• File Management, Task (Process) Management, and Memory Management are responsibilities of the Operating System (OS)
• Memory Management: Allocates and deallocates RAM to programs, ensuring efficient access for the CPU.
• File Management: Handles the storage, organization, naming, and protection of files on storage devices.
• Task/Process Management: Creates, deletes, and schedules processes (tasks) to ensure proper CPU utilization.

Explanation

A compiler is a language translator that converts high-level code into machine code.

It translates the entire program before execution, allowing the program to run independently.

Explanation

The Entity Relationship (ER) Model visually represents entities, their attributes, and relationships in a database.

It is widely used in database design to define the logical structure before actual implementation.

Explanation

Guided Media uses physical paths like cables (e.g., twisted pair, coaxial, fiber optic).

Hence, it is called Bounded Transmission Media or Wired Media because the signal is guided through a solid medium.

Explanation

Spyware secretly monitors user activity and collects data like passwords, banking details, or browsing habits.

It then transmits this data to a third party without the user's knowledge.

Explanation

Cyber bullying often causes emotional distress, like frustration, fear, anxiety, and low self-esteem.

Happiness is not one of the emotions typically experienced by victims.

Explanation

The source and method of data collection significantly impact the accuracy of the data.

Different sources might have varying levels of reliability and accuracy.

The method used to collect data, whether through surveys, interviews, experiments,

Or other means can also introduce biases or errors.

For example, a survey with leading questions might yield biased results. 

Explanation

Light varies continuously in intensity and wavelength, making it an analog signal.

Analog signals have values that change smoothly over time — just like natural light.

Explanation

An Assembler converts programs written in assembly language into machine language.

It translates mnemonic codes into binary instructions the CPU can execute.
