Routing in OSI Network Architecture

Answer: B. Data link layer

Explanation:

The OSI (Open Systems Interconnection) model is a conceptual framework that standardizes the functions of a communication system into seven different layers. The routing process, which involves the selection of the best path for data packets to travel from the source to the destination, is primarily performed by the network layer in the OSI model. However, the data link layer also plays a role in routing by facilitating the transmission of data between directly connected nodes or devices. Here's a breakdown of the routing process in the OSI model:

1. Network Layer:

• The network layer is responsible for logical addressing, routing, and path determination.


• It receives data from the transport layer and adds network layer headers to create packets.


• It determines the best path for packet transmission based on the destination address and network conditions.


• It uses routing protocols (such as OSPF, RIP, BGP) to exchange routing information and build routing tables.


• It forwards packets to the next hop or the next network based on the routing table.

2. Data Link Layer:

• The data link layer provides reliable point-to-point communication between directly connected nodes.


• It encapsulates the network layer packets into data frames and adds data link layer headers and trailers.


• It performs error detection and correction using techniques like CRC (Cyclic Redundancy Check).


• It controls the flow of data between devices to avoid congestion.


• It uses MAC (Media Access Control) addresses to identify devices on the same network.


• It performs local network routing by forwarding data frames to the appropriate device based on MAC addresses.

While the primary responsibility of routing lies with the network layer, the data link layer contributes to the routing process by facilitating communication between directly connected devices. Therefore, in the OSI network architecture, routing is performed by both the network layer and the data link layer.

Print Chart:

• A: Refers to a printed chart.


• B: Indicates a chart that is filled in by an analyst while formatting a report.


• C: Describes a chart that is prepared by users.


• D: States that the chart is printed by a computer.

The correct answer is B, as it specifically mentions that the chart is filled in by an analyst while formatting a report. Let's further explain each option:
A: A printed chart: This option refers to a chart that has been physically printed, but it does not specify who prepares or fills in the chart.
B: One which is filled in by an analyst while formatting a report: This option explicitly states that the chart is filled in by an analyst during the process of formatting a report. This suggests that the chart is part of the report and is completed by an analyst with the necessary data.
C: Prepared by users: This option indicates that the chart is prepared by users, but it does not mention who these users are or how the chart is used in the context of a report or formatting.
D: Printed by computer: This option suggests that the chart is printed by a computer, but it does not provide any information about who creates or fills in the chart.
In conclusion, the correct option is B as it clearly specifies that the chart is filled in by an analyst while formatting a report.

Software:
- Software refers to a collection of programs, data, and instructions that enable a computer system to perform specific tasks or functions.
- It is a set of instructions that tells the computer what to do and how to do it.
- It can be categorized into system software and application software.
Option B: Firewalls
- Firewalls are software programs or applications that monitor and control incoming and outgoing network traffic based on predetermined security rules.
- They act as a barrier between a trusted internal network and an untrusted external network, providing protection against unauthorized access and threats.
- Firewalls can be installed on individual computers or network devices such as routers or dedicated firewall appliances.
Explanation:
- Among the given options, firewalls are the software that is used to protect computer networks from unauthorized access and threats.
- Routers (Option A), gateways (Option C), and modems (Option D) are hardware devices that are used for network connectivity and data transmission, but they do not fall under the category of software.
- Firewalls, on the other hand, are software programs that are installed on computers or network devices to provide security and control over network traffic.
- Therefore, the correct answer is Option B: Firewalls.

Telnet is a Remote Login Protocol
Telnet is a protocol that allows users to remotely log in to another computer or server over a network. It provides a virtual terminal connection, allowing users to access and interact with the remote system as if they were physically present. Here are some key points to understand about Telnet:
1. Definition:
- Telnet is a network protocol used to establish a remote login session between a local client and a remote server.
- It allows users to access and control the functions of a remote computer or server over a network.
2. Functionality:
- Telnet enables users to log in to a remote system and perform various tasks and operations.
- It provides a command-line interface to interact with the remote system's operating system and execute commands.
3. Client-Server Model:
- Telnet follows a client-server model, where the local client initiates a connection request to the remote server.
- The server listens for incoming Telnet connections on a specific port (default port 23) and responds to client requests.
4. Terminal Emulation:
- Telnet provides terminal emulation, allowing the local client to access the remote system's command-line interface.
- It emulates a terminal or console on the local machine, providing a text-based interface to interact with the remote server.
5. Security Concerns:
- Telnet transmits data, including login credentials, in plain text format, making it vulnerable to eavesdropping and data interception.
- Due to its lack of encryption, Telnet is considered insecure, and its usage is discouraged in favor of more secure protocols like SSH (Secure Shell).
In conclusion, Telnet is a remote login protocol that allows users to establish a virtual terminal connection with a remote computer or server over a network. It provides a command-line interface for executing commands and accessing the remote system's functions. However, its lack of encryption makes it insecure for transmitting sensitive information, and alternative protocols like SSH are recommended for secure remote access.

Representation of Digital Signals:

• Binary Codes: Digital signals can be represented using binary codes, which are sequences of 0s and 1s.


• 0 and 1: Another common representation of digital signals is using the binary digits 0 and 1.


• High and Low: Digital signals can also be represented using the concepts of "high" and "low" voltage levels. A high voltage level represents a logical 1, while a low voltage level represents a logical 0.


• All of the Above: The correct answer is option D, as digital signals can be represented using binary codes, 0 and 1, as well as high and low voltage levels.

By utilizing these various representations, digital signals can be transmitted, stored, and processed in digital systems. The choice of representation depends on the specific application and the requirements of the system.

Answer:
The time taken by internet packets can vary depending on various factors. Let's explore these factors in detail:
1. Network Congestion:
- Internet traffic and congestion can affect the time taken by packets to reach their destination.
- During peak hours or in heavily congested networks, packets may experience delays.
2. Packet Size:
- The size of the packet can also impact the time taken.
- Larger packets may take longer to transmit compared to smaller packets.
3. Routing:
- The route the packets take from the source to the destination can also affect the time taken.
- Different routing paths may have varying latencies, causing differences in packet delivery time.
4. Network Quality:
- The quality and stability of the network infrastructure can impact packet delivery time.
- Unstable or unreliable networks may result in packet loss or increased latency.
5. Packet Priority:
- Certain packets, such as real-time audio or video packets, may be given higher priority and transmitted faster.
- However, this does not mean that the time taken by packets is irrelevant for audio packets.
In conclusion, the time taken by internet packets can vary based on network congestion, packet size, routing, network quality, and packet priority. Therefore, option B is the correct answer, while option C is incorrect as the time taken is relevant for all types of packets, including audio packets.

The given passage states that the WHO and UNICEF are engaged in a number of programmes in cooperation with the Government of India.

3D definition- A three-dimensional (3D) object is an object with three dimensions: a length, a width, and a height
Since solid figure has length breadth as well as thickness or height so sthe solid figure will be 3d. hence option B is correct.

Area of Trapezium  = 1/2 (sum of Parallel sides ) * height
let a and b are the parallel sides:
a= 4cm
b= 6 cm
h= 3cm
according to formula -> 1/2(4+6)*(3)
=>1/2(10)(3)
=>30/2
=>15 cm²

As per question, we have,
p = ab² = a × b × b
q = a³b = a × a × a × b
So, their Least Common Multiple (LCM) = a³ × b²

So the answer = 30 × 63 = 1890 meters
Hence, Option D is correct.

The real numbers consist of both rational and irrational numbers. so the other three options are not true as the first one is not true because not only every real number is a rational number but the real number is rational and irrational both. same goes for the second one and the last option is not true because one half and the other half can be irrational or rational both.

Using Rule 1 :
1st number × 2nd number = L.C. M. × H.C.F,
First number × Second number = HCF × LCM
⇒ 864 × Second number
= 96 × 1296 ⇒ Second number

The A.P. is -3, -1/2, 2 …
Where a = – 3
d = a(2) – a(1) = (-1 / 2) - (-3)
⇒ (-1 / 2) + 3 = 5 / 2
a(n) = a + (n−1) x d
a(11) = 3 + (11-1) x (5 / 2)
a(11) = 3 + (10) x (5 / 2)
a(11) = -3 + 25
a(11) = 22

Combined weight of the group increases by = 2 × 15 = 30 kg
So the answer = 40 + 30 = 70 kg
Hence, Option C is correct.

The sequence is a combination of two series:

I. 19, 38, 114, (____)
II. 2, 3, 4

Considering Series I:
1st term = 19
2nd term = 19*2 = 38
3rd term = 38*3 = 114
Thus, the missing number is 4th term = 114 * 4 = 456

Let X and Y be two buses. Bus X travels the PA, AB, BC, CD.
Now, AD = BC = 25 km.
So, PD = PA +AD = 50km.
Bus Y travels 35km upto E.
Distance between two buses = PQ – (PD + QE)
= [150 – (50 + 35)] = 65 km.

The logic followed is:

ROSE is coded as 6821

CHAIR is coded as 73456

PREACH is coded as 961473

Therefore SEARCH will be written as

Hence, the correct answer is "214673".

Given:

(a + b) : (b + c) : (c + a) = 6 : 7 : 8

a + b + c = 14

Calculaiton:

(a + b) = 6k

(b + c) = 7k

(c + a) = 8k

⇒ 2(a + b + c) = 21k

⇒ 21k = 2 × 14

⇒ 21k = 28

⇒ k = 4/3

⇒ c + a = 8 × 4/3

⇒ c + a = 32/3

As given,

⇒ b + 32/3 = 14

⇒ 3b + 32 = 42

⇒ 3b = 10

∴ b = 10/3

All except Seal are creatures related to signs of zodiac.

The pattern followed is:

Hence, the correct answer is "110".

Gita is sister-in-law of Bhanu means Bhanu is the brother of Gita’s husband.
But Bhanu has only one brother, Sanjay.
Sanjay is Gita’s husband.
Rita is mother-in-law of Gita means Rita is the mother of Sanjay.
So, Rita is Bhanu’s mother.
