FUNDAMENTALS & LINK LAYER
Building a network – Requirements - Layering and protocols - Internet Architecture –Network software – Performance ; Link layer Services - Framing - Error Detection – Flow control.
BUILDING A NETWORK
Networks:
A network is a set of devices connected by a media link. Devices often referred to as nodes can be a computer, printer, or any other devices capable of sending/ receiving data.
Distributed processing:
Here tasks are divided among multiple computers. Each separate computer handles a subset.
Advantages:
1. Security/ Encapsulation
2. Distributed database
3. Faster problem solving
4. Security through redundancy
5. collaborative processing
