how to change mac address of a system ?

Answer

MAC - Media Access Control
- Also known as physical address (cannot be changed
convetionally)
- (IP Address - logical address - can be changed)
- contains 48 bits or 6 bytes
- Example 00-13-02-C0-14-13
FF-FF-FF-FF-FF-FF - ARP broadcast
Each F (in this case) is an Hexa decimal number is
called "Nibble"
The first 3 bytes (00-13-02) is vendor specific
The second 3 bytes (C0-14-13) - is allocated to the
vendor by the IEEE
- MAC address can be used for security (in Switches)
- MAC address security is extra protection in Wireless
Networks
- MAC spoofing (changing the MAC address) can be used
or both for good and bad purposes (Not recommended -
may create issues in your network)
- Use "ipconfig /all" or "net config rdr" in command
prompt
- to change MAC (NIC properties / advanced TAB /
Locally administered Address / in XP / VISTA)

Question { Google, 6334 }

I would like to submit the following question I was asked
recently during my technical interview at Google.
I'm rephrasing the question to make it clear for everyone
to understand:

- You are going on a one-way flight trip that includes
billions of layovers.
- You have 1 ticket for each part of your trip (i.e: if
your trip is from city A to city C with a layover in city
B, then you will have 1 flight ticket from city A to city
B, and 1 flight ticket from city B to city C.
- Each layover is unique. You are not stopping twice in the
same city.
- You forgot the original departure city.
- You forgot the final destination city.
- All the tickets you have are randomly sorted.

Question are:
- Design an algorithm to reconstruct your trip with minimum
complexity.
- How would you improve your algorithm.

Example:
- randomly sorted:
New York->London
San Francisco-> Hong Kong
Paris->New York
London->San Francisco

- sorted:
Paris->New York
New York->London
London->San Francisco
San Francisco-> Hong Kong

Answer

1) Assuming the data in 2 dim array. (2 Columns: FROM
destination & TO destination)
2) Sort the array (any standard sorting logic) using column
1 i.e. FROM destination.
3) Take "TO" destination value of row 1 and use binary
search to search its match in "FROM" destination column
from row 2 to n
If match found, adjust that row as row 2. (Swap
pointers in place of physical data)
Take "TO" destination value of row 2 and
use binary search to search its match in "FROM" destination
column from row 3 to n
continue this logic till as long as a match
is found.

if match not found.
Resort the remaining unadjusted rows
using "TO destination" column.
Take "From" destination value of
row 1 and use binary search to search its match in "To"
column in all unadjusted rows.
Match must be found otherwise data
incorrect. adjust that row as row -1. (Swap pointers in
place of physical data)
Continue this till end of the
array.

Now you have the sorted list.


I am sure there can better ways to achieve the same.
