In a triangle ABC, incentre is O and ∠BOC = 110o, then the measure of ∠BAC

Detailed Solution: Question 13

As given,
∠BOC = 110o
And, we know incentre of a triangle is a point where angle bisector of triangles meet.
So, which means ∠OCB =∠OBC
∠BOC +∠OCB+∠OBC = 180o
⇒∠OCB + ∠OBC = 180o − 110o
⇒∠OCB +∠OBC = 70o

Since, ∠ABC = 2∠OBC
∠ACB = 2∠OCB
So, ∠ABC+∠ACB = 2 × 70o
⇒∠ABC + ∠ACB = 140o
Now, in triangle ABC.
∠ABC +∠BAC +∠ACB = 180o
⇒∠BAC  +140o = 180o
⇒∠BAC = 180o − 140o
⇒∠BAC = 40o
Hence, the correct answer is 40o.

There are 17 persons in a group. The average age of 16 persons among them is 60.50 years and the age of 17th person is 8 years more than the average age of all the 17 persons. What is the age of the 17th person?

Detailed Solution: Question 15

Let the average age of all the 17 persons = X years
Age of 17th persons = X + 8 years 
16 × 60.50 + X + 8 = 17 × X
976 = 16X 
X = 61 
So the answer = 61 + 8 = 69 years
Hence, Option D is correct.

The shadow of a building is 10 m long when the point of rise of the sun is 60°. Discover the building's stature.

Detailed Solution: Question 19


Let AB be the building and AC be its shadow.
Then, AC = 20m and ∠ACB = 60°. Let AB = x m.
Presently AB/AC = tan 60° = √3 => x/10 = √3
=> x = 10√3m = (10 * 1.732) m = 17.32m.
∴ Height of the building is 17.32m.

Which of the following 802 standard provides for a collision free protocol?

Detailed Solution: Question 23

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.

Following is/are the reasons for process suspension.

Detailed Solution: Question 25

Reasons for Process Suspension:
Swapping parent process:
- When the operating system needs to free up memory resources, it may decide to swap out a parent process. This means that the process is moved from main memory to secondary storage (such as a hard disk) temporarily.
- Swapping allows the operating system to prioritize active processes and allocate resources efficiently.
Inter request:
- Process suspension can occur when a process needs to wait for an external event or resource before it can continue executing.
- For example, if a process is waiting for user input or waiting for a file to be read from the disk, it may be temporarily suspended until the requested input or data becomes available.
Timing:
- Timing can also be a reason for process suspension. This occurs when a process is scheduled to be suspended for a specific period of time, allowing other processes to execute during that time frame.
- Timing-based suspensions are often used in multitasking operating systems to ensure fair allocation of resources among different processes.
All of the above:
- The correct answer to the question is "d. All of the above" because all of the mentioned reasons (swapping parent process, inter request, and timing) can lead to process suspension.
In summary, process suspension can occur due to various reasons such as the need for memory management (swapping parent process), waiting for external events or resources (inter request), and timing-based scheduling. All of these reasons contribute to the efficient allocation of resources and fair execution of processes in an operating system.

In ______ OS, the response time is very critical.

Detailed Solution: Question 26

Explanation:
In real-time operating systems (RTOS), the response time is very critical. Here is a detailed explanation:
Real-time Operating System (RTOS):
- An operating system designed for systems that require precise and predictable response times.
- It is used in applications such as industrial control systems, aerospace systems, medical devices, etc.
Response Time:
- The time it takes for a system to respond to a request or event.
- In real-time operating systems, the response time needs to be very fast and predictable.
Importance of Response Time:
- In certain applications, such as control systems or critical medical devices, even a small delay in response time can have serious consequences.
- Real-time operating systems are designed to ensure that the response time is as fast and predictable as possible.
Comparison with other Operating Systems:
- Multitasking Operating System: In multitasking operating systems, response time is important, but not as critical as in real-time operating systems. These operating systems prioritize multiple tasks and allocate resources accordingly.
- Batch Operating System: In batch operating systems, response time is not critical as the system processes a batch of tasks without any user interaction.
- Online Operating System: In online operating systems, response time is important, but not as critical as in real-time operating systems. These operating systems prioritize online user interactions but may not guarantee precise response times.
Conclusion:
- In real-time operating systems, the response time is very critical due to the nature of applications that require precise and predictable response times.
- Real-time operating systems are designed to prioritize and optimize response times to ensure fast and predictable system behavior.
