ICT Notes

Information & Communication Technology (ICT)

What is ICT?

  • ICT stands for Information & Communication Technology.
  • It encompasses the infrastructure and components that enable modern computing.
  • ICT refers to technologies providing access to information through telecommunications.
  • It is similar to Information Technology (IT) but focuses primarily on communication technologies like the Internet, wireless networks, and cell phones.
  • Cambridge dictionary definition: ICT refers to technologies that provide access to information through telecommunications.
  • Techopedia definition: ICT refers to all the technology used to handle telecommunications, broadcast media, intelligent building management systems, audiovisual processing and transmission systems, and network-based control and monitoring functions.

Uses of ICT in Daily Life

Communication

  • Old Means of Communication:
    • Letters
    • Telephone
    • Radio
    • Television
    • Mobile phones
    • Newspapers
  • New Means of Communication:
    • Chatting, E-mail, voice mail, and social networking.
    • Cellular phones designed for communicating with people miles away.

Education

  • ICT allows students to monitor and manage their own learning.
  • Provides students from remote areas access to expert teachers and learning resources.
  • ICT can impact student learning when teachers are digitally literate and understand how to integrate it into the curriculum.
  • Schools use a diverse set of ICT tools to communicate, create, disseminate, store, and manage information.
  • ICT utilizes approaches such as:
    • Replacing chalkboards with interactive digital whiteboards.
    • Using students’ own smartphones or other devices for learning during class time.
    • The "flipped classroom model" where students watch lectures at home and use classroom time for more interactive exercises.

Job Opportunities

  • Employing staff with ICT skills is crucial in the employment sector.
  • Example: Pharmacies using robot technology to assist with picking prescribed drugs, allowing pharmaceutical staff to focus on jobs requiring human interaction and intelligence, such as dispensing and checking medication.

Socializing

  • Social media has changed:
    • How we find partners
    • How we access information
    • How we organize to demand political change
  • Young people can maintain social connections and support networks.
  • Social interactions young people have online can be invaluable for bolstering and developing their self-confidence and social skills.

Impact of ICT in Society

Positive Impacts

  • Access to information:
    • Better and cheaper communications, such as Voice over Internet Protocol (VoIP) and Instant Messaging.
  • Improved access to education:
    • E.g., distance learning and online tutorials.
  • New tools, new opportunities:
    • ICT gives access to new tools like digital cameras, photo-editing software, and high-quality printers.
    • Screen magnification or screen reading software enables partially sighted or blind people to work with ordinary text rather than Braille.
  • Communication:
    • Cost savings by using:
      • VoIP instead of normal telephone.
      • Email/messaging instead of post.
      • Video conferencing instead of traveling to meetings.
      • E-commerce websites instead of sales catalogs.
    • Access to larger, even worldwide markets.
  • Information management:
    • Data mining of customer information to produce lists for targeted advertising.
    • Improved stock control, resulting in less wastage and better cash flow.
  • Security:
    • ICT solves or reduces some security problems.
      • Encryption methods can keep data safe from unauthorized people, both during storage and electronic transmission.
  • ICT allows people to participate in a wider, even worldwide, society.
  • Distance learning:
    • Students can access teaching materials from all over the world.
  • ICT facilitates the ability to perform ‘impossible’ experiments by using simulations.
  • Creation of new more interesting jobs, such as systems analysts, programmers, software engineers, help desk operators, and trainers.

Negative Impacts

  • Job loss:
    • Manual operations being replaced by automation.
      • E.g., robots replacing people on an assembly line.
  • Job export:
    • Data processing work being sent to other countries where operating costs are lower.
  • Multiple workers being replaced by a smaller number who are able to do the same amount of work.
    • A bar-code scanner linked to a computerized till is used to detect goods instead of the worker having to enter the item and price manually.
  • Reduced personal interaction:
    • Most people need some form of social interaction in their daily lives; without it, they may feel isolated and unhappy.
  • Reduced physical activity:
    • This can lead to health problems such as obesity, heart disease, and diabetes.
  • Cost:
    • A lot of ICT hardware and software is expensive to purchase and maintain.
  • Competition:
    • Organizations may lose out to others that can offer the same service for less money nationally or internationally.
