An operating system is a program that acts as an interface between the user and the computer and vice-versa. It manages the computer's hardware and software resources, provides a user-friendly interface for users to interact with the computer, and allows applications to run efficiently. It handles tasks such as memory management, file management, process management, and device management. The operating system plays a crucial role in providing a platform for users to execute commands and access various functionalities of the computer system.

The small blinking line on a monitor is commonly known as the cursor. It indicates the current position where text or graphics will be inserted when typing or inputting data. The cursor can be moved using the arrow keys on the keyboard or by clicking on a different location on the screen.

Control Panel is the tool that is used to change the keyboard and mouse settings in Windows 95. It provides access to various settings and configurations of the operating system, including input devices such as the keyboard and mouse. By accessing the Control Panel, users can modify settings such as keyboard layout, mouse sensitivity, button configuration, and other related options to customize their input devices according to their preferences.

The number of dots (pixels) on the screen is a measure of the resolution of a monitor. Resolution refers to the number of pixels displayed on the screen horizontally and vertically. A higher resolution means a greater number of pixels, resulting in a clearer and more detailed image.

A program is a set of instructions or code that is given to a computer to perform a specific task. It can be written in various programming languages and is used to control the behavior of a computer or other electronic devices. A program can perform calculations, manipulate data, and interact with users or other software. Therefore, a program is the correct answer as it accurately describes a task given to a computer.

The correct answer is 1024 KB because in the binary system, 1 MB is equal to 1024 KB. This is because each kilobyte (KB) is equal to 1024 bytes, and since there are 1024 kilobytes in a megabyte (MB), the conversion is 1024 KB = 1 MB.

EEPROM stands for Electrically Erasable Programmable Read Only Memory. This type of memory can be erased and reprogrammed electrically, making it a versatile and flexible option for storing data. Unlike traditional Read Only Memory (ROM), which cannot be modified, EEPROM allows for changes to be made to the stored data. This makes it an ideal choice for applications where data needs to be updated or modified frequently.

Application software refers to a type of software that is designed to perform specific tasks or applications for users. Unlike system software, which manages and controls the computer hardware and provides a platform for running applications, application software is focused on providing functionality and features to the end user. It can be used for various purposes such as word processing, spreadsheet management, graphic design, and more. Therefore, the correct answer is application software.

The correct answer is system software. An operating system is a type of system software that manages computer hardware and software resources and provides common services for computer programs. It acts as an intermediary between the user and the computer hardware, allowing users to interact with the computer and run applications. System software refers to programs that control and manage the computer system, including the operating system, device drivers, and utility programs. Application software, on the other hand, refers to programs designed to perform specific tasks for the user, such as word processing, spreadsheet management, or web browsing.

A boot sector virus is a type of dangerous virus that infects the boot sector of a computer's hard drive or removable storage devices. It is capable of spreading and infecting other computers through infected files or bootable disks. Once the virus is executed during the boot process, it can corrupt or overwrite critical system files, leading to system crashes, data loss, or unauthorized access to personal information. Therefore, a boot sector virus poses a significant threat to the security and stability of a computer system.

Batch processing is a method of processing data in which a group of similar tasks are executed together as a batch. In this method, input data is collected and stored in a source document before being converted into a machine-readable form. This allows for efficient processing of large amounts of data in a sequential manner, as opposed to processing data in real-time or online. Therefore, the correct answer is batch.

IBM4381 is an example of a mainframe computer. Mainframe computers are large and powerful machines that are designed to handle complex and demanding tasks. They are typically used by large organizations for tasks such as processing large amounts of data, running critical applications, and managing networks. The IBM4381, being a mainframe computer, would have the capabilities and specifications required to handle such tasks efficiently.

The correct answer is "power On Sell Test" because the acronym POST stands for Power On Self Test. This refers to the automatic diagnostic test that a computer performs when it is turned on to check for any hardware or software issues.

A device driver is a small program that enables a hardware or device to function properly. It acts as a bridge between the operating system and the hardware, allowing the operating system to communicate with and control the device. Without a device driver, the hardware or device would not be able to work as intended.

Macros in MS-DOS are stored in the RAM because they are temporary programs that are created and executed within the computer's memory. RAM (Random Access Memory) is a volatile storage location that allows for quick access and retrieval of data, making it suitable for storing and running macros. Storing macros in RAM also allows for easy modification and deletion of the macros as needed.

Computers can be used for general purpose and different applications. The term "digital" refers to the use of discrete values or digits, which is the fundamental basis of computer technology. Computers process and store data in binary form, using 0s and 1s to represent information. This allows computers to perform a wide range of tasks and applications, from basic calculations to complex data analysis, communication, and multimedia processing. The term "digital" accurately describes the nature and capabilities of computers in their general purpose and various applications.

One example of a limitation of computers is their inability to detect errors. Unlike humans, computers are not capable of identifying mistakes or inconsistencies in data or calculations without specific instructions to do so. This can lead to incorrect outputs or inaccurate information being processed and stored by the computer system.

IBM-AS400 is an example of a mini computer. Mini computers are mid-sized computers that are larger and more powerful than microcomputers but smaller and less powerful than mainframe computers. The IBM-AS400, also known as the IBM iSeries, was a popular mini computer system developed by IBM. It was designed for small to medium-sized businesses and offered a combination of mainframe and microcomputer features, making it a hybrid computer. Therefore, the correct answer is mini computer.

The correct answer is Novel Operating System version 4.1. This is because the question asks for an example of a GUI operating system, and Novel Operating System version 4.1 is known for its graphical user interface. MS-DOS and Oracle Power Objects are not GUI operating systems, while Windows 3.11 is a GUI operating system but it is not the correct answer in this case.

The correct answer is Dynamic Ram because Ram stands for Random Access Memory, which is a type of computer memory that can be accessed randomly. Both Static Ram and Dynamic Ram are types of Ram, but Dynamic Ram is specifically mentioned in the question. Therefore, it can be inferred that Dynamic Ram is used on the Primary Storage Sections.
