What default installation folders contain system and application files that should not normally be deleted or modified manually?
The 'Windows' and 'Program Files' folders.
What view options could you use to show files of a particular type sorted by date?

What are the key features of a packet switching network?
Nodes within the network can perform a forwarding function, allowing a packet to utilize any available path through the network. This makes the network robust against link failures. If is beneficial for the network to use small packets that are easy to re-send.
Why can't you use memory modules designed for a desktop computer in a laptop?
Laptops use a smaller form factor called SO-DIMM while desktops use DIMMs.
What sort of device would you need to transfer data from a "Memory Stick?"
Memory card reader/multi-card reader. Do note that Memory Sticks are no longer in production so you could struggle to locate a suitable reader.

A hard drive is rated at 10,000 RPM. What is the significance of this statistic?
The number of revolutions per minute (RPM) is one of the basic factors determining the speed of the drive. 10,000 rpm represents good performance (15K rpm is the best available).
What sort of device could you use to expand the storage capacity of a smartphone?

How is a Windows library different from a folder?

What type of address identifies a network interface in the context of the local network segment only?
A Media Access Control (MAC) address.
What type of connector would you use for an external hard drive to connect to a Windows PC?
USB. Firewire, eSATA, or Thunderbird are also possible but not nearly so popular. Most drives are now USB3 or USB3.1. Note that you can plug a USB3 drive into a USB2 port, so long as you have a USB3 device cable.
In Windows, you can access data via letter-labeled "drives." Do these correspond exactly to physical disks?
Not necessarily in the case of hard disks, which can be configured with multiple partitions, each of which can be assigned a drive letter. Optical drives and flash memory cards cannot be partitioned however.
If you have made changes to a file and want to keep both the original file and the modified version, what command should you use?
Save As.
What is a WAN?
A Wide Area Network (WAN) connects sites in different geographic locations. WANs usually make use of telecommunications and service provider networks rather than being directly operated by the network administrators.
What type of device is used to transfer packets between different networks?
A router.
