A snowflake schema is characterized by a highly normalized structure, where dimension tables are normalized into multiple related tables.

An Object-Relational Database combines features of both relational and object-oriented databases.

A data mart is a subset of a data warehouse, often focused on a specific business line or team.

Normalization in data warehousing aims to reduce data redundancy and improve data integrity, although denormalization is often used for performance.

ETL stands for Extract, Transform, Load, which is the process of moving data from source systems into a data warehouse.

1110 is the largest binary number among the options.

Flip-flops are commonly used to implement binary counters, as they can store and toggle states.

A full adder can be implemented using AND, OR, and NOT gates.

Inductors oppose changes in current due to their property of inductance.

A 555 timer can be configured in astable, monostable, and bistable modes.

The 555 timer can be used in monostable, astable, and bistable configurations, but not quadrastable.

A voltage follower is achieved using a non-inverting configuration of an op-amp.

The voltage follower configuration provides the highest input impedance.

An Up/Down counter can count in both directions, either incrementing or decrementing the count.

A transaction is a sequence of operations that are treated as a single unit of work, ensuring data integrity.

A FET (Field Effect Transistor) is a voltage-controlled device that operates by applying voltage to the gate.

GAL stands for Generic Array Logic, which is a type of programmable logic device that allows for the implementation of combinational logic.

SPDT stands for Single Pole Double Throw, meaning it can connect one input to one of two outputs.

A zero-crossing detector identifies points where the signal crosses the zero voltage level, which is useful for timing and synchronization.

An analog signal is characterized by continuous values that can represent a range of information.

FPGAs consist of configurable logic blocks and interconnects that allow for flexible circuit design.

After a long time in a DC circuit, an inductor acts as a short circuit.

The Nyquist theorem states that a signal can be accurately reconstructed if it is sampled at a rate greater than twice its highest frequency.

In the 'off' state, a thyristor blocks current flow until triggered by the gate.

A multiplexer is commonly used in MSI logic circuits for routing data from multiple inputs to a single output.

A single transistor is not classified as MSI; it is a basic electronic component, while the others are MSI devices.

According to De Morgan's Theorem, NOT (A OR B) is equivalent to NOT A AND NOT B.

The Ex-OR gate is also known as the XOR gate, which outputs true when inputs differ.

.txt is the file extension for plain text files.

JPEG (Joint Photographic Experts Group) is a commonly used method of lossy compression for digital images.
