Answer:
Physical means the actual wires. Physical is concerned with how the wires are connected. Logical is concerned with how they transmit.
Explanation:
Answer:
When the transmission exceeds 667 packets
Explanation:
In computer networking, a packet is a chunk of data transmitted across the network. The packet size of an Ethernet network is 1.5kilobytes, while the packet size of an IP packet payload is 64 kilobytes.
A switch is a physical network device that connects nodes or workstations while communicating the packets (or frames). The I/O bus size bandwidth is 1Gbps which allows approximately 667 packets. Once this packet size is crossed, the bus becomes a limiting factor or bottle neck.
Answer:
Hi DancingGrace! The issue with the code is that it is trying to extend multiple classes which is not a feature in Java programming.
Explanation:
The extends keyword allows a class to use the attributes and properties of the base class it is extending and add more features and properties into it's own class. This is useful in programming where different models share similar properties but are slightly different. An example would be designing a class for Car and Bike. Both have some similar properties like wheels, engine, etc, however they are different forms of transport. A useful implementation would be to define a class called Vehicle with similar attributes, and have the Car and Bike extend it.
