Written on July 25th, 2012 by sanklpno shouts

एप्पलले बुधबार बिहानबाट म्याक कम्प्युटरमा नयाँ अपरेटिङ सिस्टमको बिक्री थालेको छ। २० अमेरिकी डलर पर्ने माउन्टेन लायन नामको यो अपरेटिङ सिस्टम राखेपछि कम्प्युटरमा पनि आइफोन र आइप्याड जस्तै विशेषता थपिनेछ।

 एप्पलको यो अपरेटिङ सिस्टममा माइक्रोसफ्टले आउँदो अक्टोबर २६ देखि बजारमा ल्याउन लागेको विन्डोज ८ सिस्टमसँग मिल्दोजुल्दो छ।

माउन्टेन लायन डाउनलोडबाट मात्रै बेचिनेछ। लायन र स्नो लियोपार्ड अपरेटिङ सिस्टममा मात्रै यो संस्करण अपग्रेड गर्न मिल्छ। जुन ११ मा वा त्यसपछि किनेका म्याकहरुमा निःशुल्क अपग्रेड गर्न मिल्छ।

नयाँ ओएसमा फेसबुक, ट्विटर, फ्लिकर जस्ता सामाजिक सञ्जालसँग राम्रो इन्टिग्रेसन गरिएको छ। एजेन्सी

Actual size of a 500GB hard drive

Written on July 25th, 2012 by sanklpone shout

Actually, the 1000 vs. 1024 thing does not *really* apply to hard drives, only memory.

When discussing memory, a “gig,” is really a Gibibyte (1024^3 bytes, abbreviated GiB), not a Gigabyte (1000^3 bytes, abbreviated GB). Computers “think” in binary, so everything is numbers that can be factored only by 2.

This is *not* the case with storage. Manufacturers can make storage in any size — not just sizes factorable only by 2. So, a 500 GB hard drive is 500 Gigabytes (500 x 1000^3 bytes).

In theory — in practice, hard drives are rated by “size class.” So a 500 GB hard drive is in the 500 GB size class, which means *pretty close to* 500 GB.

To add to the confusion, most operating systems use the JEDEC standard definition of GB, in which a GB is 1024^3 bytes!

So, your 500 GB hard drive should have a size of

500,000,000,000 bytes.

Your OS will recognize it as a 465.7 GB drive, but, by that, it means

500,000,000,000 bytes

Because when your OS says GB, it really means GiB.

 

***************

This makes a gigabyte 1,073,741,824 bytes. Now if we compare that to the 1,000,000,000 bytes that the HDD manufacturers use,
you can see that there is over a 7% difference! Therefore Windows will report the hard disk as being approximately 7% smaller than the hard drive
manufacturer’s quoted size.

then don’t forget Another factor that can mean you have slightly less space on your HDD than quoted is because the file system that your computer
puts on the hard drive takes up space which is not available for use for storing data

How To Disable a USB Flash Drive (Mass Storage Devices Only)

Written on July 25th, 2012 by sanklpno shouts

Whenever you insert a USB flash drive into your computer, the flash drive is detected automatically by Windows and then opened. Here I am going to show you how to stop your USB Flash Drives Mass Storage Only through registry.

This trick can also be done through My Computer by using Device Manager but that one stops all the USB connections. This is not recommended.

So are you ready to start?

Here we go.

Click Start Menu > go to run command and type “regedit” without quotes. Registry Editor will open.

  1. Expand the HKEY_LOCAL_MACHINE folder then SYSTEM >CURRENT CONTROLL SET > SERVICES >USBstor, located at the left pane.
  2. Find “Start” in the right pane with the blue icon.
  3. Double click “Start”. A box titled “Edit DWORD value” will open.
  4. Write down “4” in the “Value Data” Field. Illustration 1.1
  5. Click OK and then close the Registry Editor.

Your USB flash drive is now disabled. Whenever you insert a flash drive, Windows won’t detect it and will not open it.

To enable it again, repeat steps 1 through 4 and then change the value to 3. The default value for enabling a USB flash drive is 3.

Note: Performing this trick will only Disable USB Mass Storage devices and will not affect other USB Devices such as USB Keyboard, USB Mouse, Scanner, Printer etc….always backup your registry to prevent losing your valuable data.
