HOW TO BE A RELIABLE COMPUTER TECHNICIAN

LEARNING TO BE A GOOD COMPUTER TECHNICIAN AND TRUE

                 CHOOSING THE MAIN COMPONENTS
  1. CASING (AGENCY)

Casing is an important component to support the performance of a computer. The sections are:

a. Power Supply (power supplier). In this section we have to be extra careful. For, if the power supply to the inside of the casing is not good and if it is not very convincing at first glance, should not have been. Select the amount of voltage that can be supplied by the casing, for example 250 watts, 280 watts, 300 watts, or more as needed.

b. Bay and Port for Add-on Card. Notice how many bays alias column attached. Whether it's for a CD-ROM drive, DVD-ROM drive, and floppy enough drive.Selain bay, port for add-on card that is behind casing must also be considered.

c. Ventilation systems. Note the vent hole. Its nice that it has a sufficient air gap, well behind, above, disamping.2

. processor

The processor is a component of the fastest growing PC. Problems arise because the processor then confused, which processor is deemed most appropriate to the needs and the times.

a. Intel Celeron

In terms of technology, the processor is not particularly new. Front Side Bus is used for example is an ad that kept the speed of 66MHz (early version). Although it has a relatively small caches, Celeron Intel Celeron still trying to "move" forward in terms of technology. In this dprosesor, intel was issued tioe taking the match FSB 100 MHz Pentium 3.
Sekarag about speed, speed Intel provides several options, ranging from 533MHz to 1.3 GHz. Of particular interest are cheaper than Pentium 2.
b. AMD Duron

Processor fib alias AMD Advanced Micro Devices has pin number 462 is arguably as much "play" for the same class with the Celeron. Lots of options for speed, ranging from Duron Duron 800MHz to 1200MHz. From the technology side, Duron 1200MHz version of its carrying amount 64kb L2 cache does not display the new technology. The processor technology used was 0.18 micron.
Performance itself is quite good, especially for standard applications. Supported with affordable price, this processor was chosen among entry level and game center. Create the home processor was chosen, its easy overclocking process.
c. Pentium 3

If you want a processor with affordable prices but has enough ability, Pentium 3 is still be glimpsed. In this processor, must be smart (carefully) in choosing. The first type is the EB which means that the processor has 265KB of L2 cache on-chip with a 133MHz bus. Type yanglain is Pentium 3 type E which means has a 256KB L2 cache on-chip bus Taoi has only 100MHz.
Pentium3 also has 3 versions based on the process technology, which is common now using 0.18 micron, while the new type diseut Tualatin using 0.13-micron process technology. For commercially available speed of a Pentium 3 733MHz to 1.2 GHz.
d. Pentium 4

Intel Pentium4 inilahyang entrusted create hegemony pentium3 replace the mainstream.
Willamete version that uses 0.18 micron process technology with 256KB L2 cache by Intel is divided into two based on the existing pin on the processor. For the initial release version of the Pentium4 processor, it uses 423 pin to "erhubungan" with the motherboard and other devices. Meanwhile, the latest Willamate been carrying pin 478. The processor uses 478 pin is already using 0.13 micron technology that has several advantages such as lower heat, can be carried L2 512KB more.
Willamate version with speeds ranging from 1.3 GHz to 2 GHz. Meanwhile, the new version provides a Northwood and speed options are 2GHz and 2.2 GHz. Because there are two versions of this, it is recommended that when buying, should know exactly which type to use.
e. AMD Athlon

At least two types of AMD Athlon processors on the market, Thunderbird and Palomino AthlonXP aka eXtreme Performance. If there is an early version that carries a 100MHz FSB and 133MHz, AthlonXP have to support 133MHz FSB sebebsar. For now, the Thunderbird on the market still wearing 900MHz speeds up to 1.4 MHz. Meanwhile, ranging from speed AthlonXP 1500 + to 2000 +.
The main advantage of this AMD processor is fabricated its satisfactory for the overlocker. Moreover, the price is relatively affordable, these processors are now the norm among home and small and medium corporates.
Now living depends on you, would select which type of processor. A definite choice of processors will greatly influence the choice of devices such as motherbord and heatsink fan.
3. motherboard

Which motherboard should I choose to assemble the PC really topnotch, the answer varies. Choosing a liking moteherboard is easy-easy job already. Now we are looking for a step yag's easy and we remove the already.
a. When will use pentium3 or Celeron, then choose a motherboard that has as many as 370 pin processor socket aka socket 370. Meanwhile, Athlon and Duron processors if you want to use, use a motherboard with socket A or socket 462. Another case when choosing pentium4, when using 0.18 micron architecture, then choose a motherboard Socket 423 pin PGA. As for the Pentium4 0.13 micron architecture, select mini BGA 478 pin socket.
b. For an Intel Pentium 3 or Celeron, choose a motherboard with Intel 815E chipset or 815EP, VIA Apollo Pro series, Ali Aladdin Pro series, and SiS 63x series. For AMD Athlon or Duron then the choice will fall on the motherboard with a VIA chipset series KT, Ali Magik 1, and Sis 73x. It would be nice if, before determining which chipset will be used, compare the performance of one shipset with another chipset.
c. Make sure the motherboard to be selected has support for Ultra ATA/100 hard drive interface and has support for the AGP port (Acceierated Graphic Port). We recommend that you choose a motherboard that supports SDRAM and DDRRAM.
d. Choose a motherboard that has features additional ports adequate. To install memory DIMMs place, other than DIMM sockets, PCI bus number owned motherboard should also be considered. Motherboard is selected should have an AGP port.
e. Look for a motherboard that provides support functions - integrated functions: graphics cards, sound cards, LAN, modem, and more. And also look for a motherboard that offers overclocking via BIOS.
4. memory

                                                 SDRAM                                                       DDRRAM

 

Quality of memory is usually seen from the highest operating frequency can be achieved by the memory, the SDRAM, it can be seen jelasm on chips located on the memory. In the body can be seen the numbers preceded by a minus sign (-), eg -7.5: -6, and so on. This sign is used as a guideline in determining the maximum frekuensikinerja memory. The general formula is f - 1000 / T, where f is the operating frequency (MHz), and R is the period of memory, the numbers written on the memory chip. Quality of physical memory can be seen from the brand of chips used.

5. Hard Drive

Identify the needs and specifications of smart-pandailah understand hard before choosing.

Consider choosing hard drive speed 7,200 rpm (revolution oer minute) or higher; faster Nikai rpm faster then semakain ability, should speed reading gap of 12 milisecont (ms), and transfer at least 15MB per second.

6. IDE cable

This cable is used to mengoneksikan motherboard with hard drives, optical drives, and floppy drives. Latest models bebentuk round, so more probe and not easy broken.

EQUIPMENT REQUIRED
The main equipment needed if you want to assemble a PC of course screwdriver. We recommend using 1 complete screwdriver set. But if not possible a screwdriver positive (+) good quality is relatively adequate. Try screwdriver contains a magnet on the end so it is easy to install small screws.
Other equipment that is needed is an implanted metal bracelet (grounded). This bracelet will be used hand to eliminate static electricity that is in hand.
