MAC vs IP

Only want to make the archive from a small experiment. Not want to break that more research first, if there is a conflict with this. Because I am only trying to record a recall.

In this experiment, has been prepared 2 computer (real) with the Windows XP SP2 Operating System, IP 10.12.3.40 and 10.12.3.53, to conduct an experiment on the MAC and IP.
Inside the Computer 1 has been activated Microsoft Virtual PC 2007 with Windows XP SP2 Operating System (Computer 1a) and VMWare with the Linux Backtrack Operating System (computer 1b). Can be understood, that in this experiment, there are 4 computer that is ready for use.

Details of equipment:

Computers 1
MAC 00-0F-FE-95-0F-5F (G-Pro Computer)
IP 10.12.3.40

Computers 1a
MAC 00-03-FF-97-0F-5F (Connectix)
IP 10.12.3.39

Computer 1b
MAC 00-0C-29-F7-AE-A1 (VMware)
IP 10.12.3.38

Computers 2 (borrowed from Soni Firyadi)
MAC 00-0F-FE-95-12-7B (G-Pro Computer)
IP 10.12.3.53


1. MAC Computers 1a reconcile with the MAC computer 2, successfull.
Changing the ending of the IP 39 to 53, after the MAC on. Success, the connection does not interfere out, there is no conflict.
Computer 1a and computer 2, not experienced any disruption to the network, both for the local area network or intranet with a pass through the router.


2. Computer 1b use Backtrack with IP 38, IP reconcile with Computer 2 to 53, without equates the MAC.
Computer 1b success change to IP 38, without requiring the replacement of the MAC. Computer 2 while on the notification system appear error (IP Conflict)

Then, the MAC Computers 1b reconcile with Computer 2, which is the IP conflict.
After the same MAC, the Computers 2 and 1b same does not have a problem with the network connection.

3. MAC Computers 1a reconcile with the Computer 1 (parent), successfull.
IP Computers 1a (39) reconcile with the Computer 1 (40), there is no conflict. What is happening is not a conflict? Not fact.
Computer 1a have a problem with the network connection, although there is no message from Windows saying that the IP conflict occurs.
Computers 1a is not only not able to pass through the router, but also not able to pass through an Ethernet Card, which is owned by the Computer 1.

4. Computers 1b that use the IP 38, analogous to the Computer 1 (40). Computer 1b, streamlined access to existing web outside the office, while Windows is on the Computer 1 to give warning that the IP conflict. Computer 1 is not able to go everywhere.
MAC of computer 1b (40), reconcile with the MAC of computers 1 (40 - IP Conflict). Computer 1b, can still connect to the web outside the office, while Computer 1 still can not connect with other computers even though there is no conflict IP messages from Windows.
Ethernet Card on Computer 1, that use Windows XP SP2, can be penetrated even closed by Backtrack.

Hopefully with this little experiment here is archived here, I can continue to remember about this simple experiment and discard little bit stupid.

Bit and Byte

Two words that are very close to the world of computer networking, similar but very different in meaning, not even a little from the people who work every day with the world's computers can not distinguish the two. For those who are not too familiar with computer networking, may also often find the words to the ad provider of internet services that are doing the promo. I'm a very public computer networking in the world, is also the first do not understand the difference in these two words. I think that there is no difference between the two, I think when there is a write small letters or large, it is an error.
Until the time I read a book written by S'to, entitled Wireless Kung Fu published by Jasakom, then I can slightly understand the difference from the second word. In fact, the differences between them have a very basic and very wrong when we equate the function of both, because both are very different significantly. In the book, S'to explains, based on the experience of one of his colleagues who complained about the speed of Speedy, which has a speed of up to advertise with 384Kbps, while he obtained based on the data indicated by downloader from the browser only about 29.6KB/sec.
Imagine much of the difference between the number 384 with 29.6, what actually happened? Is Speedy is doing against consumer fraud? There is a one-count with the count done by the downloader browser?
No need to search for errors on the above issues. Writing letters large and small that is done, it has a different meaning, is not an error.
Meaning Kbps in the letter b indicates bits of the units, meaning Kbps indicates Kilo bit per second. Meanwhile, in Kbps B shows bytes, can be defined Kbps means Kilo Bytes per second. So the core issue here is the actual terms of bits and bytes, two words that are very similar.
In the book, S'to shows that the unit byte is a unit to 8 bits, or in other words, can be 1 byte same with 8 bits. It seems there are already starting point of light between the second word. So it can be said that in Speedy ads that claim is the maximum download speed of 384Kbps is the same with 48KBps (384 / 8). Speed like that of course if the situation occurs in a very perfect, with no interference at all. So when a friend from Sto gain speed 29.6KB / s, which is shown by the downloader from the browser, it is very normal and can be said is good enough.
Thank you for S'to have to give enlightenment on this issue, one final footle again successfully reduced my ignorance of the exchequer.
