Who uses a supercomputer?
Supercomputers were originally used in applications related to national security, including nuclear weapons design and cryptography. Today they are also routinely employed by the aerospace, petroleum, and automotive industries.
Why is superframe format used?
In telecommunications, superframe (SF) is a T1 framing standard. In the 1970s it replaced the original T1/D1 framing scheme of the 1960s in which the framing bit simply alternated between 0 and 1. Superframe is sometimes called D4 Framing to avoid confusion with single-frequency signaling.
How much does a super computer cost?

What industries and businesses use supercomputers?
Supercomputers contribute significantly to the oil, automobile, aero- space, and chemical and pharmaceutical industries’ ability to solve com- plex problems.
What are quantum computers used for?
Quantum computers are machines that use the properties of quantum physics to store data and perform computations. This can be extremely advantageous for certain tasks where they could vastly outperform even our best supercomputers.
What is a superframe in architecture?
skyscraper design In construction: Classification of structural systems. …have a low premium: the superframe. In this structure much of the building’s gravity load, and therefore its material, is brought to a diagonally braced superframe tube at the perimeter by interior transfer trusses of various configurations.
What is duration of superframe?
In a superframe (see Figure 20.9), a dedicated PAN coordinator transmits superframe beacons in predetermined intervals. These intervals can be as short as 15 ms or as long as 245 seconds. The time between two beacons is divided into 16 equal time slots independent of the duration of the superframe.
Which countries have supercomputer?
Since June 2020, the Japanese Fugaku is the world’s most powerful supercomputer, reaching initially 415.53 petaFLOPS and 442.01 petaFlops after an update in November 2020 on the LINPACK benchmarks….Top countries.

Which is the best example of a superframe?
One of the famous examples is the Shanghai Tower shown in Fig. 5.34. The other famous example is the HSBC headquarters in Hong Kong. A ZigBee router is responsible for routing data frames, route discovery, and route repair. The router can establish its own superframe and accept the requests from other devices to join the network.
How are beacons used in a superframe system?
The beacons are responsible for three significant purposes that can be sorted as ensuring synchronization among devices, identifying PAN infrastructure and defining structure of superframes. A superframe is employed in beacon-enabled mode to manage communication in the wireless channel.
Why does 802.22 BSS need superframe structure?
Explain why and in which situations neighboring 802.22 BSs need to synchronize their quiet periods for spectrum sensing. Mega frame structure (also known as superframe structure) is an ideal structural system for supertall buildings, as it can provide efficient rigidity against the lateral loads with minimum amount of structural materials [11].
How does a Zigbee Router establish a superframe?
A ZigBee router is responsible for routing data frames, route discovery, and route repair. The router can establish its own superframe and accept the requests from other devices to join the network. The request to establish the device as a router is given to the NWK layer by the APL layer using the NLME-START-ROUTER.request primitive.
