Which of the following are legal lines of Java code?
1. int w = (int)888.8;2. byte x = (byte)100L;3. long y = (byte)100;4. byte z = (byte)100L;
Suppose you are compiling on a machine with 1-byte chars, 2-byte shorts, 4-byte ints, and 8-byte doubles, and with alignment rules that require the address of every primitive data element to be an integer multiple of the element's size. Suppose further that the compiler is not permitted to reorder fields: padding is used to ensure alignment. How much space will be consumed by the following array? struct { short s; char c; short t; char d; double r; int i; } A[10]; /*10-element array of structs*/
Given below are two statements:  Statement I: Minimum number of bits required to store any 3-digit decimal number is 10.  Statement II: The data in a digital computer is stored in terms of bits/ bytes where one Peta Byte is equal to 250 bits.

How many redundant bits are added in block codes for k information bits and n code bits?
Which of the following codes uses a number of parity bits located at certain positions in the codeword and uses the relations between redundancy bits and the data bits?
A message consisting of 2400 bits is to be passed over the Internet. The message is passed to the transport layer which appends a 150-bit header, followed by the network layer which uses a 120-bit header. Network layer packets are transmitted via two networks, each of which uses a 26-bit header. The destination network only accepts up to 900 bits long. The number of bits, including headers delivered to the destination network, is
