Question 1
1.
What is a data packet?
A) A complete file sent over the internet in one piece
B) A fixed-length block of data used only in local networks
C) A small unit of data that is part of a larger message, sent separately over a network
D) A special signal used to check network connectivity
Question 2
2.
Why does the internet use packet switching instead of circuit switching?
A) Packet switching is more reliable and allows multiple devices to share the network efficiently
B) Circuit switching is too expensive to implement
C) Packet switching requires less data to be transmitted
D) Circuit switching does not allow error detection
Question 3
3.
What information does a data packet contain?
A) Only the raw data being sent
B) Source and destination addresses, sequence number, error-checking information, and payload
C) The sender's username and password
D) Only the destination address
Question 4
4.
Which best describes how packets are routed on the internet?
Sent directly without routing by devices.
Packets float randomly until reaching destination.
All packets follow the same path always.
Using routers to determine optimal paths based on addresses.
Question 5
5.
What happens when a data packet gets lost?
Data remains incomplete, no retransmission occurs.
The network ignores the loss permanently.
It is retransmitted based on protocol rules.
Lost packets are not detected at all.
Question 6
6.
What is the role of TCP in data packets?
Routes packets based on the destination IP.
Ensures packets are sent reliably and in order.
Encrypts packets for security before sending.
Converts packets to video for streaming.
Question 7
7.
Which statement defines a packet in networking?
A single address in a web request.
A complete file ready for downloading.
A small unit of data formatted for transmission.
A continuous stream of unformatted data.
Question 8
8.
What happens if some packets arrive out of order?
A) The data is lost and must be resent
B) The receiving computer discards all packets and requests a new transmission
C) The receiving device reassembles them using sequence numbers
D) The packets automatically rearrange themselves during transmission
Question 9
9.
Which protocol is responsible for ensuring that all packets arrive correctly and in order?
A) HTTP
B) TCP (Transmission Control Protocol)
C) FTP
D) IP (Internet Protocol)
Question 10
10.
What happens when a data packet is lost?
Data is corrupted and cannot be recovered.
The transmission stops completely until resolved.
All packets are dropped forever during transmission.
The packet is retransmitted if acknowledgment is not received.
Question 11
11.
How does a system know a packet is lost?
All packets must arrive in a specific order.
The packet's data appears empty or invalid afterwards.
It doesn't receive an acknowledgment within a set time.
It's notified by the sending device automatically.
Question 12
12.
What can cause packet loss in networks?
Network congestion or hardware failure during transmission errors.
Specifically when sending video files only.
Too many devices connected at once.
By using slow internet connections only.
Question 13
13.
What protocol helps in resending lost packets?
FTP only retrieves files.
TCP (Transmission Control Protocol) manages reliable data transmission.
HTTP runs website connections.
UDP ensures no packets are lost.
Question 14
14.
What is a primary advantage of packet switching?
More reliable than circuit switching.
Efficient use of network resources and bandwidth.
Every call gets exclusive channel access.
Improved call quality for all users.
Question 15
15.
How does packet switching handle network congestion?
Allocates a fixed bandwidth to each call.
Packets can reroute dynamically based on traffic conditions.
It blocks all new connections temporarily.
Sends data sequentially without rerouting.
Question 16
16.
Why is packet switching preferred for Internet data?
It is slower than traditional circuit switching.
It uses fixed paths for all data transmission.
It allows multiple transmissions over the same lines simultaneously.
It guarantees delivery speed for all packets.
Question 17
17.
Which situation illustrates packet switching effectively?
Sending a video while browsing a website.
A dedicated phone call over a network.
Streaming music with no interruptions guaranteed.
Transferring files with a fixed route.
Question 18
18.
What are the connected steps between a sending and a receiving location called?
A route
A heuristic
A path
A conduit
