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.

DM500 is a useful and powerful satellite TV signal receiver produced by Dream Multimedia. DM500 has a LINUX operating system, if we want to expand it usage; we have to connect it to our computer. Connecting DM500 to computer will make the edit of the channel menu according to our demand more easily. It will also reduce a lot of time if we use the RJ 45 ports to rewrite or upgrade the operating system of DM500. Using the serials port will consume 10 minutes while the unshielded twist pair will reduce more than 8 minutes. The links between DM500 and computer will also make the upload of our accounts information possible. So, it is the basic knowledge that all the fans of satellite signal receivers should have.

Before we get to operate the two devices together, we shall know the network settings of Dreambox first. We can get into the network setting interface though the way of Main Menu Settings Advanced Settings Network Settings. We will see the network information of Dreambox in the interface. We have to pay attention to the DHCP settings. If the DHCP is tick marked, it means that DM500 will get the IP automatically. If not, we have to mark the tick ourselves.

There are two ways of connecting the two devices.
1.#Connect though a router. This is the easiest method. If we use a router, we can set a LAN. There will be the method of setting up a LAN in the guide of router. The router will set up a LAN includes DM500 automatically if the option of DHCP is tick marked. The DM500 will get the IP distributed by router automatically and get into LAN. Then the computer can operate on Dreambox though LAN. If you want to upgrade or rewrite the operating system, you have to read the instruction of DM500.
2.#Using the Crossover Ethernet Cable. We can connect Dreambox and computer using the crossover Ethernet cable. The crossover Ethernet cable is not the Ethernet cable we usually use to connect internet. It is sold in shops, but we can also make one by ourselves. When we connect the both, we have to set the network parameters on computer and Dreambox. Now you should not mark the DHCP and set the IP of both devices to 192. 168. 1. 2. Then the both devices are connected.

A common ancillary service in Chicago that is found in many homes is a home computer network. Home computer networks have changed very much over the last few years; this is a result in most cases to a drop in the price of hardware that is required to support the network and the ease of which it can be set up. Home networks have proliferated as a result of the increase in laptop computers or amore recently smart phones and tablets. There are currently four types of home networks; wireless, personal area network, LAN and VPN, virtual private network.

Perhaps the most common ancillary service in Chicago that suppliers and installers are asked to get involved in is wireless networks. With internet service available in almost every home in the country, all it takes is a wireless router and wireless LAN connections in every device that wants to be connected to the network. The task of the wireless router is to distribute the incoming signal to every device upon demand. This means that in a typical wireless home network all users can connect to each other as well as the internet, they can share printers, scanners and other peripherals that not long ago were needed at every workstation.

A personal area network is very much the same as a wireless system but the devices are connected by hard wiring. A typical installation will see the addition of network outlets to the home telephone system. This arrangement allows everyone in the home to connect to the network through the use of an Ethernet cable which is cables that are designed to transmit lots of data at very high speeds.

A LAN, local area network is a very popular method of setting up a home based business where complex computer technology and processing power is needed. A typical LAN uses a powerful central computer known as a server; it is the server that is used to store large amounts of data as well as acting as the central repository for applications which are needed to run the business. In this arrangement, work stations that are available to employees are actually directly connected to and dependent on the central server.

The reason for the installation of a home network as an ancillary service in Chicago is simplicity. It becomes easy to share files, printers and gain access to the internet, the overall cost of home computing has been brought well into the realm of possibility for most families.

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.

It’s probably safe to say that modern business is dependent on electronic communication and computer communication. Ask any person who works in a corporate environment how many e-mails they receive and send in a day or how many times they need to print a document, and the number you will hear will probably be quite large. Thus, one essential thing to have in any modern office is a reliable computer network. A computer network is a group of computers and machines that are linked together through one of a variety of different methods in order to share, transfer, and communicate information.

A computer network typically includes computers, printers, and fax machines, but they can also include any type of machine or device that’s linked in. A slow and unreliable computer network means that the computers and machines cannot communicate, which means that people can’t communicate with each other, which directly translates to poorer work productivity, not to mention frustration and annoyance.

But before you know how to find a reliable computer network or how to improve your existing one, it’s helpful to know about the many different types of networks and their capabilities:

Local Area Network

One type of network is called a LAN (Local Area Network). A LAN is one of the major two types of computer networks and is most likely found in homes or small offices as it covers smaller physical areas than other types of networks. It’s a computer network that typically connects computers to word processors and other office equipment. Although a LAN covers only a limited area, it can connect a large number of computers and electronic equipment. For instance, schools and airports are two types of large, centrally-located organizations that often use a LAN. And the fact that it covers a specific, small geographic area means that the network doesn’t require leased telecommunication lines. Perhaps the most crucial defining characteristic of a LAN is its high data transfer rates. Because the network is serving a limited area, data can move from device to device much more quickly.

Wide Area Network

Essentially the opposite of a local area network is a WAN (Wide Area Network). This type of network is the second major type of computer networks available, and unlike a LAN, a WAN covers a wide geographic area. Whether you need to connect computers across the country or across the globe, a WAN is a good solution. As opposed to a LAN, a WAN is not confined to a network within a specific building. And the most popular type of wide area networks is the Internet. And both the LAN and WAN come with wireless options, meaning that computers and other machines can be connected without using cables.

Internetwork

Internetwork is another category of computer networks that overlaps with both land area networks and wide area networks. Basically, an internetwork uses routing technology to connect two or more different computer networks. In other words, an internetwork connects to LANs or two WANs. An internetwork connects communication between or among public, private, commercial, industrial, or governmental networks. Within the internetwork category, there are three different types of networks: intranet, extranet, and internet. The difference among these networks is dependent on who administers the network and who participates in them.

Intranet

The intranet uses something called the Internet Protocol (IP) and related tools, including web browsers and file transfer applications. Internet Protocol assures that any packet of information sent from one computer or device arrives at its destination safely and in the same condition when it was sent. IP does this by assigning a unique address, a number, to each device connected to the network. The intranet is controlled by a single administrative entity. The administration’s specific responsibility is to ensure that the network is closed to all unauthorized users and those outside the network. In most cases, the intranet is used within a single organization.

Extranet

An extranet must have at least one connection to an external network to be considered an extranet. It is a network that only services a single organization, but that usually connects to networks of trusted organizations. For instance, a business organization may allow their network to connect to a network of customers or suppliers. In other terms, the extranet is usually a network that includes extraneous connections from an intranet.

Internet

The Internet is the most popular type of internetwork that allows interconnection and intercommunication across worldwide networks. The Internet can connect a variety of different networks, including governmental, academic, public, and private networks. Most people are familiar with this internetwork, as the Internet is the underlying backbone of the World Wide Web. Although this type of internetwork is popular and can be used in businesses, it is can also be the least secure type of network, especially is an organization doesn’t have the right anti-virus software, firewalls, and other necessary precautions.
The above is a simple overview of the most common types of computer networks. There are many other types of networks that could be beneficial to a variety of different organizations. Whether you need to connect computers in a single state or need California computer networking to extend all the way to New York, there are networks designed to meet your specific needs. By knowing about the different types of computer networks, you can better know which one is right for you and your business to help enhance communication and improve efficiency and productivity.
