The keyboard is the primary device for entering text and commands into a computer. It is specifically designed to allow efficient data entry for users.

An operating system is software that manages the computer's hardware and software resources. It serves as the interface between the user and the computer, ensuring efficient task management.

The monitor is the device that displays images, text, and video output from the computer. It provides the visual interface for user interaction.

A hard drive is a non-volatile storage device that maintains data even when the computer is turned off. It is used for long-term data storage and file retention.

Ctrl + C is the standard keyboard shortcut used to copy selected text. This function allows users to quickly duplicate content for later use.

A folder is used to organize and store files on a computer. It helps users keep their data arranged in a logical and easily accessible structure.

The Recycle Bin holds deleted files temporarily, allowing users to recover them if needed. This feature prevents accidental loss of important data by providing a safety net.

A web browser's main function is to access and display websites over the internet. It retrieves and renders files from web servers so that users can view and interact with online content.

RAM stands for Random Access Memory, a type of volatile memory that temporarily stores data for active processes. It allows the computer to access and process data quickly while running applications.

A computer virus is a type of malicious software that can infect a computer and spread to others. Its primary goal is to disrupt operations, steal information, or damage system performance.

Cloud storage refers to storing data on remote servers accessed over the Internet. It allows users to backup and access their files from multiple devices without relying solely on local storage.

Updating software regularly helps to patch security vulnerabilities and add new features. It ensures that the system operates efficiently and remains protected against emerging threats.

An operating system manages hardware resources by allocating memory, processing time, and input/output access among various applications. This ensures that each program gets the necessary resources to operate efficiently.

Using unreliable third-party software can introduce malware and poorly optimized code into your computer system. This increases the risk of viruses, data breaches, and overall system instability.

Strong, unique passwords reduce the likelihood that a hacker can gain unauthorized access to your accounts. This practice prevents a single compromised password from endangering multiple sensitive systems.

Drivers are software components that help the operating system communicate with hardware devices. They act as intermediaries that allow hardware and software to work together seamlessly.

Regular backups provide a method to restore data in the event of hardware failure, accidental deletion, or cyberattack. They are a critical component of data security because they ensure that vital information can be recovered promptly.
