Cores of Processor & Misconception about i3, i5, i7

The term core memory is a leftover from an early form of random access memory (RAM). Magnetic core memory  was first patented in 1947 and was used in early computers through the 50s and 60s. According to Wikipedia’s article, magnetic core memory was replaced by integrated silicon RAM chips in the 1970’s. Unlike modern silicon RAM, core memory was non-volatile — it retained its contents indefinitely without power.

multi-core processor is a single computing component with two or more independent actual processors (called “cores”), which are the units that read and execute program instructions.

Intel introduced a new naming scheme for its new Core processors. There are three variants, Core i3, Core i5, and Core i7, but the names no longer correspond to specific technical features like the number of cores. Instead, the brand is now divided from low-level (i3), through mid-range (i5) to high-end performance (i7), which correspond to three to five stars in Intel’s Intel Processor Rating as opposed to the entry-level Celeron (one star) and Pentium (two stars) processors.

For my curious friends !

  • Core i3 has 2 cores !
  • Core i5 has 2 or 4 cores !
  • Core i7 has 2,4 or 6 cores !

Now the question is how i3 is efficient then core 2 duo ?

Technically there are many differences but shortly what makes the big difference is the cache .

  • core i3 max cache = 4mb L3
  • core i5 max cache= 8mb L3
  • core i7 max cache =12mb L3

Processor earlier then i3 used L2 type cache .

DELETE YOUR PC DATA PERMANENTLY

Most people have some data that they would rather not share with others – passwords, personal information, classified documents from work, financial records, self-written poems, the list continues.
Perhaps you have saved some of this information on your computer where it is conveniently at your reach, but when the time comes to remove the data from your hard disk, things get a bit more complicated and maintaining your privacy is not as simple as it may have seemed at first.
Your first thought may be that when you ‘delete’ the file, the data is gone. Not quite, when you delete a file, the operating system does not really remove the file from the disk; it only removes the reference of the file from the file system table. The file remains on the disk until another file is created over it, and even after that, it might be possible to recover data by studying the magnetic fields on the disk platter surface.
Before the file is overwritten, anyone can easily retrieve it with a disk maintenance or an undelete utility.
There are several problems in secure file removal, mostly caused by the use of write cache, construction of the hard disk and the use of data encoding. These problems have been taken into consideration when Eraser was designed, and because of this intuitive design and a simple user interface, you can safely and easily erase private data from your hard drive.

Eraser is an advanced security tool for Windows which allows you to completely remove sensitive data from your hard drive by overwriting it several times with carefully selected patterns. Eraser is currently supported under Windows XP (with Service Pack 3), Windows Server 2003 (with Service Pack 2), Windows Vista, Windows Server 2008, Windows 7 and Windows Server 2008 R2.

Windows 8 : Bye Start button?

With Microsoft’s latest operating system looming large on the digital landscape – set for a public beta launch at the end of the month – casualties are beginning to emerge.

It turns out that the launch of Windows 8 could see Microsoft’s iconic Start button going the same way as Clippy.

Now a mainstay of personal computing, the Start button was launched 17 years ago amidst a massive advertising campaign featuring the Rolling Stones song “Start me up“.

With Windows XP/Vista and 7 installed on a huge portion of PCs worldwide, the Start button has become a design icon that is effectively synonymous with the Redmond based software giant.

Sadly in Windows 8, rumours are that Microsoft has decided to kill off the Start button, with the space to be occupied by what is being called a “hot” corner.

In essence this will equate to moving the mouse pointer (if on a PC) into the corner which will fire up the new full-screen Metro-style start screen. Tablet users will be able achieve the same result by flicking their finger to the same bottom left corner of the screen.

Windows 8 will perhaps sport the most radical interface overhaul since Microsoft jumped from Windows 3.11 to Windows 95, and killing off the Start button will arguably free up more on screen real-estate.

From a cursory play with the new interface at Microsoft’s CES stand recently, the new interface may have impressed, but it is likely that many long term Windows users will find it baffling.

For first time users the news is potentially worse as there’ll be no visual cues for returning to the full-screen start menu of Microsoft’s newly minted Metro interface.

With the Windows 8 public beta due out in a couple of weeks, the Start button could possibly reappear by then, rumours are that die hard windows users shouldn’t get their hopes up.

So will there be a wake held for the soon to be deceased Start button? Will there be much of an outcry?

This remains to be seen, but the good news is that the Windows key on the keyboard of most PCs will still have the same function as it has today under Windows 8 and will pop up the Start screen – which should at least provide a solution for some frustrated users.

Adobe no more supports mobile Flash

beast image

Did Apple kill Adobe’s mobile Flash? That is the question many asked this week after Adobe announced that it would end development of Flash for mobile devices.
Many observers were not surprised by the announcement, which came a day after the company announced it would cut 750 jobs.

Don Reisinger of eWeek compiled a list of reasons why Adobe lost the mobile Flash battle, which identified the resistance from Apple and the success of iPhones and iPads as the main reasons.

The Guardian said that with the news, it was Steve Jobs who had had “the last laugh”.

Elsewhere, Jason Perlow of ZDNet’s Tech Broiler blog argued that without a focus on the rising mobile market, Adobe Flash is “irrelevant”.

PCWorld’s Daniel Ionescu asked if “anybody will miss Flash on their mobiles?” and pointed out that “iOS users have been living Flash-free for more than three years”.

Still, some saw Adobe’s move as a step in the right direction. Matt Peckham of Time’s Techland wrote that it takes “guts to do the right thing”.

“Adobe deserves our plaudits, for doing something I’d wager Steve Jobs never would have (whatever his claims about the web), had Cupertino been the proprietor of Flash and not the folks from San Jose,” Peckham added.

But for Bill Ray of the Register, the announcement shows where Adobe plans to head with its future developments of HTML5 tools.

He wrote: “This announcement has much more to do with Adobe seeing that there’s no future in selling tools for streaming video, but there is a decent future in selling tools to create, and control, digital content.”
