The developing information technology field there are many different careers, for example, webmaster, computer support specialist, technical writer, software engineer, network administrator, database administrator, systems analyst and programmer.

Firstly, i would like to introduction what is Webmaster. According to my research the definition of Webmaster is a person responsible for maintaining a website(s). The webmasters' duties is to ensuring that the web servers, hardware and software are operating accurately, designing the website, generating and revising web pages, replying to user comment, and examining traffic through the site.

Secondly, Computer support specialist is a job that provide technical assistance to computer system users. their duties is to answer questions or resolve computer problems for clients in person, via telephone or from remote location. In the same time, they may provide assistance concerning the use of computer hardware and software, including printing, installation, word processing, electronic mail, and operating systems.

Thirdly, i would like to cover one of the career in IT which is Technical Writer.
Based on my research, a technical writer is often tasked with writing documentation that explains technical issues in ways that non-technical people can understand. A technical writer might be responsible for writing the how-to manual for a software application. Technical writers are often copy writers and vice-versa.

Fourthly, Software engineer which has generally replaced the term programmer. Software Engineering is intended to mean the processes used to create and maintain software, whether for groups or individuals. This would include subjects like Configuration Management, Project Planning, Project Tracking, Software Quality Assurance, Risk Management, Formal Inspections, etc.

Fifthly, i would like to introduction the career of Network administrator. Network administrator provides technical support and administration of the District Local Area Network (LAN) and Wide Area Network (WAN), assists end users of personal computers with hardware and software problems, and performs other related work as required.For more detail information, you could explore http://careers.stateuniversity.com/pages/218/Network-Administrator.html.

Sixthly, based on the information i get from www.mariosalexandrou.com, a database administrator is similar to a database developer or designer except that a database administrator's key responsibilities is ensuring that a database is available at all to the users and programs that need it. This includes making backups and archiving data. It also includes on-going monitoring to ensure that the database is responding to requests quickly. Sometimes the DBA has some hardware knowledge so that the appropriate servers can be purchased so that the database's performance is not impacted by hardware bottlenecks.

Seventhly, a system analyst is the person who selects and configures computer systems for an organization or business. The system analyst's job is to choose the most efficient computer solutions for a business, while making sure the systems meet all the company's needs. The analyst must understand the general objectives of the business, as well as what each individual user's job requires. Once the system analyst has determined the general and specific needs of the business, he can choose appropriate systems that will help accomplish the goals of the business.

Lastly, programmer is the one who would write the code that would run on the client as well as the code that would run on the server. Because the client often had Microsoft Windows installed, there was often less graphic design needed for the user interface because many of the screen elements were standardized.
