This concept was commercially adopted by most of computer users, Institutions, schools, IT departments within the decay and networking of computers got very popular compulsion on the broader scale computers networking is collection of multiple computers, printers, scanners and other devices to communicate and share information share files and software etc. This cannot be possible without the concept of networking; networks have made lives easier for many people in their professions. One can command the computer to print the document out without even sitting on it. Computers are everywhere now it is the must have machine in every field of profession. If you have more than one computer at your place having it networked is as important and useful as having computer itself.
In this section of tutorials and articles we will teach you what computer networks are, what are computer network types?
Which network type is best used for which approach, hardware requirement, advantages, software requirement, and computer network security? There are as many as eight types with which computer networks can be formed. Computer Network types Local Area Network (LAN) is technical name for computer networks which is normally developed among a single house and office etc. Immense work is done on networking by networking device manufacturers and it is still going on, every now and then there is new and better solution to network multiple computers.
LAN is been implemented and been replaced by WLAN already, WLAN is wireless local area network which performs same function as LAN does but wirelessly. LAN however is still used and understanding it is very important before moving to better and enhance solutions. Browse through the navigation towards your left which will help you understand the entire concept involving deployment of computer networks and that should be able to help you build your very own local area network.
Wide Area Network, (WAN) Wide area network is communication among computers which are located far from each other. Internet is one classic example of WAN, It is the collection of large number of computers connecting together to share information with each other and accessible from everywhere.
Metropolitan Area Network (MAN) Man is not used as commonly as WAN and LAN networks are, it posses its importance when it comes to connect two offices or organization remotely located together to build networks among computing systems. It covers large area but not as much as WAN is capable of.
This page contains very basic information on computer networking. However we have tried our best to provide you all relevant articles on computer networking with which it should be easy to form computer networks without additional help. You can go through different articles on left menu, follow the steps and you should be able to sticks hands to forming computer network communication design in which the physical components of computers are arranged in a sequence so that they can communicate with each other. Network is a combination of hosts, applications, routers, hardware, software and links of media. Network architecture is a guideline and technology for designing building and managing a network.
Purpose of Network Architecture
The purpose of network architecture is to provide assistance and guidance to implement high quality network. The network architecture not only helps you to deploy the network but also assists you in troubleshoot and maintaining architecture. Network architecture also helps you security management and disaster recovery.
Network architecture is composed of many layers. In the process of layering the communication tasks are divided into smaller parts, each part is further divided into sub tasks for accomplishing tasks. These subtasks interact with the other communication processes. The process of layering keeps the network design simple. There are many ways to design and set network architecture.
There are many choices available to set up a network however every network must have three basic parts like network users, applications and devices. Network itself is operating at physical layer of the OSI model. The devices are operating mostly at data link layer or network layer. The application exists at the session layer of the OSI model. Lastly the user is at the last two layers of the model including presentation and application layer.
The Network Topologies
The network topologies play an important role in the formation of a network. Network architecture designs closely related to design of the network topology. There are many types of network topologies like star topology, bus topology, ring topology, mesh and tree topology. The choice of network topology is dependent upon the type and size of network architecture. Most commonly used network topology is mesh. However the application of topology depends upon the amount of space in which one has to establish network architecture. The network architecture which comprises of ten to twelve computers mostly is designed on using bus topology as a network. In a bus topology an array of computer terminals is connected to one after the other computer and a network is established. In order to establish larger networks Mesh topology is used. Mesh network architecture is a complex design and it involves the redundancy of interconnections attached to the routers and switches in a network.
Components of Network Architecture
There are six basic network architecture components such as servers, proxies, clients, command consoles, server modules and cores. The server is the backbone of any network. The role of servers in network architecture is to communicate with proxies and other peered servers. They are at the top layer of the network and they do not communicate directly with client. Moreover servers receive complete projects and tasks .proxies can be termed as the focal point of the network because it facilitates the communication of the devices. Proxies usually perform buffering and they also communicate with the others of its type to share the loads of the network.
The client systems are the workers of the network. They receive tasks, they interact with the users and they perform user applications. Command consoles are the network guidelines which provide assistance to users about how to control the authorize network nodes. The core is the real work done in the system. The cores are verified within the network and with the clients to prevent bad cores. Server modules handle the particular tasks of the server. Server module is generally registered with the server libraries; this would help the server to perform the needed task.
