An introduction to how hard drives work

If you want to have some knowledge about hard drives you should start by knowing these three things:

 

  • Hard disks store data in chunks called sectors. If you imagine the surface of the disk divided into rings (like the rings of a tree) and then imagine dividing each ring into slices, with a slice being a sector of a ring. Each sector contains a fixed amount of data, such as 512 bytes.
  • Hard disks have a small arm that can move from one ring to another on their surface. To get to a particular sector, the hard drive then moves the arm to the appropriate ring.

What is an operating system process?

Whenever you start a program, it creates at least one process. In terms of operating system, a process is an instance of a single program, although software can generate more than one process. Processes are generally running in two “spaces”.

Why do we need antivirus solutions?

May 16, 2013 |

The term computer virus appeared in 1983 was defined as a program that can infect other programs by modifying them. Unfortunately, viruses can not only be transmitted as executable programs, but can also be infiltrated in PDF or JPG files, for example.

Unlike viruses, worms are malicious programs (malware) which copies themselves from one system to another without affecting other files. For example, some worms spread via e-mail.

Next, Trojans are viruses that always have unexpected effects, opening a gate for hackers acting on infected systems remotely, by stealing passwords and other confidential information. Such systems that are normally used for accessing an infected computer are known as Denial of Service (often abbreviated as DoS – such an attack overloads the system with information and extra traffic).

The general term for malicious software is malware. Malware is a program, file, or code fragment that makes changes on a system without the user’s consent.
