Daily Internet Test 1

The domain name for commercial users is .com. This is because .com is the most commonly used top-level domain for commercial websites. It is widely recognized and associated with businesses and commercial activities. Other domain extensions like .net, .org, and .id are also available, but .com is specifically designated for commercial purposes.

The correct answer is "Internet protocol" because it is used to identify computers on a network. The Internet Protocol (IP) assigns a unique address to each device connected to the internet, allowing them to communicate with each other. This address is essential for routing data packets across networks and ensuring that they reach the correct destination. The other options, such as Extranet protocol, Intranet protocol, and Interconnect protocol, are not commonly used terms in networking and do not accurately describe the feature of identifying computers on a network.

Berniaga.com is an example of e-commerce because it is an online platform where individuals and businesses can buy and sell products and services. E-commerce refers to the buying and selling of goods and services over the internet, and Berniaga.com fits this definition as it provides a platform for online transactions between buyers and sellers.

Bandwidth refers to the width or capacity of the data channel that is used to transfer data. It represents the amount of data that can be transmitted in a given amount of time. A higher bandwidth allows for faster data transfer, while a lower bandwidth results in slower transfer speeds. Therefore, bandwidth is the correct answer as it accurately describes the width of the data channel used for data transfer.

WiFi stands for Wireless Fidelity. This term is used to describe a wireless networking technology that allows devices to connect to the internet or communicate with each other without the need for physical cables. The term "fidelity" is used to indicate the quality and reliability of the wireless connection.

A computer network used in a wider area is referred to as a Wide Area Network (WAN). Unlike Local Area Networks (LANs) that cover a smaller geographic area, WANs connect multiple LANs over a larger distance. WANs are typically used to connect devices and networks across different cities, countries, or even continents. They utilize various communication technologies, such as leased lines, satellites, or internet connections, to enable data transmission over long distances. WANs are commonly used by organizations to connect their branch offices or remote locations, providing them with access to shared resources and centralized services.

Wireless technology uses high frequency in the spectrum, typically in the range of 2.4 GHz. This frequency range is commonly used for Wi-Fi networks, Bluetooth devices, and other wireless communication technologies. The 2.4 GHz frequency offers a good balance between range and data transfer speed, making it a popular choice for wireless applications.

A file with the extension "rar" is a compression file. RAR stands for Roshal Archive, which is a proprietary archive file format that supports data compression, error recovery, and file spanning. It is commonly used to compress and package multiple files into a single archive, making it easier to store and transfer large amounts of data.

The image above can be identified as an internal modem because it is a device that is installed inside a computer system to provide internet connectivity. It is different from an external modem, which is a separate device that connects to the computer externally. The image does not resemble a LAN card or MAN card, which are network interface cards used for local area networks and metropolitan area networks respectively. Therefore, the correct answer is internal modem.

The given list consists of different web browsers, such as Flock, Safari, Firefox, and Google. However, the word "except" implies that one of the options does not belong to the category of web browsers. Therefore, the correct answer is "Google" as it is not a web browser, but rather a search engine.
