TCP/ IP is a foundational protocol suite enabling internet communication organized into layers such as the Network Layer for addressing and subnetting featuring protocols like ARP RARP ICMP and IGMP. The Transport Layer encompasses TCP and UDP facilitating reliable and connection-oriented or lightweight connectionless data transmission. At the Application Layer the client-server model is prominent with protocols like BOOTP DHCP DNS TELNET FTP SMTP and HTTP serving various functions. Core Java fundamentals including operators control statements classes inheritance and exception handling are essential while Advanced Java delves into threading networking TCP/ IP sockets URL handling and caching proxy servers. Applets and JDBC expand on Java capabilities with Applets introducing GUI components and JDBC enabling database connectivity and query execution. CGI programming with Perl underpins web architecture alongside network security considerations encompassing cryptography encryption decryption RSA algorithm digital signatures and firewall architecture for organizational security.
