Glossary of terms
ID, short for identification, refers to a unique set of characteristics or attributes that distinguishes an individual, object, or entity from others. Here’s a more detailed definition, along with the main features and scope of ID:
ID is a unique identifier or a combination of identifiers that serves to establish and verify the identity of an individual, object, or entity within a specific context or system.
1. Uniqueness: Each ID should be unique and distinct from others, ensuring that it can unambiguously identify a particular individual, object, or entity.
2. Persistence: An ID should remain constant and unchanging over time, allowing for consistent identification and tracking of the associated entity.
3. Verifiability: The ID should be verifiable through authorized means, such as documentation, biometric data, or other authentication methods, to confirm the claimed identity.
4. Context-specific: IDs are often designed and used within specific contexts or systems, such as government-issued identification documents, corporate employee IDs, or online user accounts.
1. Personal Identification: IDs are widely used to identify individuals, such as national ID cards, passports, driver’s licenses, social security numbers, or biometric identifiers (e.g., fingerprints, iris scans).
2. Object Identification: Physical objects can be assigned unique IDs, such as serial numbers for electronic devices, vehicle identification numbers (VINs) for automobiles, or barcodes/QR codes for inventory tracking.
3. Digital Identification: In the digital realm, IDs are used for various purposes, including user accounts (e.g., email addresses, usernames), digital certificates, and unique identifiers for data records or files.
4. Access Control: IDs play a crucial role in controlling access to physical spaces (e.g., buildings, rooms), digital resources (e.g., computer systems, applications), or restricted areas based on authorized identities.
5. Tracking and Traceability: IDs enable the tracking and traceability of individuals, objects, or entities throughout various processes, systems, or supply chains, facilitating accountability and audit trails.
6. Authentication and Authorization: IDs are fundamental for authentication (verifying claimed identities) and authorization (granting or denying access to resources based on identities and associated permissions).
The scope of ID encompasses a wide range of applications across various domains, including government, finance, healthcare, security, logistics, and many others, where accurate identification and verification of identities are essential.

Businesses need reliable and efficient management of information flows to operate. Data collection, storage, and management require a well-developed infrastructure with workstations, database servers, storage nodes and networks, engineering networks, and data transmission networks. Building such an infrastructure requires serious start-up investments and ongoing maintenance costs. Using cloud network technology eliminates most of these problems. So what is cloud technology?
