ICT History

Information and Communication Technology Basics

ICT is often used as a synonym for information technology (IT), but the two terms can have slightly different meanings when used in different contexts.

In the United States, for example, the acronym ICT is used more often in education because, in that context, IT can also mean instructional technology. In some industries, IT only applies to enterprise computing, while the broader label ITC encompasses both IT and communication technologies.

Using IT and ICT interchangeably can lead to confusion, particularly in situations where the distinction between the two is important. For example, a job posting that requires expertise in IT may be different from one that requires expertise in ICT, as the latter may require additional skills that specifically support communication and collaboration tools.

ICT Basics

IT is often considered to be a subset of ICT that deals with the technical aspects of managing information, while ICT is a broader term that encompasses both IT and communication technologies.

While IT deals primarily with computer hardware, software, and networking technologies, ICT includes not only these technologies but also communication technologies such as telegraph, telephone, radio, and television.

ICT Infrastructure and Systems

Information and communication technology includes a wide range of information, telecommunication, and support tools and services that work together to facilitate communication.

This includes:

  • Hardware and software that supports the way information is created, disseminated, acquired, and stored.
  • Infrastructure and electronics that enable communication between hardware devices.
  • Protocols and interfaces that enable seamless communication and data exchanges between different hardware and software components.
  • Tools for protecting sensitive information and ensuring the integrity of an ICT system.
  • Standards for protecting data in transit, during processing, and at rest.
  • Governance policies for how information should be accessed, secured, processed, transmitted, and stored.
  • Workers who have the skills required to design, develop, maintain, and support ICT systems.

ICT infrastructure includes information technology, telecommunication technology and the services they support.

ICT Infrastructure

Centralized and Decentralized ICT

When ITC architectures are centralized, the hardware, software, and network infrastructure components that support communication are located in a single location, and users can only access these resources from that location. This approach was cost-efficient during the early days of computing when the cost of wired communication infrastructure was high, and mainframes had limited processing power.

Broadband Internet made it possible to decentralize ITC architectures. Once data could be transmitted faster and over greater distances, it became possible to store and access it remotely and run the same applications virtually on multiple remote servers. This led to increased adoption of unified communication systems (UCSs), cloud-based services, and new types of collaboration tools.

The increased bandwidth of broadband has also inspired new ways to use peer-to-peer (P2P) network architectures. In a P2P network, each node (or user) can act as both a server and a client and share information with other nodes without the need for a central server.

Today, this type of architecture is often associated with blockchain and cryptocurrencies, but it’s important to remember that P2P also plays an important role in the Internet of Things by allowing IoT devices to communicate with each other, share data, and perform complex tasks that individual devices cannot handle.

Centralized and Decentralized ICT

Impact of ICT on Society

ICT has reshaped the world’s economic landscape and workforce dynamics.

E-commerce has created new opportunities for businesses and consumers alike, supporting globalization by enabling transactions and interactions to occur across borders seamlessly. Smart cities are improving urban living by leveraging IT and communication technology to improve transportation, public services, and municipal infrastructure.

The combination of information technology and communication technology has had a lasting impact on society. As technology and collaboration tools continue to advance, organizations are finding it necessary to continually reevaluate their best practices for sharing digital information, and governments are continually looking for ways to reduce the digital divide.

Digital literacy has become a necessary skill for everyone. The digital economy has introduced new types of jobs, improved productivity, and allowed employees to collaborate remotely from just about anywhere they can connect to the Internet.

The environmental effects of ICT have also been profound. Data centers and electronic devices require significant amounts of power to operate, and the rapid growth and constant evolution of technology have led to a surge in e-waste as obsolete devices are discarded. This waste often contains hazardous materials that pollute the environment and can harm human health.

As IT and communication technologies continue to advance and become more like a necessary utility than something nice to have, individuals, organizations, and governments need to recognize both the benefits and challenges of ICT’s impact on society.
