Buying the Perfect Computer – The FIRST Time

Written by Dan Preston


So you’ve finally decided it’s time for a change. No matter what advice you follow that old work horse of a desktop computer you have has outlived its usefulness with slow loading applications and

a continuous rise in operation noise. Searching for that Perfect Computer can be about as much fun as purchasing a new car and about as frustrating also when sorting throughrepparttar various brands while trying to decide which “bells and whistles” best fit your needs. Besides all that trying to return something that is so large can be both inconvenient and very difficult to do. So makingrepparttar 107746 right decisionrepparttar 107747 FIRST time isrepparttar 107748 wise path of choice.

For starters you’ll need to decide what you want to do with your computer. Are you intorepparttar 107749 video game scene or are you someone who likes to just surfrepparttar 107750 internet and occasionally do some book keeping with simple word processing software?

If you’re into video games you’re going to want a machine that can handlerepparttar 107751 high level of graphics and superior sound quality. Onrepparttar 107752 other hand if you’re not into all that high adrenalin stuff can probably get by with a less expensive system. Although, if you want to stay onrepparttar 107753 safe side I would recommend going with something more “high-end” so you don’t have to spend another large chunk of change to upgraderepparttar 107754 system you just bought.

There are two basic routes you can take when purchasing a new computer. 1) Purchase a “Brand Name” Computer 2) Purchase a “Clone” Computer

A “BRAND-NAME” computer is one that is manufactured by a company that is recognizable by name.

Some Advantages/Disadvantages of “Brand-Name” computers include:

Advantages-

Customer Support- If you are experiencing problems with your computer you will haverepparttar 107755 option to contact a representative ofrepparttar 107756 company that you purchasedrepparttar 107757 PC from to get help in solving your problem.

Customer support is probablyrepparttar 107758 best reason to buy a brand-name computer.

Warranty- Having a warranty is always nice since it acts as a type of security blanket for you.

In case a part on your computer should fail you should be able to getrepparttar 107759 item fixed at no charge just as long asrepparttar 107760 warranty has not expired.

Read and understand a company’s warranty policy BEFORE you purchase a computer from them.

This way you’ll have a good understanding ofrepparttar 107761 procedures to follow in case a problem should arise.

Pre-installed Software- Many companies will include software packages that are all set up and ready to go for you on your computer.

Although, a disadvantage of buying a brand-name computer with software pre-installed is that you usually end up with more than fits your needs and usually just results withrepparttar 107762 wasting of space on your storage device.

Additional Support- Most brand-name computer companies are also able to provide you with web sites that may provide you with current software updates, user manuals, or basic troubleshooting help.

Disadvantages-

The use of Proprietary parts-repparttar 107763 term Proprietary refers to products that are unique to an individual company and that company only.

So if a part was to malfunction on your computer after warranty and you needed to replace it you could not just go to your local computer store and purchase any old part even if it was intended forrepparttar 107764 same function asrepparttar 107765 item that failed.

You would be forced to buyrepparttar 107766 exact same item that came out ofrepparttar 107767 computer or elserepparttar 107768 computer would more than likely cease to function correctly.

Having to buy proprietary parts usually involvesrepparttar 107769 need to place an order which means you’ll have to wait forrepparttar 107770 part to arrive or you’ll have to send your computer into repparttar 107771 company or an authorized dealer of that company for repairs.

People with a home based business would probably not be too happy with that situation at all.

Integrated/On-board parts- Inrepparttar 107772 computer world when you hearrepparttar 107773 word integrated or on-board it means that a particular part such asrepparttar 107774 modem or sound port where you plug in your speakers, is built-in or part ofrepparttar 107775 computer main board (Also known asrepparttar 107776 Motherboard).

This means that if any of these items should fail, you can’t just remove them fromrepparttar 107777 computer and replace them with a new part. They are usually soldered directly to repparttar 107778 main board and are stuck there.

Linux Runlevels

Written by Vinu Thomas


Linux systems today generally use eight runlevels. Runlevels define what services or processes should be running onrepparttar system. The init process can runrepparttar 107745 system in one of eight runlevels. The system runs only one ofrepparttar 107746 eight runlevels at a time. The main runlevels are from 0 – 6. Here's what each runlevel is for

Runlevel 0: Halt System - To shutdownrepparttar 107747 system Runlevel 1: Single user mode Runlevel 2: Basic multi user mode without NFS Runlevel 3: Full multi user mode (text based) Runlevel 4: unused Runlevel 5: Multi user mode with Graphical User Interface Runlevel 6: Reboot System

Runlevels 1 and 2 are generally used for debugging purposed only, and are not used during normal operations. Most desktop linux distributions boot into runlevel 5, which starts uprepparttar 107748 Graphical Login Prompt. This allowsrepparttar 107749 user to userepparttar 107750 system with X-Windows server enabled. Most servers boot into runlevel 3, which startsrepparttar 107751 text based login prompt.

Linux runlevels can be changed onrepparttar 107752 fly usingrepparttar 107753 init tool. If you want to switch from text based operations torepparttar 107754 Graphical Interface, you just have to type in 'telinit 5' inrepparttar 107755 root prompt. This will bring uprepparttar 107756 Graphical Interface in your system.
