Building A Computer – Picking the Components

Building A Computer – Picking the Components

Building A Computer – Picking Components
Picking the parts for your computer is one of the most important things in building a computer, because you cant assemble a computer without the parts! Picking parts for computers has become much easier than before, because things have been standardized, however, you need to make sure everything will fit. The first thing to think about when choosing the components for your computer is what you are going to be using it for. If you are creating a computer for just checking your eMail and using word, you are going to need much diffrent parts than a computer that you are going to be using for gaming.
CPU
The first thing you should pick out about your computer is what CPU you are going to use, because it determines what motherboard you are going to get, which determines what other components you get. There are two main CPU manufactruers, Intel and AMD. Both have their Pros and Cons, but they are pretty similar. I would suggest using AMD, because they give you a little more bang for the buck.
Here is a brief overview of the diffrent Intel and AMD CPUs:
Budget: AMD: Sempron
Intel: Celeron D
Midrange: AMD: Athlon 64
Intel: Pentium 4
High End: AMD: Athlon64 X2
Intel: Pentium D
If you are spending below 0, I would suggest a budget proccesor, Between 0 and 00, midrange and 00 and above I would suggest a high end proccessor.
Motherboard
Choosing the right motherboard is vital to building your computer. First, make sure you find a motherboard that has the right socket type for your CPU. Then, check the diffrent features of the motherboards you are looking at. If you arent going to buy a video or sound card, make sure your motherboard has onboard video and/or sound. Other things to check for on your motherboard are the hard drive interface, graphics card interface, expansion slots, the memory size and speed. Also, check for the chipset. There are too many to talk about, but generally Intel and nVidia chipsets are better than the other ones. Now that you picked out your motherboard, you know what to look for in your other components.
RAM
Getting the right speed and amount of RAM is vital to the speed and stability of your system. If you are running XP, you will probably need at least 256 or 512Mb of RAM. If you are going to be doing anything memory intensive, gaming, rendering or just want a faster computer, you should get 1Gb. Make sure your motherboard has enough DIMMs and the right type of DIMMs for your RAM. Also, be sure to check the speed and CAS Latency.
Hard Drive
Now its time to pick your hard drive. There are few variables in picking a hard drive. The first, and most important is size, 120Gb is usually enough for most people unless, you are going to be storing alot of pictures and video. Also, make sure you get an HD with the right interace that fits your motherboard. Almost all motherboards have IDE, but some have SATA (Serial ATA) Which is a much faster hard drive interface and uses a thinner cable which helps with airflow in your case. There is even SATAII now, which is twice as fast. Also look at speed, almost all desktop HDs are 7200RPM and Cache, most are 8Mb, dont buy a HD below those standards. If you want to spend some money, you can get 2 HDs and run them in RAID which increases performance.
Video Cards
If you are going to be doing any gaming, be sure to buy a video card, if youre not, onboard video is fine. The first thing to check for is the interface, most are AGP or PCI-E. I personally like nVidia cards better. If you are going to be doing graphic intensive games, I would suggest at least a 6600. If you have alot to spend, go with a 7800.
Optical/Floppy drives
Another thing you are going to is a CD drive, most are IDE. Get a DVD Burner if you are going to use it. Also, you should get a floppy drive, they are only ish and you might need it to install drivers when building your computer.
Case and Power Supply
Make sure you have a sufficient power supply!! If you have a high end computer, you should get a 450W PSU. Otherwise, 350W should be fine for most people. Most cases are ATX, but make sure it is the same type as your motherboard (ATX, MicroATX, BTX, etc…).
Be sure to make sure all your components are compatible!

Dangers Of Illegal Computer Disposal

Dangers Of Illegal Computer Disposal

If your computer broke tomorrow and it was beyond repair, what would you do with it? Well chances are that after slamming it against the wall in a fit of rage, you’re going to throw it in the trashcan in your garage. Alongside all the other non-recyclable trash your household created this week, the trash men will come pick it up, condense it in their truck, and dump it into a huge pile of waste. The huge pile of waste will be compacted even more, and then sent out to some island where all the huge piles of your garbage go. Sounds simple, right?

Sure, it’s simple enough; until a bird lands on your crunched piece of laptop and dies from exposure to the acid that leaked out of the battery. Gasp! “Alright,” you say to yourself, “I’ll take the battery out and burn it in my backyard instead of throwing it in the trash.” Well unless you’d like an explosion in your backyard, then no, you should NOT burn any old battery solely because you know is it wrong to throw it in the trash.

So what exactly do you do with this battery? How about all the other parts of the computer that still function? After you consider all of the minute details that go into making a computer work, and you realize that your computer might be broken beyond repair but that the tiny pieces could function perfectly in someone else’s computer, it seems like a big waste to be disposing of the entire thing with one careless toss into the garbage. Not only would you be polluting the environment, adding to the amount of waste your family creates, and putting innocent animals at danger with the improper disposal of your computer, but you would also be wasting hundreds of dollars worth of useful items in a computer that can probably be refurbished anyways.

Aside from the battery leaking acid in a waste heap, other environmental concerns are with toner or ink from printers, glass pieces from tiny light bulbs, and other wires and metal pieces tangled inside every computer. Luckily, there are companies that deal with computer disposal or refurbishing to make your job a lot easier. If you feel the need to bash your computer against the wall in a fit of rage, simply wrap it up and send it to a computer disposal company who will, oftentimes for free, properly dispose of your computer. If your computer stops working or you simply care to invest in an updated version, then there are companies who you can send it to who will pay you for the parts that are still useable and will refurbish the computer so they can re-sell it or donate it to a low-income family or agency once it works again.

One might think, “Well, I know of a charity that could really use my old computer. I will donate it on my own”. Not so fast, buddy. Donating an older computer to an organization that you think could really use it doesn’t always work out so well. In many instances, the computer will cease to work after a couple of months, and the organization might have to spend more money to repair it. It is poor etiquette to donate something when you are not quite sure of its value. If you’d rather not give cash, some businesses will take your old computer and send the cash value of its remaining parts to an organization of your choice.

The bottom line is that there are many different things you can and should do with a computer that you no longer want as your own. For the same reasons that you taught your children how to recycle, that you turn off the lights when you leave a room, and because you try to take only as much food as you are prepared to eat at a buffet table, you should dispose of or recycle your PC properly.

The Best And Simplest Computer Virus Protection

The Best And Simplest Computer Virus Protection

Many computer users live in fear of computer viruses. It is true that computer viruses can do a lot of damage that most likely could have been easily prevented – that is if they had a working up to date virus program.

First of all be reassured. Even if your computer is “wiped clean” or “wiped out” you may not be in the doghouse so to speak. If you use the computer mainly for browsing on the internet, then it is only a matter of a reinstall of windows to get you on the web again. Your computer is only a device to access the internet. It is as if you get a new phone to plug into the wall or a new TV to watch the channels that were there that were and are still there.

Your email most likely is safe as well. If you use a web based mail program like hotmail or yahoo to access your email – then your email is most likely still sitting on that company’s server in California, Bombay India or somewhere else in the world. If Microsoft goes bust, your lost email will be the least of your problems in today’s world. If you use a mail reader client like Microsoft Outlook or Outlook Express, then at the worst your new email is sitting safely at that computer mail server computer.

Next it can be can be said that we have gotten off easy with computer viruses. Well at least up the present. Computer viruses can be written by its developer to do anything the developer wishes. For the most part computer viruses have been relatively innocuous. The majority of the computer viruses that you will encounter, at present, in your career as computer user, are of the “Trojan” variety and are not that mean or destructive to your computer. . Trojan antivirus are computer viruses that patiently sit in wait for a signal from a control computer, somewhere in the world, to be part of a large scale computer attack on some remote computer to overwhelm that service and disrupt its function on the internet.. You may have heard such tales in regards to C.N.N. or Amazon having their internet service being knocked out of service maliciously. Believe it or not it is estimated that up to 50 – 60 % of most computers have these Trojan viruses sitting quietly and patiently in their computers and do not know and most likely will never know that they are infected.

The first rules of computer security is that if the computer is used at for storing delicate, sensitive or important data – then that computer should not be attached to the internet or have an internet connection. It’s as simple as that. If you don’t talk then you can never be accused of blabbing.

As an example there was a firm that was allowed access to very confidential government data as part of its business plan. . It was made very clear, by the government agency involved as a sponsor, that this data was most confidential. I f this information was somehow leaked or placed on the internet then dire consequences would occur. What could be a simpler message? And yet in this case, all for the convenience of the owner of the firm, the computer was directly attached to a fax computer. Even of that computer was only connected to the fax max machine computer for a split second that is all it would take for the wrong information to “get out”. Politicians follow the rule of deniability. Why shouldn’t you. ? Make your life trouble free. If the computer is nowhere near the internet in any way shape or form you can never be blamed. Simple as that.

The most important factor in computer antivirus protection is not so much the product used or installed – and there is no shortage of very reasonable computer antivirus products. The most important factor for computer antivirus security protection is that updates for the antivirus be done on a regular basis.

When you purchase a new antivirus product or complete a renewal product that is in essence what you are doing. It as if you are buoying a magazine subscription for the year.

By purchasing the subscription you are now entitled to antivirus updates for the coming year. New computer viruses are coming out “all the time”. It does you little good to be protected from last years plague. You need to be protected from the current viruses that are causing the havoc now.

Make sure that you either have a copy of an antivirus installed that has current virus definitions or if you purchased a commercial product that you have a valid subscription that allows you access to the current up to date virus lists. Next be sure that you run regular full comprehensive antivirus scans to detect and quarantine new and perhaps dangerous computer viruses. More featured commercial antivirus programs may do this automatically.

In the end most of life comes down to preparation and attention to detail. A major role of fire departments is not only to fight fires but fire prevention. Your computer antivirus protections scheme and program should be likewise

CNC And CAD – Computer Aided Design

CNC And CAD – Computer Aided Design

CAD stands for Computer Aided Design or Computer Aided Drafting. CAD was developed in the early 60s. Today it is the premier way to design, develop and optimized products. People use CAD every day to design virtually every product you see. Generally, designers use CAD to design a product, and then produce prints to manufacture that product. A print is a picture of a part or assembly that is very exact. It includes the dimensions and a parts list used to manufacture a product.

CAD is the use of computer based software packages that assist engineers, architects and other design professionals in their designs. CAD is the part of the main designing process and involves both software and sometimes hardware. Current software packages range from 2D vector based drafting systems to 3D solid and surface modelers.

Computer Aided Drafting software packages can generally be broken into two groups. The groups are 2-D drafting packages or 3-D drafting packages. Most all software packages are moving to 3-D design. 3-D design is really the next generation of CAD. Utilizing 3-D design, engineers can make a model of their product. They can then look over this model for any apparent defects before it is ever made.

CAD is used to design, develop and optimize products. CAD is mainly used for the engineering of models and/or drawings of components. It is also used throughout the engineering process from concept to design of products. These products can be used by end consumers or used in other products. For example, you can design a bolt in CAD, and then use it in a Sub-Assembly in a planetary, which is a part of an earth-moving machine. CAD is also used in the design of tools and machinery. Finally, it is used in the design of all types of buildings from sheds to shopping malls.
