Lenovo IdeaCentre Q150 : SPECS, DETAILS, PRICE, REVIEW

Lenovo introduces its full HD PC the extremely compact and ultra-slim IdeaCentre Q150. The OS on it is Microsoft Windows 7. The get an optimum speed it is built with Intel Atom (single core processor) with hyperthreading technology (@ 1.6GHZ). From the graphics point of view Integrated NVIDIA ion dedicated graphics card is provided with a memory of 512 MB.

The storage capacity is 250GB. The networking features includes Wifi and 1 ethernet port. The system has a memory of 2GB(DDR2). One of the speciality is that it is provided with Sleek Wireless Keyboard with a unique shape. The dimensions are 6.7 inches (h) x 0.82 inches (w). Other key features include HDMI port, VGA, two USB 2.0 port (both at front and rear), JBL speakers, TV connectivity, plug and play design.

So the PC from its design point of view is good and perfect. Latest tech like wireless keyboard adds to it. The size is also some what small and adjustable and that is optimum for a user. Most stunning it consumes less energy than a 14-watt bulb. The only problem may be from the performance point, it can't be told as a problem. The performance is just only average with its design, power consumption, size being above average. Its price is $249 USD.

Working of touch screen-resistive system

Touch screen phones and computers are now available at cheaper price in our market. Lets see what is the technology behind it.Three systems are used to detect the touch of a person. I am going to explain one of these.
Its called the resistive system. It consist of a normal glass layer which is a good conductor and also a metallic layer. Between these two layers there are space.An electric current runs through these when the device is operated. The outer most layer is scratch-resistant and when a person touches it the previously mentioned two layers come into contact at the exact spot. The electric current variation at that spot is noted and the coordinates of the point are noted by the computer(or phone). Once this coordinate is known it is then converted into signals by drivers and a detected by an operating system(as the movement of mouse is detected).

Speed of light

Imagine computers working in light's speed, Super of the super computer.Yes a new gateway to human innovations has arrived- chips with speed of light.Scientists of Massachusetts Institute of Technology developed new infrared made from germanium.After 1950s there had been 15,000 different lasers but this is unique due to two main reasons

• It operates on room temperature
• It uses low power

"Using a germanium laser as a light source, you could communicate at very high data rates at very low power," said Jurgen Michel of the Massachusetts Institute of Technology, who developed the new germanium laser.In the creation of Germanium laser they used a six-inch, silvery gray disk of silicon and sprayed it with a thin film of germanium.These lasers will also be used in many electronic devices and these are the turning points in human innovations.

Beyond microchips

Microchips revolutionized the world. Its not possible to think about any electronic device with out a microchip in it. Microchip manufacturers are in a run to make the next generation fastest chip. In the near future this will hit a wall. These which are made of silicon will once reach its speed limits and miniaturization. They will search for a new material after that to produce computing speed.

This search for the next generation microprocessors has now came to an end. Scientists found that millions of super computers exist inside living organism. DNA (deoxyribonucleic acid-a material our gene is made of) is having high potential to perform calculations many times faster than the fastest computer by human. One day will come when DNA will be used as a microchips so as to fasten the computer. DNA computers can store data, billions of times more than any PC. Lets wait for the 'BIOCHIP' to be on market to fasten ourselves.

Future of internet- Brainnet

The next world of internet is not far.Scientists in Britain have developed a System that creates "BRAIN TO  BRAIN COMMUNICATIONS".
Actually this was put forward to help people, who had disability.It is a technique that allows computer to analyse brain signals, that enabled them to sent messages formed by a person's brain signals though an internet connection to another person's brain miles away.
Working

Two people are connected to electrodes and it detects activity of certain parts of brain.For eg the first person generates ones and zeros, where they imagined moving their left hand for zero and right for one.The first persons computer recogonizes these binary codes.Now these are send to the second person's computer via internet.And it is either send to second person by using lamps of definite frequencies or directly to brain via impulse.
This is to change our world to an extand lets hope it does.
