Operations
In mathematics and computer science, an operation is an event that is carried out to satisfy a given task. Basic operations of a computer system are input, processing, output, storage, and control.
Basic Operators
An operator is a symbol that indicates an operation to be performed. We are familiar with operators in mathematics; operators used in computer programming are—in many ways—similar to mathematical operators.
Division Operator
We all learnt about division—and the division operator—in school. You probably know of both these symbols as representing division:
Modulus Operator
Modulus can be represented either as (mod or modulo) in computing operation. Modulus comes under arithmetic operations. Any number or variable which produces absolute value is modulus functionality. Magnitude of any function is totally changed by modulo operator as it changes even negative value to positive.
Operators
In the realm of programming, operators refer to the symbols that perform some function. They are tasked with instructing the compiler on the type of action that needs to be performed on the values passed as operands. Operators can be used in mathematical formulas and equations. In programming languages like Python, C, and Java, a variety of operators are defined.

Transcribed Image Text:1. Which statement is true about the difference between combinational logic circuits and sequential logic
circuits?
a. If you know the values of the inputs to a combinational circuit, you can tell what the outputs must be, but
a sequential circuit can have different outputs for the same set of input values.
only after generating the inputs.
b. Combinational circuits combine the inputs and the outputs, but sequential circuits combine the outputs
c.
Combinational circuits are more complicated than sequential circuits.
d. Combinational circuits have feedback, but sequential circuits do not.
e.
Combinational circuits are edge triggered, but sequential circuits are level-sensitive.
2. Which instruction format does BEQ use?
a. B-Format.
b. I-Format.
C. R-Format.
d. J-Format.
e. M-Format.
3. Why is it important to use flip-flops instead of latches to construct a Finite State Machine?
a. Flip-flops will never change state more than once per clock cycle, which is essential for designs like Finite
State Machines where the outputs of the machine feed back into the inputs.
Flip-flops are the only way to provide the speed necessary for reliable Finite State Machine operation.
b.
c.
d.
e.
The reduced speed of flip-flops is necessary to ensure reliable Finite State Machine operation.
Flip-flops cost less than latches, so you have to use flip-flops to obtain the most economical
implementation possible.
e. Flip-flops use less power than latches, so their use is important for optimizing battery life.
4. What are the inputs to the adder that computes the Branch Target Address?
a. 3 and 5.
Stroj Josimo
Stam
b.
The outputs of data memory and the ALU.
c.
The two outputs from the register file.
d. The output from the PC+4 adder and the immediate field of the instruction multiplied by 4 and sign
extended.
The PC and RegDst.
