In a computer system, IRQs (Interrupt Requests) are used to manage hardware interrupts, which allow devices to communicate with the CPU. On the other hand, I/O (Input/Output) addresses are used to access hardware devices and their corresponding registers.

The number of available IRQs is typically limited, usually ranging from 16 to 24, depending on the system. In contrast, there is a much larger range of I/O addresses available.

Due to the limited number of IRQs, conflicts can occur when multiple devices attempt to use the same IRQ simultaneously. This can lead to hardware resource conflicts, causing malfunctions or failures.

While I/O conflicts can also occur if multiple devices try to use the same I/O address, the likelihood of such conflicts is lower because there are typically many more available I/O addresses compared to the number of IRQs.

Therefore, it is more likely for a hardware resource conflict to be an IRQ conflict rather than an I/O conflict.

PCMCIA (Personal Computer Memory Card International Association) cards come in three different types, based on their thickness and dimensions:

• Type 1: These cards have a thickness of 3.3mm.
• Type 2: These cards have a thickness of 5.0mm.
• Type 3: These cards have a thickness of 10.5mm.

Since the measurement provided is 10.5mm, it corresponds to a type 3 PCMCIA card. Therefore, the correct answer is D. type 3.

IBM's Micro Channel Architecture, introduced in the 1980s, was a proprietary expansion bus architecture used in IBM's personal computers. MCA supported two different bit access widths: 16-bit and 32-bit. This allowed for higher data transfer rates and greater expansion capabilities compared to the previous 8-bit and 16-bit bus architectures.

An output device is any piece of computer hardware equipment which converts information into human-readable form. It can be text, graphics, tactile, audio, and video. Some of the output devices are Visual Display Units (VDU) i.e. a Monitor, Printer, Graphics Output devices, Plotters, Speakers etc:

• A Visual Display Unit is the most popular output device used for producing soft copy output generated by a computer or other electronic devices.
• It is commonly known as a  Monitor. a V.D.U. may be peripheral or may be integrated with the other components. Early V.D.U. were primarily Cathode Ray Tube (CRT) displayed and typically had a diagonal size of 13 inches or less.
• During the 1990s, 15" and 17" displays became standard, and some manufacturers began producing displays over 20" in size. At the turn of the century, flat panel displays became more common, and by 2006, CRT displays were hard to find.
• Today, it is common for computers to come with VDUs that are 20" to 30" in size. Thanks to the recent growth in LCD, plasma, and LED technology, manufacturing large screens is much more cost-effective than before.

Note: Magnetic Ink Character Recognition (MICR), Optical Character Recognition (OCR), Optical Mark Reading (OMR) are all input devices. In computing, an input device is a piece of computer hardware equipment used to provide data and control signals to an information processing system such as a computer or information appliance. Examples of input devices include keyboards, mouse, scanners, digital cameras, joysticks, and microphones.

Hence, we conclude that the Visual Display Unit (VDU) is an output device.

Concept:

ROM- Read-Only Memory (ROM) chips are non-volatile memory that generally contains instructions for "booting" the computer (i.e. loading the operating system when the computer starts up).

For 2ⁿ × m ROM chips we have:

1. n address lines.

2. m bit data lines. 

The total capacity of ROM chips required = Number of ROM chips × Capacity of single ROM chip

Analysis:

Given, the capacity of single-chip = 2k × 8

Required capacity = 16k × 8

Number of ROM chips required = 

= 8

Register renaming is a technique used in pipelined processors to mitigate hazards, specifically register data hazards. It allows the processor to dynamically assign temporary or renamed registers to instructions in order to avoid data dependencies and enable instructions to execute concurrently in the pipeline without data hazards. By renaming registers, the processor can ensure that instructions with conflicting dependencies can be executed in parallel without causing data hazards.

A CRT (Cathode Ray Tube) is a display technology that was commonly used in older televisions and computer monitors. It consists of a large, bulky tube with a rectangular screen. The image is displayed on the screen using an electron beam that scans across the screen horizontally, from left to right and top to bottom, illuminating phosphor dots on the inside of the screen to create the visual display.

Internet Explorer is a web browser software developed by Microsoft. It allows users to browse and navigate the internet, view websites, and interact with web-based content. It is installed on a computer and used as a software application to access the internet.

The other options listed are hardware devices rather than software.

B. Keyboard - A keyboard is a hardware input device used to input text and commands into a computer system. C. Scanner - A scanner is a hardware device used to convert physical documents or images into digital format. D.

Printer - A printer is a hardware output device used to produce physical copies of digital documents or images.

The speed of a line printer is primarily limited by the speed at which the paper can be moved through the printer. Line printers work by printing one line of text at a time, typically by striking an inked ribbon against the paper. To print subsequent lines, the paper needs to be advanced to the next line position.

The speed of the cartridge used or the length of the paper typically do not directly limit the speed of a line printer. The cartridge used may affect the quality or efficiency of the printing process, but it does not directly impact the speed. The length of the paper may affect the total time required to print a document, but it does not affect the speed at which each line is printed.

Therefore, the correct answer is B. paper movements.

The term used to describe the intangible instructions that tell the computer what to do is software. Software refers to a collection of programs, data, and instructions that are used to operate a computer and perform specific tasks. It includes operating systems, applications, programming languages, and other programs that enable the computer to perform various functions and tasks based on the given instructions.

Hardware, on the other hand, refers to the physical components of a computer system, such as the processor, memory, motherboard, storage devices, input/output devices, and so on. Hardware provides the physical infrastructure for executing the instructions provided by the software.

Storage and input/output (I/O) are concepts related to computer systems, but they do not specifically refer to the intangible instructions themselves. Storage refers to the media or devices used to store data and programs, while input/output refers to the communication between the computer and its external devices or users.

Therefore, the correct answer is A. software.

A mouse is a pointing and drawing device commonly used with computers. It allows users to move a cursor or pointer on the screen by physically moving the mouse across a flat surface.

C. Trackball - A trackball is another type of pointing device that functions similarly to a mouse. It consists of a ball that can be rotated with the hand or fingers to move the cursor on the screen.

D. Keyboard - A keyboard is an input device primarily used for entering text and commands into a computer system. While it is an essential input device, it is not classified as a pointing device because it does not directly control the movement of a cursor or pointer on the screen.

Therefore, the correct answer is D. keyboard.

A dot matrix printer is a type of printer that uses a matrix of small pins or wires to strike an ink ribbon and transfer ink onto paper, creating characters or images. It can only print one character at a time by sequentially activating the appropriate pins or wires to form each character.

During the fusing process in laser printing, toner is melted into the paper. The toner is initially dry, consisting of powdered ink particles. These particles are attracted to the paper using electrostatic charges and then heated to a high temperature. The heat causes the toner particles to melt and bond with the fibers of the paper, resulting in the permanent adhesion of the toner to the paper surface.

When testing a speaker in a computer using an ohmmeter (a device used to measure electrical resistance), the expected resistance reading can vary depending on the specific speaker design. However, in most cases, you would typically see a reading close to or approaching "Unlimited Ohms" or an open circuit.

Speakers are primarily designed to convert electrical signals into sound waves and are not intended to provide a significant resistance to the electrical current. Therefore, the ohmmeter will generally display a high resistance value, indicating that the speaker does not provide a direct path for electrical current to flow.

When not in use, it is important to keep 5.25-inch floppy diskettes (also known as 5 VA diskettes) in their protective sleeves. These protective sleeves are designed to shield the diskettes from dust, dirt, and other potential contaminants that could damage the delicate magnetic media inside.

The protective sleeves typically have a soft lining that helps prevent scratches and static buildup on the diskette surface. Additionally, the sleeves usually have a closure mechanism (such as a flap or zipper) to ensure that the diskette remains securely enclosed and protected.

Storing the diskettes in their protective sleeves helps to maintain their integrity and prolong their lifespan. It is not recommended to store them in a plastic bag, as static electricity can build up inside the bag and potentially damage the diskettes. Placing them on a shelf in an upright position can expose them to dust and other elements, increasing the risk of damage. Storing them in the floppy drive is also not recommended as it can expose them to dust and potential accidental damage. Therefore, using the provided protective sleeves is the best practice for keeping 5 VA diskettes safe when not in use.

ATAPI stands for "ATA Packet Interface." It is an interface standard that extends the ATA (Advanced Technology Attachment) interface to support devices other than traditional ATA hard disk drives, such as CD-ROM, DVD-ROM, and other mass storage devices.

Therefore, ATAPI compliance refers to the compliance of a device with the ATAPI standard, indicating that it is a mass storage device that can be connected and used with an ATA interface.
