The invention of computers has totally changed the daily life activities of human beings and the world as it is one of the greatest achievements. When invented, they are of room size, and within a span of 100 years, they are on our laps and became very handy. The major inventions like transistors, vacuum tubes in the electronics field in the 1950s are the main reason which helped to reduce the size. Later on, VLSI and Nanotechnology brought a revolution which leads to the increase in the memory and fastens the processing speed of the computer. There is a question that did anybody ever thinks why can’t we find all these tiny and minute electronic components but only a small box with a power button and CD drive disk. It is because they are shield inside the CPU of the computer with a case.
The case of equipment which covers all the components like motherboard, hard disk, fan, power supply unit, the floppy disk is the computer tower. It is available in the desktop systems. Inside the tower, all the electronic components are in such organized way that they are compact enough and at the same time, the power button and CD drives points are easily accessible. These towers are available in various sizes and shapes made up of the variety of materials. The size of the tower depends on the number of components which we fix inside. The type of equipment used can be steel, aluminum, plastic. One side of the case can be removable which helps to look at the components fixed inside. Among all the elements set, majorly accessed one from outside view is the power button
The computer power supply unit is inside the tower which is the primary component of the network. When no power, then no access to the system. It is an electronic device, which supplies the electric power essential for the rest of the components to function properly inside the tower. The AC, i.e., alternate current, the power which is generally of 250 watts enables to step down AC power to DC, i.e., direct current, a power which suffices for the operation of the electronic components. To cool this unit, the electric fan fixed inside the case can be very helpful.
However, these groups need the continuous power supply for uninterrupted functioning of the computer. Nowadays, people come across laptops and notebooks which even work during the power of which are the results of technological advancements. They have batteries inside the systems to back up the power. Nevertheless, these batteries won’t last lifelong. So again the cycle repeats, and they need to have charging continuously to operate. That is the reason, many desktops and in many companies where there is the massive usage of computers, generators, and UPS (unit power supply) installation is mandatory.Comments Off on Technology and Development
