All code is to be in MIPS assembly language, and only mnemonics with the correet number of operands, based upon the proper design of MIPS assembly are going to be tagged as correct. Briefly explain what "load/store" architecture is. 2) Assume that a byte array called str has been filled with values. Write a code fragment that will read bytes from the array and count the number of bytes until a 0xo (NULL) value is found. Place the final count value in a variable called count that is assumed to be in the .data segment. You do not have to create the data segment; just use the labels as if they have already been created. 1) With respect to instruction execution, explain "delayed branch." 3) Explain why labels are necessary in assembly language programs. 4) 5) MIPS registers to-t9 and so-87 are temporary registers that are available for general purpose use. Explain the difference between registers to-t9 and s0-s7 when the MIPS naming convention is followed
