1. Networking Basics Flashcards
What is a network?
A system that connects two or more devices to share data, resources, and services.
What are the key components required for a network to function?
Protocols (e.g., TCP/IP), hardware (e.g., routers, switches, cables), and devices (e.g., computers, servers).
What is a packet, and why is it important in networking?
A packet is a small unit of data transmitted across a network, allowing efficient, reliable communication by dividing larger messages.
What is the role of protocols in networking?
Protocols establish rules for communication, ensuring data is sent, received, and interpreted correctly.
What is the role of hardware like routers and switches in a network?
Routers forward packets between different networks, while switches connect devices within the same network and forward frames based on MAC addresses.
Why is data broken into packets in modern networking?
Breaking data into packets allows for more efficient use of bandwidth, easier error correction, and reliable data transmission.
What is a primary reason for using layered models in networking?
Layered models separate responsibilities into manageable layers, simplifying the design, implementation, and troubleshooting of networks.
