The concept of CPU-bounding was developed during early computers, when data paths between computer components were simpler, and it was possible to visually see one component working while another was idle. Example components were CPU, tape drives, hard disks, card-readers, and printers.
The first HDD RAMAC and most early disk drives used complex mechanisms to load and unload the heads. Nearly all modern HDDs use ramp loading, first introduced by Memorex in 1967, [9] to load/unload onto plastic "ramps" near the outer disk edge. Laptop drives adopted this due to the need for increased shock resistance, and then ultimately it was ...
Tandy/Radio Shack TRS-80 Model I. In the mid-1970s, Tandy Corporation's Radio Shack division was a successful American chain of more than 3,000 electronics stores. Among the Tandy employees who purchased a MITS Altair kit computer was buyer Don French, who began designing his own computer and showed it to the vice president of manufacturing John V. Roach, Tandy's former electronic data ...
As one of the first widely available processors with a 32-bit instruction set, large unsegmented address space, and relatively high speed for the era, the 68k was a popular design through the 1980s. It was widely used in a new generation of personal computers with graphical user interfaces , including the Macintosh 128K , Amiga , Atari ST , and ...
Over time, popular usage extended the word firmware to denote any computer program that is tightly linked to hardware, including BIOS on PCs, boot firmware on smartphones, computer peripherals, or the control systems on simple consumer electronic devices such as microwave ovens and remote controls.
In computer architecture, frequency scaling (also known as frequency ramping) is the technique of increasing a processor's frequency so as to enhance the performance of the system containing the processor in question.
NetBSD is a free and open-source Unix-like operating system based on the Berkeley Software Distribution (BSD). It was the first open-source BSD descendant officially released after 386BSD was forked.
Beginnings are expensive, so be specific in the matching of the first few characters to eliminate possibilities quickly. If possible don't use the quantifiers * and + with anything but a single character. Avoid them entirely if possible, as they put extra strain on CPU and are apt to do other than what you expect.
