Surinsar Mansar Wildlife Sanctuary is located 58 km away from the Jammu city. It spread over an area of 98 square km. There are two lakes Surinsar and Mansar. This sanctuary has got its name from these lakes. It was established in 1981.

The village and community lands are used to develop the tree crops and fodder species with the help of local people.

Jammu and Kashmir has only 30% of the reporting area under cultivation yet agriculture supports around 70% of the population. The cold desert region of Ladakh gives little scope of cultivation. However, the climatic diversity from sub-tropical to temperate to cold provides a variety of crops, fruits, vegetables and flowers to these regions.

Goat rearing is done on the pastoral meadows of Kashmir valley. Changra or Pasham goats are mainly reared for Pashmina wool which is very soft and fine wool.

In order to attract substantial investment in the state's industries and generate huge employment by utilising the available resources, the Jammu and Kashmir Government has launched the New Industrial Policy in March, 2016. It aims to promote industries within a duration of ten years i.e. from 2016 to 2026. The Government has divided the districts into two zones depending upon the level of industrial development.

Additional Information

• The word computer is derived from the word compute. In the year 1833, English mechanical engineer Charles Babbage designed the first analytical engine. He is known as the father of the computer.
• In the beginning, computers are used for calculating large numbers and can only store a small amount of data.
• The software and the hardware parts of the computers are running together to execute the operations smoothly.
• Software is a set of instructions or programs given to the computers' hardware to perform a task. For example, system software (OS), application software( MS Office, Browser), and programming software(compiler).
• The hardware parts of the computer are tangible parts of the computer which collect the input (e.g. keyboard, mouse, scanner etc.), and process (e.g. C.P.U). It and display it to the respective output devices(e.g. monitor, printer etc.). Sometimes it stores the processed data in the memory.

The correct answer is Second.

Key Points

• Second-generation computers (1955-1964) were made of transistors.
• The second generation of computers, which used transistors instead of vacuum tubes, were released in the late 1950s and early 1960s as interest in computer technology grew quickly.
• The second generation of computers, however, was entirely built using transistors rather than vacuum tubes.

Additional Information

Correct answer is Optical Mark Reader

Key Points 

• Optical mark recognition (OMR) is an electronic method of gathering human-handled data by identifying certain markings on a document.
• Usually the optical mark recognition process is achieved with the aid of a scanner that checks the transmission or reflection of light through the paper; places having markings will reflect less light than the blank paper, resulting in less contrasting reflectivity.
• Optical mark recognition is also known as optical mark reading or, more commonly, by the brand name Scantron.

Explanation:
The round robin CPU scheduling algorithm is a time-sharing system where each process is executed for a fixed time slice called a time quantum. Once the time quantum expires, the CPU is preempted and the next process in the queue is executed. This process continues until all processes have been executed.
Now, let's analyze the statements given in the question:
A: Using very large time slice degenerates into first come first serve algorithm
- When a large time slice is used, each process is allowed to run for a longer duration before being preempted.
- This essentially means that the CPU is allocated to each process in a sequential manner, following the order in which they arrived.
- Therefore, using a large time slice in round robin scheduling effectively degenerates into the first come first serve algorithm.
B: Using extremely small time slices improves performance
- Using extremely small time slices can lead to a high overhead due to the frequent context switches between processes.
- Context switching involves saving the current state of a process and loading the state of the next process, which incurs additional time.
- This overhead can degrade the overall system performance, especially when the number of processes is large.
C: Using extremely small time slices degenerates into last in first out algorithm
- This statement is not accurate. Using extremely small time slices does not lead to a last in first out algorithm.
- In round robin scheduling, the order of execution is based on the arrival time of the processes, not the order in which they were added to the queue.
D: Using medium-sized time slices leads to shortest request time first algorithm
- This statement is also not accurate. The round robin scheduling algorithm does not prioritize processes based on their request time.
- Instead, it ensures that each process gets an equal share of the CPU's time by using a fixed time slice.
Therefore, the correct answer is:
A: Using very large time slice degenerates into first come first serve algorithm

Answer:
802.5 is the correct answer because it provides for a collision-free protocol. Here's a detailed explanation:
802 Standards:
The 802 standards are a set of networking protocols defined by the Institute of Electrical and Electronics Engineers (IEEE). These standards define the specifications for various aspects of network communication, including data link layer protocols, physical layer specifications, and network management.
Collision:
In networking, a collision occurs when two or more devices on a network attempt to transmit data at the same time, resulting in a garbled signal. Collisions can cause data loss and network congestion, leading to decreased performance.
802.2:
- Also known as the Logical Link Control (LLC) standard.
- Defines the interface between the Media Access Control (MAC) sublayer and the network layer.
- It does not provide a collision-free protocol.
802.3:
- Also known as Ethernet.
- Defines the CSMA/CD (Carrier Sense Multiple Access with Collision Detection) protocol.
- CSMA/CD allows devices to detect collisions and handle them by retransmitting the data.
- It does not provide a collision-free protocol.
802.5:
- Also known as Token Ring.
- Defines a token passing protocol, where a token is passed between devices to control access to the network.
- Only the device holding the token can transmit data, ensuring a collision-free protocol.
- It provides a collision-free protocol.
802.6:
- Also known as Distributed Queue Dual Bus (DQDB).
- Defines a protocol for metropolitan area networks (MANs).
- It does not provide a collision-free protocol.
Therefore, the correct answer is 802.5 as it provides for a collision-free protocol.

According to question , we can see that
A, P, R, X, S and Z are sitting in a row.
S and Z are in the centre
and A and P are at the ends. R is sitting on the left of A.
Hence , X is sitting on the right of P .

In the morning shadow always falls in the west direction as the sun always rises in the east. So the sun is in the east in the morning and the shadow is in the west.

One morning Radha started walking and walked for 2km. She then takes a right turn and walks for another 3km. At that time her shadow was her right-hand means Radha started walking to the east side for 2km. Then takes a right turn means she is walking towards the south for 3km and her shadow is on the right-hand side means on the west side.

So, starting direction of Radha is east and her shadow is on Westside.

Hence option C is correct.
