FDC board from an IBM 5150.The NEC D765AC FDC IC is the large dual in-line package at the top.. A floppy-disk controller (FDC) is a hardware component that directs and controls reading from and writing to a computer's floppy disk drive (FDD).
Open Host Controller Interface (OHCI) [1] is an open standard.. Die shot of a VIA VT6307 Integrated Host Controller used for IEEE 1394A communication. When applied to an IEEE 1394 (also known as FireWire; i.LINK or Lynx) card, OHCI means that the card supports a standard interface to the PC and can be used by the OHCI IEEE 1394 drivers that come with all modern operating systems.
3.5-inch and 5.25-inch drives connect to the floppy controller using a 34-conductor flat ribbon cable for signal and control; a separate cable provides d.c. power. Most controllers support two floppy drives, so a cable could have 5.25-inch style connectors, 3.5-inch style connectors, or a combination.
In computing, an optical disc drive (ODD) is a disc drive that uses laser light or electromagnetic waves within or near the visible light spectrum as part of the process of reading or writing data to or from optical discs. Some drives can only read from certain discs, while other drives can both read and record.
Zellweger is the brand name of an electric switching device also known as a Ripple Control Receiver used to control off-peak electrical loads such as water heaters by switching these loads OFF over peak energy use times of the day and switching them ON after peak energy use times of the day, hence the term 'off peak' control.
A switched-mode power supply operating at the current limit with the output short-circuited does not have increased power dissipation in the power transistor(s), so foldback current limiting is an application feature only rather than one that also prevents a load fault from also destroying the power supply. The safety benefit of reducing the ...
On today's episode of The College Football Enquirer, Dan Wetzel, Ross Dellenger and SI's Pat Forde unpack the latest chaos created by the transfer portal. Specifically, they cover Penn State ...
NEC is related to the Australian concept of Ubiquitous Command and Control (UC2), which includes network-enabled capability, military intent, and awareness. UC2 extends the "networking position" of NEC and NCW to include positions on decision devolution, seeking the ubiquity of available decision makers and using computing to achieve it, the ...
