Programming Languages

We know what C & C++ are. There was one time when C was so efficient that not a single language was there to beat it. It uses structures hence is a structured programming language. Basically there are two types of programming languages:-

1. Structured programming language

2. Object oriented programming language (OOPs).

In C one limitation was found that it could not manage large programs because all the functions used are dependent to each other. Hence it makes it too difficult to understand the program or debug the program.

Object oriented programming languages.

In order to overcome this limitation of C, another programming language called C++ was introduced. At present it is the most powerful language. Most of the operating system uses C++. Windows comprises of 90% C++ and rest is written in java. C++ is an object oriented programming language. But when a program becomes wholly object oriented it becomes very slow. This is why java is much slower than C. One more language called smalltalk was developed. But it could not become much famous because of its slow speed. Basically C++ is not fully OOPs language but object based language because we can write programs in C without using class.

What is an object?

Object in the OOPs is a real world entity. It contains two things that are very much important in it. They are:-

1. Attributes

2. Functions

Attributes are the characteristics of object and functions are the program to access the attributes.

Why OOPs is more preferred than structured?

Human nature is to think about object more as compared to algorithms. As structured languages use algorithms and OOPs uses object , It makes it easy to work with objects.

Protect Your Inbox From Spam Mails

E-mails are one way to send information in a fast and safe manner. We can classify the e-mails into two categories. The first category e-mails are those that are useful mails from our friends, relatives and business related mails. The second category e-mails are useless mails that are sent through virus programs. No one likes to have these unnecessary mails stored in their inbox. These mails are usually referred as junk mails or spam mails. Many people think that it is a tedious process to find and destroy the junk mails. But that is not the case. We can make use of softwares to prevent spam mails from entering our inbox. One such software is Mozilla Thunderbird, which can be downloaded for free in the internet.

How It Works?

• After installing Mozilla Thunderbird properly, go to your inbox using this software.
• Select all junk mails in your inbox and click the Junk button in the menu bar.
• Now all the junk mails will be moved to the junk folder.
• See if any useful mails are there in your Junk folder and if it there move it to the inbox.
• By doing this, useful mails will come to your inbox and junk mails will go to the junk folder automatically.

Preparing The white List

The white list contains the e-mail addresses of those from whom we receive useful mails.

• Click the tools button in the menu bar available in Mozilla Thunderbird.
• Click the ‘Junk Mail Control Option’.
• Select ‘Do not mark messages as junk mail’.
• Click ‘Personal Address Book’ option that appears in the dialog box.
• Click Ok. All the e-mail addresses present in the inbox will get stored in the address book.

Make Use Of The Utilities Softwares

To work with the computer efficiently, we have a number of softwares available in the market. Softwares are available for performing both simple and complex operation. Apart from softwares, Utilities software is the collection of a number of small programs. Utilities softwares can help us to solve the small problems that arise while working in the computer. Some times the internal hard disk may fail or the computer may fail totally or you may have problems with the speed of the computer. At these times, Utilities software comes in handy. Even though many Utilities programs are available, I will mention some of the common facilities here.

1.Trouble Shooting or Diagnostic Programs

Diagnostic programs help to find the problems developed in the computer. You can use trouble shooting programs to solve those problems.

2.Antivirus Programs

This type of utilities program helps the computer in a number of ways. Since virus attack is the main problem these days, you should make the full use of this utility.

3.Uninstall Programs

We generally install a number of softwares to make the work easier. These installed softwares will be stored as a number of programs in the computer. If you delete a software, all the installed files of that particular software will not be removed. So you should use Uninstall options to delete any software from the computer permanently.

4.Backup Programs

At times, some installed softwares in the computer fail suddenly. If you do not have the Software CD, then it will be a difficult task to install that software again. So, if you make a copy of that software in your computer, it will be helpful during those times.

5.File Compression Programs

Some of the files that we use in the computer occupy more space. That is, the size of the file is large. We cannot copy those large files in a floppy disk or a CD. File compression programs help to compress the files, so that the size of the file is reduced considerably.

Windows Utilities

Microsoft’s Windows operating system is used by a number of people worldwide. It is very easy to use and the user friendly interfaces are the key factors that make it more appealing. Under the System Tools option you can see the facilities Backup, Disk Clean up and Disk Defragmenter.

1.Backup

The first utility that comes in this list is Backup. This utility makes a copy of all the softwares and stores it in another location in the computer. When you encounter a problem with any particular software, you can get it from the Backup. You can use it by going to Start->All Programs->Accessories->System Tools->Backup.

2.Disk Clean Up

The next main utility is Disk Clean Up. It helps in finding unwanted files in the computer and deleting them. When using internet, some unnecessary files and photos are loaded into our computer without our knowledge. These files simply waste the space and reduce the computer speed. Disk Clean up will delete all those files and helps the computer to run efficiently.

3.Disk Defragmenter

The files are stored in the computer in a random manner. Due to this, the memory space is wasted. Disk Defragmenter reallocates all the files in a contiguous manner.
