refresh rate

Reviews The refresh rate, expressed in hertz (Hz), is determined by the computer's video card. The higher the refresh rate, the easier the monitor is to view -- rates lower than 75Hz can produce irritating screen flicker.

bit rate

Reviews In data communications, the bit rate is the measure of how many bits of data are transmitted or received (say, from a modem) in a specified amount of time, such as kilobits per second (Kbps). Generally speaking, a low bit rate means lower sound...

Sharp Aquos LC32RD2E review

Reviews Put simply, the technology doubles the screen's refresh rate so that individual images are replaced more quickly while eliminating the pauses in between. Using 100Hz scanning to speed up the refresh rate from 8ms to 4ms reduces this lag to create...

How does an MP3 player work?

Reviews The sound depends on two factors: the quality of this compression algorithm and the bit rate at which the song is encoded, measured in Kbps. In order to turn an analogue signal (such as one picked up by a standard microphone) into a digital stream...

Moore's law

Reviews In a 1965 article for Electronics magazine, Moore observed that the number of transistors per square inch on integrated circuits (a measure of computer processing power) had increased by a factor of two every year since the integrated circuit was...

Arcam DiVA DT-91 review

Reviews One reason to listen to DAB, despite its sub-par bit rate, is the sheer choice of stations. Given the low bit rate of DAB, you're unlikely to hear a massive improvement over the phono interconnects, but you will eliminate potential problems with...

SanDisk Digital Audio Player (1GB, silver) review

Reviews It also packs in a wealth of information, including track number, elapsed time, a battery gauge, file-format and bit-rate icons, and even a level meter. In our tests, files zipped from PC to player at the impressive rate of 6.54MB per second.

Nvidia GeForce 8800 GTX review

Reviews That memory rate is a significant upgrade compared to the 800MHz RAM in Nvidia's last flagship card, the GeForce 7950 GX2. The GeForce 8800 GTX has a core clock speed of 575MHz, and it comes with 768MB of DDR3 RAM clocked to 900MHz with a 1,800MHz...

Sharp LC37RD2E review

Reviews Using electronics to artificially increase the refresh rate is designed to decrease the amount of blurring and motion judder you see. How much you rate this feature will depend on how much you like the 'feel' of film.

JVC Everio GZ-HD7 review

Reviews The first, 1,920x1,080 pixels, dubbed 'FHD' for 'Full HD', uses variable bit rate compression for a theoretically better picture. The second, 1,440x1,080 pixels, dubbed '1440 CBR' uses constant bit rate compression, and is the HD format you must...

Kodak EasyShare C533 review

Reviews We recorded a shot-to-shot rate of 1.8 seconds, which increased to just 2.3 seconds with the flash enabled. We could fire off bursts of only 3 shots at a time, at a rate of 2.7fps. The Kodak EasyShare C533 is a basic budget camera that doesn't...

Canon PowerShot A460 review

Reviews This would be a decent score for a 6- or 7-megapixel camera, but we expected a faster rate for a mere 5-megapixel shooter. We shot 47 full-resolution images in 31 seconds for a rate of 1.5fps. Plenty of snapshot cameras cost less than £150, and you...
