GRADED A+
OSI Model Transport Layer - ANSWERS-- Responsible for the
end-to-end communication between end hosts.
- 2 protocols, TCP and UDP.
- TCP includes a connection-oriented service to the
applications that are running on the layer above,
guaranteed delivery of the application-layer messages, flow
control, and congestion control mechanism.
,- UDP provides a connectionless, best-effort service to the
applications that are running in the layer above without
reliability, flow, or congestion control.
- In this layer the packet is called a segment.
OSI Model Data Link Layer - ANSWERS-- Packets are referred
to as frames.
- Examples include:
- ethernet,
- ppp,
- wifi.
- Responsible for moving the frames from one node (host or
router) to the next node.
- Services offered by the ___________ layer protocol include
reliable delivery (transmission of the data from one
transmitting node, across one link, to the receiving node.
,OSI Model Physical Layer - ANSWERS-This layer is the actual
hardware responsible to transfer bits within a frame
between two nodes c
Provide examples of popular protocols at each layer of the
five-layered Internet model. - ANSWERS-Application: NFS,
DNS, SNMP, ftp, rcp, telnet, HTTP
Transport: TCP, UDP
Internet: IP, ARP, ICMP
Data Link: PPP, IEEE 802.2, Ethernet
Physical Network: Token Ring, RS-232

What is encapsulation, and how is it used in a layered
model? - ANSWERS-Encapsulation is when data (called a
header) is appended to the packet through each layer to
signify its on the correct path to the destination host.
