Long life laptop Battery..

  By Intel:

Laptops enable you to connect, play and work wherever and whenever you want. But if you lose battery power and can't plug in on the go, your laptop is no better than an over sized coaster. With advances in processor architecture and mobile-optimized technologies and software, you can experience a near-desktop experience for playing games, listening to and downloading music, and surfing the Internet — all without being leashed to the nearest outlet. But even with these built-in, mobile-optimized technologies, you may still have to plug in before you're ready. To squeeze every last drop of power out of your laptop battery, follow these tip and tricks and you'll stay mobile longer:

 

1. Charge the battery! Consider keeping it plugged in for 12 hours before you unplug.

Tip! Over time, you may find that you have to recharge your battery more often to get the expected level of performance. If that’s the case, it’s time to replace your battery. Look for lithium ion (Li-Ion) replacement batteries for the greatest longevity.

2. Switch on the optimized battery or power feature. You’ll find this option — sometimes referred to as max battery mode — in your laptop system’s built-in power management control panel. You can select the option to reduce the amount of time your inactive laptop stays on before powering itself down and going to sleep.

Tip! Turning off power-draining facilities like backlights can preserve quite a bit of battery life.

3. Check to see if your laptop has the optimum amount of RAM. You can do this by right mouse clicking on My Computer. The amount of RAM you have will appear under your System Information. RAM enables your system to run program instructions using the computer’s memory instead of its hard disk drive (HDD), where it stores data. Refreshing the RAM requires less power than spinning the hard drive, so having the correct amount of RAM means less drain on your laptop battery.

Tip! Consider 2 GB or more RAM for the best performance!

4. Remove the battery and clean the metal contacts. Wipe them with alcohol, ideally every two months, to ensure that the power transfer between the laptop and its battery is as efficient as possible. Allow the battery to dry thoroughly before replacing it!

5. Unplug any laptop accessories you aren’t using. Even if they’re not in use, accessories drain power from the battery.
Tips!
Turn your wireless local area network (WLAN) switch off if you don’t need a wireless connection — a button or LED on your laptop usually lights up to indicate wireless activities.
Use your laptop in the best possible lighting conditions. In brighter conditions, you won’t need to set your laptop screen to maximize brightness so you can save additional battery life.

6. Defragment the hard drive so your system operates as efficiently as possible. The built-in defragmenting utility included with Windows®*-based operating systems decreases the time your system must spend searching for files by rearranging file fragments, so they are closer together on the hard drive. Less time searching means less spinning for the hard drive and less use of battery power.

Tip! Defragment your hard drive at least every two months!

Follow these battery-saving tips and tricks and you’ll be well on your way to staying unleashed longer!Resources

What is mouse?

Introduction to the mouse

The mouse is a pointing device used to move a cursor on the screen and allowing objects to be selected, moved and manipulated using the buttons. The consistent action of pressing (clicking) on a button in order to carry out an action is called a "click".

The first mouse was invented and developed by Douglas Carle Engelbart of the Stanford Research Institute (SRI): it was a wooden mouse containing two perpendicular discs and connected to the computer by a pair of twisted wires.
Mouse connector

The mouse is generally plugged in to the back of the central processing unit, into the motherboard, with a green PS/2 connector:



Some mice, with advanced functionalities sometimes have a USB connector.
Types of mice

There are several types of mice, classified according to the positioning technology on the one hand and the data transmission to the central processing unit on the other.

We can therefore distinguish several large categories of mice:
Mechanical mice, where the operation is based on a ball (in plastic or rubber) encased in a frame (in plastic) transmitting the movement to two rollers;
Optical-mechanical mice, where the operation is similar to that of mechanical mice, except the movement of the ball is detected by optic sensors.
Optical mice, capable of determining movement through visual analysis of the surface upon which they slide.
Mechanical mouse

The mechanical mouse comprises of a ball upon which two rollers turn. These rollers each comprise of a notched disc which turns between a photodiode and LED (Light Emitting Diode) allowing the light to pass through in sequence. When the light passes through, the photodiode sends a bit (1), when it meets an obstacle, the photodiode sends a zero bit (0). Using this information, the computer knows the position of the cursor and even its speed.



Tip: As you use it, dust settles on the mouse rollers preventing them from turning correctly and causing strange reactions in the cursor. To remedy this, simply open the cage containing the ball and clean the rollers (with a toothbrush for example).
Optical mouse

The optical mouse operates by analysing the surface on which it moves. So, an optical mouse is comprised of an LED, an image acquisition system (IAS) and a digital signal processor (DSP).

The LED is responsible for shining on the surface so as to enable the IAS to get an image of the surface. The DSP, through analysing the microscopic characteristics of the surface determines the horizontal and vertical movement.

Optical mice operate on any slightly uneven or even coloured surface. The main advantages of this type of pointing device in comparison to the mechanical mouse are greater precision along with less dirtiness.
Cordless mouse

Cordless mice are more and more popular because they can be used without physically being connected to the computer, which gives a sensation of freedom.

There are also several categories of cordless mice, depending on the technology used:
Infrared mouse (IR) these mice are used with an infrared receiver connected to the computer. The range of this type of device is a few metres at most with direct line of sight in the same way as a television remote.
Hertzian mouse: these mice are used with a hertzian receiver, generally proprietary to the manufacturer. The range of this type of device is around ten metres at most, not necessarily with direct line of sight to the computer. This type of device can be practical for people connecting their computer to their television in another room.
Bluetooth mouse: these mice are used with a Bluetooth receiver connected to the computer. The range of this type of device is the same as the propriety hertzian technologies.
Mouse wheel

Mice are increasingly equipped with a wheel. The wheel, generally located between the right and left buttons makes it possible to scroll through pages while enabling the user to move the cursor on the screen.

What is Key board?

Key Board:-

The most commonly and usually used input device which you see in every house with computer is keyboard and mouse.

Keyboard is an electonic input device and is used to enter data into the CPU for processing.It is a typewriter like device.All keyboards have no. ,keys, punctuation keys,and  a space bar.They also have functionkeys,numeric ketpad,arrow keys, and certain additional keys kile page-up,page-down, home,end etc.

The Qwerty keyboard was designed in 1868 in Milwaukee by Christopher Latham Sholes, who placed the keys corresponding to the most commonly used letter pairs at opposite ends of the keyboard, in order to prevent the typewriter hammers of the time from becoming jammed with one another. This keyboard was first sold by the company Remington in 1873. Therefore, the Qwerty keyboard was designed from a purely technical perspective, hindering usability and efficienc

Types of keyboards


There are four types of keyboards for PCs. The first three were invented by IBM, while the latter is the result of changes made when Microsoft Windows 95 was released. These are the four kinds of keyboards:

The 83-key keyboard (PC/XT)






The 84-key keyboard (PC/AT)

The 102-key keyboard, called the extended keyboard

The 105-key Microsoft Windows 95-compatible keyboard.


Division of keyboard:-

Standard key.
Numeric keys
Arrow keys.
function keys.

PCI Slot and sound card

The photo above shows what a PCI slot looks like. PCI slots can handle 64 bits of data at a time. ISA slots can only handle 32 bits of data at a time. PCI stands for "Peripheral Component Interconnect." A 64-bit PCI slot has 64 connections to the motherboard. Each connection is capable of handling 1 bit of data at a time. A 32-bit ISA slot has 32 connections to the motherboard and can handle only 32 bits of data at a time. Below is a picture of how a PCI card is installed.

Note: Older technology ISA slots were 8-bit and 16-bit. The later EISA, (or Extended ISA), slots are capable of 32-bit data transfer. Older PCI technology was 32-bit. The newer PCI technology is 64-bit.

Below is a picture of Creative's Sound Blaster Live Value PCI sound card. The sound card is what processes a computer's sound data. When you hear music coming from your computer's speakers, the sound card's digital signal processor, (or DSP), is at work along with the digital-to-analog converter, (or DAC), processing and converting digital sound data to analog sound data. When you talk into your computer's microphone, the sound card's DSP works along with the analog-to-digital converter, (or ADC), to process and convert analog sound data to digital sound data. Analog audio is continuous, like the sound waves from a person's voice. Digital audio is broken into pieces that the computer can understand and work with. Better sound cards have better sound. The Sound Blaster Live Value card allows you to connect a sound input device (like a stereo), a microphone, front speakers, rear speakers, and a joystick or MIDI instrument (like a MIDI keyboard). The front and rear speakers can be combined together to produce stereo surround sound. Just like the video card, the sound card uses its own processor to process sound data.

Sun is the acronym for Stanford University Network.

Sun Microsystems was founded by four Stanford University buddies,

3: Yahoo!

This word was thought by Jonathan Swift and used in his book Gulliver's Travels. It represents a person who is repulsive in appearance and action and is barely human. Yahoo! founders Jerry Yang and David Filo selected the name because they considered themselves yahoos.

4: Xerox

The Greek root "xer" means dry. The inventor, Chestor Carlson , named his product Xerox as it was dry copying, markedly different from the then prevailing wet copying.

5: Sony

From the Latin word 'sonus' meaning sound, and 'sonny' a slang used by Americans to refer to a bright youngster.

6: Red Hat

Company founder Marc Ewing was given the Cornell lacrosse team cap (with red and white stripes) while at college by his grandfather. He lost it and had to search for it desperately. The manual of the beta version of Red Hat Linux had an appeal to readers to return his Red Hat if found by anyone!

7: Oracle

Larry Ellison and Bob Oats were working on a consulting project for the Central Intelligence Agency (CIA). The code name for the project was called Oracle (the CIA saw this as the system to give answers to all questions or something such).

Bill Hewlett and Dave Packard tossed a coin to decide whether the company they founded would be called Hewlett-Packard or Packard-Hewlett.

Robot Engages Novice Computer Scientists

Learning how to program a computer to display the words "Hello World" once may have excited students, but that hoary chestnut of a lesson doesn't cut it in a world of videogames, smartphones and Twitter. One option to take its place and engage a new generation of students in computer programming is a Carnegie Mellon University-developed robot called Finch.

A product of CMU's famed Robotics Institute, Finch was designed specifically to make introductory computer science classes an engaging experience once again.

A white plastic, two-wheeled robot with bird-like features, Finch can quickly be programmed by a novice to say "Hello, World," or do a little dance, or make its beak glow blue in response to cold temperature or some other stimulus. But the simple look of the tabletop robot is deceptive. Based on four years of educational research sponsored by the National Science Foundation, Finch includes a number of features that could keep students busy for a semester or more thinking up new things to do with it.


"Students are more interested and more motivated when they can work with something interactive and create programs that operate in the real world," said Tom Lauwers, who earned his Ph.D. in robotics at CMU in 2010 and is now an instructor in the Robotics Institute's CREATE Lab. "We packed Finch with sensors and mechanisms that engage the eyes, the ears -- as many senses as possible."

Lauwers has launched a startup company, BirdBrain Technologies, to produce Finch and now sells them online at www.finchrobot.com for $99 each.

"Our vision is to make Finch affordable enough that every student can have one to take home for assignments," said Lauwers, who developed the robot with Illah Nourbakhsh, associate professor of robotics and director of the CREATE Lab. Less than a foot long, Finch easily fits in a backpack and is rugged enough to survive being hauled around and occasionally dropped.

Finch includes temperature and light sensors, a three-axis accelerometer and a bump sensor. It has color-programmable LED lights, a beeper and speakers. With a pencil inserted in its tail, Finch can be used to draw pictures. It can be programmed to be a moving, noise-making alarm clock. It even has uses beyond a robot; its accelerometer enables it to be used as a 3-D mouse to control a computer display.

Robot kits suitable for students as young as 12 are commercially available, but often cost more than the Finch, Lauwers said. What's more, the idea is to use the robot to make computer programming lessons more interesting, not to use precious instructional time to first build a robot.

Finch is a plug-and-play device, so no drivers or other software must be installed beyond what is used in typical computer science courses. Finch connects with and receives power from the computer over a 15-foot USB cable, eliminating batteries and off-loading its computation to the computer. Support for a wide range of programming languages and environments is coming, including graphical languages appropriate for young students. Finch currently can be programmed with the Java and Python languages widely used by educators.

A number of assignments are available on the Finch Robot website to help teachers drop Finch into their lesson plans, and the website allows instructors to upload their own assignments or ideas in return for company-provided incentives. The robot has been classroom-tested at the Community College of Allegheny County, Pa., and by instructors in high school, university and after-school programs.

"Computer science now touches virtually every scientific discipline and is a critical part of most new technologies, yet U.S. universities saw declining enrollments in computer science through most of the past decade," Nourbakhsh said. "If Finch can help motivate students to give computer science a try, we think many more students will realize that this is a field that they would enjoy exploring."
