Enterprise version of RedHat, shortened to RHEL. The following versions are available:

One, Red Hat Enterprise Linux AS

A typical Red Hat enterprise Linux AS application environment is as follows:

Databases and database application software.

web and middleware.

crm, erp，scm

Second, Red Hat Enterprise Linux ES Red Hat Enterprise Linux ES (Entry Server).

Provides the Intel x86 market with a server operating system from the enterprise portal to enterprise mid-tier applications. It supports systems with 1-2 CPUs and less than 8GB of RAM. It offers the same performance as Red Hat Enterprise Linux AS, except that it supports smaller systems and lower costs.

Third, Red Hat Enterprise LinuxWS

Red Hat Enterprise Linux WS (Workstation) is a desktop client partner for Red Hat Enterprise Linux AS and ES. Red Hat Enterprise Late Hidden Slag Linux WS supports Intel and AMD systems with 1-2 CPUs, making it the best environment for desktop applications. It contains a variety of commonly used desktop applications (Office tools, mail, instant messaging, browsers, etc.) and can run a variety of client-server configuration tools, software development tools, and various applications (such as EDA and Oil Gas applications).

Red Hat's enterprise Linux WS and server products are compiled from the same source**, but they do not provide network services (such as DNS and DHCP) and are only suitable for client applications.

There is no difference between the two, it is the same originally. The full name is Redhat Enterprise Linux as 4 Update 4. Hehe.

Redhat Linux was an early product of Red Hat, which later diverged into Personal Desktop FC and Enterprise Editions. The Enterprise Edition is divided into CentOS and RHEL, the latter is orthodox and the former is the Community Edition.

The former is the desktop version ...... long since discontinuedIt's old.

The latter is the enterprise version and should be the most recent.

If your CPU does not support physical address extensions or the BIOS disables physical address extensions, the solution is either to turn on the PAE disabled in the BIOS, or to change to a kernel that does not have a built-in PAE.

What software are you installing?

The meaning seems to be that the kernel is not synchronized and cannot execute a CPU with less PAE on the kernel!

Agree to stablish - level fourteen.

Your CPU does not support PAE (Physical Address Extension), so you can't use the PAE kernel, you can reinstall a kernel that doesn't contain PAE.

It may be in your software installation disk, and then you can install it.

It doesn't seem to work, I mean QQ, you have to use the next one. And the function is similar to that under Windows, which is very easy to use and easy to install.

rpm format.

You may be talking about gaim, which has now been renamed to pidgin, and officially supports QQ, but the effect is average, and it is not as easy to use as EVA.

If you charge now, your next centos will be the same as Redhat.

There are many companies, but it's a pity that I can't give it to you.
