Networking Fundamentals Quiz

Study Notes

Protocols

A protocol is a set of rules that govern how data is transmitted over a network.

Network Devices

Hub: A simple device that broadcasts data to all connected devices.
Server: A device that provides resources to other devices on a network.
Router: A device that forwards data packets between networks.
Cables: Physical connections that transmit data between devices.

Bandwidth and Data Transmission

Bandwidth: The amount of data that can be transmitted over a network in a given time.
Bits per second (bps): A unit of measurement for data transmission speed.
Buffering: A temporary storage area for data, used when the rate of data arrival differs from processing rate.

Network Types

Wired networks use physical cables for connection, providing higher speed and security.
Wireless networks use radio waves for connection, providing flexibility but potentially slower speeds.

The Internet

The Internet is a global network connecting computer networks worldwide.

Network Protocols

MAC address: A unique identifier for a network interface card.
IP address: A unique identifier for a device on the internet.
TCP: A protocol that ensures reliable data transmission over the internet.
VoIP: A protocol that allows voice communication over the internet.

Data Transmission

Packet: A unit of data transmitted over a network.
A large amount of data is split into smaller units called packets for efficient transmission.

World Wide Web

The World Wide Web is a system of interconnected hypertext documents accessible via the internet.

Internet of Things (IoT)

IoT connects various devices to the internet, enabling data collection and exchange.
