By Rahul Upase | technorahul

What is a computer virus?

The computer virus is a  program designed with the intention of creating a malfunction and damage to various files and organized data on the PC.

They are called so because they have the ability to reproduce (themselves copied in several places on the disk or diskette).

The first viruses were programs that are interesting print, propaganda or humorous messages on your monitor. They were not destructive, so there was no need to develop any special protection. However, things have quickly changed.

In the late ’80s, computer viruses were pieces of code attached to the program as they were games or word processors. They are designed to run when you start one of these programs. We’re entered in the memory and looking for a suitable ground for expansion.

If they find what they’re looking for, began to their work, which can manifest itself in several ways.

Over time, the virus writers become more creative, because they learned new ” tricks ”. One of the best was the possibility of entering viruses in memory so that it stayed as long as you keep your computer running. This virus is allowed massive replication. Another interesting trick was the possibility of infection by a boot floppy or hard disk.

It is part of the disk that the system reads the after ignition computer.

Today, the spread of the virus on this ground many times less, because programs for virus protection guard boot sectors and the exchange program takes place via CD or the Internet.

History of Technology

By Rahul Upase | technorahul

Development and Origin

Tech image

We all know that the technology has become an important factor in business and life. Its rapid development was reflected in all aspects of life. It is fairly said that technology now directs the development of the whole society.

Despite its positive side, people still realize that we should not blindly hand over the impact of rapid advances in innovation without the right to direct that influence.

The scientists who know the impact of innovation came to the conclusion that survival on this planet needs intelligent decisions. They prevent lightly acceptance of any “new technology”, regardless of its devastating effects on people and the environment. This means that the present time requires us to be “Control technology” and not just its users.

There are two definitions for technologies that are commonly used:

  • Technology is “the application of knowledge to solve human problems” and has a general nature and as such little use.
  • Technology means a group of processes, methods, procedures and equipment used for the production of goods and services. This definition focuses on the technology of the process and not on its products.

Selection of the process that was previously considered in the broadest sense is one of the choices of innovation. In a narrow sense, there are many possible choices of innovation in the context of a specific process. Hence, decisions of the selection process and innovation are closely related and they bring together in practice.

Application of high technology provides a uniform level of quality as opposed to a system with a low-tech solution. Despite all of the above mentioned, it is important to point out the decisions on the selection of innovative work on business strategy by linking it with the processes, equipment, tools and procedures, which means that it works on all parts of the production and overall business.
