Question 1
Which device would you typically plug into an AGP slot on a motherboard?
The Accelerated Graphics Port (AGP) was a high-speed point-to-point channel specifically designed for attaching a video card to a computer's motherboard. It was created to assist in the acceleration of 3D computer graphics by providing a dedicated path between the graphics processor and system memory, though it has since been largely replaced by PCI Express.

Question 2
Input/output buses were introduced primarily to slow down data transfer for better system synchronization.
This statement is false. I/O buses were actually introduced to provide faster data transfer rates between the CPU and peripheral devices. By creating specialized pathways for data to travel, the system can handle higher volumes of information more efficiently, which significantly improves overall system performance and responsiveness during complex tasks.

Question 3
Dark marks made with a pencil or ink are detected by an OMR (Optical Mark Reader) because they absorb light rather than reflecting it.
OMR technology works by shining a beam of light onto a document. The paper reflects light, but areas with dark pencil or ink marks absorb the light. The reader detects the lack of reflected light in those specific positions and translates that data into a digital response, making it highly efficient for grading multiple-choice tests.

Question 4
When purchasing a computer specifically for high-end graphics work and digital image creation, it is most important to select a system with:
Graphics work is resource-intensive. A fast processor handles complex calculations, large RAM allows the computer to keep high-resolution image data active without slowing down, and a large hard drive is necessary to store the massive file sizes associated with high-quality digital artwork and project assets.

Question 5
Which type of software application is specifically used to create professional-looking cards, flyers, calendars, and banners?
Desktop Publishing (DTP) software, such as Microsoft Publisher or Adobe InDesign, provides advanced layout tools that standard word processors lack. It allows users to manipulate text and images with great precision on a page, making it the ideal choice for designing promotional materials like banners, flyers, and brochures.

Question 6
By default, when you open the Print dialogue box in most applications, how many copies of the document are set to be printed?
The standard default setting for the number of copies in a print dialogue box is 1. This is a safety feature designed to prevent the accidental wasting of paper and ink. If a user requires multiple copies, they must manually adjust this numerical value before confirming the print command.

Question 7
Which of the following groups consists entirely of input devices?
Input devices are used to send data to the computer. A keyboard (text), graphics tablet (drawings), mouse (navigation), and concept keyboard (specialized buttons) all perform this function. Other options are incorrect because they include output devices like printers, plotters, and speakers which receive data from the computer.

Question 8
The primary storage device in the computer that holds essential start-up data and instructions permanently is:
Read-Only Memory (ROM) is non-volatile, meaning it retains its data even when the computer is turned off. It stores the 'firmware' or BIOS instructions that tell the hardware how to function and how to load the operating system when the computer is first powered on.

Question 9
The process of loading the operating system software into the computer's memory to start up the system is known as:
Booting is the initialization process that happens when you turn on a computer. During this phase, the hardware performs a self-test and then the ROM BIOS locates and loads the operating system files from the hard drive into the RAM, allowing the user to begin interacting with the computer.

Question 10
Which of the following devices can operate as both an input and an output communication device?
A Modem (Modulator-Demodulator) acts as both an input and output device. It 'outputs' data by converting digital signals from your computer into analog signals to be sent over lines, and it 'inputs' data by receiving incoming analog signals and converting them back into digital data for your computer to process.
