Network Protocols Flashcards
They define rules and conventions for data transfer between
network devices, ensuring successful and secure data communication.
Protocols
Network protocols can be broadly grouped into three categories
Communication Protocols
Security Protocols
Management Protocols
These control the format and transmission of data.
Communication Protocols
These help protect data as it traverses networks.
Security Protocols
These help maintain and govern network resources.
Management Protocols
OSI meaning
Open Systems Interconnection Model
It’s a conceptual framework used to understand network
interactions in seven layers:
OSI Model
OSI Model Seven Layers
Physical Layer
Data Link Layer
Network Layer
Transport Layer
Session Layer
Presentation Layer
Application Layer
: Deals with the physical connection between devices and the
transmission of binary data over those connections.
Physical Layer
: Provides error detection, flow control, and frames the data.
Data Link Layer
Manages routing, forwarding, and addressing.
Network Layer
Ensures data is transferred completely and correctly.
Transport Layer
Manages sessions and controls dialogues between computers.
Session Layer
Translates data formats and encrypts/decrypts data
Presentation Layer
Provides services for applications to exchange data.
