Ultrabooks are a new category of notebook computers that seeks to fill the gap between lightweight laptops and tablets. Intel dubbed the ultrabook category when it announced it would be directing its mobile computing efforts towards a new class of laptops that would offer an extremely thin (less than 20 millimeters, or 0.8 inches) and lightweight profile to go along with high-powered, low voltage processors in the Sandy Bridge or Ivy Bridge families, long battery life, near instant-on and instant-resume capabilities, and fast storage, typically via solid state disk drives (SSDs), all in a sub $1,000 package.
Ultrabooks are distinguished from netbooks by offering more power in the form of faster processors and additional RAM, as well as better storage and larger screen sizes, features that also make these laptops significantly more expensive than most netbooks. Ultrabook prices are expected to come down, though, as Intel transitions to its “Hawell” system-on-a-chip (SoC) processors, at which point Intel predicts ultrabook prices will reach the sub $600 price range.
(ul´´-tra-p��rt´&-b&l) (n.) A class of laptop computer that is designed around its portability. Ultraportables typically weigh less than four pounds and, when closed, are 1.5″ thin or thinner. A common ultraportable also will have wireless networking capabilities, can have an internal optical drive, and capabilities to connect to an external storage device. Since the devices […]
- ultrasonic focus motor
Abbreviated as USM, and associated with digital camera terminology, ultrasonic motor (also called ultrasonic focus motor ) is a term that is mainly used to describe the motor that controls the movement of the lens or focus ring. An ultrasonic focus motor is much quieter (almost near-silent) and also moves the focus lens or ring […]
Short for Ultra Wide Band, a wireless communications technology that can currently transmit data at speeds between 40 to 60 megabits per second and eventually up to 1 gigabit per second. UWB transmits ultra-low power radio signals with very short electrical pulses, often in the picosecond (1/1000th of a nanosecond) range, across all frequencies at […]
- uncompressed video
Captured video that has not been altered by the capture device or software to compress the data. Uncompressed video streams take up a lot of disk space and more transmission bandwidth but it provides the best quality.
To return to a previous state by undoing the effects of one or more commands. The undo command is a valuable feature supported by many software products. It lets you try unknown commands with less risk, because you can always return to the previous state. Also, if you accidentally press the wrong function key, you […]
