What is data?

Data is the representation of a fact, a figure, or an idea.

What is a machine cycle?

A machine cycle is the process of the CPU getting the data/information from the RAM. After it gets data from the RAM it decodes the instructions into something the computer can understand. After decoding the instructions, the CPU stores the results back into system memory as the last step of the machine cycle.

What is a petabyte and what computers use those?

A petabyte (PB) of data is 1,000 terabytes. Many business computers can store up to a petabyte of data.
