Study Notes
Network Fundamentals
- The primary purpose of RAID (Redundant Array of Independent Disks) technology is to provide data redundancy and improve data reliability.
- PAN stands for Personal Area Network, which is a network that connects devices within a limited area, such as a home, office, or public hot spot.
Operating System
- The main function of an Operating System (OS) is to manage computer hardware resources and provide common services to computer programs.
Network Types
- A Wide Area Network (WAN) may span cities or countries, connecting devices over a large geographical area.
Network Security
- The function of a firewall in a network is to block or allow incoming and outgoing network traffic based on predetermined security rules.
Network Topology
- Routers play a crucial role in network topology by connecting multiple networks and routing traffic between them.
- In a star network configuration, the network topology impacts performance, as all devices connect to a central hub or switch, which can become a single point of failure.
Software Architecture
- The term 'client-server' in software architecture refers to a model where a client requests resources or services from a server, which provides the requested resources.
Healthcare Information System
- The main focus of the course on Healthcare Information System is to manage and coordinate healthcare information and services.
Information System Components
- The basic components of an Information system are hardware, software, data, and people.
Computer Terminology
- 1 terra corresponds to 1 trillion bytes of data.
- Giga Hertz (GHZ) refers to a unit of frequency, where 1 GHZ is equal to 1 billion cycles per second.
