Wireless Networking Protocols tips
A protocol is a set of rules or agreed upon guidelines for communication. When communicating it is important to agree on how to do so. If one party speaks French and one German the communications will most likely fail. If they both agree on a single language communications will work.
On the Internet the set of communications protocols used is called TCP/IP. TCP/IP is actually a collection of various protocols that each have their own special funtion or purpose. These protocols have been established by international standards bodies and are used in almost all platforms and around the globe to ensure that all devices on the Internet can communicate successfully.
There are a variety of protocols currently in use for wireless networking. Arguably, the most prevalent is 802.11b. Equipment using 802.11b is comparitively inexpensive. The 802.11b wireless communication standard operates in the unregulated 2.4 Ghz frequency range. Unfortunately, so do many other devices such as cordless phones and baby monitors which can interfere with your wireless network traffic. The maximum speed for 802.11b communications is 11 mbps.
The newer 802.11g standard improves on 802.11b. It still uses the same crowded 2.4 Ghz shared by other common household wireless devices, but 802.11g is capable of transmission speeds up to 54 mbps. Equipment designed for 802.11g will still communicate with 802.11b equipment, however mixing the two standards is not generally recommended.
The 802.11a standard is in a whole different frequency range. By broadcasting in the 5 Ghz range 802.11a devices run into a lot less competition and interference from household devices. 802.11a is also capable of transmission speeds up to 54 mbps like the 802.11g standard, however 802.11 hardware is significantly more expensive.
Another well-known wireless standard is Bluetooth. Bluetooth devices trasnmit at relatively low power and have a range of only 30 feet or so. Bluetooth networks also use the unregulated 2.4 Ghz frequency range and are limited to a maximum of eight connected devices. The maximum transmission speed only goes to 1 mbps.
There are many other standards being developed and introduced in this exploding wireless networking field. You should do your homework and weigh out the benefits of any new protocols with the cost of the equipment for those protocols and choose the standard that works best for you.

Making Free Calls on The iPad
If you are one of the users of Apple's iPad , then you want to make the most of the investments you have made on your new piece of technological jewelry. Using VoIP on your iPad can make you save a lot of money and save you from using your expensive GSM minutes to make calls. You can use the iPad to make free local and international calls just like you would using a simple computer with an Internet connection, because the iPad has something of both a computer and a phone.
When Apple launched the iPhone, VoIP wasn't most welcome on board, due to resistance from Apple's network partners fearing loss of benefits to VoIP. Also, the phone itself was not open to every VoIP possibility in terms of applications. With the iPad, things are different, and it seems that Apple has known better.
The Requirements of VoIP over the iPad
What you normally require to make and receive voice calls on a computer are an Internet connection, a VoIP application and service, a voice input device (microphone) and output device (earphones or speakers). The iPad fortunately provides all that (could it not?), minus the VoIP service. But the latter can very easily be found - you will even have difficulty to choose in the near future.
Internet Connection on the iPad
One of the main hurdles to the adoption of VoIP on Apple's portable machines lately, namely the popular iPhone, was the restriction on using AT&T's 3G network. And you know that 3G is in many places the only wireless wide-area network available.
On the iPad, 3G is clear and can be used with VoIP. The machine also supports Wi-Fi and GSM. This means that you can make VoIP calls within your local area wireless network and also while on the move. Most of iPad users already pay a monthly bill for a 3G data plan. Using VoIP over 3G is a way of making up for the cost.
VoIP Applications and Services for the iPad
You need a mobile VoIP service in order to make VoIP calls on the iPad. Most of these services provide an application that you can install on your computer or phone and use as a softphone to make and receive calls. In these early days of the iPad, only a handful of applications and services are supported on the iPad, but a lot of others are likely to crop up like mushrooms in the near future.
Apple's development potential for applications isn't as large as for Linux and Windows, but Apple has updated the iPad's SDK (software development kit) such that anyone can develop VoIP applications for it.
So far, iCall works for the iPad. Skype just got its green light and will be launching and iPad client soon.

Latest Computers
Do you know what is inside your computer? Maybe you peeked when the service technician was installing something for you. When you first open up the CPU and look inside, a computer is a very threatening machine. But once you know about the different parts that make up a complete computer it gets a lot easier. Today's computers consist of around eight main components; some of the advanced computers might have a few more components. What are these eight main components and what are they used for? We will start with beginner level details to get you started.
First is the Power Supply. The power supply is used to provide electricity to all of the components in your computer. It is usually a rectangular box and is usually positioned in one of the corners of the computer. To find it for sure, look to see where the power cable plugs into the back of the computer and you have found the power supply. Most power supplies today are calculated in wattage and come in 50 watt increments (500 watt, 550, 600, etc
Second is the Motherboard. All of the components are connected into the motherboard; it doesn't mean that it is the brain of the computer. Yes it holds the brain and helps it act together with all the other components of the machine.
The third and a very important component of a computer is the CPU (Central Processing Unit), Known as the brain of the computer and nothing is going to happen without it. All major calculation performed by a computer are carried out inside its CPU. It is also responsible for activating and controlling the operations of other units of the system. The faster the CPU can do these calculations and give the correct answers, the faster the computer runs for the user. CPUs are now measured in gigahertz (Ghz) and they are at present up to our 3.8GHz or faster
A fourth component is the RAM (Random Access Memory). RAM is used as momentary working storage for the computer. We have different types of RAM memory with different speed, but it should match with your motherboard so that it can work properly. The more RAM you have in your computer, the better your computer will work.
The fifth component is the Hard drive. This is where you can store everything. Our material on the hard drive includes the operating system (Windows XP, etc), games, and different types of software, etc. over the year the capacity of the hard drive is continuously improving and in the interval of few years its capacity have gone from around 20MB to over 500GB and more. So you can store a lot more information on your computer such as games, pictures, videos, applications, and more.
Sixth component is Cooling fans. Often most computers come with one cooling fan or it might have several. Its help to cool down the heat generated by others components, Such as power supply, the CPU, and some high-end video cards. The work of all of your cooling fans is to get this heat out of the case so that nothing overheats and breaks. While most of the noise you hear coming from a computer can be credited to the cooling fans, remember to be tolerant. The cooling fan is your friend!
Our Seventh and final component is the mixture of several different devices. These are the Cd-rom, DVD drives, floppy Drive and Backup devices such as external hard drive.
