Explanation

The AND gate performs logical multiplication, outputting 1 only when all its inputs are 1.

It is also known as a conjunction gate in digital logic.

Explanation

1 PB = 1,000 Terabytes

1 TB = 1,000 GB

So, 1 PB = 1,000 × 1,000 = 1,000,000 GB

Explanation

Digital media is used to transmit information in the form of binary data (0s and 1s) in electronic devices.

It includes texts, images, audio, and video transmitted through digital signals.

Explanation

The XNOR gate (Exclusive-NOR) gives an output of 1 when all inputs are the same, either all 0s or all 1s.

It is the inverse of the XOR gate.

Explanation

Logic gates are the fundamental building blocks of digital systems.

The AND, OR, and NOT gates are the most fundamental logic gates.

The NAND and NOR gates are called universal gates because they can be combined to produce OR, AND, and NOT gates.

Explanation

A soft copy is an electronic version of data, such as a file or document, stored digitally.

Soft copies are typically viewed on a computer or mobile device screen.

Explanation

The digital computer, capable of processing data in binary code (0s and 1s), was primarily developed in the USA.

John Vincent Atanasoff, an American-Bulgarian physicist, invented the first electronic digital computer in the 1930s at Iowa State College.
