The Advent Of IT In The 21st Century
Information Technology is widely used in the field of business
and computing. While referring to various types of computer-related work,
people generally use such words, which sometimes lead to their incorrect
meaning.
What does Information Technology actually
means?
Information Technology (IT) means the use of computer
system for Processing, Storing, Retrieving, Securing and Exchanging the information
It also involves use of storage, networking, electronic data and infrastructure
of other physical devices.
In the 1958 article in Harvard Business Review,
Information Technology has been referenced, including following three basic
parts:
1. Computational Data Processing
2. Business Software
3. Decision Support
Information Technology refers to the relation with the
computing technology, such as networking, hardware, software, internet, or
people working with these technologies.
Mostly companies now have their IT departments for managing
their business computers, networks, and other technical areas. IT jobs have
multiple fields like in network administration, computer engineering, web
development, technical support, and many other businesses related work.
In the coming decades, many corporations have created so-called
"IT departments" to manage their business-related computer
technologies. Whatever these departments did, it became the real definition of
Information Technology, which has evolved over time. Today, IT departments have
emerged following responsibilities in these areas:
·
Computer technology support
·
Business Computer Network and
Database Administration
·
Business software deployment
·
Information security
Especially during the 1990's dot com boom, Information
Technology was also associated with aspects of computing outside the owners of
IT departments. This broad definition of IT includes such areas:
1. Application Software development
2. Computer system architecture
3. Project management
Issues and Challenges of Information Technology
SCALABILITY
Since the capabilities of computing systems continue to expand
throughout the world, data overload has become an increasingly important issue
for many IT professionals. To produce useful Business intelligence and
efficient processing of large amounts of data requires mass processing power,
sophisticated software along with human analytical skills.
TRAINING
Teamwork and communication skills have also played vital role
for most businesses to manage the complexity of the IT system. Different IT
professionals have their responsibility for providing the service to those
business users who are not trained in computer networking or other information
technology, yet they are interested in using IT to perform their job
efficiently.
SECURITY
System and network security issues are a major concern for many
business executives because any security event can potentially harm a company's
reputation and cause to spend a large amount of money.
Growth
In Information Technology Jobs
Information Technology, or IT, describes any technology that empowers
or energizes storage, processing, and information flow within an organization.
Any IT related to computers, software, networks, intranets, web sites, servers,
databases, and telecommunication falls below.
The demand for IT professionals is very high. From 2004 to
2014, it has been estimated that 1.3 million jobs will be opened in the IT
sector. This is an increase of 31 percent in the IT job market. And the average
initial salary for computer science, electrical engineering and information
science chief is $ 50,000.
