Ans- the computer is a programmable finite state machine that can perform precise arithmetic and logic operations.
What is the software of a computer?Ans- A list of instructions can be submitted to the computer in the form of a program. A collection of related programs is referred to as the software.
What is application software?Ans- Application software (app for short) is a program or group of programs designed for end-users. Examples of an application include a word processor, a spreadsheet, an accounting application, a web browser etc.
What is system software?Ans- System software is software designed to provide a platform for other software. Examples of system software include operating systems like macOS, GNU/Linux , Android and Microsoft Windows, computational science software, game engines, industrial automation, and software as a service applications.
What is Algorithm?Ans- In mathematics and computer science, an algorithm (/ˈælɡərɪðəm/ (About this soundlisten)) is a finite sequence of well-defined, computer-implementable instructions, typically to solve a class of problems or to perform a computation. Algorithms are always unambiguous and are used as specifications for performing calculations, data processing, automated reasoning, and other tasks.
What is web browser?Ans- A web browser (commonly referred to as a browser) is a software application for accessing information on the World Wide Web. When a user requests a web page from a particular website, the web browser retrieves the necessary content from a web server and then displays the page on the user's device.
What is the hardware of a computer?Ans- The physical circuity and components are known as the hardware of the computer.
What are the hardware types of a computer?Ans- Ans the hardware can be categorized into five blocks. for more details about input units, visit my article computer hardware basics.
- Input Units
- ALU
- Control Unit
- Memory
- Output Unit
Ans- The input unit is the device used to enter data and constructions into the computer. Some inputs devices of a computer are keyboard, mouse, joystick, light pen, etc.
What is Arithmetic Logic Unit?Ans- Arithmetic Logic Unit(ALU), in computing, an arithmetic logic unit is a combinational digital circuit that performs arithmetic and bitwise operations on integer binary numbers. This is in contrast to a floating-point unit, which operates on floating-point numbers. The arithmetic operations include addition, subtraction, multiplication, and division. The logical operations include boolean functions such as AND, OR, and NOT.
What is Control Unit?Ans- The control unit coordinates the activities of the various components of a computer. The ALU and control unit together comprise the central processing unit(CPU). The CPU control unit is called microprocessors. The speed of a computer depends on the clock frequency of the microprocessor.
What is memory of computer?Ans- The computer’s memory is constructed out of semiconducting material and stores information in binary form. Binary information is composed of two symbols the is 0 and 1 called binary digits(bits).
What is output units of computer?Ans- The information generated by computer is displayed uing an output device. The display devices are called output units of computer, Some example of output devices of computers are, Monitor, Printer, plotters etc.
What is keyboard of computer?Ans- A computer keyboard is a typewriter-style device which uses an arrangement of buttons or keys to act as mechanical levers or electronic switches.
What is computer mouse?Ans- A computer mouse is a hand-held pointing device that detects two-dimensional motion relative to a surface.
What are the types of memory?Ans- There are 6 types of computer memory, for details about the computer memory visit my article various types of memory on the computer.
- Registers
- Internal cache
- External cache
- Main memory
- Secondary
Ans- A web browser (commonly referred to as a browser) is a software application for accessing information on the World Wide Web. When a user requests a web page from a particular website, the web browser retrieves the necessary content from a web server and then displays the page on the user's device.
What is taskbar in computerAns- A taskbar is an element of a graphical user interface which has various purposes. It typically shows which programs are currently running. The specific design and layout of the taskbar varies between individual operating systems, but generally assumes the form of a strip located along one edge of the screen.
What is menu barAns- A menu bar is a graphical control element which contains drop-down menus. The menu bar's purpose is to supply a common housing for window- or application-specific menus which provide access to such functions as opening files, interacting with an application, or displaying help documentation or manuals.
What is CD-ROM?Ans- CD ROM stands for compact disk read-only memory. It is one of the secondary memory storage units.
