Answer:

This is what we call SQL Injection.

• SQL Injection is when an attacker compromises your database only if it is vulnerable.

• Vulnerability includes leaving an empty ""(value) or forgetting to close anything that could be attacked.

• Ways to prevent injection is to not use string concatenation.

(<em>ex.</em> "hello" + "world")

*  Use parameterized queries.

*   Immediately get rid of any unused code.

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

Can someone please tell me what I’m doing wrong ? Please and it’s due on Thursday!!
liberstina [14]

Answer:

Sure. In Unit test 5, it's looking for 1 instead of 0. You are returning 0 instead of 1.

0 requires 1 digit to express it and should therefore return 1.

In line 6, change the 0 to a 1.
