what is the full form of P-ISM in 5 pen pc technology?

Computer affects our life in a much bigger way than most of us could have thought. It has become a mandatory requirement in most professions to use computer software. The first computer invented was the ENIAC in 1943, which was the same size as a large room, consuming as much energy as several hundred modern PCs. Modern computers that rely on integrated circuits are small enough to fit on mobile devices. One of the most compact computers at the moment are the desktop computers with the most popular is the iPad, but even that is 9.1 inches and weighing 700grams. But imagine having a computer that will fit in your pencil box.
The P-ISM (Pen-style Personal Networking Gadget Pack) consists of a 5-pack of pens that have unique functions combined to create a virtual computing experience. This is just a prototype in the development phase of NEC Corporation. In 2003, Geneva hosted the ITU Telecommunication Word Exhibit, which featured a $ 30,000 conceptual prototype of a P-ISM designed by the Tokyo-based NEC Corporation.

The P-ISMs are connected to each other through short-range wireless technology. The first pen is a CPU, the second is a camera, one creates a virtual keyboard, another projects the visual output and the last is a communicator (a telephone). The whole set is connected to the Internet through the function of cell phone.P-ISM ("Pen-style Personal Networking Gadget Package"), which is nothing more than the new discovery, which is under development, by NEC Corporation. 5 Pen PC Technology is a package of gadgets that includes five functions: a pen-style cell phone with a handwritten data entry function, a virtual keyboard, a very small projector, a camera scanner and a personal identification key with function Transfer without cash.

5 Pen PC Technology are connected to each other through short-range wireless technology. The set is also connected to the Internet through the function of cell phone. This personal gadget in a minimalist pen style allows ultimate omnipresent computing.

In fact, no one expects much activity on 802.11n installations until mid-2008. "The deployment of 802.11n would mean a major upgrade for customers who already have full Wi-Fi coverage and would be a complex complement to those already in place. Which do not have. Bluetooth technology is widely used, since we can able to transfer data or make wireless connections 5. Pen PC Technology is very effective, because we can connect whenever we need it without the need for cables. Frequency band of 2.4 GHz ISM (although they use different access mechanisms).The blue tooth mechanism is used to exchange signal status information between two devices. 5 Pen technology techniques have been developed that do not require communication between the two devices (such as Blue tooth's adaptive frequency hop), the most efficient and complete solution for the most serious problems can be achieved by silicon vendors . They can implement information exchange capabilities within blue tooth designs. The circuit diagram for the 802.11B / G is given below. It is nothing but blue tooth type as well. Using this connectivity we can also connect it to the Internet and we can access it anywhere in the world.
