what is the diffrent?

Question

whats the diffrent between a server, router, and hub

Answer 1

Server : is an actual computer that stores data, applications or to be accessed by remote or local computers via a network.

Router : is a device that connects independent existing networks

Hub : is a device that connects PCs to a sever.

"Hubs" are not as efficient as "Switches" which actually manages all the connections intelligently in order to maximize performance.

Hubs merely divide the bandwidth equally between all connected PCs even if they are not in use.

A server is an operatig system that you install onto a computer. this operating system gives access to file stored on the computer to users that you create. the most common server operating system is windows server 2000/2003. Linux also has a server version thats free. I could write pages about this, but this is the simplest explination.

A router just gets packets from network A to network B. very simple explination.

A hub is a bit more complicated to explain. first thing you should know is that packets get to thier intend computer one of two ways, either by getting the address of the Network interface card or NIC for sort, or by getting the unique ID of the network address known as an IP address. now a network can be divided up into smaller networks known as subnets. each subnet connects to a router though either a hub or a switch. what happens is that a hub recives a data packet from the router then broadcasts that packet to all the computers connected to it, (a broadcast is like going into a room with 20 people and yelling "I have a package for john smith?" every will hear it, but only one person will get the packet). every computer will get the packet, but only the person it is addressed to will keep it, the other computer will just drop it.

a SERVER is a computer system that provides services to other computing systems—called clients—over a network. The term server can refer to hardware (such as a Sun computer system) or software (such as an RDBMS server).

A ROUTER acts as a junction between two or more networks to transfer data packets among them. A router is different from a switch. A switch connects devices to form a local area network (LAN)

An Ethernet hub or concentrator is a device for connecting multiple twisted pair or fiber optic Ethernet devices together, making them act as a single segment. Hubs work at the physical layer of the OSI model. Hubs are either active or passive. Active hubs repeat the signal received at one port out each of the other ports (but not the original one). The device is thus a form of multiport repeater. Ethernet hubs are also responsible for forwarding a jam signal to all ports if it detects a collision.
