The Ongoing Transition Of Hardware

Before the 1970s the word "hardware" usually meant one of two things: the beautiful chrome handles on your new dresser and the kitchen cabinets, or the hammer, saw, and nails that you purchased at the local hardware store. Then came the computer boom! Hardware took on a new meaning! If all the programming that made a computer work were called software, then the hard box and its components took on the name of hardware.

Hardware became a massive, competitive industry that expanded beyond the largest, most powerful dreams of the 1970s. Made of hundreds of various components that can be added, disconnected or exchanged depending on which features you want, the computer has a versatility that is limited only by ones imagination, budget and, realistically, one's patience.

Cisco Certification: Don't Overreact To Exam Version Changes

Whenever a Cisco exam version changes, there's always a lot of chatter about it on the web. The CCNA exams are no exception.

Do not let this happen to you.

Is There a Waterproof Solar Charger?

Many people using solar chargers want to know if there is a waterproof solar charger available. Most of these people who like to use their solar chargers while at the beach are afraid that the water splashing around will ruin their chargers. Solar chargers are very durable and most can withstand the normal splashing that occurs at the beach.

The sun power that is used to operate a solar charger is a great way for people at the beach to keep their electrical devices running. Because solar chargers are meant to be used outside, they are naturally waterproof. They are made to withstand rain and other natural weather that may occur around them.
