Know Your Mobile Device

Since mobile devices came into being, there have been many variations in their style and design. Companies are continuously coming up with different techniques to vary and add more appeal to their products. What started as basic mobile devices have been further subdivided into various new categories. This article deals with three devices which have been further subdivided.

The first device is the PDA phone. A personal digital assistant is a smart device that helps individuals to plan and organize their work. There are various types of these devices including:
Traditional devices
These can be termed as descendants of the original devices. They use the original operating systems for the devices including Windows Mobile and Palm OS.
Palm devices
Palm mobile devices are made by the Palm Company which was formed in 2003. Their product line includes the Tungsten and the Zire products.
Pocket PCS
These are devices that operate using the Windows Mobile OS. They pack a lot of features just like conventional computers, including office and synchronization.
Smart phones
Smart phones are traditional PDAs with cell phone capability. The devices use cellular networks to browse the internet and use their telephone services. They also make use of different varieties of operating systems depending on the manufacturer.

Many people use their PDAs without knowing the type of device that they own. The above will help users determine the type that they are using.

Touch phones are types of mobile devices that use touch screen technology. These phones are classified according to the type of screen that they use. The main types of screens are:
The resistive screen. This screen uses pressure to highlight an object on the screen. It has two layers of screen. Plastic dots are placed between the two screens to prevent them touching. When a person presses anywhere on the screen, the two screens are connected. This generates electricity which activates the highlighted object. This screen is however affected by scratches.
The capacitative screen is another screen that can be used. This uses just one screen but with an electro conductive material. When the screen is touched by an object, it creates a flow of electricity and a contact point is established. The good thing about this screen is that it has a very long life, but is unfortunately very expensive.
An infrared screen can also be used on a phone. The infrared screen is divided into optical and heat infrared. The heat sensitive type is the most commonly used. It senses when a warm object touches it. The shortfall of this is that it can only be touched by warm objects such as a finger. The optical screen uses a grid of optical infrared rays around a screen. When a point is pressed the grid is broken and a contact point is established. This screen is however impeded by dust, scratches and strong light. It is also the most expensive.

The cell phone is the other broad classification of mobile devices. The cell phone basically is a phone that uses wireless technology to facilitate communication and is powered by a cell. Cell phones are classified according to their basic design. The first mobile phone type is the clam shell type which designed just like this shell. To open the phone, one flips the cover to reveal the keypad and the screen.

Another design for the cell phone is the slide phone. The keypad is revealed by sliding the phone either sideways or vertically. The most basic design of the cell phone is the single piece cell phone. It is a just a bar kind of phone with the screen and the keypad in the same area.

The above broad classifications of various mobile devices will enable a user to know the type of mobile device they are using.
