2. _________ is the secure version of the most common protocol for web browsing, encrypting traffic through TLS/SSL.

HTTPS is the secure version of the most common protocol for web browsing. It encrypts traffic through TLS/SSL, ensuring that the data transmitted between a user's browser and a website is secure and protected from unauthorized access or tampering. This added layer of security is particularly important when sensitive information, such as passwords or credit card details, is being transmitted over the internet. By using HTTPS, websites can provide a safer browsing experience for their users and protect their data from potential threats.

7. _________allows you to login to remote devices but the communication is unencrypted.

Telnet is a protocol that enables users to remotely log in to devices, but it does not provide encryption for the communication. This means that any data transmitted during the Telnet session, including login credentials and sensitive information, can be intercepted and read by unauthorized individuals. As a result, Telnet is considered insecure and is not recommended for use in environments where data confidentiality is important.

8. _________ is a protocol for transferring files that is simple and has no authentication.

TFTP (Trivial File Transfer Protocol) is a protocol used for transferring files that is simple and does not require authentication. It is commonly used for transferring configuration files and firmware to network devices. TFTP does not provide any security features like encryption or user authentication, making it suitable for simple file transfers in non-sensitive environments.

15. _________ is a mail protocol that keeps "state" (Read, replied, deleted, etc.).

IMAP4 is a mail protocol that keeps "state" of emails, meaning it tracks whether an email has been read, replied to, deleted, etc. Unlike POP3, which only downloads emails to a device without keeping track of their status, IMAP4 allows users to access their emails from multiple devices while maintaining the same state across all devices. This means that if an email is marked as read on one device, it will also be marked as read on all other devices connected to the same email account.

18. Name the four layers of the TCP/IP suite.

The TCP/IP suite consists of four layers: the Application layer, which provides services to the user applications; the Transport layer, which ensures reliable delivery of data between hosts; the Internet layer, which handles the addressing and routing of data packets across networks; and the Link layer, which deals with the physical transmission of data over the network medium. These four layers work together to enable communication between devices in a TCP/IP network.
