Introducing HTML

HTML stands for Hypertext Markup Language, and it is the is a language used to develop Websites or Pages. HTML is also Known as markup language.
Like author languages HTML also code.  
Hypertext refers to a text by clicking on that text the user redirect to linked document.
Markup Language HTML is also markup language because its tags tells the web browser How to display the content withhin tags.
What is an html File?
HTML is a format that tells a computer how to display a web page. The documents themselves are
plain text files with special "tags" or codes that a web browser uses to interpret and display
information on your computer screen.
 ƒ  HTML stands for Hyper Text Markup Language
·          ƒ  An HTML file must have an .htm or .html file extension
Why is HTML important?
•   HTML is the foundation of all Web pages.
•   For the same reasons we learn how to perform mathematical operations long-hand before we use a     calculator, learning HTML can be useful.
•   Because HTML pages (Web pages)are really just text-files they can be created with a simple text- 
     editor (Notepad, WordPad, Text Pad, SimpleText, Write). HTML editors may not always be available,warranting the use of a text-editor.
HTM or HTML Extension?
When you save an HTML file, you can use either the .htm or the .html extension. The .htm extension
comes from the past when some of the commonly used software only allowed three letter extensions.
It is perfectly safe to use either.html or .htm, but be consistent. My page.htm and mypage.html are
treated as different files by the browser
Anatomy of an HTML Tag
HTML tags are pre-defined elements written between less than (<) and greater than (>) signs, also
known as angle brackets. There is usually an opening and closing tag. The affected text is contained
within the two tags.

Attributes
Many tags have special attributes that offer a variety of options for the contained text. The attribute is
entered between the element word and the final greater than symbol.
Values
Attributes also have values. These values are the parameters by which the attributes behave (the
value of the attribute defines the attribute). Values should been closed in quotation marks.
The text affected by this particular FONT tag will be displayed using an Arial font-face.
Nested Tags
You may want to modify your page contents with more than one tag. For example, you may want to
add bold formatting to a word within a particular font tag. 
Here order is everything. Whenever you use a closing tag it should corresponding to the last unclosed
opening tag. In other words, first A then B, then /B, and then /A.

Generation of Computers

Generation of Computers   – Computers were developed in different phases known as generations of computer. Depending upon the technologies used the development of electronic computers can be divided into five generations. 1.  First generation The duration lasted from 1946-1959 was based on  vacuum tubes . Because thousands of such bulbs were used, the computers were very large and generate a large amount of heat, causing many problems in temperature regulation.  Magnetic drums   were used for  memory  purpose and instruction and data was given through  punch cards . Computer were operated manually and instruction given in  machine language . E.g.   –   UNIVAC  (Universal automatic computer),  ENIAC  (Electronic Numerical Integrator And Calculator ) ,  Mark I  etc. Main Features  – 1.        Vacuum tube technology used 2.     ...

Input and Output devices

Input device Input device is a device through which data and instruction are entered into computer system. An input devices converts the data and instructions into binary form that computer can understand. This transformation is performed by “Input interface”.   The data entered through input device can be some text, some graphical image or symbol, sound etc, depending on the form of the raw data the various input devices are available. Basic Function Performed by Input unit of a computer system -   1. It accepts the instruction and data from the user. 2. It converts these instruction and data in computer acceptable form. 3. It supplies the converted instruction and data to the computer system for further processing. Some of the commonly input devices used are:- 1. Keyboard 2. Mouse 3. Joy stick 4. Track ball 5. Touch screen 6. Light Pen 7. Digitizer 8. Scanner 9. Speech Recognition Devices 1. Keyboard Keyboard is an input device for enteri...

Computer Memory

Memory :  A memory is just like a human brain. It is used to store data and instructions. Computer memory is the storage space in computer where data is to be processed and instructions required for processing are stored. The memory is divided into large number of small parts. Each part is called cell. Each location or cell has a unique address, which varies from zero to memory size minus one. The computer storage memory is measure in term of Bytes. Eight bits make one Bytes. (Measure units)   Primary Memory/Main Memory Primary memory holds only those data and instructions on which computer is currently working. Has limited capacity and data gets lost when power is switched off. It is also called main memory. It is generally made up of semiconductor device. These memories are not as fast as registers. The data and instructions required to be processed earlier reside in main memory. Characteristic of Main Memory ·         ...
