What A Computer CPU Is And Does
November 4, 2011 | 
Author The computer CPU (Central Processing Unit) is the part of the machine that makes the computer function, basically. It is responsible for carrying out the instructions of a program, which is done by accessing information from the memory and performing some specific action with it. After performing this action, it performs a ‘writeback’, wherein the changed information is re-written onto the memory.
Although they did not start out this way, modern CPUs are microprocessors. The invention of these microprocessors and their subsequent revisions is what has allowed modern machines to reach the ‘clock’ speeds that they do. These speeds are referred to as processor speeds, and have reached into the gigahertz range in recent years.
Many of these CPUs have reached their capacity for performing operations, which is why in recent years, manufacturers have turned to multiple core machines. The number of cores refers to the number of processors in the machine, and the more cores, the more tasks that can be performed simultaneously at peak speed. Theoretically, these machines should be faster than they really are. Software is generally considered the problem with reaching theoretical maximum speeds.
Computers create heat, something that anyone who has ever used a laptop on their lap can verify. Too much heat causes the machine to shut down in order to prevent damaging itself. There are several methods of keeping the area cool, including fans (air cooling) and liquid cooling. Air cooling is by far the more common of the two.
Allowing an air-cooled machine to build up dust, or not allowing proper clearance from objects can increase the temperature to a dangerous level. This can not only ‘fry’ the circuits and damage the machine beyond repair, but it can also cause fires in severe cases. This is why most computers come with detailed instructions on how to position them (such as not placing the machine directly on carpet or another soft surface).
Liquid submersion cooling is performed by materials such as oils, in which the CPU is submerged. It is rare because it is prone to problems– leakage being the main one. If the material leaks into the other components of the machine, damage occurs and destroys the computer. Evaporation means that the liquid must be replaced periodically, which also increases the chances of damage via spills.
Water cooling is not a submersion method. Because the properties of oil and water differ, they must be used in different manners to cool machines. It is much more efficient at removing heat than air cooling, and because of this, has been used for mainframe computers and jury-rigged by users for many years. It is still quite uncommon in commercial personal computers, but is present in a few. Potential complications such as condensation and leaking make it less popular than air cooling in all but the highest-performance machines.
Machines these days can do things that machines twenty years ago could only dream about, and CPUs are one of the major things that are responsible for that. Since the invention of the microprocessor, personal computers have gone from being calculators and word processors to being capable of multiple different complex actions at the same time. Supercomputers are even more powerful. If it weren’t for the invention of the microprocessor computer CPU, none of these things would be possible.

Printer Repair Preventive Maintenance
As a printer repair company in Toronto, we come across different printer issues and most of these issues are similar in nature. Some printers leave smudges on the pages, some create Creases or curls on the paper or paper jam while other misprints on papers. These are very common calls from the printer customers. These problems happen on all the printer models including Laserjets, Color laserjets, Multifunction printers, Designjet or plotters and even ink jet machines.
Today’s printers are very smart and versatile in their functionalities. Proper care and regular preventive maintenance can certainly enhance their productivity and life span saving you headaches of printer repairs. Although the manufacturer provides all the necessary information in the printer’s user manual, end users do not typically understand that it is their responsibility to know this information. Here are some of things you can do to enhance your machine’s life:
Always try to keep the machine free from dust and moisture. Dust is in fact the biggest enemy of printers as it causes paper jams and machine jam as it can easily penetrate the sensitive parts of the machine. You can either use a clean cloth or Air Duster to clean wipe the dust accumulated on the Laser printers. You can also vacuum clean the printers if you have the specialized tools to vacuum clean the machine. Be careful to use it only when the printer is unplugged and do not use it over complicated machine parts. Let a certified printer repair technician handle this job if there is some major problem. Try to inspect the paper pickup rollers for dust or cracks on regular basis as these are the major cause of printer paper jams. Also if you can, check for the separation pads located in the trays for dust or cracks. If it is dusty or, clean with alcohol or a water-dampened lint-free cloth or swab. Separation pads should be replaced together with pickup rollers.
Finally when using a reliable printer repair company, keep in mind the techs are experienced and most important they have the source to all possible parts. Some printer repair technicians are good in service but when it comes to parts, they have limited access which creates problem for the repair. A good printer repair tech should always do his proper homework before going in the field to fix a printer. He should always study the possible error issues so that he can start working right away on fixing the issue rather than doing the guess works by using hit and trial.
