List Of The Oldest Currently Registered Internet Domain Names
This is a list of the oldest extant registered generic top-level domains used in the Domain Name System of the Internet. Until late February 1986, Domain Registration was limited to organizations with access to ARPA. Public registration was revealed on USEnet on Feb 24, 1986. .com .org .edu Registration within .edu is restricted to accredited educational institutions. Prior to October 2001, registration was available worldwide; it has since been limited to institutions based in the United States. .net .mil .gov .int .arpa {, class="wikitable sortable" , - !Rank !!

Generic Top-level Domains
Generic top-level domains (gTLDs) are one of the categories of top-level domains (TLDs) maintained by the Internet Assigned Numbers Authority (IANA) for use in the Domain Name System of the Internet. A top-level domain is the last level of every fully qualified domain name. They are called generic for historical reasons; initially, they were contrasted with country-specific TLDs in RFC 920. The core group of generic top-level domains consists of the com, net, org, biz, and info domains. In addition, the domains name, and pro are also considered ''generic''; however, these are designated as ''restricted'', because registrations within them require proof of eligibility within the guidelines set for each. Historically, the group of generic top-level domains included domains, created in the early development of the domain name system, that are now sponsored by designated agencies or organizations and are restricted to specific types of registrants. Thus, domains edu, gov, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alpha Communications Development Corporation
Alpha (uppercase , lowercase ; grc, ἄλφα, ''álpha'', or ell, άλφα, álfa) is the first letter of the Greek alphabet. In the system of Greek numerals, it has a value of one. Alpha is derived from the Phoenician letter aleph , which is the West Semitic word for " ox". Letters that arose from alpha include the Latin letter A and the Cyrillic letter А. Uses Greek In Ancient Greek, alpha was pronounced and could be either phonemically long ( ː or short ( . Where there is ambiguity, long and short alpha are sometimes written with a macron and breve today: Ᾱᾱ, Ᾰᾰ. * ὥρα = ὥρᾱ ''hōrā'' "a time" * γλῶσσα = γλῶσσᾰ ''glôssa'' "tongue" In Modern Greek, vowel length has been lost, and all instances of alpha simply represent the open front unrounded vowel . In the polytonic orthography of Greek, alpha, like other vowel letters, can occur with several diacritic marks: any of three accent symbols (), and either of two breathing marks ...

Pyramid Technology
Pyramid Technology Corporation was a computer company that produced a number of RISC-based minicomputers at the upper end of the performance range. It was based in the San Francisco Bay Area of California They also became the second company to ship a multiprocessor UNIX system (branded DC/OSx), in 1985, which formed the basis of their product line into the early 1990s. Pyramid's OSx was a dual-universe UNIX which supported programs and system calls from both 4.xBSD and AT&T's UNIX System V. History Pyramid Technology was formed in 1981 by a number of ex-Hewlett-Packard employees, who were interested in building first-rate minicomputers based on RISC designs. In March 1995 Pyramid was bought by Siemens AG and merged into their Siemens Computer Systems US unit. In 1998 this unit was split, with the services side of the operation becoming Wincor Nixdorf. In 1999 Siemens and Fujitsu merged their computer operations to form Fujitsu Siemens Computers, and finally Amdahl was added to ...

Interrupt Technology Corporation
In digital computers, an interrupt (sometimes referred to as a trap) is a request for the processor to ''interrupt'' currently executing code (when permitted), so that the event can be processed in a timely manner. If the request is accepted, the processor will suspend its current activities, save its state, and execute a function called an ''interrupt handler'' (or an ''interrupt service routine'', ISR) to deal with the event. This interruption is often temporary, allowing the software to resume normal activities after the interrupt handler finishes, although the interrupt could instead indicate a fatal error. Interrupts are commonly used by hardware devices to indicate electronic or physical state changes that require time-sensitive attention. Interrupts are also commonly used to implement computer multitasking, especially in real-time computing. Systems that use interrupts in these ways are said to be interrupt-driven. Types Interrupt signals may be issued in response to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
