In this article, we will explore the different types of computer hardware and their functions. What is Computer Hardware Computer hardware refers to the physical components of a computer system. It includes all the components that can be touched, seen, and used to interact with a computer, such as the monitor, keyboard, and mouse. Hardware is different from computer software, which refers to the programs and applications that run on a computer system. History of Computer Hardware The history of computer hardware dates back to the 1820s when Charles Babbage, an English mathematician, and inventor, designed the first analytical engine, which was considered to be the first mechanical computer. With time, more complex electronic computers were developed, including the first Intel microprocessor in 1971. Since then, computer hardware has continued to evolve, becoming

The Medicines and Healthcare products Regulatory Agency (MHRA) has appointed Dekra to certify medical devices in the UK. Dekra Certification UK has joined the three current UK approved bodies, increasing the UK's capacity to process conformity assessments for medical devices to ensure safe and effective devices reach the UK public. An approved body is an organisation that has been designated by the MHRA to assess whether manufacturers and their medical devices meet the requirements set out in  the UK Medical Devices Regulations 2002. Following an appropriate assessment, the new approved body will issue relevant certification allowing manufacturers to place a UKCA marking on their products before putting them on the market. Dr Laura Squire, chief healthcare quality and access officer at the MHRA, said: "This is a major milestone in our mission to ensure patients across the UK have access to the high-quality medical devices they need to protect their health.

Advanced technology is its flexibility. wheelchair provide some technologies can be used at home like power wheelchair,hearing aids,moped in the workplace, and in school, expanding the ability of the user to participate in various spheres of daily life. Augmentative and alternative communication technology is one such area of IT progress.where we use of hearing aids for communication and It includes inventions such as speech-generating devices, Teletypewriter devices, adaptive pointing devices to replace computer mouse devices, and many others. The following impairments are some of the disabilities that affect communications and technology access, as well as many other life activities: communication disorders: hearing impairments: visual impairments: mobility impairments: a learning disability or impairment in mental functioning. Each kind of disability requires a different kind of accommodation like dumb person use hearing aids and this may require analysis by a medical specialist and in medical,hospital we can see that disable person use health care product, an educational specialist or a job analysis when the impairment requires accommodation. Assistive technology is the creation of a new device that assists a person in completing a task that would otherwise be impossible,we take some example if some one not walk but now days they can do by use of power wheelchair,basic wheelchair,commode wheelchair. Some examples include new computer software programs, and inventions such as assistive listening devices, including hearing aids, and traffic lights with a standard color code that enables colorblind individuals to understand the correct signal,mode also useful for wondering in one way to another way. now we talk about adaptive technology so adaptive technology is the adaptation,modification, of existing devices, methods, or the creation of new uses for existing devices, to enable a person to complete a task. Examples include the use of remote control

Reacting to recommendations from a UK-first independent review, the Department of Health and Social Care (DHSC) has outlined action to tackle potential bias in the design and use of medical devices. Professor Dame Margaret Whitehead, professor of public health at the University of Liverpool, was appointed to lead the review, which focused on three areas - optical devices such as pulse oximeters, AI-enabled devices, and polygenic risk scores (PRS) in genomics. The DHSC commissioned the medical devices review after concerns were raised that pulse oximeters - widely used during the COVID-19 pandemic to monitor blood oxygen levels - were not as accurate for patients with darker skin tones. There were worries that this could cause delays in treatment if dangerously low oxygen levels in such patients were missed. However, no evidence was found from NHS studies indicating that this differing performance had an impact on patient care. Accepting the report's conclusions, the DHSC has committed to several actions, such as ensuring the safe use of pulse oximeter devices across a range of skin tones within the NHS and eliminating racial bias from data sets employed in clinical studies.

The Medicines and Healthcare products Regulatory Agency (MHRA) has advised the public to exercise caution when buying anti-choking devices online, ensuring these products are purchased from reputable sellers. As estimated by the regulator, more than 10,000 counterfeit or unbranded anti-choking devices have been purchased by the public within the last two years through listings on online marketplaces such as Amazon and eBay, as well as drop-shipping websites. People are cautioned that the use of such products poses a substantial risk of failure in clearing blockages and could exacerbate the situation by pushing obstructions further down into the airway passage. Dr Alison Cave, MHRA Chief Safety Officer, said: "Buying anti-choking devices that do not have a valid UKCA or CE mark increases the risk of receiving a product which does not include appropriate instructions and is either fake or does not meet the UK's regulatory requirements. "These products do not meet our strict quality standards and may put your health and safety at significant risk by failing to resolve or even worsening choking incidents."

Britain called on Sunday (November 21) for international action on the issue of medical devices such as oximeters that work better on people with lighter skin, saying the disparities may have cost lives of ethnic minority patients during the Covid-19 pandemic. Health secretary Sajid Javid said he had commissioned a review of the issue after learning that oximeters, which measure blood oxygen levels and are key to assessing Covid patients, give less accurate readings for patients with darker skin. "This is systemic across the world. This is about a racial bias in some medical instruments. It's unintentional but it exists and oximeters are a really good example of that," Javid said during an interview with the BBC. Asked whether people may have died of Covid-19 as a result of the flaw, Javid said: "I think possibly yes. I don't have the full facts." He said the reason for the discrepancies was that a lot of medical devices, drugs, procedures and textbooks were put together in white majority countries.
