This storage allows a computer to randomly read and write information at high speeds, but the information is lost when the computer is powered off.
What is Random Access Memory (RAM)
300
This defines a set of rules and formats a computer must use when communicating on a network.
What is a Network Protocol?
300
This device looks at the physical (MAC) address and forwards frames between different computers on a Local Area Network (LAN).
What is a Switch (or Hub)?
300
This program is loaded from the hard disk drive when the computer boots after the BIOS loads.

What is the Power On Self Test (POST).
500
This recent vulnerability allows an attacker to obtain a copy of the entire kernel address space or any memory in the computer. It exploits a flaw in out-of-order execution, a performance feature found in many modern processor chips. It is also a term used for when the core of a nuclear reactor overheats.
