When was the first computer network created and by whom?
Contributions to computer networks were made by the following:
CERN in Switzerland
The first computer network was created at CERN the European research center for particle physics. it is in Switzerland.
UCLA in 1969
The previous comment "the first computer network was created at CERN" is not correct. In 1989, CERN added the WWW as a new feature to the already-existing Internet. The Internet itself was created in 1969 at UCLA. There were previous experiments in wide-area networking, e.g., in 1965. For more info, see "history of the internet" on isoc.org.
DARPA
The computer networking revolution began in the early 1960s and has led us to today internet technology. The Internet was first invented by DARPA (Defense Advanced Research Projects Agency) for military purposes, and then expanded to the purpose of communication among scientists. In 1957, the launch of Sputnik had spurred the U.S to create a network for communications links between military and university computers that would not be disrupted by bombs or enemy spies. In order to solve the problem, in 1968 DARPA (Defense Advanced Research Projects Agency) made contracts with BBN (Bolt, Beranek and Newman) to create ARPANET (Advanced Research Projects Agency Network).
Sergei Lebedev in the Ukraine
The first computer network in Ukraine by Sergei Lebedev for the USSR antimissile system. The system was operational in 1960 far before the idea of ARPANET.
SAGE air defence computer network
A network of vacuum tube computers connected by leased telephone lines and the first MODEMs used by the US to protect against bomber attacks. The system was operational in 1958.

What is the startup code that is run when a computer is first powered on?
The bootstrap.
When a computer is first switched on, it runs code held semi-permanently on a dedicated chip, called a Basic Input Output System. BIOS.
This code checks that everything is in order, memory, CPU, hard drives, floppy drives, time and date, mouse and keyboard.
If all checks are OK it will then try and boot up the operating system held on the hard drive.
Parameters in the BIOS can be altered by the user, such as time and date and which drive holds the operating system.
The code is held, even when there is no power.
Is there any people that can solve their own problems?
Most people end up solving their own problems. Sometimes you just have to work through them in your head to figure out the solution.
What computers are currently used?
Well there are a lot of different company computers that are used. You can choose from either Windows or Mac. I myself have a Mac with OSX Leapord. If you are interested, then here is the website, check it out.... I LOVE IT!!!!!!!

What describes the size and shape of the desktop personal computer system unit?
The closest thing that standardizes size and shape is what's known as a "Form Factor". Common form factors are AT, ATX, BTX and ITX. The most common is ATX.
These form factors specify motherboard sizes and general component placement. For example, you usually need an ATX compatible computer case if you wish to fit it with an ATX motherboard.
Which is the hardware of personal computer?
Hardware is the hard stuff you can touch, such as the case, the cards (NIC, Video, Sound, etc) hard drives, etc.
Software is the stuff you can't touch, like the programs that run on the computer like the Operating System (Windows) Office, etc.
John Logie Baird has been called the father of television as it is easy to see that he produced the very first working television system in the world. He did his development work in his own building with his own resources and with his own hands.
The development of CDs and later, DVDs were both commercial developments by a group of companies. The DVD was the result of years' of negotiation between manufacturers, Hollywood production companies and development companies.
Perhaps the closest we can come to finding a father for the DVD is to put forward either Sony or Philips as candidates, being the original companies who began the development of the DVD. It will be hard to select one or the other so we should probably settle for both having shared parenting of the disc format.
