- Q1What is a computer network?A collection of computers that all have access to the internetTwo or more computers, that have been connected together and that can communicate with one another.A computer that is connected to the internetComputers that are in the same room or office30s3.5.1
- Q2What is the role of a file server in a network?Sorts users files according to sizeStops users from accessing file on the networkAllows users access to the internetHolds network users files and allows those in the network access to these30s3.5.1
- Q3What is the risk of a file server breaking down?Files will be deletedFiles can still be access but only via the internetIt is costly to fixFiles contained on it become inaccessible30s3.5.1
- Q4Which network configuration is where all computers connect to the network via a central 'backbone' cable?Bus TopologyNeitherStar TopologyBoth30s3.5.1
- Q5Which network configuration has a one central computer that has each computer or network device attached to it?NeitherBus TopologyStar TopologyBoth30s3.5.1
- Q6Which of these is an advantage of the Star Topology?It does not require any additional hardware to set upThey are very cheap to cable compared to other structuresIf the central device fails then they can continue to work independentlyThey are reliable as if one cable or device fails then the other devices will be unaffected30s3.5.1
- Q7Which of these is a disadvantage of the Star Topology?Data collisions occur as you add more devices to the networkIt is not reliable as if one device fails, they all failIf the central device fails, then so will the whole network.It can be harder to manage security risks30s
- Q8Which of these is an advantage of the Bus Topology?There are no data collisionsIt is less at risk of security hacksIt is easy and cheap to install as a consequence of requiring only a small quantity of cable.Traffic does not reduce in speed as more computers are added30s3.5.1
- Q9Which of these is a disadvantage of the Bus Topology?It has most risk of data collisions as more computers are added to the networkAll of theseif the main cable fails or gets damaged the whole network will failAll workstations see all data - so there is a security risk.30s3.5.1
- Q10What is one disadvantage of using a network?You need all computers to have the same softwareIt is inefficient for sharing resources across larger sitesYou are more vulnerable to security risks such as hacking and virusesYou can only used a network when computers are in the same geographical location30s3.5.1
- Q11What is an alternative to using cabled network systems, that has grown in popularity in recent years?Not using networks at allUsing a cloud based networkAsking people to use their own devicesSaving everything onto portables Hard Drives30s3.5.1
- Q12What is one advantage to using a network?All of theseYou can share peripherals such as printers with multiple machinesIt is easier to communicate across larger geographical areasIt is much easier to share resources30s3.5.1
