Complete Question:
Remember that in the CSMA/CD protocol, after a collision, the adapter pauses for K. 512 bit times, where K is randomly chosen. a. For the first collision, if K=100, what is the waiting duration before sensing the channel again for a 1 Mbps broadcast channel? And for a 10 Mbps broadcast channel?
Answer:
a) 51.2 msec. b) 5.12 msec
Explanation:
With K set at 100, the duration the adapter must wait after detecting a collision is calculated using the following formula:
The bit time is determined by the inverse of the channel's bandwidth, expressed in bits per second. Therefore, for the instances mentioned in the question, we get:
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

Clarification:
Examine the SQL statement shown below:
SELECT c.CustomerName, e.LastName, s.ShipperName, p.ProductName, o.Quantity, od.OrderDate
FROM
Customers c, Employees e, Shippers s, Orders o, OrderDetails od, Products p
WHERE c.customerID = o.customerID AND
e.employeeID = o.employeeID AND
o.orderID = od.orderID AND
od.shipperID = s.shipperID AND
od.productID = p.productID;
I think it's text wrapping! I hope this assists you.
The question is incomplete, as it lacks a diagram of the topology and Router R1's table. I assume the user has access to both the topology and routing information.
The configuration below will assist in resolving the ACL issue:
Hosts within the 172.16.0.0/16 network should have unrestricted access to Server1, Server2, and Server3, which is currently not the case since L1 is unable to connect to Server2 or Server3.
The suggested configuration on Cisco Router R1 will rectify the ACL issues.
