A computer system is made up of different components typically engineered and manufactured by different companies and sold with a common badge.
To engineer compatible components manufacturers abide by standards. Knowledge of these standards allows computer systems technicians to remove and replace faulty components when there is a hardware failure.
Individual circuits are not repaired. Rather, the whole component is removed and replaced. Troubleshooting these factors generally involves reasoning and quite often a little help from the remaining hardware utilizing audible PC speaker beep codes known as BIOS beep codes.
The major aspects of a pc include;
The case and energy. Also referred to as the ‘box’, ‘tower’ or ‘chassis’, it does not take enclosure that houses each of the computer components. The power source coupled to the case is in charge of converting the (AC) current from a wall outlet into (DC) current utilized by your computer components.
The power could be included with the case when purchased being a component. Check that the ability output capacity is adequate for the hardware. Generally speaking, additional hardware including extra disk drives in addition to high-powered video cards may necessitate higher power output capacity from the power supply.
The motherboard. This will be the underlying circuit board that connects all the computer components. If your computer was a house then this motherboard is the concrete slab. All your computer components will connect with the motherboard some way and it will transfer data between components as required.
The Processor. This will be the brain. The processor power is measured in Giga-Hertz. Giga is often a standard multiplier for 1 billion just like kilo could be the standard multiplier for 1 thousand. And Hertz is a unit of frequency. The higher the frequency the faster the processor.
Today processors are sold as the dual and quad-core. Each core might be often considered as an individual processor package bundled into the one physical unit. The processor is usually unjustly blamed for slow systems. Other components like insufficient memory or inadequate video cards will often be the reason for poor performance.
Memory. A memory may be the hardware ingredient that is employed to temporarily store files and code for very intense access with the processor. It is more accurately called RAM (Random Access Memory) to counteract confusion with storage capacity inside the hard disks which can also be called ‘memory’. Current memory standards include DDR2 and DDR3. The motherboard memory slots decide which standard is correct to your computer.
Insufficient memory (RAM) is often a major reason for poor computer performance. One indicator that your computer might have insufficient RAM is that your Hard Drive light for the front panel of one’s computer case is on for prolonged periods when you find yourself not performing large storage tasks for example saving or opening big files.
A Video Card. The video card is in charge of generating output images for the monitor. Modern video cards include specialized hardware to boost 3D graphics performance usually related to game titles or computer-aided design software.
The current video card to the motherboard connection standard is PCI-E. When purchasing a relevant video card, the motherboard video card slot ought to be checked to ensure compatibility.
Mass Storage. The hard drive is a long-lasting persistent storage device that retains stored information even though it is powered down. This is a form of persistent storage is named non-volatile memory. The main system and applications are stored around the hard drive.
Hard disk capacity is measured in Giga-Bytes and the connection standard with all the motherboard will come in two flavors – IDE or SATA. A motherboard can typically support only a few hard disk drives with one being set as the ‘primary’ or ‘master’ drive which is used at boot time for you to load the main system.
The Monitor. The monitor accounts for the visual display. Screen size and refresh rates are factors that affect the costs of monitors. High refresh rates are often related to games.
