Project description
Unit 1 Lab Assignment
1. OSI Model Matching (2 pts ea.)
Name the layer described.
Layer Description
Offers simplex, half duplex, and full duplex to systems to communicate
Translates data formats and provides coding and conversion functions
Manages device addressing, tracks location of devices, determines best path
Only comes into play when user access to the network is needed
Segments and reassembles data into a data stream
Adds a customized header containing the destination and source address

2. Binary/Hex Conversion (2 pts ea.)
Complete the table.
Decimal value Binary Value Hexadecimal Value
10
15
3
224
255

3. Device Matching (2 pts ea.)
Indicate the device that matches the device type.
Four possible device types – hub, bridge, switch, router

Description Device Type
Uses hardware addresses to filter the network.
Creates one collision domain and one broadcast domain.
Break s up broadcast domains and uses logical address to filter the network.
Breaks up collision domains by creating one large broadcast domain.

4. Connection oriented vs. connectionless (2 pts ea.)

Indicate whether each protocol is connection oriented or connectionless.

UDP
TCP
IP
DHCP
FTP

5. Fill in the blank (2 pts ea.):

• You can run full-duplex Ethernet with just about any device except a ___ ______.
• _________ cable is not susceptible to EMI.
• The three layers in the Cisco hierarchical model are the ________, ________, and ________ layers.
• The term ___________ domain describes a network collection of devices in which one particular device sends a packet to a network segment, forcing every other device

on that same segment to pay attention to it.
• On a ________ domain, a set of all devices on the network segment hear all broadcasts sent on that segment.
• An octet is made up of ___ bits.
• Which type cable would you use to connect a PC to a switch, a crossover or straight-through cable? ___________
• Routers are defined at the _____________ layer of the OSI model.

6. DoD Host-to-Host or Internet layer protocols (2 pts ea.)
