CLOUD STORAGE VOCABULARY

What are servers?

• A server is like that librarian—but for computers!

  • When you use your computer, tablet, or phone to open a website or play a game, your device is asking for something.

  • The server is a special computer that stores all the stuff—like web pages, pictures, or game data.

  • It listens for your request, finds what you asked for, and sends it back to your device. The term "server" can refer to both the hardware (a physical machine) and the software (a program) that performs this role.

• A server is a person who brings you food at a restaurant.

• A server is a service that you receive when you purchase something

📡 How Do Digital Devices Talk Without Wires?

• Digital devices—like phones, tablets, and laptops—can send and receive data without using any wires. They do this using something called radio waves.

• "The devices shout messages really loudly so other devices can hear them."
  📣

• "They use invisible strings that stretch across the sky."
  

• "Tiny messenger pigeons fly the data from one phone to another."

Two Common Ways Devices Use Radio Waves:

• WIFI

  • Wi-Fi connects your device to the internet at home or school.

  • It uses radio waves to talk to a router, which then connects to the internet.

  • Example: When your tablet connects to the internet without a cable, it's using Wi-Fi!

• CELLULAR NETWORK

  • Used by phones and tablets with SIM cards.

  • Sends signals to cell towers that are spread all over.

  • Lets you make calls, send texts, or use the internet almost anywhere, even when there's no Wi-Fi.

Explain how bandwidth affects network performance.

• Bandwidth is like the size of a road that internet data travels on. More bandwidth = faster, smoother internet.

• A small road (low bandwidth) can only fit a few cars at a time—so things go slower and get crowded.

  Less bandwidth = slower, choppy internet.

• Bandwidth is like the size of a road that internet data travels on. More bandwidth = slower, choppy internet connection.

• A small road (High bandwidth) can fit more cars at a time—so things go faster and get smooter.

  More bandwidth = slower, choppy Internet.

• What happens if too many devices connect to the same network?

• • The internet gets slower – like waiting in a long line.

• • Videos might pause (buffering).

• • Websites can take a long time to load.

• • Games might freeze or lag.

• • Video calls can become choppy or lose sound.

• Explain how and why we keep data secure during transmission.

• • To keep things like:

    • Passwords safe

    • Private messages private

    • Bank info or schoolwork protected

• Prevent hackers from stealing or changeing what we send or have.

• • We use something called encryption.( turns data into secret code while it’s being sent.)

• • So that everyone can have access to that data.

• • Hiding our data even from ourselves prevents hackers from accesing it.

• Choose the different types of Authentication:

• • Fingerprint

  • (You press your finger on a special sensor.

  • The device checks your fingerprint (which is unique to you!).

  • Like using your thumbprint as a key.)

• Facial Recognition 😊

  (The camera scans your face to make sure it’s you.

  • If your face matches the one it remembers, you’re in!

  • Like your face is your password.)

• • Password 🔑

  • (You type in a secret word or phrase.

  • If it matches, the device lets you in.

  • Like using a secret code to open a treasure chest or Teams)

• • Morse Code

  • (Sending text messages by form of taps)
