1A3 Block 3 review

Data unit composed of 8 bits (8b)

A programmable integrated circuit that contains all or most of the function of a CPU

A device distinct from its method of storing data; most used type of secondary memory

This connects all the parts of a computer together

A type of storage device that uses magnetism to store data

In order, what are the 4 steps computers use to work

This bus transfers or carries the actual data back and forth from the CPU to the memory

A data storage device that uses special ICs similar to flash memory, to store data permanently

This stores important data so future requests for it are rapidly available

A tiny device that receives two inputs and only one output

Non-volatile memory that can be electronically erased and reprogrammed

The main supply line between a power source and the equipment; simply a conductor

This bus specifies a physical address for data

A set of instructions that puts a computer to work

This is an electrical circuit that links one device to another

An internal I/O interface socket on the motherboard that attaches additional circuit boards

A disk drive that uses EM waves as part of its data reading and writing process

A computer geared toward the average consumer for personal use

This is a serial interface standard design used to connect internal hardware devices to a motherboard

The number of bits each bus can transfer regardless of whether the bus works in serial or parallel

These are the essential circuits sometimes known as chips or microchips

Non-volatile memory the CPU can read but not change as easily

A portable device that plugs into a specific port and stores data using ROM technology

The preferred memory of computer system’s because of its speed; no moving parts

High-speed network limited in geographical scope

These help scientists by processing immense calculations

A component that supplies DC power to electric loads. Converts AC into DC

Data flowing one bit at a time over a bus

A serial interface standard for attaching external I/O devices to a computer

Which of these are volatile

External interfaces that connect speakers or headsets to output sound

Software used to operate and maintain the computer system

The means from which a computer store data

A computer that provides services and information to other hosts

A program (or set of programs) that manages a computer’s hardware and software

Which of these are non-volatile

Software written for a unique and specific purpose

A low-level program that shows an OS to control devices

This serves as the interface between the motherboard and a drive

A unit of measurement expressed as either a 0 or 1 in binary code

Large companies use these to perform critical tasks that involve bulk data processing

The heart and brain of a computer; performs the basic operations of the system

Refers to the quality of a video display device

An electronic or mechanical device, under the control of instructions stored in its own memory

Small areas within the CPU used to store temporary results and control data

A standard that defines the connection of storage devices such as drives

An output external interface that helps provide video output through a display device

The first system software a computer system runs

This portion of the CPU performs all arithmetic and logical operations

This directs the operations of the CPU itself to include Input and Output (I/O)

A collection of unorganized facts

This bus carries commands to and from the CPU to all devices connected to the motherboard

A chip or circuit that provides the timing signals which synchronized all operations of the motherboard

Data flowing several bits at a time over a bus

The enclosure that houses all the computer’s components

Non-volatile memory that serves as permanent storage for a computer system

These are circuits that can store data

Volatile primary memory that serves as temporary electrical storage space for instructions and data
