​INPUT operations

• This is the first event in the information processing cycle, where data is

  supplied for processing and obtaining information.

• Computer receives data and instructions.

• Data may be entered or captured electronically for processing by using

  various input devices such as computer keyboard, bar code readers,

  scanners, or other input devices.

​

Example of INPUT operations:

• The computer at Point of Sale counter accepts the Product name and price captured using barcode Scanner

​

Multiple Choice

Which of the following operation involved in information processing cycle refer to input?

• transforming data into information

• entering data or instruction into a computer using a keyboard

• display the result on the laptop screen

• saving the data, instruction and information into the hard disc

PROCESS operations

• Once the input is provided the raw data is processed by a suitable or selected

• processing method. This is the most crucial step as it allows for the processed data in the form of output to be used further.

• Computer applies instructions to data to produce information.

• The operations performed on data may involve arithmetic, comparison or logical operations which are usually done by CPU (Central Processing Unit) in a computer

​

Examples of PROCESS operations:

• computer calculates the total price of all products bought by user

​

​

Multiple Choice

Which of the following operation involved in information processing cycle refer to process?

• transforming data into information

• entering data or instruction into a computer using a keyboard

• display the result on the laptop screen

• saving the data, instruction and information into the hard disc

STORAGE operations

• This operation of information processing cycle is done after the data has

  been processed, and while the output is presented to user.

• Computer saves the information for a subsequent use or use in future.

• Storage can be done on hard disk, pen drives, compact discs or other storage media

​

Examples of STORAGE operations:

• computer stores the balance of user’s account after a fund transfer

Multiple Choice

Which of the following operation involved in information processing cycle refer to storage?

• transforming data into information

• entering data or instruction into a computer using a keyboard

• display the result on the laptop screen

• saving the data, instruction and information into the hard disc

OUTPUT operations

• The output operation involves the presenting or conveying. Computer

  presents or conveys the results of data processing to user.

• Computer sends information to people in a usable format.

• The results or output may be presented in many forms such as printed or

  displayed information, in the form of audio as well as video, and even in the form of movement.

​

Examples of OUTPUT operations:

• Displays the total amount to be paid on a POS screen

Multiple Choice

Which of the following operation involved in information processing cycle refer to output?

• transforming data into information

• entering data or instruction into a computer using a keyboard

• display the result on the laptop screen

• saving the data, instruction and information into the hard disc
