Basic Computer Knowledge Assessment

A printer is an output device that produces output on paper. It is commonly used to print documents, images, and other electronic files. Unlike a monitor, keyboard, or mouse, which are input devices, a printer is specifically designed for generating physical copies of digital information. It does so by transferring ink or toner onto paper, resulting in a printed document or image.

A mouse is a pointing device that is used to move a pointer on the screen and make selections. It is a small handheld device that typically has buttons and a scroll wheel, allowing users to navigate and interact with graphical user interfaces. The mouse's movement is translated into corresponding movements of the pointer on the screen, making it an essential tool for computer navigation and input.

Microsoft Word is a program used to create documents such as letters, essays, and resumes. It provides a user-friendly interface with various formatting tools and features that allow users to easily create and edit text-based documents. Microsoft Word also offers templates for different types of documents, making it a popular choice for creating professional-looking resumes, letters, and essays.

This statement is false because computers can be used for various purposes other than work. Computers can be used for entertainment, communication, education, research, gaming, and many other activities apart from work. Therefore, the statement that computers can only be used for work is incorrect.

The term "hardware" refers to the physical components of a computer, including the monitor, keyboard, memory chips, and hard drive. These are tangible objects that can be seen and touched. Software, on the other hand, refers to the programs and instructions that tell the hardware what to do. Firmware is a type of software that is permanently stored in a computer's hardware, providing low-level control over its operation. Output refers to the information or results that a computer produces.

The correct answer is Binary System. The binary number system is a base-2 number system that uses only two digits, 0 and 1. It is widely used in computer science and digital electronics, as it represents information using bits, which can be easily represented by electronic devices. The other options, C++ System, Teritiary System, and IO System, are not valid number systems and do not fit the description given in the question.

The CPU, or Central Processing Unit, is responsible for writing data and instructions in storage devices and performing calculations and other data processing. It is the brain of the computer and carries out all the necessary operations to execute tasks and run programs. The CPU interacts with the memory and storage devices to read and write data, and it performs complex calculations and manipulations on the data according to the instructions provided. Therefore, the CPU is the correct answer to the given question.

Software refers to the set of instructions that directs the hardware in a computer to accomplish a task. Software is a collection of programs, data, and instructions that tell the computer how to perform specific operations. It includes operating systems, applications, and other programs that enable the hardware to function and perform tasks as desired.
