BIM Peripherals Test

What does the CPU do?

• Manages the internet connection
• Performs arithmetic and logic operations and controls the operation of the entire system.

• Stores data in the hard drive
• Displays images on the screen

True or false: Some tasks are completely controlled by the CPU, but for others it merely initiates as sequence of events which are controlled elsewhere, such as in a peripheral device.

• False
• True

What do peripheral devices do?

• Permit communication of

  information and storage of information.

• Play music
• Drive a car
• Cook food

True or false: Peripherals normally communicate through the CPU.

• True
• False

How many and what different types of peripherals are there in a computer?

• Peripherals in a computer are limited to just printers and scanners
• The number and types of peripheral devices depend on the

  main applications for which the computer system is

  intended.

• The only peripheral in a computer is a keyboard
• There are no peripherals in a computer

True or false: Excluding CPUs and

Memory all other

Input/Output devices

connected with the

computer systems are

altogether referred to

as peripheral devices

• True
• False

True or false: Modern computers perform operations very much faster than

most peripherals can generate or accept data.

• True

• False

Since it would be inappropriate to connect peripherals directly to the

CPU due to the CPU's speed, what do we do?

• A Peripheral Adapter is

  required to convert between the fast CPU and the slower peripherals

• Connect peripherals to the power supply
• Connect peripherals to the monitor
• Connect peripherals to the keyboard

What are typically required functions performed after an address comparator matches an address?

• Read from or write to a register (may be data

  register) connected to a data bus.

• Deleting the address from the database
• Restarting the system
• Sending a notification to the user

What is a peripheral adaptor?

• A device used to measure peripheral vision
• A tool for organizing cables in a computer
• A device that works as an interface between

  a fast CPU and a slow peripheral.

• A type of fruit that can be connected to a computer
