What is Blue Screen of Death and what causes it?

Blue screen of death is a colloquial phrase used by computer technicians to describe what is officially known as a Stop error in computers. A blue screen appears on the monitor with text in white when the system experiences a critical error and needs to shut down to protect damage to the memory. The appearance of a blue screen during a process means that the only solution to the error is to restart the computer; therefore the phrase ‘screen of death’ was coined to denote the finality of the situation.

A BSOD appears usually when a hardware or hardware driver is installed, which causes certain drivers to become incompatible. Trying to install softwares or hardware which is incompatible with your computer’s configuration can also cause the error to appear. If a hardware component has a buggy device driver, if there is a real time conflict between hardware or an installed application tries to divide by zero, you are likely to get this error. Sometimes this screen might also appear after a considerable time since installing something new, which means that a normal driver has become outdated now. The best solution to getting rid of the blue screen is to reinstall the hardware or software properly after booting the system in safe mode.

If the computer is unable to read properly from the boot device or some recent change in its configuration has caused a driver to become corrupt, then also a blue screen of death can be displayed. Another method to get rid of the blue screen for good is to make a recovery CD of your computer, and then using it to boot up your system and running the repair tool. If the error has appeared because of some serious error in the machine’s registry, then the safest bet for you to avoid losing data is to get professional help in repairing your computer or call the hardware vendor if you have recently installed a component, before you try to boot your system again.

How to get rid of dust inside Computer?

Computers have become a part of our everyday lives. But over time inside parts get dust accumulated in them. Dust enters through the pores or the net provided for processor fan’s outlet, and other open vents on CPU’s cabinet. So it is important to dust them up regularly to ensure smooth working. Dusting and cleaning a computer should be on daily basis, but it can become difficult to keep up the cleanliness. However overtime dust gets accumulated on the inside parts, which can only be removed by opening the cabinet, however, without the cleaning, the computer can get grimy and deteriorate in performance. Therefore, it is necessary to keep it dusted and clean on a regular basis. Many people hate to clean a computer but now there are solutions which help remove the dust easily.

You will need all of the following to maintain a clean computer:
• Mini air compressors preferred (electricity run)
• Wrist strap that is not static
• A dust mask to protect you from dust entering lungs
• Cleaning rag which is anti-static
• A fiber based brush which is also anti static
• Some cleaning fluid
• Micro mini vacuum cleaner having a plastic nozzle for cleaning the keyboard
• Plastic containers of small size

First read the manual of instructions of your computer. Cut the power to your computer and remove all plugs and wires connected to it. Keep track of what wire fits in which socket so that you do not have a problem later when rejoining it all. Sit down with the computer in an open area which you can clean up later.

Open up the casing for the CPU with a screwdriver. Then, wearing the static wrist band and the mask, use the small vacuum cleaner around the insides of the CPU carefully and remove the dust inside. Then you need to air the CPU by using the small air-pressure compressor/blower. Using the non-static brush carefully, clean all the dust. Use the cleaning fluid after thoroughly checking to see it does not harm the computer. Use a cloth which is anti-static and rub all over the computer to remove grime, dirt and dust from it.

Put together the computer. You should repeat this kind of cleaning every 6 months for best results.

To keep dust away, place the computer on an elevated level. However, never use a hair dryer to clean the computer since it blows hot air and the parts inside of the computer may get damaged.

Who invented the television?

There are many differences of opinions which crop up while deciding who invented the television. This is so because there are a number of inventions and discoveries which led to the development of the television.

Early Origins
The pioneering works of Michael Faraday, Joseph Henry, the invention of pantelegraph in 1862 by Abbe Giovanna Caselli and significant works by scientists such as George Carey, Eugene Goldstein, Sheldon Bidwell, Edison and Bell during the latter 1800s cannot be underestimated.

Paul Gottlieb Nipkow, a German national, invented the ‘Nipkow disc’ which was a rotating disc technology capable of transmitting images through cable, way back in 1884. A few decades later, a Scottish inventor named John Logie Baird, developed technology which used arrays of transparent rods to transmit images which could be delivered to and be seen on TV sets.

TelevisionIn 1924, Baird was successful in televising the first pictures of moving objects and in 1925; he successfully transmitted the image of a human face. The year 1926 was to see another milestone with Baird transmitting the first live moving object.

Role of Philo Farnsworth
However, it is the American inventor Philo Farnsworth who is widely credited with developing the first electronic television. Farnsworth successfully transmitted the image of a dollar sign which was double the resolution which Baird was able to achieve.

Role of Werner Flechsig
The German, Werner Flechsig, created the forerunner of the analog signal TV in 1938 which he patented and unveiled at international fairs in 1939. The world’s first monochrome compatible, electronic, color television was developed by RCA Laboratories during1946-1950. In 1948, the Dumont Company started manufacturing TV sets which soon became the standard for other TV sets.

Who invented the internet?

Life without the internet cannot be imagined today but few among us know who invented it. The fact that the World Wide Web and the internet are different also leads to a lot of confusion and controversy.

Origins
The internet which basically means a network of computers was first discussed by Leonard Kleinrock in 1961. In his paper, he described a process called packet switching where data packets can travel from one place to another by carrying the address information in the data itself.

JCR Licklider described a world wide network called the Galactic network of computers in 1962.

InternetThe first working long distance computer networks were created by Larry G Roberts in 1965 who also designed something called The Advanced Research Projects Agency Network (ARPANET) in 1966, which was the prototype of the modern day Internet.

The Transmission Control Protocol which moves data on the Internet was invented by Vint Cerf and Bob Kahn in the early 1970s and they are often considered to be the real inventors of the Internet.

Later Developments
Further developments during the 1980s gave the Internet many new features which contributed to its final shaping. In the 1980s, Radia Perlman developed the spanning tree algorithm which allows for efficient bridging between different networks, a necessity for the practicality of large scale networks such as the Internet.

By the early 1980s, ARPANET started to resemble the Internet of today in many ways and TCP became the established standard. Robert Cailliau and Tim Berners-Lee are credited for the invention of the World Wide Web, the most popular application of the Internet. Limitations for commercial Internet traffic were removed in 1991and the Internet took off in a big way after 1995.
