Study Notes
Remote Login Protocols
- SSH (Secure Shell) is considered more secure for remote login due to its encryption and secure authentication mechanisms.
Telnet
- Telnet typically connects to port 23.
- To "telnet" means to remotely login to a computer or network device.
TCP/IP Protocol Suite
- The top layer of the TCP/IP protocol suite is the Application layer.
SSH vs Telnet
- SSH is preferred over Telnet for remote login due to SSH's encryption and secure authentication, whereas Telnet transmits data in plain text.
MAC Addresses
- A MAC (Media Access Control) address is 48 bits or 6 bytes long.
- MAC addresses operate at the Data Link layer (Layer 2) of the OSI model.
Address Resolution Protocol (ARP)
- The purpose of ARP is to resolve IP addresses to MAC addresses.
Networking Terminology
- NIC stands for Network Interface Card in the context of networking.
MAC Address Types
- Multicast MAC addresses are used for one-to-many communication.
