What is Computer Worm
A computer worm is a malicious program (computer program or script) with the property of replicating itself once it has been executed. In contrast to the computer virus, the worm spreads without infecting foreign files or boot sectors with its code. Worms often spread via mass email, networks or removable media such as USB sticks. To do this, they usually (but not necessarily need an auxiliary … [Read more...]

MAC Address: Understanding and Examples
The MAC address (Media Access Control Address, also Media Access Code Address) is the number of a device on a data connection. It is a unique identifier assigned to network interfaces for communications at the data link layer of a network segment. It serves as a hardware address for devices, distinguishing them from one another on a local network. Based on this number, data running through the … [Read more...]
Basics of Thermal Imaging Camera
A thermal imaging camera (also known as a thermographic, thermal, or infrared camera, or in the military, a thermal imaging device) is a device similar to a conventional camera, but it receives infrared radiation and, unlike a pyrometer, reproduces the IR radiation as an image of the object. The infrared radiation is in the wavelength range from approx. 0.7 μm to 1000 μm. However, thermal … [Read more...]
How Do POS Terminals Work
A POS terminal (Point of Sale terminal) is an online terminal for cashless payment at a point of sale. It checks a debit card or credit card for blocking and reports the test result to the point of sale. A mobile device is called a "mobile point of sale" (mPOS). When the triumph of ATMs became apparent, banks came up with the idea of replacing three cash handling processes with a single, … [Read more...]
