Information Technology (IT)

 Information technology 

When it comes to information technology (IT), people usually associate it with the guys and gals who fix computers for them. It is not quite right to view information technology in that way, but it drastically underestimates its importance.

The use of computers for storing and retrieving data and information is known as information technology (IT). As opposed to personal or entertainment technologies, ITs are typically used within business operations. ICT (information and communication technology) is a subset of IT. As a general rule, an information technology system consists of either an information system, a communications system, or, more specifically, a computing system that is controlled by a small group of specialists.

IT stands for information technology, but it also encompasses television, smartphones, and other means of information distribution. Any technology that has to do with computing is an IT.

Why information technology is important? 

The information technology field plays an important role in all types of businesses, whether small, medium, or large (international). Communication in companies is implemented with the use of information technology. Organisations, both internal and external, rely heavily on networks (intranet and internet) and email to communicate.

It is becoming more and more important for businesses to implement sophisticated solutions that are intuitive. Edward Kiledjian, the chief information security officer at a technology blog and chief information security officer at a product company, highlights that IT can give a company the edge it needs to outpace, out, and out-deliver its competition. 

  • Overwhelming data is a problem faced by businesses. The process requires powerful computers, sophisticated software, and sophisticated analytical skills.

  • The use of mobile and wireless devices: More companies are offering remote work that requires smartphones, tablets, and laptops with wireless hotspots and roaming capabilities.

  • Often, businesses rely on cloud storage services to handle their data storage needs. Many businesses use cloud services to store their data. In most cases, third parties are responsible for providing these services.

  • Hosting video conferences over the internet has become more popular, which means more network bandwidth is needed to support these solutions.

Five Components of IT 

 Five components are described as being part of an information system.

  • Computer hardware 

Technology that works with information is called information technology. There are many types of hardware on the market, such as smartphones that fit in a pocket or supercomputers that fill a building. In addition to computers, hardware consists of peripheral devices including keyboards, external disk drives, and routers. 

  • Computer software 

The software must communicate with the hardware so it knows what it should do. A piece of software may be divided into two types: application software and system software. Windows or iOS, for example, are the operating systems which control the hardware. There are specific applications for specific purposes, such as spreadsheets, documents, and Web pages.

  • Information and communications technology

Networking is the process of connecting hardware together. It's possible to connect wirelessly or through wired connections, like Ethernet or fibre optics. LANs, also known as local area networks (LAN), allow computers to communicate in a shared area, such as a school or an office. 

  • Data warehouses and databases

Material for working with the other components resides in this component. Basically, a database is a collection of data from which you can retrieve it with the aid of a query. In a data warehouse, an organisation can store all of its data in whatever form they need.

  • HR & procedures

Last, and possibly most importantly, is the human element of information systems: the people who use the system and the processes they follow so that the knowledge contained in the huge databases and data warehouses is turned into learning that can guide future actions based on what has happened in the past.

Hardware vs software 

The hardware of a computer system consists of all its physical parts. A computer's motherboard, central processor, hard drive, and other internal parts make up this kind of hardware. Also known as peripheral hardware, this comprises peripheral devices like a keyboard, mouse, and printer that can be connected to a computer. 

Nevertheless, it is important to keep in mind that some tablets and smaller laptops also include keyboards and mice. You can physically touch and manipulate hardware if it has to do with computers and their networks.

You cannot physically change software, as opposed to hardware. Essentially, software is everything, like an operating system, an application, or even video editing software, stored electronically.

Perspectives on Information Technology

Academic perspective 

Typical academic definitions of Information Technology include "undergraduate programs that prepare students to handle computer technology needs in business, government, healthcare, schools, and other organisations.".

IT specialists choose appropriate hardware and software products for an organisation, integrate them into the organisation's needs and infrastructure, and then install, customise, and maintain the applications for the organisation's computer users."

Commercial perspective 

It is not uncommon to refer to the market for information and communication technology companies collectively as the "tech sector".  It is important not to confuse these titles with the term "tech companies", which is usually a term for large, for-profit firms that market consumer technology and software.

Today, many businesses have IT departments that manage the computers, networks, and other technological aspects of their businesses. A BizOps department, or a department focused on business operations, has also been developed by companies to integrate IT with business outcomes.

A moral perspective

Information technology uses raise a number of ethical concerns, such as:

  • Those who download stored files without permission of the owners of the copyrights are breaking the law

  • Keeping track of employees' emails and Internet usage by employers

  • E-mails that are unwelcome

  • Databases being hacked by hackers

  • Users' online activities can be monitored by web sites that install cookies or spyware, which may be used by data brokers.
