CISSP - Switching_Remote_Access_Ethernet_and_Token_Ring

two technologies used for quick transmission of data across networks

______ creates a physical circuit path between the sender and the
receiver devices on a WAN.

connections for a single transmission, they provide uniform transmission with no loss or interference.

_____ network fragments large messages, and encapsulates them into small packets having
frame check sequence numbers

these network technologies do not establish a connection

they make optimal utilization
of network resources and transmit data packets using any available circuit path on the network

there are five different technologies used by packet switched networks

- is a high speed networking technology that is connectionoriented
- uses a cell-switching method
- transmits data in fixed sized cells of 53 bytes

- was developed as an upgrade from X.25 and LAPB
- functions at the physical and
data link layers of the OSI model.
- does not unpack frames at each node

- was developed to be used with X.25
- can retransmit, exchange, and acknowledge frames
- ensures that the frames are correctly
sequenced and error free

- uses carrier switches to enable computers on different public networks
to communicate
- defines communication between data terminal equipment (DTE) and the data
circuit-terminating equipment (DCE) devices

- is a high speed, datagram-based WAN technology that is used for communication over public data networks
- connectionless protocol

Different remote access protocols are used to authenticate users and establish a reliable connection

- designed to work on serial ports and dial-up connections
- encapsulates IP packets by appending special framing characters to them

- designed as a successor of SLIP
- enables systems to communicate through a serial link connection

- enables user authentication over PPP lines
- process is referred to as a two way hand shake

- is a PPP authentication protocol that
facilitates remote logon between a client and a server or between a web browser and a web server

- is not an authentication mechanism
- supports multiple authentication techniques, such as Kerberos, one time passwords, token cards, public key authentication, biometrics, and smart cards

what do these have in common:
• 10Base2
• 10Base5
• 10BaseT
• Fast Ethernet
• Gigabit Ethernet

- known as Thinnet
- maximum cable length of 185 meters and provides transmission rates of 10 Mbps

- is commonly implemented
using a star topology,
- operates at 10 Mbps speed, and
- uses RJ-45 connectors to connect the
cables to the computers

- called Thicknet
- maximum cable length of 500 meters
- data transmission speed of 10 Mbps

- referred to as 100 Base-T
- data transfer rates of 100 Mbps
- follows the traditional CSMA/CD access method

- supports data transfer rates of 1Gbps
- primarily used as the backbone in
large enterprise networks
