Basic Quiz For Understanding IT Terminology

Operating systems are typically stored on a computer's hard drive. The hard drive is a physical storage device that permanently stores data, including the operating system files. The operating system is necessary for the computer to function properly, as it manages all the hardware and software resources. Storing the operating system on the hard drive allows the computer to access it quickly and efficiently whenever it is needed.

The password "12Motherwe1192" would be the best practice when creating a password because it includes a combination of uppercase and lowercase letters, numbers, and special characters. This makes it more secure and harder for hackers to guess. Additionally, it is a longer password, which also adds to its strength.

Digital cameras measure resolution in mega pixels. Resolution refers to the amount of detail that can be captured in an image, and it is commonly measured in mega pixels. Mega pixels indicate the number of individual dots or pixels that make up an image. The higher the mega pixel count, the more detailed and higher quality the image will be. Therefore, mega pixels is the correct unit of measurement for resolution in digital cameras.

A personal computer is another commonly known name for a computer. This term refers to a computer that is designed for individual use, typically used in homes, offices, and schools. It is a general-purpose machine that can perform various tasks such as word processing, internet browsing, gaming, and more. The term "personal computer" is widely recognized and used to describe desktop computers, laptops, and even tablets that are used by individuals for personal use.

The floppy disk has the lowest storage capacity among the given options. Floppy disks were commonly used in the past for data storage but had limited capacity. They typically had storage capacities ranging from 1.44 MB to 2.88 MB, which is significantly lower compared to other options like hard drives, memory sticks, and DVD-Rs. Hard drives can have storage capacities in terabytes, memory sticks typically range from a few gigabytes to several terabytes, and DVD-Rs have capacities ranging from 4.7 GB to 9 GB. Therefore, the floppy disk has the lowest storage capacity.

A memory stick is the best option for taking a backup of files in college because it is portable, has a large storage capacity, and can easily be connected to different devices. DVDs are not as portable and have limited storage capacity. Floppy disks are outdated and have very limited storage capacity. MP3 players are primarily used for playing music and do not have enough storage capacity for backing up files.

A mainframe is not classified as a portable computer because it is a large, powerful, and centralized computer system that is designed to handle extensive processing and storage tasks for multiple users simultaneously. Unlike laptops, tablets, and PDAs, which are designed to be lightweight and easily transported, mainframes are typically housed in dedicated data centers and require specialized infrastructure and cooling systems. They are not intended to be moved or used on the go like portable computers.

If you have a virus on your computer, one of the possible consequences is that a message may appear when trying to open a recently saved file, informing you that it is corrupt. Viruses can infect and damage files, causing them to become unreadable or corrupted. This can result in error messages when attempting to access these files.

A microphone is the correct answer for audio input as it is specifically designed to capture sound and convert it into an electrical signal that can be processed by a computer or other audio devices. Speakers are used for audio output, camera is used for capturing images or videos, and a scanner is used for scanning documents or images. Therefore, a microphone is the most suitable input device for audio input.

Using an office chair that can be adjusted for height is considered good practice when working at a computer because it allows for proper ergonomics. Adjusting the chair to the correct height ensures that the user's feet are flat on the floor, their knees are at a 90-degree angle, and their arms are at a comfortable height for typing and using the mouse. This helps to prevent strain and discomfort in the neck, back, and wrists, promoting better posture and reducing the risk of musculoskeletal issues.

A mainframe computer is most likely to be found in a bank because banks require robust and secure computing systems to handle large volumes of financial transactions, manage customer accounts, and ensure data privacy and security. Mainframes are known for their high processing power, reliability, and ability to handle multiple tasks simultaneously, making them ideal for handling the complex and critical operations of a bank. Additionally, mainframes are capable of supporting multiple users and applications, which is essential in a banking environment where numerous employees and customers need access to the system simultaneously.

In an architect's office, a plotter printer is more likely to be found. This is because architects often need to print large-scale drawings and plans, which cannot be accommodated by standard inkjet or laser printers. Plotters are specifically designed for printing large-format documents and can produce high-quality prints with precise details and accurate colors. Therefore, a plotter printer is the most suitable option for architects to meet their specific printing requirements.

A touch screen is considered an output device because it displays information and allows the user to interact with the device by touching the screen. It provides visual feedback and outputs the user's input to the device. In contrast, a keyboard, microphone, and webcam are input devices as they are used to input data or commands into the device.

CD-R (Compact Disc-Recordable) is the correct answer because it is a type of optical disc that can be written to only once. It has a storage capacity of 700MB, which makes it suitable for storing data, music, or videos. Floppy disks have a much lower storage capacity, typically ranging from 1.44MB to 2.88MB. CD-ROM (Compact Disc-Read Only Memory) is a type of disc that can only be read, not written to. DVD-RW (Digital Versatile Disc-Rewritable) has a much higher storage capacity than 700MB, usually ranging from 4.7GB to 9GB.
