Week 2 - Network Topoligies and an Introduction to Network Cables

     This week, we will discuss network topology and cables. Network topology started with three basic concepts. These topologies can be categorized as partially meshed or fully meshed depending on whether every computer is connected to every other computer. 
    The first topology to discuss is ring. Ring topology is exactly what it sounds like. Computers are set up in a circle, and information flows through a data connection. 
    The next topology is bus. Bus topology runs in a straight line and terminates at both ends. 
    Eventually, the star topology was introduced, offering connectivity benefits by connecting each computer to a central box. With a star topology, if the data connection breaks or becomes disconnected, the rest of the computers on that network would still function. This was a huge benefit, but due to design and compatibility issues, the star topology wasn't very successful until ring and bus concepts were miniaturized and combined into a centralized box. This combination created a hybrid topology resembling a star topology. The hybrid bus topology was not as popular, so the hybrid ring topology now dominates the networking market.
    What connects these networks? Cables connect these networks, and the connection within the network you are making dictates which cable and connection to use. Today's standards for an in-home or business network would call for the use of a Cat6a or Cat7 twisted-pair cable with an RJ45 connector. To make these cables with connectors, one will need strippers, wire cutters, and crimpers, or an all-in-one tool. 
    The norm for cable modem internet connections coming into the network used to be a coaxial cable with an F-type connector, but we have since seen an uprising in fiber and wireless internet service providers. 
    There is so much information on cables and connectors that I urge you to do your own research to determine what is best suited to your needs, or you may join me next week as we go further into the basics of Ethernet.
