1 EN0129 PC AND NETWORK TECHNOLOGY I
DATA LINK LAYER AND PHYSICAL LAYER Derived From CCNA Network Fundamentals – Chapter 7 and 8

2 Data Link Layer – Accessing the Media
The service the Data Link Layer provides as it prepares communication for transmission on specific media

3 Data Link Layer – Accessing the Media
Why Data Link layer protocols are required to control media access

4 Data Link Layer – Accessing the Media
The role of framing in preparing a packet for transmission on a given media

5 Data Link Layer – Accessing the Media
The role the Data Link layer plays in linking the software and hardware layers

6 Data Link Layer – Accessing the Media
Sources for the protocols and standards used by the Data Link layer

7 Media Access Control Techniques
The necessity for controlling access to the media

8 Media Access Control Techniques
Two media access control methods for shared media and the basic characteristics of each

9 Media Access Control Techniques
Full Duplex and Half Duplex as it relates to Media Access Control for non-shared media

10 Media Access Control Techniques
The purpose of a logical topology and identify several common logical topologies

11 Media Access Control Techniques
Logical and physical topologies

12 Media Access Control Techniques
The characteristics of point-to-point topology and the implications for media access when using this topology

13 Media Access Control Techniques
The characteristics of multi-access topology and the implications for media access when using this topology

14 Media Access Control Techniques
The characteristics of ring topology and the implications for media access when using this topology

15 Media Access Control Addressing and Framing Data
The purpose of encapsulating packets into frames to facilitate the entry and exit of data on media

16 Media access control addressing and framing data
The role of the frame header in the Data Link layer and the fields commonly found in protocols specifying the header structure

17 Media access control addressing and framing data
The role of addressing in the Data Link layer and cases where addresses are needed and cases where addresses are not needed

18 Media access control addressing and framing data
The importance of the trailer in the Data Link layer and its implications for use on Ethernet, a "non-reliable" media

19 OSI Physical Layer

20 Physical Layer Protocols & Services
The purpose of the Physical layer in the network and the basic elements that enable this layer to fulfill its function

21 Physical Layer Protocols & Services
The role of bits in representing a frame as it is transported across the local media.

22 Physical Layer Protocols & Services
The role of signaling in the physical media.

23 Physical Layer Protocols & Services
Who establishes and maintains standards for the Physical layers compared to those for the other layers of the network

24 Physical Layer Protocols & Services
Hardware components associated with the Physical layer that are governed by standards

25 Physical Layer Signaling and Encoding
Network communication at this layer consists of individual bits encoded onto the Physical layer; and the basic encoding techniques.

26 Physical Layer Signaling and Encoding
The role of encoding as it applies to the transmission of bits and the value of treating a collection of bits as a code.

27 Physical Layer Signaling and Encoding
The terms bandwidth, throughput, and goodput

28 Characteristics & Uses of Network Media
Media characteristics defined by Physical layer standards.

29 Characteristics & Uses of Network Media
