Explanation

The Control Unit (CU) directs and coordinates most operations of the computer by managing the flow of data and instructions.

It tells the ALU, memory, and I/O devices how to respond to instructions.

Explanation

In C, getchar() reads a single character from standard input but requires pressing "Enter" to submit the input.

The input is buffered, meaning it waits for the newline (n) before processing the character.

Explanation

A compiler is system software that translates the entire high-level language source code into machine-level object code at once.

It checks for errors during translation and produces a separate executable file.

Explanation

A supercomputer is designed to perform trillions of instructions per second, making it the fastest type of computer for complex computations.

It is used in areas like climate modeling, scientific simulations, and cryptography.

Explanation

Bluetooth is a short-range wireless technology.

It allows devices to communicate with each other over short distances, usually up to 10 meters.

It uses low-power radio waves to transmit data and voice between devices.

Bluetooth was created by Ericsson, a telecom company, in 1994.

Explanation

Explanation

Data arranged in intelligible form is called information.

Information is processed data that is meaningful and useful for decision-making and analysis.

Explanation

 The study of enciphering and encoding (on the sending end), and deciphering and decoding (on the receiving end) is called cryptography.

Cryptography from the Greek κρυπτός (kryptos), or hidden, and γράφειν (graphia), or writing.

Explanation

Software piracy is the illegal copying, distribution, or use of software without proper licensing.

It especially refers to unauthorized commercial resale or use of software for profit.

Explanation

Expansion slots like AGP (Accelerated Graphics Port), PCI (Peripheral Component Interconnect), and ISA (Industry Standard Architecture) are used to add extra hardware (graphics cards, sound cards, etc.) to a computer.

These slots enhance the computer’s capabilities by allowing external components to be connected directly to the motherboard.
