Minicomputer In the s and s, more and more departments started to use cheaper and dedicated systems for specific Parts of the computer like process control and laboratory automation.
Supercomputer A supercomputer is superficially similar to a mainframe, but is instead intended for extremely demanding computational tasks. The term supercomputer does not refer to a specific technology.
Rather it indicates the fastest computations available at any given time. Supercomputers are fast but extremely costly, so they are generally used by large organizations to execute computationally demanding tasks involving large data sets. Supercomputers typically run military and scientific applications.
Although costly, they are also being used for commercial applications where huge amounts of data must be analyzed. For example, large banks employ supercomputers to calculate the risks and returns of various investment strategies, and healthcare organizations use them to analyze giant databases of patient data to determine optimal treatments for various diseases and problems incurring to the country.

October Hardware upgrade[ edit ] When using computer hardware, an upgrade means adding new hardware to a computer that improves its performance, adds capacity or new features.
For example, a user could perform a hardware upgrade to replace the hard drive with a SSD to get a boost in performance or increase the amount of files that may be stored.
Also, the user could increase the RAM so the computer may run more smoothly. The user could add a USB 3. Performing such hardware upgrades may be necessary for older computers to meet a programs' system requirements. Sales[ edit ] This section needs to be updated.

Computer recycling Because computer parts contain hazardous materials, there is a growing movement to recycle old and outdated parts. According to the EPA these e-wastes have a harmful effect on the environment unless they are disposed of properly.
Making hardware requires energy, and recycling parts will reduce air pollutionwater pollution, as well as greenhouse gas emissions. Legislation makes it mandatory to recycle computers through the government approved facilities. Recycling a computer can be made easier by taking out certain reusable parts.
Toxic computer components[ edit ] The central processing unit contains many toxic materials. It contains lead and chromium in the metal plates. Resistors, semi-conductors, infrared detectors, stabilizers, cables, and wires contain cadmium.
The circuit boards in a computer contain mercury, and chromium.
When e-waste byproducts leach into ground water, are burned, or get mishandled during recycling, it causes harm. Health problems associated with such toxins include impaired mental development, cancer, and damage to the lungs, liver, and kidneys. Different companies have different techniques to recycle a wire.Uniquely focused on computers and related products, Micro Center offers more computers and electronic devices than any other retailer.
