THE WORLD OF IT

Phases of storing and handling data This post is all about the different way of storing the data .data is the most important part of any organization and today the whole IT industry is working for this. most of the times we are spending our time in storing updating and accessing this data. So here the step by step ways of handling data is given. In the beginning of time we are using arrays as a means of storage of data but because of its limitations we switch on to the next concept but it has also some limitations so we move on to the next concept which is queues and then  linked lists.         Arrays Stack         Queues Linked list        Array        Stack Queu Link list Concept: an array is a data structure used to process multiple elements with the same data type when a number of such elements are known. A stack is a      memory in which values are stored and retrieved in “”last in first out” manner by using o

here the program is just to give an overview of  a bank  database using class.object oriented programing is used to handle large database and when we have data in mass then we need to securly handle it . when we are talking about data then the first thing about which we are concerned is it's security and c++ provide this facility so this program is giving an overview that how database can be handled using c++ . #include<iostream.h>                                               //including header file #include<conio.h> class bank                                                                    // defining class { int ac_name,w;                                                     // declairing data members char name[20]; char ac_type[20]; int bal,add; public:                               void insert();                                                           // declairing member function void deposit(); void withdraw(); void display(); }; v

Hello friends I am here with my post which is how to create your own header files but before start I would like to explain what a header file is and why it is used in our program. We all know that a program contain different library functions to perform the given job by user. A header file contains the definition of the functions which is included in that header file. Definition of a function tells the compiler that what operation that function have to perform or in what manner and how many number of argument it accept and how many argument it will return .the type of arguments everything about that function. There are number of header files used in c programming we just have to call as per as our requirement .header files are very useful so let’s make a header file of our own. Follow these steps: First of all create the definition of a function and save it with the extension .h (my_func.h) Example: int sum(int a,int b) { return(a+b); } ·          Now create a progr

In programming we use some variables and to store those variables we used memory space to allocate some space for that variable .when we are using array we can use or allocate memory space dynamically means to allocate contiguous memory space during the program execution .means the way to reserve memory address at run time is called dynamic memory allocation or in short it refers as DMA. There are two functions used to allocate: Malloc():used for allocation of memory space at run time Syntax: int *ptr; Ptr=(int*)malloc(n*sizeof(int)); ·          Here ptr accepts the base address returned by the given statement. ·          Malloc is the function used for allocation of memory space. ·          N stands for number of elements ·          Sizeof return the size of the data type enclosed in the bracket Calloc():  is same as malloc() but there is a minor difference between this will be clear after watching this example: Syntax: int *ptr; Ptr=(int*)malloc(n,2); ·          Here ptr

As an alternative to setting up multiple accounts in OUTLOOK EXPRESS you can use the program MAILALERT to check for e-mail and alert you when it has arrived. Mail Alert is a highly customizable program that can not only tell you when you have mail, but can also beep your pager as well the program work with POP and I-MAP mail system as well as with mail systems such as Microsoft exchange and windows messaging. You can have mail alert check for mail and not only chek or alert you but automatically open the e-mail program and show the message you can also use mail alert as a program itself with which you can compose, reply to ,or delete mail.  Mail alert gets its initial settings from your current e-mail program .when you first install your mail alert ,it will ask you to select from the e-mail program on your computer and then it will use the information from the first account it finds in that program such as its names, mail servers,and connection type and your member name and password

E-commerce and shopping online are here to stay. there are 12 steps which can be follow for shopping online safely because while shopping online we always afraid of being cheated so this post will help readers to get read of their fear. 1.        Start conservatively: If you have never shop online before start purchasing a small ,inexpensive item just to get feel for the process.

There are many individuals who had desire to purchase online something, but expressed concern about using credit card. They chose to fax their credit card information on an internet based merchant instead of transmitting online. Faxing is often used as a acceptable alternative, but let’s talk about how safe it is? When we fax information we don’t know that who is on the receiving end-and that assume the dial number correctly.unlike form based financial transaction that is routed to one specific e-mail address, a faxed document usually winds up in hard copy format languishing in the tray of a distant fax machine. It will remain in that location accessible by anybody with access to the fax machine, until somebody comes along , removes the document and process the information in an appropriate manner- you hope. Faxing credit card information is a risky process at best, yet most people are comfortable with faxing information,so it is not perceived as being particularly insecure.many of

There are tens or thousands of newsgroup on the internet. the groups are divided into categories and subcategories. A single newsgroup’s name generally follows the pattern: Category.subcategory.sub-subcategory For example, the newsgroups alt.animals.dogs is a newsgroup where people who are interested in dogs can gather. Vevn more specifically, alt.animals.dogs. obedience is where people are interested in dog obedience  can gather. There are thousands of categories out there. Some of the widely used categories are listed in table: NEWSGROUP, CATEGORIES,DESCRIPTION,AND NAMES: MAIN CATEGORY                       DESCRIPTION                                                SAMPLE NESGROUP NAMES ALT                                                   Alternative lifestyle and topics                   alt.astrology.metapsyche     Alt.beer                                                                                                                                   

Like all other things computer-ish newsgroup have their own language for describing things. Here’s a quick rundown of the more common buzzwords: Each message in a newsgroup is officially called an article or a post though just about everyone refers to them as message because, in a sense, they are like a normal e-mail message, because in a sense, they are like normal e-mail message. A series of article on same subject is called thread. Many newsgroups are moderated by volunteers who weed out posted message that are irrelevant to the group or that are just plain obnoxious. Most newsgroups however are unmoderated, which means anything goes. Lurking is hanging around a group to see what’s being discussed. But unlike lurking around public parks at night which is generally not good and frowned upon by decent folk, lurking in a newsgroup is ok, particularly if you are new to the group. It gives you a chance to get a feel for the group and a better idea of what’s acceptable when

Newsgroups are really more likely to discussion groups.doing news group are more likely to doing  e-mail. In fact you can use outlook express as your news reader(a program that lets you participate in news-group). however, unlike e-mail where message gets sent to one person,the message send to newsgroup might seen by thousands of people. Anyone of those people can reply to your message,just as an individual can reply to your message you send themand those potential thousands can view their replies. Probably the best, if not the most common, use of news group is getting free answer to burning questions. For example, let’s say that you are thinking buying a new car. You have particular make and model of Toyota in mind .before making a final decisionyou’d like to know where existing owners of that car are satisfied . First you would want to find one or more newsgroups where newsgroups where people discuss Toyotas. Then you can just send an e-mail message to that newsgroup that

One aspect of the interconnectedness of the NET is that you can log in to other machines on the internet directly from from your own computer,no matter where you are.with TELNET you can log onto any computer  or network thousands of public sites where passwords are not required .you would not be able to work on these unix systems without telnet, which turns your windows or macnitosh computer into a remote terminal that is compatible with computers outside of the personal computer universe. Many university and public libraries make their catalog available by telnet,as do countlass other repositories of useful information. After you have started your telnet program, you need to open a internet connection and log in to the site with the steps described here: Type telnet and press enter at the unix prompt. This will put you at a telnet> prompt. then type open host site name and press enter. Logging in with telnet is the same as logging in to any computer system.

With FTP we can send files attached to e-mail ,but this is inefficient  and wastes resources if the files are large. Instead there’s FTP a method of retrieving files from and sending files to others computers on the net. Ideally, FTP will be built into windows and MAC operating systems some day (as it already is for unix) , so that managing files on the internet will be easy as managing files on your own computer. The typical FTP session starts when you run the FTP program and connect to an FTP site . depending on the program and connect to an FTP site. Depending on the program you have, you’ll eitherenter your login information before connecting or you’ll be premoted to do it after you connect. If you’re using a web browser to connect to an anonymous site, the browser.  Connecting with FTP May  prompt you to log in, though most send your e-mail address as the password automatically, these general steps illustrate a typical FTP session: 1.        Start your software o
