A typical network consists of one or more hubs, switches and routers. They all do similar jobs, however hubs are cheaper because all traffic from one port is broadcast across all other ports. They are "dumb".
Switches are more intelligent (and thus more expensive) and will quickly "learn" which IP addresses are connected to which ports. When a message is initially broadcast across all ports for a given IP address, only one port will respond (if at all), and the switch will then associate that port with the IP address for all future messages, reducing congestion across all other ports. This is why whenever a new machine is introduced to the network (or an existing machine goes offline), there is often a "lag" on the network while the switches figure out the new topology.
A router is the same as a switch but it is also programmable; it is really a computer in its own right. Routers typically provide two or more network interfaces allowing two or more otherwise separate networks to be linked. The router acts as the gateway between those networks. Your home broadband router is a typical example, linking your home network (the local area network) to the internet (the wide area network). A side-effect of routers is that a machine outside the LAN cannot initiate communications with a local machine; the local machine must initiate all communications outwith the LAN. As far as the WAN is concerned, only the router is visible, but the router uses network address translation (NAT) to route legitimate communications to the correct local machine. All illegitimate communications are simply ignored. A router typically provides a hardware firewall which can be configured to limit the type of (legitimate) communications that may be permitted either to or from the local area network.
Switches, hubs and routers may be daisy-chained or arranged in a star configuration, or a combination of the two. Each switch is linked to one or more network access points and computers connect to the network via these access points.
Access points can also be made available using Wi-Fi, utilising Wi-Fi extenders or repeaters as necessary to increase the range.
Wired connections are typically achieved using CAT5 or CAT5e cabling (8-core, twisted-pair), however network switches are typically linked via CAT6 or, in some cases, fibre optic cabling.

Which network topology is considered a passive topology because its nodes do nothing to help the data move through the network?
A network topology is the organization of networking devices of a computer on a geographical basis. In essence, the different points/nodes in which various computers are connected or linked together constitute a topology. Several computers are being connected to a certain link. There exists more than one link and they form a topology for more information visit our website: The assignment helpline
Can a network be as small as two computers linked together for the purpose of sharing information?
Yes, that's exactly what a network is. Two or MORE computers linked together.
What is Computers to which other computers connect called?
A Server Depends on the network topology (design). Is the topology a token-ring, star, bus, etc? Server is usually the correct answer in general, but you also have switches, routers, and on older networks, hubs. Some old networks didn't use servers at all. All of the computers combined made up the "server" so to speak as they were all directly linked to one another such as in a bus topology. The problem with bus is that if on computer goes down, the entire network goes down.
What does it mean for 2 computers to be networked?
Computer networking allows 2 or more computers to share information. The two computers are either linked to each other directly through a crossover network cable (peer-to-peer network), or through one or more intermediate hubs, switches and/or routers. Wireless routers allow 2 or more computers to network without being physically wired to the network.
When only a few microcomputers are to be linked then the bus network is typically used?
Bus topology LANs are very rare these days. It would be easier to use a star topology than a bus topology for a few devices.
A system of computers and peripherals that are linked together is called?
Network.
What Is a group of computers linked by wired or wireless technology?
Network
