Wired / Wireless Network and Set Up

Wired Networks:

Wired Network Topologies:

Each computer on the network is connected to the other computers with cable (or some other medium, such as wireless using radio frequency signals). The physical arrangement of the cables connecting computers on a network is called the network topology.


The three basic topologies used in computer networks have been as follows:


  • BusConnects each computer on a network directly to the next computer in a linear fashion. The network connection starts at the server and ends at the last computer in the network. (Obsolete.)
  • StarConnects each computer on the network to a central access point.
  • RingConnects each computer to the others in a loop or ring. (Obsolete.)

The following table summarizes the relationships between network types and topologies.


Network Cable Types and Topologies
Network Type Standard Thin (RG-58) coaxial Topology
Ethernet 10BASE-2 Thin (RG-58) coaxial Bus
10BASE-5 Thick coaxial Bus
10BASE-T Cat 3 UTP or better Star
Fast Ethernet 100BASE-TX Cat 5 UTP or better Star
Gigabit Ethernet 1000BASE-TX Cat 5 UTP or better Star
1000BASE-TX Cat 6a UTP or better Star
Token-Ring (All) UTP or STP Logical ring

The busstar, and ring topologies are discussed in the following sections. Wireless networking, which technically doesn’t have a physical topology as described here, does still employ two logical (virtual) topologies, which I discuss as well.


Bus Topology


The earliest type of network topology was the bus topology, which uses a single cable to connect all the computers in the network to each other, as shown in the image below. This network topology was adopted initially because running a single cable past all the computers in the network is easier and uses less wiring than other topologies. Because early bus topology networks used bulky coaxial cables, these factors were important advantages. Both 10BASE-5 (thick) and 10BASE-2 (thin) Ethernet networks are based on the bus topology.



However, the advent of cheaper and more compact unshielded twisted-pair cabling, which also supports faster networks, has made the disadvantages of a bus topology apparent. If one computer or cable connection malfunctions, it can cause all the stations beyond it on the bus to lose their network connections. Thick Ethernet (10BASE-5) networks often failed because the vampire tap connecting the AUI device to the coaxial cable came loose. In addition, the T-adapters and terminating resistors on a 10BASE-2 Thin Ethernet network could come loose or be removed by the user, causing all or part of the network to fail. Another drawback of Thin Ethernet (10BASE-2) networks was that adding a new computer to the network between existing computers might require replacement of the existing network cable between the computers with shorter segments to connect to the new computer’s network card and T-adapter, thus creating downtime for users on that segment of the network.


Ring Topology


Another topology often listed in discussions of this type is a ring, in which each workstation is connected to the next and the last workstation is connected to the first again (essentially a bus topology with the two ends connected). Two major network types use the ring topology:


  • Fiber Distributed Data Interface (FDDI)—A network topology used for large, high-speed networks using fiber-optic cables in a physical ring topology
  • Token-Ring—Uses a logical ring topology

A Token-Ring network resembles a 10BASE-T or 10/100 Ethernet network at first glance because both networks use a central connecting device and a physical star topology. Where is the “ring” in Token-Ring?


The ring exists only within the device that connects the computers, which is called a multistation access unit (MSAU) on a Token-Ring network (see the following image).



Signals generated from one computer travel to the MSAU, are sent out to the next computer, and then go back to the MSAU again. The data is then passed to each system in turn until it arrives back at the computer that originated it, where it is removed from the network. Therefore, although the physical wiring topology is a star, the data path is theoretically a ring. This is called a logical ring.


A logical ring that Token-Ring networks use is preferable to a physical ring network topology because it affords a greater degree of fault tolerance. As on a bus network, a cable break anywhere in a physical ring network topology, such as FDDI, affects the entire network. FDDI networks use two physical rings to provide a backup in case one ring fails. By contrast, on a Token-Ring network, the MSAU can effectively remove a malfunctioning computer from the logical ring, enabling the rest of the network to function normally.


Star Topology


By far the most popular type of topology in use today has separate cables to connect each computer to acentral wiring nexus, often called a switch or hub. The following figure shows this arrangement, which is called a star topology.



Because each computer uses a separate cable, the failure of a network connection affects only the single machine involved. The other computers can continue to function normally. Bus cabling schemes use less cable than the star but are harder to diagnose or bypass when problems occur. At this time, Fast Ethernet and gigabit Ethernet in a star topology are the most commonly implemented types of wired LAN.

What is Wireless Network and how to setup?

Wireless Network is the computer network which is not connect through any cables. Due to this one can avoid costly process of cabling for homes, telecommunication networks and business installations or connection between two pieces of equipment at various locations  Wireless Networks are generally implemented and administered through transmission system called radio waves.

Various types of Wireless Networks

  1. Wireless PAN

    Wireless PAN means Wireless Personal Area Network which are interconnected within small relative areas. For example, Bluetooth or infrared lights use for interconnecting a headset to a laptop.

  2. Wireless LAN

    Wireless LAN is Wireless Local Area Network which use to connect two or more devices on short limited distance using wireless distribution process. Due to wireless, this is possible through spread-spectrum means a technique by which signals generated in a particular bandwidth is spread in the domain. This allows users to move around within local coverage area and still remain connected to the network.

  3. Wireless mesh network

    A wireless mesh network made up of radio nodes organized in mesh technology  Mesh topology means including related links, information, and terms. It is a local area network that provides one of two connection arrangements, either full mesh topology or partial. Each node passes messages on behalf of the other nodes. Mesh networks can “self heal”, automatically re-routing around a node that has lost power.

  4. Wireless MAN

    Wireless Metropolitan Area Networks are a type of wireless networks that connects other several wireless LANs.

  5. Wireless WAN

    Wireless Wide Area Networks are wireless networks that cover large ares such as between towns and cities, or city and suburb. These networks can be used to connect branch offices or as a public internet access system. The wireless connections between access points are done using point to point microwave links through parabolic dishes on the 2.4 GHz band.

  6. Setting Up Wireless Network

    You can easily set up your wireless network at you home using the wireless configuration feature in Windows XP. For that your computer need to install wireless network card if not found already. If wireless network card is already installed on your computer you need to run provide software to configure the network.
