Data Transfer | MCQs

Explanation

Bandwidth refers to the amount of data transmitted per second.

It is measured in bits per second (bps).

It indicates the speed or capacity of a network connection.

Explanation

Full duplex mode allows communication in both directions simultaneously.

In contrast, half duplex mode permits communication in both directions, but not at the same time

Simplex mode allows communication only in one direction.

Explanation

Transmission means sending or passing on data or signals.

The opposite (antonym) is Hold, which means to keep or retain without sending.

Transmission means ڈیٹا یا سگنل بھیجنا یا پاس کرنا

Hold means بھیجے بغیر رکھنا یا برقرار رکھنا

Explanation

The transfer of data from one place to another is called data communication.

It involves sending data through a communication medium like cables or wireless signals.

Explanation

A transmission medium is a channel through which data is transmitted — satellite systems are used to transmit signals over long distances.

LED TV or video camera are devices, not mediums for data transmission.

Explanation

Wireless communication allows quick, remote data transfer without physical connections.

It's commonly used by agencies for mobility, flexibility, and real-time communication.

Explanation

Infrared communication supports data transfer rates typically ranging from 100 Kbps to 4 Mbps.

It is used in short-range, line-of-sight applications like remote controls and some wireless devices.

Explanation

Both software and physical parts work together to transfer data in a computer system.

Software parts, such as operating systems, device drivers, and data transfer protocols, manage and direct data transfer.

Physical parts, like buses, ports, cables, network interface cards, and storage devices, physically move the data.

Explanation

Receiver: A device that accepts a signal from the transmission system and converts it into a usable form for the destination device.

Explanation

Input and Output are used as a medium of communication between the external environment and the CPU.
