What performs arithmetic and logical operations in a computer?
An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. It represents the fundamental building block of the central processing unit (CPU) of a computer. Modern CPUs contain very powerful and complex ALUs. In addition to ALUs, modern CPUs contain a control unit (CU).

What is Alu in computer?
In computer science: Architecture and organization. …of a control unit, an arithmetic logic unit (ALU), a memory unit, and input/output (I/O) controllers. The ALU performs simple addition, subtraction, multiplication, division, and logic operations, such as OR and AND.
What is the function of Cu and Alu?
An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. It represents the fundamental building block of the central processing unit (CPU) of a computer. Modern CPUs contain very powerful and complex ALUs. In addition to ALUs, modern CPUs contain a control unit (CU) .
What is difference between CU and ALU?
It is popularly known as CPU. It is used to process instructions. The principal component of the CPU is the Arithmetic Logic Unit and Control Unit. In this article, we will learn what is the main difference between ALU and CU….Related Articles.

What are the types of ALU?
An ALU consists of three types of functional parts: stor- age registers, operations logic, and sequencing logic, as shown in Fig. 1.
What is Alu short answer?
Stands for “Arithmetic Logic Unit.” An ALU is an integrated circuit within a CPU or GPU that performs arithmetic and logic operations. However, ALUs typically do not perform division operations, since the result may be a fraction, or a “floating point” number.
What is Alu with diagram?
The heart of every computer is an Arithmetic Logic Unit (ALU). This is the part of the computer which performs arithmetic operations on numbers, e.g. addition, subtraction, etc. The ALU will generate an 8-bit result (result), a one bit carry (C), and a one bit zero-bit (Z).
What are the components of ALU?
A typical ALU consists of three types of functional parts: storage registers, operations logic, and sequencing logic.
What is the difference between CPU and ALU?
The main difference between CPU and ALU is that the CPU is an electronic circuit that handles instructions to operate the computer while the ALU is a subsystem of the CPU that performs arithmetic and logical operations. The most essential component of a computer is the CPU. CPU is also known as the processor.
What is the difference between internal and external memories?
Internal memory is normally associated with RAM (or random access memory) and is also known as main memory. It’s typically smaller in size but has faster access times. External memory, also known as secondary memory, is separate from main memory.
What do you know about CPU and ALU?
Answer. Difference Between ALU and CPU is that arithmetic logic unit (ALU), another component of the processor, performs arithmetic, comparison, and other operations. While Processor also central processing unit (CPU), interprets and carries out the basic instructions that operate a computer.
What is the full name of ALU?
arithmetic logic unit
What is the full form of DOS?
Abstract. DOS stands for Disk Operating System and is the computer program no personal computer can do without. It exists in two forms. The one supplied for IBM Personal Computers is known as PC-DOS. All other compatible personal computers use MS-DOS.
What is a CU?
The control unit (CU) is a component of a computer’s central processing unit (CPU) that directs the operation of the processor. It directs the flow of data between the CPU and the other devices. John von Neumann included the control unit as part of the von Neumann architecture.
What is the full form of CLI?
C:\>npm install mysoftware. CLI stands for: Command Line Interface. Command Line Interpreter. Command Line Input.
What does CLI stand for in ICT?
command language interpreter
What is the full form of Linux?
The full form of LINUX isLovable Intellect Not Using XP. Linux was built by and named after Linus Torvalds. Linux is an open-source operating system for servers, computers, mainframes, mobile systems, and embedded systems.
What are commands?
Commands are a type of sentence in which someone is being told to do something. There are three other sentence types: questions, exclamations and statements. Command sentences usually, but not always, start with an imperative (bossy) verb because they tell someone to do something.
How many types of commands are there?
four types
What is the use of commands?
In computers, a command is a specific order from a user to the computer’s operating system or to an application to perform a service, such as “Show me all my files” or “Run this program for me.” Operating systems such as DOS that do not have a graphical user interface (GUI) offer a simple command line interface in …
Which is a list of available commands?
control keys
What are the main menu commands?

What is command line flag?
Command-line flags are a common way to specify options for command-line programs. For example, in wc -l the -l is a command-line flag. It’s also possible to declare an option that uses an existing var declared elsewhere in the program. Note that we need to pass in a pointer to the flag declaration function.
What is Flag in coding?
In computer science, a flag is a value that acts as a signal for a function or process. The value of the flag is used to determine the next step of a program. Flags are often binary flags, which contain a boolean value (true or false).
What is a flag switch?
Feature flags (also known as feature toggles or feature switches) are a software development technique that turns certain functionality on and off during runtime, without deploying new code. This allows for better control and more experimentation over the full lifecycle of features.
How do you use a flag?
Example 1 : Check if an array has any even number. There is one even number in the array. We initialize a flag variable as false, then traverse the array. As soon as we find an even element, we set flag as true and break the loop. Finally we return flag.
What is the difference between an argument and an option?
Argument 0 is (normally) the command name, argument 1, the first element following the command, and so on. These arguments are sometimes called positional parameters. An option is a documented type of argument modifying the behavior of a command, e.g. -l commonly means “long”, -v verbose.
What are Linux flags?
Flags. Flags are a way to set options and pass in arguments to the commands you run. You should read the documentation of each command to know what flags are available. For example, running ls with the -l flag ( ls -l ) will include more information in the result and change the format of what is returned.
