Study Notes
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
