• It doesn't necessarily enable all internet services for corporate users or block them from using internet services entirely; rather, it's about managing and securing this usage.
• It also doesn't inherently make internet usage more efficient, as it can sometimes add latency due to the extra steps of data inspection and filtering.

The correct answer is 8, 256

Key Point

• ASCII stands for American Standard Code for Information Interchange.
• The original ASCII standard uses 7 bits, allowing it to represent up to 128 characters (2⁷). It includes upper-case and lower-case Latin letters, digits, basic punctuation, and some control characters.
• Extended ASCII expanded the ASCII standard by utilizing the eighth bit of the byte, effectively doubling the number of possible characters from 128 to 256 (2⁸).
• With this extension, the ASCII set can cover more characters like enhanced graphic symbols, additional punctuation marks, special characters, and diacritical marks.
• The extra characters in the "upper half" (values 128-255) of the Extended ASCII table can vary depending on the specific implementation.
• The usage of ASCII and Extended ASCII has decreased with the advent of more universal standards, such as Unicode, which can support a multitude of characters from many different languages and also includes emojis.

The correct answer is To mark keywords or topics for easy searchability.

Key Points

• The primary purpose of hashtags in social media is to mark keywords or topics for easy searchability.
• Hashtags are words or phrases preceded by a hash (#) symbol. When you use a hashtag in a social media post, it makes your post searchable by that hashtag.
• This means that people who are interested in that topic can find your post by searching for the hashtag.
• For example, if you post a photo of your cat with the hashtag #cats, people who are interested in cats can find your photo by searching for that hashtag.

Additional InformationHashtags can also be used to:

• Connect with other people who are interested in the same topics.
• Track trends and topics that are popular on social media.
• Promote your brand or business.

The correct answer is TCP/IP.

• URL stands for Uniform Resource Locator.
  • Every web page that is displayed on the Internet has a specific address associated with it. This address is known as the URL.
  • It tells us the location of the web page being displayed and other related information.

The correct answer is Interconnection and networks.

Key Points

• Internet:
  • The term Internet is derived from the words interconnection and networks. Hence, Option 4 is correct.

  • WAN(Wide Area Network) 

The correct answer is 80.

Key Points

• In computer networking, a port is a communication endpoint.
• At the software level, within an operating system, a port is a logical construct that identifies a specific process or a type of network service.
• Port numbers are sometimes seen in web or other uniform resource locators (URLs).
• By default, HTTP uses port 80 and HTTPS uses port 443, but a URL like http://www.example.com:8080/path/ specifies that the web browser connects instead to port 8080 of the HTTP server.
