The growth and development of technology has expanded significantly over the past few years, and is still expanding. This is particularly so in most middle-class to upper-class families that can afford to own various electronic devices. Due to the fast pace of this current generation, adults are not the only ones with access to inventions of technology; most children belonging to these classes of families possess their own personal devices, and this is not always a good thing. Thus parents, of…

To overcome the limitations of manual switching; automatic exchanges, having Electro-mechanical components, were developed. Strowger exchange, the first automatic exchange having direct control feature, appeared in 1892 in La Porte (Indiana). Though it improved upon the performance of a manual exchange it still had a number of disadvantages, viz., a large number of mechanical parts, limited availability, inflexibility, bulky in size etc. As a result of further research and development, Crossbar…

All of my life I have enjoyed using computers, it was until recently that I had wanted to be able to fix them, to build them. It is a major dream of mine now that I am older and more readily prepared for such complex thinking and analyzing skills that are required when being a computer repair technician. Computers, how they work, how to fix them, is all in a day's work for a computer repair technician. They jump to the rescue to fix and pull a computer back from the brink of death, whether it…

Reading "History of the Personal Computer" It was a pleasant spring morning to sit out on the porch and read chapter 3 and 4 from the course material. Much of this history I had either lived through in the 70's or been exposed to at the Intel Museum's Santa Clara California. As I understand it, the Museum was started as a place to put all of Gordon Moore stuff. In chapter 4 the story of Wazniaks and Jobs early years, was also amusing. I read the same story about the blue box in the early…

Central Processing Unit (CPU) which is made up of three major components, the arithmetic/logic unit (ALU), the control unit (CU) and memory by combining the ALU and CU together you get the CPU), (Englander, I. 2014). The arithmetic/logic unit holds data temporary and where calculation are processed the control units controls and deciphers the execution command and follow the instruction that goes with the sequence of actions. The control unit determines the particular instruction to be…

If you don’t know anything about central processing units, then you should probably go sky diving and jump without a parachute. Today, we will deliberate about the revolutionary technology that is being brought to us by AMD and Intel. Before we start, I would like to clear any confusion by going over terms that should be discerned and understood. Overclocking is the process that involves virtually increasing the speed/frequency of a processor. Cores and threads are the exact same thing, and they…

1. List and describe 3 key points made in the video “The Story of Electronics.” • Designed for the dump – products are designed to be hard to repair, breaks easily, and difficult to upgrade. These items led to more devices going to the landfill since it is cheaper to replace them. • Product Takeback – Companies would be responsible for devices and products they produce including their disposal. This could lead to much better designs of the product and devices, which might last longer, have…

Swagtron line of electric skateboards, the Voyager Longboard. The Voyager is one of the most powerful electric longboards on the market! Featuring dual 350 watt motors can blast you to a full 30 mph (though for safety reasons the governor limits the board to 15mph). The Voyager can cruise for up to 15 miles on one charge and can handle weight up to 330lbs. The electric longboard runs on two 36V Lithium Ion Phosphate batteries, which last longer and are safer than your standard lithium-ion…

different point. Companies have witnessed robbery attack, terrorist attack, shooting rampage by disgruntled employees or students in an institution of learning. It was also vividly mentioned in this chapter that if any security measures such as closed-circuit TV (CCTV) surveillance, security guards, intrusion detection systems (IDSs) failed, then of course the fault is from a human being considered as the weakest link in information security. This chapter also noted that people did not embrace…

In many eyes of America, what keeps the Country strong is faith, strength and guns. Faith to keep us mentally sane, strength to keep us strong, and guns to keep our military safe. What in between the lines of those three major things, keep everything glued together? Police, the comfort we feel from the Police Force, and Security. How would we feel as a country without that comfort level from the Police Force? The same way the Police would feel without being able to have Surveillance Cameras,…
