The physical arrangement of elements as input, output and processing devices grouped together represents a
Correct Answer
D. Computer system
Explanation
The physical arrangement of elements as input, output, and processing devices grouped together represents a computer system. A computer system consists of various hardware components such as the central processing unit (CPU), memory, storage devices, input devices (like keyboard and mouse), and output devices (like monitor and printer). These components work together to process information and perform tasks. Therefore, the given answer of "computer system" is correct in this context.
2.
What type of computer could be found in a digital watch?
Correct Answer
E. None of these
Explanation
A digital watch typically contains an embedded computer. Embedded computers are designed to perform specific tasks and are often found in everyday devices such as watches, appliances, and cars. Mainframe computers and supercomputers are much larger and more powerful, used for complex calculations and large-scale data processing. Notebook computers, also known as laptops, are portable personal computers. Therefore, none of these options accurately describe the type of computer found in a digital watch.
3.
Which is not a basic function of a computer ?
Correct Answer
A. Copy text
Explanation
Copying text is not a basic function of a computer. The basic functions of a computer include accepting input, processing data, and storing data. Copying text is a specific task that can be performed on a computer but is not considered a fundamental function.
4.
These are specially designed computer chips reside inside other devices, such as your car or your electronic thermostat
Correct Answer
B. Embedded computers
Explanation
Embedded computers are specially designed computer chips that reside inside other devices, such as cars or electronic thermostats. These computers are programmed to perform specific functions within the device they are embedded in. Unlike servers, mainframes, or robotic computers, embedded computers are not standalone devices but are integrated into other systems to provide dedicated functionality.
5.
It is the set of programs that enables your computer's hardware devices and application software to work together
Correct Answer
D. System Software
Explanation
System software refers to a collection of programs that facilitate the coordination and interaction between a computer's hardware devices and application software. It includes operating systems, device drivers, and utility programs that ensure the smooth functioning of the computer system. System software acts as an intermediary between the hardware and software, providing a platform for applications to run efficiently. It manages the computer's resources, controls peripheral devices, and provides a user-friendly interface for users to interact with the computer.
6.
The most frequently used instructions of a computer program are likely to be fetched from
Correct Answer
B. Cache memory
Explanation
The most frequently used instructions of a computer program are likely to be fetched from cache memory. Cache memory is a small, high-speed memory located close to the CPU. It stores frequently accessed data and instructions to reduce the time it takes to access them from the slower main memory (RAM) or even slower storage devices like the hard disk. By keeping frequently used instructions in cache memory, the computer can quickly retrieve them, improving overall program execution speed.
7.
The components that process data are located in the
Correct Answer
C. System unit
Explanation
The components that process data are located in the system unit. The system unit is the main component of a computer that houses the motherboard, CPU, memory, and other essential hardware components. These components work together to process data and perform calculations. Input and output devices, such as keyboards, mice, monitors, and printers, are responsible for sending and receiving data to and from the system unit, but they do not actually process the data themselves. The storage component, on the other hand, is responsible for storing data but does not process it. Therefore, the correct answer is the system unit.
8.
Which type of data has been organized or presented in a meaningful fashion?
Correct Answer
D. Information
Explanation
Information is the correct answer because it refers to data that has been processed, organized, or presented in a way that is meaningful and useful. Data on its own may not have any significance, but when it is transformed into information, it becomes valuable and can be used to make informed decisions or gain insights.
9.
A computer gathers data, process it, outputs the data or information and ........ the data or information.
Correct Answer
B. Stores
Explanation
After processing the data and generating the desired output, a computer typically stores the data or information for future use. Storing the data allows the computer to retain the processed information and make it available for further analysis or retrieval when needed. Therefore, "stores" is the correct answer as it accurately describes the action taken by a computer after processing and outputting the data.
10.
A ............ is a microprocessor based computing device.
Correct Answer
A. Personal computer
Explanation
A personal computer is a microprocessor based computing device that is designed for individual use. It is a small and portable device that can perform various tasks such as word processing, internet browsing, and multimedia playback. Unlike mainframes, workstations, and servers, personal computers are typically used by one person at a time and are not intended for large-scale computing or network operations.
11.
Which type of software is distributed free but requires the users to pay some amount for further use?
Correct Answer
A. Freeware
Explanation
Freeware is a type of software that is distributed for free to users. However, in some cases, freeware may require users to pay a certain amount for additional features or extended usage. This payment is optional and not mandatory for the basic functionality of the software. Therefore, freeware fits the description of software that is distributed free but requires users to pay some amount for further use.
12.
External devices such as printers, keyboards and modems are known as
Correct Answer
B. PeripHerals
Explanation
External devices such as printers, keyboards, and modems are commonly referred to as peripherals. Peripherals are additional hardware devices that can be connected to a computer system to enhance its functionality or provide additional features. They are not an integral part of the computer system but rather add-on devices that can be connected or disconnected as needed. Therefore, the term "peripherals" accurately describes these external devices.
13.
The CPU and memory are located on the
Correct Answer
B. Motherboard
Explanation
The CPU (Central Processing Unit) and memory are essential components of a computer system, and they are both located on the motherboard. The motherboard is the main circuit board that connects all the other components of the computer, including the CPU, memory, storage devices, and output devices. It provides the necessary pathways for data transfer and communication between these components. Therefore, the motherboard is the correct answer as it houses the CPU and memory.
14.
The thing which easily understands the instructions is called
Correct Answer
A. User friendly
Explanation
User friendly refers to a system or device that is designed in a way that is easy for users to understand and operate. It implies that the instructions and interface are clear, intuitive, and accessible, allowing users to easily navigate and interact with the system without confusion or difficulty. This term is commonly used to describe software, websites, and other technological devices that prioritize usability and a positive user experience.
15.
Storage that retains its data after the power is turned off is referred to as
Correct Answer
B. Non-volatile storage
Explanation
Non-volatile storage refers to a type of storage that retains its data even when the power is turned off. This means that the data stored in non-volatile storage remains intact and accessible even after a power outage or system shutdown. In contrast, volatile storage, such as RAM, loses its data when the power is cut off. Sequential storage and direct storage are not relevant terms in this context. Therefore, the correct answer is non-volatile storage.
