I bought my 1st computer system in 1985. I saved up to
obtain this laptop. I study a book on DOS 2.1 a few years earlier. I’d
understand about computer systems. The IBM Pc Junior price me $635.00. At this
time, personnel in my business worked at terminals connected to a mainframe pc
in a central location. There were two IBM AT kind computer systems in our
division. A single was in fact utilized. An engineer told me I wasted my cash
on the laptop; we would never use personal computer systems at function.
The applications on my personal computer in 1985 are gone
now. Applications like, lotus, dBase, and Word Star. Now, I’ve in my residence,
a Dell desktop pc, an IMAC, a dell portable, and an IPAD2. I use each personal
computer for my Emily and Jim web web page, my first line manager weblog, and
my Beta Theta Pi chapter web page. I use Dreamweaver and Frontpage to construct
and add to my net pages. I’ve U-tube and Face book accounts.
These days, at perform personnel are helpful for the reason
that we have a computer on our desk. The pc expands the capabilities of each
employee. That is certainly, each employee with pc knowledge. We’ve got no
mainframe but we have hundreds of file servers. It is a planet never ever
imagined by that engineer in 1985.
Over the years I came to know that most laptop or computer
system logic will be the related. The … Read the rest >>>>
Virtualization is not a new technology. Remember
your good old desktop computer? When it first came home, and the engineer set
it up for you, you could see two drives in it ‘C’ and ‘D’. All we knew was that
C drive stored important system files while the D drive could store our games!
The interesting thing was that while we could use two drives, the system only
had one hard disk drive in it which was partitioned virtually allowing us the
benefit of two drives with several independent features. Over the last decade,
tech experts have leveraged virtualization to offer virtual servers which can
be used for various things. Today, we are going to talk about two types of
virtualizations – OpenVZ and KVM.
OpenVZ and KVM virtualizations
Kernel-based Virtual Machine or KVM is a technology focused on the kernel of the Linux machine. Using KVM, you can convert the kernel into a hypervisor and create virtual servers. It operates only on the Linux operating system. Since 2007, KVM has been bundled with the Linux Operating System and you can install it along with the kernel. KVM is true virtualization where the VPS functions as its own server.
the other hand, OpenVZ is a virtualization technology which works on the OS
level on Linux. Hence, different containers on the machine work in an isolated
manner but share the same operating system. Also, each container works like an
independent server, has root access, IP addresses, configuration files, etc.
