Byte
A group of 8 bits. Since there are 8 bits with two values each, the highest number of possible values is 2 to the power of 8, or 256.
Character encoding

Linux OS
Linux is one of the largest an open source operating system used heavily in business infrastructure and in the consumer space
Logic gates
Allow transistors to do more complex tasks, like decide where to send electrical signals depending on logical conditions
Open source
This means the developers will let other developers share, modify, and distribute their software for free
