Computing Topics to Revise

1. Physical connection between network nodes. It adds the unique MAC Address and identifies the network interface cards of the source and destination computers. (5, 4)
4. Larger instruction set, used to perform tasks in a few lines of assembly code (4)
5. Each node is connected to every other node, only one node requires a connection to the internet in order to share this connection. (4, 8)
6. Controls and coordinates the activities of the CPU, directing the flow of data between the CPU and other devices (7, 4)

2. Small instruction set, fewer transistors needed, cheaper to produce (4)
3. Uses protocols relating to the application being used, e.g. HTTP for the browser. (5, 11)
5. A subroutine associated with an object. “new” is a special type of method called a constructor. Constructors define how an object is created (6)
7. An abstract data type consisting of a number of items in which the same item can occur more than once (4)
8. Used worldwide to enable computers to communicate regardless of location. (5, 5)
10. A specialised CPU that is used for rendering graphics, designed to perform simple instructions of small amounts of data (3)
