4. provides detailed implementation
specifications for a number of networking
technologies
Influential set of networking standards
Guide to Networking Essentials, Fifth Edition 4
5. The IEEE defined a set of LAN standards to
ensure network interface and cabling
compatibility
Project 802 (inception on February (2) of 1980)
▪ Concentrates on standards that describe a network’s physical
elements
▪ NICs, cables, connectors, signaling technologies, media access
control, and the like
OSI model was not standardized until 1983–1984
IEEE 802 standards predate the model
Both were developed in collaboration and are
compatible with one another

8. MediumAccess Control
collisions
Data Communications Protocol
A protocol must also exist for transmitting data
once the node has gained control of the medium
and is able to transmit.
Guide to Networking Essentials, Fifth Edition 8
12. Ethernet
CSMA/CD – Carrier Sense MultipleAccess
with Collision Detection
Terminates transmission when it detects collision
Guide to Networking Essentials, Fifth Edition 12
13. Token Bus
Implementing a token ring protocol on a
coaxial cable
Used for industrial applications
Used by General Motors in their MAP
(ManufacturingAutomation Protocol)
Not reliable

15. Demand Priority or High Speed Networking
100Mbps Ethernet standard over Category
3UTP
Also called 100VG AnyLAN
Carries both Ethernet andToken Ring

16. The OSI reference model and IEEE Project 802
define a frame of reference for networking and
specify the lower-layer behaviors for most
networks
Together, these models describe the complex
processes and operations involved in sending and
receiving information across a network
The OSI reference model separates networking
into seven layers, each with its own
purposes/activities
From the bottom up: Physical, Data Link, Network,
Transport, Session, Presentation, and Application
Guide to Networking Essentials, Fifth Edition 16
17. Data frames consist of three parts: frame header,
data section, and frame trailer
Classified as unicast, multicast, or broadcast frames
The IEEE 802 project elaborates on the functions
of a network’s Physical and Data Link layers by
dividing the Data Link layer into two sublayers:
Logical Link Control (LLC) and Media Access
Control (MAC)
Together, these sublayers handle media access,
addressing, and control and provide reliable, error-free
delivery of data frames from one computer to another
