Electronics used during World War 2?
Electronics played an important role in WW2 and literally thousands of books and articles treat the subject in depth. Briefly stated although the first electronic computer was not made during WW2 it followed less than 16 months after VJ day and was a direct descendent of the hybrid electro-mechanical computers used for code breaking (ie The Bronze Goddess of the Ultra cryptographers) and ballistic work. Other notable feats of electronic wizardry include the Proximity Fuze (Johns Hopkins Applied Physics laboratory Silver Spring MD), Microwave megatron Radar (Britain and MIT) "Huff Duff" beam detection (Britain) Television aided bomb guidance (Germany) Electronic beam navigation and bombing sighting (Germany) radio telemetry guidance (Germany) ASDIC and SONAR (Britain) not to mention all the electronics involved in the Manhattan project (nuclear weapons). These are just a few of thousands of examples of electronics applications in the Second World War.
Can you get files back after you delete them?
its possible if you havent erased or formatted your drive
YES with undelete software. This can be down loaded from MajorGeeks.com or you can purchase software to do this. Find the actual file in the directory, right click on it and select "delete". A confirmation question may appear, click on yes, and it's gone. Actually, it isn't really gone, rather it goes into the "recycle folder" and sits there until it is blasted away by you later on.
It was created by Phonicians. It is also know as the Alphabet.
Delete Activity History Trillian Astra?
For Windows 7 running Trillian Astra:
Go to: C:\Users\[USERNAME]\AppData\Roaming\Trillian\users\[USERNAME]\logs
And erase the folders within. If history logging is on, trillian will simply recreate the folders and new log files.
What was the first computer company to start in a garage?
The Hewlett Packard (HP) partnership was launched in a garage in 1938. The garage was renovated in 2005 and was named as the "Birthplace of Silicon Valley". (See links below)
The use of "MY Computer" is to display your drivers, A, C, D, E, F, etc. This allows you to view what is on "your computer"... basicly. Hope that answered your question.
In how many ways can Jan arrange the letter in her name?
Six. She has three choices for the first letter, two for the second and one for the third.
3x2x1=6
What was the document Martin Luther posted?
Martin Luther is famous for posting his Ninety-Five theses on the door of Door of All Saints' Church in Wittenberg on 31 October 1517. The story of the posting on the door, even though it has settled as one of the pillars of history, has little foundation in truth. Luther was strongly law abiding and it would have been against his character to publish his thoughts and direction in this manner.
Luther never mentioned anything in this direction in his writings, and the only contemporary account of the publishing of the theses is the Latin account by his servant Johannes Agricola, who states that Luther presents "certain theses in the year of 1517 according to the customs of University of Wittenberg as part of a scientific discussion. The presentation of the theses was done in a modest and respectful way, preventing to mock or insult anybody". He makes no mention of nailing the theses to a door, nor does any other source report this. In actuality, Luther is known to have presented a hand-written copy, accompanied with honorable comments to the archbishop Albrecht of Mainz and Magdeburg, responsible for the practice of the indulgence sales, and to the bishop of Brandenburg, Luther's superior.
a very wierd guy, I think his name was....Diego? maybe but anyway, he was a director of the first movie zolo was in....so, sorry Im not much of a heeeeeeeeelllllllpppppp!!!! :)
Could the first mechanical calculator add subtract mulitply and divide?
No, the very first mechanical calculators could only add and subtract. The first mechanical calculators were invented in 1623 by Wilhelm Schickard, followed by the Pascaline, invented in 1645 by Blaise Pascal.
However, calculators that could multiply and divide were in use by the 19th century.
How is parallel processing achieved using pipelining?
A very limited form of parallelism is achieved by using pipelining in that several instructions (up to the limit of the depth of the pipeline) are being processed (each at a different stage of instruction processing) at the same time. An example of this using a 6 stage pipeline is as follows:
- instruction completion (this is the oldest instruction stage)
- data storage to memory
- instruction execution & perform input/output
- data read from memory
- memory address resolution
- instruction fetch from memory (this is the newest instruction stage)
The main advantage of pipelining is that under normal conditions none of the instruction processing hardware becomes idle. The main disadvantage of pipelining is that unscheduled events (e.g. interrupts, branch mispredictions, arithmetic exceptions) cause pipeline content flushes and having to spend time reloading the now empty pipeline to resume correct processing.
Some computers designed with pipelines having an unusually high number of stages had their performance so degraded by that disadvantage that real world benchmarks showed their performance to be only slightly better than the traditional nonpipelined computers, even though their estimated performance was originally much higher. RISC specified that the number of stages in the pipeline should be kept to a minimum to reduce this problem.
Who created the first computer mouse?
It depends how far back you want to go. The trackball, a very similar device, was first created in 1946 by Ralph Benjamin. Douglas Engelbart made the first mouse prototype sometime in the 1960s. However, a German company, Telefunken, demoed the first mouse publicly.
