Explanation

Information is the output from a computer that results from processing input data.

Data is the input, and the computer processes it to produce useful information.

Data (input) → Processing → Information (output)

Explanation

• If the pH value is greater than 7, the solution is basic (also known as alkaline).
• This means that the concentration of hydroxide ions (OH-) is higher than the concentration of hydrogen ions (H+).

Key Points:

• pH < 7: Acidic
• pH = 7: Neutral
• pH > 7: Basic (or alkaline)

Explanation

The direction of the magnetic field lines inside a bar magnet is from south pole to north pole.

This is the opposite direction of the field lines outside the magnet, which go from the north pole to the south pole.

Explanation

An algorithm is a sequence of instructions in a computer language that is designed to solve a specific problem or achieve a particular goal.

It's a step-by-step procedure to get the desired results.

Explanation

• A LAN is a computer network that connects devices in a limited geographical area, such as an office building, campus, or home.
• It's perfect for connecting different computers in an organized manner within an office building.

Note:

• MAN (Metropolitan Area Network): Covers a larger area, like a city or town.
• WAN (Wide Area Network): Covers a vast geographical area, like a country or continent.

Explanation

A supercomputer is another name for a high-performance computer (HPC).

Supercomputers are powerful computers that are designed to execute a large number of instructions at an extremely high speed.

It making them ideal for scientific simulations, weather forecasting, cryptography, and other compute-intensive tasks.

Explanation

A DC motor is an electrical machine that converts electrical energy into mechanical energy.

It uses electrical current to generate a magnetic field that interacts with the motor's magnets.

It causing the motor to rotate and produce mechanical energy.

Explanation

Ohm's Law is valid only if the temperature of the conductor remains constant.

If the temperature changes, the resistance of the conductor may change, and Ohm's Law may not hold.

Explanation

Fats are typically solids at ordinary room temperature (around 20-25°C or 68-77°F).

However, they can melt and become liquids when heated to a higher temperature.

Explanation

The functional group -COOH is the carboxyl group, which is a characteristic functional group of carboxylic acids.

Carboxylic acids are a class of organic compounds that contain this group, examples include:

• Formic acid (HCOOH)
• Acetic acid (CH3COOH)
• Citric acid (C6H8O7)
