No, Java does not support multiple inheritance. However, interfaces can inherit multiple interfaces.

• Java does not allow a class to inherit from multiple classes.

• This is because multiple inheritance can lead to ambiguity and conflicts.

• However, a class can implement multiple interfaces in Java.

A router is a networking device that forwards data packets between computer networks.

• A router operates at the network layer of the OSI model.

• It uses routing tables to determine the best path for data packets to reach their destination.

• Routers can connect multiple networks together, such as LANs and WANs.

• They provide network address translation (NAT) to allow multiple devices to share a single public IP address.

• Routers ...read more

Subnetting is the process of dividing a network into smaller subnetworks, called subnets, to improve network efficiency and security.

• Subnetting allows for better utilization of IP addresses by dividing a network into smaller segments.

• It helps in improving network performance by reducing network congestion.

• Subnetting enhances network security by isolating different departments or devices within a network.

• It enables effi...read more

Protocols are a set of rules and guidelines that govern the communication between devices or systems.

• Protocols define the format and order of messages exchanged between devices.

• They ensure reliable and efficient communication by specifying error detection and correction mechanisms.

• Examples of protocols include TCP/IP, HTTP, SMTP, and FTP.

• Protocols can operate at different layers of the network stack, such as the applic

Static protocols are fixed and do not change, while dynamic protocols can adapt to changing network conditions.

• Static protocols are typically used in simple networks with predictable traffic patterns.

• Dynamic protocols are used in complex networks with varying traffic patterns.

• Examples of static protocols include ARP and RARP.

• Examples of dynamic protocols include OSPF and BGP.
