What are the benefits of building redundancy into a network?

By providing additional or alternate equipment, or planning alternate network paths, you ensure availability in the case of device or path failure. Building in redundancy gives you a network failover to avoid an extended outage (AKA, disaster recovery).

the answer to your question would be something called hertz. the unit of measurement called a hertz, which is one cycle per second, is used to measure clock speed. within one cycle, your computer processes, refreshes, or updates itself to the changes that it is going through. in the case of computer clock speed, one hertz equals one tick per second. the clock speed of computers is usually measured in megahertz (mhz) or gigahertz (ghz)
