Lots of people decide to purchase utilized computers due to a tight budget, however they must not end up purchasing a showpiece rather than a working piece. This makes it extremely essential to evaluate the utilized computer system prior to buying it. Assessment can be done by the buyer himself offered he has some knowledge on computer systems and their parts. If not, he can get some assistance from their good friends or relatives who are great in evaluating computer systems.
The used computer’s physical parts need to be examined thoroughly. Primary step is to search for any damages and after that attempting to switch on and off. It ought to be done by the buyer or by his friend rather than viewing the computer sales individual do it as it will alert for any glitches. Examining needs to be done to discover if the used computer system has an initial variation of the operating software application without which the computer system is not worth purchasing. Manuals, licenses for software applications, discs and fonts should be agreed the computer. The operating system of the used computer system needs to work enough to run the needed applications of the purchaser. Some times the seller may sell an utilized computer along with utilized drive, scanners and printers and consist of the expense of them too. It is not wise to buy used scanner, printers or hard disk drive as they have peripherals with moving parts which wear and tear with the passage of time and also the cost of them can be subtracted making the rate of the utilized computer system even lower.
The speed of the main processing system needs to be inspected. If it is not up to the expectation of the purchaser, it needs to be learnt if the used computer system can be upgraded for enhancing the speed and performance. The entire hardware parts need to be inspected including the keyboard, speakers, screen, mouse and microphones. It ought to be if all the hardware components inside the computer system like the CD-ROM drive, sound card, variety of RAM sockets etc are if present or not and if present what are the elements in usage. Likewise it requires to be checked whether it has a provision for including various type of cards and so on
. If the purchaser has already got some computer system parts like the screen, printer and so on, the utilized computer which is purchased must work with them. Nowadays used Pentium devices and power PCs are offered at really low rate. It is not advised to buy an utilized computer system which is older. Also it is great to discover if the used computer system features a transferable guarantee or service, if so it is worth purchasing.
The buyer needs to not wind up overpaying as utilized computer systems diminish at a lightning speed. There are lots of online auctions, which can provide the idea of just how much individuals are prepared to pay for a used computer. Sadly, there is no reputed or impartial source for knowing the costs for used computer systems.

How Computers Contributed to Human Health
No doubt, computer is the greatest of all inventions. Computers are known for their speed, precision, and reliability. In addition, with the inception of World Wide Web, computers have played a pivotal role in our lives.
Besides other advantages of computers, these machines have revolutionized the way we used to deal with numerous healthcare issues. To know how computers contributed in the field of healthcare, just continue reading.
Computers help to Diagnose
Computers can collect the data more precisely and accurately. This feature of computers allows us to diagnose various diseases by calculating the data received through other machines like MRI, Xrays, and other testing facilities.
Telemedicine
Telemedicine is a way of providing healthcare facilities without physically reaching the patient. Here computers play an essential role in terms of diagnosis, exchange of information, prevention and treatment of the diseases.
In most of the cases, telemedicine provides the opportunity to communicate in real-time. Hence, doctors and patients can communicate through computer-assisted devices. Moreover, patients can also forward different test reports through Emails and store such documents for further use.
Rural population can seek maximum benefit through Telemedicine. Especially in developing countries where healthcare facilities are not available in rural areas, patients can contact doctors for treatment and diagnosis through Telemedicine.
Geographic Information System (GIS)
This system allows collecting the data regarding the geographical distribution of various diseases. In addition, it helps to analyze temporal and spatial trends, map the elements of risk and assess the healthcare requirements of a particular community. The analysts compile this data using computer software and analyze it to propose different solutions. The system helps to know the causes of disease and its preventive measures.
Computers and Bioengineering
Bioengineering is a collective study of medicine, engineering, and biology. It helps the researchers to improve human health via performing cross-disciplinary activities. It allows integrating engineering sciences with the medical sciences and using computers to diagnose diseases.
Bioengineering involves computerized analysis of blood samples and operation of Medical imaging systems. Analysis through bioengineering helps to provide cost-effective solutions to various healthcare issues.
Electronic Medical Records (EMR)
The conventional Paper-based medical record has its own weaknesses. Besides, it’s not possible to collect a large amount of data and reduce it to writing. This resulted in the development of Electronic Medical Records (EMR). It is a confidential and secure way of keeping medical records.
This system is another instance where computers are helping us to improve our healthcare programs. The use of information technology for health purposes has helped us to collect the data from various patients and store their clinical records.
Within the past few years, computerization of patient records has helped the researchers to deal with the common health issues in a systematic manner. EMR helps to track the patients with specific diseases like human immunodeficiency virus (HIV).
Health Management Information System (HMIS)
HMIS is an essential element of any healthcare program. It is a tool, which assists the doctors and scientists to gather, analyze, and use relevant information to improve the life of general masses. HMIS helps to collect data, and minimizes the responsibilities of field staff. It is a Web-based tool, which strengthens decentralization and helps to improve the planning ability.
