Study Notes

Information & Communications Technology (ICT)

ICT is broader than just electronics, including communication and how information is managed.
It improves decision-making, business processes, and daily living.
Devices like mobile phones, laptops, and tablets are essential across different ICT applications.
The "belongingness hypothesis" explains this need for connectivity based on a desire to connect with others.

Computer Basics

A computer is an electronic device that manipulates information or data.
It has hardware, physical components, and software, programs and instructions.
Input devices like keyboards, mice, and touchpads interact with the computer and send information to it.
Output devices like monitors and speakers receive information from the computer.

Computer Hardware

The CPU (Central Processing Unit) is the "brain" of the computer where calculations occur.
Hardware components like the motherboard, RAM, and storage devices work together to ensure the computer functions correctly.

Computer Networks

Computers can communicate with each other via networks.
A computer network is two or more computers sharing information and resources.
Different types of networks exist based on size, purpose, and technology used.
PAN (Personal Area Network) connects devices like smartphones, laptops, and tablets for personal use.
LAN (Local Area Network) connects computers and other devices like printers in a confined area like a building.

The Internet

The Internet is a global network connecting millions of computers.
Large internet service providers (ISPs) like PLDT in the Philippines, own the infrastructure for delivering internet access.
Over 4 billion people globally use the internet for various purposes, including communication, information access, entertainment, and e-commerce.
The internet has evolved significantly but its basic functioning remains similar.
