Q1Assertion (A): In a star topology, all computers are usually connected to a central device such as a hub or switch. Reason (R): The central device helps pass data between the connected computers.
In star topology, each computer or node is connected to a central device, commonly a hub or switch. That makes the assertion true. The reason is also true because this central device helps pass data between the connected computers. More importantly, the reason explains the assertion: the central device is not just present physically; it is the communication point through which connected devices exchange data. Therefore, both A and R are true, and R correctly explains A.
Q2In a school computer lab, all computers are connected within one building so that students can share a printer and files. Which type of network is this?
A Local Area Network, or LAN, connects computers within a limited area such as a room, office, school lab or one building. The key cue in the stem is that all computers are inside one building and are sharing local resources like a printer and files. A WAN is used when the area is much larger, for example across cities or countries. The Internet is global. Therefore, the lab arrangement described here is a LAN.
Q3Match List I with List II. List I: I. HTTP II. IP address III. URL IV. Web browser List II: 1. Address of a web resource 2. Protocol used for transferring web pages 3. Software used to access websites 4. Address that identifies a device on a network
HTTP is the protocol used for transferring web pages, so I matches 2. An IP address identifies a device on a network, so II matches 4. A URL is the address of a web resource, so III matches 1. A web browser is the software used to access and view websites, so IV matches 3. The complete matching is I-2, II-4, III-1, IV-3. This question checks the difference between a protocol, an address, and application software.
Q4Which of the following statements about an IP address is incorrect?
An IP address is used to identify a device on a network so that data can reach the correct destination. In IPv4, it is commonly written as numbers separated by dots. The question asks for the incorrect statement. Devices on the same network cannot all have exactly the same IP address, because that would create an address conflict and make delivery unclear. Therefore, the statement that every device has the same IP address is the incorrect one.
Q5Which one of the following statements about common networking terms is incorrect?
The question asks for the incorrect statement. An IP address is used to identify a device on a network, so option A is correct as a fact. Wi-Fi commonly provides wireless network access through radio waves, and Ethernet is a standard wired LAN technology, so B and C are also correct facts. Bluetooth, however, is meant for short-range personal-area communication, such as connecting a phone with earphones, a keyboard or another nearby device. It is not designed for countrywide long-distance networking. Therefore, D is the incorrect statement.

6Match List I with List II. List I: I. Modem II. Switch III. Router IV. Network Interface Card List II: 1. Connects devices mainly within a LAN 2. Connects different networks 3. Converts digital signals for transmission over communication lines 4. Provides a computer with a network connection interface
7Which network device is mainly used to connect different networks and forward data packets towards their destination?
8Consider the following statements about web communication. Statement 1: HTTP is a protocol used for transferring web pages between a web server and a browser. Statement 2: HTTPS is a more secure form of HTTP because it uses encryption for communication. Which of the statements is/are correct?
9Which device is mainly used to connect two or more different networks and forward data packets between them?
10Statement I: An IP address helps identify a device on a network. Statement II: Every IP address is used only for printing documents. Which option is correct?
11Assertion (A): In a LAN, a switch usually reduces unnecessary data traffic compared with a hub. Reason (R): A switch can forward data towards the intended destination port instead of sending it to every port.
12Read the Assertion (A) and Reason (R), then choose the correct option. Assertion (A): A website URL beginning with HTTPS is generally safer for entering passwords than the same site over HTTP. Reason (R): HTTPS encrypts the data exchanged between the browser and the web server.
13Which statement correctly describes a LAN in basic computer networking?
14Match the network device with its usual function. List I: I. Modem II. Router III. Switch IV. Repeater List II: 1. Regenerates a weak network signal 2. Connects different networks and forwards data between them 3. Converts digital signals and telephone/cable-line signals 4. Connects devices inside a local network efficiently
