Alexander Graham Bell made the first telephone call this day in 1876. Due to his significant start, today, communication and information is booming. Both businesses and homes are filled with an array of electronics -- from computers, printers and fax machines to high-end television sets and audio for entertainment. Every year, lightning alone damages 100,000 computers, costing $125,000,000. Add to that electrical spikes and surges, and the annual destruction reaches billions. The answer is good surge protection and occasional replacement. Surges (big and small) occur on all types of lines -- electrical, telephone and cable television. And delicate microchips are susceptible to them all. Besides computer and data, you'll need electrical, phone and cable ports. For more tips, visit our Web site at Onthehouse.com.
