A short revision course that focuses on some of the basics of any computer science study. This course offers an introduction to the concepts of hardware, software, storage, operating systems, and also the threats they face from malware and hackers, among others.
Know your algorithm from your assembler. These flashcards will help explain some of the key terms we will encounter on this course. 55 everyday terms and phrases for the budding computer scientist.
The operating systems is the program that controls all the other programs in your computer. The OS provides a user interface, so that we can interact with the other functions of the computer.
Software comprises the code that runs a program as well as the program itself. Software is sometimes used to control the hardware just as, perversely, hardware is used to control aspects of the software.
This Mindmap provides an extensive overview of the software aspect of this course. Software can come in many different formats and designed to serve every conceivable use. Some are open and some are private. Form follows function.
Hardware is/are the physical aspects of the computer, as well as the other equipment it relies on to function. This can include monitors, microphones, optical drives and any other 'piece' of machinery involved.
The Central Processing Unit is the part of the computer that runs the processes and calculations necessary for function. Memory is an important factor, and a CPU runs faster with a degree of memory cached for short-term use.
Databases contain all the information stored by the user(s). The structure of a database can vary. Data stored will depend on a number of factors including the physical capacity of the database and the security protocols involved.
Malware, hackers and spam are just some of the dangers computers face...along with spilled drinks, solar-flares and confused people who press the wrong buttons all the time. Protect your computer any way you need to.
On almost any online service, you will be invited to create an account by providing two key pieces of security information - your Username and your Password. Try not to use the same ones for every account.
Answer these ten short questions to see how much you have learned from this course on computer science. Data storage, cpu's, memory, interfaces and other terms like them will be tested.
