Study Notes
- ICT (Information & Communication Technology) facilitates information transfer and mediated communication.
Uses of ICT
- Communication involves transmitting messages through verbal and non-verbal means.
- Prehistoric communication used signs, symbols, cave paintings, and rock art.
- Communication has evolved from sending letters via post mail to using cellular phones.
- ICT enhances organizational operations by employing staff with ICT skills.
- Effective ICT use allows employees more time to focus on essential tasks.
- ICT integrates digital literacy and curriculum understanding for students.
- Schools utilize ICT tools for communication, creation, dissemination, storage, and management of information.
- Social media's rapid adoption changes how people find partners, access news, and organize political change.
5 Basic Computer Periods/Generations
- First Generation computers used vacuum tubes for circuitry and magnetic drums for memory.
- These computers occupied entire rooms and were expensive and unreliable.
- Input relied on punch cards and paper tape; output on printouts.
- Second Generation replaced vacuum tubes with transistors.
- Transistors made computers smaller, faster, cheaper, and more reliable.
- Second-generation computers shifted from machine language to symbolic language.
- Third Generation was marked by developing integrated circuits.
- Transistors were miniaturized and semiconductors increased speed and efficiency substantially.
- Users interacted via keyboards and monitors, with a central program monitoring memory.
- Fourth Generation used microprocessors, integrating thousands of circuits onto a single silicon chip.
- Fifth Generation is based on Artificial Intelligence (AI), using parallel processing and superconductors.
