input bits between these 4 inputs.

For more than 4 inputs and less than 8 inputs, 8x1 multiplexer is used. this multiplexer uses three inputs for selection purpose.

Identify the programmer’s responsibility in maximizing the programs reliability by having awareness of the beneficial and harmfu

trapecia [35]

Programmers can maximize the reliability of their programs by means of functional analysis.

The form in which programmers can maximize the reliability of their programs in accordance with the awareness of the beneficial and harmful impact on society, economies and cultures is how well they did processes of functional analyses, in which they investigate on market and client needs and derive functional and non-functional parameters, which define the scope and characteristics of the program.

A good functional analysis has an influence of about 80 % on success of programs on fulfilling existing needs and solving existing problems with a reasonable efforts.
