Terms in this set (114)
Main Memory, Buses, Input + Output devices, CPU Anatomy of a computer
Input devices Allows interaction with a computer; keyboard, mice, optical data readers, bar-
code scanners, RFID devices, pens, touch screen
Output devices Display screens, graphics cards, printers, plotters, 3D printers, speakers
Bus Communication system
, First Phase; Fetch instruction --> Decode instruction Instruction Phase
Second Phase; Execute instruction --> Store results Execution Phase
Clock Speed Series of electronic pulses produced at a predetermined rate; governs speed at
which steps are completed
Gigahertz (GHz) (Clock speed) One Billion cycles per minute
Integrated Circuit Set of electronic circuits on one small piece of semiconductor material (normally
silicon)
Multiprocessing Simultaneously execute two or more instructions; 1 Computer; Coprocessors
Parallel Processing Simultaneously execute the same task on multiple processors; 2 or more
computers; Linked to hundreds or thousands of processors
Main memory Rapidly provides working storage to the CPU; Used for program instructions and
data; Volatile
Random Access Memory (RAM) Memory where instructions or data can be temporarily stored; Volatile storage;
mounted directly to main circuit board
Cache High-speed memory; Processor can access more rapidly than main memory;
Located in the CPU; Volatile
Read Only Memory (ROM) Nonvolatile; provides permanent storage for data and instructions that do not
change
Main Memory, RAM, Cache Types of Volatile Memory
ROM, PROM, EEPROM, Secondary Storage Types of Non-Volatile Memory
Secondary storage Non-Volatile; stores large amounts of data, instructions, and information; less
expensive than main memory, slower
Magnetic Tape, Hard Drives (HDD), Virtual Tape, SSD, Types of Secondary storage
RAID
Main Memory, Input + Output devices, Buses What devices work closely with the CPU?
Thin Clients Low cost, centrally managed computers; No internal or external attached drives
for data storage
Desktop Computers Single-user computer system; Provide sufficient computer power, memory, and
storage for most business computing tasks
Workstations More powerful then personal computers; Desktop size; Support engineering and
technical users
