Sosumi is an alert sound introduced by Apple sound designer Jim Reekes in Apple Inc.'s Macintosh System 7 operating system in 1991. The name is derived from the phrase "so, sue me!" because of a long running court battle with Apple Corps, the similarly named music company, regarding the use of music in Apple Inc.'s computer products.
The Macintosh startup chime is played on power-up, before booting into an operating system. The sound indicates that diagnostic tests were run immediately at startup and have found no hardware or fundamental software problems. [9] The specific sound differs depending on the ROM, which greatly varies depending on Macintosh model.
Also, it was difficult for programs to do much else, even update the display, during the playing of such sounds. Thus, when sound cards (which can output complex sounds independent from the CPU once initiated) became mainstream in the PC market after 1990, they quickly replaced the PC speaker as the preferred output device for sound effects.
Different types of noise are generated by different devices and different processes. Thermal noise is unavoidable at non-zero temperature (see fluctuation-dissipation theorem), while other types depend mostly on device type (such as shot noise, [1] [3] which needs a steep potential barrier) or manufacturing quality and semiconductor defects, such as conductance fluctuations, including 1/f noise.
Noise, static or snow screen captured from a blank VHS tape. Noise, commonly known as static, white noise, static noise, or snow, in analog video, CRTs and television, is a random dot pixel pattern of static displayed when no transmission signal is obtained by the antenna receiver of television sets and other display devices.
This memory location typically contains a jump instruction that transfers execution to the location of the firmware (UEFI or BIOS) start-up program. This program runs a power-on self-test (POST) to check and initialize required devices such as main memory ( DRAM ), the PCI bus and the PCI devices (including running embedded Option ROMs ).

Computer speakers, or multimedia speakers, are speakers sold for use with computers, although usually capable of other audio uses, e.g. for an MP3 player. Most such speakers have an internal amplifier and consequently require a power source, which may be by a mains power supply often via an AC adapter , batteries, or a USB port.
