Types of Computer Networks - Networking

Before the kind of tissue in the computer information systems must better understand what is the definition of a computer network, which is a system that connects multiple computers to each other through a variety of media liaison. That way, each computer can communicate with each other, both for data sharing, security and sharing together computer equipment such as printers, scanners , other peripheral and many of others. The type or specification between computers that are used not to be the same or similar to be interconnected. Most importantly each computer has a connection device such as a LAN card, Bluetooth, Wireless Card, or other and use the rules of the protocol or the same communication rules, or also called TCP / IP (Transmission Control Protocol / Internet Protocol).

Computer Network Based Function
Various computer network when viewed from the function can be divided into two :

1. Network Peer-to-peer

Type this network, each computer is connected directly to the other using a single line. Its use without additional communication devices or servers as well. This network can only connect two computers. Type of first popularized the file sharing applications such as KaZaA or Napster. The idea of ​​this concept was born around the end of the 1980s when computers became a mandatory inventory every small company or large companies. The advantages of peer-to-peer systems is the search and removal of data quickly. The process is faster than to move a data into flash and then save it to another computer.

2. Client Server Network

In this network it takes one unit of the computer that will be used as a personal communication tool or a server. The point is to connect between one computer to another computer. Thus, the computer can be connected to more than one unit with more line. Excess on this network that all the data can be stored in a single place (server). Thus, placement and processing of the data to be more organized. But this could be a weakness teryata also because if the server is experiencing interference with the network, all the computers can not access the data. That's all kinds of computer networks based on function that turned out to have different functions from each other.

Computer Network Topology

In Topology various computer networks can be divided into four types :
1. Bus Topology

Each computer connected to the network path of the primary data path or back bone by using a cable. More generally these networks are connected in parallel. These networks are often used on networks with fiber optic base. Network installation is very simple, optimal, inexpensive, and quite optimal. Maximum that computer in the network is between 5 to 7 units. Difficulties often happens that the data collisions due to the mechanism of the bus topology is very simple. The drawback is that if interference occurs along the cable server, all networks are disrupted.

2. Ring Topology

In this network using the principle of the circle, in the sense that technically each computer to connect the two computers together. So it is with the other until no end or a computer that is disconnected. More generally these networks are connected in series. Weakness of this type of network that is if there is one computer that is having problems with the system network, the entire network of others computers be disrupted. But with the FFDI network can be used to anticipate these shortages. With data transfer clockwise or anti-clockwise simultaneously. The advantages of this network is to have a maximum speed compared to other types of networks. The network is able to use features that require real time services such as video and audio. The weakness of these networks is the difficulty in detecting damage. Especially if there is damage, it could be the cause of the collision or the terms of the merger of the two groups of data.

3. Mesh Topology

Similarly, the type of peer to peer networks, but using more than two computers. That's why network system model is not efficient because too many computers in it. While each computer must be connected directly. Finally making the system complex in organized network systems. This is caused by each of the two computers that need to have a separate line. The advantages of this network place in the assurance of data that can be directly sent to the destination computer without having to pass through other computers so Premises, yag data transfer speed will be used to be more optimal. In the event of interference on one computer, the other connections will not be disrupted.

4. Star Topology

This type of network can be a solution of this type of mesh networking. The reason is because each computer using only one line. One line is what will be connected to a communication tool. The relationship is what we are familiar with the hub or switch. With this tool, the arrangement of the network system will be more efficient. If one computer to crash, does not interfere with other computer network systems. The advantages of this network for the data traffic that is the stability when the network is busy. That's all kinds of networks if we see based on the topology. Each network topologies of various networks has its own advantages and disadvantages of each. Its use can be tailored to your needs.

Computer Networks by Area

Whereas if you look at a variety of networks based on the area, the network can be divided into three :
1. Local Area Network (LAN)

This type of network is just connecting computers together locally to exchange data or information. These networks are often used on small networks in some rooms or institutions connected with the main network hub or gateway called. Most LAN-based technology that uses the IEEE 802.3 Ethernet switch device. Wi-Fi or 802.11b technology is also often used to create a LAN network, or often called a hotspot. LAN Network has a data transfer speed of the highest among other types.

2. Metropolitan Area Network (MAN)

Network MAN is the development of methods of larger LAN network by using more than one gateway. Further connected through one main server. This type of network is often applied to the network in the campus area, urban or office because network coverage is very broad. Could include between 10 to 50 KM. This type of network is often also referred to as an intranet. Some of the technology used in a WAN is the Asynchronous Transfer Mode (ATM), SMDS, and FDDI.

3. Netwok Wide Area (WAN)

This network has a very wide scope for using more than one main server, which then each server will be connected via its own network in order to connect. This network covers an area of ​​inter-state or a world that is now known as the Internet. In the day-to-day application, to connect the WAN to a LAN network will be needed tool to manage its gateway called routers and public communications channels.

Various kinds of network characteristics and ways of working are different from each other, including differences in the extent of coverage. Therefore the choice is in your hands, which you will use from the various networks.

Know the Types of Computer Networks

The types of computer networks would have you know, especially if you are wrestling in the world are struggling on a network problem. The reason is, the types of computer networks is usually one of the lessons if you enter a study at the Tissue Engineering. Indeed in the world of computers, types of computer networks is one of the knowledge base, where you will be introduced to a system of interrelated and networked in a space that collected in an object named a computer. We know if this is a performance in which computer networks can facilitate human work and because it provides maximum efficiency in a mechanical activity.

Types of Computer Networks - Five Types of Computer Networks

Indeed, the world's computer networks, we know some types of computer networks. Surely this has been familiar for those who are concerned to learn what and how other types of computer networks during college. So here you will get some interesting facts about what is actually available on the types of computer networks.

Discussion on the types of computer networks actually be something easy to remember. However, how do I then put it into practice yourself into a form of computer network in a circle, is a difficult thing. Will be discussed here are only five types of computer networks that are usually used. What are the five types of computer networks ?

1. LAN (Local Area Network)

First, in the types of computer networks we are familiar with terms that really are not strangers in the world of computers. For the first type is called here is a Local Area Network, or commonly abbreviated to LAN. What exactly is this LAN ? Local Area Network or LAN is a network type that is usually owned by private, for example in an office or campus building with a range that can reach several kilometers. In addition, the LAN itself is usually also used to connect computers in the company of a personal nature, such as the factory with the use of resource with printer, scanner, and others. And is also commonly used to exchange information with each other.

Associated with the LAN as one of the types of computer networks, then the LAN actually be distinguished according to three characteristics that exist in itself, the size, transmission technology, as well as topology. In the meantime, if viewed from its size alone, it is true LAN has a limited size. Which means that in conditions of limited transmission time could have known well in advance.

Well, if you then have managed to find out what are its the limitations, and then you could be wearing a certain type of design that is better. In other words, the condition is aimed to get the ease of maintence of a network. Other information, this type of LAN networks often use technology that is single-cable transmission. On the type of LAN that is traditional, he usually operates at a speed range starting from 10 up to 100 Mbps (mega bits / second). With lower status or simply delay the recounts of tens of micro second course.

In addition, the LAN also has a relatively small error factor because its not complicated. However, in the types of LAN computer networks that are often found in the modern era such as this, and the operation speed can be very high. In fact, the hundreds of megabits per second.

2. MAN (Metropolitan Area Network)

Second, is a computer network called the MAN or Metropolitan Area Network. These types of computer networks is a true MAN LAN version, but has a larger size and are technically often use technology that is not much different from the LAN. In fact, the same as LAN.

Because it is a wider scale, then the computer network of this type MAN, MAN is able to reach the corporate offices are in very close distance. But, it can be used for personal purposes. For example, the region also are private or public.

In addition, MAN capable of supporting data and also can accommodate the sound. Even if one is required, MAN computer networks are able to make contact with the cable television network, as is already widely practiced by many people.

While from its own kind, MAN has only one or two wires. MAN and the drawback is it has no element named switching. Where the benefits from the existence of this switching is to regulate the output packets over multiple wires on the network. In other words, the existence of this switching element can make a design on the computer network becomes much simpler and easier.

3. WAN (Wide Area Network)

The third type is a WAN or Wide Area Network. On the WAN network is distant enough to have differences with the network already in the initial dibahasa. Because the Wide Area Network or WAN is unable to reach or geographic regions that are more extensive. In fact, the use of the WAN is also usually reach in a country or even continent. This is because the WAN is a network whose existence consists of a collection of machines in order to carry out the application programs that are needed and prepared.

In traditional usage, usually we call it the host name of the circuitry. However, in recent literature have described the use of the term End System. As for how it works, this host alone or connected to use subnet communication is then commonly known or referred to the subnet only.

So what is its own subnet assignment in this WAN network ? The answer is, to carry messages from one host to another host. Which, when equated, then the exact same with the use of the telephone system. In which the speaker will talk delivered to the far penedengar location.

Obviously with the separation of pure communication aspects of a network or subnet, of those aspects of the application or that we are familiar with the term host, it will make a draft on the network to be complete. And other advantages are that it can provide something much simpler.

4. Wireless Network

The fourth type of network is the network without wires. The types of mobile computer networks, such as computers, laptops, netbooks, personal digital assistant (PDA), etc. are the obstruction phenomenon that goes in the computer industry with a fairly rapid growth. Mobility that allows a person to be faster in doing something because it can be done anywhere. This makes the wireless network of choice.

In other words, wireless networks allow people to perform activities, such as the phone call, fax, e-mail read, read file for long or short distance, even able to login on a machine even in remote public or personal areas. Anytime, everywhere, and anywhere.

5. Internet

In this section other types of computer networks, the network of the latter is the internet. As we all know, is interconnected with the network hardware and software is what makes us connect with people.
