What does USB stand for and what is it used for?

United Standard Bios. Balances Bio chips inside a computers motherboard for plugin devices.
Under Stated Blinker. Special internal plug light.
Universal Serial Bus. A type of plug that can be used on any computer to plug in a mouse, printer, or keyboard.

Correct Answer

A. Universal Serial Bus. A type of plug that can be used on any computer to plug in a mouse, printer, or keyboard.

Explanation

The correct answer is "Universal Serial Bus. A type of plug that can be used on any computer to plug in a mouse, printer, or keyboard." This answer correctly identifies USB as an acronym for Universal Serial Bus, which is a standard interface used for connecting various devices to a computer, such as mice, printers, and keyboards. It highlights the versatility of USB, as it can be used on any computer regardless of the brand or model.

In a computer what is a GHz?

A gigahertz. It indicates the power level of a computers processing chip.
A gigabite. It indicates the memory level of a computers processing chip.
A gigawatt. It indicates the light level of a computers monitor.

Correct Answer

A. A gigahertz. It indicates the power level of a computers processing chip.

Explanation

A gigahertz (GHz) is a unit of measurement used to describe the speed at which a computer's processor can execute instructions. It represents the number of cycles that the processor can complete in one second. A higher GHz value generally indicates a faster processor and therefore a higher processing power. This measurement is important for determining the performance capabilities of a computer and its ability to handle complex tasks efficiently.

If your computer freezes or has major memory problems what should you do first?

Unplug it
Reboot
Pray
Nothing, just live with it.

Correct Answer

A. Reboot

Explanation

If your computer freezes or has major memory problems, the first thing you should do is reboot it. Rebooting helps to refresh the system and clear any temporary issues that may be causing the freezing or memory problems. It allows the computer to start fresh and can often resolve the problem without any further intervention.

What is a hard drive?

A drive that is hard to remove from a computer once installed.
A temporary memory chip measured in gigabytes that operates software.
A disk shaped storage device that permanently stores data on a computer.

Correct Answer

A. A disk shaped storage device that permanently stores data on a computer.

Explanation

The correct answer is a disk shaped storage device that permanently stores data on a computer. A hard drive is a non-volatile storage device that uses magnetic storage to store and retrieve digital information. It consists of one or more rotating disks, or platters, which are coated with a magnetic material. Data is written and read from the platters using a magnetic head that moves across the surface of the disk. Hard drives are commonly used in computers to store operating systems, software, and user data. They provide long-term storage and can retain data even when the computer is powered off.

Based on the specifications of the 3 computers listed below which one would run the fastest:

IMac, OS X Panther, 4 RAM, 600 GB Harddrive, 24" monitor, 1.30 GHz
IMac, OS X Tiger, 8 RAM, 600 GB Harddrive, 20" monitor, 1.30 GHz
Power Mac, OS X Panther, 1 TB RAM, 600 GB Harddrive, 24" monitor, 1.33 GHz

Correct Answer

A. Power Mac, OS X Panther, 1 TB RAM, 600 GB Harddrive, 24" monitor, 1.33 GHz

Explanation

The Power Mac would run the fastest because it has the highest amount of RAM (1 TB) compared to the other two computers. RAM is an important factor in determining the speed of a computer as it affects the ability to run multiple programs and handle large amounts of data efficiently. The processor speed (1.33 GHz) is also slightly higher than the iMac with OS X Panther (1.30 GHz), which could contribute to faster performance. The size of the hard drive and monitor does not significantly impact the overall speed of the computer.

What is RAM?

A temporary memory chip measured in gigabytes that operates software.
A memory chip that permanently stores data on a computer.
A graphics chip that runs the monitor of the computer.

Correct Answer

A. A temporary memory chip measured in gigabytes that operates software.

Explanation

RAM stands for Random Access Memory, which is a temporary memory chip measured in gigabytes. It is responsible for storing data that is actively being used by the computer's software, allowing for quick access and retrieval. Unlike permanent storage options such as hard drives or solid-state drives, RAM is volatile and loses its data when the computer is powered off. Therefore, it is crucial for the smooth operation of software and multitasking capabilities of a computer system.
