What is a high speed usb host controller?

A hi-speed USB host controller is basically a 2.0 usb port that replaces the 1.0 usb ports that were created a couple years ago. It's faster than the 1.0 usb ports, its still the same shape, but 2.0 has more power and better hardware incorporated. USB 3.0 is also available that is much faster than 2.0.
That's the general term for USB2.0, it operates much more faster than USB 1.1 which is know as non Hi-speed.

To find out if you have Hi-speed USB2.0 capable hardware:

In Window XP:"Right click my computer, then "manage", select device manager and scroll down to USB controllers. Click the + then look for the word "Enhanced" in either of the host controller listed. If there's 1 with Enhanced, then you have USB2.0 capable hardware.

See the related link for more info about USB1.1 and USB2.0

Computer Memory

How many megabytes are in a gigabyte?

Standard definitionOfficially, there are 1000 (103) megabytes (MB) in a gigabyte (GB). So 500MB would equal 0.5 GB.

This definition is used in hard drives, portable memory drives (memory cards, USB drives), DVDs, Blu-ray disks, and most measures of performance. Some software (such as Mac OS X and the Linux kernel) uses this definition when displaying file and disk sizes.

MB stands for megabyte. Mb with lowercase b is ambiguous, as it has been used for both "megabyte" and "megabit". Writing megabytes as MB and megabits as Mbit avoids any confusion.

Memory manufacturer definitionAnother definition is used by memory manufacturers and some software, like Microsoft Windows. They use 1024 (210) megabytes per gigabyte, but this is more properly called a gigabinary byte(GiB), sometimes contracted to gibibyte.

Using the non-standard definition:

  • 1 megabyte (MB) = 1024 kilobytes (KB)
  • 1 gigabyte (GB) = 1024 megabytes (MB) or 8192 megabits (Mb)
  • 1,000 megabyte (MB) = 1 gigabyte (GB)
  • 1,024 mebibyte (MiB) = 1 gibibyte (GiB)
  • 1 megabyte = 8 megabits
  • mega- = 1,000,000
  • giga- = 1,000,000,000
  • mebi- = 1,024 × 1,024 = 1,048,576
  • gibi- = 1,024 × 1,024 × 1,024 = 1,073,741,824

Web Browsers

What is a browser cookie?

Browser CookiesAn HTTP cookie is a packet of information sent by a server to a World Wide Web browser and then sent back by the browser each time it accesses that server. HTTP cookies are used for user authentication, user tracking, and maintaining user-specific information such as site preferences and electronic shopping carts.

Cookies have been of concern for Internet privacy, since they can be used for tracking the browsing of a user. As a result, they have been subject to legislation in various countries such as the United States, as well as the European Union. Cookies have also been criticized because the identification of users they provide is not always accurate and because they can be used for network attacks. Some alternatives to cookies exist, but have their own drawbacks.

On the other hand, cookies have been subject to a number of misconceptions, mostly based on the erroneous notion that they are computer programs. In fact, cookies are simple pieces of data unable to perform any operation by themselves. In particular, they are neither spyware nor viruses, despite the detection of cookies from certain sites by many anti-spyware products.

Most modern browsers allow users to decide whether to accept cookies, but rejection makes some Web sites unusable. For example, shopping baskets implemented using cookies do not work if cookies are rejected.

More Information:

A cookie is a piece of data that can be stored in a browser's cache. If you visit a web site and then revisit it, the cookie data can be used to identify you as a return visitor. It remembers the visited pages in your system each and every time by holding data for a single web session, that is, until you close the browser data.

A cookie is a bit of electronic information that can be placed on your computer when you visit a Web site to track what you look at there, recognize you when you return, and in some cases, track where else you go on the Internet. You can set your online preferences to prohibit, limit, or let you know about "cookies" that a Web site places on your computer.

Most cookies are not bad things - you may get the impression that cookies are spying devices ("track what you view") - but for the most part they are harmless and quite useful; for example, a cookie might store your login information for a website or a forum, allowing you to visit that website/forum without logging in again each time. This is all the Wiki s cookie does.

What does seeding mean in torrent?

The people sharing & connected to each other using the bit-torrent protocol are split into 2 categories. SEEDS(uppers) & LEECHERS(downloaders) In the begining while downloading a torrent for the first time you are a leecher because the download hasn't completed. When it completes you switch to a seeder and dedicate that stream to simply uploading. The more seeds available the faster the download.

Seeding is the process of connecting to a torrent when you have a complete file.

Yes it is important to seed 1 to 1. The more seeders there are on a torrent the faster the torrent is. You are not downloading the torrent from the actual site you get it from. You are downloading it off another user that has it on their computer.

Let's say someone uploads a torrent to a site and that person seeds at 100kbps. At first every single leecher is trying to get the file from the uploader which if there are 10 leechers then each leecher is approximately getting the file at 10kbps.

Let's say the 10 people finish downloading the torrent from the uploader. Each also is seeding at a speed of 100kbps.

That means the total speed of the torrent after the 10 get done downloading the file is 1100kbps. Because 10 are seeding at 100kbps and the original uploader is seeding at 100kbps. So if there are 11 more leechers getting the file now each of those leechers are approximately getting the file at 100kbps instead of 10kbps because there is a 1 to 1 ratio per seeder & leecher.

If everyone just downloaded the file from the uploader and stopped seeding without seeding the torrent 1:1 then the uploader will always be stuck seeding. Which the speed of the torrent will hardly go up because the leechers will always outnumber the seeder.

So it is important to seed back at least what you take. So if you download a file that is 1GB then seed back 1GB. That is why it is called FILE SHARING. People are considerate enough to share their stuff you can repay them back by seeding back what you take so others can enjoy it as well.

".com" is the most common and most recognized domain suffix. It stands for "commercial" and is used by mostly commercial websites. However, anyone who wants to register a domain name can register a name ending in .com, whether their site is going to be used for commercial purposes or not.

dot-com represents a company that operates its business on the Internet using a URL that ends in `.com' (com means commercial).

This was initially used when the internet was opened to commercial users, where it was previously only used (and paid for) by government (.gov), military (.mil), or educational (.edu) users. Non-commercial groups were also authorized under the .org top-level domain.
If by com you mean the ane of a URL like, it means company. Commercial organization
".com" is the most common and most recognized domain suffix. It stands for "commercial" and is used by mostly commercial websites. However, anyone who wants to register a domain name can register a name ending in .com, whether their site is going to be used for commercial purposes or not.

While .com is the most common of all domain suffixes, .net and .org are also popular. ".net" stands for "network," while ".org" stands for "organization." Again, these domains can be registered by anyone regardless of their intended use. For more information on domain suffixes, including those from countries around the world
having .com at the end of a URL means that it is either a communications or commercial website.
On the Internet, the .com you see after websites and email addresses stands for "commercial". The .net you may see stands for "network". And the .org you may see stands for "organization". Hoped that answered your question!
".com" is a commercial Internet Top Level Domain (TLD). This is an open TLD, meaning that any person or entity is permitted to register.
Merely an address for the web page.

How many MB are in 18.2 GB?

This depends on what you are talking about. The standard definition of 1GB is 1,024MB. So 18.2GB = 18636.8MB.

However, Hard Drive Manufactures round this to 1000MB in a GB, so you only get 18200MB.

by putting an i in the middle (e.g. Mib) you specifically define the 1,024 step, not the 1,000 rounding (so 18.2GB = 18,636.8MiB and 18,636.8MB and 18,200MB)

By the way, MiB is Mibibytes, whereas MB is megabytes!

How many GB is a pen drive 983 MB?

983MB would be .983GB.

it's likely that this is a 1GB pen drive and two factors are affecting its' size display

1) formatting takes a slight area of space, reducing the size slightly


2) Windows incorrectly displays the units 'GiB'/'MiB' as 'MB'/'MiB'. device manufacturers use the latter (base 10) while most operating systems display the former (base 2)

Why would your computer freeze up after defragmenting the hard drive?

Moved FilesOne reason may be because files were moved and your computer needs to be restarted cause the computer was reading the files and they all of a sudden moved. Physical FaultsOne possible reason for this is that your hard disk is developing physical faults. Sometimes these faults may not be picked up by tools like ChkDsk however chkdsk is a good place to start I would advise using the /r option. There are other free tools around that can help you identify Hard disk Faults like "Drive Fitness Test". If any of these tests show that the hard disk does have faults it should be replaced as soon as possible. Software is available that will enable you to clone the faulty drive onto a new one.

put your computer in SAFE MODE.THEN DEFRAG.

Check your hardware in device manager and see if there are any conflicts,(yellow ? marks), beside your display adapter, your monitor, and your sound drivers), sometimes a driver can become corrupt and you may need to update it. Also The defrag could have defraged a file in your registry that is no longer used, I recommend buying Registry Mechanic, this will fix any errors in your registry that can also cause freezing. One last thing, go into safe mode, and do a scan on your hard drive for errors, make sure before you do the scan make sure the box is checked for,"automaticaly fix errors". Then when that's all done, do a defrag in safe mode.

Like you I have had problems defragging, but I think that in my case it was something wrong with the defragger, as when i did it 2 weeks ago, then my computer crashed doing this, i restarted, 'Cannot Find Hard Drive', so then it went to a comp shop they fixed it, did disk defrag again, then computer restarted with the same problem, then it started to go through, 'Used Clusters' 'Unused Clusters' 'Bad Clusters' then here it takes forever to do then the computer frooze, so i turned it off, went and bought a new computer


Your problem is either a driver, harware or heat issue. Try updating chipset drivers with the original that came with your motherboard if it doesint work update with windows update to get the a signed driver, check to see if your hdd is running hot if you cant touch it get rid of it, update your bios if this occurs when you have just changed your hdd, disable the s.m.a.r.t function in bios if your hdd is older than 9 years old and lastly has i have seen enough before your video card is failing, change it.

Declaration of Independence

What is Evidence of bias for the Declaration of Independence?

One obvious form of bias is that although it admitted that "all people are endowed with certain Rights by their Creator, among them Life, Liberty and the Pursuit of Happiness", slaves were still widely used and treated inhumanely until almost 200 years after the Declaration was written. This went the same with women, although they were treated unfairly to a lesser degree compared to slaves.

What is the difference between computer science and information technology?

At the most basic level, Computer Science is a "Hard" Science, well grounded in what is now known in the field of Mathematics as Information Theory. Computer Science (as a field) is concerned with developing new ideas around the use and design of computing systems, and with the mathematical concepts of computation and information.

Information Technology, on the other hand, is a practical Engineering discipline, concerned with implementing solutions to practical problems using current-day technology.

What is the difference between a CD-R and CD-RW?

RW stands for ReWritable. With a CD-R you can't put anything on it more than once. You add songs to it once and that's it. It is how it is, you can't do anything else with it. You can reuse a CD-RW. Say I had a song on there, but it messed up. I can either find it in my computer and delete the song and then put the right one on it. Or i can add the right one along with the wrong one.
