The calcium content of phosphorus-containing foods may also matter, and may mitigate potential problems. In fact, dairy foods (high in both phosphorus and calcium) lower blood pressure, which is why they are an integral part of the DASH (Dietary Approaches to Stop Hypertension) diet.he calcium content of phosphorus-containing foods may also matter, and may mitigate potential problems.

This originally pertained to radio waves and sound waves, but is now commonly used to measure the speed of a computer processor (the number of hertz is equal to the number of clock ticks that a processor will have in one second).
CPU. You may have heard the term clock speed.. It refers to the speed of your computer's central processing unit or CPU. Often called the brain of the computer, the CPU processes the instructions that programmers write when they create applications.ardware makers measure a CPU's clock speed using a unit called gigahertz. A CPU running at 3GHz processes data faster than one running at 1GHz. The speed at which data flows from the CPU to applications also affects the computer's speed. Computer makers call that the bus speed.
