Soft carriage Return

A soft break or soft return is a carriage return automatically inserted by the software program usually because of a word wrap. Soft returns allow you to continue typing without having to press the return key manually at the end of each line. The picture shows an example of soft returns with formatting marks enabled. The soft returns look like an arrow that goes down and then points to the left, much like the arrow seen on the enter key.


In the picture above blue line indicate hard carriage return and red soft carriage return.

Narrowband ISDN

The first generation of ISDN is called as a narrowband ISDN and it is based on the use of 64 kbps channel as the basic unit of switching and has a circuit switching orientation. The main device in the narrowband ISDN is the frame relay. The second generation of ISDN is referred to as the broadband ISDN (B-ISDN).

Trunk in networking

Trunk


Trunk (Branches between exchanges) in networking is links which enables to connect many clients from a network through sharing a medium or wire frequency we can take example of tree for better understand of trunk.
Tree has a root and many branches whose fulfill their requirement from root.

A trunk is a single transmission channel between two points, each point being either the switching center or the node.

Telephone Local Loop

What is a 'Local Loop'?

The Local Loop in a telephone network (sometimes referred to as the "last mile" of the network) is
the bit that connects your home to your local telephone exchange. It refers literally to the copper
cables that run from your home to the telephone exchange.

Dynamic Array in PHP

     The array is a collection of similar data types which occupies continuous location in memory. There are two types of array static and dynamic. In dynamic array size can be decreased and increase as requirement which best uses of memory utilization on the other hand static array is fixed in nature you cannot increase and decrease array capacity when require so it’s not popular in PHP. We deal with mostly dynamic array in PHP.

Dynamic Array example code :

<?php

$ar=array("Red","Green","Blue");
for($i=0;$i<count($ar);$i++)
{
echo  "<br>" . ($i+1) . "'st element value " . $ar[$i];
}
?>

Example 2:

$ar[]="";
for ($i = 0; $i <$10; $i++)
{
array_push($ar,$i);
}

for($i=0;$i<count($ar);$i++)
echo "<h2>" . $ar[$i] . "</h2>";

Thrashing

     If the number of frames allocated to a low-priority process falls below the minimum number required by the computer architecture, we must suspend that process's execution. We should then page out its remaining pages, freeing all its allocated frames. This provision introduces a swap-in, swap-out level of intermediate CPU scheduling.

     In fact, look at any process that does not have "enough" frames. If the process does not have the number of frames it needs to support pages in active use, it will quickly page-fault. At this point, it must replace some page. However, since all its pages are in active use, it must replace a page that will be needed again right away. Consequently, it quickly faults again, and again, and again, replacing pages that it must bring back in immediately.

     This high paging activity is called thrashing.A process is thrashing if it is spending more time paging than executing.

Reason of Thrashing

     Thrashing results in severe performance problems. Consider the following scenario, which is based on the actual behavior of early paging systems.

SHA1 PHP encryption function

SHA1 accept a string as a key and return hash string which is encrypted. For decryption key is required, which is used in the encryption.

Syntax

string sha1 ( string $str [, bool $raw_output = false ] )

If the optional raw_output is set to TRUE, then the sha1 digest is instead returned in raw binary format with a length of 20, otherwise the returned value is a 40-character hexadecimal number.

Preemption in OS

In computing, preemption is the act of temporarily interrupting a task being carried out by a computer system, without requiring its cooperation, and with the intention of resuming the task at a later time. Such a change is known as a context switch. It is normally carried out by a privileged task or part of the system known as a preemptive scheduler, which has the power to preempt, or interrupt, and later resume, other tasks in the system.

PHP Variable Scope

Local Variable

     A local variable is accessible only the block where it has defined. When a code block over then the entire local variable inside of block automatically released by the compiler.
<?php
           
            function fun1()
            {                      
                        $a=10;
                        echo $a;
            }
            function fun2()
            {
                        echo $a+10;
                        // Error : Undefined variable: a because it has not defined in fun2 and a is local variable for  fun1
            }          
?>
<?php
            //fun1();
            fun2();
?>

Global Variable

     The scope of a PHP variable depends on where it has defined I.e. when a variable is declared in top side of the PHP code block, then it becomes global variable for all PHP code block but not inside of a function.

HTML Tutorial

HTML-Banner


What Is HTML?

HTML is a markup language, not a programming language. In fact, the term HTML is an acronym that stands for Hypertext Markup Language. You can apply this markup language to your pages to display text, images, sound and movie files, and almost any other type of electronic information. You use the language to format documents and link them together, regardless of the type of computer with which the file was originally created.
HTML is written as plain text that any Web browser or word processing software can read. The software does this by identifying specific elements of a document (such as heading, body, and footer), and then defining the way those elements should behave. These elements, called tags, are created by the World Wide Web Consortium (W3C).
simple HTML page
<html>
<head>
<title>My Second Web Page</title>
</head>
<body>
Place Your Code Here
</body>
</html>

Paragraphs


In HTML, a paragraph is created whenever you insert text between the <p> tags
<p>This is my first XHTML page.</p>

Headings
HTML enables you to add six different heading tags to your pages by using the tags <h1><h6>. These tags are very simple to use.

<h1>This is Heading 1</h1>

Class

     In object oriented programming basic working unit start with a class. Class is a template which comprises all the aspect of an object which is a instance of a class.

     In OOP we first create a class to solve any problem. A Class is divide into two parts first is Data section other is function or method section. In data section we get data member which are needed to solve a problem and function section we implement function section functions are defined which handle data.

Deductive logic

Deductive logic reasoning, a conclusion makes on the behalf of some intact fact which show conclusion is true.

Example

  • All man is mortal
  • Rakesh is a man
  • So rakesh is mortal

Deductive logic some time contra of inductive logic because it has strong fact which to mostly conclusion is true. Deductive logic tends to specific conclusion.

Inductive logic

In inductive logic reasoning a conclusion makes on the behalf of some fact like deductive but it is not always necessary that conclusion will be true.

Example

  • Some parents are addicted to alcohol
  • Then it is necessary to their children will also be addicted to alcohol

Is it always happened ? answer is no, not at all. So fact is strong but not showing conclusion will always be true it may be false. Inductive logic make fact specific to general

Data Flow Diagram (DFD)

Overview

Data flow diagram (DFD) represents the flows of data between different processes in a business. It is a graphical technique that depicts information flow and the transforms that are applied as data move form input to output. It provides a simple, intuitive method for describing business processes without focusing on the details of computer systems. DFDs are attractive technique because they provide what users do rather than what computers do.

Select cells, ranges, rows, or columns on a worksheet

On a worksheet, you can select cells, ranges, rows, or columns — for example, to format the data in the selection, or to insert other cells, rows, or columns. You can also select all or part of the cell contents and turn on Editing mode so that you can modify the data.

You can select cells and ranges in a Microsoft Excel table just as you would select them in a worksheet, but selecting table rows and columns is different from selecting worksheet rows and columns.

Information and communications technology

Information and communications technology (ICT) is often used as an extended synonym for information technology (IT), but is a more specific term that stresses the role of unified communications and the integration of telecommunications (telephone lines and wireless signals), computers as well as necessary enterprise software, middleware, storage, and audio-visual systems, which enable users to access, store, transmit, and manipulate information.

The term ICT is also used to refer to the convergence of audio-visual and telephone networks with computer networks through a single cabling or link system. There are large economic incentives (huge cost savings due to elimination of the telephone network) to merge the telephone network with the computer network system using a single unified system of cabling, signal distribution and management.

CPU central processing unit

A central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions. The term has been used in the computer industry at least since the early 1960s. Traditionally, the term "CPU" refers to a processor, more specifically to its processing unit and control unit (CU), distinguishing these core elements of a computer from external components such as main memory and I/O circuitry.

Java Script Tutorial



Loop

A loop describes the process of a software program or script repeats the same instructions or processes the same information over and over until receiving the order to stop. If not handled properly a loop can cause the computer to become slower as it becomes overwhelmed with having to repeat the same steps over and over causing it to get stuck in an endless loop.

Classification of Computers

Computers differ based on their data processing abilities. They are classified according to purpose, data handling and functionality.

According to purpose, computers are either general purpose or specific purpose. General purpose computers are designed to perform a range of tasks.

They have the ability to store numerous programs, but lack in speed and efficiency. Specific purpose computers are designed to handle a specific problem or to perform a specific task. A set of instructions is built into the machine.

According to data handling, computers are analog, digital or hybrid. Analog computers work on the principle of measuring, in which the measurements obtained are translated into data. Modern analog computers usually employ electrical parameters, such as voltages, resistances or currents, to represent the quantities being manipulated. Such computers do not deal directly with the numbers. They measure continuous physical magnitudes. Digital computers are those that operate with information, numerical or otherwise, represented in a digital form. Such computers process data into a digital value (in 0s and 1s). They give the results with more accuracy and at a faster rate. Hybrid computers incorporate the measuring feature of an analog computer and counting feature of a digital computer. For computational purposes, these computers use analog components and for storage, digital memories are used.


According to functionality, computers are classified as :
