This component inside the CPU performs arithmetic and bitwise logical operations on integer binary numbers.

A small set of data holding places that are part of a computer processor. these can hold instructions, a storage address, or any kind of data.

System software that manages computer hardware and software resources and provides common services for computer programs.

A unit of measurement of the size of information on a computer or other electronic device. One of these is equal to 8 bits and can store one character such as a number or letter.

A chart of a logical operation's input and outputs.

This components inside the CPU directs operation of the processor.

The portion of machine language instruction that specifies the operation to be performed.

An attempt to acquire sensitive information such as usernames, passwords, and credit card details (and sometimes, indirectly, money), often for malicious reasons, by masquerading as a trustworthy entity in an electronic communication.

A common unit of measurement for the size of information on a computer or other electronic device. One of these is a trillion bytes.

An elementary building block of a digital circuit. It usually has two inputs and one output.

This component holds and allows communication between many of the crucial electronic components of a system, such as the CPU and memory.

A register where intermediate arithmetic and logic results are stored.

An umbrella term used to refer to a variety of forms of hostile or intrusive software.

A form of computer data storage allowing both read- and write- procedures, and allowing bytes of memory to be accessed without touching the preceding bytes.

The standard language that represents each character (letters, numbers, and symbols) as a number from 0 to 255.

A component that stores data so future requests for that data can be served faster.

Set of instructions executed by a computer's CPU. Each instruction performs a specific task, such as load or jump.

This type of software is used to do maintenance on the computer? One example is virus protection.

Memory hardware that allows fast access to permanently stored data but prevents addition to or modification of the data.

A base 2 number system where the only digits are 1s and 0s.

A communication system that transfers data between components inside a computer or between computers.

The time between two adjacent pulses of the oscillator that sets the tempo of the computer processor. This can be measured in GHz.

This interdisciplinary field develops methods and software tools for understanding biological data.

The set of routines stored in read-only memory that enable a computer to start the operating system and to communicate with the various devices in the system

a four process cycle including Fetch-Decode-Execute-Store that is repeated by the computer's processor.
