EXAMPLE:

We set up a LAN at the office so all the computers can share files and printers more easil

EXAMPLE:

Imagine you live in a house with a fence and a gate. The fence surrounds your property, and the gate is controlled by a security guard. Only people who are on a guest list are allowed to enter. The security guard checks everyone's ID and purpose for visiting before letting them in. In this scenario, the firewall is like the security guard and the gate it decides who or what can enter your home (network) and who is blocked.

• Definition: A network that spans a large geographic area, such as cities, countries, or even continents.

• Example: The Internet is the largest WAN.

EXAMPLE:

Imagine you have a refrigerator door. When the door is closed, the light inside the fridge turns off automatically. But when you open the door, the light turns on instantly. This happens because there's a small magnetic switch inside called a 'red switch.' When the door is closed, a magnet keeps the switch in the off position, but when the door opens, the magnet moves away, and the switch activates the light.

A hotspot is a location where devices can connect to the internet for WiFi. It can be a public or private network, such as in cafes, airports, or hotels.

You're at a hotel that offers a Wi-Fi hotspot in the lobby. You check in and head to the lounge area, where you connect your tablet to the hotel's Wi-Fi network. This Wi-Fi hotspot provides internet access to hotel guests, allowing them to browse the web, check emails, or stream videos while they relax in the lobby.

In this case, the hotel’s Wi-Fi acts as a hotspot, allowing multiple devices to connect to the internet through a single connection point.

Ex: 167. 36. 214. 8.

TCP is a protocol used to send data between computers over the internet. It makes sure that the data is delivered completely and in the correct order. Imagine sending a letter in many pieces—TCP checks that all pieces arrive and puts them back together. It also resends any pieces that are lost. This is why TCP is reliable, but it can be a bit slower than other protocols.

• Definition: A specific location where wireless internet is available, typically via Wi-Fi.

• Example: A café or public park with free Wi-Fi.

Example: A data center offering cloud storage services. Servers and storage devices are connected via a SAN to ensure fast and reliable access to large volumes of data.

The Domain Name System is complex system that translate domain names to IP addresses, so, browsers and other systems can request data to that endpoint

A DNS (Domain Name System) is a system that translates domain names (like google.com, etc) into IP addresses. It allows devices can connect to websites and online services.

A broadband modem is a device that connects your home or office to the internet via your internet service provider (ISP). It converts data from your ISP into a usable form and allows high-speed internet access. It can be connected to a router for Wi-Fi or directly to a device via Ethernet.
