Write-only memory (WOM), the alternative of read-solely memory (ROM), started as a humorous reference to a memory system that could be written to however not read, as there appeared to be no practical use for a memory circuit from which data could not be retrieved. However, Memory Wave it was finally recognized that write-only memory additionally describes certain functionalities in microprocessor MemoryWave Community programs. The concept remains to be typically used as a joke or euphemism for a failed memory gadget. 1940s. Thought-about "an icebreaker", it was intentionally included in the Signetics catalog. As an alternative of the more standard characteristic curves, the 25120 "totally encoded, 9046×N, Random Access, write-solely-Memory Wave" 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. promoting value". 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 final resting place of all info; see write-solely memory. A type of pc memory into which information can be stored however by no means, ever retrieved, developed under government contract in 1975 by Professor Homberg T. Farnsfarfle. Farnsfarfle's authentic prototype, roughly one inch on each aspect, has thus far been used to retailer more than 100 trillion words of surplus federal info. Farnsfarfle's critics have denounced his mission as a six-million-dollar boondoggle, but his defenders level out that this excess info would have cost more than 250 billion dollars to store in standard media. Initially written by Bruce Tognazzini, the write-only memory definition was not without its share of internal controversy. The editors insisted the original contained a misplaced modifier whereas Tognazzini was equally adamant that Farnsfarfle was a really small man. The 1995 Computer Contradictionary ebook discusses EWOM, or Erasable Write-Only Memory (an analogy of EPROM), a memory copyrighted by IBM (Irish Business Machines), which allows the info to be written to after which erased, for memory re-use.

With the explosive development of the quantity of digital video information on-line and in personal use, there emerged a standard joke that video tapes and different analog video media were "write solely memory", as very little of it was nonetheless considered.

When the BlackBerry debuted in 1999, carrying one was a hallmark of highly effective executives and savvy technophiles. People who purchased one either needed or wished constant entry to e-mail, a calendar and a cellphone. The BlackBerry's producer, Analysis in Movement (RIM), reported only 25,000 subscribers in that first 12 months. But 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. There are words for flirting via BlackBerry (blirting), repetitive motion accidents from an excessive amount of BlackBerry use (BlackBerry thumb) and unwisely utilizing one's BlackBerry while intoxicated (drunk-Berrying). Whereas some people credit score the BlackBerry with letting them get out of the workplace and spend time with pals and family, others accuse them of permitting work to infiltrate every second of free time. We'll also discover BlackBerry hardware and software. PDA. This could possibly be time-consuming and inconvenient.

It could additionally lead to exactly the conflicts that having a PDA is supposed to forestall. For example, a supervisor might schedule a gathering on the PDA, not understanding that an assistant had simply scheduled a meeting for the same time on a networked calendar. A BlackBerry, alternatively, does everything a PDA can do, and it syncs itself regularly by way of push expertise. First, the software senses that a brand new message has arrived or the data has changed. Then, it compresses, packages and redirects the knowledge to the handheld unit. The server uses hypertext switch protocol (HTTP) and transmission management protocol (TCP) to speak with the handhelds. It additionally encrypts the info with triple information encryption standard (DES) or superior encryption normal (AES). The software determines the capabilities of the BlackBerry and lets people establish criteria for the information they need to have delivered. The standards can embrace message kind and dimension, specific senders and updates to specific packages or databases.
