A queue can be used to do level order traversal of the tree. For each node, first visit the node and then push its children nodes in the FIFO queue. 
printLevelorder(tree)
1) Create an empty queue q
2) temp_node = root /*start from root*/
3) Loop while temp_node is not NULL
a) print temp_node->data.
b) Enqueue temp_node’s children 
(first left then right childr...

1. Let oddPositionBits and evenPositionBits be the two variables that store the value of bits at odd positions and even positions respectively.
2. Set oddPositionBits as the Bitwise AND of N and 0x55555555.
3. Set evenPositionBits as the Bitwise AND of N and 0xAAAAAAAA.
4. Left...

Following are various components/fields of IP packet header
Version: The first IP header field is a 4-bit version indicator. In IPv4, the value of its four bits is set to 0100, which indicates 4 in binary. 
Internet Header Length: Internet header length, shortly known as IHL, is 4 bits in size. It is also called HELEN (Header Length). This IP component is used to show how many 32-bit...

TCP reads data as streams of bytes, and the message is transmitted to segment boundaries. UDP messages contain packets that were sent one by one. It also checks for integrity at the arrival time.
TCP messages make their way across the internet from one computer to another. UDP is not connection-based, so one program can send lots of packets to another.
TCP rearranges data packets in the s...

Source port : 16 Bit number which identifies the Source Port number (Sending Computer's TCP Port).

Destination port : 16 Bit number which identifies the Destination Port number (Receiving Port).

Sequence number : 32 Bit number used for byte level numbering of TCP segments. If you are using TCP, each byte of data is assigned a sequence number. If SYN flag is set (during the initial...
