Memorise Flashcards
VLAN (virtual local area network) benefits
Reduces to broadcast Less cost equipment. Controlled environment
Telnet vs SSH
Telnet access CLI over network SSH- more security
APIPA
Computor cannot obtain IP address from server
Ethernet (LAN)
Ports are found on end user devices , switch devices , network devices
IPv4
32 bits , 4 parts , 3 classes
Classes of IP address. A,B,C private
A= large companies 0-126. 10.0.0.0 10.255.255.255 B= medium (128-191) 172.16.0.0 172.255.255.255. C= small. (192-223) 192.168.0.0 192.168.255.255. D- 224-239 multicast address
Disk cleanup
Delete the unwanted files
IMAP
Message access protocols works with emails copy on server (backup) and send it to packet
SMTP
Simple mail transfer protocol the client sends email to server
Pop
No copy
UDP vs TCP
Unreliable and TCP reliable
BOOTTP
Assign IP address manually and helps computor to find a domain as it has no hard disk
DNS
Maps address fully qualified domain name
Trap messages
Event occurs causes device to send SMNP trap such as power outrage and security breaches
Address
Logical is network later each packet and give IP address. MAC - switch IP config- in ICMP
Default router vs router
Sparks from end to another Router - shows all commands
OSPF
Faster realisable robust flexible Quick but slower than RIP listed routing protocol Uses DJKSTRA Agorithum to construct shortest path of tree and build routing table and supports IPV6
