A LAN-to-WAN point-to-point connection is also referred to as a serial connection or leased-line connection because the lines are leased from a… Read More »
PPP is an important protocol in the history of networking, particularly for establishing internet connections over serial lines. Its ability to handle multiple network protocols and provide authentication and error detection makes it a versatile and reliable choice for point-to-point communication. Despite the advent of faster and more modern protocols, PPP remains relevant in certain applications, particularly in… Read More »
What is PPP? A point-to-point connection is the most common type of WAN connection. PPP connections are used to connect LANs to service provider WANs and to connect LAN segments within an organization network. A LAN-to-WAN point-to-point connection is also referred to as a serial connection or leased-line connection because the lines are leased from a carrier (usually a telephone company)… Read More »
What is NAT Overload or Port Address Translation PAT.
