Processes 01

Every digital task follows a process, from logging in to editing photos. Learn how ICT processes turn inputs into outputs, and why steps and order matter.

Fascinating Fact:

Well-designed processes improve efficiency, reduce mistakes, and make results more consistent.

In KS3 ICT, a process is a set of steps that changes data into something useful. Computers follow instructions in order, so clear processes help tasks run smoothly, whether you are sorting a list, editing an image, or handling online forms.

  • Input-Process-Output (IPO): A way to describe how data goes in, gets changed, and then produces a result.
  • Algorithm: A precise, step-by-step set of instructions used to complete a task or solve a problem.
  • Automation: When a computer carries out a process with little or no human action once it is started.
What is a process in ICT KS3?

In KS3 ICT, a process is an ordered set of steps that transforms input data into an output, such as calculating a total, sorting records, or converting a file format.

What does input-process-output mean in ICT?

Input-process-output means data is entered (input), the computer follows instructions to change it (process), and a result is produced (output), like a report, graph, or saved file.

Why does the order of steps matter in an ICT process?

The order matters because computers follow instructions exactly. If steps are in the wrong order, the process can produce errors, miss data, or create the wrong output.
