Which of the following correctly describes the types of network topologies and their characteristics?
In computer networks, what is the difference between a LAN, MAN, and WAN in terms of geographic scope and typical technology used?
Which layer converts data into signals suitable for transmission over a physical medium?
A packet of 1000 bytes is sent over a link with bandwidth 1 Mbps and propagation delay 20 ms. What is the total time to send the packet from sender to receiver (transmission delay + propagation delay)?
In encapsulation, data flows from upper layers to lower layers. Which of the following shows the correct order of headers added?
What is the PDU (Protocol Data Unit) at the Data Link Layer called?
Which of the following correctly identify key differences between the OSI model and the TCP/IP model?
Shannon's theorem (Shannon-Hartley theorem) gives the maximum theoretical data rate of a noisy channel. The formula is C = B × log₂(1 + S/N), where C is channel capacity, B is bandwidth, and S/N is the signal-to-noise ratio. If a channel has bandwidth B = 3 MHz and S/N ratio = 15, what is the maximum channel capacity?
A host wants to send data to another host on a different network. As the data travels from source to destination through intermediate routers, which layers' headers are read and modified by each router?
Which of the following correctly describes the difference between connection-oriented and connectionless communication at the Transport Layer?
In network communication, what is the difference between latency (delay) and bandwidth?
The TCP/IP model does NOT have a separate layer corresponding to the OSI model's:
The TCP/IP model has how many layers, and how do they map to the OSI model?
Which layer of the OSI model handles the representation, encryption, and compression of data?
Which of the following network devices operate at the specified OSI layers?
Which of the following correctly describes the role of the Network Layer in the OSI model?
In a network, the concept of 'bandwidth' at the physical layer and 'throughput' at higher layers are related but different. Which of the following correctly distinguishes them?
The Physical Layer of the OSI model is responsible for which of the following?
The OSI (Open Systems Interconnection) reference model divides network communication into how many layers, and which layer is responsible for end-to-end reliable data delivery?
In the OSI model, which layer is responsible for data compression, encryption, and format conversion (e.g., converting between ASCII and EBCDIC)?
