    Which protocol is used to issue commands across the public internet?

    Telnet is a protocol used to issue commands across the public internet. It allows users to remotely access and manage devices or systems over a network. With Telnet, users can log in to a remote computer and execute commands as if they were directly connected to it. It provides a text-based interface and is commonly used for tasks such as remote administration, troubleshooting, and network configuration. Telnet operates on port 23 and is widely supported by various operating systems and network devices.

    What is the encrypted version of Telnet?  It issues commands across the internet but the traffic is encrypted.

    Telnet is a protocol used to remotely access and manage devices over a network, but it does not provide encryption for the transmitted data. On the other hand, SSH (Secure Shell) is a cryptographic network protocol that provides secure communication between two systems. It encrypts the data exchanged between the client and server, ensuring confidentiality and integrity. Therefore, SSH is the correct answer as it offers the encrypted version of Telnet, making it a more secure option for remote access and command execution.

    RDP, which stands for Remote Desktop Protocol, is the correct answer for this question. RDP is a protocol that allows users to log into a server remotely across the internet. It enables users to access and control a remote computer or server from a different location. RDP provides a secure and efficient way to establish a remote connection, making it a commonly used protocol for remote server access.

    Which port does DNS use?

    DNS (Domain Name System) uses port 53. The DNS protocol is responsible for translating domain names into IP addresses and vice versa. When a client wants to resolve a domain name, it sends a DNS query to a DNS server using port 53. The server then responds with the corresponding IP address, allowing the client to establish a connection to the desired website or service. Port 53 is specifically assigned for DNS communication, ensuring that DNS queries and responses are properly handled by the correct network services.
