Sample text

Some protocols would be slowed down or otherwise inhibited by all of the overhead that TCP uses for those services, so UDP doesn’t care about establishing a connection, error checking, data loss, sequencing, or any of the other overhead stuff its brother protocol at the transport layer is concerned with. UDP does its job and doesn’t bother to verify that the traffic made it to the destination. UDP is used for a lot of streaming connections, such as video and audio, and for connecting where the sending application doesn’t care whether or not the receiver gets every single bit of data.

Generally, a host is anything such as a computer, server, network device, or wireless device that processes data. A network host has a network card that is connected and sends and receives network traffic (and may also be called a network node), whereas a standalone host may not have a network connection. Decentralized vs. Centralized Networks You also may need to know about the concept of centralized networks versus decentralized ones. A decentralized network is one where all connected hosts are considered equal, and have their own security requirements, usernames, passwords, resources, and so on.

You have to learn some things before others in order to have a good foundation of knowledge so that you can understand the more complex topics that come later. So this chapter is about learning some of the fundamental (and very important) concepts involved with networking. Mobile devices still rely on the basic networking technologies in order to connect to each other and the Internet, transfer data, and download the cool videos and other content we’ve come to expect. CompTIA recommends that you have taken their Network+ certification exam and have at least 18 months experience working with mobile devices, networking, and other related technologies before sitting for the Mobility+ exam.
