It is light weight‚ easy to install‚ inexpensive and support many different types of network. It also supports the speed of 100 mps. Fiber Optics Fiber optic cable uses electrical signals to transmit data. It uses light. In fiber optic cable light only moves in one direction for two way communication to take place a second connection

replaced competing wired LAN technologies such as a token. The Ethernet standards comprise several wiring and signalling variants of the OSI physical layer in use with Ethernet. The original Ethernet used coaxial cable as a shared medium. Later the coaxial cables were replaced with twisted pair and fibre optic links in conjunction with hubs or switches. Data rates were periodically increased from the original 10 megabits per second to 100 gigabits per second. In simple terms‚ Ethernet is a system

Router functions focus on “Layer Three”. User workstations and servers are often identified with “Layer Seven”. HUB Hub is a hardware device that contains multiple‚ independent ports that match the cable type of the network. Most common hubs interconnect Category 3 or 5 twisted-pair cable with RJ-45 ends‚ although Coax BNC and Fiber Optic BNC hubs also exist. Ethernet Hubs An Ethernet hub is also called a multiport repeater. A repeater is a device that amplifies a signal as it passes through

As explained in the proposal the proposed upgrade from a peer-to-peer network architecture to client/server was an imminent necessity. Cable Recommendation The accounting firm presented with the possibility of moving to a newly constructed office site. The best time to make changes to any network architecture is when planning to deconstruct in one location and start anew in another

This is the standard Ethernet connector for most systems used today. I would first measure out the length of cable that I would need. I would then use a wire cutter to cut the length that I need‚ leaving enough room for corrections and to open the wire. I would then use wire strippers to remove a small piece of the outer most jacket. I would then choose
