When computer networks work well, we expect that most operating system's internal modules are transparent to the average user. To components more common in a computer network, not including cables, are the routers, "centers" and "switches". Many of these modules Each may be similar cosmetically. general assembly has Ethernet jacks (RJ45, which resembles a phone jack large) and LED indicators. However, these modules work differently, and it is important to understand the differences.
The operation of modern equipment in the interconnection network "system open (OSI) standard. This standard defines how communications in a network must be implemented. By adhering to this standard, the modules from different manufacturers can coexist on the same network. wireless networks (WiFi) standard 802.11X are a subset of additional network systems.
When a message is sent to a computer, is divided into parts. In The basic message is reduced to "1" and "0" bits. The next level is a group of bits called a "framework".  A chart contains the control information, including the destination address and error detection. The next level is a group of executives called a "package".  The basic terms and packages are sometimes used interchangeably. If a message is sent on a complex network like the Internet, some packets may take a different path, and are recombined at the destination.
Error detection is used for routine packets. frameworks and most common is called "Checking cyclical redundancy check (CRC). CRC are all "1" in the frame or packet. This number is stored as a hexadecimal value in the final of the frame / A On packet. the receiving end, the process is repeated. If the two hexadecimal values agree, the trial passes. If not, the receiving device requests the sending device resend. most of this functionality is performed by integrated circuits (chips) inside the network modules.
The Hub
The network hub runs in the first layer of the OSI standard, called layer "physical".  The center is the simplest of the three modules. A center is not knowledge of the message content is generated, she manages just bits. message records the signal and broadcast to all, especially for the port that sent the message.id "active" noise cleaned center of the electrical signal and amplify the signal before rebroadcast. center "person not amplify signal, only receive the signal, and retransmit the signal received at each port. Hubs are sometimes used to establish multiple connections of computers with a printer.
Network Switch
The network switch works on the second layer of the OSI standard, called "data link layer.  The network switch, as its name suggests, the switch routes the signal, so that a message goes to a specific destination. A switch improve network performance, including networks with many computers. A switch has enough intelligence to remember the path to each network switch destination. manages a frames. message
When you connect a computer to a network switch, the switch stores the Media Access Control or "Maca" address of the NIC of the computer (NIC).  This is called the protocol address, or "ARP". A When a frame is received by a specific computer, switch sends the only framework that computer.es Al prevent the rail network to be used for all images, network resources are conserved. computer A can send a frame to computer B, and at the same time, the team C is sending a team framework for D.
Network Router
The network router works on the third layer of the standard OSI layer called the "Red". A name of a router is also indicative of their routers role. have some of the same capabilities as switches, routers, but are most often used to connect two or more networks. For example, a router can be used to connect a wireless network using a conventional network (LAN). Another use is common to connect a LAN to the Internet (network wide "zone" or "WAN").  In this role, the router uses Network Address Translation (NAT) so that all computers connected to the local network can share a single IP router handles address. A message packets. A router uses IP addresses in packets routing between multiple networks.
A personal computer can be configured to manage the function of a router, if equipped with a router and software two or more network interface cards (NIC). Â a separate card is needed for each network.
A router is capable of advanced functions such as serving as host (DHCP domain control) server and Firewall. A firewall protects computers against the potential hazards of other teams were CNRS multiple network. networks often requires the conversion of protocols.Â
A router is a router diverse classification. May provide connectivity within the service between sites, and between business and the Internet. The network router with the largest Internet service providers are used in very important business networks, or contact a company with a satellite link to remote routers locale. advanced businesses are powerful computers with microprocessors. Routers are used by sophisticated the Internet to manage network traffic more efficiently.Â
A router maintains a table called "base routing information (RIB) that stores information about available routes. The rib can be static (manually determined by a network administrator) or dynamic (continually updated on the basis of changing conditions). A rib is simple in a small LAN, but can be extremely complex in the very large routers that are used on the Internet.
Abstract
There are more types of network modules that the three discussed here, and there may be significant overlap in roles. For example, a hub, "smart" can have many characteristics of a wireless network switch. network (WAN) have much in common with their cousins in conventional LAN, but the additional protocol is added to the special security concerns and specific functions of multiple wireless interference can be combined networks. in a single network routers assembly. times sub-assemblies that function as networks switches.Â
