Input design
Input facilities the entry of data into the computer system. Input design involves the selection of the best strategy for getting data into the computer system at the right time and as accurately as possible. This is because the most difficult aspect of input design in accuracy .The use of well-defined documents can encourage users to record data accurately without omission.
For example, if a customer's telephone number is a needed input data, the slaes order form should have a specific line that is clearly labeled "customer telephone number". Having several lines labeled "customer information" would be less effective. This is because sometimes only the name and address would be filled in leaving out the telephone number.
Input design must capture all the data that the system needs, without introducing any errors. Input errors can be greatly reduced when inputting directly by using appropriate forms for data capture and well designed computer screen layout.
Design input may take many different forms, ranging from a vague concept in someone's head, roughly sketched on a cocktail napkin to detailed specifications/requirements. In general, a thing that is the subject of design activities is expected to do something, and often what it's expected to do is described in terms of limits or ranges. A building must have x square feet of floor space, have a brick exterior and conform to local building codes, e.g.. Whatever the thing is supposed to do forms the basis of design input.
Input design is an important aspect of system analysis and design that focuses on designing the methods and procedures for collecting and entering data into a computer-based information system.
Effective input design involves understanding the needs of the users and the requirements of the system, and creating an interface that is easy to use and minimizes errors. This includes defining the data to be collected, determining the appropriate methods for data entry, and specifying the formats for data storage and retrieval.
Some of the key considerations in input design include:
Accuracy: The input design should minimize errors in data entry by providing clear instructions and validation checks to ensure that the data is entered correctly.
Completeness: The input design should ensure that all required data is collected and entered into the system.
Consistency: The input design should ensure that data is entered consistently across the system, using standardized formats and terminology.
Timeliness: The input design should ensure that data is entered in a timely manner, so that it is available when it is needed.
Overall, input design is critical to the success of a computer-based information system, as it ensures that the system collects and stores accurate, complete, and consistent data.

Output: Output is the term denoting either an exit or changes which exit a system and which activate/modify a process. It is an abstract concept, used in the modeling, system(s) design and system(s) exploitation.Input: Input is the term denoting either an entrance or changes which are inserted into a system and which activate/modify a process. It is an abstract concept, used in the modeling, system(s) design and system(s) exploitation. It is usually connected with other terms, e.g., input field, input variable, input parameter, input value, input signal, input port, input device and input file (file format).

output
There is a definite contrast between system input and system output. System input refers to raw data which is fed into the system while system output is processed data which is released by the system.
output.
In a positive feedback system, the output increases the input.
payroll system with input
Any system you design will have an input and an output. The output will connect to the input of another system which will load it, so when you are designing any system you have to consider how loading it will effect the circuit performance.
Design
basic input output system (BIOS)
The output design during system design usually communicates all the important milestones and problems that arise during system testing. Output design proposes to the system; some remedies to various possibilities. For example, a system can print any error message that occurs and report it to an administrator.
