Which is true about SSH and Telnet?
MaRussiya [10]

Answer:

Data is encrypted on SSH

Explanation:

Telnet and SSH both are the networking protocols. These protocol are used for the security of data. In telnet data is sent over the link without any encryption. That is the reason, in telnet protocol data is less secure.

In SSH (Security Shell) protocol data has been encrypted before transmission. The encryption of data make it more secure between transmitter and receiver.

So the true statement is that, SSH has data encryption.

julia-pushkina [17]

Complete Question:

Recall that with the CSMA/CD protocol, the adapter waits K. 512 bit times after a collision, where K is drawn randomly. a. For first collision, if K=100, how long does the adapter wait until sensing the channel again for a 1 Mbps broadcast channel? For a 10 Mbps broadcast channel?

Answer:

a) 51.2 msec.  b) 5.12 msec

Explanation:

If K=100, the time that the adapter must wait until sensing a channel after detecting a first collision, is given by the following expression:

  • Tw = K*512* bit time

The bit time, is just the inverse of the channel bandwidh, expressed in bits per second, so for the two instances posed by the question, we have:

a) BW  = 1 Mbps = 10⁶ bps

⇒ Tw = 100*512*(1/10⁶) bps = 51.2*10⁻³ sec. = 51.2 msec

b) BW = 10 Mbps = 10⁷ bps

⇒ Tw = 100*512*(1/10⁷) bps = 5.12*10⁻³ sec. = 5.12 msec
