2.1 Networks Including the Internet Cambridge iAS 9618

What is a key benefit of networking devices?

• They allow multiple devices to communicate and share resources

• They increase the storage capacity of individual devices

• They eliminate the need for security measures

• They make wired networks obsolete

What is a key difference between a LAN and a WAN?

• A LAN covers a small geographical area, while a WAN spans large distances

• A LAN requires internet access, while a WAN does not

• A WAN uses only wireless connections, while a LAN uses only wired connections

• A LAN is slower than a WAN

Which network model relies on a central server to manage resources?

• Client-server

• Peer-to-peer

• Mesh network

• Hybrid network

What is a characteristic of a peer-to-peer network?

• Each computer can act as both a client and a server

• All files are stored on a central server

• Only one device can connect at a time

• It requires a dedicated router

What is an advantage of a thin-client model?

• It requires less powerful hardware on the client side

• It allows users to run programs locally without a server

• It requires no network connection to function

• It increases local storage requirements

Which network topology uses a central switch to connect all devices?

• Star

• Bus

• Mesh

• Ring

What is a key advantage of a mesh topology?

• It provides redundancy and fault tolerance

• It is cheaper to implement than other topologies

• It requires fewer connections than a bus topology

• It is the simplest topology to set up

What is a drawback of cloud computing?

• Data security concerns due to third-party storage

• The inability to access files remotely

• It requires constant software updates on user devices

• It cannot store multimedia files

What is a key advantage of a wired network over a wireless network?

• It is typically faster and more secure

• It is cheaper to set up

• It allows devices to connect from anywhere without cables

• It requires no additional hardware

Which transmission medium uses light signals to transmit data?

• Fibre-optic cable

• Copper cable

• Radio waves

• Microwaves
