Question

Assumption for the next question: Assume Computers A and B are operating in an older versiorn of Microsoft Windows based network environment which accepts the above subnet mask address. (Hint: Carefully apply the termination criteria of subnet mask algorithm for the next question). 6. Computer A (IP: 200.100.50.25; subnet mask: 255.255.255.193) is on the same subnet as Computer B (IP: 200.100.50.26). 7. IPX/SPX was originally developed by IBM for the mainframe environment. 8. IPv4 addresses are associated with the dotted decimal notation. 9. The Ethernet header at the beginning of a frame usually includes the source and destination IP address information. 10. Vinton Cerf and Bob Kahn are usually referred to as Fathers of TCP/IP or Fathers of the Internet. 11. The 3-way or 3-part handshake (also known as commencement of session management or end-to-end messaging) is a function of IP 12. TCP uses a 4-way or 4-part handshake to complete a transmission session between two computers

Explanation / Answer

6) subnet of A according to A = (200.100.50.25) AND (255.255.255.193)

= (200.100.50.00011001) AND (255.255.255.11000001)

= 200.100.50.00000001 = 200.100.50.1

subnet of B according to A = (200.100.50.26) AND (255.255.255.193)

=  (200.100.50.00011010) AND (255.255.255.11000001)

= 200.100.50.0

Therefore A is on different subnet as computer B.Hence, False.

7.FALSE, IPX/SPX was originally developed by Novell, Inc.

8.TRUE

9.FALSE,The ethernet header at the beginning of a frame includes Preamble and Start of The Frame delimiter.

10.TRUE

11.FALSE, it is a function of TCP.

12.FALSE, TCP uses a 3-way or 3-part handshake to complete transmission session between two computers.
