 LAPTOP parts

A laptop computer, usually called a notebook computer by manufacturers, is a battery- or AC-powered personal computer generally smaller than a briefcase that can easily be transported and conveniently used in temporary spaces such as on airplanes, in libraries, temporary offices, and at meetings. A laptop typically weighs less than 5 pounds and is 3 inches or less in thickness. Among the best-known makers of laptop computers are IBM, Apple, Compaq, Dell, and Toshiba.

Laptop computers generally cost more than desktop computers with the same capabilities because they are more difficult to design and manufacture. A laptop can effectively be turned into a desktop computer with a docking station, a hardware frame that supplies connections for peripheral input/output devices such as a printer or larger monitor. The less capable port replicator allows you to connect a laptop to a number of peripherals through a single plug.

Laptops usually come with displays that use thin-screen technology. The thin film transistor or active matrix screen is brighter and views better at different angles than the STN or dual-scan screen. Laptops use several different approaches for integrating a mouse into the keyboard, including the touch pad, the trackball, and the pointing stick. A serial port also allows a regular mouse to be attached. The PC Card is insertable hardware for adding a modem or network interface card to a laptop. CD-ROM and digital versatile disc drives may be built-in or attachable.

 Videophone tv”Did you mean”

A videophone is a telephone with a video screen, and is capable of full duplex (bi-directional) video and audio transmissions for communication between people in real-time. It was the first form of videotelephony, later to be followed by videoconferencing, webcams, and finally telepresence.

At the dawn of the technology, videotelephony also included image phones which would exchange still images between units every few seconds over conventional POTS-type telephone lines, essentially the same as slow scan TV systems.

Currently videophones are particularly useful to the deaf and speech-impaired who can use them with sign language, and also with video relay services to communicate with hearing persons. Videophones are also very useful to those with mobility issues or those who are located in distant places and are in need of telemedical or tele-educational services.

 Tablet computer”Did you mean”
A tablet computer, or simply tablet, is a complete personal mobile computer, larger than a mobile phone or personal digital assistant, integrated into a flat touch screen and primarily operated by touching the screen. It often uses an onscreen virtual keyboard or a digital pen rather than a physical keyboard.

The term may also apply to a "convertible" notebook computer whose keyboard is attached to the touchscreen by a swivel joint or slide joint so that the screen may lie with its back upon the keyboard, covering it and exposing only the screen for touch operation.

Releases KODAK camcorder

In 1984, Kodak introduced the first camcorder. A year later Sony introduced the first HandyCam model (but nowadays, a handycam is a generic name, because is used by other companies, like Panasonic).

A camcorder is a portable electronic device (generally a digital camera) for recording images and audio onto a storage device. The camcorder contains both camera and recorder in one unit, hence its portmanteau name. This compares to previous technology where they would be separate. Video cameras were originally designed for broadcasting television images--see television camera.

Video is captured by way of the camera lens, and is sent to a CCD (charge-coupled device), possibly processed, compressed, and then to final storage.

We can generally distinguish between digital and analog camcorders. The market share for digital models is continually increasing, as models become cheaper and better quality. Any recent Personal Computer can be made into a digital video editing machine with the use of digital editing software - a light version with limited features is often included with digital cameras.

There are various storage devices and respective formats for camcorders, please see the video page for details. The latest camcorders also record on a flash memory device (in MPEG-1, MPEG-2 or MPEG-4) or directly on DVD (either DVD-RAM or DVD-R) in MPEG-2 format. Other digital tape recorders transfer their video content in DV format over a IEEE 1394 connection to a computer, where the huge files (approx. 2GB for 5 minutes on PAL DVD resolution) need to be edited and compressed or played back on tape. The transfer speed is currently 1x, which means one hour footage needs one hour to transfer.

Besides classification in analog and digital camcorders, they can also be classified by consumer products, semi-professional products and broadcast quality products. Product cycles are 6-12 months, 2-4 years and 5+ years respectively. They can also be used to record personal events for future reminiscing, or even as an artistic tool.

 Feature ‘did you mean’camera digital

A camera that stores images digitally rather than recording them on film. Once a picture has been taken, it can be downloaded to a computer system, and then manipulated with a graphics program and printed. Unlike film photographs, which have an almost infinite resolution, digital photos are limited by the amount of memory in the camera, the optical resolution of the digitizing mechanism, and, finally, by the resolution of the final output device. Even the best digital cameras connected to the best printers cannot produce film-quality photos. However, if the final output device is a laser printer, it doesn't really matter whether you take a real photo and then scan it, or take a digital photo. In both cases, the image must eventually be reduced to the resolution of the printer.

The big advantage of digital cameras is that making photos is both inexpensive and fast because there is no film processing. Interestingly, one of the biggest boosters of digital photography is Kodak, the largest producer of film. Kodak developed the Kodak PhotoCD format, which has become the de facto standard for storing digital photographs.

Most digital cameras use CCDs to capture images, though some of the newer less expensive cameras use CMOS chips instead.

Best Refrigerator

A refrigerator (commonly called a "fridge") is a cooling apparatus. The common household appliance comprises a thermally insulated compartment and a heat pump—chemical or mechanical means—to transfer heat from it to the external environment (i.e., the room in which it is located), cooling the contents to a temperature below ambient. Cooling is a popular food storage technique in developed countries and works by decreasing the reproduction rate of bacteria. The device is thus used to reduce the rate of spoilage of foodstuffs.

A refrigerator maintains a temperature a few degrees above the freezing point of water. Optimum temperature range for perishable food storage is 3 to 5 °C (37 to 41 °F).^[1] A similar device which maintains a temperature below the freezing point of water is called a "freezer".

The refrigerator is a relatively modern invention among kitchen appliances. It replaced the icebox, which had been a common household appliance for almost a century and a half prior. For this reason, a refrigerator is sometimes referred to as an "icebox".

Best Microwave oven

 Best  Microwave oven

microwave oven, device that uses microwaves to rapidly cook food. The microwaves cause water molecules in the food to vibrate, producing heat, which is distributed through the food by induction. A special electron tube called a magnetron produces the microwaves. Typical output power for consumer devices ranges from 650 to 1200 watts. To ensure even heating, the magnetron directs its waves at a rotating metal disk with offset vanes, which scatters the waves through the oven cavity; a rotating platform for the food is sometimes used in addition. Power settings may reduce the amount of radiation by cycling a constant-output magnetron on and off for varying lengths of time, or may reduce the level of radiation constantly produced by an inverter magnetron. The magnetron may be supplemented by quartz and halogen bulbs for browning food, which microwaves do poorly.

In 1993, two optical disc storage formats were being developed. One was the MultiMedia Compact Disc (MMCD) also called CDi, backed by Philips and Sony, Panasonic Samsung TDK 20th Century Fox Sony Pictures Entertainment and the other was the Super Density (SD) disc, supported by Toshiba, Time Warner, Matsushita Electric, Hitachi, Mitsubishi Electric, Pioneer, Thomson, and JVC.

Representatives of the SD camp approached IBM, asking for advice on the file system to use for their disc as well as seeking support for their format for storing computer data. Alan E. Bell, a researcher from IBM's Almaden Research Center received that request and also learned of the MMCD development project. Wary of being caught in a repeat of the costly videotape format war between VHS and Betamax in the 1980s, he convened a group of computer industry experts, including representatives from Apple, Microsoft, Sony,Sun, Dell, and many others. This group was referred to as the Technical Working Group, or TWG.

The TWG voted to boycott both formats unless the two camps agreed on a single, converged standard.^[5] Lou Gerstner, president of IBM, was recruited to apply pressure on the executives of the warring factions. Eventually, the computer companies won the day, and a single format, now called DVD, was agreed upon. The TWG also collaborated with the Optical Storage Technology Association (OSTA) on the use of their implementation of the ISO-13346 file system (known as Universal Disc Format [UDF] for use on the new DVDs.

Philips and Sony and Panasonic and Samsung all decided it was in their best interest to avoid another format war over their MultiMedia Compact Disc, and agreed to unify with companies backing the Super Density Disc to release a single format with technologies from both. The specification was mostly similar to Toshiba and Matsushita's Super Density Disc, except for the dual-layer option (MMCD was single-sided and optionally dual-layer, whereas SD was single-layer but optionally double-sided) and EFMPlus modulation.

EFMPlus was chosen because of its great resilience to disc damage, such as scratches and fingerprints. EFMPlus, created by Kees Immink (who also designed EFM), is 6% less efficient than the modulation technique originally used by Toshiba, which resulted in a capacity of 4.7 GB, as opposed to the original 5 GB. The result was the DVD specification, finalized for the DVD movie player and DVD-ROM computer applications in December 1995.

The DVD Video format was first introduced by Toshiba in Japan in November 1996, in the United States in March 1997 (test marketed),^[6] in Europe in October 1998, and in Australia in February 1999.

In May 1997, the DVD Consortium was replaced by the DVD Forum, which is open to all other companies.

DVD, also known as Digital Versatile Disc, is an optical disc storage media format, and was invented and developed by Philips, Sony, Panasonic Samsung Toshiba,20th Century Fox] and Warner Bros in 1995. Its main uses are video and data storage. DVDs are of the same dimensions as compact discs (CDs), but are capable of storing almost seven times as much data.

Variations of the term New DVD often indicate the way data is stored on the discs: DVD-ROM (read only memory) has data that can only be read and not written; DVD-R and DVD+R (recordable) can record data only once, and then function as a DVD-ROM; DVD-RW (re-writable), DVD+RW, and DVD-RAM (random access memory) can all record and erase data multiple times. The wavelength used by standard DVD lasers is 650 nm;^[4] thus, the light has a red color.

DVD media is used in DVD-Video consumer digital video format and in DVD-Audio consumer digital audio format, as well as for authoring AVCHD discs. DVD media containing other types of information may be referred to as DVD data discs.

 Electronic book
An electronic book (also e-book, ebook, digital book) is a text and image-based publication in digital form produced on, published by, and readable on computers or other digital devices. Sometimes the equivalent of a conventional printed book, e-books can also be born digital. The Oxford Dictionary of English defines the e-book as "an electronic version of a printed book," but e-books can and do exist without any printed equivalent. E-books are usually read on dedicated hardware devices known as e-Readers or e-book devices. Personal computers and some cell phones can also be used to read e-books.

 Best HD DVD”Did you mean”
HD DVD (short for High-Definition/Density DVD) is a discontinued high-density optical disc format for storing data and high-definition video.^[1] Supported principally by Toshiba, HD DVD was envisioned to be the successor to the standard DVD format. However, in February 2008, after a protracted high definition optical disc format war with rival Blu-ray, Toshiba abandoned the format, announcing it would no longer develop or manufacture HD DVD players or drives. However, the HD DVD physical disk specifications (but not the codecs) are still in use as the basis for the CBHD (China Blue High-Definition Disc) formerly called CH-DVD. The HD DVD Promotion Group was dissolved on March 28, 2008.
