Protocols support seamless operations in computer network infrastructure. They handle data transmission and maintain network functionality effectively.
Communication Protocols
Communication protocols are essential for network operations10. Here are some key examples:
TCP (Transmission Control Protocol): Separates data into packets for network sharing10
IP (Internet Protocol): Routes and addresses data packets across networks10
HTTP: Facilitates communication between browsers and servers10
Management Protocols
Network management protocols help admins monitor and control network infrastructure11. Notable protocols include:
SNMP (Simple Network Management Protocol): Allows monitoring of network devices10
ICMP (Internet Control Message Protocol): Used for network diagnostics10
Security Protocols
Security protocols safeguard data integrity and confidentiality across networks11. Key protocols are:
SSL (Secure Socket Layer): Ensures secure internet connections through encryption10
HTTPS: Encrypts data between browsers and servers10
SFTP: Encrypts file transfers and authenticates interactions10
