How To Select A Computer Technician?
Jan 21st
A computer technician is someone whose job is to maintain and repair computers and servers. A computer technician may be internal or external depending on the size of the organization. Usually large organizations, which have heavy-duty applications with a network of computers and servers, employ their own team of computer technicians.
A person with little knowledge of the intricacies of a computer cannot sort out errors and problems that crop up from time to time, depending on the usage, and this is when computer technicians come into play. There are several organizations, which have a pool of technicians to help you figure out the problem with your computer or even do maintenance for maximum efficiency of the computer. The job of a computer technician, as most people may think, is not an easy one. A person aspiring to become a technician has to go through a rigorous learning and test process.
An exam certified by engineers and professionals is conducted by the organization ExpertRating. This is a 40 minute exam and a person has to answer questions related to computer hardware concepts and repair, memory and storage devices, memory card, ports and expansion slots to name a few. So most qualified computer technicians are capable of handling any problem related to your computer.
There are also specializations in the field and this is necessary in case of core applications such as information systems, data recovery and systems administration when an organization is working over the globe and wants to process the data at once. But speaking in general the repair problems may range from incorrect settings to virus infection to replacing the hardware of a system. This is where the expertise of the computer technician is very handy.

The Ongoing Transformation Of Hardware
Jan 19th
Before the 1970s the word “hardware” usually meant one of two things: the beautiful chrome handles on your new dresser and the kitchen cabinets, or the hammer, saw, and nails that you purchased at the local hardware store. Then came the computer boom! Hardware took on a new meaning! If all the programming that made a computer work were called software, then the hard box and its components took on the name of hardware.
Hardware became a massive, competitive industry that expanded beyond the largest, most powerful dreams of the 1970s. Made of hundreds of various components that can be added, disconnected or exchanged depending on which features you want, the computer has a versatility that is limited only by ones imagination, budget and, realistically, one’s patience.
The basic components consist of the system unit itself (which contains the so-called brains of the computer, the CPU, plus various items referred to as ‘boards’), the keyboard, mouse, speakers, and of course, the monitor. To these basics one can add printers, scanners, PC cameras, digital cameras, video cameras, and joysticks.
During the mid 1980s several home-type computers became available for the courageous home-computer geek. These used only floppy disks, for the hard disk was still not portable in size. Writing a book could use up to 75 floppy disks and nevertheless was a major improvement over creating or working with a typewriter.
After a few years the amazingly huge 10 MB Hard Disk came out for home use, replacing the need for using floppies except for backups. Since 10 MB didn’t really hold all much data, the world of floppies was still lively.
