in my first post, I will introduce the types of network hardware and its functions ... Cekidoot :-D
Okay let's look at what the router and functions :
1. ROUTER
Router is a computer, such as other computers, including PCs. Routers have some similarities in hardware and software components that exist within a computer, such as: CPU, RAM, ROM, and the operating system. Router is a network device that operates at the network layer of the OSI model.This router serves as a connecting device between two or more networks to carry data from one network to another. And also the router can split collision domains and broadcast domains . There are a variety of interfaces on the router that is Fast / Gigabit Ethernet, optical, E1, SONET etc.
2. SWITCH
Switch is a network device that operates at the data link layer of the OSI model. But there is also a switch that can operate dilayer network with a specific purpose and are usually referred to as Multi-Layer Switch. Switches are used to expand the network and serves as a liaison multiple end-devices (computers, tablets etc) to form one or several segments of a network / LAN. On Switch also has a variety of interfaces as well as the router is Ethernet, optical, E1, SONET dll.Tapi generally switch has many ports so often called a multi-port bridge.
3. Bridge
Bridge is a network device that also operate in the data link layer of the OSI model. Therefore, how the bridge together with the switch. Bridge can also be used to combine two different network media, as well as between the cable media Unshielded Twisted-Pair (UTP) and fiber-optic cable or two different network architectures. Usually the realization of the bridge is "a particular router or switch" that functioned as a bridge.
4. Access Point
Access Point is a network device that contains a transceiver and an antenna for transmitting and receiving signals to and from remote clients. With access points (AP) wireless clients can quickly and easily connect to the wireless LAN network cables. Access Point sebenarmya introductory course only media like cable function that operates at the physical layer.
5. Server
The server is a computer system that provides a specific kind of service in a network. Server powered by a processor that is both scalable and large RAM, also equipped with a special operating system, which is referred to as the network operating system or network operating system . The server is also running administrative software that controls access to the network and the resources contained therein, as well as file or display devices (printers), and giving access to theworkstation network members.
6. End-Device
End-device is a device that is directly related to the user, for example the device is a PC client, tablet, smartphone, etc.
