What is the best memory buffer size to allocate to download a file from Internet? Some of the samples said that it should be 1K. Well, I need to know in general why is it? And also what's the difference if we download a small .PNG or a large .AVI?
For what it's worth, I tested reading a 1484 KB text file using progressive powers of two (sizes of 2,4,8,16...). I printed out to the console window the number of milliseconds required to read each one. Much past 8192 it didn't seem like much of a difference. Here are the results on my Windows 7 64 bit machine.
Use at least 4KB. It's the normal page size for Windows (i.e. the granularity at which Windows itself manages memory), which means that the .Net memory allocator doesn't need to break down a 4KB page into 1KB allocations.
Third, array data structure in C# occupies some bytes more than the content itself (it stores array size and other informations). If you allocate page size amount of bytes, using the array will switch page almost always!
In some cases you can find out (or know, or hack around in a debugger and hence find out albeit in a non-change-resistant way) the size of a buffer used by the stream(s) you are writing to or reading from. In this case it will give a slight advantage if you match that size, or failing that, for one buffer to be a whole multiple of the other.
When choosing the best free download manager for you, you'll want to start with considering how simple the download process is. Does it happen swiftly in a few steps, or is it an elaborate process that demands file decompressing and extraction?
Media previews and download scheduling are convenient features, but not all download managers offer this. Look out for privacy protection features and check whether the software comes with pesky adware.
The best free download managers provide the ability to organize, prioritize, and streamline your downloads. They provide stability over using a web browser to download files, especially several at once.
Its interface is simple and modern (if a little dark), and its accelerator can help you get your files 10 times faster. It does this by splitting each file into chunks, then downloading each one using a different server connection, making downloads not only faster, but also more reliable. If you're into music and movies you'll be delighted by its sequential setting, which lets you begin playing a file while it's still downloading.
It can crawl sites to download specific kinds of files, and you can choose to download only the bits of a ZIP file you actually want. For us, it's an exceptional program, and a true contender for the top spot.
It's really one for power users, with support for over 300 decryption plugins, automatic RAR extraction, password list searching and OCR to complete some of the captcha 'I'm not a robot' checks you encounter on download sites.
There are other things, besides the interface, that make JDownloader feel dated. You'll need the Java Runtime Environment to run it, and to be careful when installing it not to install the bundled adware. Beware, also fake 'download' buttons on the site; the actual download link is a line of text, not a button graphic.
We tested various free download managers to determine their performance. We looked at the ease of finding and download the manager, the download speeds, interface, learning curve, and privacy features.

Yes, it is possible to use streaming services (which of course is what the majority of non-DJs do for their music nowadays) as your day-to-day music source, even to DJ with. Indeed, in our DJ courses we recommend that every student DJ subscribe to a streaming service, if only for the purpose of music discovery. And DJing with streaming services is lots of fun and has its own advantages, too.
The first name most electronic music fans think of when it comes to buying music files is Beatport. Beatport offers a wide selection including the vast majority of underground labels, and a mind-boggling array of genres and sub-genres. The store is fun to shop in, with lots of DJ charts and other tools to help you sift and listen to music, including a pretty good preview player and the ability to make playlists before buying.
Prices have dropped over the years (they used to be sometimes prohibitively expensive), and Beatport has introduced lots of innovation including Beatport Streaming (that integrates perfectly with the store and DJ software), and even a browser-based DJ app. Thoroughly recommended for electronic music DJs, as it is definitely one of a kind and consistently a market leader.
Unlike Beatport though, Traxsource is purely a download store, with no non-store features to distract you. And with a decidedly anti-corporate/underground feel, if you miss shopping in real good independent dance music stores, this could well be your digital home. Naturally, the store sells all relevant formats, with AIFF and WAV as well as MP3s.
Qobuz is a French music company that is primarily a streaming service, which tries to differentiate itself from the competition with high quality music files, and deep curation. (When you use it as a streaming service, it provides sleeve notes and so on to make streaming a richer experience, especially for fans of classical and jazz, two areas it shines in.)
A UK-based digital download store that once was an innovator when it came to hi-res music (no MP3s here), 7digital is available in the US and the UK and non-EU markets, but curiously, nowadays not in Europe.

Construction projects require a large amount of data. To ensure that you have access to your data, ProjectSight requires that you perform an initial project download. Depending on your project size, this may take some time. When downloading a large project for the first time, we recommend the following:
Download your project at the end of the day. Connect your mobile device to a power source. Ensure that your device will have uninterrupted power all night. During initial project download and manual sync, if your device is connected to power or maintains a power level of 10% or more, the ProjectSight app keeps your device awake.
It is recommended that you customize your initial download settings to only download what you need to work offline. Unless you have customized your download settings, tapping Download on the Home Page will only download project records. Current and past drawing revisions, as well as project records' attachments and linked drawings will not be downloaded. If you are online, you can always download attachments or drawings on demand.
