They create systems for automobiles, robotics, aircraft, or power generation for an entire city. Engineers are required to be licensed, which can be achieved by completing a bachelor's or master's degree in electrical engineering and taking an examination.
In network addressing, the host address, or the host ID portion of an IP address, is the portion of the address used to identify hosts (any device requiring a Network Interface Card, such as a PC or networked printer) on the network.
Because address allotted to the network ID varies, depending on the address. Most IP addresses fall into the following address classes: Class A addresses: The first 8 bits of the IP address are used for the network ID. The final 24 bits are used for the host ID. Class B addresses: The first 16 bits of the IP address are used for the network ID. The final 16 bits are for the host ID. Class C addresses: The first 24 bits of the IP address are used for the network ID. The final 8 bits are for the host ID. Address Class and Network Type. More bits lead to more combinations.
