Have you ever thought how the data is taken care of in big companies? It might be mind-boggling for you that there are companies who have millions of customers and they are going well in providing customer care to their every customer. Moreover, every query of their customer is answered efficiently and effectively. Similarly there are thousands of documents and files which are in use daily. So how does this all hectic work possible? This is actually done with the help of professional data processing.

If you haven not heard of data processing before then do not worry because I am here to explain to you what data processing is and how it can help you in the success of your business. Keep in mind that no data in business can ever be discarded in business because you may need it in the future and you have to keep it in an order so that you can find it easily when required. This is where data processing comes into action.

Data processing is actually the process of data and converting it to some information. Data process is of different types and each type would give you the output in different time. Although professional data process is imperative and you can not deny this fact yet you must be thinking about some cheap data process if you do not have large scale business because you might not be able to afford expensive data process. Remember that your business can not run without data processing, no matter how small scale business it is!

Many people have the view point that cheap data process is not possible. As a matter of fact, they are quite wrong because cheap data process is, indeed, possible if you really have the right kind of information at the right time. The best source of cheap data process is computer. In case, you have a small business then you don’t not need people to manually engage into data processing as it will cost you a lot as you would have to pay them per month. So you can keep a computer professional who can keep every data of your business in a compact form. This will be a good source of cheap data processing. Moreover, one or two computers would not cost you a lot.

Another source of cheap data processing is digital data processing. In this data process, all the data is stored in the form of compact discs. This is a remarkable source of cheap data process as it will also give you tremendous portability and you would be able to take huge amount of documents from one place to another. Moreover, compact discs are not expensive and you can process your data cheaply.

You might think that you data would not be in orderly format if you are going to have cheap data processing. In fact, this is not true because there are number of soft wares which are designed solely for this purpose so that you can easily convert your data into a systematic order.

You must keep in mind that the data of your business must remain secure and it must not be lost in any way. Moreover, there may be some confidential information which must not be shared with anyone and this is possible only if you have employed techniques of securing you data. So while going for cheap data process, you must not let the security of the data of your customers be at risk because in this way, customers would lose confidence and you will never be able to have large number of customers, which is surely not useful for your business.

Famous Personalities of Computer Science – Part2

John von Neumann (von Neumann’s Architecture)

Von Neumann built a solid framework for quantum mechanics. He also worked in game theory, studied what are now called von Neumann Algebras, and was one of the pioneers of computer science.

The term computer architecture describes the layout of the machine. All computers use the von Neumann model, named after the American who suggested it.

Tim Berners-Lee ( Founder of World Wide WEB (www))
A graduate of Oxford University, England, in 1989, Tim Berners-Lee invented the World Wide Web, an internet-based hypermedia initiative for global information sharing while at CERN, the European Particle Physics Laboratory. He wrote the first web client and server in 1990. His specifications of URIs, HTTP and HTML were refined as Web technology spread. More Here

Kenneth Lane Thompson & Dennis Ritchie ( Unix OS and C language)

In the 1960s, Thompson and Dennis Ritchie worked on the Multics operating system. While writing Multics, Thompson created the Bon programming language. The two left the Multics project when Bell Labs withdrew from it, but they used the experience from the project, and in 1969, Thompson and Ritchie became the principal creators of the Unix operating system. At this time, Thompson decided that Unix needed a system programming language and created B, a precursor to Ritchie’s C. Read More

MALICIOUS UTILITIES

These utilities are designed specifically to inflict damage.However, unlike other malware programs, they do not perform malicious actions immediately as they are run and can be safely stored and run on the user’s computer.Such programs have functions used to create viruses, worms and Trojan programs, arrange network attacks on remote servers, hacking computers or other malicious actions.

There are many types of malware utilities with different functions.

Their types are described in the table below.

POTENTIALY UNWANTED PROGRAMS

Potentially unwanted programs, unlike malware programs, are not intended solely to inflict damage.However they can be used to breach the computer’s security.

Potentially unwanted programs include adware, pornware and other potentially unwanted programs.

ADWARE

Adware programs involve display of advertising information to the user.They display ad banners in other program’s interface and redirect search queries to advertising websites.
Some adware programs collect and redirect to their developer marketing information about the user, for example, which sites he or she visits or which search requests he or she performs (unlike Trojan spies, these programs transfer this information with the user’s permission).

PORNWARE

Usually, users install such programs themselves in order to search for or download pornographic information.

Intruders also can install these programs on the user’s computer in order to display ads of commercial pornographic sites and services to the user without his or her permission.
To be installed, they use vulnerabilities of the operating system or web browser, Trojan downloaders and Trojan droppers. There are three types of pornographic nature distinguished based on their functions.

These types are described in the table below.

OTHER RISKWARE PROGRAMS

Most of these programs are useful programs used by many users. They include IRC clients, dialers, file downloading programs, computer system activity monitors, utilities for working with passwords, FTP, HTTP or Telnet service internet servers.

However, if an intruder obtains access to these programs or install them to the user’s computer, such intruder can use some of their functionality to breach the security. Other riskware programs are classified depending on their functions.

Their types are described in the table below.

TROJANS

Unlike worms and viruses, trojan programs do not create copies of themselves. They sneak into a computer, for example, via e-mail or using a web browser when the user visits an “infected” website. Trojan programs are launched by the user and start performing their malicious actions as they run.

The behavior of different trojan programs in the infected computer may differ. The major functions of Trojans are blocking, modification and erasing of data, disruption of the operation of computers or computer networks. Besides, Trojan programs can receive and send files, run them, display messages, access web pages, download and install programs and restart the infected computer.

Types of trojan programs and their behavior are described in the table below.

Everyday new viruses is being spread over the net and most of this viruses are difficult to neutralize in one’s PC.So, I was thinking to run description summary in some of the characteristics of this malicious programs(viruses) for you to have better understanding.

Viruses are categorize into two, these are the Potentially Unwanted Programs and Malware Programs.I will focus more in the malware programs category since this is that bring most damage to one’s PC.

Potentially Unwanted Programs-are created not intended solely to inflict damage. However they can be used to breach the computer’s security, includes adware, pornware and other potentially unwanted programs.

Malware Programs-are created with the purpose to damage a computer and its user, for example, to steal, block, modify or erase information, disrupt operation of a computer or a computer network.It is further divided into three subcategories: viruses and worms, Trojans programs and malware utilities.

1.Viruses and worms can create copies of themselves which are, in turn, capable of creating their own copies. Some of them run without user’s knowledge or participation, others require actions on the user’s part to be run. These programs perform their malicious actions when run.

2.Trojan programs do not create copies of themselves, unlike worms and viruses. They sneak into a computer, for example, via e-mail or using a web browser when the user visits an “infected” website. To be launched they require user’s actions and start performing their malicious actions as they run.

3.Malware utilities are created specifically to inflict damage. However, unlike other malware programs, they do not perform malicious actions immediately as they are run and can be safely stored and run on the user’s computer. Such programs have functions used to create viruses, worms and Trojan programs, arrange network attacks on remote servers, hacking computers or other malicious actions.

Viruses and Worms Sub-Category

A classic virus infiltrates into the system, it infects a file, activates in it, performs its malicious action and then adds copies of itself into other files.It reproduce only on the local resources of a certain computer, they cannot independently penetrate other computers. They can penetrate other computers only if it adds its copy into a file stored in a shared folder or on a CD or if the user forwards an e-mail messages with at infected attachment.

Code of a classic virus can penetrate various areas of a computer, operating system or application. Based on the environment, there is a distinction between file, boot, script and macro viruses.

Viruses can infect files using various methods. Overwriting viruses write their own code replacing the code of the file they infect and after they destroy the content of such file. The infected file stops working and cannot be disinfected. Parasitic viruses modify files leaving them fully or partially operating. Companion viruses do not modify files but create their duplicates. When such infected file is opened, its duplicate, that is the virus, will be run. There are also link viruses, (OBJ) viruses that infect object modules, viruses that infect compiler libraries (LIB), viruses that infect original text of programs, etc.

Worms – After it penetrates the system, the code of a network worm, similarly to the classic virus code, gets activated and performs its malicious action. The network worm received its name due to its ability to tunnel from one computer to another – without the user’s knowledge – to send copies of itself through various information channels.

The major method of proliferation is the main attribute that differentiates various types of worms. The table below lists types of worms based on the method of their proliferation.
