USB stands for Universal Serial Bus. It is a standard connection interface that allows electronic devices to communicate and transfer data with each other. The term "universal" implies that it is widely used and compatible with various devices and operating systems. "Serial" refers to the way data is transmitted in a sequential manner, one bit at a time. "Bus" refers to the pathway or connection through which data is transferred. Therefore, the correct answer is "universal serial bus."

Wi-Fi and LAN are not the same. Wi-Fi is a wireless technology that allows devices to connect to the internet or a network without the need for physical cables. LAN, on the other hand, stands for Local Area Network and refers to a network that connects devices within a limited area, such as a home, office, or school, using wired connections. While both Wi-Fi and LAN can be used to connect devices to a network, they differ in terms of the technology used for connectivity.

VPN stands for Virtual Private Network. A VPN is a technology that allows users to create a secure and encrypted connection over a less secure network, such as the internet. It provides users with a private and secure connection to access resources and services on the internet, while also protecting their data and online activities from potential threats and surveillance. By using encryption and tunneling protocols, a VPN creates a virtual network that extends across a public network, enabling users to browse the internet anonymously and securely.

A modem is a device that modulates and demodulates signals, allowing for the transmission and reception of data over a communication network. The term "modulator demodulator" accurately describes the function of a modem, as it converts digital data from a computer into analog signals for transmission, and then converts the analog signals back into digital data for the receiving computer. Therefore, "Modulator Demodulator" is the correct full form of MODEM.

CCTV stands for closed circuit television. This refers to a system where video surveillance is conducted using cameras that are connected to a limited number of monitors. Unlike broadcast television, CCTV is a closed system that is only accessible to a specific group of people. It is commonly used for security and monitoring purposes in various settings such as homes, businesses, and public spaces.

ICT stands for Information and Communication Technology. This term refers to the use of technology to store, retrieve, transmit, and manipulate information. It encompasses a wide range of technologies such as computers, software, telecommunications, and the internet. ICT plays a crucial role in facilitating communication, improving efficiency, and enhancing productivity in various sectors including education, business, and government.

Ethernet is another name for LAN cable. Ethernet is a technology that is commonly used to connect devices within a local area network (LAN). It provides a means for devices to communicate and transfer data over a wired connection. LAN cables, also known as Ethernet cables, are used to physically connect devices such as computers, routers, and switches to the LAN, allowing for data transmission. Therefore, Ethernet is the correct answer for another name for LAN cable.

The given string "1.42.113.258.9" is an example of an IP address. An IP address is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. It serves as an identifier for the device's location in the network and allows for the routing of data packets between devices. In this case, the string consists of four sets of numbers separated by periods, which is the standard format for IPv4 addresses. However, it is worth noting that the last set, "258", is not a valid octet as it exceeds the range of 0-255.

AIS is an example of an internet service provider. Internet service providers are companies that provide internet access to individuals and businesses. AIS is a specific company that offers internet services to its customers.

HTTPS stands for Hypertext Transfer Protocol Secure. It is a secure version of the HTTP protocol used for communication over the internet. HTTPS ensures that the data exchanged between a user's browser and a website is encrypted and cannot be intercepted or tampered with by attackers. This is achieved through the use of SSL/TLS protocols, which establish a secure connection between the client and the server. By using HTTPS, websites can protect sensitive information such as passwords, credit card details, and personal data from being accessed by unauthorized individuals.
