Networking Questions

The speed of the transmission data is generally determined by the cables or connectors we use for data transmission. In networking, layer-1 the physical is which deals with the network cables like pins, usb, connectors, etc... we use for data transmission.

The logical arrangement of the nodes of different networks to communicate is called as topology.

The data unit created at the application layer is called a message, at the transport layer the data unit created is called either a segment or an user datagram, at the network layer the data unit created is called the datagram, at the data link layer the datagram is encapsulated in to a frame and finally transmitted as signals along the transmission media.

10Base2—An Ethernet term meaning a maximum transfer rate of 10 Megabits per second that uses baseband

signaling, with a contiguous cable segment length of 100

meters and a maximum of 2 segments.

10Base5—An Ethernet term meaning a maximum transfer rate of 10 Megabits per second that uses baseband

signaling, with 5 continuous segments not exceeding 100

meters per segment.

10BaseT—An Ethernet term meaning a maximum transfer rate of 10 Megabits per second that uses baseband

signaling and twisted pair cabling.

The OSI Model is used as a reference model.

The primary reason the OSI model was created was so that different networks could inter-operate. Hence, different networks could communicate.

The address resolution protocol (ARP) is used to associate the 32 bit IP address with the 48 bit physical address, used by a host or a router to find the physical address of another host on its network by sending a ARP query packet that includes the IP address of the receiver.

The reverse address resolution protocol (RARP) allows a host to discover its Internet address when it knows only its physical address
