Hello Friends,this section is specifically dedicated to those users who wants to clear the fundamental of computer science. Here we have included Computer General Knowledge multiple choice questions with answers(MCQs). Students can expect some questions from this section for sure in the respective university exams,competitive exams and interviews.So practice it well and enjoy with good score you expect.
1. A computer cannot ‘boot’ if it does not have the
- Compiler
- Loader
- Operating System
- Assembler
Necessary components to start up, such as a power supply, a CPU, and some form of storage device that contains the operating system or bootloader. Without these essential components, the computer will not be able to initiate the boot process, which is the sequence of operations that the computer goes through to start up and load the operating system into memory.
Additionally, the computer may require other components such as RAM, a graphics card, and other peripheral devices to fully function once it has booted up. However, these components are not strictly necessary for the initial boot process, which only requires the essential components mentioned above.
In summary, a computer cannot boot without the necessary components such as a power supply, CPU, and storage device containing the operating system or bootloader.
2. The amount of vertical space between lines of text in a document is called
- double-space
- line spacing
- single space
- vertical spacing
The amount of vertical space between lines of text in a document is called "line spacing." It refers to the distance between the baselines of two consecutive lines of text and is typically measured in points (pt) or as a multiple of the font size, such as 1.5 times or double the font size.
Line spacing can affect the readability and appearance of a document. A narrow line spacing can make text look cramped and difficult to read, while a wider line spacing can make a document look more open and easier to read. The appropriate line spacing depends on factors such as the font style, size, and type of document being created.
In many word processing and typesetting software programs, line spacing can be adjusted through formatting options or styles. This allows the user to customize the line spacing to suit their preferences or the requirements of the document being created.
3. Example of non-numeric data is
- Employee address
- Examination score
- Bank balance
- All of these
Non-numeric data refers to any type of data that is not represented by numerical values. Examples of non-numeric data include:
- Text data: This refers to any type of data that consists of letters, words, or sentences, such as names, addresses, or descriptions.
- Date and time data: This refers to data that represents a specific date or time, such as the date of birth, the date of an event, or the time a transaction occurred.
- Boolean data: This refers to data that can only take on one of two values, such as "true" or "false", "yes" or "no", or "on" or "off".
- Image data: This refers to data that represents an image or graphic, such as a photograph, a logo, or a chart.
- Audio and video data: This refers to data that represents sound or moving images, such as a song, a video clip, or a movie.
- Other non-numeric data: This includes data such as email addresses, website URLs, social media handles, and more.
4. What is embedded system?
- The programme which arrives by being wrapped in box.
- The programme which is the permanent part of the computer
- The computer which is the part of a big computer
- The computer and software system that control the machine
An embedded system is a computer system that is designed to perform specific tasks or functions within a larger system or device. Unlike general-purpose computers, which are designed to run a wide range of applications, embedded systems are typically built into a specific device or product and are dedicated to a single task or set of tasks.
Embedded systems can be found in a wide range of devices and products, from simple appliances such as microwave ovens and thermostats to more complex systems such as automotive engines and medical equipment. They are often used in applications where reliability, real-time performance, and low power consumption are critical factors.
An embedded system typically consists of three main components: a microcontroller or microprocessor, which serves as the "brain" of the system and controls its operation; input/output (I/O) devices, which allow the system to communicate with its environment and other devices; and memory, which stores the system's instructions and data.
Embedded systems are often designed to be highly efficient, using minimal resources to achieve their intended functionality. They may also be designed to operate without human intervention, or with minimal user input. The development of embedded systems requires specialized knowledge and skills in areas such as hardware design, software development, and system integration.
