20
Q

What capability does having a multi-core CPU grant a user?

A

the ability to execute several programs simultaneously

21
Q

Clock speed determines how ___ the CPU…

A

How fast the CPU is able to fetch and execute instructions

22
Q

Some applications may require multiple-core CPUs and a minimum clock speed. T or F?

A

True

23
Q

What are some of the forms that an external hardware token can take? (4)

A
  1. USB tokens
  2. key fobs
  3. wireless Bluetooth
  4. RFID tokens
24
Q

What is an external hardware token?

A

a small hand-held device used as a security tool to identify/authenticate a network or computer

25
Q

How does an external hardware token work?

A

It prevents users who don’t have the token from running the software

26
Q

What are the 3 types that hardware tokens are categorized as?

A
  1. Connected (inserted into a reading device, or touch a scanner)
  2. Contactless (wireless using Bluetooth or RFID)
  3. Disconnected (app on a smartphone w/ one-time access code)
27
Q

What are 2 things you can do if you have limited space but want to install an application?

A
  1. Remove seldom-used applications
  2. Run Disk Cleanup
28

Q

What are 4 OS issues that can prevent an application from running?

runs in, made for, requires a, not compatible

A
  1. The app runs in 64-bit mode only (no 32-bit systems)
  2. app made for a newer version of the OS
  3. app requires a newer version of DirectX 3D
  4. app is not compatible with the current OS version
30
Q

Can Win 10 and Win 11 run applications designed for Win7 or greater?

A

Yes they can run nearly any application (any app problems are really old apps for like Windows XP)

31
Q

How do you solve compatibility issues with older applications?

A

Adjust the app’s compatibility settings via the compatibility tab in Properties (navigate to the location of the main .exe file)

32
Q

What version should you pick in the drop-down list when adjusting an app’s compatibility?

A

The version that came out around the same time that the application was released

33
Q

Can a 64-bit application run on a 32-bit OS?

A

No

34
Q

Can a 32-bit application run on a 64-bit OS?

A

Yes, but not as well as a 64-bit application would

35
Q

What’s the best solution to run legacy (32-bit) applications?

A

run them in a virtual machine or other emulator

36
Q

What are the 3 type of ways apps can be acquired?

A

provided primarily by the software repository associated with the publisher and distro in use

A

Linux uses a hybrid of local and network-based application installation processes

41
Q

How are mobile apps (Android, iOS) installed for corporate environments? (2)

A
  1. Mobile Device Management (MDM)
  2. Mobile Applications Management (MAM)
42
Q

What does it mean to mount an ISO file?

A

If you choose not to burn the ISO onto your own writeable disc, you can mount it in your OS as if it were a physical drive and the OS interacts with it as such

43
Q

What are 4 potential impacts you should review before installing an application?

A
  1. Impact to device (has access to hardware and software)
  2. Impact to network (require access, use up network resources)
  3. Impact to operation (benefits like communication speed, negatives like staff training and data usage and storage)

44
Q

How can you tell if an app is a desktop app or a Microsoft Store app when you uninstall it?

A

First, right-click it on the Start menu and uninstall ->

Desktop app = Programs and Features opens up to uninstall
Microsoft Store app = it’s immediately uninstalled

45
Q

What are 5 things to look at when choosing an app?

A
  1. 32-bit vs. 64-bit app
  2. Hardware requirements
  3. External hardware tokens
