Types of Networks
This type of network connects devices in a small geographic area like a home or school.
What is LAN?
Short-range wireless technology used in smartwatches and speakers.
What is Bluetooth?
This is a set of rules that govern data communication.
What is a protocol?
I ensure compatibility between systems and manufacturers?
What are network standards?
This security method scrambles data, while another verifies a user’s identity.
What are encryption and authentication?
This network spans large geographic areas such as cities or countries.
What is WAN?
A city-wide wireless network.
What is MAN? (Metropolitan Area Network)
This protocol splits data into packets and ensures delivery.
What is TCP/IP?
The 4 layers of the TCP /IP model.
What are application, transport, internet, physical layers?
This wireless network security feature allows or blocks devices based on their hardware address.
What is MAC address filtering?
A logical grouping of devices in a LAN to segment traffic and improve security.
What is VLAN?
A decentralized wireless structure that connects nodes directly.
What is Mesh Network?
A method where data is sent in small chunks across different routes.
What is packet switching?
This 7-layer framework standardizes communication functions to allow interoperability between systems.
What is the OSI Model?
These three wireless security methods vary in effectiveness—one scrambles data, one verifies users, and one filters devices.
What are encryption, authentication, and MAC filtering?
This type of network connects storage devices across a high-speed backbone.
What is SAN?
A wireless local area network used in homes and schools.
What is WiFi?
This is done in order to reduce transmission time and bandwidth usage?
What is data compression?
These are the 3 of the key technologies required to establish a secure Virtual Private Network.
What are VPN client software, tunneling protocols, authentication, and/or encryption?
These benefits include mobility and convenience, while drawbacks include interference and reduced security.
What are the pros and cons of wireless networks?
A network model where users share files directly without a central server.
What is P2P?
High-speed mobile networks that support streaming and video calls.
What are 3G/4G/5G?
Define data integrity, flow control, deadlock, congestion, and error checking.
What are key protocol functions that maintain reliable communication?
This service provides privacy and secure communication over the internet, but may reduce speed and device compatibility.
What is a VPN?
These three transmission media differ in speed, cost, reliability, and security—one is optical, one is electrical, and one is untethered.
What are fiber optics, metal conductor, and wireless transmission media?
