Correct Answer: A. Extensible Markup Language

• **Extensible Markup Language** = XML is a markup language designed to store and transport data in a format that is both human and machine-readable. • **Custom tags** — unlike HTML, XML allows users to define their own, making it widely used in web services for data exchange. • 💡 Wrong-option analysis: [Extra Modern Language]: This is an incorrect expansion; [X-linked Markup Language]: This is an incorrect expansion; [Example Markup Language]: This is an incorrect expansion.

Correct Answer: A. Simple Mail Transfer Protocol

• **Simple Mail Transfer Protocol** = SMTP is the standard protocol used for sending email messages across the internet. • **IMAP or POP3** — most modern email clients use these for receiving mail, while SMTP specifically handles outgoing mail transmission. • 💡 Wrong-option analysis: [Secure Mail Text Protocol]: This is an incorrect expansion; [Standard Mail Transfer Program]: This is an incorrect expansion; [Single Mail Transmission Program]: This is an incorrect expansion.

Correct Answer: B. Virtual Private Network

• **Virtual Private Network** = A VPN creates a secure and encrypted connection over a less secure network, such as the public internet. • **Masking their IP address** — this helps protect user privacy and physical location, and organizations use VPNs for secure remote access. • 💡 Wrong-option analysis: [Virtual Public Network]: This is an incorrect expansion; [Validated Private Network]: This is an incorrect expansion; [Visual Private Network]: This is an incorrect expansion.

Correct Answer: D. Local Area Network

• **Local Area Network** = A LAN is a computer network that interconnects computers within a limited area such as a residence, school, or office. • **Ethernet and WiFi** — these are the most common technologies used for LANs, offering high data transfer speeds and low latency. • 💡 Wrong-option analysis: [Land Area Network]: This is an incorrect expansion; [Local Access Network]: This is an incorrect expansion; [Logical Area Network]: This is an incorrect expansion.

Correct Answer: D. Secure Sockets Layer

• **Secure Sockets Layer** = SSL is a standard security technology for establishing an encrypted link between a web server and a browser. • **TLS** — while technically succeeded by this, the term SSL is still commonly used to ensure data privacy and integrity. • 💡 Wrong-option analysis: [Secure System Level]: This is an incorrect expansion; [Standard Security Layer]: This is an incorrect expansion; [System Software Link]: This is an incorrect expansion.

Correct Answer: C. Transmission Control Protocol

• **Transmission Control Protocol** = A core protocol of the Internet Protocol Suite that provides reliable and ordered delivery of data packets. • **Reliable and ordered delivery** — This is TCP's primary function, ensuring data integrity and proper sequence between sender and receiver. • 💡 Wrong-option analysis: [Transfer Control Process]: Incorrect terms 'Transfer' and 'Process'; [Telecommunication Control Protocol]: Incorrect term 'Telecommunication'; [Technical Communication Program]: Incorrect terms 'Technical' and 'Program'.

Correct Answer: C. Wireless Local Area Network

• **Wireless Local Area Network** = A local area network that uses wireless communication to link devices. • **WiFi** — This is the most popular implementation of a WLAN, allowing users to stay connected while moving within a building. • 💡 Wrong-option analysis: [Wired Local Area Network]: 'W' stands for 'Wireless', not 'Wired'; [Wide Local Area Network]: 'W' stands for 'Wireless', not 'Wide'; [Web Local Area Network]: 'W' stands for 'Wireless', not 'Web'.

Correct Answer: A. Graphics Interchange Format

Correct Answer: B. JavaScript Object Notation

• **JavaScript Object Notation** = A lightweight data-interchange format that is easy for humans to read and write. • **XML** — JSON has largely replaced XML in many modern web APIs for data transmission between servers and web applications. • 💡 Wrong-option analysis: [JavaScript Open Network]: Incorrect term 'Open Network'; [Java Standard Object Notation]: Incorrect language 'Java' instead of 'JavaScript'; [Joint System Online Network]: Incorrect terms 'Joint System Online Network'.

Correct Answer: B. Media Access Control

• **Media Access Control** = A unique identifier assigned to a network interface controller for communications on a network. • **IP addresses** — Unlike IP addresses, which can change, MAC addresses are generally permanent and hard-coded into the device's hardware. • 💡 Wrong-option analysis: [Multi-Access Control]: Incorrect term 'Multi'; [Mobile Access Code]: Incorrect terms 'Mobile' and 'Code'; [Machine Access Control]: Incorrect term 'Machine'.
