Answer 1

Answer:

1 Tick five boxes to show which five of these statements are most likely to be true. (5 marks). 1. Output devices are hardware devices used to provide input to the ...

1 Request–response, or request–reply, is one of the basic methods computers use to communicate with each other, in which the first computer sends a request ...

2 Devices that convert digital signals to analog are called DAC. Analog to DigitalConverter samples the analog signal on each falling or rising edge of sample clock. In each cycle, the ADC gets of theanalog signal, measures and converts it into a digital value.

3 A desktop or laptop computer that is used on its own without requiring a connection to a local area network (LAN) or wide area network (WAN). ... When the computer is running local applications without Internet access, the machine is technically a stand-alone PC. THIS DEFINITION IS FOR PERSONAL USE ONLY.

4 A switch is a network device with multiple interfaces or ports. ... A broadcast is sent by computers when they want to send a message to all other devices on the ...

5 A metropolitan area network (MAN) is anetwork that interconnects users withcomputer resources in a geographic areaor region larger than that covered by even a large local area network (LAN)but smaller than the area covered by a wide area network (WAN).

6 The Internet is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and  ...

7 The Star Topology(Hierarchical)

When a computer sends data to other computers on the network, it is sent along the cable to a central hub or switch, which then determines which port it needs to send the data through for it to reach the proper destination. ... All cables run to a central connection point.

8 Disadvantages of Bus Topology Cables fails then whole network fails. If network traffic is heavy or nodes are more the performance of the network decreases. ... It is slower than the ring topology.

9 Being able to communicate in real-time through integrated third party tools promotes the sharing of ideas and helps boost a business' productivity; Time ...

10 In contrast, in a typical client–server architecture, clients share only their demands with the system, but not their resources . In ...
