12th HSC for 2020 and 2021 batch HTML theory .part 1

 What is HTML ?

▪ The HTML is used to create world wide web document .
▪ Using this language user can creat web pages which can view in web browser.
▪ HTML is not a programming language in real sense .
▪ It is set of code that is used to creat document then it can be publish on world wide web .

Advantages of HTML
• No special software is needed .
• Easy to learn and also for implementation .
• Contain a powerful formatting facilities.
• HTML pages updated easily without changing whole document.
• Finding error is easy in HTML.
• It will not cost anything for its use .
• There is no expensive licenses to buy or to upgrade .

Disadvantages of HTML
[ July 2017,06,09,mar-14]
 HTML is not a programming language in real sense.
Any simple calculation can no be done in HTML .
It can not be use to print even dates.
Interactive web pages can not build in HTML.
The web pages can be develop in HTML but can not behave like an application.

What are the tags ?
Tag is a simple unit of markup language .
It is a set of sysmbols defined in HTML they have a specific meaning .
Tags are nothing but instructionthat are written directly into text edition.
In HTML every tag is started with < sign followed by keyboard and always end with > sing.
That symbols together called as angle brakets.
Ex :<html> ,<H1>,<body>.

Example
<I>  is an italic tag the text written using this tag and also end with  </I>  displayed in italic mode

   <I> html </I>.

So html will display like ............->html 

Tag can be nested within each other. Lilke <b><I>hello</I></b>

Free notes of the operating system some imp questions

 1. ALU  2. STACK POINTER 3. PROGRAM COUNTER 4. INSTRUCTION REGISTER AND DECODER ALU ( ARITHMATIC AND LOGIC UNIT ) It is 8 bit unit  In this arithmetic and logical operation are carried out . ALU contain the binary adder to perform addition substracion by 2’s complement method Data is supplied by memory devices and input ouput devices The result is typically stored in the accumulator. STACK POINTER:- Stack poiointer is a 16 bit register which contain the address of top of stack With the help of incrementer and decrementer stack pointer perform their work The stack pointer is incremented when data is push  The stack pointer is decrementd when data is pop. INSTRUCTION REGISTER AND DECODER :- During the instruction fetch, the first 8 bit of instruction is transfer to the 8 bit instruction register The content of instruction register are available to the instruction decoder The output of decoder get by timing signals, ALU & data buffer. PROGRAM COUNTER:- Program coun...

partitioning (operatimg system ).

 WHAT IS PARTITIONING ? Certain operating system use partitioned memory management to allow multiprogramming . • Partitioning means dividing main memory into various sections.  • These section are called as partitions.  • There are two types of partitions: 1) fixed partition .    2) variable partition.   Fixed partition  .  • In this method partitions are fixed at the time of system generation . At this time , system manager has to declear partition time.  • Fixed partition are also called static partition . On declearing fixed partition , the operating system create partition description table.  • It reduces the uses the CPU utiliisation .  • It reduces the degree of multiprogramming. .    variable partition .     In variable partition number of partition and their size are variable  • They are not defined at the time of system generation .  • These partition are created by operating systems...
