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.

A 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 .

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.

China's Silicon Valley

Zhongguancun may be
hailed as China's most famous village by foreigners. Dubbed as "China's
Silicon Valley", the country's biggest high-tech park in west Beijing is
not only home to Chinese high-tech companies such as Lenovo, Baidu and
Sohu.com, it is also the China headquarters of world-renowned technology
companies such as Google, Microsoft and Intel.

As part of China's efforts to build an
innovative economy, the State Council, China's Cabinet, recently
approved a development plan called the Zhongguancun National Innovation
Demonstration Zone (2011-2020) that allows companies in the area to try
out new measures and pilot projects.

The plan, which includes a drive to
boost the total revenues of companies in Zhongguancun to 10 trillion
yuan ($1.8 trillion) in 2020 from 1.55 trillion yuan last year, is
designed to help the area become one of the world's most famous
technology hubs. The predicted income increase will come from increased
sales on the back of tax incentives for companies moving there and
research and development subsidies.

"Zhongguancun has entered a new phase of
development," said Yang Jianhua, deputy director of the administrative
committee of Zhongguancun Science Park. "I think in the next 20 years
Zhongguancun will have the three top technology industry clusters in the
world and will form a grouping of the world's top technology
entrepreneurs."

Zhongguancun's history can be traced
back to a crowded electronic avenue in the 1980s. Close to China's top
universities and national academies, China's biggest technology hub
first emerged as a small market for electronic components and devices
for technicians and researchers.

In October 1980, Chen Chunxian, a
researcher at the Chinese Academy of Sciences, founded a technological
development service department under the Beijing Society of Plasma
Physics in Zhongguancun, making it the first civilian-run scientific and
technological institution in the area.

I just bought another irresistible dedicated server offer from a reputable provider (although I have no use of it at the moment). The details of the mouth watering deal is

Intel(R) Core(TM) i3-2100 CPU @ 3.10GHz
4GB DDR3 Memory
500 Gig Sata hard drive
100mbit network
5 IPs

all that for just $49/mo

I got the hard upgraded to a 1TB Sata3 and memory (RAM) upgraded to a whopping 12GB (some one you may be surprised to see ONLY 12GB but for me, this is the heaviest system I have rented to date). I am planning to keep it running even though I have no use for it at the moment.
