Study Notes
Information Technology Literacy
- Information Technology Literacy refers to the ability to use, manage, understand, and assess technology.
- It is closely related to digital literacy, which involves proficiency in using computers and digital devices to access the Internet.
- Digital literacy enables users to discover, review, evaluate, create, and utilize information through various digital platforms, including web browsers, databases, and social media.
Computer Systems
- A computer is a programmable electronic device designed to receive, store, process, and display data or information.
- Components of a computer system include:
- Hardware: Physical components such as CPU, memory modules, printers, and hard disks.
- Software: Instructions that dictate how a computer operates; categorized into system software (e.g., operating systems like Windows) and application software (e.g., word processors like MS Word).
- Hardware and software are interdependent; hardware requires software to perform tasks, while software functionality is bounded by hardware capabilities.
Internet Overview
- The term "Internet" derives from "inter" (Latin for "between") and "net" (short for "network"), designating it as a connection between networks.
- The Internet is a vast global network comprising billions of computers and devices, enabling access to information, communication, and various online activities.
- The ARPANET, the precursor to the Internet, was launched in 1969 by the Advanced Research Projects Agency (ARPA) and utilized the Transmission Control Protocol (TCP/IP).
Intranet and Extranet
- Intranet: A private network accessible only to an organization's members, used for internal communication and information sharing.
- Extranet: A controlled private network allowing limited access to outsiders, facilitating collaboration between organizations and partners.
- Illustrations can differentiate infrastructure between Intranet, Extranet, and Internet, outlining their respective access and connectivity.
Basic Networking Equipment
- Essential equipment for network setup typically includes routers, switches, and other devices that facilitate network connectivity and communication.
Applications of ICT
- ICT enhances communication, making it more connected and cost-effective compared to past methods like phone calls and postal mail.
- Communication is categorized into Direct and Indirect Communication.
Direct Communication
- Requires simultaneous participation from both sender and recipient.
- Examples include:
- Real-time messaging applications facilitating instant messaging.
- Voice over IP (VoIP) enabling affordable voice calls via the Internet.
- Video conferencing allowing geographical users to hold meetings in real-time.
Indirect Communication
- Sender and recipient do not need to be synchronized; messages can be retrieved later.
- Examples include:
- World Wide Web (WWW) for information access.
- Email for asynchronous messaging.
- File sharing and social networking for content distribution.
Virtual Reality (VR)
- VR technology is embedded in various fields, enhancing experiences through immersive environments.
- Key applications include:
- Military training simulating combat situations.
- Education using VR for therapeutic exercises and learning enhancement.
- Healthcare through 3D modeling for surgical planning and patient education.
- Entertainment, engineering, fashion, telecommunications, and more.
Virtual Reality Devices
- Essential equipment includes headsets, which can be:
- High-quality models connected to computers.
- Affordable types using a cell phone.
- Headsets require good quality headphones for an immersive experience.
- Hand controllers translate physical gestures into VR environments.
- Leading VR brands include HTC Vive, Oculus Rift, and PlayStation VR (PSVR).
Virtual Reality in the Military
- VR is utilized across all military branches for training without real-world risks.
- Key training applications:
- Flight simulators for pilot training.
- Battlefield simulations for combat scenarios.
- Medic training for emergency medical response in combat.
- Vehicle operation training.
- Virtual boot camps for foundational training.
Virtual Reality in Healthcare
- Surgical theatres use VR to convert medical imaging into 3D models for surgical planning and patient communication.
Virtual Reality in Education
- Institutions like the Jackson School in Australia use Oculus Rift for special needs education, while Polish universities implement VR technology for therapeutic exercises with autistic students.
