    Study Notes

    Internet and Networks

    • The Internet is a collection of networks.
    • Networks are a group of devices connected by cable, WiFi, or satellite.
    • Open protocols are used to standardize data transmission across devices on the internet.
    • Open protocols ensure equal bandwidth for all users and secure data transmission.
    • The World Wide Web is a system of interconnected pages, programs, and files accessed via the Internet.

    Programming Concepts

    • If statements: Used to evaluate conditions and execute specific code based on the outcome.
    • Loops (iteration): Used to repeat a section of code. Can be based on a condition or a set number of times.
    • Variables: Used to store data that can change in programming.
    • Data types: There are different types of data a variable can hold. A variable used to store a person's age should be a Number.

    Lists

    • Lists are a way to store multiple values.
    • Lists are dynamic, meaning their size can change.
    • Lists are easily manipulated using loops.

    Additional Information

    • Programming languages: SNAP!, Java, Python, and Assembly are examples. Certain programming languages are relatively easier to learn for beginners, like SNAP!.
    • Fault tolerance: Network fault tolerance relies on multiple paths between devices, allowing for routing to occur even if one part of the network is down.
