Fichas del conjunto (35)

  1. 1Auxport- standard communication port
    - transmit/receive data one bit at a time
  2. 2TCP- Transmission Control Protocol
    - provides reliable, ordered, and error-checked delivery (segmenting)
  3. 3UDP- User Datagram Protocol
    - connectionless datagram service
    - reduced latency, less reliable
  4. 4OSI modelOSI model
  5. 5ISP- Internet Service Provider
  6. 6DSL- Digital Subscriber Line
    - transmitting digital data over telephone lines
    - mostly ADSL (asymmetric) with 500-800 Mbits broadband
  7. 7Ethernet- used for LANs and MANs (IEEE 802.3)
    - data transfer via cable (twisted pair or fiber optic)
  8. 8Frame- digital data transmission unit
    - data packet in Layer 2 of the OSI model
  9. 9QoS- Quality of Service
    - network delivers services predictable and measurable
  10. 10Circuit-switched networks- if all circuits are busy, a new call cannot be placed
    - finite capacity to create new circuits
    - all parts of single message are transmitted through one circuit
  11. 11Cloud computing- applications can be accessed over the internet through a subscription
  12. 12Passwords for modes and interfaces- VTY interface
    - console interface
    - privileged EXEC mode
  13. 13VTY interface- Virtual teletype = command line interface (CLI)
    - used to facilitate a connection to the daemon via Telnet
  14. 14DHCP- Dynamic Host Configuration Protocol
    - provides automatic IP address configuration to hosts on a network
  15. 15Ping 10.1.1.1- determining if there is connectivity with the destination device
  16. 16Flow control- ensures that data is not send too fast
    - manages the rate of data transmission between two nodes
  17. 17ETS- Engineering Tool Software
  18. 18HTTP-Hypertext Transfer Protocol
    - application protocol for distributed, collaborative, hypermedia information systems
    - foundation of data communication for the www
  19. 19ARP- Address Resolution Protocol
    - used to determine the MAC address of destination host
  20. 20Proprietary protocols- protocols developed by organizations who have control over their definition and operation
  21. 21IEEE 802.11- defines how wireless LANs operate
  22. 22PDU- Protocol Data Unit
    - piece of data at any layer of a network model
  23. 23Packet- PDU at the network layer
  24. 24Frame- PDU at the data link layer
  25. 25Segment- PDU at the transport layer
  26. 26TCP/IP encapsulation process- segments are sent from the transport layer to the internet layer
  27. 27MAC- Media Access Control address
    - unique identifier of network interfaces for communication on the physical network segment
  28. 28NIC- Network Information Center
    - maintains all administrative data of the domain
  29. 29LAN- Local Area Network
    - covering a small local area (home, office)
  30. 30WAN- Wide Area Network
    - covering a broad area (regional, national or international telecommunication networks)
  31. 31MAN- Metropolitan Area Networks
    - covering rooms, buildings, cities
  32. 32Flash memory- electronic non-volatile computer storage
    - can be electronically erased and reprogrammed
  33. 33SSH- Secure Shell
    - cryptographic network protocol
  34. 34NVRAM- Non-Volatile Random-Access Memory
  35. 35Switch- computer networking device that connects devices together
    - uses packet switching to receive, process and forward data to the destination device
