File extensions

 1.What is a file extension?
a file extension is a suffix given to a file to indicate file format .

2.Main aspects of file extensions?

• Extensions are the way information is encoded.
• They are used according to file types.
• Different programs use different extensions.
• There are tons of extensions right know.
• Computers manage files according to their file extension.
• File extensions keep growing.
• File extensions are propietary (someone owns them and public.
• Usually the last three characters following a dot are the extension.
• Extensions can be hidden to spoof people.
• There are multiple extensions for text files in uncommon languages.

  3.How a file extension is related with digital information?
File extension is directly related to digital information because they determine the way digits (1´s and 0´s)
are arranged. Also they vary according to the file type and computers handle files different if they are in another format. 

4.What means encoding a text file with ANSI or
Unicode?

An ANSI text file only contains 256 characters so it doesn´t have on its table every character for every language but ANSI2(Double Byte) uses two bytes where the first one contains wich table should be used and the second which character is so multiple tables are used while Unicode uses 2 bytes for each character so  there are 65536 codes to be used and that  provides enough character codes to represent every character of most used languages around the world.

5.Most popular file extensions for word documents, images and sound.

Motorola Surfboard SB5101 vs Cisco-Linksys Cable Modem

motorola's modem has a stylish case that saves valuable desk space there's no need to use telephone lines and provides you up to 30mbits per second of upload speed and cisco does just about the same the only difference is that morola's is cheaper and doesn't come with integrated wireless

connection speeds

when ISPs refer to kbps they are not refering to kilobytes it's a measure of data trasfer speed. Modems, for example, are measured in Kbps.
One kbps is 1,000 bits per second and a Kb (kilobyte) is 1,024 bytes. Technically kbps, should be spelled with a lowercase k to indicate that it is decimal but almost everyone spells it with a capital K.
 A kilobit per second is a unit of data transfer rate equal to:

• 1000 bits per second or
• 125 bytes per second.

A megabit per second is a unit of data transfer rate equal to: 1,000,000 bits per second or 1,000 kilobits per second or 125,000 bytes per second. So if I had a 5 mbps connection i could trasfer up to 625000 bytes per second or 610 Kilobytes per second or 0.6 MB per second

Bit,Byte and Terabyte

Please Recycle

Recycling Discs ♻

Have you ever wondered why our planet is destroying?
If you want to be part of a solution I suggest you to join us because sometimes we throw things that can be reused so we could reduce global warming and save animals just by recycling stuff that is hanging around our house.
Compact discs are one good option to start being green because they are just everywhere and you do not need not classify them.

A great idea is to make a bin out of recycled cardboard to store the CD'S until its full so you take it to your local recycling facility and ask them where to leave them. Just think as this as a good action plus you can also make some extra money.
