OSI Seven Layers in the Networking World

Seven OSI Layer - In the world there is a term with osi network layer, layer osi seven parts. There was the seventh osi layer, is

1. Physical is the lowest layer in the OSI model. Serves to define the network transmission media, signaling method, synchronization bits, network architecture (such as Ethernet or Token Ring), network topology and wiring.

LAN | Local Area Network

At this time I will posting about the definition of a network that this time I learned about in school, that is, a local area network or LAN is a computer network that connects computers and devices in a limited geographical area such as homes, schools, computer labs or office buildings. Defining characteristics of LANs, in contrast to the wide area network WAN networks, including those usually higher data transfer rates, smaller geographic areas, and lack of need for channel

Definition VSAT

VSAT, These words are not foreign to the ears of a network among experts, is singakatan of VSAT Very Small Aperture Terminal is a great option for people who are in remote areas and in desperate need of internet connection where no other infrastructure such as ADSL, ISDN, etc.. even the telephone.

VSAT dish itself is shaped like a large-sized sanagt and directly facing the sky. With this equipment the digital signal is received and sent to the satellite. Satellite signal itself serves as a successor to be sent to another point on earth.

Definition of Metropolitan Area Network

Metropolitan area network or shortened by MAN. A network in a city with high-speed data transfer, which connects various locations such as campuses, offices, government, and so on. MAN network is a composite of several LANs. Coverage of this MAN among 10 to 50 km, MAN is a network that tepaMetropolitan area network or shortened by MAN.

Definition of Wide Area Network

WAN is short for the term information technology in English: Wide Area Network is a computer network covering a large area as an example of a computer network between regions, cities or even countries, or can be defined as well as computer networks require routers and public communication channels.

Understanding Local Area Network

Commonly abbreviated as Local Area Network LAN is a computer network whose network covers only a small area, such as campus computer networks, buildings, offices, in homes, schools or smaller. Currently, most LANs based on IEEE 802.3 Ethernet technologies using a switch device, which has a data transfer speed 10, 100, or 1000 Mbit / s. In addition to Ethernet technology, the current 802.11b technology (or so-called Wi-fi) is also often used to form a LAN. Places that provide a LAN connection with a technology called Wi-Fi hotspots.
