When your Hard Disk is infected with a virus, the first thing you should do is to copy all your files to a floppy diskette. This is because the virus can potentially damage or corrupt your files, and by copying them to a separate diskette, you ensure that they are safely backed up and protected from further harm. This allows you to recover your important files even if the virus causes damage to your hard disk.

In Windows, when a file is deleted, it is not permanently removed from the system. Instead, it is sent to the Recycle Bin, where it can be restored if needed. This allows users to easily recover accidentally deleted files without the need for specialized recovery tools. However, once the Recycle Bin is emptied or the files are manually deleted from it, they are no longer easily recoverable.

The ALU (Arithmetic Logic Unit) is a fundamental component of a computer processor that performs arithmetic operations (such as addition, subtraction, multiplication, and division) and logical operations (such as AND, OR, and NOT). It is responsible for executing mathematical calculations and logical comparisons needed for data processing. Therefore, the correct answer is Arithmetic and Logical operations.

The correct answer is Arithmetic Logic Unit. ALU is an acronym for Arithmetic Logic Unit, which is a fundamental component of a computer processor. The ALU performs arithmetic operations (such as addition, subtraction, multiplication, and division) as well as logical operations (such as AND, OR, and NOT) on binary data. It is responsible for executing the instructions and manipulating the data within the processor, making it a crucial component in performing calculations and logical operations in a computer system.

To copy text matter in Notepad to the computer buffer, you need to press Ctrl and C. This keyboard shortcut allows you to copy the selected text and store it in the computer's clipboard or buffer. Once the text is copied, you can then paste it in another location or application by pressing Ctrl and V.

The memory (RAM) of a personal computer is considered hardware because it is a physical component of the computer system. Hardware refers to the tangible parts of a computer system that can be touched and interacted with, such as the motherboard, processor, and memory. In contrast, software refers to the programs and instructions that run on the hardware. Therefore, the memory (RAM) being a physical component of the computer system makes it a part of the hardware.

The ASCII character set uses 8 bits to represent each character. ASCII stands for American Standard Code for Information Interchange, and it is a character encoding standard that assigns unique numeric codes to represent characters. With 8 bits, a total of 256 unique characters can be represented, including letters, numbers, symbols, and control characters. Therefore, the correct answer is 8.

When a hard disk is infected with a virus, it is important to first copy all the files to a floppy diskette. This is because the virus may damage or corrupt the files on the hard disk, making it difficult to recover them later. By copying the files to a floppy diskette, you can ensure that your important data is safely stored and can be accessed even if the hard disk is further affected by the virus.

Computer viruses have the ability to link themselves to other programs, allowing them to spread and infect multiple files or systems. By attaching their code to other programs, viruses can easily transfer from one computer to another, often without the user's knowledge or consent. This ability to self-replicate and spread is a key characteristic of computer viruses and is a major concern for computer security.

The correct answer is Drag and Drop. In Windows 95, the easiest way to move a file from one folder to another is by dragging the file from its current location and dropping it into the desired folder. This can be done by clicking and holding the left mouse button on the file, dragging it to the target folder, and then releasing the mouse button to drop the file into the new location. This method is simple and intuitive, allowing for easy file management within the operating system.

The explanation for why Option 1 is the correct answer is not available.

To paste text matter into a Notepad text file, you can use the keyboard shortcut Ctrl and V. This shortcut allows you to paste the copied text from the clipboard into the Notepad file.

The word "SUMMER" consists of 6 characters. In computer memory, each character is typically stored as 1 byte. Therefore, to store the word "SUMMER" in computer memory, 6 bytes would be required.

The CPU (Central Processing Unit) is the main component of a computer that performs most of the processing inside the computer. It consists of three main components: ALU (Arithmetic Logic Unit), Registers, and CU (Control Unit). The ALU is responsible for performing arithmetic and logical operations, the Registers are small storage units used to store data temporarily, and the CU controls the flow of data and instructions within the CPU. Therefore, the correct answer is ALU, Registers, and CU.

The correct answer is "Micro-computers such as laptops." This statement is correct because micro-computers, which include laptops, are generally smaller and less powerful than mini-computers and mainframes. Mini-computers are typically more powerful than mainframes, and mainframes are designed for large-scale operations and are suitable for large companies, not small ones.

The main memory is composed of RAM, ROM, and Hard Disk. It can be either temporary or permanent. It is used to store user programs and data while they are running. The correct answer, b+c, indicates that the main memory consists of both RAM and ROM, as mentioned in the given information.

No, it is not possible to recover the unsaved content in Notepad after a computer reboot. When the computer restarts, all unsaved data is lost as it is not automatically saved by the program. It is always recommended to save your work periodically to avoid losing any important information in such situations.

The given answer, "Used to store user programs and data," is correct because one of the main functions of an operating system is to provide a platform for users to run their programs and store their data. The operating system manages the storage and organization of user programs and data, ensuring they are accessible and protected. This function is essential for users to effectively utilize their computer systems.

The given statement correctly identifies the magnetic disk as a secondary storage device. Secondary storage refers to non-volatile storage that can retain data even when the power is turned off. The magnetic disk fits this description as it uses magnetic materials to store data and is commonly used for long-term storage in computers. It is also mentioned that the magnetic disk is cheap, which is another characteristic of this type of storage. However, the statement incorrectly states that the magnetic disk is volatile, which is not true as secondary storage devices are non-volatile. The statement also does not provide any information about the magnetic disk being an output unit or the equation a+b, making them irrelevant to the correct answer.

The given statement "F-prot is one of the unti-virus programs" is not correct. F-prot is actually an antivirus program, not an "unti-virus" program. An antivirus program is designed to detect, prevent, and remove computer viruses, while "unti-virus" is not a recognized term in the context of computer security.

The correct answer is "Both of the above." This means that the sound plaster can function as both an input unit and an output unit. It is capable of receiving sound input and also producing sound output.

The CPU, or Central Processing Unit, is the correct answer. It is composed of an arithmetic-logic unit (ALU) and a control unit. The ALU performs mathematical and logical operations, while the control unit manages the flow of data and instructions within the computer. The CPU is often referred to as the "brain" of the computer, as it carries out the majority of the processing tasks.

The Network Neighborhood displays the drives and printers on your system that are available to the network. This means that other devices connected to the same network can access and use these resources. It does not guide you through a step-by-step process of connecting to the network, nor does it contain the names of the network neighborhood. Its main function is to show the shared drives and printers that can be accessed by other network users.
