Netbook vs Laptop

Posted by: admin | Comments Comments Off

Going back several years, the one question which was repeatedly asked of me was, should I buy a laptop instead of a desktop computer? Whilst there is no definitive answer, as each person's needs are different, the answer has probably changed from 80% NO to 80% YES. The reason for this is the narrowing gap between desktop and laptop PCs in terms of performance, reliability and storage capacity.

Today we have a stand-off between netbook and laptop computers as people discover the possibility of going even more portable. Let us's look as the main considerations in the Netbook vs Laptop debate.

Performance

Laptops are almost the new desktop, with processor speeds increasing as manufacturers find new ways to squeeze extra performance from smaller components. Without getting too technical, laptops have a huge advantage in the performance stakes. I'd go as far as to say that if you want to use a computer for processor-intensive tasks, a netbook is currently not a good option.

Screen and Keyboard

Because of their smaller size, netbooks tend to have smaller keys and screens. This changes from model to model. Laptops for the most part, have standard sized keys with screens of standard desktop monitor sizes. If you have large hands and do a lot of typing, netbooks can become annoying very quickly. Also, if you need to have lots on the screen at once, laptops have the advantage with their greater resolutions and screen size.

Size

Netbooks are in effect mini laptops and so have a size advantage where portability is concerned. They tend to be lighter due to this, therefore if you intend on using one for traveling with, they are ideal. Laptops, on the other hand, are considerable in their weight and size in comparison.

Connectivity

Most netbooks tend to have a couple of usb ports and wireless networking. They do nottend to have cd/dvd drives. These days laptops have dvd re-writers and usually 3 or 4 usb ports as well as vga output for displaying on an external monitor. If you want to watch your dvd collection on your new computer a laptop has the distinct advantage.

Cost

The price of a netbook is relative to functionality and usefulness as is that of a laptop computer. I'd say that presently, a laptop has greater scope for growing with the user's needs and therefore offers better value. If cost is the ultimate factor in choosing between the two, I would go for a cheap laptop vsa netbook. If you just want to surf the net and keep up to date with friends on Facebook a netbook is a very good option.

Storage

Netbooks tend to have less storage capacity than laptops although this has improved over time and will probably continue to do so. If you want to store large amounts of videos and photo albums without using external storage, a laptop again has the major advantage.

Battery life

With it's small footprint, lack of dvd and power efficient processors (generally) netbooks win hands down in the power consumption efficiency stakes.

The bottom line is, you really have to be honest with yourself as to how you'll use the computer. I'd say that the only real reasons to have a netbook over a laptop are portability and battery life. If you make a list of the above points when preferring you willhave a good idea of what to compare when shopping.

Camcorder Recording Methods and Technology

Posted by: admin | Comments Comments Off

Over the years, camcorders have evolved from tape (which has spanned many decades), to DVD, and more recently to Harddrives(HDD) and Flash Memory.

[1] Tape Camcorders - The oldest technology has evolved from reel to reel, VHS, VHS-C, 8mm, Hi8, and finally to today's best tape technology, the MiniDV tape. The latest MiniDV tapes are very small in size, and hold about 1 hour of recorded video in either standard definition, or high definition (using HDV compression). Most professional camcorders still use tape. Tape does have one advantage, that is that the recorded tape is an archive or backup of your video. So even if you transfer the video to your computer, and the computer crashes, you still have your tape. The disadvantage of MiniDV is that the camcorder will be larger, and you have to go sequentially through the entire tape (like VHS tapes) to get to a scene. The quality of the recording though is excellent and good for editing once its transferred to a computer.

[2] DVD Camcorders.- This type of camcorder was designed mainly for convenience. These type of camcorders for a brief time were top sellers. Their appeal was that you could record video to a Mini DVD that could be played directly by your home DVD player. Standard Mini DVDs only hold about 20 minutes of video at best quality. Transferring the video for editing is not ideal, and you may lose some quality. This type of camcorder is now in decline as less models are available and it is not a top seller.

[3] Harddisk (HDD) Camcorders - These type of camcorders which were introduced a couple of years ago, use a tiny computer harddrive (similar to what is in an iPod Classic) to record video. The advantage of this type of recording method is the huge storage potential. A typical high definition HDD camcorder can hold at least the equivalent of 10 MiniDV tapes. So they are adequate for even the longest filming events or vacations. The main disadvantage of an HDD camcorder is that there is no archival copy of the footage. Once you transfer the video to your computer, you erase the camcorder to record again. It is recommended that you make backups of your video on external harddrives so if your computer crashes, you don't lose your video. HDD camcorders can also eat more power than a Flash Memory camcorder.

[4] Flash Memory Camcorder - This is the latest and most popular type of camcorder. These camcorders record to memory cards (Typically SD, SDHC, and Memory Stick). These are the same type of cards that digital cameras use. The advantage of this type of camcorder is smaller size, better battery life, and no moving parts to record the video. Flash memory is now in small and cheap camcorders, as well as advanced models with bigger imaging sensors and lenses. For high definition they use the new AVCHD compression. The disadvantage of this type of camcorder is the same as harddrive camcorders. If you erase your memory cards to re-use, then you need to make backup copies of your video from your computer.

[4] Dual Flash Memory Camcorder - This is exactly like the flash memory camcorders, except that they have built-in memory (typically 16gb to 64gb as of this writing). You have the option of using the internal memory or memory cards.

The future of camcorder recording technology appears to belong to flash memory and dual flash memory. This should be the standard for recording video for many years to come, just as video tape was the standard for decades.
