according to Einstein, nothing can travel faster than this universal speed limit.

light 

units: m/s

100

This logic gate outputs true only when both inputs are true.

Binary System

100

This everyday technology relies on satellites to tell you exactly where you are on Earth.

GPS

200

This device connects multiple devices within the same local network and forwards data based on MAC addresses.

Switch

200

In science fiction, this hypothetical tunnel through space could connect two distant points instantly.

Wormhole

200

This combinational circuit selects one of many input signals and forwards it to a single output line based on select inputs.

MUX

200

When you watch live TV from another country, this type of satellite is often making it possible.

Communication Satellite

300

This layer of the OSI model is responsible for routing packets between networks.

Network layer

300

Due to this effect, time moves slower for astronauts traveling at very high speeds compared to people on Earth.

time dilation 

300

This combinational circuit converts binary data into a one-hot output.

Decoder

300

Satellites stay in orbit because their forward motion balances this force pulling them toward Earth.

gravity 

400

This protocol ensures reliable, ordered, and error-checked delivery of data between applications.

TCP

400

This theory by Einstein explains how gravity can bend space and time.

general relativity 

400

This memory element is implemented using cross-coupled NAND or NOR gates and forms the basis of most sequential circuits.

SR-Latch

400

This region of space around Earth is crowded with old satellites and debris, creating a growing collision risk.

space junk (orbital debris)

500

This algorithm is used by routers to find the shortest path between nodes, famously used in link-state routing protocols.

Dijkstra's Algorithm

500

Near a black hole, this boundary marks the point beyond which nothing—not even light—can escape.

event horizon 

500

If A = 0 and B = 0

What is the output of this circuit?

0
