There is no HTML tag for a background as such. You put in backgrounds by using the attributes of certain tags, depending what you want to put a background on and how you want to display the background. You can also use styles to do it. You can have a colour or an image as a background. The bgcolor attribute is used in a lot of different tags to put background colours on things. So if you wanted the background colour of your page to be red, then you would have the Body tag with the bgcolor attribute like this:

If you wanted an image as the background to your page, you'd have:

Using styles you can do more complicated things with backgrounds. For example, you can use a style to put a background on a paragraph in different ways:

This paragraph will have your image as a background repeating horizontally.

Your paragraph text goes here

This paragraph will have your image as a background displaying only once.

Your paragraph text goes here

Those are just 2 ways, but there are lots more, and they can be applied not just to paragraphs but to other structures like the body or a table or whatever you want.

A 'voltage transformer', together with a 'current transformer', belong to a class of transformers called 'instrument transformers', whose purpose is to enable high voltages and currents to be safely measured by reducing their values to lower levels, while electrically-isolating these high voltages/currents from the measuring instruments. These transformers are also used to provide input to protective relays.

A 'power transformer' is a transformer used in the electricity transmission and primary distribution systems, whose function is to either step up generated voltages (11 - 25 kV in the UK) to transmission levels (400 kV in the UK), or to step down these high voltages at 'load centres', such as towns and cities.

Originally the term referred to people who used a razor blade and/or fingernail clippers to "hack" or roughly cut parts in electronics such as the traces on circuit boards, legs of diodes etc. Police scanners were "hacked" in order to add more memory, remove CPU processors , speed up scanning by "hacking" the crystal oscillator and replacing with faster ones. Thes methods are directly related to why computers now have more RAM, and are faster. Some of the old (and I do mean old) "hackers" devised a system in the 1960s to simultaneously send voice and data over a phone line using frequency phase shifting and filtering. A similar process used later by DSL.

"Hacking" and "Modding" evolved into things such as examining the programming of a thing. Beginning with noticing things such that by pressing certain keys or combinations of keys in certain secquences on a device could produce certain results. Following the era of IBM's "Big Blue" chess tournament, AT&T introduced the "unbeatable Tic Tac Toe Computer, and exhibited it. I, I mean a "hacker" back then, was able to beat the computer with a sequence of key presses in order to "cheat" the computer out of a move. On many Shortwave radios, Police Scanners, even cell phones etc, certain key presses are used in the programming, and could be used to alter that programming.

The keys on a keyboard of a device are a "Matrix" Keyboards use a matrix with the rows and columns made up of wires. Each key acts like a switch. When a key is pressed, a column wire makes contact with a row wire and completes a circuit. The keyboard controller detects this closed circuit and registers it as a key press to the software.

I'm going to try to keep this understandable to readers ...

Software can emulate or act like hardware.

Example: a hardware modem versus a DSP/Digital Signal Processor modem, where a chip is programmed to act like the hardware....

So, later, the focus turned even more from "hacking" the actual electronics and hardware to software "hacking" through PROGRAMMING.

A "black hat" hacker is often referred to as a microcomputer user who attempts to gain unauthorized access to proprietary computer systems. Although that could be a "cracker" ... a person cracking passwords etc.

Most often people who call themselves "hackers" are called "wannabes" by the old-timers, and nowadays are often adolescents using a program they didn't write, by clicking a button they didn't create, to do what don't understand, in an attempt to disrupt something they don't know how to fix.

"White Hat" hackers are the "good guys" like ... Like the old-timers who vastly improved what computers are capable of doing, and the ones currently trying to improve security by locating and preventing weaknesses.

This Answer is dedicated to the memory of Bill Cheek, author, The Scanner Modification Handbook series, and his BBS and Fidonet terminal (prior to "The Internet") Good man, Good freind to many... May he R.I.P.

Static Websites

Static means "constant--never changing". A static website contains Web pages with fixed content. Each page is coded in HTML and displays the same information to every visitor.

Dynamic Websites

dynamic is "changing". You can make dynamic changes to a database without having to shutdown the instance and restart for the changes to take effect. However, if you do not update the control file, when you shutdown and startup, the dynamic change is gone--it wasn't permanent.

• A site whose construction is controlled by an application server processed by server side scripts.

Hope this helped you.

The first internet like network was probably the ARPANET.

In August 1962 computer scientist J. C. R. Licklider, sent out a memo, discussing the idea of an "Intergalactic Computer Network". The ideas in this memo are still used in todays internet. J. C. R. Licklider went on to work with the Advanced Research Projects Agency (ARPA), a division of the US Department of Defense. He helped with the ideas for what became the ARPA Network or ARPANET. The ARPANET's purpose was to link computer science departments at various universities, to improve the deliver of computing results. The contract for it's construction was given to BBN Technologies on 7 April 1969. ARAPANET's first version was completed within 9 months.

Tim Berners-Lee is often credited for creating the internet. In fact he and his team only created a mark-up language called Hyper-Text Mark-up Language or HTML and the protocol for it's transfer known as Hyper-Text Transfer Protocol or HTTP. HTML was simply a way of creating text documents that can link to other documents. This was called a hyper-link. Other tags were added to HTML through it's development to allow for images, input fields, raster plugins, applets and much more to allow more of the functionality we have in today's websites.

In 1980 Tim Berners-Lee, a physicist at CERN proposed and built a prototype of a system for sharing documents called ENQUIRE. In 1989, Berners-Lee wrote a memorandum proposing an Internet-based hypertext system. He finished a writing a HTML browser in 1990. In November 24, 1995 the first official HTML protocol was published.

So the answer is the ideas for the physical network began in 1962 and were realised in 1969. The ideas for today's de-facto internet document HTML began in 1980 and were made official in 1995.
