called a ______.
network
architecture, protocol stack,
The information sent
on each level is called a ____.

was created by the International
Organization for Standardization (ISO),
an international standard-setting body
OSI (Open Systems Interconnection)
model
It
was designed to be a reference model for
describing the functions of a
communication system.
OSI (Open Systems Interconnection)
model
model was created in the
1970s by the Defense Advance
Research Project Agency (DARPA) as
an open, vendor-neutral, public
networking model.
The TCP/IP
TCP/IP layers:
Network Access, Internet, Transport, and
Application
OSI layers:
Application, Presentation, Session, Transport, Network, Data Link, Physical
In ____, they are 4 bytes, or octets, in length. It is
common to write _____ addresses in dot-decimal
notation, such as 128.252.73.216
IPv4
addresses are customarily written as eight groups of
four hexadecimal digits separated by colons, such as
2002:80fc:a0ba::80fc:a0ba (one sequence of groups
consisting of four 0 digits can be omitted, as in this
example; leading zeros can always be omitted).
IPv6
IANA in turn grants IP address
allotments to five regional
registries:
African Network Information Centre (AfriNIC)
* American Registry for Internet Numbers (ARIN) for
the United States, Canada, and parts of the Caribbean
* Asia-Pacific Network Information Centre (APNIC)
* Latin American and Caribbean Internet Addresses
Registry (LACNIC) for Latin America and parts of
the Caribbean
* RIPE NCC for Europe, Central Asia, and the Middle
East
The Models
- Client-Server
- Peer-to-Peer
- Group Multicast
______ involves the
exchange of request-reply messages
according to the following sequence
client-server pattern
The client-server pattern involves the
exchange of request-reply messages
according to the following sequence.
- Client: Transmit a request to the
server process and block. - Server: Execute the request.
- Server: Return the reply to the client
follows naturally
from the client-server model.
