Consider an assembly language that has a 2-address ISA set. The instructions that are available in this machine are the following: Load b, a Load the value of a to b Add b, a Add the value of a to the value of b and place the result in b Subt b, a Subtract the value of a from the value of b and place the result in b Mult b, a Multiply the values found in a and b and place the result in b Store b, a Store the value of a in b. Output a Display the value of a on the screen Halt Stop the program Write an assembly code to implement the expression on the 2-address machine, and then display the value of d on the screen. Assume that the values of the variables are known. Hence, do not worry about their values in your code. Note that a or b, in the ISA, could be either a register or a variable. Moreover, you can use the temporary registers R1, R2, & R3 in your instructions (which are initially set to zero) to prevent changing the values of the variables (a, b,c) in the expression. Also, note that we do not have a numeric value 4 in the directive part. In accordance with programming language practice, computing the expression should not change the values of its operand.

Data is processed, stored, and transmitted as a series of 1s and 0s. each 1 or 0 is called a(n) . a series of eight 0s and 1s, called a(n) , represents one character—a letter, number, or punctuation mark. data becomes when it is presented in a format that people can understand and use. digital signals are represented by two different , such as +5 volts and +.2 volts. digital data can also take the form of light and dark spots etched onto the surface of a cd or the positive and negative orientation of particles on the surface of a hard disk. data consists of numbers that might be used in arithmetic operations. it can be represented digitally using the number system. data is composed of letters, symbols, and numerals that are not used in arithmetic operations. computers represent this type of data using , ebcdic, unicode, or utf-8. data is quantified using terms such as or kibibyte (1024 bytes), and prefixes such as or mebi (1,048,576), and giga or (1,073,741,824). to reduce file size and transmission times, digital data can be compressed. compression provides the means to compress data and reconstitute it into its original state. compression throws away some of the original data during the compression process. compressed files usually have at the end of the file name and are represented with special icons. these files have to be or unzipped before you can view the data they contain.
