Study Notes
Database and Persistence
- A database is needed for persistent data storage in scenarios where data needs to be retained even after the application or utility is closed, such as when a customer fills out an online form to order a product.
File Permissions
- To grant a user permission to view and change files but not change permissions, the NTFS permission "Modify" should be used.
Database Features
- A "report" is a database feature that provides a formatted, easy-to-read listing of the results of a query.
Security
- To improve the security of sensitive information on a device if it is lost or stolen, encryption should be used.
Digital Communication Media
- SMS (Short Message Service) is a digital communication media that does not require a connection to the internet.
Employee Internet Usage
- An employee handbook should cover topics such as internet usage, including policies on acceptable use, data protection, and security.
Troubleshooting
- The first step in troubleshooting an issue should be to identify the problem and then take steps to resolve it, such as uninstalling the last application or system update that was installed.
DisplayPort
- DisplayPort 1.4 has a greater maximum bandwidth than HDMI 2.0.
Data Types
- The best data type for a variable that will hold whole numbers and perform numeric operations is an integer.
Audio Processing
- The DSP (Digital Signal Processing) chip is responsible for processing audio input from a microphone and converting it into data.
Computer Systems
- Computer systems that are interconnected to share information with each other are called network clients.
