Henry Ford VS Von Neumann

April 30th, 2007 No Comments »

Henry Ford had ordered a dynamo for one of his plants. The dynamo didn’t work, and not even the manufacturers could figure out why. A Ford employee told his boss that Von Neumann was “the smartest man in America,” so Ford called Von Neumann and asked him to come out and take a look at the dynamo.

Von Neumann came, looked at the schematics, walked around the dynamo,
then took out a pencil.
He marked a line on the outside casing and said, “If you’ll go in an cut the coil here, the dynamo will work fine.”

They cut the coil, and the dynamo did work fine.

Ford then told Von Neumann to send him a bill for the work. Von Neumann sent Ford a bill for $5,000.
Ford was astounded — $5,000 was a lot in the 1950s — and asked Von Neumann for an itemized account.

Here’s what he submitted:

Drawing a line with the pencil: $ 1
Knowing where to draw the line with the pencil: $4,999

Ford paid the bill.

What Is VIRUS?

April 30th, 2007 No Comments »

In Computers world,a virus is defined as a program or programming code that replicates by being copied or initiating its copying to another program, computer boot sector or document and infect the computer without permission or knowledge of the user.
Transmission of Virus
Viruses can be transmitted as attachments to an e-mail note or in a downloaded file, or be present on a diskette or CD. The immediate source of the e-mail note, downloaded file, or diskette you’ve received is usually unaware that it contains a virus. Some viruses wreak their effect as soon as their code is executed; other viruses lie dormant until circumstances cause their code to be executed by the computer. Some viruses are benign or playful in intent and effect (”Happy Birthday, Ludwig!”) and some can be quite harmful, erasing data or causing your hard disk to require reformatting. A virus that replicates itself by resending itself as an e-mail attachment or as part of a network message is known as a worm.
Classes Of Viruses:
1)File infectors:-Some file infector viruses attach themselves to program files, usually selected ‘.COM’ or ‘.EXE’ files. Some can infect any program for which execution is requested, including .SYS, .OVL, .PRG, and .MNU files. When the program is loaded, the virus is loaded as well. Other file infector viruses arrive as wholly-contained programs or scripts sent as an attachment to an e-mail note.
2)System or boot-record infectors:– These viruses infect executable code found in certain system areas on a disk. They attach to the DOS boot sector on diskettes or the Master Boot Record on hard disks. A typical scenario (familiar to the author) is to receive a diskette from an innocent source that contains a boot disk virus. When your operating system is running, files on the diskette can be read without triggering the boot disk virus. However, if you leave the diskette in the drive, and then turn the computer off or reload the operating system, the computer will look first in your A drive, find the diskette with its boot disk virus, load it, and make it temporarily impossible to use your hard disk.
3)Macro viruses:– These are among the most common viruses, and they tend to do the least damage. Macro viruses infect your Microsoft Word application and typically insert unwanted words or phrases.
First Ever Virus:
The program code called “Elk Cloner”,created in “in the wild”, that is, outside the single computer or lab,is credited with being the first computer virus to appear. Written by Richard Skrenta, in 1982,it attached itself to the Apple DOS 3.3 operating system and spread by floppy disk. This virus was originally a joke, created by the high school student and put onto a game. The game was set to play, but release the virus on the 50th time of starting the game. Only this time, instead of playing the game, it would change to a blank screen that read a poem about the virus named Elk Cloner. The computer would then be infected.
The first PC virus was a boot sector virus called (c)Brain, created in 1986 by two brothers, Basit and Amjad Farooq Alvi, operating out of Lahore, Pakistan. The brothers reportedly created the virus to deter pirated copies of software they had written. However, analysts have claimed that the Ashar virus, a variant of Brain, possibly predated it based on code within the virus.The newest species of the virus family is the cross-site scripting virus. The virus emerged from research and was academically demonstrated in 2005[citation needed]. This virus utilises cross-site scripting vulnerabilities to propagate. Since 2005 there have been multiple instances of the cross-site scripting viruses in the wild, most notable sites affected have been MySpace and Yahoo.
