D-Link DHP-1320: Access Point Router AND

D-Link introduces the D-Link DHP-1320 Wireless-N Router HomePlug AV with a capacity wireless speeds up to 300Mbps. Having dual operating model, this device can be configured either as a router or access point. In the model of the router, D-Link DHP-1320 is connected to a cable or DSL modem to receive and share your broadband Internet connection with multiple computers, gaming device or media player. In the model access point, D-Link DHP-1320 creates a Wi-Fi connections based on existing networks, effectively expanding the network to overcome blind spots.

Types of Network Cable

affect the price of the cable. Computer Cable Networks can be divided into 3 types, namely Twisted Pair Cable, Coaxial Cable and Fiber Optic Cable. You can use one of these cables in accordance with the needs and budget available.

Computer Cable Networks varying types and types

How it Works OSI

Introduction to Model Open Systems Interconnection (OSI)

Model Open Systems Interconnection (OSI) was created by the International Organization for Standardization (ISO) That Provides a structured framework for logic-how processes Interact via a data communications network. Standards were the resource created for the computer industry to Communicate on different networks efficiently.
OSI Layer Model

the workings of TCP / IP

TCP / IP is a data communication protocol model gives a very large change in the world of communications and computers. TCP / IP protocol is to provide an internationally recognized standard and is used as a reference in the development of the computer world, especially on computer networks. Where this protocol can provide flexibility in communication between one computer with other computers in a network even if the computer uses a different operating system platforms. TCP / IP has five layers. Unlike the OSI model has seven layers. The layers include Physical Layer, Network Access Layer, the Internet Layer, Transport Layer and Application Layer. The fifth layer has the functions and responsibilities of each as well as the existing layer in the OSI model.Chapter

Cable coaxcial and HFC Network Infrastructure

HFC stands for Hybrid Fiber Coax.Saat is the use of HFCs in the telecommunications network gets the most attention karenasecara theoretically allows delivery of various services at once (multiservice) sepertitelephony, internet, cable TV and Video on Demand (VOD) with the promise of higher data transmission speeds high and at an affordable price by pemakai.Dalam race to meet keinginanpelanggan (user) will be Internet service faster and cheaper, a factor that plays an important role is the bandwidth. In comparison, the telephone cable network has low bandwidth, so having a low speed while the HFC network provides a very wide bandwidth that offers a higher speed. This shows great potential for the provision of network-owned multimedia services in real time

Connecting TOOLS AND MEASURE OPTIC

Grafting tools (Fusion Splicer) and measuring tools Fiber Optics (OTDR) is one of the supporting devices in the operational management of the access network Fiber Optics
     For the purposes of Operations and Maintenance (O & M) Network Element that operates using a network acccess Fiber Optics, it is a very important role connecting tools and measuring instruments Fiber Optics. Optical Fiber Access Network as a transport medium for broadband and narrowband services are often susceptible to interference, which formed as a fiber optic cable rupture resulting in Transportation End (Perpu) on the supply terminal equipment and data ports. So to help trouble shooting on Fiber Optic network access control can be done immediately, either in the form of search (searching) the location of cable break penyambunganm Fibre Optic Cable.
