Megabits or Megabytes Per Second

Megabits or Megabytes Per Second

So is it Megabits or Megabytes?

I have been perplexed for sometime as to why www.ozspeedtest.com¬†and OOKLA’s¬†www.speedtest.net¬†presented such different results.

…8Mb/s sounds 8 times better than¬†1MB/s…

It seems that the reason for this is that Oz Broadband Speed Test works upon a result of Decimal megaBYTES per second 

 

where¬†OOKLA’s Speed Test works upon a result of Decimal¬†MEGABITS per second.

So what are Bits and Bytes?

Well in essence¬†Bits are¬†like an atom, the smallest unit of storage for digital data and¬†Bytes are a¬†groupings of 8 bits! It’s really that simple!

So why present different units measurement?

Well that answer has no definitive answer beyond what would appear to be marketing and the ease at which we the consumers can be bamboozled.

…so it’s all in the case of the b’s “b/B”¬†but unless they are side by side you would not even tell…

You see Megabits per second is¬†Mb/s¬†and Megabytes per second is¬†MB/s¬†so it’s all in the case of the b’s “b/B”¬†but unless they are side by side you would not even tell.

When it all boils down data is most commonly¬†rated in MB (Megabytes) and most commonly ISP’s rate their speed in Mb (Megabits), but why, oh why, oh why, not just use one unit of measurement?

Because 8Mb/s sounds 8 times better than 1MB/s.

MB Mb

Most people who sign up for high-speed internet are thinking ‚Äúmegabyte per second‚ÄĚ when they say ‚Äúmegs a second.‚ÄĚ As Ron Stauffer in the US states on his blog in relation to this matter “I think¬†there really is something dishonest about the way the telecom companies are treating this‚ÄĒthey‚Äôre counting on their customers to be ignorant, in order to sell their products at what¬†sounds like a better deal than that it really is!” and I agree. There is no good reason for ISP’s to clear this issue up because the confusion feeds their ability to baffle and bullshit the greatest majority of consumers.

Kudos to¬†Ron Stauffer¬†for his story on¬†Your Internet Speed Explained: Megabits vs. Megabytes. While we both stumbled upon the real meaning of¬†Megabits V’s¬†Megabytes on a tech call hopefully if you have stumbled upon this you can create you own story referencing Ron and this post and make it easier for people globally to break through the Carrier BS and find the truth that lies beneath in the world of internet provision.

 

Bits and Bytes

Bits and Bytes

Bits and Bytes

At the smallest scale in the computer, information is stored as bits and bytes. In this section, we’ll look at how that works.

Bit

  • Bit, like an atom, the smallest unit of storage
  • A bit stores just a 0 or 1
  • “In the computer it’s all 0’s and 1’s” … bits
  • Anything with two separate states can store 1 bit
  • ¬†-Nick’s tennis racket example
  • Chip uses areas of electric charge as 0/1 states
  • Hard drive uses spots North/South magnetism 0/1 states
  • A bit is too small to be much use
  • Group 8 bits into a byte

Everything in a computer is 0’s and 1’s … what does that mean? The bit stores just a 0 or 1 .. it’s the smallest building block of storage.

Byte

  • One byte = grouping of 8 bits
  • e.g. 0 1 0 1 1 0 1 0
  • One byte can store one letter, e.g. ‘A’ or ‘x’

How much exactly can one byte hold?

How many distinct patterns can be made with 1, 2, or 3 bits?

Number of bits Distinct Patterns
1 0 1
2 00 01 10 11
3 000 001 010 011
100 101 110 111
  • 3 bits vs. 2 bits
  • Consider just the leftmost bit
  • It can only be 0 or 1
  • Lefmost bit is 0, then append 2-bit patterns
  • Leftmost bit is 1, then append 2-bit patterns again
  • Result … 3-bits has twice as many patterns as 2-bits
Number of bits Distinct Patterns
1 0 1
2 00 01 10 11
3 000 001 010 011
100 101 110 111
  • In general: add 1 bit, double the number of patterns
  • 1 bit – 2 patterns
  • 2 bits – 4
  • 3 bits – 8
  • 4 bits – 16
  • 5 bits – 32
  • 6 bits – 64
  • 7 bits – 128
  • 8 bits – 256
  • Mathematically: n bits yields 2n patterns (2 to the nth power)

One Byte – 256 Patterns

  • Need to know:
  • 1 byte is group of 8 bits
  • 8 bits can make 256 different patterns
  • How to use the 256 patterns?
  • How to store a number in a byte?
  • Start with 0, go up, one pattern per number, until run out of patterns
  • 0, 1, 2, 3, 4, 5, … 254, 255
  • One byte holds a number 0..255
  • i.e. with 256 distinct patterns, we can store a number in the range 0..255
  • Code: pixel.setRed(n) took a number 0..255. Why?
  • The red/green/blue image numbers are each stored in one byte

Bytes

  • “Byte” – unit of information storage
  • A document, an image, a movie .. how many bytes?
  • 1 byte is enough to hold 1 typed letter, e.g. ‘b’ or ‘X’
  • Later we’ll look at storage in: RAM, hard drives, flash drives
  • All measured in bytes, despite being very different hardware
  • Kilobyte, KB, about 1 thousand bytes
  • Megabyte, MB, about 1 million bytes
  • Gigabyte, GB, about 1 billion bytes
  • Terabyte, TB, about 1 trillion bytes (rare)

The space that data takes up in the computer is measured in by the “byte”. One byte is big enough to hold a single typed letter, like ‘a’. Here we’ll look at storing data in RAM memory and in persistent storage like a hard drive. All of that storage space will be measured in bytes. We’ll look at byte arithmetic in more detail later.

Bytes and Letters – ASCII Code

  • ASCII is an encoding representing each typed letter by number
  • Each number is stored in one byte of space in the computer (0..255)
  • A is 65
  • B is 66
  • a is 96
  • space is 32
  • “Unicode” is an encoding for chinese, greek, arabic, etc. languages, typically 2-bytes per “letter”
32 space

Typing, Bytes, and You

  • An example of bytes in your daily life
  • When you type letters on your phone or computer
  • Each letter is stored as a number in a byte, as below
  • When you send, say, a text message, the numbers are sent
  • Text is quite compact, using few bytes, compared to images etc.

I-Launcher & PC Backup by Samsung

I-Launcher & PC Backup by Samsung

Why was it so hard to find?

So finally after a few months of getting my new samsung NX300M camera I finally decided to sit down and read the manual as I had hit a brick wall being a typical bloke and having had worked out features I could on my own.

nx300m…hundreds of different search queries I finally managed to track down a link…

The first thing I realised was that photograph backup from my dslr to my pc could be automated, it was then that I realised that I was missing 1 essential ingredient! The cds that came in the box and hence my search online began.

After reading what seemed like hundreds of blogs and entering hundreds of different search queries I finally managed to track down a link to enable you to download I-Launcher & PC Backup by Samsung for the Samsung nx300 series.

Being a lover of Samsung it’s a little disappointing that this kind of resource is not easily searchable and downloadable by Samsung however if you found this post and you reading it you too now I have a solution hopefully easier in the journey it took me to find the link we all need.

Once you download a I-Launcher & PC Backup by Samsung you’ll be able to upgrade the firmware and¬†not only your camera but also the integrated lens¬†software as well.

I hope you found this helpful and have fun enjoying your samsung dslr I know I have.

A big thanks to the websites that led me to a resolution especially DP Review and Samsung NX @ Heroku App from whom the following content was made available.

Download I-Launcher & PC Backup by Samsung + DNG Converter, Movie Converter and Remote Studio Download. Factory Software for if you loose your discs from the sales box or your purchase a Samsung NX Series Camera and simply need the software from the box.

Eclectymmetry

Eclectymmetry

Dot connecting, intuition, perceptiveness are all words that come close the to Eclectymmetry, however none of them truly embodies the phenomenon of finding symmetry within the eclectic.

Eclectymmetry (or eclectic symmetry) is to derive an idea, style, concept or taste from a broad and diverse range of sources by aligning the similarities or exact correspondence between different influences, factors and considerations.

The ability to find symmetry within the eclectic.

Have you ever wanted to create a word? I just created a word and that word is, Da Dadada, Eclectymmetry! The thing is creating a word is easy but how do you get it recognised? How do you get it in the dictionary?

The simple answer is Lexicographers!

Lexicographers¬†are people who specialise in the theory and practice of dictionary making. Their chosen profession is that of Lexicography. To find your nearest or most relevant¬†lexicographer for your needs you will need to refer to the Wikipedia –¬†List of lexicographers.

There are some great blogs and info on the web about how to get a word formally recognised or you can simply visit modern services like Urban Dictionary or if your word is more like slang you can use a service like The Online Slang Dictionary.

A Parents Job

A Parents Job

A parents job is to do what they believe is right, to do it with love and to do it to the best of their ability. I have failed, I have floundered, I have stuffed up monumentally at times but what sets me apart from so much of the world is that I can own those mistakes allowing me to be open to the fact that what I think is right today, may just seem wrong tomorrow. Open your mind, accept you are vulnerable and start to grow today..
