what is a cpu? CPU stands for Central Processing Unit. There can be several processors in a computer, but one of them is the central one – the CPU.The reason the CPU is called a processor is because it can work with data. And it has two important jobs: 1. It can do calculations. 2. It can move data. The CPU is very fast at doing both jobs. The faster the CPU can do calculations and move data, the faster we say the PC is. There are three ways to improve a PC’s performance: 1. Higher clock frequencies 2. Greater bus width. 3. Optimising the core of the processor and other components so that the maximum amount of work is done for each clock tick.

PDA's ,portable computers came out in the mid to late 1980's. they had small keyboard attached with them a small display n basic features like alaram , calendar, calculator etc. They supported games and spreadsheets The Psion Organiser II, released in 1986, was very popular In 1993, Apple introduced the Newton MessagePad.It had electronic notepad, to-do list, calendar, telephone log and address file applications. The original PalmPilot was launched by Palm Computing in March of 1996. The PalmPilot ran for weeks on AAA batteries, was easy to use, and could store thousands of contacts, appointments and notes. A typical PDA: the Hewlett Packard iPAQ Pocket PC.

So what PDA really is? PDA is Personal Digital Assistant which provides the functionality of a cellular phone , web browser personal organiser n more. Input is usually using pen ie they are incorporated with handwriting recognition . It also has voice recognition functionality. PDAs are also called palmtops, hand-held computers and pocket computers.

intel core 2 duo processors were launched on 27th July 2006 at Fragapalooza n code named CONROE. they are built on 65nm process n manufactured with 4MB L2 Cache some of the processors available are E6300(1.86Ghz) n E6400(2.13Ghz) with both having 1066 MT/s FSB they have enormous value for overclocking capacities according to a study a 1.86Ghz processor has been overclocked to 3.0Ghz with motherboard supporting high FSB's

so what is core 2 duo? its an intel technology which is intel core 2 duo which based on intel core microarchitecture what really happens is 1.increase in delivering of instructions per clock cycle thereby decreasing exectuion time n increaing energy efficiency 2.more power efficient performance and more battery life for laptops 3.optimise the use of available data bandwidth 4.more efficient cache subsystem for these processors read on for more info
