computer architecture

Von Neumann computer architecture uses two separate memory locations, one for instructions (code) and one for data.

• true

• false

Registers are

• used to output data for human consumption

• fast memory used for temporary data storage

• very slow memory used for persistent data storage

• used to perform arithmetic operations on data

The address bus is used to carry addresses to/from main memory (RAM) to/from

• an output device, such as a printer

• an input device, such as a keyboard

• the CPU

• other computers

Which of the following is an output device? Mark all devices.

• mouse

• keyboard

• printer

• audio speaker

The Arithmetic and Logic Unit (ALU) often performs the following types operations:

• arithmetic

• binary shifts

• logical

• compression

The control unit (CU) in the CPU is in charge of fetching and decoding instructions.

• true

• false

The following devices are secondary memory:

• CD

• hard disk drive (HDD)

• display monitor

• solid state drive (SSD)

Which of the following are contained within the central processing unit (CPU)?

• control unit (CU)

• Main memory (RAM)

• Arithmetic and Logic Unit (ALU)

• Registers
