• Central Processing Unit

• Central Computing Units

• None of the above

What is the Purpose of Central Processing Unit.

• Performs the basic arithmetical, logical, and input/output operations of a computer system

• Interprets and carries out the instructions, that operate a computer program

• CPU is like the brain of a computer

• All the above

What are FIVE hardware components of a computer system?

• CPU, solid state drive, sound card, audio, motherboard

• RAM, external drive, motherboard, processor, CPU

• CPU, RAM, Hard drive, Motherboard, Video card

• CPU, buses, ALU, graphics card, audio

Purpose of the Control Unit (in the CPU)

• Controls all the information

• Directs and coordinates most of the operations in the computer

• Unit that stores information

Purpose of the Arithmetic Logic Unit (in the CPU)

• Performs arithmetic calculations in the hard drive

• Performs arithmetic, comparison and other operations

• Calculates the arithmetic necessary for a computer to work

Purpose of the Register (in the CPU)

• Registers data and performs calculations

• Temporarily holds data and instructions

• Long term registry of held data

Another name for secondary memory

• Secondary information

• Secondary storage

• Secondary calculations

• Secondary output

Purpose for Secondary memory

• Data is directly accessed by the processing unit.

• It holds data or information that is currently being used by the processing unit.

• Slowest, cheapest form of storage, and data is stored permanently. It cannot be processed directly by the processor and must be first copied from secondary memory to primary memory - then the CPU can access.

• None of the above

Three examples of secondary memory

• CD's

• Hard drive

• USB Flash drive

• All the above

What are peripheral devices?

• mouse

• keyboard

• microphone

• stylus pen

• all the above
