Assume the contents of memory are shown below. All values are hexadecimal. The table shows four bytes per line; the given address is the starting address of each line.

Each block in the table contains a single byte, with the low and high bytes per line indicated as shown. Each byte has its own address, so the byte at address $092220$ is $01C,$ address $092221$ is OXAD, address $092222$ is $0B5,$ and address $092223$ is $01F.$

You should assume all multi$-$byte values are stored in little$-$endian format.

For each address and amount of data listed, answer the following:

What data are stored at that address?

Would access to the given amount of data at that address be aligned?

If the data represents a signed integer, what is the sign of that value?

For example, given "Address: $0$x$92220,$ Data size: word," your response would be that the word at $092220$ is $01$ FB$5$AD$1$C$,$ the access is aligned, and the data represents a positive integer.

Note: The key points to remember for this problem are:

Little$-$endian data are stored with the least significant byte at the lowest address.

An access is aligned if the address is divisible by the number of bytes being accessed.

In signed formats, the integer is positive if the most significant bit is $0$ and negative if that bit is $1.$
