Computer Buying Tips

A desktop computer is divided into 2, that is assembled and built up. Computer assembly means we choose the parts or components that we want and then we assemble into a single unit that has a full computer functionality. Computers built-up means that we buy so a computer that has been assembled by the vendor or a particular company. So buy a computer built up exactly like buying a TV.

Then, why do we have to buy a computer assembly? Well Yes and No. Assembled computers have more value in flexibility. Depending on thickness desired features our pockets. The thicker, the broader our choice.

Computers built up is more simple at the time of purchase, but the price of PCs built up expensive. With the same specifications, PC assembly can be cheaper 40% - 50% rather than the PC built up. Excess PC built up the most significant is a longer life and is usually supplied genuine Windows software.

Parts check list when buying a PC:

Processor: The most common choice today is the AMD and Intel. AMD offers exceptional performance, especially for graphics, while Intel reliable for all needs. More processor options to the tastes and needs. If you like to play games and design, especially the 3d; AMD steady. If for the office, everyday use, to a server, or internet cafe, Intel just that easy.

Motherboard, this makes him the most confused. Assorted brand as well as its features. What is clear what the seller asked the same motherboard compatible with the processor of our choice as above. Brand my choice is Abit, ASUS, MSI, Foxconn, Intel. Brands that have proved reliable, at least in my experience.

VGA card: VGA card determines the quality of picture and usually for 3D rendering. There are two ports for VGA, PCI-Express (PCI-X) and AGP. PCI-X is the latest technology and offer 2 times the speed of AGP. Usually PCI-X is widely available in the latest motherboards. But if only used for office work, AGP was more than enough. And if you are funded limited, additional VGA card can be ignored if your motherboard has a built in VGA card.

Memory: Memory or RAM is temporary storage of high-speed. Currently available in the market is kind of DDR-1, DDR-2. Check if your motherboard supports it. DDR-2 clearly faster than DDR-2 at a price not much different.

Harddisk: If your motherboard supports SATA ragu2 do not use SATA. Old IDE port is less ergonomic and less quickly than SATA. The price is also not much different. To size it up to you. The bigger the more expensive of course.

Soundcard; Most mobo now equipped with a soundcard built this. So chances are you do not have to buy it. Unless you are a professional in the field of music. You can buy a soundcard add on a much more reliable as Soundblaster Audigy.

Power Supply: PSU (power supply unit) range, from cheap to super expensive. The more expensive of course, the more stable supply of electricity and the more durable components of your PC. But cheap does not mean that it is cheap. At least your computer can be used as usual. Usually the standard PSU is shared with the casing
The rest are accessories such as CD-ROM/DVD-ROM, CDRW / Combo / DVD-RW, Speakers, Monitors, Casing, UPS, Camera, Mouse, Keyboard, Printer, and so it's up to your taste. Whatever the brand, will not affect the performance or speed of the PC you have purchased. Be careful, expensive brand is not necessarily appropriate, purchase as needed.

Last is the software. Computer assembly is not accompanied by the original operating system software, so you have to buy it.
If it was interested in buying computer assembly, check out the nearest computer center. Here where the computer hobbyist looking for cheap computer assembly and of many kinds.

How to Select (Purchase) Computers are good

How to buy a computer.
First set your computer uses it for what?

Many people are caught up in how to choose a computer, usually people think if the faster the computer the better, what's always been so? The answer is no.

CHOOSE YOUR COMPUTER IN ACCORDANCE WITH usefulness

Okay, for example.
If you want to buy a computer for typing, dengarin songs, wrote the film dengarin what type of computer would you buy?

If only for that alone I recommend

TYPE typing COMPUTER AND MULTIMEDIA DENGARIN

Processor: 500 MHz

Memory: 256 MB

Harddisk: 20 GB

DVD-ROM

Monitor: 15 " flat


Is this enough? Hmmm this is far from enough.

Why? To know what is enough or we need to know basically ga first.

Understanding Computer Hardware

Understanding of hardware or in the Indonesian language is also called the name of the hardware is one component of a computer that is the nature of his instrument can be seen and touched by humans in the form of direct or real, which serves to support the process of computerization.

Hardware can work on orders that have been determined there is to it, or also referred to by the term instruction sets. With the commands that can be understood by the hardware, the hardware can perform a variety of activities that have been specified by the command.

Physically, the computer consists of several components, which is a system. The system is the components work together to form a union. If one component does not work, will result in the malfunction of a computer properly. Computer components are included in the category of hardware elements (hardware). Based on its function, the computer hardware is divided into:

1. divice input (input units)

2. Process devices (processing units)

3. Output devices (unit output)

4. Backing Storage (storage unit)

5. Peripherals (additional unit)

basic components of a computer that consists of input, process, output and storage. Input device consists of a keyboard and mouse, Process devices are microprocessor (ALU, Internal Communication, Registers and Control section), Output devices consist of a monitor and printer, external memory storage consists of hard disk, floppy drive, CD ROM, magnetic tape. Internal storage memory comprises RAM and ROM. While Peripheral Device component is an additional component or as a component that does not exist or not exist previously. Peripheral Component's an example: TV Tuner Card, Modem, Capture Card.

1. Input Unit (Input Device)

This unit serves as a medium for entering data from the outside in a memory and processor to be processed to produce the required information. Input devices or input units are commonly used personal computers (PCs) is a keyboard and mouse, keyboard and mouse is a unit that connects the user (users) with a computer. In addition there is the joystick, which is used for playing games or games with the computer. Then the scanner, to take pictures as digital images that can later be manipulated. Touch panel, using a finger touch user can perform a file access process. Microphone, to record the sound into the computer.

Serves as a media input device to input data from external systems into a memory and processor to be processed and produce the necessary information. Data entered into the computer system to form an input signal and maintenance inputs. Signal input form data entered into the computer system, while maintenance input shaped the program used to process the data entered. So in addition to input devices used to input data can also be used to enter the program. Based on its nature, the input devices can be classified into two namely:

• peratalan direct input, the input is entered directly processed by the processing equipment. For example: keyboard, mouse, touch screen, light pen, digitizer graphics tablet, scanner.

• Equipment indirect input, input via a particular medium before an input is processed by the processing equipment. Examples: punched cards, floppy disks, hard disk.

Units input or the input device is composed of several kinds of devices are:

a. Keyboard

The keyboard is the most important input unit in a data processing by computer. The keyboard can function enter letters, numbers, special characters and as a medium for the user (users) to perform other commands are needed, such as saving files and opening files. Creation of a computer keyboard comes from the typewriter model created and patented by Christopher Latham in 1868, and in 1887 the company produced and marketed by Remington. Digunakanan current keyboard is a QWERTY type, in 1973, the keyboard is inaugurated as the standard keyboard ISO (International Standards Organization). Number of keys on the keyboard this time amounted to 104 keys. Keyboard now that we know has some kind of port, ie serial port, ps2, usb and wireless.

Keyboard Types:

1.) QWERTY

2.) Dvorak

3.) KLOCKENBERG

The keyboard is usually used is a QWERTY style keyboard, which is shaped like keys on a typewriter. QWERTY keyboard has four parts:

1. typewriter key

2. numeric key

3. function key

4. special function keys.

b. Mouse

Mouse is one unit of input (input device). The function of this tool is to move the pointer or cursor quickly. Also, it can as a practical command and faster than with a keyboard. Mouse began to use the most since the operating system has been based GUI (Graphical User Interface). electrical signals as a mouse input device is generated by a small ball inside the mouse, in accordance with the shifts or movement. Most of the mouse consists of three buttons, typically only two buttons are used, namely the left and right buttons. When this mouse is also equipped with rollers button (scroll), where the location of this button located in the middle. The term suppression is called by clicking the left button (Click) where the emphasis is going to function when the mouse is at a designated object, but if not in a designated object of this emphasis will be ignored. In addition there is also another term called the move (drag) that is pressing the left mouse button without releasing it with while being moved. This drag will cause the object will be moved or copied to another object and other possibilities. The emphasis of the left mouse button twice quickly and regularly called on double click (double click) while pressing the right mouse button once called the right-click (right click) Mouse consists of several ports of serial mouse, mouse ps / 2, usb and wireless

care kompuer

1. Defrag your hard drive regularly. Defrag function is to organize and sort your files by type of hard drive files / data in such a way that will facilitate the read / write so that the workload will be lighter which could ultimately extend the life of the hard disk. How to click the Start menu> Programs> Accessories> System Tools> Disk DefragmenterSaat perform this function there can be no other programs running including screen because it would disrupt the function of this defrag.
2. Activate the screensaver is aesthetic addition, the screensaver has another function which is important. CRT televisions also use a phosphor to display images. If the monitor displays the same image for a while then there is the phosphorus that burns continuously. This can lead to problematic monitor the picture becomes dim / less clear. Another case if your monitor is LCD, the LED which is equipped with energy saving, the screensaver is not too needed lagi.Cara + enabled screensaver can be done in many ways, one click Start> Control Panel> Display> click the screensaver tab, then select according to taste you.
3. Place adequate ventilation monitor and the CPU in such a way that the ventilation air to and from the monitor / CPU quite smoothly. Who lack good ventilation will cause excessive heat so that the components / electronic circuit in it will be a fast heat so it can shorten component life tsb. Therefore, try to distance between the monitor / CPU with wall / wall of at least 30 cm. If I need to install a fan in the room.
4. Wear stavolt.Pakailah UPS or UPS for power in anticipation of a sudden death which can result in damage to the hard drive. If I have no UPS, use Stavolt to anticipate the ups and downs of electric voltage.
5. Close / close programs that do not use every program which is loaded or run requires memory (RAM) so that more courses which run who consumed more memory. This is in addition can cause the computer to run slow (slow) is also becoming heavier workload which can ultimately shorten the life of the component / computer.
6. Install anti-virus program and update regularly To be able to recognize new virus/trojan2 should update your antivirus program regularly. Virus already spreading in the computer can make you re-install the computer. This is in addition to costs will also cause your hard drive will be more easily damaged than if it is not often re-installed.
7. Clean the Recycle Bin in rutinSebenarnya files / folders that we deleted from the hard drive does not disappear because it will be accommodated first in the Recycle Bin is the intention for a moment if you still need to return again. Recycle Bin which will also have a lot of disk space-consuming which can cause the reading of the hard drive so lelet.Caranya run the Windows Explorer> click on the Recycle Bin> click File> click Empty Recyle BinAtau You can run Disk Cleanup function Way Click Start> Programs> Accessories> System Tools > Disk Cleanup> and then select the drive which will be cleaned> after that Tick the Recycle Bin option if you need to also check the other (such as temporary files, temporary internet files), after click OK.
8. Do not put Speacker Active monitorKarena too close to the existing magnetic field at speacker will affect the color of the monitor into the monitor that is uneven or mottled.
9. Uninstall or remove programs that do not bergunaRuang hard drive which consumed too much will slow down the read / write drive so that the workload will be more severe so that the disk will be easily damaged.
10. Clean the motherboard and other peripherals from the dust in berkalaSetidaknya six months this should be done. Open the casing first and then clean the motherboard and other peripherals (RAM, Video Card, Modem, Sound Card, CDR / CDRW / DVRW, TV tuner) with a soft brush. At the time the computer is not used close the computer (monitor, CPU, keyboard / mouse) with a cover so that dust does not easily fit into a computer.
11. Connect the ground wires. If the casing nyetrum, take a cable with a length as needed, the tip of an entity associated with the CPU (the casing) while the other end planted in the soil. This will be to neutralize the electric currents which "stray" so it can make more durable electronic components. (Taken from various sources)

how to maintain computer ..?

Computer Maintenance Tips Yeng There are a few tips to consider in connection with the use of computers to be more secure and durable of them are:
1. Provide UPS, often times the voltage up and down or even die suddenly will have less good on the PC, especially PC that had long, will cause damage to the Power Supply, damaged hard drive, even Morherboard.
Especially hard drive, hard drive needs to stability while working, when a sudden power failure occurs surprises that could cause tergoresnya track tecordingnya then timbulah bad sector, bad sectors can only be seen if we check through scandisk. bad sector can not be in the content files for the operating system or storing data, thereby reducing the capacity of the hard disk itself. Therefore, in order to try the UPS or the external battery is provided as a safety net in case the lights off the computer to stay alive for some time, so that there is a chance to shut down the computer according to the procedure.
2. Stavolt, for UPS which includes stavolt (stabilizer up and down the voltage) is not problematic, but that does not include stavolt in it then it is better provided additional stavolt as a stabilizer, so that although the voltage up and down too, does not interfere with its own computer security. 3. Clean from dust, usually CPU tower in place at the table next to the user, the put on the floor so that the possibility of entry of dust into huge CPU, Dust as of heat, so what if the CPU components such as processors, though hidden dust can enter, too, memory / RAM often subject to dust, and work computer so the crash, hang or even a computer can not arise beep sound is turned on .... then check and immediately clean it is kompenen, plug back in and turn. 4. Avoid taxable Water, did not rule out keyboard soaked drinking water. Ever incident my keyboard accidentally hit the water, finally came to pass konseleting on lempegan on the keyboard, though had been cleaned and dried in the sun though can not be repaired, so need to replace new. 5. Voltage, the voltage used in Indonesia for 220 volts, but for computer Japanese products are still 110 volts, so that when the computer turned on Japanese products, do not forget to provide an adapter to reduce the voltage from 220 volts ke110. if not well .... fire for sure! ... 6. Lightning shock, to lightning-prone areas, especially computer networks that connect the tower is not equipped with lightning rods, dangerous when hit by lightning will spread throughout the network. therefore provide better lightning rod. 7. Keep away from magnetic fields, magnetic fields can interfere with the performance of the CPU also monitors. 8. For the sake of data security and computer systems, existing Pasrikan Antivirus and always updated. 9. Make sure there is an additional utility program to remove the remaining registry and junk from the Internet (cokies)

MAINTAIN COMPUTER TIPS

Perhaps now, the computer becomes an item that must be known and known mainly by most students. It is not mandatory, but of course we know the computer will make what we do easier. Even more than that, a collection of computers that are connected in a network or networks can be used to share resources and information.
The question that frequently appear are, how if I can do tto take care of the computer ..? because no computer that we have rarely had damaged either due to a virus, a component in the computer CPU or crash damaged his installation that we do on the computer.
It is better if we know how to treat the computer so that before the computer was broken, we are hard-very hard to take care of our computer, but if his time had been damaged yam au how again, here are the author wanted to share some tips for caring for your computer .... so lets check it now

1. Clean the motherboard and other peripherals (hardware) of dust on a regular basis. To clean it use a brush to smooth Kiga small and medium size. At least once every two months this should be done. Open the casing first and then clean the motherboard and other peripherals (RAM, Video Card, Modem, Sound Card, CDR / CDRW / DVRW, TV tuner) with a soft brush. At the time the computer is not used close the computer (monitor, CPU, keyboard / mouse) with a cover so that dust does not easily fit into a computer.
2. Uninstall or remove programs that are not useful. Disk space consumed too much will slow down the read / write drive so that the workload will be more severe so that the disk will be easily damaged. Usually will appear warning also our disk space is full. Windows operating system already supports things like this will
3. Clean the Recycle Bin on a regular basis. Actually the files / folders that we deleted from the hard drive does not disappear because it will be accommodated first in the Recycle Bin, but there are several types of settings that we can use, among others, provide a warning when deleting, remove and then store it temporarily or permanently removed. For settings that remove and then stored in these shelters with the intention for a moment if you still need to return again. Recycle Bin that has a lot of hard drive will also take up space that could lead to reading the hard drive so slow. How to run Windows Explorer>> click the Recycle Bin>> click File>> click Empty Recyle Bin. Or you can run the Disk Cleanup function Way Click Start>> Programs>> Accessories>> System Tools> Disk Cleanup>> then select the drive which will be cleaned>> after that Tick the Recycle Bin option if you need to also check the other (such as temporary files , temporary internet files), after click OK.
4. Install anti-virus program and update regularly. To be able to recognize new virus/trojan2 should update your antivirus program regularly. The virus is already spreading on the computer can make you re-install the computer. This is in addition to costs will also cause your hard drive will be more easily damaged than if it is not often re-installed. It's good that we menonaktifakan system restore by right clicking My Computer>> select System Restore>> and then check the check box by keretangan Turn off System Restore on all drives
5. Close / close programs that do not use every program which is loaded or run requires memory (RAM) so that more courses which run who consumed more memory. This is in addition can cause the computer to run slow (slow) is also becoming heavier workload which can ultimately shorten the life of the component / computer
6. Wear stavolt.Pakailah UPS or UPS for power in anticipation of a sudden death which can result in damage to the hard drive. If I have no UPS, use Stavolt to anticipate the ups and downs of electric voltage.

Think Twice Before You Toss Your Old Electronics in the Trash Can

hink twice before you toss your old electronics in the trash can. You may not know it but consumer electronics are full of dangerous heavy metals that don't need to wind up in landfills. In landfills these heavy metals will leach into the soil and eventually make it into our water supply. From there it will get into our drinking water and cause health problems. This is a growing concern as the pace of technological innovation continues to increase. People are getting rid of their electronics faster now than ever before as technological advancements make better electronics available faster. At the moment it is estimated that 70% of all dangerous heavy metals in landfills come from consumer electronics even though they only make up 2-3% of our total trash and these numbers are projected to continue rising.

Heavy Metals aren't the only environmental problem caused by the massive amounts of consumer electronics piling up in landfills. Most consumer electronics also contain a lot of plastic and due to the high temperatures these plastic casing can be exposed to they generally have a flame retardant additive in them. This is a chemical that is mixed into the plastic resin during production that increases the melting and burning point of the plastic. The nature of this additive makes it leach out easily in hot weather like we experience here in Texas and across the south. This chemical then leaches into the soil and eventually it too makes it into our water supply.

The problem also expands beyond our local landfills in the US. The same heavy metals that make consumer electronics harmful in landfills make them valuable to countries that need raw materials such as China and India. The problem however, is that when electronic waste is shipped to these areas it is shipped in bulk. Not all of the electronics shipped can actually be recycled at the plants they are sent to overseas. This leads to toxic electronic waste dumps building up in rural areas of countries like China and India near these facilities. Furthermore, these countries don't have the environmental regulations or inspections in place to do anything about these toxic dumps of electronics and they pose a serious threat to the local communities in these regions.

In Texas the problem has gotten serious enough to prompt a response from the state government. The Texas legislature in Austin recently passed a measure that requires computer manufactures selling products in Texas to provide free recycling for old and broken computers. This will help decrease the amount of electronic waste in Texas' landfills but is by no means an adequate solution to the problem. The law does nothing to address the growing problem of TVs in landfills sense it doesn't require TV manufactures to provide free recycling of TV's. It is anticipated that with the recent switch to digital TV there will be a large number of old, non-digital compatible TVs, being disposed of. In the absence of easy recycling, a lot of these TVs will end up in landfills where they will pollute the soil and ground water. Further governmental action is needed to prevent this problem from getting worse.

So next time you have electronics to get rid of, be it a laptop or a cell phone, think twice before dropping it in the garbage can. Instead take them all to your local Goodwill where they will be tested and re-sold, repaired, or recycled depending on their condition. This is a great way to help out the community and keep nasty chemicals out of our water supply. In Austin you can also drop off electronics at an Ecology Action recycling center in Downtown or the cities landfill recycling diversion center in south Austin for no charge. Most cities provide facilities like this to help limit the amount of electronic waste that goes into landfills, so make the extra effort to find out where the nearest recycling drop off location is and take your old electronics there instead of sending them to the landfill.
