The Bicycle

The bicycle is a common sight in Kathmandu and other towns. We see many persons riding bicycles. We can see even girls using them. The bicycle is an ordinary means of travelling. It is used mostly by the poor people. It is very popular in poor countries. It is used in villages as well as in towns. It requires a smooth grooundd. It cannot be used in the hilly regions.
The bicycle consists of steel frame on two wheels. The frame has a leaather seat. The rider sits on it and places his feet on the pedals. The pedals are connected with the back wheel by a chain. The rider turns the pedals with his feet, and the wheels roll on. The front wheel is connected to a handle. The rider holds the

High Technology

In a search of New York Times articles, the last occurrence of the phrase "high tech" occurs in a 1950s story advocating "atomic energy" for Europe:"...Eastern Europe, with its dense population and its high technology..." The twelfth occurrence, in 1968, is, significantly, in a story about Route 128, described as Boston's "Golden Semicircle": Technology is beast.
“
It is not clear whether the term comes from the high technologies flourishing in the glass rectangles along the route or from the Midas touch their entrepreneurs have shown in starting new companies.

”By April 1969, Robert Metz was using it in a financial column—Arthur H. Collins of Collins Radio "controls a score of high technology patents in variety of fields." Metz used the term frequently thereafter; a few months later he was using it with a hyphen, saying that a fund "holds computer peripheral... business equipment, and high-technology stocks." Its first occurrence in the abbreviated form "high tech" occurred in a Metz in 1971.
Before 1970, the term "high technology" appeared a total of only 26 times; during the 1970s, 450 times; during the 1980s, over 4000 times. As of 2006, any technology from the year 2000 onward may be considered high tech.

Architecture

In architecture, high-tech design involves the use of the materials associated with high tech industries of the 1980s and 1990s, such as space frames, metal cladding and composite fabrics and materials. High tech buildings often have extensive glazing to show to the outside world the activity going on inside. Generally their overall appearance is light, typically with a combination of dramatic curves and straight lines. In many ways high tech architecture is a reaction against Brutalist architecture, without the features of post-modernism.
The high tech style emerged in the 1980s and remains popular. In the United Kingdom, two of its main proponents are Richard Rogers and Norman Foster.

Economy
Because the high-tech sector of the economy develops or uses the most advanced technology known, it is often seen as having the most potential for future growth. This perception has led to high investment in high-tech sectors of the economy. High-tech startup enterprises receive a large portion of venture capital. However, if, as has happened in the past, investment exceeds actual potential, then investors can lose all or most of their investment. High tech is often viewed as high risk, but offering the opportunity for high profits.
Like Big Science, high technology is an international phenomenon, spanning continents, epitomized by the worldwide communication of the Internet. Thus a multinational corporation might work on a project 24 hours a day, with teams waking and working with the advance of the sun across the globe; such projects might be in software development or in the development of an integrated circuit. The help desks of a multinational corporation might thus employ, successively, teams in Kenya, Brazil, the Philippines, or India, with the only requirement fluency

Economics and Technologycal Development

Looking back into ancient history, economics can be said to have arrived on the scene when the occasional, spontaneous exchange of goods and services began to occur on a less occasional, less spontaneous basis. It probably did not take long for the maker of arrowheads to realize that he could probably do a lot better by concentrating on the making of arrowheads and barter for his other needs. Clearly, regardless of the goods and services bartered, some amount of technology was involved—if no more than in the making of shell and bead jewelry. Even the shaman's potions and sacred objects can be said to have involved some technology. So, from the very beginnings, technology can be said to have spurred the development of more elaborate economies.
In the modern world, superior technologies, resources, geography, and history give rise to robust economies; and in a well-functioning, robust economy, economic excess naturally flows into greater use of technology. Moreover, because technology is such an inseparable part of human society, especially in its economic aspects, funding sources for (new) technological endeavors are virtually illimitable. However, while in the beginning, technological investment involved little more than the time, efforts, and skills of one or a few men, today, such investment may involve the collective labor and skills of many millions.

Technology Tree

The technology tree or tech tree is an abstract hierarchical visual representation of the possible sequences of upgrades a player can take, by means of research. The diagram is tree-shaped in the sense that it branches at certain intervals, allowing the player to choose one sequence or another.Typically, at the beginning of a session of a strategy game, a player may only have a few options for technologies to research. Each technology that a player researches will open up more options, but may or may not, depending on the computer game the player is playing, close off the paths to other options. The tech tree is the representation of all possible paths of research a player can take.
A player who is engaged in research activities is said to be "teching up," "going up the tech tree," or "moving up the tech tree." Analysis of a tech tree can lead players to memorize and use .

Technical Education

`Technical education denotes the knowledge and use of some special skills engineering, agriculture, wearing, cerpentry come under technical education Technicel education teaches us not only theory but also prachce. Technical education teaches us not only theory but also gives us knowledge but it has no practical apphication. One who has received technical example, a pilot can drive an aeroplane, an engineer can build a bridge a carpenter can make furniture.

Techical education helps the progress of a country. Technicians can construct factories, roads, bridge, canals, etc. They can drive trucks, train, ships and aeroplanes. They can help to work mines and produce electricity. They can help to make use of forests. They can help the growth of agriculture and the production of new materials. They can operate telephones and wireless sets. Techniciens can help in every sphere of a nation's productive activities.

Technical education helps a nation to be self-sufficent. If we do not have our own techniciens, we have to bring them from other countries. If other countries do not help us, we cannot develop our industries and agriculture. If we bring technicians from abroad. We have to pay them a lot of money. Nowadays, we are undertaking many development projects in our coutry, but we lack technicians. So many plans and projects have been postponed, or there has been very slow progress.

Technical education helps to solve the problem of unemployment. There is a great demand for technicians in our trends, industries and agriculture.A large number of technicians can be absorbed in various fields. They do not have to remain unemployed like academic graduates and other educated persons. Even if technicians do not find employment, they can stand on their own legs.They can start their own industries of trades. In a developing country like Nepal, there is need of a large number of technicians and there is no fear of their remaining unemployed.

COMMUNICATION

Communication is a process of transferring information from one entity to another. Communication processes are sign-mediated interactions between at least two agents which share a repertoire of signs and semiotic rules. Communication is commonly defined as "the imparting or interchange of thoughts, opinions, or information by speech, writing, or signs". Although there is such a thing as one-way communication, communication can be perceived better as a two-way process in which there is an exchange and progression of thoughts, feelings or ideas (energy) towards a mutually accepted goal or direction.

Communication is a process whereby information is enclosed in a package and is channeled and imparted by a sender to a receiver via some medium. The receiver then decodes the message and gives the sender a feedback. All forms of communication require a sender, a message, and a receiver. Communication requires that all parties have an area of communicative commonality. There are auditory means, such as speech, song, and tone of voice, and there are nonverbal means, such as body language, sign language, paralanguage, touch, eye contact, and writing.

Telephone

The telephone is a telecommunications device that transmits and receives sound, most commonly the human voice. It is one of the most common household appliances in the developed world, and has long been considered indispensable to business, industry and government. The word "telephone" has been adapted to many languages and is widely recognized around the world.

The device operates principally by converting sound waves into electrical signals, and electrical signals into sound waves. Such signals when conveyed through telephone networks — and often converted to electronic and/or optical signals — enable nearly every telephone user to communicate with nearly every other worldwide.
