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.

To solve this problem, we need to follow these steps:
1. Select Rows 5 and 6: This means we need to highlight or select both Row 5 and Row 6 in the spreadsheet.
2. Choose "Insert" > "Row": Navigate to the menu bar and click on the "Insert" option. From the drop-down menu, select "Row" to insert new rows.
Based on the given question, the correct answer is option A: 2 Rows will be inserted after Row 4. Here's why:
- When we select Rows 5 and 6, it means we are choosing to insert new rows after these selected rows.
- Since Row 5 is before Row 6, inserting rows after Row 4 means that the new rows will be inserted after Row 4 and before Row 5.
- Therefore, the new rows will be inserted after Row 4 but before Row 5, resulting in 2 rows being inserted after Row 4.
In summary, selecting Rows 5 and 6 and choosing to insert rows will add 2 new rows after Row 4.

Explanation:
The communication mode that supports two-way traffic but in only one direction at a time is Half-duplex.
Here is a detailed explanation:
1. Simplex:
- Simplex communication mode allows data transmission in only one direction.
- It is a one-way communication mode where the sender can only send data, and the receiver can only receive data.
- There is no possibility of two-way communication in simplex mode.
2. Half-duplex:
- Half-duplex communication mode allows two-way traffic but in only one direction at a time.
- In this mode, both the sender and receiver can transmit and receive data, but not simultaneously.
- When one party is transmitting, the other party can only receive, and vice versa.
- It is like a walkie-talkie or a push-to-talk system where only one party can speak at a time.
3. Three-quarter's duplex:
- There is no such communication mode called "Three-quarter's duplex."
- It is an incorrect option.
4. Full duplex:
- Full-duplex communication mode allows simultaneous two-way traffic.
- In this mode, both the sender and receiver can transmit and receive data at the same time.
- It is like a regular telephone conversation where both parties can talk and listen simultaneously.
Therefore, the correct answer is Half-duplex (option B) as it supports two-way traffic but in only one direction at a time.
