      A bit is the smallest unit of storage represented by 0 or 1. A byte is typically 8 bits. C character data type requires one byte of storage. A file is a sequence of bytes. A size of the file is the number of bytes within the file. Although all files are a sequence of bytes,m files can be regarded as text files or binary files.

      ter. The result for the low byte is XORed to the content of CRC_LOW. The results are stored back in CRC_LOW. The next step is that the content from CRC_HIGH is shifted into CRC_BUFF and the content from CRC_LOW is shifted into the register, CRC_HIGH. Then the register, CRC_LOW, is loaded with the new data byte. This process repeats for all data ...

      conceptually split the main memory into 2n-byte chunks too. To determine the block address of a byte address i, you can do the integer division i / 2n Our example has two-byte cache blocks, so we can think of a 16-byte main memory as an “8-block” main memory instead. For instance, memory addresses 12 and 13

      For this assignment, you will use the struct mechanism in C to implement a data type that represents an array of bytes. This data structure could be used kind of like a base class for a string type, or a more general dynamic array type. An array of bytes can be modeled using the C struct: // Bytes type, represents an array of byte-sized values.
