To return the desired result "MCQ@ Questions" in cell C1, you can use the CONCATENATE function or the ampersand (&) operator in Excel.
Here is the detailed solution:
1. The correct function to use in this case is the CONCATENATE function or the ampersand (&) operator.
2. The CONCATENATE function allows you to join multiple text strings together. It takes multiple arguments and concatenates them into a single string.
3. The ampersand (&) operator also performs the same function as the CONCATENATE function and joins text strings together.
4. In this case, you want to join the value in cell A1 ("MCQ") with the text string "@" and the value in cell B1 ("Questions").
5. To achieve this, you can use the following formula in cell C1:
=CONCATENATE(A1, "@", B1) or =A1 & "@" & B1
This formula will concatenate the text in A1, the "@" symbol, and the text in B1, resulting in the desired output "MCQ@ Questions" in cell C1.
Therefore, the correct answer is option C: =A1 & "@" & B1.

Number of Hosts That Can Successfully Send Data Simultaneously on Ethernet
There are certain limitations to the number of hosts that can successfully send data simultaneously on Ethernet. The answer to this question is:
Answer: B. 2
Explanation:
Ethernet is a widely used technology for local area networks (LANs) and it uses a shared medium for communication. The number of hosts that can send data simultaneously on Ethernet is limited due to the following reasons:
1. Collision Domain: In Ethernet, all devices connected to the same network segment share the same collision domain. A collision occurs when two or more devices transmit data at the same time, resulting in data corruption. To avoid collisions, Ethernet uses a carrier sense multiple access with collision detection (CSMA/CD) mechanism. This means that only one device can successfully transmit data at a time, while others must wait for their turn.
2. Half-Duplex Mode: Ethernet operates in either half-duplex or full-duplex mode. In half-duplex mode, a device can either transmit or receive data at a given time, but not both simultaneously. Therefore, only two hosts can communicate at the same time - one sending and the other receiving.
3. Bandwidth Sharing: Ethernet shares the available bandwidth among all the connected devices. If multiple hosts try to transmit data simultaneously, the available bandwidth gets divided, resulting in lower throughput for each host. To ensure efficient data transmission, it is recommended to limit the number of hosts sending data simultaneously.
In summary, due to the collision domain, half-duplex mode, and bandwidth sharing, Ethernet allows only two hosts to successfully send data simultaneously.

Actual execution of instructions in a computer takes place in the ALU (Arithmetic Logic Unit).
The ALU is a crucial component of the computer's central processing unit (CPU) responsible for performing arithmetic and logical operations on data. It carries out the actual execution of instructions, manipulating data according to the instructions provided by the program.
Here is a breakdown of the key points:
1. ALU (Arithmetic Logic Unit):
- The ALU is a component of the CPU that performs arithmetic and logical operations.
- It is responsible for executing instructions provided by the program.
- The ALU operates on binary data, performing operations like addition, subtraction, multiplication, division, and logical operations such as AND, OR, and NOT.
- It is designed to handle various data types, including integers, floating-point numbers, and binary-coded decimal (BCD) numbers.
2. Control Unit:
- The control unit is another component of the CPU, but its main function is to coordinate and control the operations of other components.
- It fetches instructions from memory and sends signals to the ALU and other units to perform the required operations.
- While the control unit plays a vital role in the overall functioning of the computer, it is not directly involved in the execution of instructions.
3. Storage Unit:
- The storage unit, which includes the memory and storage devices, is responsible for storing data and instructions.
- The ALU fetches instructions from the storage unit and performs the necessary operations on the data stored in memory.
- However, the actual execution of instructions takes place in the ALU, not in the storage unit itself.
Therefore, the correct answer is A: ALU. The ALU is where the actual execution of instructions in a computer takes place.

Starvation refers to a situation in which a process is ready to execute but is continuously denied access to a processor in deference to other processes.
Explanation:
- Starvation occurs when a process is unable to proceed or make progress due to being continually bypassed or overlooked in favor of other processes.
- It often happens in systems that use scheduling algorithms to determine which process gets access to the processor.
- The process that is continuously denied access to the processor is said to be starving.
- Starvation can occur due to various reasons, such as:
- Inefficient scheduling algorithms that prioritize certain processes over others.
- Resource limitations, where a process requires a specific resource that is not available or is being monopolized by other processes.
- Starvation can have negative impacts on system performance, as it can lead to delays and decreased efficiency.
- To address starvation, it may be necessary to adjust scheduling algorithms or allocate resources more fairly among processes.
- Overall, starvation is a situation that can occur in systems where processes compete for resources, and it can impact the overall performance and fairness of the system.
