1. Discuss the purpose of subnetting. What does CIDR stand for
and mean?
Discuss the use of ARP, TCP, UDP, FTP, HTTP, and Telnet.
How does TCP ensure reliable delivery? Name a few TCP
protocols. What is TCP's "counterpart" that does not ensure
reliable delivery? Name a few of these protocols.
Discuss the purpose of subnetting.
In a subnet, the hosts may be on different physical networks but
share a single network number. Each host in the subnet is
configured with an IP address and Subnet mask.
Discuss the use of ARP, TCP, UDP, FTP, HTTP, and Telnet.
The Application layer consists of protocols that focus on
process-to-process communication across an IP network and
provides a firm communication interface and end-user services.
These services are sub protocols with specific goals.
ARP (Address Resolution Protocol) is responsible for resolving
internet addresses into link layer addresses. It is also used for
mapping a network address to a physical address.
TCP (Transmission Control Protocol) is connection-oriented,
reliable communications service responsible for the

2. establishment of a TCP connection, the sequencing and
acknowledgement of packets sent, and the recovery of packets
lost during transmission.
UDP (User Datagram Protocol) is used when the amount of data
to be transferred is small, or when the applications or upper
layer protocols provide reliable delivery.
FTP (File Transfer Protocol) allows files to be transferred
between computers
HTTP (Hypertext Transfer Protocol) is used to transfer web
pages to end-users.
Telnet is a bi-directional text communication via a terminal
application; it’s used for logging on remotely to network hosts.
How does TCP ensure reliable delivery?
The TCP provides reliable communications services by
providing sequencing services to the packets sent as well as an
acknowledgment service. When the correct response is not
received, TCP process the packet again to assure the requested
transfer happens.
