Computer operations refer to mathematical actions for accomplishing any task. In the technologically developed world, computers have been designed with advanced functions. Although, any computer system with a basic version is created with sophisticated processes. The central processing unit (CPU) can perform a billion operations within a second.
The computer systems consist of several processors that perform arithmetic tasks more efficiently. For example, the arithmetic logic unit located within the processor performs mathematical and logical duties.
Basic computer operations
The basic operations of a computer are described in detail.
- Inputs- The inputs are processes for entering information within the computer systems. Information intake is done through image scanning devices, microphones, mouse, graphics tablets, microphones, joystick, light pen, touchpads, etc. This can be referred to as the first process for conducting operation as the computer performs tasks after instructions have been given.
- Arithmetic Logical Unit (ALU)- The ALU performs functions like addition, multiplication, logic, comparison, and division. ALU is equipped with inputs and outputs directly for accessing the controller. The operations include RAM and devices (for input and output).
Both the inputs and outputs are direct through the “bus” system. The information generally includes instructions through words that contain operational codes, operands, and even a formatting code.
- Controlling units- All the computer operations like input, output, storage is performed and managed through central processing units. In addition, it serves the functions of start, stop store, and other parts.
- Outputs- Outputs can be defined as obtaining the result from input information. The devices for showcasing results might include Monitor screens, projector, microfilm, headphones, and others.
- Memory Units- The memory units of the computer store the information and manage instructions.
Logical operations
The logical operation – true operations with a computer are depicted through a special symbol and word that connects with information phrases. The logical process is used when the user tests the relation between true and false representations.
In computers, logical operations become essential because it models information flow through an electrical circuit. Such a logical process within CPU refers to Boolean operations. As per Boolean logic, the circuit elements are also known as logic gates.
Logical operations- True operations
The inputs mentioned below might include two or more pieces of information.
AND- The logical operations like AND will produce a “true:” only if the inputs are not false. In simpler words, if the input is false, the output will also be the same. Therefore, a computer programming language AND operations are depicted as “&&”. For example, Boolean Algebra demonstrated that A and B inputs could be described as AB.
OR – The logical operation – true operations for OR will give an output of true if any of the inputs are also true. Thus, if most of the information is false, the result will be the same. During programming of the computer, OR will be written as ||.
Boolean Algebraic expression will write the OR operation of A and B input as A + B. This expression does not depict addition in arithmetic, as it is an operational programming code.
NOT- It is a reverse operation as the input false will be depicted as true output. During the programming, it will be written as !. Boolean Algebraic the OR code A with overscore.
NAND- The NAND logical operations will give an output true if the input is false. The output will be false if the inputs are true. It uses flash memory which relies on logic gates. Boolean Algebraic will be written as (AB overscore).
NOR- The NOR logical operation will return an output of true if the input is false. Boolean Algebraic expressions (A+B) with overscore. Any logical process creates NOR gates.
XOR- XOR logical operation – true operations. refers to exclusive OR. Thus, the outputs will differ from the outputs. The combination of inputs like true and false will produce an output of true. Boolean Algebraic represent XOR values for A and B inputs as A with an additional symbol in a circle B.
XNOR- The logical operation depicts the false output if the inputs are both true and false. If the inputs are either all true or entirely false, the output will be false. Boolean Algebra XNOR values for A and B inputs will be as A with an additional symbol in a circle B. The expression will be accompanied by an overscore.
Conclusion
Computer operations are divided into five basic ones: input, output, processing, controlling, and storing. Any information given by the user to the computer is input, while processing is making the helpful information, after which it is stored and displayed as output. Computer operations have explained basic operations, logical operations, and logical operations – true operations. The list of seven logical operations is also classified as inputs in true or false, hence producing a single output value.
