The ABC Expansion Co., Ltd. is continuing, and plans are planned to add another office to several floors of the building. The company recommends speed and transmission medium, device compatibility and limitation, IP architecture, pros and cons of VoIP. The company currently has 200 employees and plans to increase to 350 employees next year. There are strict internal staff, and about 70 laptop users frequently travel. The company currently occupies a single-story high-rise office building and plans to add several floors to the office. Commercial grade network cable services throughout commercial establishments include the installation of a series of connectors using unshielded twisted pair (UTP), shielded (foil), unshielded twisted pair (F / UTP), shielded twisted pair (STP) It is included. Connect the hardware and the cable, or connect the multimode or single mode fiber. UTP cables can be used in various grades from call center workshops to telecommunications rooms, data center interior and internal connections. Siemon Augment Category 6 UTP cable uses a larger cable diameter to reduce crosstalk in 10 G BASE - T applications. Available in 5e and 6 categories Twisted pair cable industry standard defines two main types: unshielded twisted pair (UTP) and shielded twisted pair (STP). The latest Ethernet cable uses UTP cable because of its low cost, but the STP cable can be used with other kinds of networks such as FDDI (Fiber Distributed Data Interface). Instead of using an isolated metal wire to transmit the electrical signal, the fiber optic network cable uses a Gallast and an optical pulse. These network cables are made of glass, but you can bend them. These have proven to be extremely useful in the installation of wide area networks (WAN) which require long distance underground or outdoor cable operation and in office buildings with heavy traffic. Unshielded twisted pair (UTP) cable is used in multiple Ethernet networks. Each pair of wires housed inside the lining cable is further rotated to prevent interference with new equipment on the network. Placing this type of cable increases cable consistency and helps reduce network failure. Coaxial cable or coaxial cable is a different common type of network cable. There is a copper conductor in the center, there is a plastic coating used as an insulator between the center conductor and the metal shield. Then protect the cable with a coating. A thick coating provides less shielding and less flexibility

Ethernet is home to processor interactive machines for local area networks. Ethernet was released to IEEE 802.3 in 1980 and 1983. Ethernet has basically replaced competitors' online LAN machines such as Token Ring, FDDI, ARCNET and so on. Ethernet ethics includes wiring and call changes on the OSI physical layer used on Ethernet. Unique 10BASE 5 Ethernet regenerative coaxial cable as aggregate medium. It is kept together with the twisted pair and fiber optic contact along the coaxial cable and is combined with a hub or switch. 25 Gigabit Ethernet is abbreviated as 25 G Ethernet and is standard for Ethernet network connections. 25 G Ethernet was developed by IEEE P 802.3 by the 25 Gb / s Ethernet Task Force and is standard for Ethernet connection. The 25 Gigabit Ethernet Alliance is an open organization that wishes all third parties to participate as members, forwarding Ethernet frames at 25 or 50 gigabits per second (Gbps), and promoting standardization and improvement of applicable product interfaces is. The main functions of 25 G Ethernet are as follows. Gigabit Ethernet is a 3G Ethernet technology with a speed of 1000 Mbps. It is fully compatible with existing Ethernet and promises a seamless transition to high speed. Existing networks can improve performance without modifying existing cables, protocols, or applications. Gigabit Ethernet is expected to fund existing high-speed technologies such as ATM and FDDI. IEEE is developing a Gigabit Ethernet standard that is expected to become available in early 1998. By 1999, it is expected to become a standard for using Gigabit Ethernet with twisted pair. GIGABYTE Ethernet: BN is a very popular choice. The initial standard of IEEE Gigabit Ethernet is the 802.3z standard. Gigabit Ethernet allows data rates of 1,000 Mbps or 1 Gbps. The main advantage of all officially recognized Gigabit Ethernet forms is that each form is built on existing Ethernet protocol standards. That is, the Gigabit Ethernet MAC layer and access method are the same as standard and Fast Ethernet MAC layers and access methods. In addition, Gigabit Ethernet supports half duplex and full duplex communication. Other protocols that may be used in the backbone include Frame Relay (FR) and Asynchronous Transfer Mode (ATM)

The type of UTP Ethernet network cable used to connect the PC to the router using the console. The flip cable is a null modem cable and is most commonly used to connect a PC to the console port as shown in Figure 1 [1]. It likes other types of cables, and their names come from how they are connected. Therefore, because one end of the cable rotates in the opposite direction, it is called a flip cable. Finally, the purpose of this cable is to allow you to configure the connection between the computer terminal and other devices (such as routers and switches) as needed [2]. An Ethernet crossover cable is a twisted pair Ethernet cable that connects computing devices directly, usually through a router such as a network switch, an Ethernet hub, or a network adapter that directly connects two personal computers. Most Ethernet devices currently support Auto MDI - X, so you can use a crossover cable or a straight - through cable. Fiber optic cable consists of a central glass core surrounded by several layers of protective material. Although fiber deployment is more expensive than copper, it provides higher bandwidth and can cover longer distances. There are mainly two kinds of optical fiber cable. Short-range multimode fiber and remote single mode fiber. UTP cables are also the most commonly used cables in computer networks. Modern Ethernet is the most commonly used data network standard using UTP cable. Twisted pairs are relatively low cost compared to optical fibers and coaxial cables, so data networks are widely used for short and medium distance connections. UTP cables are increasingly being used for video mainly for security cameras. Many cameras have UTP outputs with screw terminals, and the bandwidth of the UTP cable has been improved to match the baseband of the TV signal. The telephone line contains hundreds or thousands of pairs. Each bundle contains a twisted pair with a different twist rate. Please carefully choose the twisted pair to minimize crosstalk of large cables. Twisted pair cable industry standard defines two main types: unshielded twisted pair (UTP) and shielded twisted pair (STP). The latest Ethernet cable uses UTP cable because of its low cost, but the STP cable can be used with other kinds of networks such as FDDI (Fiber Distributed Data Interface).

In many countries of the world, companies and educational institutions occupy the majority of society. In these places, you need a way to share and communicate information in business and school. You also need to be able to share business plans and other information with external organizations. The computer was originally intended for personal use only. Due to the importance of sharing data, manufacturers are forced to create technology to connect computers. This is the beginning of the computer network. The Internet has not been found as a prior goal, but to solve the problem of allowing scientists to communicate on a single network in the late 1960's. With this, ARPANET (Advanced Research Institutions Network) funded by the US Department of Defense and the Internet of all smart products were born. Likewise, the Global Positioning System (GPS) was not found to use Google Maps on the iPhone, but rather to solve certain US problems in competition with the Soviet spacecraft at the peak of the Cold War It could be used for military and intelligence purposes. Sputnik In short, both the Internet and GPS are ripple effects from the task. Historically, computer networks can be categorized into topologies, technologies for connecting computers. The most common topology today is a collapsible ring. This is due to the success of the network protocol called Ethernet. The protocol or network language supports the Internet, LAN, and WAN. The star topology is a network design where the central node extends the cable to each computer on the network. In a star type network, computers are independently connected to a network center. If the cable is disconnected, other computers will operate normally. Star topology requires a lot of wiring The network topology is the layout of the interconnected nodes of the computer network or the organization hierarchy. Different network topologies may affect throughput, but reliability is more important. In many technologies such as bus networks, a single failure can cause the network to fail completely. In general, the more interconnections, the more robust the network and the more expensive to install. The physical layout of the nodes in the network may not necessarily reflect the network topology. For example, in FDDI, the network topology is a ring (actually two reverse rotation rings), but since all adjacent connections can be routed through a central physical location, the physical topology is usually a star.
