Probability: Sample Space: The set of all possible outcomes of an experiment is called the sample space. It is denoted by ‘S’. Each outcome is called element of sample space or simply a sample point. Example:- 1.Flipping/tossing a coin. S={H,T},|S|=2 2.Tossing two coins at a time. S={HH,TT,HT,TH},|S|=4 3.A coin and a dice both are tossed. […]

What is Database? The database is a collection of inter-related data which is used to retrieve, insert and delete the data efficiently. It is also used to organize the data in the form of a table, schema, views, and reports, etc. For example: The college Database organizes the data about the admin, staff, students and faculty […]

ENDOPLASMIC RETICULUM (ER) (i) Introduction and Discovery The E.R. is another important cell organelle that is present in all eukaryotic plant and animal cells. But these are absent in prokaryotic cells. The E.R. was first discovered by Garnier in the year 1897. The structure of E.R. was described by Porter in the year 1953. The […]

UNIX operating system UNIX is a powerful Operating System initially developed by Ken Thompson, Dennis Ritchie at AT&T Bell laboratories in 1970. It is prevalent among scientific, engineering, and academic institutions due to its most appreciative features like multitasking, flexibility, and many more. In UNIX, the file system is a hierarchical structure of files and […]

-:Plant Nutrition & Deficiency Symptoms:- • Plants require 16 essential elements. Carbon, hydrogen and oxygen are derived from atmosphere and soil water. • Remaining 13 essential elements like N ,P ,K ,Ca ,Mg ,S ,Fe ,Zn ,Mn ,Cu ,B ,Mo and Cl etc are supplied either from soil minerals and soil organic matter. • The […]

Geometrical optics   Geometrical optics is branch of optics where light is described by rays. Light rays are conceived as geometrical lines originating from sources, extending though media and being revealed by detectors. The reflection and refraction are the only processes involved in geometrical optics. The geometrical optics fails to explain interference, diffraction and polarisation. […]

    DEVELOPEMENT OF QUANTUM MECHANICS Initially , Newtonian mechanics gave fundamental law , F = ma ; F = force on a particle m = mass of particle a = acceleration of particle It was used to describe motion of a particle . That means we can calculate position , velocity , momentum , […]

ABSTRACT DATA TYPE: An abstract data type, sometimes abbreviated ADT, is a logical description of how we view the data and the operations that are allowed without regard to how they will be implemented. This means that we are concerned only with what data is representing and not with how it will eventually be constructed. […]

DATA STRUCTURE   INTRODUCTION   What is Data Structure? A data structure is a way of storing data in a computer so that it can be used efficiently and it will allow the most efficient algorithm to be used. The choice of the data structure begins from the choice of an abstract data type (ADT). […]
