18 Questions
What is the primary function of the demultiplexing field in a packet header?
To identify the right module for the next layer
Which of the following is a characteristic of the TCP/IP model?
It is less rigid and flexible than OSI
What is the purpose of the network layer in the TCP/IP model?
To route packets between networks
What is the primary difference between TCP and UDP protocols?
TCP is connection-oriented, UDP is connectionless
What is the function of a repeater or hub in a network?
To amplify or regenerate network signals
What is the purpose of multiplexing in network communication?
To allow multiple applications to share the same connection
What is the primary goal of layering in network functionality?
To provide a modular approach to implementing network functionality
What is a protocol in the context of network communication?
An abstract object or module in a layered structure that implements an agreement between parties on how communication should take place
What is a key advantage of using protocols in network communication?
Protocols allow for reuse and avoid re-writing of code
Why are protocols necessary for interoperability in networks?
Because networks are very heterogeneous and use different hardware and software
What is an example of layering in network communication?
The modular approach to implementing network functionality using multiple levels of abstraction
What is a key challenge in implementing layering in network communication?
Determining the right abstractions to use
What is the primary purpose of protocols in a network?
To provide a standardized way of communication
What is the primary function of the Network layer in the OSI model?
To route packets in a packet-switched network
What is the relationship between higher-level protocols and lower-level layers?
Higher-level protocols can run on multiple lower-level layers
What is the primary advantage of breaking down network functionality into layers?
To allow for easier modification and implementation of individual layers
What is the primary purpose of the OSI model?
To provide a reference model for ease of thinking and implementation
What type of communication is enabled by protocols and layers?
Both horizontal and vertical communication
Compare and contrast the OSI model with the TCP/IP standard. Learn about the different layers and their functions in computer networking.
