- 1What is the CPU?The central processing unit is the core of every computer system and has two main components... the control unit and the ALU.
- 2What is RAM and what does it do?Random access memory... where the programs are stored and cache memory which is used to store data waiting to be processed. Is primary storage.
- 3What is secondary storage?Hold data to be kept when the computer is turned off. Are often hard drives and other devices such as flash memory drives and SSD's.
- 4What is ROM?Read Only Memory (ROM) is where the CPU looks for something to load. This is the boot sequence it is always stored in ROM in a specific place.
- 5The three parts of the fetch cycle?Fetch --> Decode --> Execute
- 6What is virtual memory?The area of the hard disk used for temporary storage of data from main memory is called virtual memory.
- 7What is the NOT gate?If 0 is input then it outputs 1 and if 1 is input it outputs 0.
- 8What is the AND gate?Tells us is both of the inputs are 1, by outputting 1 otherwise it outputs 0.
- 9What is the OR gate?Tells us if one or both of the two inputs are 1 by outputting 1, otherwise it output 0.
- 10What is an input device, example?A way of inputting data into a computer. An example is a keyboard.
- 11What is an output device, example?A way for the computer to output information often visually i.e. a monitor.
