Google Greasing Chrome OS for Launch


Google’s planned operating system, is just about ready to hit the market, according to reports. The OS, which shares a name with Google’s Web browser, was announced last July. It will be based on the Linux kernel and may become a significant rival to Windows 7 in the Netbook computer space.

Google will release its Chrome operating system for download within a week, according to a report in the blog TechCrunch, which sited an unnamed source.

Launching the OS as soon as possible makes sense, said Rob Enderle, principal analyst at the Enderle Group. “I would expect the Chrome OS will show up shortly because they need the ecosystem ready by the end of 2010,” he told TechNewsWorld.

That ecosystem consists of products from Chrome OS project partners, including Lenovo, Acer, Asus, HP, Toshiba and Qualcomm.

“It appears that Google’s getting ready to finally put some muscle behind its Chrome OS bluster,” Al Hilwa, program director of application development software at IDC, told TechNewsWorld. However, he reckons this is more hype than anything else.

“I get the sense that Google’s trying to leverage the excitement around Windows 7 and get a bit of a ‘me too’ buzz,” Hilwa explained. “Leaking out that it will have some alpha bits for the Chrome OS in a week is really a weak response to Windows 7.”

Google did not respond to requests for comment by press time.

The Chrome OS Project
Google announced plans for the Chrome OS project in July. This caused a degree of confusion in the field, as Google already touted Android as an OS for both smartphones and small computers. The use of the same name for its browser and OS only worked to raise eyebrows even further.

Blame Google’s lack of marketing expertise for doubling up on the Chrome name, Enderle said. “Google has showcased a massive weakness in marketing and branding, and using the same name for both the OS and the browser is a reflection of that,” he pointed out. “Both are largely based on the Chrome browser, but they should have never had the same name.” This mistake will be an expensive one, Enderle predicted.

The Chrome OS is a fast, lightweight operating system that will be open sourced, Google said in announcing the project. It will sit on top of a Linux kernel and will use a new windowing system. The Web will be its application development platform.

Meanwhile, Google is extending the Chrome browser to the Mac OS X platform, and an early developer channel version is now available. The Mac beta will be released in December, according to a blog post by Nick Baum, a Chrome product manager.

Where Are the Partners?
The silence from Google’s Chrome OS project partners such as HP and Acer has been deafening. Why aren’t they rushing to announce netbooks running the Chrome OS?

Perhaps they’re trying to leverage their deals with Microsoft (Nasdaq: MSFT) over Windows 7, IDC’s Hilwa pointed out. “I suspect that OEMs are in constant negotiation with Microsoft about saving an extra penny on a Windows image,” he said.

The advent of Windows 7 may have put pressure on Linux netbooks, which have not been very well received by consumers, Hilwa said. “It could be that Chrome OS will rekindle excitement around a version of Linux in the future, but Google has its work cut out for it,” he explained. “If Google delivers something differentiated and polished, there will be genuine OEM interest in trying a Linux netbook again.”

That doesn’t mean OEMs are turning their backs on the Chrome OS. Lenovo and Acer plan to launch netbooks that will run the Chrome OS, according to the blog Shannan.

Lenovo has already developed a smartbook that runs on the Qualcomm Snapdragon chip, company spokesperson Kristy Fair told TechNewsWorld. The device will be announced at the Consumer Electronic Show, to be held in Las Vegas in January, she said. However, she declined to discuss the operating system that it will used.

OS and Browser Soup
Google has been vigorously stirring the pot in recent weeks, first with the announcement of a new programming language, then with its Chrome OS news.

In September, Google launched Noop, a testable programming language running on the Java Virtual Machine.

Now we have possible leaks about the Chrome OS. Just what is Google trying to achieve?

“The dabbling in languages seems like a collection of side projects at the periphery of what’s important at Google, namely to make money through advertising by keeping eyeballs on its properties,” IDC’s Hilwa said.

That dabbling might be more a symptom of disorientation than get-up-and-go, Enderle contended. “I think they have a huge problem of focus — they’re showcasing an inability to stage products and are starting to compete with themselves heavily,” he explained. “This market likes simplicity, and Google is showing an inability to see that.”

Disk Organization


Disk Organization

Before discussing some of the issues it is necessary to outline briefly some basics about the way disks are organized.


Flash Disk / PenDrive Format in NTFS


Generally all Pen-Drive or Flash Disk run in FAT 32 format System. also Flash Disk Format in FAT format. But if wish to use NTFS Format, of course should be Use. for NTFS format, at first click on the right button, then  go properties / hardware option & select the current Pen Drive or Flash Disk, then from Properties\Policies, select Optimize for Performance, Then Click Ok.

Then the Pen Drive or Flash drive Use The NTFS System.

Note :: before do the format of Flash Disk or Pen drive, must remove Your important data, otherwise data are corrupted or delete.

FAT : File Allocation Table – Old System Of Windows


FAT File System

FAT gets its name from the use of a kind of database called a File Allocation Table that contains an entry for each cluster on the disk. The FAT system has been in use by Microsoft since before DOS 1 (the first version was devised by a teenager named Bill Gates) and has undergone several revisions. There are versions called FAT12, FAT16, and FAT32. The numbers refer to the number of bits used for the cluster entries in the table. More recent PC users may find it hard to believe but in 1987 the FAT system then in use (in DOS 3) was unable to read a hard drive (or more accurately, volume) bigger than 32 MB. (That’s right, 32 megabytes). By the time of DOS 6, the upper limit had been enlarged in several steps to 2 GB but the ever increasing size of hard disks made yet another revision necessary. With Windows 95B, FAT32 was introduced, increasing the upper limit to 2 terabytes (theoretically but not practically). These continual problems with disk size arose from several causes, including the fact that the number of entries in FAT is limited by the finite number of bits used for describing the location of a cluster. For example, FAT16 can hold no more than 2^16 or 65, 526 cluster entries (actually somewhat less). Another factor is that the number of sectors per cluster is also limited.

A further problem with bigger disks is the large amount of wasted space or “slack”. Since there are a fixed number of clusters available, larger disks mean that the cluster size has to be increased in order to fill the available space. However, this results in more and more unutilized disk space since a typical file is rarely close to an even multiple of a cluster size. For example, a FAT32 system uses 16 KB clusters for partition sizes between 16 and 32 GB. A 20 KB file would require two 16 KB clusters actually occupying 32 KB of space. A mere 1 KB file still requires 16 KB of space. A typical large disk might have 30% or even 40% of its space wasted this way. Making smaller partitions alleviates slack but with 200 GB disks now common, and ever-bigger ones on the way, partitioning is no longer a practical solution.

Another problem is file fragmentation. Although a file may require several clusters, the clusters need not be in close physical proximity on the disk. When a file is loaded to the disk the operating system chooses unused clusters wherever it finds them. If many files consist of widely separated parts, the time required to retrieve them for program use inevitably slows the system (hence the need for defragging).

It has to be remembered that the FAT system was first devised when the computer environment was very different from what it is today. Indeed, the PC as we know it did not even exist. FAT was intended for systems with very little RAM and small disks. It required much less in the way of system resources than did the file systems in Unix and other big computer systems and did its job well when systems were small. NTFS and Windows XP are practical for consumer PCs today only because the available resources of RAM and hard drive size have reached levels far exceeding anything imagined when FAT was first put into use.

Actually, the FAT system has been enjoying something of a come-back. Thumb or flash drives have become very common and these are of a size that makes the FAT system useful. The smaller sizes are even formatted in FAT16.


NTFS – Latest, New Generation File System


NTFS

In the early 1990’s Microsoft, recognizing that DOS based Windows was inadequate for the much heavier demands of business and industry, began work on different software designed for much larger systems than the home PC. At first this was a joint effort with IBM, using what became IBM OS/2 & employing a file system named HPFS (High Performance File System). As we all know, the cooperative attempt did not work out and the two companies soon went their own way. Microsoft developed the various Windows NT versions, which then morphed into Windows 2000 and now Windows XP. Each one of these operating systems has its own version of the file system NTFS, which has also undergone evolution.

Going into the details of NTFS architecture would be too overwhelming for this current article so I will limit myself to a few points. NTFS is much more flexible than FAT. Its system areas are almost all files instead of the fixed structures used in FAT. Since files are used, the system areas can be modified, enlarged or moved as is needed. An example of one of the several system files is the Master File Table (MFT). The MFT is a sort of relational database with a variety of information about all the files on the disk. If a file is small (1 KB or less) the MFT may even hold the file itself. For larger files NTFS uses clusters in assigning disk space but in a way different from FAT. The cluster size will not normally exceed 4 KB. A type of individual file compression is built in so that the problems with slack do not arise.

Because it is intended for multi-user environments, NTFS has much more security built in. For example, the XP Professional version (not the Home version) allows permissions and encrypting to be applied to individual files. While much more secure, XP is accordingly much harder to tinker with. That makes trouble-shooting and system tweaking more problematical. It also means that the user has to be very careful when setting up passwords and permissions on a system. Forgetting a password has much more serious consequences than it did in Windows 98.

The MFT & other System files occupy quite a bit of space so NTFS is not intended for small disks. Also the amount of memory required is substantial. These system overhead requirements, which formerly limited the use of Windows NT to larger computers, have largely disappeared as a factor with newer PCs and their much larger amounts of RAM and very large hard drives.

NTFS Give More Benefit  such as :

1.  Give More Security;

2.  Virus Cannot Attack Frequently & Quickly;

3.  Latest XP version  can run smoothly;

4.  Windows  Open More  Firstly;

5.  Windows made by Encrypted file & this Encrypted file can run quickly & better firstly run in NTFS System but in FAT System cannot read Encrypted File,  or this when FAT /FAT32 System used in XP then run slowly & maximum virus can easily attack the file and spread virus in the system.


PC Troubleshooting; Maintenance


A very good start to protecting your desktop PC or Laptop is to apply some common guidelines that can protect the PC and extend its service life. Here are a few general tips for keeping your PC in working order :
  • A desktop PC or laptop should be locate in a room, where is cool & dry place.
  • The desktop PC should have an airflow buffer space all around. It doesn’t need to be more than a few inches wide but make sure that you can allow ample air space around the PC, avoiding draughty & dusty areas.
  • Because the Desktop PC’s cords and cables can be a hazard to you and other people, keep them together and tucked away to protect the cords, the PC, you & others.
  • When a desktop PC is powered up and down frequently, the heating and cooling can stress the motherboard and other electronics, leading to intermittent problems from degradation and eventual catastrophic failures. Avoid powering the system on and off frequently.
  • Most new PCs have many energy-saving features built into the Basic Input/Output System (BIOS), chipset, and operating system, such as suspending the hard disk and monitor. These features not only save electricity, but they also extend the life of the PC and its components.
  • Always the desktop PC or Laptop will connect to the alternating current (AC) power source through a surge suppressor or an Uninterrupted Power Supply (UPS). This UPS  always will protect the PC from possible damage caused by electrical spikes, surge, blackouts and brownouts.
  • Always wear an antistatic wrist or ankle strap when working inside the PC’s case to avoid possible damage from electrostatic discharge (ESD).
  • Always before shut down the operating system, must close any open applications and power off, unplug the cable of Desktop PC from its power source.
  • Never place a PC & especially it’s monitor or stereo speakers, near any strongly magnetized objects, which can distort the image and sound produce by the monitor or speakers and possibly eventually damage disk storage devices as well.
  • Always shut down the desktop PC, before connecting or disconnecting a serial, parallel, or video device. Universal Serial Bus (USB) and fire wire devices can be hot plugged and are a better choice for devices that need to be removed and replaced often.
  • Always try to use better, update & registered software but if you use free software, then must you’ll confirm that the software publishers is renowned or remarkable software company.
Security System ::
  • Always open your Windows Firewall, if you feel unsecured, you can use extra brand best firewall such as comodo firewall, iolo firewall, kaspersky security suite. But now, windows firewall is best and give better performance.
  • Always try to use the better & best Anti-virus Software / Security Suite such as Microsoft Essential, Kaspersky Internet Security, Bitdefender Security Suite. If you unable to buy this security suite, you can use the best free Security Suite; Microsoft Essential, Bitdefender Free edition, AVG, Forticlient Endpoint security Suite.
  • Always back up important data and software in a CD, DVD or Blue Ray Disk. But now it is best to do backup all data in Internet mail storage.
