Spooling' describes the operation of dumping the information to be printed onto disk or tape, allowing the computer to get on with its next task while the dumped information waits its turn to be printed at a time when the computer is less busy. This process is handled by 'print spooler' software. At room temperature, even a good conductor such as the copper used in PCBs has electrical resistance - that is, it offers some opposition to the flow of electrical current. If the copper were cooled to around - 273C it would lose all resistance and become a superconductor, but you would have to sit in a vat of liquid nitrogen to operate your computer. In recent years, the race has been on to find substances that exhibit superconductivity at higher temperatures.
Squids are super conducting devices that are extremely sensitive to the tiniest magnetic fields.
They hope that this will lead to the first 'thought-controlled' computer interface. Return SQL Structured Query Language. Pronounced 'sequel' or as initials, depending who you talk to. A way of asking questions about data from a database, SQL is defined by ANSI and enables any SQL-compliant database to be 'interrogated' by any application that can issue SQL commands. A device called an 'SR flip-flop' forms the basic storage unit of SRAM memory chips.
