Explanation

Semiconductor memory is a digital electronic semiconductor device used for digital data storage, such as computer memory.

There are mainly two types of semiconductor memory:

1. random-access memory (RAM) 
2. read-only memory (ROM).
   

Explanation

The Operating System (OS) is the core component that manages hardware and software resources.

It acts as the bridge between user and hardware, enabling all system functions.

Explanation

A NAND gate gives output 0 only when all inputs are 1; otherwise, it outputs 1.

It is the inverse (NOT) of the AND gate.

Explanation

A variable declared with the const keyword in C becomes read-only and its value cannot be modified after initialization.

Attempting to change a const variable will result in a compile-time error.

Explanation

In C programming, preprocessor directives (like #include or #define) begin with the # symbol.

These directives are processed before the actual compilation of code starts.

Explanation

Audio/Video players are media software, not productivity software.

Productivity software includes tools like spreadsheets, word processing, and databases, which help users create, manage, and analyze data.

Explanation

DSL (Digital Subscriber Line) enables internet access by transmitting digital data over the wires of a local telephone network.

DSL uses existing copper telephone lines and separates voice and data signals through different frequency bands.

It provides high-speed internet and offers advantages such as wide availability, cost-effectiveness, and an always-on connection.

Explanation

A standard compact disc (CD) is 120 mm (12 cm) (4.75 inches) in diameter and 1.2 mm (0.05 inch) thick.

This size is widely used for storing data, music, or video.

Explanation

The Transpose() function in MS Excel, helps to interchange the values of rows to columns and vice versa.

It function returns a vertical range of cells as a horizontal range.
