Introduction to Computer Networks

Which of the following is a common type of network?

• Local area network (LAN)

• Bluetooth network

• Satellite network

• Infrared network

What is one benefit of centrally storing company files and templates on a LAN?

• All company documentation has the same style, layout, and appearance.

• Employees can only access files from their home computers.

• Files are automatically deleted after one week.

• Only managers can view the files.

Why are Ethernet and Wi-Fi important in the context of LANs and WANs?

• They are standard technologies for network communication.

• They are used for video streaming only.

• They are used for connecting printers only.

• They are used for mobile phone communication only.

Why can LANs be more susceptible to security threats?

• They use wireless connections only.

• They are easier to spread viruses and are more susceptible to security threats.

• They are always connected to the internet.

• They do not require passwords.

How does reliance on centralized hardware affect LANs?

• It makes LANs more reliable.

• It makes LANs prone to failure if central components fail.

• It reduces the need for maintenance.

• It increases the physical range of LANs.

Which of the following best describes the primary use of a Wide Area Network (WAN)?

• Connecting devices within a single building

• Connecting devices over a large geographical area, such as several countries

• Connecting devices within a local neighborhood

• Connecting devices only within a city

Why do businesses, organisations, educational establishments, and governments use WANs?

• To exchange data between computers in their remote offices around the world

• To play online games

• To print documents locally

• To connect only within a single city

If you were to design a network that includes both clients and servers, which network model would you be using?

• Client-server network

• Peer-to-peer network

• Wireless network

• Mesh network

In a client-server network, how are other computers typically connected?

• All other computers are connected to the server to allow it to perform its dedicated function.

• Computers are connected randomly without any central server.

• Each computer is only connected to one other computer.

• Computers are not connected to any server.

A business wants to host several websites but only has one physical server. What solution can they use, and why is it effective?

• They can use virtual servers, which allow multiple websites to be hosted on the hardware of a single physical server.

• They must purchase multiple physical servers for each website.

• They should use only one website per server for security reasons.

• They cannot host multiple websites with one server.
