What is a hertz?

a unit of frequency defined as the # of cycles per second,

What is software?

a collection of instructions that enables a user to interact with the computer or have the computer perform specific tasks for them.

What is the CPU?

the fast-acting brain of the computer, executes all calculations and programs

What is non-volatile memory and how is it stored?

Non-volatile memory is typically used for the task of secondary storage, or long-term persistent storage, even when not powered. Examples of non-volatile memory include read-only memory, flash memory, ferroelectric RAM (F-RAM), most types of magnetic computer storage devices (e.g. hard disks, floppy disks, and magnetic tape). It is slow to access.

Is a CPU Register volatile or non-volatile?

Uses volatile memory

What is volatile memory and how is it stored?

Volatile data is stored in system memory (e.g., system registers, cache, RAM) and is lost if the machine loses its power, is shut down, or rebooted. Volatile data collection focuses on collecting data (primarily from RAM) that could be lost if the computer is shut down or rebooted--short term data. It is easily and quickly accessed.

What is a bit?

a binary digit, the basic unit of information/data in computing and telecommunications, either 1 or 0

What is Moore's Law? Will its predictions hold in the future?

a prediction by Intel co-founder Gordon Moore, who predicts the number of transistors on a chip will double every 2 years. It cannot hold forever, as the semi-conductor can only go so small until any signal and not the right signal will affect the chip

What is Random Access Memory (RAM)?

memory that can be accessed immediately, with a quick retrieval that does not have to be in any sequential order
