Port Scanner is the name for the technique used to identify open ports and services available on a network host. It is a process that…

This article describe about Ping of Death, which is a type of network attack in which an attacker sends a network packet that is larger…

Major objective of this lecture is to present on Convex Lens in Water. Since water has a higher index of refraction than air, a convex lens made…

Prime objective of this lecture is to present on Concave Lenses. A convex lens is a diverging lens. When parallel rays of light pass through a concave lens the refracted rays diverge…

End-of-File is a code placed by a computer after a file’s last byte of data. It is either determined when the reader returns null as…

The aim of this lecture is to present on Convex Lenses. A convex lens is a diverging lens. When parallel rays of light pass through a concave lens the refracted rays diverge…

Buffer Overflow is probably the best known form of software security vulnerability. It occurs when a program or process tries to store more data in…

Lenses are made of transparent materials, like glass or plastic, that typically have an index of refraction greater than that of air. Each of a…

Basic objective of this lecture is to present on Convex Mirrors. Convex mirrors reflect light outwards, therefore they are not used to focus light. A convex mirror has the…

This article talks about Static Program Analysis, which is the art of reasoning about the behavior of computer programs without actually running them. In most…

Only parallel rays close to the principal axis of a spherical mirror will converge at the focal point. Rays farther away will converge at a…

General objective of this lecture is to present on Real Images vs. Virtual Images. Real images are formed by mirrors or lenses when light rays actually converge…
