What Is Guided Media? Guided media also referred to as Wired or bounded transmission media, are those that provide a channel from one device to another; they include twisted-pair cable, coaxial cable and fibre-optic cable. A signal traveling along any of these media is directed and contained by the physical limits of the media. Major … Read more

Beam Penetration Method Beam–Penetration Method: It is used with a random scan monitor for displaying pictures. There are two phosphorus layers- Red and Green are coated inside the screen. The color shown depends on how far the electron beam penetrates the phosphorus surface. A powerful electron beam penetrates the CRT, it passes through the red layer and excites … Read more

DIMM and SIMM are two major types of random-access memory standards for personal computers. DIMM is an acronym for “dual in-line memory module,” while SIMM stands for “single in-line memory module.” The naming of each type of RAM refers to the specific way in which the memory is packaged. DIMM and SIMM are manufactured with … Read more

What Is Structured Data? Data that is the easiest to search and organize, because it is usually contained in rows and columns and its elements can be mapped into fixed pre-defined fields, is known as structured data.

What Is Lossy Compression? Lossy compression also referred to as irreversible compression is the class of data encoding methods that uses inexact approximations and partial data discarding to represent the content. In other words, it is a method of data compression in which the size of file is reduced by eliminating data in the file. … Read more
