Study Notes
Ubiquitous Computing
- Refers to the integration of computers and technology into nearly every aspect of daily life.
Authentication Systems
- Systems that permit access only to authorized individuals using methods like access cards or biometric scans (fingerprints, hand scans).
Data
- Represents raw, unorganized facts that are manipulated during processing.
Communications
- Often regarded as the fifth primary operation in computers, alongside four core operations.
Third-Generation Computers
- Marked by the introduction of integrated circuits (ICs).
Communications Components
- Example: Routers, which facilitate communication between devices and networks.
Boot Process
- Involves loading a portion of the operating system to prepare the computer for use.
Cloud Software
- Can run directly from the Internet via web pages without needing local installation.
System Software and Microsoft Word
- Microsoft Word is an example of application software, not system software.
Role of Systems Analysts
- Misconceptually thought to handle daily operations like maintaining systems; they focus more on system design and analysis.
