Wireless Internet Terminology, like many things in life, especially those that have anything to do with computers is filled with terminology. But like most things, once you learn a few of the basic terms, understanding will come quickly. So don’t be confused get informed and to help clarify, I’ve put together a basic wireless “internet-to-english” guide to help you along.

IEEE – The Institute of Electrical and Electronics Engineers
The IEEE is in charge of the wireless networking standard, as well as many other computer-related standards – including the Ethernet standard. They ensure that computer equipment made by different manufacturers can work together.

PCMCIA – Personal Computer Memory Card International Association
Simply another standard for how to plug credit card size devices into a laptop computer to boost it’s capabilities. It’s been suggested by some that it should stand for “People Can’t Memorize Computer Industry Acronyms”. PCMCIA is a great way of adding wireless networking to your laptop as easily as inserting a disk.

PCI – Peripheral Component Interconnect
Used to install devices like graphics cards and network devices inside your computer. You would be using a PCI, if you wanted to install a wireless card inside your computer.

802.11
Set by the IEEE, it’s the current wireless networking standard. It helps ensure that wireless devices can communicate with one another or in other words – they are interoperable.

Interoperable
Simply means that two different pieces of equipment have the ability to speak to each other or another way to put it – they are compatible. They can use them together because they were designed using the same standards. Because of the IEEE and the principle of interoperability, all wireless equipment you purchase should be compatible.

Driver
Not a piece of golf equipment but computer software that informs a computer how to talk to devices that plug into it. Most wireless networking drivers come on a CD-ROM. You then download the drivers from the CD onto your computer.

Ethernet
Currently, the most common way of connecting to a LAN or Local Area Network. Most wires connected to your computer today are ethernet and if you have a cable internet connection an ethernet wire is in all likely-hood, what is being used to connect to your modem.

USB – Universal Serial Bus
A port used for connecting all sorts of devices to a computer, including keyboards, a mouse, printers, external hard-drives and basically anything else you can think of. If you don’t have a laptop or want to open up your computer you can get a USB wireless device.

WEP – Wired Equivalent Privacy
No longer used because in 2001 it was found to have security issues. As a result, it is now the old standard for encrypting wireless networks.

WPA – WiFi Protected Access
The new standard for encrypting wireless networks. An upgrade of WEP to fix security issues. To avoid becoming vulnerable, a WPA encrypted network changes encryption methods often. In addition, if an attack is detected, it has the ability to shut itself down for thirty seconds.

PAN – Personal Area Network
A network of devices connected together in one small area. A simple example of a PAN would be your computer, USB keyboard and mouse. Using a technology called Bluetooth, a PAN can be wireless.

LAN – Local Area Network
Briefly mentioned above, LAN is a computer network that… generally speaking is confined to one building, such as a home or office. A wireless LAN is also known as a WLAN.

MAN – Metropolitan Area Network
A network that covers a larger area, like a city or town. They are expensive but a wireless MAN has the capacity to spread Internet access across a wide area. Many college universities set-up a MAN to connect the entire campus.

WAN – Wide Area Network
A network that covers or connects to more than one physical site. A simple example would be a business that has locations in different cities, states or countries and they need them each location connected on the same network. The Internet itself is a WAN… the biggest WAN in the world.

Mbps – Megabits Per Second
Not to be confused with MBps, megabytes per second. Mbps is measurement of connection speed. There are eight megabits in a megabyte.

GHz – Gigahertz
One gigahertz is one billion cycles per second… it’s a measurement of frequency. If the term sounds familiar it’s probably because it’s also used to measure the processing speed of the CPU on your computer, which is also measured in gigahertz.

Linux
A popular and growing alternative operating system to Windows. Linux is a less bulky, more efficient operating system in many ways than Windows and not to mention – it’s free. Many servers run Linux for this reason. Computers running Linux can run many programs and connect to the Internet without needing Windows. Many wireless devices run Linux or are compatible with it.

Using internet fax service is an easy way to send and receive fax messages over the internet. Online fax services provide great advantages to its subscribers at affordable rates. By subscribing to internet fax services a customer can send and receive fax messages from anywhere at any time – what one need is a computer, an internet connection and an email ID.

Nowadays there are several companies offering web faxing services. Most of these companies provide a paid service and a free service. The difference between these two is that if a customer needs to utilize all the features of an online fax service he/she need to subscribe for a paid fax messaging service. Free services are offered with various limitations such as only receiving faxes or sending a limited number of faxes.

Using internet fax services is quite easy, the technology is similar to email services to a certain extend. To start using web fax services, first you need to subscribe with an internet fax service provider. The service provide assigns you a unique internet fax number. Same as email ID, this is the address to which other users can send in their fax messages. The subscriber also has to create an email id in the service provider domain, in order to send and receive faxes. This is where the users are supposed to type their messages and it is where the incoming fax messages will be delivered by the service provider. Once the user sent the fax message, the message will be dispatched to the service provider’s server, where it is converted into a suitable file format before eventually forwarding it to the recipient’s mail box or fax machine, whichever is applicable.

The advantages of using web faxing are that the users can send and receive as many faxes simultaneously or send all faxes instantly. Another major advantage is that, the there is no complexity of a conventional fax machine and those never-ending paper jams. The technology is quick and even cheaper than traditional fax messaging. So why spending time and energy with the traditional fax machine – subscribe for an online fax service now!

Apple on Monday is expected to unveil a next-generation iPhone and possibly provide a glimpse at long-absent chief executive Steve Jobs as it kicks off a software developers conference in San Francisco.

The northern California maker of iPods, iPhones, and Macintosh computers has remained tight-lipped as usual about what announcements it has in store, but speculation and rumour are rampant.

Apple’s keynote on Monday is to be tailored to an audience of software developers interested in crafting programs to work with the iPhone or Macintosh operating systems.

Talk that Apple might delay the release of Snow Leopard has heightened speculation that Jobs might make a keynote appearance to divert attention from the setback.

We all have many times heard about DVI, but what does it really means and what it does? What is the main function of this tiny white port on a video card? How it can benefit you and your personal computer? Do you know which DVI is suitable to meet your requirements?

Digital Video Interface is created by Digital Display Working Group to solve the problem of accommodation analog and digital interfaces just by using single connector. It was developed because of insufficiency of standardization in digital interfacing.

Three types of standards can be seen in DVI cables. It is very important to know how each type looks like before buying to upgrade your DVI. So it is very important to know how DVI cable works and which one will be most beneficial for you.

However, DVI cables are still in the phase of development. Hence there is no specific standard for the DVI cable. In ideal circumstances, DVI home theater cable is capable to create ‘ digital to digital’ connection between the data or video sources and home theater projectors.

The standard rule for DVI cables is that it should have maximum length of 5 m for trouble free operation. It is very typical to decide a DVI cable first time.

There are two types of DVI connector and each has its own characteristics. The flat pin denotes whether the cable is analog or digital. A flat pin with four surrounding pins denotes either DVI-A or DVI-1. A single flat pin denotes DVI-D. The pin sets depends upon whether the cable is single link or dual link or analog.

To choose a perfect Digital video interface cable you should remember these tips:

1.Check both female DVI plugs to make sure what type of signals they compatible with.
2.One or both connections should be DVI-D if you are choosing a DVI-D cable.
3.One or both connections should be DVI-A if you are choosing a DVI-a cable.
4.If one of the connections is DVI and other is VGA, and if the DVI is analog compatible, then you must buy a DVI/VGA adaptor or a DVI to VGA cable.
5.when both connections are DVI-1, you are advised to use any of DVI cable, but better if you use DVI-1 cable.
6. If one connection is digital and the other is analog then there is no possibility of connection between them.
