NETWORKING Flashcards
pc network for sharing info, is the language/set of rules to follow or speak, all pc’s us this suit
protocols
TCP/IP
TRANSMISSION CONTROL PROTOCOL/ INTERNET PROTOCOL
USED TO SHARE FILES IN LAN/WAN, USES PORT 20, 21
FTP(FILE TRANSFER PROTOCOL)
USES PUSH/PULL, USES PORT 69(NON-ENCRYPTED) DOESNT SUPPORT AUTHENTICATION
TFTP(TRIVIAL FILE TRANSFER PROTOCOL)
ADD ENCRYPTION TO FTP, IS A EXTENSION OF SSH, USES PORT 22 SAME AS SSH
SFTP(SECURE FILE TRANSFER PROTOCOL)
OUT GOING MAIL TO SERVER, PORT 25
SMPT(SIMPLE MAIL TRANSFER PROTOCOL)
DOWNLOADS INCOMING MAIL TO SEVER, PORT 110
POP3(POST OFFICE PROTOCOL)
SYNC MAIL COMING TO SERVER, KEEPS MAIL ON DEVICE AND SERVER, PORT 143
IMAP(INTERNET MESSAGE ACCESS PROTOCOL)
DO NOT USE, PROVIDES REMOTE COMMAND LINE ACCESS TO INTERACT WITH SERVER, PORT 23
TELNET
PROVIDES ENCRYPTED REMOTE LINE ACCESS TO INTERACT WITH SERVER, V2 ADDED SFTP/SCP SUPPORT, PORT 22
SSH(SECURED SHELL)
PROVIDES NAME TO IP ADDRESS RESOLUTION FROM HOST,PORT 53
DNS(DOMAIN NAME SERVICE)
VARIOUS CONFIGS TO CLIENT IP NETWORK VIA BROADCAST, PORT 67(SERVER) PORT 68(CLIENT)
DHCP(DYNAMIC HOST CONFIGURATION PROTOCOL)
TRANSMIT WEB PAGES, PORT 80
HTTP(hyper text transfer protocol)
TRASNSMITS WEB PAGES SECURLEY USING SSL OR TLS, PORT 443
HTTPS9HYPER TEXT TRANFER PROTOCOL SECURE)
PROVIDES VERIOUS NETOWRK COMMAND FEATURES IN WINDOWS NETWORK,USED IN WINDOWS BE FOR IP NETWORKING
NETBIOS(NETWORK BASIC INPUT/OUTPUT SYSTEM)
QUERY/CONFIG/MONITOR BURST IN LAN, V3 ADDES ENCRYPTION, PORT 161/162
SNMP(SIMPLE NETWORK MANAGMENT PROTOCOLS)
DOMAIN-BASED NETWORKING ENVIORMENT TO FACILITATE SYSTEM/USER MANAGMENT, PORT 389
LDAP(LIGHTWEIGHT DIRECTORY ACCESS PROTOCOL)
FILE SHARE/ NETWORK BROWSING/ PRINTING SERVER, COMMON ON WINDOWS SERVER, SUPPORTS LINUX, MAC OS AND OTHERS
SMB(SERVER MESSAGE BLOCK)
OPEN IMPLEMENTATION USED ON LINUX/MACOS, PORT 445
CIFS(COMMON INTERNET FILE SYSTEM)
USED TO SECURLEY AND REMOTLEY ACCESS WINDOWS DESKTOP, PORT 3389
RDP(REMOTE DESKTOP PROTOCOL)
RELIABLE, CONNECTION ORIENTED, VIRTUAL CIRCUT, SEQUENCED ACKNOWLEDGMENT, 24-60 BYTES(HIGH OVERHEAD)
TCP(TRANSMISSION CONTROL PROTOCOL)
UNRELIABLES, CONNECTIONLESS, NO ACKNOWLEDGMENT
UDP(USER DATA PROTOCOL)
CONNECTS DEVICES TO NETWORK, UNIQUE 48 BUT MAC ADDRESS,
NIC(NETWORK INTERFACE CARD)
USED TO MANAGE AND CONNECT WIRED COMMS IN A LAN, USES CSMA/CD TO MANAGE COLLISIONS, SLOWS DOWN NETWORK SPEEDS
HUB
MANAGES COMMS ON A LAN, FORWARD FRAMS BASED ON MAC ADDRESS, PROVIDES PORT SECURITRY, DHCP SNOOPING, AND DYNAMIC ARP INSPECTIONS, WHEN INCOMING DATA GOES TO THE SWITCH IT KNOWS WHERE TO SEND THE IT, DOES NOIT REPEAT DATA
SWITCH
CONNECTS DEIFFERENT BRAODCAST DOMAINS TO EACH OTHER, LAN->WAN, FORWARDS TRAFFIC BASED ON IP ADDRESS PACKETS, DOES NOT USE MAC ADDRESS
ROUTER
SECURES DEVICE, STOPS UNAUTHERIZED ACCESS TOP LAN FROM WAN, DMZ IS WHERE THE FIREWALL DOES NOT PROTECT SO IT CAN CONNECT TO THE INTERNET, PORTS1-1023 COMMON/ PORTS 1024-48/49,000 REGISTERED PORTS(MANUFACTURE ONLY)
FIREWALL
PROVIDES/MANAGES WIRELESS COMMS INA LAN, USES RF TO TRANSMIT HOST DATA
AP(ACCESS POINT)
MULTIFUNCTIONING, INCLUDES WIRELESS, SWITCH AND FIREWALL AND DHCP
SOHO ROUTER(SMALL OFFICE/ HOME OFFICE)
ALLOWS YOU TO POWER DEVICES OVER ETHERNET, SWITCH NEEDED TO POWER MULTIPLE DEVICES
POE(POWER OVER ETHERNET)
INTERNET THROUGH TELEPHONE LINES, BRAODCAST HAS A LOT OF SIGNLAS ON A LINE, NEEDS A FILTER OR IT WILL MESS WITH DATA/PHONE INTEGRATY
DSL(DIGITAL SUBSCRIBER LINE)
CONVERTS OPTICAL SIGNALS THROUGH FIBER INTO SEPERATE SIGNALS, VOICE/TV/DATA
ONT(OPTICAL NETWORK TERMINAL)
ENABLES DYNAMIC, PROGRAMMATICALLY EFFIECNT NETWORK CONFIG TO IMPROVE NETWORK PERFORMANCE AND MONITORING, USES CONTROLLER TO MANAGE NETWORK TRAFFIC, FORWARDS NETWORK PACKETS(DATA PLANE) FROM ROUTING PROCESS(CONTROL PLANE)
SDN(SOFTWARE DEFINED NETWORKING)
LONMG RANGE COMMS, BETTER FOR PASSING THROUGH BARRIERS,SLOWER DATA RATE, NON-OVERLAPPING CHANNELS 1/6/11 OFFER BEST CHANCE OF MINIMIZING INTERFERANCE
2.4GHz
SHORT RANGE, BED PENITRATION, FASTER SPEEDS, 45 CHANNELS AND 24 NON-OVERLAPPING, 20MHz USES 36/40/44/48/149/153/157/161/165, 40MHz USES 38/46/151/159
