During the Hacking 1990s, the term “hacker” originally denoted a skilled programmer proficient in machine code and computer operating systems. In particular, these individuals could always hack on an unsatisfactory system to solve problems and engage in a little software company espionage by interpreting a competitor’s code.

Hacking is identifying weakness in computer systems or networks to exploit its weaknesses to gain access. Example of Hacking: Using password cracking algorithm to gain access to a system
Computers have become mandatory to run a successful businesses. It is not enough to have isolated computers systems; they need to be networked to facilitate communication with external businesses. This exposes them to the outside world and hacking.

There now are more than 100,000 known viruses with more appearing virtually daily. The myriad of hackers and their nefarious deeds can affect any computer owner whether an occasional home user, e-mailer, student, blogger, or a network administrator on site or on the internet. No matter your level of computer use, you must protect your computer, business, or even your identity. The best way to know how to protect your computer is to understand the hacker’s tools and recognize their damage.
Viruses, Exploits, Worms, and More
The term computer “virus” originated to describe machine code command inserted into a computer’s memory that, on execution, copies itself into other programs and files on the computer. Depending on the hacker’s intent, the design of a virus can merely be an inconvenience or have very serious consequences up to a potential catastrophe.
Generally, a virus is a piece of software, a series of data, or a command sequence that exploits a bug, glitch, or vulnerability. Each example is appropriately termed an “exploit.” An exploit causes unintended or unanticipated behavior to occur in a computer’s operating system or applications while propagating itself within the computer.
Protect Your Computer: Avoid Computer Holes/Vulnerabilities
Install only trusted software and delete unknown emails. If you have any doubt about a piece of software’s function, do not install it. If you receive e-mails from random people’s names, resist your curiosity and do not open it, just delete it.
Under no conditions download or open attachments from anyone that you do not know and even then be cautious. Banks and most companies that create online personal accounts will not send you attachments. If they do, it is probably best to go to the company site and request the download or at least see if it is legitimate. Avoid adult web sites, a hacker’s paradise.
Whether in your e-mail or online, do not click on ads. If the ad is of interest, find the site. Be careful with what you physically put into your computer. This is especially true for shared R/W CDs, USB hard disks, or flash drives. This is an easy path for a virus to follow from computer to computer.
