Operational System Differences ‰ÛÒ Linux Windows Chrome Mac OS X
No matter whether we have used or not, we must have heard these four operational systems, Linux, Windows, Chrome and Mac OS X. Maybe there are many opinions or deep understanding about them. So in this passage, I just introduce every operating system simply and make a summarization about differences between operating systems. And express my opinion about how to choose one suitable operational system for oneself.
1st OS: The older operational system Ð Linux
Linux is a free operational system with all of functions included in UNIX. Stable performances, high
efficiency and flexibility make it become popular for almost of computer hobbyist to learn, research, and modify computer operating system kernel. And this is why computer users like to use Linux.
But to be more, Linux is just the kernel. It is still difficult for common computer user to install and run it on computer. Because Linux traditional user interface is command interface based on text. And why it is different to computer hobbyist? There are mainly two reasons.
1. Linux is like free software.
Anyone doesnÕt need to pay for it to get its original code and computer user could modify it according to their purpose. Free use and transfer it freely.
2. Linux includes all of functions of UNIX.
So for people who want to learn UNIX or use UNIX, Linux is the best platform.
Therefore, for computer hobbyist, there are still advantages in Linux.
- Openness.
- Multi-user and multi-task.
- Friendly user interface.
- Device independence.
- Kinds of Network function.
- Safe system security.
- Good portability.
Now see the differences between Linux and Windows/OS X:
- In development history, Linux is developed from a relatively mature operational system. And Windows is designed newly and independently.
- In cost, Linux is free. And Windows and OS X have to be paid for.
- In usability, Windows and OS X are friendlier than Linux for common computer users.
2nd OS: Google special operational system Ð Chrome OS
Chrome OS is open operational system based on Linux, designed for netbook. Actually, Chrome OS
is Web operating system. Most of data and files are dealt with on Internet. So how is Chrome OS?
- There is no ÒUserÓ in Chrome OS. Google account will be used to login into Chrome OS instead of ÒUserÓ.
- Network is needed when you access Chrome OS. Not like Windows, login Windows with user and do work on Windows computer without network are available.
- Chrome OS looks like a Chrome browser. No data are saved on local computer. All of them are stored in Cloud. And all of system applications are Web applications.
- Because of lack of local file system and desktop, security of Chrome OS is no match for Windows.
- Just about few seconds are needed to boot Chrome OS, but about a minute to boot Windows.
- Less demand in PC computer power if you use Chrome OS.
Even though there are so many advantages in Chrome OS, some questions are still asked usually. For example, Chrome OS couldnÕt be used when no network is available? Is Chrome OS free? PC users only install Chrome OS? To respond to these problems, Google also says, they will make progress in Wifi, data encryption, access Google Docs offline. But these would take time to achieve.
So if you want to experience how Chrome OS works, install Chrome browser to experience is a good choice.
3rd OS: Most humanized and comfortable operational system - Mac OS X
Mac OS X is designed especially for Mac series products. Based on UNIX, it seems to be simple and full of innovation. Mac OS X is friendly-use and it can be handled once people begin to try to use it. So now see why we choose Mac OS X?
- System interface is beautiful than any other operational systems.
- Easy-of-use. Anyone could learn to use Mac OS X instantly. And it is no need to install other third-party software.
- More safe. Because of no need of downloading third-party software, netbook is not so dangerous.
- More stable.
Generally, it is not necessary to adjust system programs.
But why it is said Mac OS X is not suitable for general computer user?
- Mac OS X is special operating system only provided by Apple. It is hard to find one and install it.
- Lots of software available for other operational system is not available for OS X, such as games software. So its compatibility is not so good for general computer user.
So we can see the differences between Mac OS X and Windows. Try to understand why Windows is more suitable for common computer users and Mac OS X is not. And there is no doubt that Mac OS X is good operating system actually.
- Mac OS X runs faster than Windows.
- Mac OS X is more stable than Windows.
- Windows is better than OS X in compatibility.
- Mac OS X is hard to be poisoned than Windows because its fewer users and less chances to get touch with third-party software.
- It is easier to realize double system in Windows computer than Mac.
- Mac OS X is more humanized than Windows. But people who use Windows could become computer experts, but not for Mac users.
4th OS: Common operational system ÐWindows
Windows is one operational system which is used widely both for persons or corporations. From the above introduction, we could see, its easy-of-use and compatibility are two main reasons. Now letÕs see the advantages of Windows:
1. Intuitive and efficient object-oriented graphical user interfaceWindows user interface is object-oriented. It works with way ÒChoose object Ð Operate objectÓ. For example, we choose document first with keyboard, and then choose ÒOpenÓ button in right-click menu. It imitates behaviors in real life, so it is easy to understand, learn and use.
2. Unified and friendly user interface
Most of Windows programs meet standard of Common User Access. All of these programs have the similar appearance, including window, menu and toolbar. As long as user handles one of them, there would be no problem to use others.
3. Rich and device-independent graphics operations
Windows GDI provides rich graphics operations functions. So we can draw different kinds of graphics and different kinds of output devices are supported.
4. Multi-task
Windows permits user to run different kinds of tasks in the same time. Every program would run in window. Computer user could move these windows to change program running in different time.

Start the "Terminal."
á Enter this command: resetpassword
á A new window appears allowing you to change the administrator password.
á When you restart the Mac, you can use the new password.
Now look at the main window that appears when you start up your Mac in "Recovery HD":
"Recovery HD" allows you to run a restore from backup "Time Machine" to launch "Safari" to surf and have particular online help, launch "Disk Utility" to repair minor injuries your OS X system and also boot / partition hard drives connected to the Mac, and perform a re-installation of OS X if necessary.
So finally, you will tell me if your Mac YOSEMITE faces some problems, well instead of starting as in the past on the installation DVD, youll be able to boot to that partition to start small basic repairs via "Disk Utility". Certainly it is possible, but since you have a clone having many more powerful maintenance tools, Im sure you already Demarrias more on the DVD to perform this type of basic maintenance operation ... then you will not start on that partition "Recovery HD", right?
And to re-install the system in case of need? In the past, yes, actually the best way to conduct a clean install of your OS X system was started on the installation DVD and do so to the re-installation of OS X. But now I urge you to do not go through "Recovery HD" to re-install OS X on your Mac.
Indeed, although it is of course possible to re-install OS X via the "Re-install OS X" function offered by "Recovery HD" This solution is not, in my opinion, not the best nor the most practical. If you have a clone, then preferably use the clone to make an OS X re-installation.
By default this partition "Recovery HD" is installed on the same hard drive where you installed OS X YOSEMITE. But what happens there if unfortunately your hard drive were to let go? Without clone bootable USB drive without installation YOSEMITE (crafted by you), it will NOT POSSIBLE not boot from this partition "Recovery HDÓ!!! So what?
Apple offers to download HERE a "Disk Recovery Wizard". This wizard letÕs just clone the partition "Recovery HD" to another hard disk (external drive) or even a USB drive. But be careful, in this case, this key will IN NO EVENT key USB bootable installation YOSEMITE, but it will just be a clone of the partition "Recovery HD" you already have on your hard drive. You can use this partition clone "Recovery HD" if you cannot use the partition "Recovery HD" located on your hard drive.
Its a little spare tire of the spare wheel.
NB: It is necessary to make the partition clone "Recovery HD" before the partition "Recovery HD" is no longer operational, of course.
Important note about the Mac market after the release of LION 10.7
Macs sold since the release of LION and therefore come with LION MOUNTAIN LION, MAVERICKS or YOSEMITE now installed on the machine, also have a function "OS X Internet Recovery" that allows you, in case of failure your hard drive and / or hard disk change, start your Mac directly from APPLE servers to process resettlement OS X. This feature is not available for Macs before the release of LION and therefore that had been purchased with a previous version of the system (or SNOW LEOPARD LEOPARD).
"OS X Internet Recovery" checks your machine, including its serial number (to verify that your Mac is allowed), and then automatically downloads and launches an image of the hard drive recovery.
To do this, you must have an Internet connection because you will have to download more than 5 GB of data necessary for the relocation YOSEMITE!!
More on "Internet Recovery OS X" HERE.
Why make it simple when you can make it complicated? Some will no doubt think that this system is practical and modern because it avoids having to annoy to re-install OS X, but I honestly think that APPLE would be much better to continue to offer the sale of bootable USB keys OS X and especially to slide one in every Mac sold in cartons YOSEMITE, rather than forcing new buyers to go through this function "OS X Internet Recovery" really not practical. Everyone does not necessarily have a high speed Internet connection, and how to re-install OS X and its MacBook Air or MacBook Pro when you are in a place without an Internet connection?
Indeed, the new Mac buyers have no choice but to go through Apples servers to re-install OS X if something goes wrong with their hard drive, they have neither USB Bootable of installation or installer (downloaded from the Mac App Store) they could use from a clone.
In short, after reading the above, it is better to take all possible precautions to deal with any difficult situation. I do know strongly advise you to urgently provided a clone of your YOSEMITE installer and / or you make a bootable USB installation YOSEMITE key.
Indeed, the new Mac buyers have no choice but to go through Apples servers to re-install OS X, if something goes wrong with their hard drive, they have neither Bootable USB key to installation or installer (downloaded from the Mac App Store) they could use from a clone.
