A+ Certification Quick Quiz

1. A MB is bigger than a GB

True

False

The given answer is false because a MB (megabyte) is smaller than a GB (gigabyte). In terms of digital storage, a gigabyte is equal to 1024 megabytes. Therefore, a GB is larger in size compared to a MB.

Explanation

The given answer is false because a MB (megabyte) is smaller than a GB (gigabyte). In terms of digital storage, a gigabyte is equal to 1024 megabytes. Therefore, a GB is larger in size compared to a MB.

2. CD-ROM Drives can only read CD's

True

False

CD-ROM Drives- can only read CD's
CD-RW Drives- Can read from and write to CD's

Explanation

CD-ROM Drives- can only read CD's
CD-RW Drives- Can read from and write to CD's

3. Which Type of printer produces High-Quality images using the electophotographis process?

Dot Matrix

Inkjet

Laser Printer

Thermal Printer

A laser printer produces high-quality images using the electrophotographic process. This process involves a laser beam that creates an electrostatic image on a photosensitive drum. The drum is then coated with toner, which is attracted to the electrostatic image and transferred onto the paper. The result is a sharp and precise image with high resolution and clarity. Dot matrix printers use a matrix of pins to create characters and images, which may not achieve the same level of quality. Inkjet printers use liquid ink sprayed onto the paper, while thermal printers use heat to transfer images, both of which may not produce as high-quality results as a laser printer.

4. Serial connectors are typically 9 or 25 pin connectors

True

False

Serial connectors are typically 9 or 25 pin connectors. This statement is true because serial connectors, also known as RS-232 connectors, are commonly found in two sizes: 9 pin and 25 pin. These connectors are used to transmit data serially, meaning one bit at a time, and are commonly used for connecting devices such as modems, printers, and serial mice to computers. The 9 pin connector is more commonly used in modern devices, while the 25 pin connector is more commonly found in older devices.

5. Tracks on a hard drive are divided into?

Sectors

Clusters

Platters

Cylinders

Tracks on a hard drive are divided into sectors. Sectors are the smallest storage units on a hard drive and are used to store data. Each sector typically holds a fixed amount of data, usually 512 bytes. The division of tracks into sectors allows for efficient organization and retrieval of data on the hard drive.
