Mobile Device Synchronization

Question 1

For what types of data is synchronization useful?

Answer 1

• email
• applications
• contacts
• calendar
• pictures and video
• music
• webpage bookmarks
• passwords
• documents
• etc

Question 2

What are the software requirements of an application referring to?

Answer 2

Refers to the minimum hardware capabilities required to run said application.

Question 3

What is memory in a computer and how is its performance measured?

Answer 3

• Refers to Random Access Memory (RAM)
• Interacts with the CPU to store data and instructions for calculations used to run different applications and functions
• Measured in Bytes. Most modern RAM offers Gigabytes to Terabytes of memory
• 1024 Bytes = 1 Kilobyte (1 KB)
• 1024 KB = 1 Megabyte (1 MB)
• 1024 MB = 1 Gigabyte (1 GB)
• 1024 GB = 1 Terabyte (1 TB)

Question 4

Describe how cloud synchronization works.

Answer 4

• Remote data centers act as central repositories for storing application data. Any device with access to that cloud or application account is able to edit data for that application
• Used for email, messaging, calendars, photos, music and more

Question 5

What is video in a computer and how is its performance measured?

Answer 5

• Refers to the Graphic Processing Unit (GPU)

- RAM for video measured in Bytes to Megabytes to Gigabytes for most GPUs

Question 6

What is SSO and how is it beneficial?

Answer 6

• Single Sign On (SSO)
• Allows access to multiple sites using the credentials from an SSO service such as Google, Facebook or Microsoft
• Reduces the need to create and remember multiple accounts and credentials across multiple sites

Question 7

What components are most typically referenced in the software requirements of an application?

Answer 7

• CPU
• Memory
• Video
• Monitor: some applications may require a specific monitor display resolution

Question 8

How is CPU performance measured?

Answer 8

• Measured in Hertz (Hz) where each Hz is a processor calculation per second
• Most modern processors are capable of multiple Gigahertz speeds where each Gigahertz represents 1 billion calculations per second
• 1 Gigahertz = 1000 Megahertz = 1,000,000,000 Hertz
• 1 Megahertz = 1,000,000 Hertz

Question 9

What monitor specifications might an application require?

Answer 9

• 720p to 1080p

- 4k

Question 10

Describe how bluetooth synchronization works.

Answer 10

• Typically limited to functions like syncing contacts, phone calls, and music
• For example, playlists and contact information from a phone can be synced to a cars audio system over bluetooth

Question 11

When it comes to user data, what is synchronization?

Answer 11

Changes made to data on one device are propagated to all devices with access to that data.

Question 12

Describe how direct synchronization works.

Answer 12

• Facilitated by use of a direct cable connection between two devices, most often a computer and smartphone.
• Once the connection is made the user can backup data or otherwise transfer files from one device to the other

Question 13

What methods are most commonly used to synchronize data?

Answer 13

• Cloud
• Direct
• Bluetooth
