8 Summary of Session 6

In this session, you have looked at how a processor is given instructions. There are two broad categories of computer programs: application software that enables a computer to perform specific tasks, and operating systems that manage the sharing of resources amongst the various programs.

In flowcharts, you saw one common technique of capturing the breakdown of a large task into smaller steps that can be written as a computer program.

Finally, you were introduced to a couple of special purpose computer languages in HTML and CSS, that are used by web browsers.

In the next session, you will look some more at the internet.
