What should I do if I have a computer?

Computers seem to have become a necessity at home, but do you know how to buy a home computer that really meets your needs? The following article will give you a thorough understanding of the application scope of home computers. Functional requirements and upgrade considerations We should know that all household appliances currently used at home probably have specific functions, such as air conditioning, refrigerator, TV, tape recorder and vacuum cleaner ... So what role should computers play in the family before they can be classified as so-called household appliances? In fact, you can explain which hardware devices are needed for each function from the following functions that are commonly used in your home. File processing, simple text input, simple arithmetic processing and basic chart drawing are the most basic functions of the computer. If your home computer really only needs such a simple function, and you don't have any upgrade plan for this computer, then I suggest you buy a so-called low-cost computer, because it is absolutely enough to meet your requirements. However, we should pay a little attention to input devices such as keyboard and mouse, and friends with learning disabilities can also consider using handwriting input. ● Connecting to the Internet Connecting to the Internet should be an essential basic function for all computers at present. At present, there are several ways for computers to surf the Internet, including 56K Modem, ISDN, Cable Modem and ADSL. Of course, it depends on the user's own needs, but if we consider the bandwidth demand and economic benefits of home computers for the Internet in the future, I suggest that ADSL and ISDN should be the mainstay. ● It is not a digital fax/answering machine. Don't think that after upgrading to ADSL, the 56K modem will be useless and can be given to friends and relatives. When a modem is connected to a computer and equipped with appropriate applications, it can become a super powerful fax machine and digital answering machine. Instead, traditional fax machines that are occasionally "funny" should be discarded. When there are so many TV programs on another TV, it seems that one TV can no longer meet the needs of everyone in the family. At this time, if the home computer is used as another TV to watch programs, then the home computer has one more function. In fact, it is quite simple to let the computer at home watch TV programs. As long as it is connected to the so-called "TV box" on the market at present, it can also be connected to the projector through the AV terminal provided by such products, which really kills two birds with one stone. In addition, if you want your home computer to have the function of capturing TV program images, you can configure an image acquisition card. In addition to the basic functions mentioned above, there are several advanced functions that home computers may play. ● Can the computer in the DVD player replace the DVD player? The answer is absolutely yes, but the cost of achieving the ideal image effect may even exceed that of buying a DVD player. What I want to say is that at present, a computer with basic configuration, plus a graphics card with MPEG2-2 decompression capability and a DVD read-only drive, can play DVD movies. Of course, if you don't want to watch DVD movies on a computer screen that is only 15~ 19 inches, then a video card with TV OUT function is essential. With it, you can enjoy DVD movies comfortably on the TV screen. What makes computers spend a lot of money is the AC-3 sound effect that reflects DVD movies. At present, generally cheap PCI sound cards have no audio decoding output of AC-3, and only provide SPDIF interface at most. If the computer is equipped with AC-3 sound decoding function, only high-quality speakers with 5. 1 channel can show the real effect of home theater, which is a considerable expense. Just now, when the video recorder mentioned that the home computer can be used to watch TV programs and take pictures, it can also be made into a general video recorder. To achieve this function, computer hardware must first have the function of capturing TV images. This can be achieved in several ways. One is to directly use an image acquisition card with a TV tuner, and the other is to obtain TV images through a TV box, and then connect the acquisition card to collect images. Both methods have advantages and disadvantages, and friends can measure them according to their own needs. I also want to explain to you that there are some applications that can make computers have the function of pre-recording programs, which invisibly increases the powerful function of computers to capture TV images. ● The home digital imaging center is right! It is a home digital imaging center, which makes the status of home computers in by going up one flight of stairs. But then again, although it is feasible to make a home computer into a home digital imaging center, the cost will be high. You can choose to use a flat scanner or a digital camera as an image input device. My suggestion is that at present, a scanner with 600bpi platform is not expensive. It can be used not only to input photos, but also to scan words, so it is quite suitable as an image input device for home computers. As for the digital camera, although it is quite convenient to carry and use, it is still a high-priced product at present. Friends who want to buy this kind of equipment should carefully consider whether it is cost-effective. In addition, in order to print the photos processed in the computer beautifully, a color inkjet printer and special inkjet photographic paper that can produce photo effects are essential. At present, the increasingly popular photo printer is also a good choice. In addition to static images, dynamic images have been paid more and more attention. Now many friends want to transcribe their long-cherished movies into VCD. In fact, it only takes a few simple steps to make your own VCD film, which can not only be preserved for a long time, but also make a personal style film. And DV (digital video) has gradually become a hot topic recently. As long as the computer has the IEEE 1394 specification, it can use DV for all-digital movie editing, without any risk of image quality distortion, and it can achieve a perfect state of all-digital. ● Home monitoring system Hey hey! Since the computer at home is idle, let it also have the function of monitoring. Being a smart "electronic watchdog" can not only protect the safety of the home, but also scare off those ungrateful thieves. Why not do it overnight? Of course, if you want a home computer to have such a function, besides the cooperation of application software, the camera is also a key hardware device. ● Home appliance control center The so-called home appliance control center means that all electrical products in the home will be under the management of the home computer. For example, in the future, you can control the gas stove, refrigerator, air conditioner, TV, tape recorder, microwave oven, water heater, rice cooker and even light switch at home through computer. Of course, this requires close cooperation between home appliance manufacturers, but if this effect can be achieved, I believe it will be a major change in human life. The perfect home computer in the future. What I told you above is a home computer close to reality. In fact, everyone has different functional requirements for the home computer, so everyone has different platforms for the perfect home computer. I just hope that after reading this article, everyone can know more clearly how to plan their perfect home computer. ..
