How is a 16-bit memory address divided into tag, line number, and byte number? b. Assume that a direct mapped cache consisting of 32 lines is used with this machine. Consider a machine with a byte addressable main memory of 216 bytes and block size of 8 bytes. Since an IPv4 header may contain a variable number of options, this field specifies the size of the header (this also coincides with the offset to the data). Header length or Internet Header Length (IHL) :-The second field (4 bits) is the Internet Header Length (IHL) telling the number of 32-bit words in the header.For example, 64-bit versions of Windows require that all device drivers be signed. Windows 10 64-bit includes a few additional security features that aren’t available in Windows 10 32-bit.
