Upgrading RAM on your Computer

RAM is an acronym for Random Access Memory. RAM is an important part of any computer system. RAM is memory to hold frequently used bits of data for the computer to access in an efficient manner. Accessing RAM as opposed to the hard disk is a lot easier and quicker for a computer.
RAM is essential for several different applications, but more so for some than others. For example encoding video would take up a large amount of RAM as it is RAM intensive. Database applications also use up a lot of RAM due to the amount of data involved. Surfing the web and using word or powerpoint for example would not use much RAM at all. The question you need to ask is do you need the upgraded RAM. If you don t then save your money. If you do please read on.
There are several options to choose from when upgrading RAM. The first is the size of RAM you want to purchase. They come in 256mb, 512mb, 1gig and 2gig varieties. Just as a quick reference 1gig of RAM will be enough for most things you want to do, 2gig might be overkill.
Once you pick the size of the RAM you want you have to choose the type of RAM. There are two main types of RAM. DDR and DDR2. What you have to take into account when buying the RAM is which type your motherboard will support. Most new Intel motherboards will take DDR2 as this is the latest technology. At present AMD boards are not compatible with DDR2 so if you have an AMD board then you will have to buy DDR RAM.
Once you buy the RAM then you have to install it. Installing RAM is really quite simple. Firstly you need to remove the case in order to be able to get to the motherboard. Once this is done you simple need to put the RAM into one of the free slots on your motherboard. Something to take note of would be the particular slot you put the RAM in. Some motherboards can be particularly fussy so read the user manual of your motherboard before upgrading the RAM.
There you have it, improving the speed of your computer by upgrading the RAM is very simple and can be very effective.

What is Virtualization?

There are a lot of noise going on around virtualization.
What is virtualization, and what advantages they provide?
In this article we look at technology to
how it can provide greater flexibility and cost
effectiveness for IT professionals and software developers.

Virtualization technology allows multiple virtual machines
to run on a host computer. These virtual machines can
run different operating systems such as Windows, Linux and
UNIX. Each virtual machine has its own set of virtual
hardware resources (such as CPU, memory, hard disk, etc.)
allowing operating system to run as if it was installed
on physical machine.

The benefits of virtualization technology are far-reaching.
Many organizations shifted to a virtual machine
solution consolidate several servers, working side by
side on one physical computer. The consolidation of servers
allows IT professionals to fully utilize the resources server,
while isolation of virtual machines and allowing them to run
different operating systems and applications. Software
developers use technology virtual machine for rapid
test applications on different operating systems, without the hassle
the on setting up multiple physical machines for
testing or taking the risk of causing problems by testing in
a working environment.

You can read about the virtualization software quite a lot of any
platform. Once the software is installed simply
create virtual machine instances. Virtual machines
a simply a collection of files located on the machine. You
your configure a virtual machine settings on the host computer, install
the operating system and you& 39;re ready to go. This is a very practical use
common master image virtual machine.
This master image can be fully configured machine, with
the operating system and all the necessary applications
installed. You will be able to rapidly deploy virtual machines at
copying master image for a few Virtualization hosts
provide zero downtime and 100% availability server.

There a series of virtualization products available.
VMWare, which is probably the most popular, recently
announced, that it will release of a free version of its product
GSX Server. This will allow any organization, the host
virtual machines on any Windows or Linux hosts. Other
Virtualization Microsoft products include a virtual server and the company SWsoft Virtuozzo, just to name a few.

Computer Data Backups: Test Now or Cry Later

If you& 39;re like most small business owners, backup data your computer is one of those things that you rarely attention. Computer data is a kind of backup, such as cleaning your teeth and eating low-fat, high-fiber foods ... everyone knows what is supposed to play ... but how much do these things really religious?!?
unfortunately when it comes to your computer data backup, however, can be very dangerous complacency. Of course, always a good idea to have the local computer service company that you can rely on for advice on selecting and maintaining your computer data backups. But, unless you are prepared to support a full-time computer person on the company payroll, and it was really important to get a basic understanding of key issues with computer data assistants.
so Here& 39;s a compilation of tips on some really crucial computer data assistants I& 39;ve put together, after almost 15 years to help small businesses in protecting valuable files and computer data.
test your computer data backup regularly and monitor log files.
to to be effective, and automated computer data assistants must be high to ensure that jobs that open consistently and correctly, but your computer system backup data and there is also a need to witness to the extent hard to make sure they still operate reliably.
unfortunately, and control Data backup computer system in general is not a priority Needless to something so wrong. Then before it is too late . Such as the article title says: " test now or later in tears! & Quot;
people have a strong tendency with the computer system backup and data prepared and Miss. Automation clearly many benefits, but the hands completely - from an approach could be very serious if no one is supervising your computer process backup data.
test and then test again: it is very important with the computer systems and backup data
with any newly installed computer system backup data, do not assume the right to everything is working correctly out of the box. More importantly, do not take for granted that your backup system will continue to work indefinitely. You need periodically to restore some folders and files from your backup media to make sure that your computer system backup data is still operating.
if computers your backup data routinely to include verification of the backup operation with each post, the test sample restore function monthly should be sufficient. However, if you had a very low tolerance for risk, you may wish to emulate the model restoration of one per week.
the danger of moving parts, open design with a computer backup systems
why Do you need to take these precautions if you buy reliable, business-class computer data backup system to begin with? And usually paid a tape or other backup devices is one of the few elements in the PC or service that are still moving parts.
as a result, which is more prone to mechanical failure of unemployment. In addition, because the backup system generally open, unlike the sealed design of the hard drive because they are easy inside of Data backup computer system is an important tool to attract construction dust in a relatively short period of time.
sample restore jobs and clean up the tape heads of computer systems and data backup tape
testing sample to restore function is also a great time to clean the heads of backup drive if your backup and requires a system of this type of maintenance.
restoring few hundred megabytes (MB) of data to scratch and guide the management of Cape cleaning tape should take no more than 15 to 30 minutes.
when re-test the operation and function of data recovery always an alternate way volume server, so as not to disrupt the use of any of the volumes involved.
building computer system backup and restore procedures reference
in times of crisis, the most crucial issue becomes how quickly you can obtain data on the return of your system, a wrecked. Thus, as you build your computer system for data backup, be sure to document your test procedures to the lists useful.
this documents can be significant cross-training and also crucial to avoid panic during emergencies. It is certain that you have hard copy of these documents coming to your system and storage off-site with the media your backup.
watching entry in the files of your computer system
in backup data, in addition to reboot and test functions, we must lose your computer backup data files record the day. When the backup to install the first system, take time to get to know how we log files When everything works. In this way, if something goes inclination, you can be better prepared to determine the exact nature of the problem immediately.
as network operating system (N) and backup software suites have become more complex, it is now possible to monitor the backup system log files remotely and more active. In most cases, the backup system log files are just plain text (. Text (files.
many third party, tools and utilities, as well as those listed backoffice with Microsoft Small Business Server (Trial) and Microsoft server backoffice, can be automatically e-mail or fax a backup record Preconfigured file system at the time.
automatically remote monitoring and tape backup log files
many computer consultants for its small business customers log files automatically by e-mail daily, so the consultants can be more proactive to see potential problems with the computer system backup data.
however , I do not think that this proactive monitoring limited to professional consultants. If the company of one or more branch offices are from a central location, you can also use a similar method to monitor the backup system of health in remote locations.
for greater flexibility, You can create e-mail alias so that the computer system backup data log file automatically sends you, the second in command and perhaps an outside consultant computer - so you stay in each cycle. Well, and in this way, monitoring continues even when you are away from the office or On leave.
the crux of the matter
if small business of your depends greatly on computer systems, backing up your data ... is not optional and it is not something to be brushed aside an offer.
use computer backup data in articles tips to help you to Become more aware of it - small business owner. Remember that when it comes to computer data assistants, " test now or later in tears & quot;. Option for you.
