Multiple Choice

What is a computer network?

• A computer network is a collection of unrelated devices.
• Two or more computers connected to share resources

• A computer network is a single computer with multiple users.
• A computer network is a type of software application.

Multiple Choice

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

• To connect devices within a LAN

• To connect different networks and manage internet access

• To store data for all computers in the network

• To provide power to network devices

Multiple Choice

What is the Concept of Layer?

• A layer is a type of software that only runs on mobile devices.
• A layer is a single point in a network that does not serve any function.
• A layer is a physical object that cannot interact with other layers.
• A layer is a distinct level within a system that serves a specific function and interacts with other layers.

Multiple Choice

Which of the following tasks is NOT mentioned as a responsibility of software in networking?

• Handling tasks without knowing about other software in higher or lower layers

• Encrypting all data packets

• Routing traffic using IP

• Sending web pages using HTTPS

Multiple Choice

What happens to a packet when it reaches a router according to the TCP-IP model?

• 
  The router adds an application layer header

• The router converts the packet into a frame

• 
  The router immediately sends the packet to its final destination

• The router strips off the outer layer and passes it up to the network layer

Multiple Choice

What is the significance of the TCP-IP protocol stack?

• It is a single protocol that cannot be divided

• 
  It is only used for local area networks

• It is outdated and no longer in use

• 
  It allows any device to communicate and transfer data across the internet

Multiple Choice

Why are packets numbered in the transport layer?

• 
  To identify the type of application used

• 
  To ensure packets can be reassembled in the correct order

• To increase the speed of data transfer

• To make encryption easier

Multiple Choice

What does the network (internet) layer add to each packet?

• 
  A source and destination MAC address

• A source and destination IP address

• The total number of packets and a port number

• 
  An application protocol header

Multiple Choice

What is the role of the transport layer in the TCP-IP protocol stack?

• To handle the physical connection between nodes

• To decide the final destination of the packet

• To add a source and destination IP address to each packet

• 
  To establish an end-to-end connection and split data into packets

Multiple Choice

Which method is mentioned as a way to transfer data between devices?

• Using peer-to-peer and client-server methods

• Using a single type of cable for all data transfer

• Only using wireless methods

• Transferring data without splitting into packets

Multiple Choice

What is the primary purpose of dividing networking into layers?

• To limit the number of devices on a network.
• To simplify design and implementation of network protocols.
• To ensure all devices use the same hardware.
• To increase the complexity of network protocols.

Multiple Choice

What is the purpose of using different types of cables and wireless methods in networking?

• To accommodate different data transmission needs and environments

• To ensure data can only be sent in one direction

• To complicate the networking setup process

• To limit the speed of data transfer
