vi tinh

Một viên đá vi tinh được đặt trên bàn trong phòng thí nghiệm địa chất.

Definition

1. Noun:
   • Microlite: A very small crystal, typically found in igneous rocks, visible only under a microscope. This is a specialized term in geology and mineralogy.
   • Microcomputer: A dated but occasionally used term for a personal computer or desktop computer, derived from the Sino-Vietnamese roots "vi" (micro) and "tinh" (intelligent/calculation). This usage is now largely archaic.

Usage Examples

• Noun (Geology):

  • Các nhà địa chất phát hiện vi tinh trong mẫu đá núi lửa. (Geologists discovered microlites in the volcanic rock sample.)
  • Đá vi tinh có cấu trúc hạt rất mịn. (Microlitic rock has a very fine-grained structure.)

• Noun (Computing, Archaic):

  • Hồi những năm 90, gia đình tôi mua chiếc vi tinh đầu tiên. (In the 90s, my family bought our first microcomputer.)

Advanced Usage

• The term is highly technical in its primary geological meaning. In modern computing contexts, it has been almost entirely replaced by terms like máy tính (computer) or máy vi tính (a slightly more common but also dated term for personal computer).

Variants and Related Words

• Đá vi tinh (n): Microlitic rock; rock containing microlites.
• Máy vi tính (n): An older compound term for a personal computer.

Synonyms

• Microlite (in geology): crystallite, microcrystal.
• Microcomputer (in computing, archaic): personal computer, desktop computer, PC.

Notes on Usage

• "Vi tinh" is a low-frequency word. Learners are most likely to encounter it in specialized scientific texts about geology. Its computing meaning is obsolete and rarely used in contemporary Vietnamese.
