Explanation

• Machine Language / Assembly is NOT a high-level programming language.
• High-level languages are closer to human language and easier to read.
• Machine and assembly languages are closer to hardware.
• They are used for low-level system control.
• They require more technical understanding than high-level languages.

Explanation

• HTTPS (SSL/TLS) is used to establish a secure channel of communication over a potentially insecure network.
• SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are cryptographic protocols.
• They encrypt data to protect it from hackers during transmission.
• They ensure data confidentiality, integrity, and authentication.
• Commonly used in secure websites (HTTPS connections).

Explanation

• Database normalization reduces data redundancy in a database.
• It organizes data into well-structured tables.
• It removes duplicate (repeated) data.
• It improves data consistency and efficiency.
• It helps in reducing data anomalies during operations.

Explanation

• Pressure in gases is due to the collision of gas molecules with the walls of the container.
• Gas molecules are in constant random motion.
• They continuously strike the container walls.
• These collisions create force per unit area (pressure).
• More collisions mean higher pressure.

Explanation

• First Law of Thermodynamics explains the conservation of energy.
• Energy cannot be created or destroyed, only transformed.
• It applies to all physical and chemical processes.
• Total energy of a closed system remains constant.
• Heat and work are forms of energy transfer.

Explanation

• Photosynthesis produces glucose and oxygen.
• Green plants use sunlight, water, and carbon dioxide.
• This process occurs in chloroplasts using chlorophyll.
• Glucose is used as food for energy and growth.
• Oxygen is released as a byproduct into the atmosphere.

Explanation

• A stretched spring possesses potential energy.
• When a spring is stretched or compressed, energy is stored in it.
• This stored energy is called elastic potential energy.
• It can be converted into kinetic energy when released.
• The more the stretch, the more energy is stored.
