Javascript;
JavaScript is a scripting language used to enable programmatic access to objects within other applications. It is primarily used in the form of client-side JavaScript for the development of dynamic websites. JavaScript is a dialect of the ECMAScript standard and is characterized as a dynamic, weakly typed, prototype-based language with first-class functions. JavaScript was influenced by many languages and was designed to look like Java, but to be easier for non-programmers to work with.

Applets;
Some applets are able to function as any other normal software application (provided they are hosted by an operating system), but are small in size and perform only a small set of tasks. Examples of applications often classified as applets are all of the Accessories in Microsoft Windows (such as Windows Notepad or Microsoft Paint).

Business-to-Consumer E-Commerce;
Business-to-consumer is an electronic commerce business model in which consumers (individuals) offer products and services to companies and the companies pay them.
This business model is a complete reversal of traditional business model where companies offer goods and services to consumers.

Consumer-to-consumer E-commerce;
Consumer-to-consumer or citizen-to-citizen electronic commerce involves the electronically-facilitated transactions between consumers through some third party. A common example is the online auction, in which a consumer posts an item for sale and other consumers bid to purchase it; the third party generally charges a flat fee or commission. The sites are only intermediaries, just there to match consumers. They do not have to check quality of the products being offered.

Careers in IT

Computer specialists work in computer companies, schools, internet cafes and other institutions that involve a certain networks of computers. They assist clients through the phone, face-to-face or through the email.

Technical Writer;
A technical writer is a professional writer who designs, writes, creates, maintains, and updates technical documentation—including online help, user guides, white papers, design specifications, system manuals, and other documents. Engineers, scientists, and other professionals may also produce technical writing, sometimes handing their work to a professional technical writer for editing and formatting. A technical writer produces technical documentation for technical, business, and consumer audiences.

Software engineer;
Software engineers are like webmasters or specialists except these guys work as a team that design new hardware, software and systems.
Software engineers first analyze users' needs. Then they design, construct, test, and maintain the needed software or systems. In programming, or coding, they tell a computer, line by line, how to function. They also solve any problems that arise. They must possess strong coding skills, but are more likely to develop algorithms and solve problems than write code.

Network Administrator;
A network administrator is a person who is incharge in the overall maintainance and control of a network of computers. He is the highest level of networking staff and does not necessarily get involved directly with the system. A network engineer is employed to fix and maintain the routing and functioning of the computer network.

Programmer;

Computer programmers write, test, and maintain the detailed instructions, called programs, that computers follow to perform their functions. Programmers also conceive, design, and test logical structures for solving problems by computer. With the help of other computer specialists, they figure out which instructions to use to make computers do specific tasks. Many technical innovations in programming advanced computing technologies and sophisticated new languages and programming tools, for example have redefined the role of a programmer and elevated much of the programming work done today.
