Components in detailed

NIC:
Network Interface Controller is a computer hardware component that connects a computer to a computer network.
TCP/IP:
The Transmission Control Protocol (TCP), sometimes called the Transfer Control Protocol, is one of the core protocols of the Internet Protocol Suite. TCP is one of the two original components of the suite, complementing the Internet Protocol (IP), and therefore the entire suite is commonly referred to as TCP/IP. TCP provides reliable, ordered delivery of a stream of bytes from a program on one computer to another program on another computer. TCP is the protocol that major Internet applications such as the World Wide Web, email, remote administration and file transfer rely on. Other applications, which do not require reliable data stream service, may use the User Datagram Protocol (UDP), which provides a datagram service that emphasizes reduced latency over reliability.
SWITCH:
A network switch or switching hub is a computer networking device that connects network segments.
The term commonly refers to a multi-port network bridge that processes and routes data at the data link layer (layer 2) of the OSI model. Switches that additionally process data at the network layer (Layer 3) and above are often referred to as Layer 3 switches or multi layer switches.



CABLE:
1.    Fiber Optical – Transfers the date in light speed.
2.    Twisted Pair Cable / Unshielded Twisted Pair Cable
a.     Cat 1
b.    Cat 2
c.     Cat 3
d.    Cat 4
e.    Cat 5
f.       Cat 6
       3.    Coaxial Cable
RJ45 PIN:
RJ45 is a type of registered jack. As a registered jack, telephone RJ45 specifies the physical male and female connectors as well as the pin assignments of the wires in a telephone cable. The original RJ45 uses a special keyed 8P2C modular connector, with pins 5 and 4 wired for tip and ring of a single telephone line and pins 7 and 8 connected to a programming resistor. It is used with a high speed modem.

Basic Components of Network

In this section we learn about the basic components that are required to make a network:

1.    A PC with NIC card (NIC - Network Interface Controller)
2.    TCP/IP
3.    Hub/Switch/Router
4.    Cable
5.    RJ45 Pin





    Network topology design:


    Think of a topology as a network's virtual shape or structure. This shape does not necessarily correspond to the actual physical layout of the devices on the network. For example, the computers on a home LAN may be arranged in a circle in a family room.


    Fully Connected Mesh Topology:
    The value of fully meshed networks is proportional to the exponent of the number of subscribers, assuming that communicating groups of any two endpoints, up to and including all the endpoints, is approximated by Reed's Law.The number of connections in a full mesh = n(n - 1) / 2.The physical fully connected mesh topology is generally too costly and complex for practical networks, although the topology is used when there are only a small number of nodes to be interconnected.

    Star Topology:
    In local area networks with a star topology, each network host is connected to a central hub with a point-to-point connection. All traffic that traverses the network passes through the central hub. The hub acts as a signal repeater. The star topology is considered the easiest topology to design and implement. An advantage of the star topology is the simplicity of adding additional nodes. The primary disadvantage of the star topology is that the hub represents a single point of failure.
    Bus Topology:
    In local area networks where bus topology is used, each node is connected to a single cable. Each computer or server is connected to the single bus cable. A signal from the source travels in both directions to all machines connected on the bus cable until it finds the intended recipient. If the machine address does not match the intended address for the data, the machine ignores the data. Alternatively, if the data does match the machine address, the data is accepted. Since the bus topology consists of only one wire, it is rather inexpensive to implement when compared to other topologies. However, the low cost of implementing the technology is offset by the high cost of managing the network. Additionally, since only one cable is utilized, it can be the single point of failure. If the network cable breaks, the entire network will be down.
    Ring Topology:
    A network topology that is set up in a circular fashion in which data travels around the ring in one direction and each device on the right acts as a repeater to keep the signal strong as it travels. Each device incorporates a receiver for the incoming signal and a transmitter to send the data on to the next device in the ring. The network is dependent on the ability of the signal to travel around the ring.



    Types of Network

    • LAN – Local Area Network – is a computer network that connects computers and devices in a limited geographical area such as home, school, computer laboratory or office building.
    • WLAN – Wireless Local Area Network – links two or more devices using some wireless distribution method (typically spread-spectrum or OFDM radio), and usually providing a connection through an access point to the wider internet. This gives users the mobility to move around within a local coverage area and still be connected to the network. Most modern WLANs are based on the 802.11 (WiFi) standard.
    • WAN – Wide Area Network – is a computer network that covers a broad area (i.e., any network whose communications links cross metropolitan, regional, or national boundaries). This is in contrast withpersonal area networks (PANs), local area networks (LANs), campus area networks (CANs), or metropolitan area networks (MANs) which are usually limited to a room, building, campus or specific metropolitan area (e.g., a city) respectively.
    • MAN – Metropolitan Area Network – a data network designed for a town or city. In terms of geographic breadth, MANs are larger than local-area networks (LANs), but smaller than wide-area networks (WANs). MANs are usually characterized by very high-speed connections using fiber optical cable or other digital media.
    • SAN – Storage Area Network, System Area Network, Server Area Network, or sometimes Small Area Network – is a dedicated storage network that provides access to consolidated, block level storage. SANs primarily are used to make storage devices (such as disk arrays, tape libraries, and optical jukeboxes) accessible to servers so that the devices appear as locally attached to the operating system. 
    • CAN  Campus Area Network, Controller Area Network, or sometimes Cluster Area Network  is a vehicle bus standard designed to allow micro controllers and devices to communicate with each other within a vehicle without a host computer.
    • CAN  is a message-based protocol, designed specifically for automotive applications but now also used in other areas such as industrial automation and medical equipment.
    •  PAN – Personal Area Network – is a computer network used for communication among computer devices, including telephones and personal digital assistants, in proximity to an individual's body. The devices may or may not belong to the person in question. The reach of a PAN is typically a few meters. PANs can be used for communication among the personal devices themselves (intra-personal communication), or for connecting to a higher level network and the Internet
    • DAN – Desk Area Network 

    Introduction of Network

    A computer network, often simply referred to as a network, is a collection of computers and devices interconnected by communications channels that facilitate communications and allows sharing of resources and information among interconnected devices. A computer network is a collection of two or more computers linked together for the purposes of sharing information, resources, among other things. Computer networking or Data Communications is the engineering discipline concerned with computer networks
