Computer Networking

The basic concept of computer networking is having two or more computers connected together sharing information. The information shared can be files, printers, and programs. The size of a computer network largely depends on the user’s needs. If you are building a home network, then you will likely have one to three computers networked. In a large office, you may have as many as 100 or 200 computers networked together.

Types of Networks
There are different ways to perform computer networking. Wireless networks, or WLAN/WWAN, uses wireless technology to network computers together. This type of computer networking is becoming more popular for the home user. Using a router and a host computer, you can connect multiple computers in your house to the network. If one of those is a laptop, it’s possible to take that computer from room to room as you work. Local area networks, or LAN, are smaller networked areas. Local area networks usually have higher data transfer rates, and do not require special telecommunications services. Wide area networks, or WAN, connects a large group of computers together. These networks are typically designed for one organization’s use. Metropolitan area networks, or MAN, are networks that usually span the size of a city. They use fiber optic cables and are usually wireless. ATMs use metropolitan computer networking.

The OSI model, or Open Systems Interconnection Reference Model, is a type of computer networking that uses layered communication. The seven layers are arranged from bottom to top as: physical, data-link, network, transport, session, presentation, and application. The OSI Model was too complicated to be useful in today’s computer world. Even so, it is still often referenced by IT professionals when they are describing computer networking or network applications.

By setting up a computer network at home, or in your office, you can give multiple users access to files on the host computer. It’s also possible to have users able to share files between their computers. Printers and programs can also be shared among users on a computer network.

This is just a small view into the world of computer networking. Setting up a computer network in your home has never been easier. Today’s technology makes it possible with just a few simple steps.

Computer Networking – A Brief Introduction

Data communications and computer networking is a very significant part of data technology. Today, all businesses in the world desires a computer communications mesh works well, very fast and flexible get access to to data. Imagine no connection scheme at universities, clinics, informative organisations and multinational associations, the dispute is to broadcast with each other. In this item you will discover the straightforward recount of a computer network. The reason of this item is persons who desire the connection mesh of information, measures and networks.

Connecting to the mesh gear and components. For exchange of data and assets between two or more computers in the mesh is known. There are distinct kinds of computer systems for example LAN, MAN, WAN and wireless networks. The major flats are engaged, the infrastructure of a computer center, swap, router and modem, get access to issue and mesh business card and mesh cable.

LAN entails localized locality mesh and a mesh in a room in a construction or on a mesh of a little locality called “LAN. Man is for the Metropolitan Area Network and encompasses the mesh between two agencies in the city. WAN Network wide locality and manage not realise the attachment between two computers or more between the two towns and two nations and continents.

There are distinct topologies of computer networks. A personal topology characterises conceive or the conceive of a network. These topologies are celebrity topology, coach topology, mesh topology, celebrity topology, coach, etc. attached in a celebrity topology, each computer exactly into a mesh to a centered hub or swap, as we understand it. If all the computers in a celebrity topology is not awkward leverage on other computers on a network.

There are distinct measures and apparatus on your network. The most widespread benchmark for Ethernet LAN. key apparatus in a computer mesh is a hub, swap, router, modem and get access to issue, router, etc. These are two distinct mesh attachments, ordered and physical. All communications on the Internet is founded on the router. Hub / swap to the computers on the mesh can use.

How To Manage A Computer Network

Today it is almost inconceivable for a company that do not have computers or a building or a high-tech company. If a company more than one computer, usually are linked in a LAN. These networks may be more or less sophisticated and cheaper or more expensive. Companies invest a lot (both in terms of time and money) on a local network, as there are many benefits that a local network, a business meeting and how it should be administered.

Some companies use a local network, so they depend heavily on the job forever. If the failure of the corporate network, you can see all the people talking in the hallways because they cannot do their job. This means that large losses for the company and creates risks to workers. All companies should consider their local networks, an important advantage and downtime must be avoided. This places high demands on the network of staff in these networks of approximately 100% of the clock is ticking.

The benefits of network management software
An important advantage of the installation and maintenance of LANs is the opportunity to improve communication and collaboration between employees and customers to create.

Security considerations: security of local area network can be an obstacle for aid and suffer. global security is an advantage, as it provides a central strategy for improving access and the safe handling and disaster. All information will be protected in the design and implementation of network security solution. In addition, networks of computers in the network create a security risk, and that makes it technically possible for someone too many computers on the network once access.

Economic considerations: the installation of a LAN is a relatively expensive project. Servers, cabling, switches, routers and software can be expensive and cannot be purchased without professional advice. Continued use of the secure network, and resource intensive and can be expensive.

Surprisingly, a LAN has a number of cost savings. Share resources avoid the need to buy for each device. Even more important is the security offered by the Internet. Data loss can be costly for society and in some cases, the chief of the cases to a complete stop. Network Equipment Administration should require a consistent routine data backup with regular checks on the quality of data – a practice that company huge sums of money in case of failure will save.

Computer network management: preliminary analysis of phase
The first phase of the computer network management is the source of the problem of identification (a preliminary study various options for different sizes can be considered useful) and the definition of the requirements. Examples of what is necessary to assess other network operating systems, messaging systems and other applications. The choice of hardware should also be considered. This is usually to define what the system should do, not what we should aspire to.

Computer network management: Design

The design objective is to determine how the requirements of the specification requirements. The current approach is too large and complex projects, which is broken into smaller, more manageable subprojects.

Computer network management: The Implementation phase

This phase includes the physical installation of the LAN. The cable is passed, it installs the software and computers and other equipment are created.

Network Computer Management: Integration and System Test

In this phase, the implementation of the network starts and routines adapted to the users and operators. The system should be tested, both to ensure the system meets the requirements of the specification and sufficiently stable for the central role of the organization.

Network Computer Management: Operation and Maintenance

Local networks are complex operating system routines. That is because it can have serious consequences in case of malfunction or unauthorized access of people to the system. Many companies have the care of employees is dedicated exclusively to the implementation and maintenance of computer networks, to drink.

Network Computer Management: Tools
Although the organization cannot be managers must also monitor the network for more than eight hours a day. In fact, some of the worst problems that can occur with nets during the night, when nobody can do in the network. With network management tools of quality, the organization can be sure that problems will be given to prevention and clean – and your network administrator for a moment the notice shall be served as an extraordinary error.
