This protocol is used to send web pages over the internet.
HTTP
according to Einstein, nothing can travel faster than this universal speed limit.
light
units: m/s
This logic gate outputs true only when both inputs are true.
Binary System
This everyday technology relies on satellites to tell you exactly where you are on Earth.
GPS
This device connects multiple devices within the same local network and forwards data based on MAC addresses.
Switch
In science fiction, this hypothetical tunnel through space could connect two distant points instantly.
Wormhole
This combinational circuit selects one of many input signals and forwards it to a single output line based on select inputs.
MUX
When you watch live TV from another country, this type of satellite is often making it possible.
Communication Satellite
This layer of the OSI model is responsible for routing packets between networks.
Network layer
Due to this effect, time moves slower for astronauts traveling at very high speeds compared to people on Earth.
time dilation
This combinational circuit converts binary data into a one-hot output.
Decoder
Satellites stay in orbit because their forward motion balances this force pulling them toward Earth.
gravity
This protocol ensures reliable, ordered, and error-checked delivery of data between applications.
TCP
This theory by Einstein explains how gravity can bend space and time.
general relativity
This memory element is implemented using cross-coupled NAND or NOR gates and forms the basis of most sequential circuits.
SR-Latch
This region of space around Earth is crowded with old satellites and debris, creating a growing collision risk.
space junk (orbital debris)
This algorithm is used by routers to find the shortest path between nodes, famously used in link-state routing protocols.
Dijkstra's Algorithm
Near a black hole, this boundary marks the point beyond which nothing—not even light—can escape.
event horizon
If A = 0 and B = 0
What is the output of this circuit?
0
This famous satellite was the first artificial object sent into space by humans in 1957.
