Understanding Computer Networks WS1

A ______________ is a device that connects multiple computers in a network and broadcasts data to all connected devices.

______________ are more intelligent than hubs and can direct data only to the intended recipient.

A ______________ is responsible for connecting different networks and directing data between them.

A ______________ converts digital signals from a computer into analog signals that can be transmitted over telephone lines.

A ______________ allows devices to connect to a network wirelessly.

Which device is more secure and efficient in a busy network?

• Hub

• Switch

• Modem

• Router

Answer explanation

A switch is more secure and efficient in a busy network because it directs data only to the intended device, reducing collisions and improving performance, unlike a hub which broadcasts to all devices.

What is the primary function of a server in a network?

• To connect different networks

• To store and provide access to shared resources

• To broadcast data to all devices

• To convert digital signals to analog

Answer explanation

The primary function of a server in a network is to store and provide access to shared resources, such as files and applications, enabling multiple users to access and utilize these resources efficiently.

Which component is necessary for a computer to connect to a network?

• Wireless access point

• Router

• Network interface card

• Hub

Answer explanation

A Network Interface Card (NIC) is essential for a computer to connect to a network, as it provides the hardware interface for communication over the network. Other components like routers and hubs facilitate networking but are not required for connection.

What is a disadvantage of using a hub in a network?

• It's more expensive

• It's more difficult to set up

• It can slow down the network when busy

• It doesn't broadcast data

Answer explanation

Using a hub can slow down the network when busy because it broadcasts data to all connected devices, leading to potential collisions and reduced performance during high traffic.

Which device is used to connect a local network to the internet?

• Switch

• Hub

• Router

• Server

Answer explanation

A router is the device that connects a local network to the internet, directing data packets between the two. Switches and hubs connect devices within a local network, while servers provide resources but do not connect to the internet directly.
