Central processing unit.
The correct answer is CPU. CPU is the abbreviation of Central processing unit. CPU is known as the brain of the computer.

What is the order for the steps the compiler uses in translating code?
There are three steps: translation, compilation (assembly), and link-edit. Figure 1 shows these 3 steps.
Which of the following is not an input device test 1?
Monitor
Detailed Solution. Monitor is NOT an Input device. The device which provides any piece of information from a computer into human-readable form is known as the Output device. Monitor, Speakers, Headphones etc are examples of Output devices.
What are two basic categories of variable data types?
There are two major categories of data types in the Java language: primitive types and reference types.
Which of the following is true about the main and secondary memory?
Which of the following are true about main and secondary memory? Main memory is short term memory used by the CPU in processing commands, secondary memory is more permanent and used for storage.
What is computer compiler?
compiler, computer software that translates (compiles) source code written in a high-level language (e.g., C++) into a set of machine-language instructions that can be understood by a digital computer’s CPU. Compilers are very large programs, with error-checking and other abilities.
How does a compiler translate a computer program?
A compiler takes the program code (source code) and converts the source code to a machine language module (called an object file).So, for a compiled language the conversion from source code to machine executable code takes place before the program is run.
Which of the following is storage device?
A correct answer is option (C) Hard disk. A hard disk is a storage device that can store the maximum amount of data.
What are the two kinds of main memory in computer?
Computer memory is of two basic types – Primary memory(RAM and ROM) and Secondary memory (hard drive, CD, etc). Random Access Memory (RAM) is primary-volatile memory and Read Only Memory (ROM) is primary-non-volatile memory.
Which of the following is not a storage device?
A plotter is not a storage device. Explanation: A ‘plotter’ is an external hardware device like a printer used with a computer to ‘print vector graphics’.
What are the 5 main data types?
Data types
- String (or str or text). Used for a combination of any characters that appear on a keyboard, such as letters, numbers and symbols.
- Character (or char). Used for single letters.
- Integer (or int). Used for whole numbers.
- Float (or Real).
- Boolean (or bool).
What are the 3 types of variables?
These changing quantities are called variables. A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled.
What are the 5 types of variables?
There are different types of variables and having their influence differently in a study viz. Independent & dependent variables, Active and attribute variables, Continuous, discrete and categorical variable, Extraneous variables and Demographic variables.
Which of the following is secondary memory?
Disk is a secondary memory device. It cannot be processed directly by the CPU.Secondary memory devices include magnetic disks like hard drives and floppy disks ; optical disks such as CDs and CDROMs ; and magnetic tapes, which were the first forms of secondary memory.
What is main memory and secondary memory?
Computer memory is categorized into primary and secondary memory. While primary memory is the main memory of the computer which is used to store data or information temporarily, whereas secondary memory refers to external storage devices that are used to store data or information permanently.
What is secondary memory in computer?
Secondary memory is also termed as external memory and refers to the various storage media on which a computer can store data and programs. The Secondary storage media can be fixed or removable.
What are types of compiler?
Types of Compiler
- Cross Compilers. They produce an executable machine code for a platform but, this platform is not the one on which the compiler is running.
- Bootstrap Compilers. These compilers are written in a programming language that they have to compile.
- Source to source/transcompiler.
- Decompiler.
What is interpreter and compiler?
Compliers and interpreters are programs that help convert the high level language (Source Code) into machine codes to be understood by the computers.Compiler scans the entire program and translates the whole of it into machine code at once. An interpreter takes very less time to analyze the source code.
Where is compiler in computer?
compilers/assemblers are themselves software, and reside wherever they were installed on the computer. that also implies that you can have as many/few of each as you want.
What type of software controls the internal operations of the computer’s hardware?
System software
System software controls a computer’s internal functioning, chiefly through an operating system, and also controls such peripherals as monitors, printers, and storage devices.
What is Java compiler do?
A Java compiler is a program that takes the text file work of a developer and compiles it into a platform-independent Java file.Generally, Java compilers are run and pointed to a programmer’s code in a text file to produce a class file for use by the Java virtual machine (JVM) on different platforms.
