Unit 1.3 Wired & Wireless Networks: MCQs 2

What is meant by latency in the performance of a network? (6-9)

• The amount of time data takes to travel from the source to the destination
• The maximum rate that data can be transferred at
• The number of errors that are found in a data packet after transmission
• The route a packet takes when it is being transmitted

Which if these terms refers to the maximum rate at which data can betransferred? (1-4)

• Error detection
• Packet switching
• Bandwidth
• Transmission media

What is meant by a data packet? (6-9)

• A unit of data that travels along a network
• The number of error found in data when it has been transmitted
• The data a computer needs to connect to a network
• A connection point in a network that allows data to be shared

What is meant by a virtual network? (3-6)

• A network that is controlled by a central server
• A network that is used only to share software
• Controlling computers and devices remotely using the internet
• A network that is built using only wireless connection points

Which of these is a benefit of virtual network? (6-9)

• They have a higher level of security than other remote connections
• There is no need for any hardware to connect a computer to a network
• There is no need for any software to connect a computer to a network
• They stop any errors occurring in the transmission of data in a network

Which of these is a correct definition of DNS? (6-9)

• An internet service that is used to detect errors
• An internet service that stores data in large quantities for different companies
• An internet service that provides a messaging service for users to communicate
• An internet service that translates alphabetic names into IP addresses

What is meant by hosting? (3-6)

• A service that allows individuals and organisations to make their website available onthe world wide web
• A service that creates websites for companies
• A service that transmits data in a network
• A service that translates alphabetic names into IP addresses

What is cloud computing? (1-4)

• Storing large amounts of data on a single computer
• Using the internet to store and access data and programs remotely
• Storing hard copies of data as a backup
• Using the internet to communicate with other users

What problem can occur through using cloud computing? (3-6)

• There can be privacy and security issues
• More hardware needs to be added to a company network to store data
• Only a small amount of data can be stored
• Only a small amount of software can be stored

Which of these is a benefit of cloud computing? (3-6)

• It can reduce costs for a company as they do not need to buy additional hardware tostore data
• It is the cheapest option for a company to store their data as they do not need to pay forcloud computing
• Data can be accessed anywhere as an internet connect is not needed to access dataand software stored in cloud computing
• Data will always be more secure in a cloud computing system
