Explanation

In Linux Interprocess Communication (IPC), signals are used to notify a process that a particular event has occurred.

They are asynchronous, meaning they can arrive at any time, regardless of what the process is doing.

Explanation

clrscr() is a function used to clear the console screen in C/C++ (usually with conio.h library).

It helps to remove previous output before displaying new information on the screen.

Explanation

The Control Unit (CU) directs the operation of the Arithmetic Logic Unit (ALU).

It tells the ALU what operation to perform based on the instructions from the program.

Explanation

The CPU (Central Processing Unit) includes:

1. ALU (Arithmetic Logic Unit)
2. CU (Control Unit)
3. Registers (temporary storage inside CPU)

Primary Storage (like RAM) is not part of the CPU; it is part of the main memory.

Explanation

Palmtop computers are small handheld devices and usually do not have disk drives.

Laptops, notebooks, and desktops generally include disk drives for storage.

Explanation

Robots are widely used in automobile manufacturing for tasks like assembling cars with precision and speed.

This is a key application of industrial robotics in automation and production lines.

Explanation

Spooling allows peripheral devices (like printers) to handle data independently, reducing CPU involvement in data transfer.

This frees the CPU to perform other tasks, improving overall system efficiency.

Explanation

cin >> age; is the correct syntax in C++ to take input from the user and store it in the variable age.

The >> operator is used with cin to extract the input value into the variable.

Explanation

Software Engineering focuses on designing, developing, and maintaining software systematically.

It applies engineering principles to ensure quality and reliability in software products.

Explanation

A non-preemptive resource cannot be forcibly taken from a process once it has been allocated — like a printer mid-task.

The resource is released only when the current process finishes using it.
