Technologies should and should not be invested in 2005

One year has come to a close and another one year Pcmag magazine's veteran journalists write about some technologies (CN) that deserve investment as well as technologies that we should not pour into a wasteful way.

Wireless Technology

Do not buy 802.11b: Investing in 'yesterday' wireless connectivity standards can save you investment costs, but this connection standard is hard to meet wireless entertainment requirements. altitude will come in 2006.

Can buy 802.11g: 'G' is a marketing symbol that tells us the 802.11g wireless connection standard is faster than 802.11b standard. The 'dual-g' standard can meet the video connection requirements around your home but this connection is gradually being replaced by the 'n' standard.

Should buy 802.11 pre-n: Why should we buy the 'pre-n' standard, let's consider what happened with 802.11g. Firstly, the network will still ensure safety when using the standard 'pre'. Many users have purchased the 'pre-g' (or 54G) standard before the 802.11g standard is approved and then all devices work well on this standard or just need to upgrade it. control. Maybe this is also the reason we recommend buying 'pre-n' standard.

Screen

Do not buy CRTs monitors: CRT monitors have the disadvantage of being bulky and occupying a lot of space. The advantage of this type of screen is cheap, but if you buy products online then the cost of shipping this type of screen will cause you to give up the idea of ​​buying this type of monitor.

Can buy large CRT models that incorporate high-definition TVs HDTVs: All the best technologies can be found anywhere but if you still want a big screen with high definition and under $ 1,000 then this type of screen is the last choice.

Buy LCD TVs or plasma screens: The advantage of this type of screen is that it is thin and gorgeous while the cost of these monitors is going down quite quickly to meet the requirements of user. Generally this type of screen is still within your investment range and this is the type of screen suitable for office and home use.

Storage device

Don't buy 3.5-inch floppy drives: Here we don't talk about how cheap this type of storage device is, but we can guarantee at this point that this type of drive has become useless and is falling into oblivion. The last thing you have to do is make sure all your data has nothing stored on floppy disks. If so, transfer them to another storage device.

CD-R CDROM burners can be purchased: The types of writable CDs have become very cheap and have a storage capacity of about 700MB and are very long-lasting. The only problem here is that the types of drives that can burn DVDs with huge storage capacity are slowly taking over the market and you may end up switching to these drives and throwing CD-R discs. go away.

Should buy the small flash drive: In our subjective opinion, this is the invention that we liked most in the last 10 years. Types of flash drives have turned data into 'portable data' that can help us move data easily and quickly. But the type of floppy disk also has the same ability to move like this but the storage capacity will certainly not be as flash drive type. Currently there are flash drives with capacities up to GB and very compact.

System

Do not buy cheap PCs: Cheap computers only save you investment costs but sometimes cause you lots of sessions. These systems sometimes lack important components such as separate video cards or CD-R / DVD-ROM drives - you can only get one CD-R or CD-ROM drive. Not only that, but the storage capacity or screen is often very limited. The same situation occurs with CPUs because these systems often use inexpensive CPUs that lack many important features. Finally, these systems often have poor operating speeds to your expectations, they are mainly used for Internet access, instant messaging or simple office tasks.

Can buy cheap laptops: These types of computers are often in the same condition as low-cost desktop computers, but they save space when used and can be carried away. everywhere. So you can buy these systems also ok.

Should buy a well-equipped desktop or laptop: If you are planning to buy a desktop computer (PC), you should take advantage of buying the hardware as much as possible: buy those The hard drive has a large storage capacity - at least 80GB, with a large amount of RAM - up to 1GB and a graphics card of about 128MB with an LCD screen. If it is a laptop, it is recommended to buy powerful and light and powerful notebooks with 802.11g wireless connectivity, dual-layer DVD burner, wide screen and hard drive capacity as well as enough RAM Great to serve all your work requirements.

Digital camera

Do not buy digital cameras below 3-megapixels: Be aware that even mobile phones now have integrated digital cameras with resolution. A digital camera is really a camera that must have a large lens and has to be much more functional than a camera of mobile phones, at least 3-megapixel resolution.

Cameras with a resolution of 4 to 5-megapixels can be purchased: Camera types at this level of resolution have become too popular in the market. Not only that in the market, there have been many types of cameras with a resolution of between 6 and 8-megapixel. But you can choose for these types of cameras if you're still interested in price.

Buy 6- to 8-megapixel SLRs: Digital SLRs give you maximum control over the photos you take. Not only that, these cameras are relatively easy to use and cost not much higher than other cameras.

Mp3 player

Don't buy MP3 music players with 256MB flash drives: These MP players are really bad, but they are very cheap - usually under $ 50, but the capacity is very limited. You can store about 50 slightly better songs. Certainly a sound quality thing will not guarantee.

You can buy 1GB MP3 players: Music players like iPod are quite good for those who prefer to listen to music, and these types of music players also contain many songs along with other good features. impressive like display screen, recording capability or listening to FM radio .

Buy 4GB music players: iPod nano music player is a great choice for those who like to listen to music with really great features. Shop for yourself like that to satisfy your taste.
