Defining Subnets – Brien M. Posey
Subnetting is simply a technique for breaking a big block of IP addresses into smaller blocks that can be used to define separate networks. For example, suppose that you were able to obtain a class B block of IP addresses. Imagine that the address block that you received …
Ports can be readily explained with an analogy:
Think of IP addresses as the street address of a block of flats (apartment complex), and the port number as the number of a particular flat (apartment) within that building.
If a letter (a data packet) is sent to the flats (IP) without a flat number (port number) on it then nobody knows who …

Your first door to the elevator is your gateway. This is all your pc needs to know since the router …
Magic Packet Wake On LAN (WOL)
The Magic Packet is a broadcast frame, transmitted over port 0 (Historically the most common port used), or 7 or 9 (becoming the most common ports used). It can be sent over a variety of connectionless protocols (UDP, IPX) but UDP is most commonly used. The data that is contained in a Magic Packet is …
