Types of Internet Connections

Computer Networks

• Wireless networks don't require cables and use signals between computers and Wireless Access Points (WAPs)
• Mobile phones can connect to the internet anywhere with a phone signal
• To connect to a network, you need a username and password for a school network, or a network name and security key for a home network

Cloud Storage

• Cloud storage allows you to save files online, which are stored on large storage devices in a data centre
• Advantages include accessing files from anywhere with an internet connection, sharing files with others, and automatic backup
• Cloud services include collaboration, software applications, web hosting, music, videos, and games

Cloud Services

• Collaboration tools allow people to work together and hold web conferences
• Software applications make sharing documents and files easier
• Web hosting provides technical knowledge and web editing software for creating websites
• Music, videos, and games can be streamed and used for multi-player gaming

Advantages of Cloud Storage

• Files are accessible from anywhere with an internet connection
• Collaboration and sharing data is easy
• Data is safe and backed up
• Low cost to start, with technical support provided
• Company provides technical help

Disadvantages of Cloud Storage

• Service might not meet exact needs
• Service provider can change how it works and increase costs
• Can be expensive over time

Simulations

• Simulations imitate real-life scenarios, allowing changes to be made and observations to be repeated
• Advantages include being able to conduct experiments anywhere, repeat experiments, speed up processes, and not needing equipment

Virtual Reality

• Virtual reality creates a world around you, similar to simulations
• With a VR headset, you can explore and learn in a virtual world

Assistive Technology

• Assistive technology helps people with disabilities
• Examples include software that enlarges on-screen text, screen readers, braille converters, and speech generators

Space Discovery

• The Apollo Guidance Computer (AGC) was built to guide astronauts to the moon and back
• Modern computer chips are more powerful than the AGC
• Robots are used to explore planets

Predicting Natural Disasters

• Satellites and radar record weather conditions, which are processed using algorithms to predict natural disasters
• Computers play a crucial role in predicting and preparing for hurricanes and other disasters

Computer Systems

• A broadband network connects you to the internet at home
• A server stores and sends computer files and messages to users and devices
• The server ensures files reach their intended recipients

Network Devices

• Hubs send messages to every connected computer, which can slow down the network and pose security risks
• Switches send messages only to the intended recipient, providing more security and speed
• Routers connect networks together, while modems translate data between networks
• Wireless Access Points (WAPs) allow wireless connections, and several computers can connect at one point
• Local Area Networks (LANs) are larger than home networks and are not stored in a single case
• Copper cables are commonly used in networks, while fibre-optic cables provide faster connections
