NT1210 Final Exam Review
Final Exam Review
Using Table 10-1, review default port numbers used commonly with TCP and UDP purposes
HTTP TCP Port 80 – used by web browsers and web servers
Telnet TCP Port 23 – used for terminal emulation
SSH TCP Port 22 – used for secure terminal emulation
FTP TCP Port 20, 21 – used for file transfer
DNS UDP Port 53 – used for name resolution
SMTP TCP Port 25 – used to send and receive email
POP3 TCP Port 110 – another email protocol
IMAP TCP Port 143 – another email protocol
SSL TCP Port 443 – used to encrypt data for secure transactions
SNMP UDP Port 161, 162 – used to manage TCP/IP networks
TCP – Transmission Control Protocol
UDP – User Datagram Protocol
IPv4 32 bits, IPv6 128 bits
Bring sub-netting sheet for use during exam
Byte = 8 bits
Truth Table 0 AND 0 = False (0) / 1 AND 0 False (0) / 1 AND 1 True (1)
Truth Table
Parentheses in mathematical equations = do that FIRST
Node on a network = device
Which LAN topology has single point of failure = Star
Which WAN topology has single point of failure = Hub and Spoke
Recognize parts of web address that are the protocol, web page and domain name
Basic to every networking standard = agreed upon set of rules for communication, standard means they are documented
TCP divided into layers for better troubleshooting
OSI layer responsible for encryption and compression = Presentation Layer (Layer 6)
Network encoding scheme = set of rules that define how to change the pattern of the waveforms of energy to represent binary 0’s and 1’s (how it is transmitted and interpreted by both nodes)
What causes full duplex to transmit and receive simultaneously = 2 pairs of wires, 1 pair for transmit, one for receive
Max distance for UTP = 100 meters
Standard for Ethernet 802.3
Standard for Wireless 802.11
Ethernet Bit Rate – speed of cables used in the Ethernet network
What pairs of UTP are used for transmit and receive = 3/6 receive, ½ transmit
Site Survey to determine where AP should be placed
