Write-only Memory (Joke) > 자유게시판

Write-solely Memory Wave (WOM), the alternative of read-solely memory (ROM), began as a humorous reference to a memory device that could be written to but not read, as there seemed to be no sensible use for a memory circuit from which knowledge couldn't be retrieved. Nevertheless, it was finally acknowledged that write-only memory additionally describes certain functionalities in microprocessor systems. The concept continues to be usually used as a joke or euphemism for a failed memory device. 1940s. Considered "an icebreaker", it was deliberately included within the Signetics catalog. Instead of the extra standard characteristic curves, the 25120 "fully encoded, 9046×N, Random Entry, write-only-memory" data sheet included meaningless diagrams of "bit capability vs. Temp.", "Iff vs. Vff", "Number of pins remaining vs. number of socket insertions", and "AQL vs. selling worth". 10 Vcc (double the Vcc of customary TTL logic of the day), and Vdd of 0±2% volt (i.e. floor). It was specified to run between 0 and −70 °C.

The ultimate resting place of all data; see write-only memory. A type of laptop memory into which information will be saved but by no means, ever retrieved, developed below government contract in 1975 by Professor Homberg T. Farnsfarfle. Farnsfarfle's authentic prototype, roughly one inch on every facet, has to date been used to retailer greater than a hundred trillion phrases of surplus federal data. Farnsfarfle's critics have denounced his challenge as a six-million-dollar boondoggle, however his defenders level out that this excess info would have value more than 250 billion dollars to store in standard media. Originally written by Bruce Tognazzini, the write-only memory definition was not with out its share of inside controversy. The editors insisted the unique contained a misplaced modifier whereas Tognazzini was equally adamant that Farnsfarfle was a very small man. The 1995 Pc Contradictionary e-book discusses EWOM, or Erasable Write-Solely Memory (an analogy of EPROM), a memory copyrighted by IBM (Irish Business Machines), which permits the information to be written to after which erased, for memory re-use.

With the explosive progress of the amount of digital video information online and in non-public use, there emerged a typical joke that video tapes and other analog video media had been "write solely memory", as very little of it was still viewed.

When the BlackBerry debuted in 1999, carrying one was a hallmark of highly effective executives and savvy technophiles. Individuals who purchased one both needed or needed constant entry to e-mail, a calendar and a telephone. The BlackBerry's manufacturer, Research in Movement (RIM), reported only 25,000 subscribers in that first 12 months. However since then, its recognition has skyrocketed. In September 2005, RIM reported 3.Sixty five million subscribers, and users describe being addicted to the units. The BlackBerry has even introduced new slang to the English language.

A BlackBerry, however, does every thing a PDA can do, and it syncs itself regularly by means of push technology. First, the software brainwave audio program senses that a brand new message has arrived or the information has modified. Then, it compresses, packages and redirects the information to the handheld unit. The server makes use of hypertext transfer protocol (HTTP) and transmission management protocol (TCP) to speak with the handhelds. It also encrypts the information with triple knowledge encryption commonplace (DES) or advanced encryption standard (AES). The software determines the capabilities of the BlackBerry and lets folks set up standards for the knowledge they wish to have delivered. The criteria can embody message sort and dimension, specific senders and updates to specific programs or databases.
