Write-Solely Memory (Joke) > 자유게시판

Write-solely memory (WOM), the other of read-only memory (ROM), began as a humorous reference to a Memory Wave system that might be written to however not read, as there seemed to be no practical use for a memory circuit from which information could not be retrieved. However, it was eventually acknowledged that write-solely Memory Wave Protocol additionally describes sure functionalities in microprocessor techniques. The concept continues to be often used as a joke or euphemism for a failed memory gadget. 1940s. Considered "an icebreaker", it was intentionally included within the Signetics catalog. Instead of the extra conventional characteristic curves, the 25120 "totally encoded, 9046×N, Random Entry, write-solely-memory" data sheet included meaningless diagrams of "bit capacity vs. Temp.", "Iff vs. Vff", "Variety of pins remaining vs. variety of socket insertions", and "AQL vs. promoting price". 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 form of computer memory into which information will be saved however by no means, ever retrieved, developed below authorities contract in 1975 by Professor Homberg T. Farnsfarfle. Farnsfarfle's authentic prototype, roughly one inch on each side, has to date been used to retailer more than one hundred trillion words of surplus federal data. Farnsfarfle's critics have denounced his mission as a six-million-dollar boondoggle, however his defenders point out that this excess data would have price more than 250 billion dollars to store in typical media. Originally written by Bruce Tognazzini, the write-solely memory definition was not with out its share of inner controversy. The editors insisted the original contained a misplaced modifier whereas Tognazzini was equally adamant that Farnsfarfle was a really small man. The 1995 Laptop Contradictionary guide discusses EWOM, or Erasable Write-Solely Memory (an analogy of EPROM), a memory copyrighted by IBM (Irish Business Machines), which allows the data to be written to and then erased, for memory re-use.

With the explosive development of the amount of digital video data on-line and in non-public use, there emerged a typical joke that video tapes and Memory Wave other analog video media were "write solely memory", as very little of it was still considered.

When the BlackBerry debuted in 1999, carrying one was a hallmark of powerful executives and savvy technophiles. People who bought one both needed or wished constant entry to e-mail, a calendar and a phone. The BlackBerry's producer, Research in Motion (RIM), reported only 25,000 subscribers in that first yr. But since then, its popularity 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. There are phrases for flirting through BlackBerry (blirting), repetitive movement accidents from too much BlackBerry use (BlackBerry thumb) and unwisely utilizing one's BlackBerry whereas intoxicated (drunk-Berrying). While some people credit score the BlackBerry with letting them get out of the office and spend time with mates and family, others accuse them of allowing work to infiltrate each moment of free time. We'll also explore BlackBerry hardware and software program. PDA. This might be time-consuming and inconvenient.

It might also result in exactly the conflicts that having a PDA is supposed to stop. For example, a supervisor might schedule a gathering on the PDA, not knowing that an assistant had just scheduled a meeting for the same time on a networked calendar. A BlackBerry, alternatively, does every little thing a PDA can do, and it syncs itself regularly by way of push technology. First, the software senses that a brand new message has arrived or the info has changed. Then, it compresses, packages and redirects the knowledge to the handheld unit. The server makes use of hypertext switch protocol (HTTP) and transmission control protocol (TCP) to communicate with the handhelds. It also encrypts the information with triple data encryption standard (DES) or advanced encryption customary (AES). The software program determines the capabilities of the BlackBerry and lets folks establish criteria for the knowledge they wish to have delivered. The standards can embody message kind and measurement, particular senders and updates to specific applications or databases.
