UPSSSC JE Mechanical Paper 1 Mock Test - 10 - Question 11

Direction: Read the following passages carefully and answer the question that follows.
Why doesn't the air remain still ? The reason is that air, when it becomes heated, becomes lighter, and it rises. When it rises, other air moves in to take its place. The temperature of air becomes like the surface of the earth over which it travels. Over dry land, the air can become very hot. Then, when the sun goes down, it cools off quickly. Over the water air heats up more slowly and cools off more slowly. These changes cause the movement of air,which we call wind.

Q.  Over dry land, the air?

Detailed Solution: Question 11

Over dry land, the air becomes very hot & when the Sun goes down it cools off quickly

There are 8 persons, P, Q, R, S, T, U, V and W sitting around a rectangular table in such a way that four of them sit at four corners of the table while four sit in the middle of each of four sides. Persons who sit at the corners face outside the centre while those who sit in the middle of the side face inside.
Q sits second to the right of P. R sits third to the left of W. R faces inside. T sits third to the left of U. V sits second to the left of U. R is not an immediate neighbor of P.
Q. Four of the following five are alike in some manner hence belong to a group. Find the one that doesn’t belong to that group.

Detailed Solution: Question 13

From the final arrangement, we get, R doesn’t belong to that group as except for R, all the others are facing outside.
Hence, Option D is correct.
References:
Q sits second to the right of P.
Inferences:
From the above reference, we get two different cases:
In case 1, P sits at the corner or in the middle of the side of the table.

References:
R is not an immediate neighbor of P.
R faces inside.
R sits third to the left of W.
Inferences:
From the above references, we get different cases for R, in case 1(a) in which R faces P and in case 1(b) R faces Q.

References:
T sits third to the left of U.
V sits second to the left of U.
Inferences:
So, from this case 1(b) and case 2 will be eliminated as there is no possible place for V in these cases after placing U and T. Hence, we get our final arrangement in which S sits on the immediate left of P and V sits on the immediate right of R.
Final arrangement:

UPSSSC JE Mechanical Paper 1 Mock Test - 10 - Question 14

​In this questions, a number series is given with one term missing. Choose the correct alternative that will continue the same pattern and fill in the black spaces.

  • Electro-mechanical mice have been largely replaced by optical or laser mice, which use light sensors instead of a ball to track movement.

Additional Information

  • Electro-magnetic: These principles are used in devices like speakers and headphones, but not in the functioning of a computer mouse.
  • Electro-operational: The term "electro-operational" does not have a clear meaning in the context of a computer mouse.
  • Electro-optical: Optical mice do use light sensors to track movement, but this is only one part of the overall electro-mechanical process that enables a mouse to function.

UPSSSC JE Mechanical Paper 1 Mock Test - 10 - Question 28

Which protocol is used to report error message?

Detailed Solution: Question 28

Protocol Used to Report Error Messages
The protocol used to report error messages is ICMP (Internet Control Message Protocol). ICMP is a network layer protocol that is responsible for reporting errors and providing diagnostic information in IP networks. It is an integral part of the Internet Protocol Suite and is used by network devices to communicate error messages and control information.
ICMP provides the following functions:
- Error Reporting: ICMP is primarily used to report errors that occur during the transmission of IP packets. When a network device encounters an error, such as a destination unreachable or a time exceeded, it will generate an ICMP message to inform the sender of the error.
- Network Testing and Troubleshooting: ICMP also includes tools that can be used for network testing and troubleshooting purposes. For example, the "ping" command uses ICMP echo request and echo reply messages to test the reachability and round-trip time of a network host.
- Path MTU Discovery: ICMP is used for Path Maximum Transmission Unit (PMTU) discovery. It allows network devices to determine the maximum size of a packet that can be transmitted without fragmentation along a given path.
- Router Discovery: ICMP Router Discovery messages are used by hosts to discover neighboring routers on an IP network.
In conclusion, ICMP is the protocol used to report error messages in IP networks. It plays a crucial role in error reporting, network testing, troubleshooting, and other network management tasks.

UPSSSC JE Mechanical Paper 1 Mock Test - 10 - Question 29

Inter process communication can be done through ______.

Detailed Solution: Question 29

Inter Process Communication (IPC)
Inter Process Communication (IPC) refers to the mechanisms and techniques used by different processes running on a computer system to communicate and share data with each other. It allows processes to exchange information, synchronize their activities, and coordinate their actions.
Methods of Inter Process Communication
There are several methods of IPC that can be used for communication between processes. These methods include:
1. Mails:
- Processes can communicate with each other by sending messages through a mailbox or a message queue.
- Messages can be exchanged asynchronously, allowing processes to communicate even if they are not running at the same time.
- This method is commonly used in message-oriented middleware systems.
2. Messages:
- Processes can communicate by sending messages directly to each other.
- Messages can be sent using various protocols, such as TCP/IP or UDP/IP.
- This method allows for both synchronous and asynchronous communication between processes.
3. System Calls:
- Processes can use system calls provided by the operating system to communicate with each other.
- System calls such as pipe, shared memory, and sockets can be used for IPC.
- This method allows for efficient and reliable communication between processes.
4. Traps:
- Processes can use software interrupts or traps to communicate with the operating system or other processes.
- Traps can be used to request services from the operating system or to notify other processes about events.
- This method is commonly used in event-driven systems.
In conclusion, inter process communication can be done through various methods such as mails, messages, system calls, and traps. The choice of IPC method depends on the requirements of the system and the nature of the communication between processes.
