We Bet You Don’t Know The Reason Why Keyboard’s ‘F’ And ‘J’ Keys Have Raised Ridges !!!

Did you ever look at the keyboard and thought why ‘J’ and ‘F’ keys have raised bumps on them?

Sometimes, the same is seen in case of ‘5’ key too. Don’t worry, it is not any kind of production defect, but in fact this is by design.


It is basically for ease of use!

For using this keyboard with ease, the keys have ridges, so that speed typing is possible, without having a look at the keyboard. These ridges help in positioning the fingers. They enable you to have a correct typing position and since the ridges are there on these 2 keys, the index fingers are placed on them.

Know the positioning

If the left index finger is positioned on the ‘F’ Key and if the right index finger is positioned on ‘J’ key, then other 3 fingers of left hand can rest on ‘A’, ‘S’ and ‘D’ and others can rest on ‘colon key’, ‘L’ and ‘K’. Both the thumbs must rest on space bar.

These improvements came in after June E Botich filed a patent in the year 2002. After this, all the keyboards came in with the same arrangement.

Here’s Why Hard Disks & Pen Drives Have Less Space Than The Promised Space!!!

Pen drives, hard disks come under the category of USB flash drive. USB flash drive is also known as USB drive or USB stick. It is a data storage device with an integrated USB interface which includes flash memory. Presently, pen drives and external hard disks have been part of our life just like smartphones. But have you ever checked that the pen drives storage capacity is different to that of the promised space by the manufacturer?

Yes, the storage space differs for sure. For example, let us take a 8 GB pen drive and after plugging it to your computer, you can see that only 7.46 GB space is available.



Then where is the rest of 0.54 GB ?

Scratching your head and cursing the manufacturer? Well, there is a trick used by the manufacturer here. Let me  explain it clearly.

A simple of math involved in this. Generally, every one of us knows that computers work using number 2 as the base. According to this the memory management will be :

1 Kilo Byte (KB) = 1024 Bytes

1 Mega Byte (MB) = 1024 Kilo Bytes (KB)

1 Giga Byte (GB) = 1024 Mega Bytes (MB)

8 GB = 1024 * 8 = 8192 MB

But pen drive and hard disks manufacturers consider it as base 10. i.e

1 KiloByte (KB) = 1000 Bytes

1 Mega Byte (MB) = 1000 Kilo Bytes (KB)

1 Giga Byte (GB) = 1000 Mega Bytes (MB)

8 GB = 1000 * 8 = 8000 MB ( approximately equal to 7.81 GB)

and the rest of the memory (approximately 0.35GB ) is reserved for data sector and system files for better performance.

As the device memory capacity increases, we lose more amount of space. The table below shows some shocking figures.



Manufacturers are actually not cheating anyone in this whole drama. In fact, they mention this on the box of hard disks and pen drives. Take a close look at your hard disk boxes.
