Glossary:
Computer System - a set of parts including the computer that work all together to perform tasks.
Hardware - a device that is physically connected to your computer.a example is a computer monitor that allows the user to interface visually with the computer.Without it your computer would not exist and your software wouldn't run.
Software - Software means computer instructions or data. Anything that can be stored electronically is software.
Input - Any information or data that's entered or sent to the computer to be processed is considered input. Input or user input is most often sent to the computer using an input device such as a keyboard,mouse,webcam and microphones.
Output - Any information that has been processed and comes from a computer or computer device is considered output. When someone is viewing output, they're seeing it on an output device such as a computer monitor or a hard copy print out e.g monitors,speakers,lights and printers
Process - Commonly refers to a set of instructions currently being processed by the computer processor
Storage - Alternatively referred to as storage, storage media,or storage medium, a storage device is any hardware capable of holding information. There are two types of storage devices used in computers; a primary storage device, such as RAM, and a secondary storage device, like a hard drive. Secondary storage can be a removable, internal, or external storage.
CPU - Consists of 3 major components:
The ALU - carries out mathematical tasks rapidly,performs calculations and logic operations in binary form 1/0 om data from the memory unit.The ALU transforms the digital data and outputs the resulting value
The Memory Unit - consists of a small number of memory registers which will store items of data and send them to the ALU for processing.The result of processing will be copied back to the memory unit for storage
The CU -is in charge of processing.it interprets the software instruction and sends the right data and operation to the ALU . It accepts the result of the processing from the ALU and sends it back top the memory unit. the CU will keep track of the sequence of instruction and the location of each item of data and software instruction in the memory unit
Pseudocode Code - Numbered list on instructions
is a detailed yet readable description of what a computer program or algorithm must do, expressed in a formally-styled natural language rather than in a programming language

Good Shannon, keep adding new definitions as we work through the course
