Cloud computing is committed to handing over all hardware and software resources and computing work to the remote "cloud. Simple, such as Google Docs, mature, such as Amazon AWS. For example, in AWS EC2, You can construct a virtual machine + software and hardware configuration as needed to do the work you need. You only need to do two things. One is to open the console in a browser to manage instances, and the other is to connect to a remote server through a local RDC or VNC.
In this way, clien
Go to the Ubuntu official website to see several versions that can be downloaded: alternate (Text installation), desktop9 (desktop), netbook (netbook), and server (server ).
Reasons for using server:
32-bit systems can use 4 GB memory or above, up to 64 GB. The premise is that the motherboard supports

If the required software is not pre-installed in the Ubuntu system, you can also find it in the Ubuntu Software Center. Installing a new software in Windows is basically a very difficult task. You may spend a lot of time searching in Google, and you may have to pay for it. However, Ubuntu's software center contains thousands of open-source software, where users can find their desired free s

After the script is run, the following content is output:

We have introduced how to run the MeeGo SDK on mainstream Linux operating systems. In China, developers generally use Windows operating systems, so we need to talk about how to run the MeeGo SDK on Windows.System Configuration Requirements
1. Currently, MeeGo SDK only supports Windows Xp and Windows 7 operating systems. The MeeGo SDK is not guaranteed to work in Vista and is not supported.
2. The simulator can only work in 32-bit windows. If you are using a 64-bit system, sorry, you will not be
The last beta version (Beta2) of Ubuntu10.04 was scheduled to be officially released on July 22, April 8. With this release, tens of millions of Ubuntu users around the world are eager to look forward to it. It can be called a "coming soon. Why? At 03:32 this morning, I first found the official release of Ubuntu10.04 (LTS) Beta2 on a foreign website, and I was immediately excited. This release is like launching an "exclusive gun". It is very powerful and has released Ubun in total.

The disk array (redundant Arrays of inexpensive disks,raid) has the meaning of "inexpensive and redundant disk arrays". the principle is to use array method to do disk group, with the design of data distributed arrangement, improve the security of data. The disk array is made up of many inexpensive, small, stable, slow disks, combined into a large disk group, a
RAID: Redundant array of independent disks.
In the early days it was called the redundant Arrays of inexpensive disks, a "cheap Redundant array of disks"; it turned out that the inexpensive effect of such a device was really high. Therefore, change ' inexpensive ' to ' independent ', what we now call "independent redundant disk array".
