Internet History: Beyond ARPANET
The Internet's beginnings took place in a United States Department of Defense program for a strategic computer network. It was designed to carry sensitive and critical data over a computer network that was supposed to be able to remain intact in the event of nuclear attack. The project was called ARPANET, for "Advanced Research Projects Agency Network. The ARPANET was based on a packet-switching network. Any given unit of data could be divided into packets, and these packets could be sent computer to computer, to be reassembled by the receiver. Along the way, these packets of data were routed through various computers along the network, requiring that each computer be able to communicate with all the others. The network was designed to provide simultaneous links among all the computers on the network.Read more…Using a Bluetooth Headset with your PC

When you buy a wireless router it is not secure and its default configuration will allow unwanted users that are in the vicinity of your router to connect to the internet and "steal" your wireless router internet connection. They could also gain access to your PC and steal files and folders of data. Manufacturers leave the configuration "open" so that the user can easily set up the router and get it up and running quickly. However, there is a risk if the router is not secure.

As broadband Internet becomes more mainstream, one of the most common questions we get is: which is better, cable or dsl? The answer to that question is not so definite. Many factors come into play when deciding which high-speed connection to choose. Regardless of which you choose (DSL, Cable, or even Satellite) it's going to be a ton better (and faster) than that ancient dialup modem you've been using. Not to mention, your Internet experience will be much more enjoyable. Read more…What Will It Be Like When You Are Online All the Time?
A man walks down the street, waving his arms and talking to himself. No problem, he's dictating an email. A woman sits on a park bench, stabbing at a pocket computer with a plastic stylus. Is she selling shares or checking the contents of her fridge? Read more…Satellite Internet Service is The Answer for Individuals in Rural Communities
Living in a remote part of the world can be both tough and inconvenient. Not only must a resident of such secluded areas travel miles for simple things like groceries and entertainment but are almost always limited in the types of internet connections available to them.Read more…Internet telephony
Presently, Internet telephony is preferred all over the world, due to the fact that it is much cheaper compared to traditional phone services. Many people have friends and family living in foreign lands, and they often have to use long distance phone service for communication purpose. But the long distance phone calls are quite expensive for low budget users. Read more…Some Tips For Buying home computers Wireless Routers
The advent of wireless routers has helped small offices and home computers interconnect and function fast. No more sharing of files with thumb drives or squabbles over who will access the internet fast. Read more…Photocopiers Become WiFi Enabled
WiFi technology can be found in almost every modern computer, which has given people the freedom to connect to the internet whenever it is needed and for offices to connect all their computers to a single network without needing any wires. This technology has now been introduced to photocopiers, printers and multifunctional devices, meaning they too can be connected wirelessly to any computer network.Read more…A word about Wifi or Wi-fi Technology
WiFi is the other name for wireless internet or wireless network, this name is mostly used by none technical users who just knows how to access internet wirelessly, they know pretty much nothing beyond that. WiFi is basically short form for wireless fidelity. However many advance users are not well aware of this terminology either, it is, more known with a name of Wifi. WiFi term is written in many ways which are, Wifi, WiFi, WIFI, Wi-Fi fiwi etcRead more…How to find a Used Juniper Hardware Vendor

Earlier we said that a muter takes a packet arriving on one of its attached communication links and forwards that packet on to another of its attached communication links. But how does the router determine the link onto which it should forward the packet? This is actually done in different ways by different types of computer networks we will describe one popular approach, namely. The approach employed by the Internet. In the Internet, each packet traversing the network contains the address of the packet's destination in its header.Read more…File Transfer Protocol: FTP
We have just learned that network processes communicate with each other by sending messages into sockets. But how are these messages structured? What are the meanings of the various fields in the messages.Read more…ISPs and Internet Backbones
We saw earlier that end systems (user PCs, PDA's, Web servers, mail servers, and so on) connect into the Internet via an access network. Recall that the access network may be a wired or wireless local area network (for example, in a company, school, or library), a residential cable modem or DSL network, or a residential ISP (for example. AOL or MSN) that is reached via dial-up modem. But connecting end users and content providers into access networks -is only a small piece of solving the puzzle of connecting the hundreds of millions of end-systems and hundred of thousands of networks that make up the Internet.

Before diving into software coding, you should have a broad architectural plan for your application. Keep in mind that an application's architecture is distinctly different from the network architecture.Read more…History of Computer Networking and the Internet
You should know enough now to impress your family and friends! However, if you really want to be a big hit at the next cocktail party, you should sprinkle your discourse with tidbits about the fascinating history of the Internet. Read more…Messages, Segments, Datagram's, and Frames
The physical path that data takes down a sending end system's protocol stack, up and down the protocol stacks of an intervening link-layer switch and router, and then up the protocol stack at the receiving end system. As we discuss later in this book, routers and link-layer switches are both packet switches.Read more…Wireless Access
Accompanying the current Internet revolution, the wireless revolution is also having a profound impact on the way people work and live. Today, more people in Europe have a mobile phone than a PC or a car. And the wireless trend is continuing with many analysts predicting that wireless (and often mobile) handheld devices -- such as mobile phones and PDAs-will overtake wired computers as the dominant Internet access devices throughout the world. Today, there are two common types of wireless Internet access.Read more…

Before diving into software coding, you should have a broad architectural plan for your application. Keep in mind that an application's architecture is distinctly different from the network architecture. From the application developer's perspective, the network architecture is fixed and provides a specific set of services to applications. The application architecture, on the other hand, is designed by the application developer and dictates how the application is structured over the various end systems - Networks Under Attack - By: Imran Rashid
The field of network security is about how the bad guys can attack computer networks and about how we, soon-to-be experts in computer networking, can defend networks against those attacks, or better yet, design new architectures that are immune to such attacks in the first place. - Wireless Access - By: Imran Rashid
