Science

Science is a systametic enterprise that builds and organise knowledge in the form of testable explanation and predictions about the niverse.In an older and closely relatee refers to a body d meaning of knowledge itself, of the type that can be rationally expalined and reliably applied. A practitioner of science is known as a scientist.

Science classical antiquity, science as a type of knowledge has been closely linked to phhopy.in the ilosearly modern period the words science and philosopy of nature were sometimes used interchanbly. By the 17th century,natural philosopy was considered a seprate branch of philosopy.

In modern usage, science most often refers to way of pursuing knowledge, not only the knowledge itself. It is also ristricted to those branches of study that seek to explain the phenomena of the material universe. In the 17th and 18th centuries scientists incresingly sight to sought to formulate knowledge in terms of laws of nature.

Computer engineering

Computer engineering is a discipline that integrates several fields of electrical engineering and computer science required to develop computer hardware and software. Computer engineers usually have training in electronics engineering, software design, and hardware-software integration instead of only software engineering or electronic engineering. Computer engineers are involved in many hardware and software aspects of computing, from the design of individual microprocessor ,personal computer and super computer, to circuits design. This field of engineering not only focuses on how computer systems themselves work but also how they integrate into the larger picture.
Usual tasks involving computer engineers include writing software and firmware for embaded micros, designing vlsi chips, designing analog sensors, designing mixed signal , and designing operating system. Computer engineers are also suited for robotics research, which relies heavily on using digital systems to control and monitor electrical systems like mortors,communications, and sensors.
In many institutions, computer engineering students are allowed to choose areas of in-depth study in their junior and senior year, because the full breadth of knowledge used in the design and application of computers is beyond the scope of an undergraduate degree. Other institutions may require engineering students to complete one year of General Engineering before declaring computer engineering as their primary focus.

Robatics

A robart is a mechanical or virtual agent, usually an electro, that is guided by c mechanical mechinocomputer. Robots can be semi-autonomous and range from humanoids such as honda and tosy's to industrial roborts, collectively programmed swarm roborts, and even microscopic nano roberts. By mimicking a lifelike appearance or automating movements, a robot may convey a sense of intelligence or thought of its own.
Robotics is the branch of technology that deals with the design, construction, operation, and application of robots, as well as computer systems for their control, sensory feedback, and information processing. These technologies deal with automated machines that can take the place of humans in dangerous environments or manufacturing processes, or resemble humans in appearance, behavior, and/or cognition. Many of today's robots are inspired by nature contributing to the field of bio inspired robotics.
As mechanical techniques developed through the Industrial age, more practical applications were proposed by nikola tesla, who in 1898 designed a radio-controlled boat. Electronics evolved into the driving force of development with the advent of the first electronic autonomous roberts created bywillam gray walter in Bristol, englandin 1948. The first digital and programmable robot was invented by george in 1954 and was named the unimate.

Mecanical engineering

Mechanical engineering is a discipline of engineering that applies the principles of engineering, physics and material science for analysis, design, manufacturing, and maintenance of mechanical systems. It is the branch of engineering that involves the production and usage of heat and mechanical power for the design, production, and operation of mechines and tools. It is one of the oldest and broadest engineering discipline.
The engineering field requires an understanding of core concepts including mechanics,kinametics,thermodynamics, electricity. Mechanical engineers use these core principles along with tools like computer aided emgineering and product lifecycle managment to design and analyze manufacture plants, industrial equipment and machinery, heating and cooling system,transport systems, aircraft,watercraft,robotics,wepons,medical divices, and others.
Mechanical engineering emerged as a field during the industrial revolution in Europe in the 18th century; however, its development can be traced back several thousand years around the world. Mechanical engineering science emerged in the 19th century as a result of developments in the field of physics. The field has continually evolved to incorporate advancements in technology, and mechanical engineers today are pursuing developments in such fields as composites,mechatronics, and nanotechnology.

Economics

Economics is the social science that analyzes the production, distribution, and consumption of goods and services.Economics is the social science that analyzes the production,distribution, and consumption of goods and services. politicsl economy was the earlier name for the subject, but economists in the late 19th century suggested "economics" as a shorter term for "economic science" that also avoided a narrow political-interest connotation and as similar in form to mathematics, "ethics", and so forth.
A focus of the subject is how economic agends behave or interact and how economie work. Consistent with this, a primary textbook distinction is between microeconomics and macroeconomics.microeconomics examines the behavior of basic elements in the economy, including individual agents (such as households and firms or as buyers and sellers) and markets, and their interactions. macroeconomices analyzes the entire economy and issues affecting it, including unemployment, inflation, economic growth, and monetary and fiscal policy.

Family

The family is the group of people living together,sharing together,living under the same roof under common feeling. There are two types of family -Large family and Small family. 

Large family is such family in which family members are many. This family is also called joint family. Actually family members are father,mother,children's,aunt,uncle,grandmother,grandfather, are known as large family.The main advantage of large family is that children's get more cared and there is security in home. There is no loneliness feeling among family members. And the disadvantage is there is food shortage and many more crises of basic needs among family members.All have to depend upon that member who used to work.

And small family means the family with parents, and children.There are no more than 5 members in family. This family is considered as a healthy and loving and happy family. There is better fulfillment of basic needs.But security is less that when mother and father both went for work ,there's none to look after children.so small family is considered as happy and healthy family But less secure.

Internet

The Internet is a global system of interconnected computer network that use the standard internet protocol suite to serve several billion users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents of the world wide web (WWW), the infrastructure to support email, and peer to peer networks.
Most traditional communications media including telephone, music, film, and television are being reshaped or redefined by the Internet, giving birth to new services such as voice over internet protocol and internet protocol television. Newspaper, book and other print publishing are adapting to websites technology, or are reshaped into blogging and web feeds. The Internet has enabled and accelerated new forms of human interactions through instant messaging. Internet forums, and social networking and online shopping has boomed both for major retail outlets and small antisense and traders. business to business and financial services on the Internet affect supply chains across entire industries.
