Immediate Access Store
What's clock speed measured in?
increasing the clock speed.
disadvantage of overclocking.
RAM memory is
Volatile memory loses integrity after a power loss. It is directly accessible by the CPU and is used to hold instructions and data for processes.
ROM Memory is
Magnetic, Optical, Solid State
3 types of storage devices
2 or more computers connected together to share information
Application Specific Integrated Circuit
CPU operation depends upon the
to read an instruction from memory for the Control Unit to decode.
the Control Unit signals the ALU to perform the request and store result in register.
Human Computer Interface
the person for whom a hardware or software product is designed.
a number of integrated circuits that allow the processor to communicate with other components within the computer.
increments address value sent to external memory to fetch the next instruction.
decodes instructions read from memory, enables data to and from ALU, internal registers, and external devices.
memory stored on a chip which loses data when the power is turned off.
Graphical User Interface
special ROM memory internal to the device which carries out more complex math operations.
American Standard Code for Information Interchange
A graphical representation of procedural pathways showing system processes for the definition, analysis, or solution of data-processing.
Enables a programmer to use mnemonics instead of numbers thereby is more easily understood by humans.
Interpretted directly in hardware, consists entirely of strings of 1s and 0s stored in registers and are almost impossible for humans to read and write.
The microprocessor instruction set is
specific to that particular chip model.
the process of entering data into the computer via an input device.
the process of saving data and instructions in memory over time permanently.
the task of performing arithmetic and logical operations.
the results of system operation in the form of data that has been processed into a useful format.
The manner in which instructions are executed and operations are performed.
symbolic code in the form of names assigned to a machine function.
Universal Serial Bus
High Definition Multimedia Interface
an interface between the computer and other computers or peripheral equipment.
the fundamental unit of computer storage.
The 5 functional units of the computer
input, output, storage, central processing Unit, arithmetic and logic, control.
memory stored on a chip which does not lose data when the power is turned off.
