What is a computer?
An electronic device that receives input, processes it and provides an output in the desired format.
An electronic device to do homework, play video games or surf on the internet.
An electronic device that receives input, stores or processes the input and provides an output in the desired format.
Listening to audio through the speakers is an example of input.
Yes, because you're inserting data into the computer.
No, because you're not inserting data into the computer.
I don't know.
Printing a document is an example of output.
Yes, because it is the result of processing data.
No, because it's not the result of processing data.

What is it called when you store/access data, programs & files over the internet?
Hard Drive
Flash Drive
Central Processing
Cloud Computing
Which of the characteristics listed below applies to RAM
it's called working memory Or main memory or immediate access memory
It’s volatile (looses storage capability when there is no flow of electricity) thereby only allowing it to hold data and instructions (program) temporarily while processing takes place
It also holds data that results from processing data, which is waiting to be output or stored in a secondary storage.
It allows for the computer to perform multitasking and is directly accessible to the CPU
it performs large input/output (I/O) tasks and protects programs or software instructions
Which of the characteristics listed below applies to ROM
it permanently stores data
It’s volatile (looses storage capability when there is no flow of electricity) thereby only allowing it to hold data and instructions (program) temporarily while processing takes place
Holds the data and instructions necessary for starting up the computer when it’s switched on
These instructions are fixed at the time of manufacture, i.e. it is hard-wired into the chip
it performs large input/output (I/O) tasks and protects programs or software instructions
True or False: A machine cycle is the sequence of instructions performed to execute one program instruction
True
False

Retrieve programs instructions from the main storage.
Give commands to various components of the computer.
Control the sequence of operations.
Coordinate various components of the computer during execution of a program
performs arithmetic and logical operations (decisions). The ALU is where calculations are done and where decisions are made
