Quiz 10- SEC A

Explanation
The email address "f_hassad@localhost" is probably not a valid email address because "localhost" is typically used to refer to the current device or local network, not a valid domain for email addresses.

Explanation
The given answer, ".army," is not a top-level computer domain. The other options, ".edu," ".org," and ".gov," are all examples of top-level domains that are commonly used for educational institutions, non-profit organizations, and government entities, respectively. However, ".army" is not a recognized top-level domain and is not commonly used for computer domains.

Explanation
Google is a search engine because it is a web-based tool that allows users to search for information on the internet. It indexes billions of web pages and provides relevant search results based on the user's query. Google's search engine algorithm is designed to deliver accurate and comprehensive results, making it one of the most popular and widely used search engines worldwide.

Explanation
A domain name ending with "org" is typically associated with an organization. This is because "org" is short for "organization" and is commonly used by non-profit organizations, educational institutions, and other non-commercial entities. Unlike domain names ending with "com" (commercial) or "net" (network), "org" indicates that the website is affiliated with an organization rather than a commercial or network site.

Explanation
An email address is typically made up of two parts: the local part and the domain part. The local part is the part before the "@" symbol, which identifies the specific user or mailbox within the domain. The domain part is the part after the "@" symbol, which identifies the domain or organization that manages the email service. Together, these two parts form a complete email address, allowing messages to be sent and received between users.

Explanation
POP3 (Post Office Protocol version 3) is a simple protocol used for fetching e-mail from a mailbox. It allows users to retrieve their emails from a mail server and download them to their local device. POP3 is widely supported by email clients and servers and is commonly used for accessing and managing email accounts. It is different from POP2 and IMAP in terms of features and functionality. POP3 is a reliable and efficient protocol for retrieving emails, making it the correct answer in this case.

Explanation
The correct answer is "Home Page." The front page or main page of a website is commonly referred to as the home page. It is the initial page that users see when they visit a website and usually contains an overview of the website's content and navigation options to explore further.

Explanation
Windows is not a search engine. It is an operating system developed by Microsoft. Bing, Google, and Yahoo are all search engines that allow users to search for information on the internet.

Explanation
Moving from one website to another is called browsing. Browsing refers to the act of navigating through different websites or web pages using a web browser. It involves searching for information, accessing web pages, and interacting with various online content. Browsing allows users to explore the internet and access different websites for different purposes such as reading articles, watching videos, shopping, or communicating with others.

Explanation
A computer on the internet is identified by an IP address. An IP address is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. It serves as the computer's digital address, allowing it to send and receive data over the internet. Unlike e-mail addresses or street addresses, which are specific to individuals or physical locations, an IP address is used to identify and locate devices on a network. Therefore, an IP address is the correct answer for identifying computers on the internet.
