1 GCSE (9 1) Unit 1.4 Wired and Wireless Networks MCQS The numbers after the question are an approximate estimation of relative difficulty, broadly based around the new GCSE Numbering System. Please note that these were produced before final guidance was released regarding levels of difficulty and as such should be used as a rough guide only. Question 1: What is a standalone computer? (1-4) A computer that is not connected to a network A computer that is being used as a server A computer that does not have any peripherals attached to it A computer that is used by only one person Question 2: Which of these is a characteristic of a LAN? (3-6) It covers a wide geographical area Computers are connected together using a leased line or a satellite Users can share files and peripherals Data can only be transmitted at a very slow rate Question 3: Which of these is a characteristic of a WAN? (3-6) It covers a small geographical area Normally has a lower bandwidth than a LAN It is contained within one building Users are not able to share files and peripherals Question 4: Which of these statements is true? (3-6) A client-server network has a central computer that provides services to the rest of the network A client-server network is cheap and easy to set up A client-server network cannot be used to share files Each computer on a client-server network is maintain separately Question 5: Where are you most likely to find a peer-to-per network? (1-4) In a large organisation In a home In a large office Across several offices in a company Question 6: Which of these is a benefit of a peer-to-peer network? (6-9) Antivirus scans can be run across all computers from one computer All software updates can be run across all computers from one computer All computers can be maintained from one computer Files and peripherals can be shared Question 7: Which of these is the correct definition of a router? (1-4) Forwards data packets along a network Corrects errors that are found in data packets A type of transmission media that provides the greatest bandwidth A server within a network 1 OCR 2016
2 MCQS Question 8: Which transmission media is capable of having a much higher bandwidth? (6-9) Coaxial Twisted pair cable Plastic Fibre optic Question 9: Which type of transmission media is the least expensive to manufacture? (6-9) Coaxial Twisted pair cable Plastic Fibre optic Question 10: Which of these components is internal to a computer and is required to connect the computer to a network? (1-4) Wireless Access Point Network Interface card Switch Hub 2 OCR 2016
3 MCQS Question 1: 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 Question 2: Which if these terms refers to the maximum rate at which data can be transferred? (1-4) Error detection Packet switching Bandwidth Transmission media Question 3: 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 Question 4: 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 Question 5: 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 Question 6: 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 Question 7: What is meant by hosting? (3-6) A service that allows individuals and organisations to make their website available on the 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 3 OCR 2016
4 MCQS Question 8: 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 Question 9: 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 Question 10: 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 to store data It is the cheapest option for a company to store their data as they do not need to pay for cloud computing Data can be accessed anywhere as an internet connect is not needed to access data and software stored in cloud computing Data will always be more secure in a cloud computing system 4 OCR 2016
