Dear Wrier it is my solution could oyu please double check this solution and confirm that your solution is correct one? The SLIP frame begins with the character 0xC0, known as the SLIP END character. Bytes in the frame are treated as either control characters or non-control characters. Non-control characters are sent as is, while control characters are replaced by a two-byte sequence. Specifically, 0x7E and 0xDD are non-control characters and are sent as is. 0xDB, 0xC0, and 0x7D are control characters and are replaced by the two-byte sequences 0xDB 0xDC, 0xDB 0xDC, and 0xDB 0xDD, respectively. The byte 0xDC is also a control character and is replaced by the two-byte sequence 0xDB 0xDD. Finally, the frame ends with the SLIP END character (0xC0). The bytes sent on the wire (after framing) are 0xC0 7E DB DD 7E C0 7D DB DC FF DB DD 0xC0. The frame begins with a flag sequence represented by the bit sequence 01111110 and denoted by the value 0x7E. Each byte in the frame undergoes encoding…

3. (a) What is Checksum? Can a checksum be used to detect errors correctly 100% of the time? If we want to be able to detect three-bit errors, what should be the minimum Hamming distance? 3. (b) A sender needs to send the four data items 0x0236, 0×0BCC, 0×03BC, and 0XEEEE. To avoid confusion, Ox is written in the prefix to denote that the data is in Hexadecimal. For example, Ox3456 is 3456 in hexadecimal. Now answer the following: i. Find the checksum at the sender site. li. If the second data item is changed to 0XABCD and the third data item is changed to 0X04BD during transmission, check if there is any error at the receiver site.
