Instructional technology is often referred to as a part of
educational technology. The purpose of instructional
technology, of course, is the promotion of learning. Learning
theory (education) has influenced Instructional design and
Instructional designers (the practitioners of Instructional
Technology). Instructional Technologists promote
communication and interactivity. These two come together
under the general heading of Interaction.
Web design is the skill of designing presentations of content (usually
hypertext or hypermedia) that is delivered to an end-user through the
World Wide Web, by way of a Web browser or other Web-enabled
software like Internet television clients.
Designing Web pages, Web sites, Web applications or multimedia for the
Web may utilize multiple disciplines, such as animation, authoring,
communication design, corporate identity, graphic design, human-
computer interaction, information architecture, interaction design,
marketing, photography, search engine optimization and typography.
A software developer is a person or organization concerned with facets
of the software development process wider than design and coding, a
somewhat broader scope of computer programming or a specialty of
project managing including some aspects of software product
management. A programmer is responsible for writing code, however a
developer’s responsibilities may include:
Computer Engineering is a discipline that combines elements of both Electrical
Engineering and Computer Science. Computer engineers usually have training
Hardware-software integration instead of only software engineering or electrical
Computer engineers are involved in many aspects of computing, from the
design of individual microprocessors, personal computers, and
supercomputers, to circuit 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, designing analog sensors, designing mixed signal
circuit boards, and designing operating systems. Computer engineers are also
suited for robotics research,which relies heavily on using digital systems to
control and monitor electrical systems like motors, communications, and
A computer repair technician is a person who repairs and maintains computers and
servers. The technician's responsibilities may extend to include:
Building or configuring new hardware,
Installing and updating software packages,
Creating and maintaining computer networks.
Computer repair technicians work in a variety of settings, encompassing both the public
and private sectors.
A repair technician might work in a corporate information technology department, a
central service center, or a retail computer sales environment.
A public sector technician might work in the military, national security or law
enforcement communities, health or public safety field, or an educational
institution. Despite the vast variety of work environments, all computer technicians
perform similar physical and investigative processes, including technical support.
Experienced technicians might specialize in fields such as data recovery, system
administration, or information systems.
Organizations need to process a
rapidly growing amount of
information. Data entry and
information processing workers help
ensure the smooth and efficient
handling of information. By keying in
text, entering data into a computer,
operating a variety of office machines,
and performing other clerical duties,
these workers help organizations keep
up with the rapid changes that are
characteristic of today’s “Information
Age.” Data entry and information
processing workers are known by
various other titles, including word
processors, typists, and data entry
keyers, and less commonly, electronic
data processors, keypunch
technicians, and transcribers.
Electrical engineering is a field of engineering that deals with the study and
application of electricity, electronics and electromagnetism. The field covers
a range of subtopics including power, electronics, control systems, signal
processing and telecommunications.
Electronic engineering deals with the study of small-scale electronic systems
including computers and integrated circuits. Alternatively, electrical
engineers are usually concerned with using electricity to transmit energy,
while electronic engineers are concerned with using electricity to transmit
From the Global Positioning System to electric power generation, electrical
engineers have contributed to the development of a wide range of
technologies. They design, develop, test and supervise the deployment of
electrical systems and electronic devices. For example, they may work on the
design of telecommunication systems, the operation of electric power
stations, the lighting and wiring of buildings, the design of household
appliances or the electrical control of industrial machinery.
The webmaster , also called the web architect, the web developer, the site author, the
website administrator, or (informally) the webmeister, is the person responsible for
designing, developing, marketing, or maintaining a website. On community websites,
webmasters are able to change and manipulate any comment that the users make.
Webmasters are practitioners of web communication. Typically, they are generalists with
HTML expertise who manage most or all aspects of Web operations. Webmasters
required to know how to configure web servers such as Apache and serve as the server
Core responsibilities of the webmaster may include:
The regulation and management of access rights of different users of a website
The appearance and setting up website navigation
Content placement can be part of a webmaster's responsibilities, while content
creation is typically not
Are individuals who combine artistic ability with technical proficiency design and create
multimedia products. On a typical project, a team leader will meet with clients to determine what
they hope to accomplish with their interactive multimedia communication—whether it is a Web
site for consumers, an electronic "sales kit" for marketers, or a computer game with the latest in
realistic special effects and graphics. Team leaders then work with designers who help to lay out the
"storyline" of the multimedia presentation using flowcharts; art directors who design the look of
the presentation; and programmers who write the computer code to translate the ideas into a
workable computer program.
In general, multimedia developers must be very people oriented. To succeed in the field, it is
necessary to be able to listen well to clients and coworkers, to communicate ideas and instructions
accurately, and to work well as a team member. Technological skill is just as important as people
skills. Multimedia developers must stay up-to-date with the rapidly changing field of
computer/digital technology, new developments in programming languages, and tools that can
make standard operating procedures obsolete virtually overnight. Finally, multimedia developers
must be adept at project management, including budgeting and scheduling.
Computer programming (often shortened to programming or coding) is the process of
writing, testing, debugging/troubleshooting, and maintaining the source code of computers.
There is an ongoing debate on the extent to which the writing of programs is an art, a craft or
an engineering discipline. Good programming is generally considered to be the measured
application of all three, with the goal of producing an efficient and evolvable software
Computer programmers are those who write computer software. Their jobs usually involve:
A graphic designer (artist) is a professional within the
graphic design and graphic arts industry who assembles
together images, typography or motion graphics to
create a piece of design. A graphic designer creates the
graphics primarily for published, printed or electronic
media, such as brochures and advertising. They are also
sometimes responsible for typesetting, illustration and
web design, or take a teaching position, although these
specialties may be assigned to specialists in various
graphic design occupations. A core responsibility of the
designer's job is to present information in a way that is
both accessible and aesthetic.
