Jual Cisco Switch Jakarta – If you are someone who likes networks including the internet network, surely you have heard or even already know what is meant by a switch. Switches are often confused with routers, even though these two items are very different items in terms of function and from other aspects.
A network switch (also called a switching hub, bridging hub, and with an IEEE MAC bridge) is a network hardware device that connects devices on a computer network using packet switching to receive and forward data to the destination device.
A network switch is a multiport network bridge that uses MAC addresses to forward data at the data link layer (layer 2) of the OSI model. Some switches can also forward data at the network layer (layer 3) by adding additional routing functionality. Such switches are commonly known as layer-3 switches or multilayer switches.

Selling Cisco Switch Jakarta Understanding Layer
Modern switches use an Ethernet interface. The core function of an Ethernet switch is to provide multiport layer-2 bridging. Many switches also perform operations at other layers. Devices capable of more than just bridging are known as multilayer switches. Switches can study the topology at many layers and pass on one or more layers.
Layer 1 network devices transfer data but do not manage the traffic coming through them, for example Ethernet hubs. Each packet entering the port will be repeated to the output of each port other than the incoming port. Because of this particular, each bit or symbol is repeated as it flows into the Hub repeater and therefore can only acquire and transmit at one speed.
Layer 2 network devices are multiport devices that use hardware domicile, MAC domicile, to process and forward data at the data link layer (layer 2). A switch that operates as a network bridge can link devices in a home or office. Bridge learns the MAC domicile of each connected device.
Layer-3 switches can perform some or all of the functions normally performed by routers. The capability of most network switches is limited to supporting one kind of external network, typically Ethernet, although a router can support multiple external networks on different ports.
Part of the usual layer-3 is IP multicast awareness via IGMP snooping. With this awareness, layer-3 switches can increase efficiency by sending multicast group traffic only to the port where the attached device is already signaling that it wants to listen to the group.
Layer-4 switches can use issues in the transport-layer protocol to make forwarding decisions. In principle it refers to the ability to use source and destination port numbers in TCP and UDP communications to allow, block, and prioritize communications.
Layer-7 switches can distribute payload based on a uniform energy source (URL), or by using some installation-specific techniques to recognize application-level transactions. layer-7 switches can include page caches and participate in content delivery networks (CDNs).
