The Evolution, Design and Impact of the Personal Computer (PC) Personal computers have evolved from large and slow machines to the high-powered microcomputers with ever increasing capabilities available today. New technologies and superior components have been developed over time resulting in smaller, faster, more efficient designs.
The revolutionary age of personal computers began in the early 1970’s with kit computers. These were built by entrepreneurs, hobbyists, students, and other individuals with a passion for the emerging technology. The advent of the microprocessor helped make this possible. Coupled with newly developed software these devices became increasingly useful and popular (Computer History Museum).
In 1974 Henry Edward

Business transactions are processed through computers where once pencil, paper and arithmetic were the only way. Advertisements on the internet help pull in many thousands of customers and millions of dollars in revenue to everything from small local businesses to multibillion dollar international corporations. The internet and social media has brought individuals together and made the world accessible to anyone. Current news, knowledge and education is now within reach of the multitudes from their homes, jobs and institution of education.
Computer science has led to quantum leaps in the theoretical disciplines. For instance, the proving of the Kadison-Singer Conjecture by Adam Marcus, Daniel A Spielman and Nikhil Srivastava in 2013. Also on site data analysis is now possible thanks to more portable PC’s and the rapidly expanding technologies related thereto. Science and technology are greatly impacted by each other, and computer science plays an increasingly realized role in

It is difficult or impossible to modify data stored in ROM. A programmable form of ROM called BIOS (Basic Input/output System) is a chip located on all motherboards allowing for basic setup of the computer (Computer Hope).
The Hard Drive is a data storage device best described as the long-term memory of a PC. It reads and records data as a series of bits represented by particles organized in a longitudinal fashion in a magnetically sensitive coating on the surface of spinning platters. These particles or bits are in either a 0 or 1 state and are read as binary. In fact, the term bit is a portmanteau of binary digit. The platters, generally one to four, are hermetically housed.
Buses are communication systems responsible for connecting and transferring data between the components of the motherboard. The function of buses is to reduce the number of pathways and speed up the transfer of data. They may be wired in either a multi-drop or daisy chain
