The article I wrote about summarize how computers have evolved. A few years ago, we would have never thought that a computer would look so sleek and sophisticated. There is one interesting thing that you need to note about computers. While it was initially launched, it took several years to evolve. But in the 1990s and especially in the new millennium, there has been a great deal of evolution in its design as well as its performance. Evolution of computers has been drastically and dramatic. Computers have been in the existence in the early 1950s, but people were not able to use them. When you mention the word computer most people only think of the Desktop Computer, but in reality computer start with our calculator. Our society needs computers to evolve to maintain the progression we’re experience as a result of our evolution. The first computers to be invented were very big, slow and time consuming with limited capabilities. Computers history and has gone through various stage as they evolve starting with the first computers, before first generation computers we had the ABACUS computers which were limited by their capabilities. To see how a PC works, let's start with the pieces that come together to make up the machine. The following are the components common to PCs in the order they're typically assembled: Case -- If you're using a laptop, the computer case includes keyboard and screen. For desktop PCs, the case is typically some type of box with lights, vents, and places for attaching cables. Motherboard -- The primary circuit board inside your PC is its motherboard. All components, inside and out, connect through the motherboard in some way.
Power supply -- Other than its CMOS, which is powered by a replaceable CMOS battery on the motherboard, every component in your PC relies on its power supply. Central processing unit (CPU) -- The CPU, often just called the processor, is the component that contains the microprocessor. That microprocessor is the heart of all the PC's operations, and the performance of both hardware and software rely on the processor's performance. Random-access memory (RAM) -- Even the fastest processor needs a buffer to store information while it's being processed. Drives -- A drive is a device
