1. In the con1. Which of the following layers is responsible for routing
packets across different networks?
A. Physical Layer
B. Data Link Layer
C. Network Layer
D. Transport Layer
Answer: C) Network Layer
Rationale: The Network Layer is responsible for routing packets across
different networks, ensuring that data reaches its destination even if it
has to pass through multiple routers.
2. What does the term 'latency' refer to in networking?
A. The speed at which data is transmitted
B. The time delay between the sending and receiving of data
C. The maximum number of devices in a network
,D. The capacity of a network to carry data
Answer: B) The time delay between the sending and receiving of data
Rationale: Latency refers to the delay between sending and receiving
data, often measured in milliseconds (ms).
3. Which of the following devices connects different networks and
forwards packets based on IP addresses?
A. Hub
B. Router
C. Switch
D. Bridge
Answer: B) Router
Rationale: A router connects different networks and forwards packets
based on IP addresses.
4. What is the main characteristic of the OSI reference model?
A. It defines the hardware components of a network
,B. It specifies the implementation of protocols
C. It divides network communication into seven layers
D. It determines the physical topology of the network
Answer: C) It divides network communication into seven layers
Rationale: The OSI model divides network communication into seven
distinct layers, each with specific functions.
5. Which type of reactor is most commonly used for microbial
production of antibiotics?
A. Plug-flow reactor
B. Batch reactor
C. Continuous stirred-tank reactor (CSTR)
D. Air-lift reactor
Answer: B) Batch reactor
Rationale: Antibiotics are typically produced in batch reactors, where
the culture is allowed to grow and produce the product over a defined
period.
, 6. What is the main characteristic of a circuit-switched network?
A. Data is divided into packets and transmitted independently
B. A dedicated communication path is established for the duration of
the session
C. Data transmission is unreliable
D. The network is based on a mesh topology
Answer: B) A dedicated communication path is established for the
duration of the session
Rationale: In circuit-switched networks, a dedicated path is reserved for
the entire duration of the communication session.
7. Which of the following is used in a wireless LAN to communicate
between devices?
A. Microwave signals
B. Radio waves
C. Optical fibers
packets across different networks?
