Target entity: PCI bus Context triple: [VESA Local Bus, successor, PCI bus]
-
A.
PCI-X
PCI-X is an older high-speed parallel computer expansion bus standard used mainly in servers and workstations before being superseded by PCI Express.
-
B.
PCI Express
PCI Express is a high-speed serial computer expansion bus standard used to connect components like graphics cards, SSDs, and network cards to a motherboard.
-
C.
VESA Local Bus
VESA Local Bus was a high-speed expansion bus standard for IBM-compatible PCs in the early 1990s, designed primarily to improve graphics and overall system performance by providing a faster connection to the CPU than the older ISA bus.
-
D.
Multibus
Multibus is an early Intel-developed computer bus standard widely used in 1980s workstations and embedded systems for modular expansion and peripheral connectivity.
-
E.
PCI-SIG
PCI-SIG is an industry consortium that defines and maintains the PCI Express (PCIe) and related peripheral interconnect standards for computers and electronic devices.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: PCI bus Description of subject: The PCI bus is a widely adopted computer expansion bus standard that provides a high-speed, processor-independent interface for connecting peripheral devices to a motherboard.
