To Mr Jobs's delight, the iPod's market share has grown from about one-third to two-thirds in the past year, at the expense of much cheaper "flash" players (iPods use hard discs to store music, rather than flash-memory cards).
Sensor outputs were continuously recorded on a hard disc at a sampling rate of 200 Hz with a resolution of 24 bits.
This type of file compression system enables the user to conserve hard disc space without having to compress files one at a time.
It was a long time coming but you can finally connect an external hard disc drive (HDD) to your PlayStation 4 (PS4) or PS4 Pro.
Spike waveforms (300 Hz−10 kHz bandpass) were sampled continuously at 25 kHz, and saved to hard disc together with LFPs sampled from the same electrodes at 500 Hz (1 100 Hz bandpass), lever position, M1 LFPs (bandpass 1 100 Hz, sampling rate 500 Hz, inverting amplifier, negativity upwards) and task behavioural markers.
Who has not watched Windows crash and reboot without provocation, downloaded endless anti-virus programs to reclaim a moribund hard disc, fiddled with cables and settings to hook up a printer, and sometimes simply given up?
A hydrophone (Brüel & Kjaer 8106, sensitivity -174 dB re 1 V per l Pa) was positioned about 5 cm off the center of the aquarium and connected to a microphone power supply (Brüel & Kjaer 2804) whose output was sent to the hard disc recorder.
Just as cloud-technologies like Dropbox have allowed users to store their files without needing large hard discs, Frame hopes to further enable mobile users by allowing them to essentially outsource their computing power and run graphics-intensive applications inside a browser.
Data are accessed through the internet; programs are opened in browser windows rather than loaded from the hard disc; instant messages, often attached to social-networking sites such as Facebook, replace e-mail.
