2.1.1 Fundamentals of Computer Systems

BA2 appreciate the importance of Computer Systems by developing your base understanding

1. Create a brand new folder called: OCR GCSE Computing in your My Documents folder
2. Inside that, create another new folder called 2.1.1 Fundamentals of a Computing System

RESEARCH: What is a System? What is a Computer System?

A system is a collection of parts that work together for a common purpose. For a system to be useful it must produce something - an output.

Outline of a System

Think about the input, process, output for the following systems:

• Underground railway system
• Respiratory System
• Holiday Booking System

Discuss whether the following qualify as being Computer Systems and how they do it:

• Answer Machine
• Washing Machine
• Car
• MP3 Player
• Television

TASK 1:

Construct a product of your choice that shows the definition of a system - INPUT, PROCESS, OUTPUT. Include the examples listed above. You may include non-computer based systems but remember we are particularly interested in Computer Systems.

Define and give examples of the following Computer Systems:

• Dedicated
• General Purpose (embedded systems)

What addition to the image above is included for a Computer System?

Save this as Computer Systems in your new 2.1.1 Fundamentals of a Computer System folder

TASK 2:

Research and discuss the following points of a Computer System in groups of three. Between you create a Presentation to you will be prepared to show the group. Make sure everyone in your group has a copy of your Presentation.

• Reliability
• Testing
• Standards
• Proprietry Standards
• Industry Standards
• De facto Standards
• Open Standards
• Ethical Considerations
• Environmental Considerations
• Legal Considerations

Save this as Importance Presentation in your  2.1.1 Fundamentals of a Computer System folder

SUMMARY:

Computer Systems - Input, Process, Output 

Computer Systems have developed extremely quickly in terms of human history. They have proven to be so useful that life without them would be unacceptable for most of us. Like any advance, they have generated their own special problems and we are gradually coming to terms with understanding and dealing with them.
