Explanation / Answer
1) The four-byte sequence 0x7B 0x8A 0x2F 0x92 stored in consecutive memory cells in a little-endian architecture represents ___________ (decimal) when interpreted as a 32-bit signed integer.
Little Ednian means Least significant bit will be stored in lower addess , If the address starts from 1000
1000-->0x92
1001-->0x2F
1002-->0x8A
1003-->0x7B
1001 0010 0010 1111 1000 1010 0111 1011 => 2452589179 in decimal
2. The four-byte sequence 0xC1 0xAC 0xDC 0x4B stored in consecutive memory cells in a little-endian architecture represents ___________ (decimal) when interpreted as a 32-bit signed integer.
1000-->0x4B
1001-->0xDC
1002-->0xAC
1003-->0xC1
0100 1011 1101 1100 1010 1100 1100 0001 => 1272753345 in decimal
3. The four-byte sequence 0xC8 0x85 0xFF 0x21 stored in consecutive memory cells in a little-endian architecture represents ___________ (decimal) when interpreted as a 32-bit signed integer.
1000-->0x21
1001-->0xFF
1002-->0x85
1003-->0xC8
=> 570394056 in decimal
3. The four-byte sequence 0xAA 0x8B 0x8C 0x4B stored in consecutive memory cells in a little-endian architecture represents ___________ (decimal) when interpreted as a 32-bit signed integer.
1000-->0x4b
1001-->0x8C
1002-->0x8B
1003-->0xAA
01001011100011001000101110101010 IN Binary => 1267501994 in decimal
