What is a LAN (Local area network)?

• A network that connects computers over a large geographical area.

• A network that connects computers over a small geographical area such as a single building or a single site

• A network that uses external hardware and external infrastructure such as a satellite and phone lines

• A global collection of networks

Which of the following is a characteristic of a WAN ( Wide area network)?

• It connects computers within a home network.

• It uses a central server to connect all clients

• It covers a large geographical area, possibly countrywide or even worldwide

• It does not require any external hardware or infrastructure

What is the main role of a router in a network?

• To connect a LAN to another LAN.

• TO send data to specific users connected to a wired network

• To move data from one network to another

• To store all files centrally on a client-server network.

What is the function of a switch in a network?

• It allows wireless devices to connect to a network

• It sends data to specific users, increasing the security of the network.

• It connects a network card to a MAC address

• It reduces traffic on the network by segmenting it.

What is the primary difference between a client-server and a peer-to-peer network?

• In a client-server network, all files are stored on a central server, whereas in a peer-to-peer network all files are stored on their own computers.

• A client-server network requires additional hardware, while a peer-to-peer network does not.

• A client-server network is suitable for high traffic environments, while a peer-to-peer network is not.

• A client-server network is less secure than a peer-to-peer network.

Which of the following is true about a bridge in a network?

• It is used to connect a computer to a wireless network

• It is used to connect a LAN to another LAN

• It is a device that stores files centrally on a client-server network

• It is a protocol used for wireless transmission using radio signals

What is the main purpose of a DNS server?

• To host websites

• To connect different network topologies

• To translate domain names into IP addresses

• To store data in the cloud

Which network topology has one central node connected to all other nodes

• Bus

• Ring

• Star

• Mesh

What is the function of a protocol in a network

• To register domain names

• To ensure data security

• To determine the method of data exchange

• To connect to the central node in a star topology

What is the benefit of the cloud

• To provide a central node for network topologies

• To increase storage and access files from anywhere

• To translate domain names into IP addresses

• To reflect signals in a bus network
