ARP stands for Address Resolution Protocol, a network layer protocol used to convert an IP address into a physical address, such as an Ethernet address. A host wishing to obtain a physical address broadcasts an ARP request onto the TCP/IP network. The host on the network that has the IP address in the request then replies with its physical hardware address.
How to enable Clear history button?
I don't think you can disable it but you could just close the toolbar. As for enabling it, I think it is always there. If you don't have the button and want it I don't know why it's not there. (p.s. I am talking about a google toolbar)
Who invented the adding machine?
In 1642 Blaise Pascal invented the pascaline, the first adding machine using gears, to help his father calculate taxes.
William Seward Burroughs invented a different kind of adding machine in 1885.
Examples of business data processing?
Business data processing is used in a mail merge to retrieve customer's information in sending out advertising. A business accounts dept use data processing to create reports on the financial state of the business, customer credits and debits, personnel wages, etc.
Who invented computers in the ninteenth century?
How has modern computer usage created more jobs or employments?
It has allowed the unemployed to seach fo jobs online
Supercomputers are computers designed to have roughly an order of magnitude or more higher performance than the then current state of the art standard computers. They are used for solving particularly computationally difficult problems that could not be done by other methods in a reasonable time so as to be useful. Some typical uses:
- Airflow models for aircraft, spacecraft, vehicles, wind turbine blades, etc. when using models in windtunnels would be impractical
- Nuclear weapons design and analysis
- Nuclear reactor design and analysis
- Petroleum oil field analysis based on collected acoustic data
- Cryptanalysis
- Long term weather forecasting
- Modeling of the electric transmission grid
- Aquifer models
- Combustion models for jet engines, car engines, rocket engines, etc.
- Firing tables for artillery pieces
- etc.
Of course what is one day's supercomputer is obsolete the next day as performance of standard computers advances. Same as with any other computer.
How many years have computers been around?
This really depends on what you mean by "computer". Probably the earliest design for a programmable computer was by Charles Babbage in 1835. The earliest electronic computers were developed during World War II (around 1943) to decode German messages. The earliest personal computer - designed to be used by one person - was the PDP-8 was first released in 1965.
The first computer which contains most of the components of a modern personal computer was the Xerox Alto, developed in 1973 - it had a windowed, mouse driven, WYSIWYG operating system as well as a laser printer.
When was the first IBM computer released?
IBM announced the IBM 701 on April 29, 1952.
The first production machine sold, serial number 2, was delivered to Los Alamos Scientific Lab on March 31, 1953; it was installed and operational three days later.
What difference does the 5th generation computer have from other generation computers?
The fifth generation of computers is used to describe those created in the early 1980s and lasted until the early 1990s. They were characterized by systems that used logic processing and began the research and implementation of Artificial Intelligence.
How did Charles Babbage got idea to make computer?
Babbage said that drowsing over a book of log tables, (as one does) he got the idea of a machine to do the calculating. But there is not only one person to credit.
In my subconscious (over which I have no responsibility) Napier's bones comes to mind.
There is a good article in wikipedia under invention of computer.
Who made first computer in 1923?
No one. The computer didn't come out until the late 1960s. NOT the 1950s. Even then, in the 1960s the computers were referred to as mainframes, and the PC computer (like what we use today) didn't come out until the early 1980s.
How were mainframe computer tasks accomplished before its invention?
There are many tasks that computers do that had to be done by hand before the existence of computers. Tasks such as file keeping, writing, and record keeping all used to be done by hand at home and at one's job.
Why did Herman hollerith invented the tabulating machine?
To count data in the 1890 census, which could not have been completed on time to meet the requirements of the constitution using traditional hand methods. The tabulator also controlled a sorter so that cards could be separated for appropriate further processing later on other tabulators.
What are the benefits of vacuum tubes?
vacuum tubes help us today with many things. the most important 1 is techology. If we didn't have vacuum tubes we wouldn't have computers. just thik of a life with out computers or t.v. vacuum tubes are also used in radios. so if vacuum tubes hadn't been invented we would not be able to use all the techology we use today.=]
Who is known as the father of computer science?
You may never have heard of him, but it is largely thanks to his genius that you are reading this on your computer.
Alan Turing, a pioneering 20th century mathematician, is widely considered to be the father of modern computer science.Turing was born in London in 1912 into an upper-middle class family and displayed a fascination for science throughout childhood. It was his idea of creating a machine to turn thought processes into numbers which was one of the key turning points in the history of electronic boxes and screens.
A tape machine
While reading maths at King's College, Cambridge, in the 1930s, Turing spent much time reworking earlier scientific principles and developing his most significant mathematical theories. Despite his brilliance, he suffered from a feeling of isolation, and found it difficult to make friends. After graduating, Turing was elected a fellow of Kings, and worked at Princeton in the US, where he began work on what was later to become the first digital computer programme - the "Turing Machine".
His revolutionary idea was for a machine that would read a series of ones and zeros from a tape. These described the steps needed to solve a problem or task. But it was not until nine years later that technology had advanced sufficiently to transfer these ideas into engineering.
Cracking the code
Turing's experiments are credited with helping Britain win World War II by deciphering encrypted German communications, helping the Allies remain one step ahead. The wartime German computer Enigma generated a constantly changing code which was impossible for people to decipher. But Turing's creation of Colossus - one of the first steps toward a digital computer - managed to crack Enigma's codes, giving the Allies the break they desperately needed in fighting Germany.
After WWII, Turing took up long-distance running to relieve the stress and obtained record times in races in the Walton Athletic Club. He went to work for the National Physical Laboratory and continued research into digital computers including developing the Automatic Computing Engine.
Intelligence without life
His research overlapped with philosophy, raising questions about the relationship between computers and nature. He wrote a paper called Intelligent Machinery which was later published in 1969. This was one of the first times the concept of artificial intelligence was raised. Turing believed his invention was like the human brain Turing believed that machines could be created that would mimic the processes of the human brain. He acknowledged the difficulty people would have accepting a machine to rival their own intelligence, a problem that still plagues artificial intelligence today.
He likened new technology devices such as cameras and microphones to parts of the human body and his views often landed him in heated debates with other scientists. Turing believed an intelligent machine could be created by following the blueprints of the human brain. He wrote a paper in 1950 describing what is now known as the Turing Test. The test consisted of a person asking questions via keyboard to both a person and an intelligent machine. He believed that if computer's answers could not be distinguished from those of the person after a reasonable amount of time, the machine was somewhat intelligent. This test has become a standard measure of the artificial intelligence community.
Rebel with a cause
Turing was accustomed to being a nonconformist. At boarding school, he refused to adapt and ignored subjects that did not interest him. He was an atheist, and felt marginalised because of his homosexuality.
Turing's life came to a sad end when he committed suicide by taking potassium cyanide in June 1954.
The official explanation was that it was a "moment of mental imbalance". But his mother said he used to experiment with household chemicals, trying to create new substances and became careless. Others claimed he was embarrassed about his sexuality.
When he died, Turing left the world a permanent legacy. Computers have revolutionised so many aspects of our world that today it is hard to imagine life without them.
What is an example of a compromise?
compromise is kind of like settling an argument Perhaps, Maddie didnt want to buy any poptarts because they were not on sale. But James really wanted to. So they made a compromise........Maddie would buy them but James had to pay half the price. Get it?
What if the computer wasnt invented?
This is sort of a hard question to answer because it's like asking: What if Earth didn't exist? At any rate, life would be very different. Life would be a lot simpler in terms of technology and things would probably be like how life was in the era before computers. Non-computerized cars, very basic hospital care. People would communicate long distances by mail. Life would be very, very, simple to say the least.

Computers weren't discovered, they were invented. In its most basic understanding, computers were invented thousands of years ago by the Chinese, however that is clearly not the case for electronic
What was the second generation computer size?
Transistorized computers varied in size, the smallest being about the size of an office desk, the largest took up most of a room.
The company history of Apple Inc says that a man called Steve Jobs was so impressed with technology shown by Xerox Palo Alto Research Park ( or Xerox PARC as it later became known as) that Steve founded a computer company to let the rest of the world know about this Windows, Icon, Pull Down, (when WIMPS ruled the desktop), Menu system Xerox PARC did have working. Xerox PARC did not protect that innovation so the computer desk was born. Xerox PARC is little more reluctant to talk about what they do now except that the innovation continues.
