A computer repair technician is a person who repairs and maintains computers and servers.The technician's responsibilities may extend to include building or configuring new hardware,installing and updating software packages, and creating and maintaining computer networks. Computer repair technicians work in a variety of settings, encompassing both the public and private sectors. Because of the relatively brief existence of the profession, institutions offer certificate and degree programs designed to prepare new technicians, but computer repairs are frequently performed by experienced and certified technicians who have little formal training in the field

A repair technician might work in a corporate information technology department, a central service center, or a retail computer sales environment. A public sector technician might work in the military, national security or law enforcement communities, health or public safety field, or an educational institution. Despite the vast variety of work environments, all computer technicians perform similar physical and investigative processes,including technical support. Experienced technicians might specialize in fields such as data recovery, system administration, or information systems. Some technicians are self-employed or own a firm that provides services in a regional area. Some are subcontracted as freelancers or consultants. This type of technician ranges from hobbyists and enthusiasts that volunteer or make a little side money, to those who work professionally in the field. Computer malfunctions can range from a minor setting that is incorrect, to spyware, viruses, and as far as replacing hardware and an entire operating system. Some technicians provide on-site services usually at an hourly rate. Others can provide services off-site, where the client can drop off at the repair shop. Some have pickup and drop off services for convenience. Some technicians may also take back old equipment for recycling
While computer hardware configuration varies widely, a repair technician will work with five general categories of hardware; desktop computers, laptops, servers, computer clusters and smartphones / mobile computing. Technicians also work with and occasionally repair a range of peripherals, including input devices (like keyboards, mice, and scanners), output devices (like displays, printers, and speakers), and data storage devices such as internal and external hard drives and disk arrays. Technicians involved in system administration might also work with networking hardware, including routers, switches, fiber optics, and wireless networks. Computer Repair and Service
Software repair
When possible, repair technicians protect the computer user's data and settings, so that, after repair, the user will not have lost any data and can fully use the device with little interruption. Addressing the issue, the technician could take action as minor as adjusting one or several settings or preferences, but could also apply more involved techniques like installing, uninstalling, or reinstalling various software packages.A reliable, but somewhat more complicated procedure for addressing software issues is known as a restore (also referred to as imaging,and/or reimaging), in which the computer's original installation image (including operating system and original applications) is reapplied to a formatted hard drive. Anything unique, such as settings, or personal files will be destroyed if not backed up on external media, as this reverts everything back to its original unused state. The computer technician can only reimage if there is an image of the hard drive for that computer either in a separate partition or stored elsewhere.COMPUTER SERVICE|REPAIR|CENTRE|ALANDUR|THIRUVANMIYUR |KODAMBAKKAM|T.NAGAR|WES MAMBALAM|MMDA COLONY|MYLAPORE
On a Microsoft Windows system, if there is a restore point that was saved (normally saved on the hard drive of the computer) then the Windows Registry can be restored to that point, sometimes solving problems that have arisen after the time the restore point was created.
Computer cleaning
Computer cleaning is the practice of physically cleaning the interior, and exterior, of a computer including the removal of dust and debris from cooling fans, power supplies, and hardware components. This should be done after certain period of time (weekly/monthly). A computer being with such dust and debris may lead to improper working or running
Backup
Main article: Backup Important data stored on computers may be copied and archived securely so that, in the event of failure,the data and systems may be reconstructed. When major maintenance such as patching is performed, backup is recommended as the first step in case the update fails and reversion is required.
Disk cleanup may be performed as regular maintenance to remove these. Files may become fragmented and so slow the performance of the computer. Disk defragmentation may be performed to combine these fragments and so improve performance.
Computer maintenance activities are specifically exempt from the Digital Millennium Copyright Act and so copies of copyright files may be made in the course of maintenance provided that they are destroyed afterwards.
Registry Operating systems files such as the Windows registry may require maintenance. A utility such as a registry cleaner may be used for this.
A computer is a general purpose device that can be programmed to carry out a set of arithmetic or logical operations automatically. Since a sequence of operations can be readily changed, the computer can solve more than one kind of problem. Conventionally, a computer consists of at least one processing element, typically a central processing unit (CPU), and some form of memory. The processing element carries out arithmetic and logic operations, and a sequencing and control unit can change the order of operations in response to stored information. Peripheral devices allow information to be retrieved from an external source, and the result of operations saved and retrieved.
In World War II, mechanical analogue computers were used for specialised military applications. During this time the first electronic digital computers were developed. Originally they were the size of a large room, consuming as much power as several hundred modern personal computers (PCs). Modern computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space.[2] Simple computers are small enough to fit into mobile devices, and mobile computers can be powered by small batteries. Personal computers in their various forms are icons of the Information Age and are what most people think of as “computers. However, the embedded computers found in many devices from MP3 players to fighter aircraft and from toys to industrial robots are the most numerous.COMPUTER SERVICE | REPAIR | CENTRE | RAMAPURAM | SAIDAPET | ADYAR | THARAMANI | VELACHERY | MADIPAKKAM | CHROMPET | RAMAPURAM
Etymology The first use of the word “computer” was recorded in 1613 in a book called “The yong mans gleanings” by English writer Richard Braithwait I haue read the truest computer of Times, and the best Arithmetician that euer breathed, and he reduceth thy dayes into a short number. It referred to a person who carried out calculations, or computations, and the word continued with the same meaning until the middle of the 20th century. From the end of the 19th century the word began to take on its more familiar meaning, a machine that carries out computations.

Dust
Dust and other cruft may accumulate as a result of air cooling. If filters are used to prevent this then they will need regular service and changes. If the cooling system is not filtered then regular Computer cleaning may be required to prevent short circuits and overheating.

Computer maintenance activities are specifically exempt from the Digital Millennium Copyright Act and so copies of copyright files may be made in the course of maintenance provided that they are destroyed afterwards.

Service intervals
Depending on the environment, computers should be serviced at least once per quarter, though monthly service is optimal. Regular servicing helps computers run at their peak performance

History
Rudimentary calculating devices first appeared in antiquity and mechanical calculating aids were invented in the 17th century. The first recorded use of the word "computer" is also from the 17th century,applied to human computers, people who performed calculations, often as employment. The first computer devices were conceived of in the 19th century, and only emerged in their modern form in the 1940s.
