Networking Exam 3 Ch 6.2

Front 1

distances and speed

Back 1

Physical Layer Standards differ by _______________

Front 2

Physical layer standards list

Back 2

- baseband
- broadband
- Link Aggregation / Trunking / Bonding
- Sending Signal using Multiple Links and Multiple Switches

Front 3

Baseband Transmission

Back 3

- dominant Ethernet transmission
- signal put directly onto the line
- with UTP, change voltage levels; with optical fiber, turn light on or off.
- less expensive, simpler, signal can be regenerated for distance

Front 4

Broadband transmission

Back 4

- the signal is modulated into a radio channel and
sent in a radio channel.
- Signal must be translated/changed/modulated before being put on the line
- Carries signals farther

Front 5

Link Aggregation / Trunking / Bonding

Back 5

- Sending Signal using Multiple Links and Multiple Switches
- Receiving signal is different than the sent signal due to attenuation
- Regeneration is necessary – different from amplification
- Allows the message to be sent farther

Front 6

Data Link Layer sublayers

Back 6

- LCC (Logical Link Control)
- MAC (Media Access Control)

Front 7

LCC (Logical Link Control)

Back 7

- handles general work for all 802 standards.
- There is a single standard: 802.2.
- in practice, it has no significance for Ethernet LAN managers

Front 8

MAC (Media Access Control)

Back 8

– 802.3 - Standard-Specific matters, specific to the hardware; Ethernet has only 1 ____ layer standard

Front 9

MAC consists of

Back 9

- Details how the data is put together
- 48 bit Destination MAC address (Hexadecimal Notation)
- 48 bit Source MAC address (Hexadecimal Notation)

Front 10

is MAC reliable?

Back 10

no; allows for error detection but not correction
