How did the phrase A bug in the computer get started?
This question has spawned a number of urban myths.
The term 'bug' was first used by Grace Hopper on September 9th, 1945 when a real bug, a moth, short-circuited an early computer on relay number 70 Panel F, of the MARK II Aiken Relay Calculator, in the Harvard University. The operators of the computer said they had "debugged" the computer, and ever since then the terms has not changed. (They actually finished building the computer in 1947, which was the year of the actual event.)
The most widely known is that Captain (later Admiral) Grace Hopper was busy debugging a program that she had written. Finding a moth squashed in her card deck, she quipped "this is the first real computer bug !"
This story gives the lie to the claim that this is where the name came from. If this was the first computer bug, why did she refer to it as the first real one ?
Come to that, why was she debugging her program before the moth was found?
The simple truth is that difficult to find troubles in machinery were already being called bugs by engineers prior to 1900. Tomas Edison may have been the first one to use the term in this sense, writing it in a notebook entry in 1876 regarding problems developing a system of multiplexing signals over a wire for telegraph.

In what format is data stored in a computer?
Data is store momentarily in computers in RAM. Random Access Memory are chips that contain registers that retain their electrical state for as long as its either changed or the power is turn off. Data can also be store permanently in a Hard Drive. HD are nothing more than a magnetic disc that spins around while a writing head magnetises the surface of the disc, creating areas to simbolize ones and zeros; the digital language of computers.
Which fields are required within digital certificates in a public key infrastructure?
Type your answer here... Serial Number and Issuer
Answer Explanation: Digital certificates in a PKI have nine required fields, two of which are the Serial Number and Issuer fields. The Serial Number is an identification number for the certificate. The name of the organization that issued the certificate is required in the Issuer field. Other required fields include the following: Version, Algorithm ID, Validity, Subject, Subject Public Key Info, the digital signature of its issuer, and an algorithm identifier.

A clock is a device to measure the passing of time . Early clocks used water dripping into a container with measurements inscribed on the sides . Later when clockwork was invented , a weight on a string or chain was used to pull a system of gears round , with hands or pointers connected to the relevant gears to indicate against a circular scale(face) . Later still a thin steel strip was wound tightly into a coil to replace the weight on a string , allowing more compact clocks . In order to control the speed the gears turned at , an escapement , an oscillating wheel and arm arrangement............or a pendulum , the swing of which is decided by its length and the mass of weight at the free end...............were used .
Since the discovery of electricity , there were numerous new ways to devise clocks . For battery clocks a transistor oscillator generates a pulse at regular intervals which can be used to step the hands on . For mains power , the public grid has a closely controlled frequency which can been used as a time reference...........
Early digital clocks had the numbers marked on gear driven drums which rotated in the same manner as the hands on the original clocks , or cards or tabs were flipped over to change the numbers . Most digital clocks today use a seven segment display . These became popular with the advent of integrated circuits . They are so-called because with just seven bars in the shape of a figure eight , it is possible to generate any number from zero to nine by turning on or off the correct bars . Special integrated circuits(silicon chips) were produced to match these displays .
Some clocks today use liquid crystal displays , the numerals are made up of tiny tiny dots if you look close , complex electronics drive the display , but they still all need a time reference to control them . The most accurate clocks use an atomic source of which there are several in the world . You can make your computer syncronize itself with one of these over the internet . Radio signals are also transmitted in some countries to allow a good time reference ......
Some clocks are battery operated, while older clocks have gears inside.
