Q

What is the control unit?

A

Ensures all the required instructions are retrieved and interpreted in the correct sequence.
Data/instructions are transferred from the input devices or storage devices and placed in the temporary storage of registers in the CPU until the necessary data is ready to be processed in the ALU and results stored in the right place

Q

How do registers work and what do they do?

A

Registers -memory built directly into the processor , used to store data during the execution of instructions. Data which is processed within the ALU and instruction that inform the CPU as what is to happen to the data.

Q

Define ROM

A

ROM - Read Only Memory - Contains permanent instruction such as Basic Input/Output (BIOS) programme( An integral part of the computer when it is build, unlike operating systems which can be added later) When you switch on the computer checks all the expected devices are in place also check that they are properly working and load the operating system.

A

Output register
Holds output character

22
Q

What are computer ports?

A

physical points using which external devices can be connected to the computer.

23
Q

Where can you use universal serial bus (USB) port?

A

Printers
Mobile devices
Cameras

24
Q

What does a fire wire do?

A

Fire wire
Used to link devices that need high
speed transfer of large amount
of data to computer using
special cables.

25
Q

What is a network port?

A

Used to connect computers to modem, routers or local area networks.

26
Q

What is an Ethernet port?

A

Used for cable-based networks

27
Q

What is serial advanced technology attachment?

A

Allows devices such as optical and hard drives to link to the computer.This port is linked to another port on the motherboard with 7-pin ribbon cable.

28
Q

What is a channel?

A

The connection between devices on a network is called a channel.

29
Q

What is a twisted pair (TP) ?

A

A pair of insulated wires are twisted together (obviously)
Several twisted pairs are brought together to form a twisted cable
Used in telephone systems

30
Q

What does the shielded twisted pair do?

A

The STP combines shielding and cancellation and wire twisting

31
Q

What does the coaxial cable do?

A

Coaxial Cable
Used in television systems
Coaxial cable is used as a transmission line for radio frequency signals
Used in television systems

32
Q

What do fibre cables do?

A

These offer the fastest data delivery by cable. Each fibre is no thicker than a human hair. The thinner the fibre the better the signal.

The signal is sent down a glass rod or core as a beam of light.

33
Q

What does wireless technology do?

A

Wireless technology doesn’t use cables but uses radio frequency signals to transmit data

This can be between different devices including computers, printers and certain credit or debit cards

The differences tend to be the wavelengths of the Radio Frequency waves

34
Q

Name the Devices that transmit analog or digital signals over wired or wireless channels.

A

Modem - use telephone lines, convert digital signals to analogue signals.
Network hub - central connection point for all the devices in the network.
Switch - Receives packets(transmissions),processes them and forward them onto the specific device.
Router - Receives and send data on a network
Hybrid network hub - Includes internet access, wireless and wired LANs -
