# 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.

You can now go to Session 7.
