thirst for extensive knowledge on electronics rose again. I did some online courses to get a better understanding but I knew that was not enough. As a lecturer, I also took theoretical courses on Microprocessor & Interfacing, Computer Programming & application, Signals & Systems and Electronics-I. This helped me to gain an in depth knowledge in each of these subjects and develop my communication skills as well. I also did two short course training on Radar Engineering and Avionics Engineering…
Chapter 1 Introduction One of the most striking technological developments of the last fifty years has been the emergence of digital technology as a powerful force in our lives. For many of us, this technology is embodied in the digital computer, which has evolved to be an essential tool for our work as well as our personal needs. In 1951, when the first commercial electronic digital computer, a UNIVAC I, was delivered to the U.S. Bureau of the Census, computers were essentially unknown to most…
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…
of the computer. Processors are used in all types of computers The CPU plugs into something known as a CPU socket which is located on the mother and this socket delivers electrical contact to the microprocessor and to something known as a printed circuit board. In the case of chips with have a big number of pins land grid array sockets or zero insertion force sockets are used as a alternative. CPU speeds are measured in hertz or in giga hertz. Clock speed is basically the measure of how many…
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…
