One of the most important components of a computer is storage. All computers have ways to work with and store data. When a computer manipulates data, it places it in a short-term storage location. When a computer stores data, it is placed in a long-term storage location. What are the two terms we use for a short-term and long-term storage location? (Select two.)

RAM, or random access memory, is considered volatile memory. RAM is extremely important as it is where the central processing unit (CPU) stores the information it is currently working on. The CPU can store and retrieve data from RAM at high speeds. The only issue with RAM is when the power is removed from the computer, all data is lost, hence the term volatile memory. Non-volatile storage is a place to put data to keep it from being lost if power is removed from the computer. Devices that fall under this title are a computer's hard drive, CD-ROMs, ROM chips, and flash drives.

You are trying to connect a new USB device to your computer. You install the driver and then connect the device to an open USB port. The device does not work. Which of the following troubleshooting steps is the BEST to try first?

The first thing to check is whether the USB device is plugged in properly. If that doesn't correct the problem, you might try a different USB cable before doing more extensive troubleshooting. You should only replace the device or install a new USB controller card after verifying where the problem lies. For example, if you try the device on another computer and it still doesn't work, you might assume that the device is defective.

Which type of storage media is susceptible to data loss due to excessive jostling or movement?

The most common type of long-term storage is the hard disk drive (HDD). Hard disks use thick, magnetic disks encased in a protective housing to store data. Because a hard disk drive is usually installed inside of a computer, it can be difficult to move one between systems. If you need a portable hard disk, use an external hard disk drive that uses a USB or FireWire connection to the computer. Hard disks can store a large amount of data, but because they rely on moving parts, they are prone to failure if they are shaken or jostled too much.
