D322 Introduction to IT - Set 3 - Part 1

Correct Answer: Full Backup

A full backup copies all data from the system, making it the most time-consuming but providing the most comprehensive data recovery option.

Correct Answer: Shell

The shell provides a user interface, often allowing command-line or graphical access to interact with the kernel and system functions.

Correct Answer: Software as a Service

SaaS refers to a cloud computing model where software applications are delivered over the internet, often on a subscription basis.

Correct Answer: Scope Definition

Scope definition involves clearly outlining the project's objectives, outcomes, and deliverables, ensuring all stakeholders have a shared understanding.

Correct Answer: DELETE

The DELETE command is used to remove records from a table in a database, often based on specific conditions.

Correct Answer: Convert domain names to IP addresses

DNS (Domain Name System) translates human-readable domain names into numerical IP addresses that computers use to identify each other on a network.

Correct Answer: Real-time code execution

Interpreted languages execute code in real-time, allowing developers to test and see results immediately without compiling the entire program first.

Correct Answer: Preventing unauthorized access to or from a network

Firewalls monitor and control incoming and outgoing network traffic, blocking unauthorized access to protect the network.

Correct Answer: SSL/TLS

SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are cryptographic protocols used to encrypt data during transmission, ensuring secure communication over the internet.

Correct Answer: Operating System

The operating system manages core functions of the computer, including file management, memory allocation, and input/output operations.

Correct Answer: Interpreter

An interpreter translates high-level code into machine code one line at a time, executing each statement before moving on to the next.

Correct Answer: Cache

Cache memory is faster than RAM and is located closer to the processor to quickly access frequently used data.

Correct Answer: LAN

A LAN (Local Area Network) is used to connect computers and devices within a limited geographic area, such as a single building or office.

Correct Answer: Organize and retrieve data

A DBMS is responsible for organizing, retrieving, and managing data in a database, allowing users to query and manipulate data efficiently.

Correct Answer: Primary Key

A primary key is a unique identifier for each record in a relational database, ensuring that no two records have the same value in this field.

Correct Answer: IaaS

Infrastructure as a Service (IaaS) provides virtualized computing resources, such as servers, storage, and networking infrastructure, over the cloud.

Correct Answer: Act as a cache for frequently accessed web pages

A proxy server caches frequently accessed web pages to reduce loading times and improve performance by serving cached content to users.

Correct Answer: Incremental Backup

Incremental backups only capture data that has changed since the last backup, whether it was a full or incremental backup, saving time and storage space.

Correct Answer: Controlling

The controlling phase of project management involves monitoring and measuring project performance to ensure it stays on track and meets its objectives.

Correct Answer: Application Software

Application software is designed to perform specific tasks for the user, such as creating documents, managing data, or editing photos.
