9. API – Application Programming Interface
- Definition: A set of protocols and tools for building software and applications.
- Importance: APIs enable different software to communicate with each other.
- Usage: Companies integrate third-party services into their platforms through APIs.
10. RAID – Redundant Array of Independent Disks
- Definition: A technology that combines multiple disk drives to improve performance and/or data redundancy.
- Importance: RAID setups increase data security and system uptime.
- Usage: Businesses with critical data requirements often deploy RAID setups.
11. UPS – Uninterruptible Power Supply
- Definition: Provides emergency power to electrical devices in case of power failure.
- Importance: UPS devices are essential for preventing data loss and hardware damage during power outages.
- Usage: Data centres use UPS to maintain operations during power interruptions.
12. MAC – Media Access Control
- Definition: A hardware identification number that uniquely identifies each device on a network.
- Importance: Used for network management and security measures.

13. LAN – Local Area Network
- Definition: A network that connects computers within a limited area such as a building or campus.
- Importance: LANs enable efficient internal resource sharing.
- Usage: Many companies set up LANs to share files and peripherals like printers.
14. WAN – Wide Area Network
- Definition: A network that covers a large geographic area.
- Importance: WANs enable remote branches to communicate as if they are on the same local network.
- Usage: Multinational companies often rely on WANs for global operations.
15. DNS – Domain Name System
- Definition: The system that translates human-friendly domain names into IP addresses.
- Importance: Without DNS, users would have to remember IP addresses to access websites.
- Usage: Companies often have internal DNS servers for better network management.
16. NAT – Network Address Translation
- Definition: A technique for remapping IP addresses in the traffic from one network to another.
- Importance: NAT enhances security and simplifies network management.
- Usage: Used in routers to enable multiple devices on a local network to share a single public IP address.
17. VoIP – Voice over Internet Protocol
- Definition: Technology that allows voice communications and multimedia sessions over the internet.
- Importance: Offers a cost-effective and flexible alternative to traditional telephony.
- Usage: Businesses are increasingly adopting VoIP systems for their communications needs.
18. MPLS – Multi-Protocol Label Switching

- Importance: MPLS increases network speed and performance.
- Usage: Often used in high-performance telecommunication networks.
19. IaaS – Infrastructure as a Service
- Definition: Online services that provide high-level APIs used to dereference various low-level details of underlying network infrastructure.
- Importance: IaaS allows businesses to scale and descale quickly according to their needs.
- Usage: Start-ups often use IaaS to avoid the expense and complexity of buying and managing physical servers.
20. PaaS – Platform as a Service
- Definition: A category of cloud computing services that provides a platform to develop, run, and manage applications.
- Importance: PaaS simplifies the development process, saving time and effort.
- Usage: Companies often use PaaS for application development as it removes the complexities of software maintenance.
21. SaaS – Software as a Service
- Definition: A software licensing and delivery model where software is accessed via the internet.
- Importance: SaaS eliminates the need for organisations to install and run applications on their computers.
- Usage: Many CRM and ERP solutions are now offered as SaaS, allowing for easier scalability and lower upfront costs.
