Question 1

The data link layer functions as a
A)pathway for multiplexing of data streams, data frame detection,
B)medium access control (mac) and error control.
C)data frame detection, medium access control
D)both a and b

Accepted Answer

The data link layer is responsible for multiplexing of data streams, data frame detection, medium access control (MAC), and error control, which are functions mentioned in both options A and B.

Question 2

Very limited resources for WSN refers
A)limited memory, and limited computation
B)limited power, and limited computation
C)limited memory, limited power,
D)limited memory, limited computation and limited power

Accepted Answer

Wireless Sensor Networks (WSNs) typically have constraints in memory, computation, and power, making option D the most comprehensive choice.

Question 3

Wireless networks are classified as:
A)infrastructure-based networks
B)ad-hoc network
C)infrastructure-based networks and infrastructure-less (ad-hoc) networks.
D)structured network

Accepted Answer

Wireless networks can be classified into infrastructure-based networks, where devices communicate through fixed points such as routers and access points, and infrastructure-less (ad-hoc) networks, where devices communicate directly with each other without relying on a fixed infrastructure.

Question 4

Infrastructure-based networks example is
A)wlan
B)manet
C)wlan and manet both
D)none of the above

Accepted Answer

Infrastructure-based networks rely on fixed structures like routers and access points to manage network traffic. WLAN (Wireless Local Area Network) is an example of this, as it typically requires a router or access point to connect devices. MANET (Mobile Ad-hoc Network), on the other hand, does not rely on a fixed infrastructure; instead, nodes communicate directly with each other.

Question 5

Infrastructure-less or Ad Hoc network, example is
A)wlan
B)manet
C)wlan and manet both
D)none of the above

Accepted Answer

MANET (Mobile Ad Hoc Network) is an example of an infrastructure-less or ad hoc network, where each node participates in routing by forwarding data for other nodes, and the network does not rely on a pre-existing infrastructure such as routers in wired networks or access points in managed (infrastructure) wireless networks.
