Because latency is so important, the HTTP protocol and HTML markup language were invented to reduce the rendering time of hypertext over the internet.

Because TCPMUX allows someone to use any service only by accessing port number 1, the protocol makes it difficult to apply traditional port-based firewall rules that block access from certain or all hosts to specific services.

Because only one guard can be chosen, a guarded choice command in general effectively requires a kind of two-phase commit protocol or perhaps even a three-phase commit protocol if time-outs are allowed in guards ( as in Occam 3 ).

Because the power to run the DRLs must be produced by the engine, which in turn requires burning additional fuel, high-power DRL systems increase CO < sub > 2 </ sub > emissions sufficiently to affect a country's compliance with the Kyoto protocol on greenhouse gas emissions.

Because it is a binary protocol, it is well-suited to sending binary data without any need to extend the protocol with attachments.

Because Bessel's equation becomes Hermitian ( self-adjoint ) if it is divided by x, the solutions must satisfy an orthogonality relationship for appropriate boundary conditions.

Because water is incompressible and must remain within the confines of the bucket, this outward movement increases the depth of water at the larger radius, increasing the height of the surface at larger radius, and lowering it at smaller radius.

Because society needs people to do computing well, we must think of computing not only as a profession but also as a discipline.

Because the number of days in the tropical year is not a whole number, a solar calendar must have a different number of days in different years.

Because the islands cannot produce enough goods to support the population, about 90 % of their food and consumer goods must be imported.

Because acids were thought at the time to necessarily contain oxygen, a number of chemists, including Claude Berthollet, suggested that Scheele's dephlogisticated muriatic acid air must be a combination of oxygen and the yet undiscovered element, and Scheele named the supposed new element within this oxide as muriaticum.

Because the functions f ( g ( x )) and x are equal, their derivatives must be equal.

Because only a fraction of the cells in a tumor die with each treatment ( fractional kill ), repeated doses must be administered to continue to reduce the size of the tumor.

Because compressed data must be decompressed to be used, this extra processing imposes computational or other costs through decompression, this situation is far from being a free lunch.

Because DOM supports navigation in any direction ( e. g., parent and previous sibling ) and allows for arbitrary modifications, an implementation must at least buffer the document that has been read so far ( or some parsed form of it ).

Because of this a quadratic equation must contain the term, which is known as the quadratic term.

Because a phocid mother's feeding grounds are often hundreds of kilometers from the breeding site, she must fast while lactating.
