computing

Computing is usually defined as the activity of using and improving computer hardware and software. It is the computer-specific part of information technology. Computer science (or computing science) is the study and the science of the theoretical foundations of information and computation and their implementation and application in computer systems.
Computing Curricula 2005[1] defined computing:
In a general way, we can define computing to mean any goal-oriented activity requiring, benefiting from, or creating computers. Thus, computing includes designing and building hardware and software systems for a wide range of purposes; processing, structuring, and managing various kinds of information; doing scientific studies using computers; making computer systems behave intelligently; creating and using communications and entertainment media; finding and gathering information relevant to any particular purpose, and so on. The list is virtually endless, and the possibilities are vast.
A computer is a machine that manipulates data according to a set of instructions called a computer program. The program has an executable form that the computer can use directly to execute the instructions. The same program in its human-readable source code form, enables a programmer to study and develop the algorithm. Because the instructions can be carried out in different types of computers, a single set of source instructions converts to machine instructions according to the central processing unit type.
The execution process carries out the instructions in a computer program. Instructions express the computations performed by the computer. They trigger sequences of simple actions on the executing machine. Those actions produce effects according to the semantics of the instructions.
Computer programming in general is the process of writing, testing, debugging, and maintaining the source code and documentation of computer programs. This source code is written in a programming language, which is an artificial language, restrictive, demanding, and unforgiving to humans but easily translated by the computer. The purpose of programming is to invoke the desired behaviour (customization) from the machine. The process of writing high quality source code requires knowledge of both the application's domain and the computer science domain. The highest quality software is thus developed by a team of various domain experts, each person a specialist in some area of development. But the term programmer may apply to a range of program quality, from hacker to open source contributor to professional. And a single programmer could do most or all of the computer programming needed to generate the proof of concept to launch a new "killer" application.

History of electric oven

History

The earliest ovens were found in Central Europe around 29,000 BC used as roasting and boiling pits located within a yurt structure. They were used to cook mammoth.[2] In Ukraine from 20,000 BC they used pits with hot coals covered in ashes. The food was wrapped in leaves and set on top, then covered with earth.[3] In camps found in Mezhirich, each mammoth bone house had a hearth used for heating and cooking.[4]
Ovens have been used since prehistoric times by cultures who lived in the Indus Valley and pre-dynastic Egypt.[5][6] Settlements across the Indus Valley had an oven within each mud-brick house by 3200 BC.[5][7] As for the use of the oven in each respective culture, people in the Indus Valley used them as the hardened mud ovens were found in almost every household.[5] The obvious explanation for the popular use of the oven in the homes would most likely involve its use for cooking food. However, baked brick sewers were also found at the Indus Valley civilization, which shows that they used the oven for masonry as well.[5] Other ancient cultures that had use for the oven were pre-dynastic civilizations in Egypt. An early form of blacktopware was produced there which required a kiln. This is another hint showing how ovens were used from about 5000-4000 BC.[6]


Ancient Greek portable oven, 17th century BCE
Culinary historians credit the Greeks for developing bread baking into an art. Front-loaded bread ovens were developed in ancient Greece. The Greeks created a wide variety of doughs, loaf shapes and styles of serving bread with other foods. Baking developed as a trade and profession as bread increasingly was prepared outside of the family home by specially trained workers to be sold to the public. This is one of the oldest forms of professional food processing.
