  1. In the peer to peer computer network model we simply use the same Workgroup for all the computers and a unique name for each computer in a computer network.
  2. There is no master or controller or central server in this computer network and computers join hands to share files, printers and Internet access.
  3. It is practical for workgroups of a dozen or less computers making it common environments, where each PC acts as an independent workstation and maintaining its own security that stores data on its own disk but which can share it with all other PCs on the network.
  4. Software for peer-to-peer network is included with most modern desktop operating systems such as Windows and Mac OS.

There are different types of communications connection in existence between two endpoints., Home networks, and the Internet is the one of the most commonly used examples. Many type of devices are and several different methods are used connecting to these type of network architectures.

There are different advantages and disadvantages to this type of network architectures. Connecting computers to a these type of networks, we requires some networking framework to create the connections. The two different computer network connection types are getting discussed in this page are Point-to-Point Connection and multipoint connection. The main difference between them we can getting discussed with the help of below definition.

A computer network consists of two or more computers that are linked in order to share resources such as printers and CD-ROMs, exchange files, or allow electronic communications. The computers on a computer network may be linked through cables, telephone lines, radio waves, satellites, or infrared light beams.

Computer Networks fall into three classes regarding the size, distance and the structure namely: LAN (Local Area Network), MAN (Metropolitan Area Network), WAN (Wide Area Network). Before we discussing about type of network we can discuss about what is a network.

What is Network?

In the today world, Two devices are in network if a process in one device is able to exchange information with a process in another device. Networks are known as a medium of connections between nodes (set of devices) or computers. A network is consist of group of computer systems, servers, networking devices are linked together to share resources, including a printer or a file server. The connections is established by using either cable media or wireless media.

Internetworking started as a way to connect disparate types of computer networking technology. Computer network term is used to describe two or more computers that are linked to each other. When two or more computer LANs or WANs or computer network segments are connected using devices such as a router and configure by logical addressing scheme with a protocol such as IP, then it is called as computer internetworking.

• A Computer networking model where one or more powerful computers (servers) provide the different computer network services and all other user'of computer  network (clients) access those services to perform user's tasks is known as client/server computer networking model.
• In such networks, there exists a central controller called server. A server is a specialized computer that controls the network resources and provides services to other computers in the network.

There are many type of Serves in the Computer Networking World. Server is a machine, that can be design for interconnecting the machines with each other.Many type of the functions are performed by the servers to facilitate different uses. Let us discussed first, what is a server before getting discuss about type of servers.

Types of Computer Networks can be classified on various properties. The Computer networks can also be classified on the basis of Computer network technology used by them. There are two types of Computer networks in this category.

During 20th century the most important technology has been the information gathering, its processing and distribution. The computers and communications have been merged together and their merger has had a profound effect on the manner in which computer systems are organized.

A computer network can be classified into different categories. Different criteria are used to classify computer networks. Following are the criteria widely used.

The access point (abbreviated AP or WAP (for wireless access point)), is a networking hardware device, such as a wireless router, that transmits and receives data (sometimes referred to as a transceiver) and also can serve as the bridge between the WAP device and a wired LAN (Local Area Network), which facilitates connectivity between nearby wireless clients. A WAP (also known as a hotspot) acts as a central transmitter and receiver of wireless radio signals.

Data Communication or Network Communication: It is the process of transporting data or information from one device to another.The channel or physical connection (path) through which the information is carried from sender(Source or origin) to the receiver(destination) is established using either cable (Physical media) or wireless media. The physical cable like twisted pair wire, coaxial cable, fiber-optic cable or wireless media like laser, radio waves, and microwaves.

Internet access has become a standard feature on most of our mobile devices. But there’s more than one way to connect to the Web with those devices these days. In this article, we’ll help you determine what you need in order to get started with each of these technologies and explain a bit about why you would want to choose one over the other or perhaps go with both.

WiMAX (Worldwide Interoperability for Microwave Access) is the result of an initiative launched in 2001 by the WiMAX Alliance. Its aim was to promote the IEEE 802.16 standard by proposing to verify compliance and equipment interoperability. As we shall see, many options have been proposed to achieve communication.

The quality of service is essential to ensure the transfer of real time data such as voice or video. Such services require isochronous transfers, that is to say data transfers that enable to vary the time between the different frames of the same transmission. In the case of a video application, for example, over this period, the greater the quality deteriorates, whether audible or visual. To minimize this delay, priority mechanisms were introduced by an extension to the 802.11 standard, called 802.11e.

With pre-IEEE 802.11n products, the maximum speed reached in late 2007 is 108 Mbit / s, that is to say double the IEEE 802.11a and 802.11g standards. This flow rate is achieved by increasing the density of transmitted bits. Technological advances are such in the field of radio transmission it is now possible to improve greatly this flow. 802.11n networks offer a potential gross rate of 540 Mbit / s. In fact, the actual flow rate is much lower and is of the order of 100 Mbit/s in the best case.

The IEEE 802.15 group was set up in March 1999 to reflect on wireless networks with a range of ten meters, or WPAN (Wireless Personal Area Network), with the aim of making connections between different portable one user or multiple users. This type of network can connect a laptop, cell phone, PDA or any other device of this type. Three service groups were defined, A, B and C.

Ethernet networks at 10 Mbit/s were the first to be introduced in the market. They still represent a significant proportion, although standards to 100 Mbit/s tend to supplant them. This section reviews the various products of the Ethernet shared working at a speed of 10 Mbit/s.
