The Internet – The Largest Network in the World

March 3rd, 2010



Computer engineers have been finding ways to connect computers and their devices together in different ways. Computer networking has come hand in hand with other bodies of knowledge such as telecommunications, information technology, and computer engineering. So many things have been made possible through computer networking. It has helped people live easier lives in many ways through personal area network, local area network, metropolitan area network, and wide area network.

One great example of a wide area network is the champion of all networks, the Internet. It is the biggest network in the world, and billions of data (maybe even trillions) is being transferred everyday. So much information is exchanged and it has practically changed the way we live our lives.

Education online

The usual way to get your education is to enroll in a school, and go to your classes on a fixed schedule. Nowadays, we can actually get a college and master’s degree through the Internet. A lot of reputable universities now offer their courses online because they understand how hard it is for some students to juggle a job and their schooling. Depending on the program, you can have your own schedule, and usually you’d just have to submit work on or before a particular deadline. At times, you’d have real time chatting with you professor and “classmates”, sometimes even with a webcam. What’s great about this is that you no longer have to go through the hassle of commuting. The good news is that companies have been accepting a lot of applicants with this sort of education but there are still some that are overly traditional.

Video games galore

What started out as simple 2 dimension games is now a multi-billion dollar industry, and has spawned a new way of social interaction. Because of the Internet, gamers are now able to interact with people from across the globe, and play the same game at the same time. This is great because video games were once viewed as an anti-social activity. This is no longer true and now gamers not only get to play the game together, but are able to chat and make new friends as well. Internet gaming has also created a new gaming genre called “massively multiplayer online role-playing games” or MMORPGs. This is a supercharged type of RPG where thousands of players get to play together in a particular game at the same time.

Social Networking

A lot of websites nowadays allow people to interact and socialize with each other with their different tools and services. Some of them are focused on dating, where users can create their own profile and indicate their particular tastes. Other websites are dedicated to people uploading pictures and sharing them with other users as well. This has been a great way of connecting with long lost friends, and making new ones as well.

It’s great that computer networking has helped in bringing us the Internet. With it, life has become more convenient, and we can learn so many new things everyday just by connecting to it. With the Internet, there are certainly more new things to come.

Computer Network – Comprehensive View – Part 2

November 13th, 2009



Wireless networks located in multiple categories, depending on the size of the physical area that can be covered by network.

The following types of wireless network meet the needs of multiple users:

* Wireless personal – Area network (PAN).

* Wireless Local Area network (LAN).

* Wireless Metropolitan-Area network (MAN).

* Wireless Wide – Area network (MAN).

This is using the expansion all major cables for wired networks (such as LAN or WAN) used for years before it enters the wireless network.

Each type of wireless network has the advantages of complementary meet multiple requirements. The following paragraphs explore each type of wireless networks in a concise manner.

Wireless networks (PANS):

The area of wireless networks is a relatively short (up to 50 feet) and most of their effectiveness to meet the needs of a small room or in the cargo area. PANS networks is the performance of the average of data rate of up to (2MBPS). Imperatives followed these advantages for the replacement of cables in many cases.

PAN wireless network includes a person synchronize personal PDA with his laptop computer or personal computer. In a similar, PAN wireless network can provide radio communication to the printer. The advantage of the abolition of knots in the wire when using this type of computer is very useful, where the initial installation of the equipment is easy.

Wireless networks (LANS):

Networks wireless LANs provide high performance within and around office buildings and labs, and homes often have the users in these areas laptop computers, personal computers, PDA screens and processors to support large applications. LANS meet the requirements of communication for these types of computers effectively.

For example, in the work it can be installed the wireless LAN network to provide mobile access to the common applications of laptops. This type of system, the user can, while far from his office, take advantage of network services from the conference rooms and other rooms. That allows staff to be more effective while working away from their offices and more cooperative with each other.

Wireless networks LANS provide the performance levels enable applications to operate smoothly. For example, the wireless network LAN users can easily see e-mail attachments or a large scale video server of the invisible with data rate up to (54 MBPS). Wireless LAN network can meet only networks with the limits of web applications a house or office.

Wireless networks (MAN’S):

MAN’S wireless network includes areas with the size of cities.

Wireless Service Providers (WISPs) Provide wireless networks in cities and remote areas in order to provide homes and firms for wireless communications. Wireless networkings MAN provides the positive benefits and are appropriate when it is impractical to install a traditional wired communications such as (DSL and cable modem). Wireless networks WANS are effective when the right path for the cable systems have made it not possible or too expensive.

Wireless networks (WAN’S):

MAN networks known as mobile wireless applications cover a large area, such as state or continent. Because of the economic side, the operator is able to do remote deployment of the operational infrastructure of the wireless network MAN in order to provide relatively inexpensive long-distance communication for a lot of consumers. It is possible to distribute the costs of such a deployment across multiple users. It provides low fees -subscription.

Virtual Private Network and Network Connections

November 6th, 2009



Network In information technology, a network is a series of points or nodes interconnected by communication paths. Networks can interconnect with other networks and contain subnetworks.

Local Area Network (LAN) A local area network (LAN) is a group of computers and associated devices that share a common communications line or wireless link. Typically, connected devices share the resources of a single processor or server within a small geographic area (for example, within an office building). Usually, the server has applications and data storage that are shared in common by multiple computer users. A local area network may serve as few as two or three users (for example, in a home network) or as many as thousands of users (for example, in an FDDI network). See also: WAN and MAN

Wide Area Network (WAN) A wide area network (WAN) is a geographically dispersed telecommunications network. The term distinguishes a broader telecommunication structure from a local area network (LAN). A wide area network may be privately owned or rented, but the term usually connotes the inclusion of public (shared user) networks. An intermediate form of network in terms of geography is a metropolitan area network (MAN).

Metropolitan Area Network (MAN) A metropolitan area network (MAN) is a network that interconnects users with computer resources in a geographic area or region larger than that covered by even a large local area network (LAN) but smaller than the area covered by a wide area network (WAN). The term is applied to the interconnection of networks in a city into a single larger network (which may then also offer efficient connection to a wide area network). It is also used to mean the interconnection of several local area networks by bridging them with backbone lines. The latter usage is also sometimes referred to as a campus network.

Network Backbone A backbone is a larger transmission line that carries data gathered from smaller lines that interconnect with it.

Nodes In a network, a node is a connection point, either a redistribution point or an end point for data transmissions. In general, a node has programmed or engineered capability to recognize and process or forward transmissions to other nodes.
