System boot process
The boot process begins when you push the power button, which sends power to the bootloader in the cache memory. The bootloader program performs a POST, or Power On Self Test called, and if everything is okay, the Basic Input Output System, or BIOS, is activated and then finds and loads the operating system.

Generation of operating system
Until the 1960's, there were two types of computer systems i.e the scientific and the commercial computers. ... This used integrated circuits and provided a major price and performance advantage over the second generation systems. The third generation operating systems also introduced multiprogramming.
Ecology
Ecology is the scientific study of the interactions between organisms and their environment. An organism's environment is made up of the living, or biotic, and non-living, or abiotic, components of its surroundings. Ecology is separated into various levels of study which include: Organismal ecology.
E-R tables
The database can be represented using the notations, and these notations can be reduced to a collection of tables. In the database, every entity set or relationship set can be represented in tabular form. There are some points for converting the ER diagram to the table: Entity type becomes a table.
Maxflow
This software implements the popular maxflow algorithm described by Boykov and Kolmogorov in the paper: "An Experimental Comparison of Min-Cut/Max-Flow Algorithms for Energy Minimization in Computer Vision", published in IEEE Transactions on Pattern Analysis and Machine Intelligence, September 2004.
Human population
The world's human population is growing at an exponential rate. Humans have increased the world's carrying capacity through migration, agriculture, medical advances, and communication. The age structure of a population allows us to predict population growth.
Python
Python is an interpreted, object-oriented, high-level programming language with dynamic semantics. ... Python's simple, easy to learn syntax emphasizes readability and therefore reduces the cost of program maintenance. Python supports modules and packages, which encourages program modularity and code reuse.
Population and environment
As human populations grow, human demands for resources like water, land, trees, and energy also grow. Unfortunately, the price of all this “growth” is paid for by other endangered plants and animals and an increasingly volatile and dangerous climate.
Circular flow of income
The circular flow of income or circular flow is a model of the economy in which the major exchanges are represented as flows of money, goods and services, etc. between economic agents. The flows of money and goods exchanged in a closed circuit correspond in value, but run in the opposite direction.
E-business categories
eBusiness is an electronic subset of standard business practices. It consists of using both the Internet company Intranet for internal business operations and enterprise communication and collaboration, as well as e-commerce.
Types of leaverages
Leverage is an investment strategy of using borrowed money—specifically, the use of various financial instruments or borrowed capital—to increase the potential return of an investment. Leverage can also refer to the amount of debt a firm uses to finance assets.
Types of ecosystem
Ecosystems are made up of abiotic (non-living, environmental) and biotic components, and these basic components are important to nearly all types of ecosystems. ... Energy is continually input into an ecosystem in the form of light energy, and some energy is lost with each transfer to a higher trophic level.
