Computer Hardware - Guide to the PC Hardware

Your computer is a delicate device that is very complex. Most people never truly understand how the machine works and what it is capable of doing. It handles so much information and at such a lightening fast rate.

You can make it faster though. It can be your own version of the Bionic Woman. With an upgraded memory module, your desktop memory can be bigger, faster and stronger. You will be amazed at the difference.

When it comes to learning about a memory module you may need some background information on the components and acronyms that are frequently used. Take for example the DIMM and the SIMM. One is a duel and the other is a single. But do you know how they work?

The Central Processing Unit accesses the information stored on the DIMM or SIMM. The faster the CPU can access the information, or if it is more readily available, the faster your unit will run.

The DIMM is used for a RAM, or a Random Access Memory upgrade. Desktop computers and notebooks need this RAM and is one of the easiest and cheapest ways to increase your storage. But you will need to know a few things before you can do the upgrade. First, a SIMM uses a 32 bit data path, whereas a DIMM uses a 64 bit data path. Initially, the DIMM is still the faster unit to have running.

If you are looking to replace the DIMM, then you need to know what you are currently using. You will have to add up your storage capacity by counting groups of chips. Chips are measured in bits so you will have to do a little math.

The convert bits into bytes, the formula is the number of bits divided by 8 bytes. The resulting number is the amount of mega bytes that you are currently using.

PC memory upgrades are pretty simple. You simply replace the memory module with the faster processing speed or you can stack the chips and also stack the mother boards. This allows you to utilize one slot and still build up more memory for your computer to use.

You can purchase these chips at a discount computer hardware store and some will even have service departments where you can have a staff member upgrade your computer for a small fee. This may save you time and a hassle, especially if you are not very computer savvy.

In our modern society today, computers and machines have integrated into our lives as one. Practically everything requires some level of technology to function or operate. If I am being asked, “Can we human beings live in a world without computers?”, my answer will be “Yes, but it will be a miserable one.”

Today, almost every household that isn’t living in poverty in the world owns a computer. Therefore, logically it is viable to venture into a business within the computer or computer peripherals industry with the prevailing high-level of demand. Be it an online store or a physical store, you will definitely need a good supplier of computer peripherals to be able to make or sell computers, accessories and parts. One way of doing so is to look for suppliers, not only within a specific geographical boundary, but globally. This is an important proven point to success, as some countries may be manufacturers and producers of some products, where they have the comparative advantage as well as the competitive advantage for some products. Contracting with them will enable you to lower your cost, earn better profits and further expand your business.

Where do you start?

For starters, you can look for computer peripherals suppliers off the internet. Suppliers that want to appeal to worldwide audience usually use the internet as a medium for communication. A search on Google will return a handful of suppliers posting their leads or offers on trade and business-to-business directories. Sign up for these directories and take your time to look them up and do some further research on computer peripherals suppliers, for example. Jumping onto a decision usually will not bear good results, as scammers and cheaters are everywhere.

To prevent being a victim of fraud, you should do more research on a potential supplier for computer peripherals and demand more verification. A visit to the supplier personally before your first transaction will be much more promising, if possible. To learn more about tips, tricks and hints on how to avoid being scammed or identify fraud, do browse through my other articles on EzineArticles.

Alternatively, there are exclusive directories where you have to pay, usually, a one-time fee for its membership. Many will opt for the free directories but these paid directories are a good option to consider as well. With your membership fees, the companies operating these directories are able to employ people to verify every individual supplier for authenticity, as well as keep the information updated. Past customers may also leave ratings or comments on prevailing suppliers so that you can learn about that supplier’s trading behaviour beforehand. Last but not least, a forum for members to discuss about practically anything at all, and a wonderful customer support.

If you are looking for genuine and trusted wholesale suppliers then look no further than Salehoo - a directory containing over 4000 drop ship, wholesale and closeout suppliers that are independently reviewed and rated by eBay Powersellers and Industry experts. Salehoo also purchases off them and reviews each supplier in depth afterwards. To date, Salehoo is one of the fastest growing product sourcing portals on the internet. It contains a database of drop ship, wholesale, closeout and manufacturing suppliers offering thousands of product suppliers to consumers where visitors are allowed to sign up for unlimited and lifetime access to the completely searchable database of products and suppliers. The database is regularly updated, ensuring that the latest retail products are always available for purchase.

As the hold that Sony’s Blu-ray high def DVD format has on the market continues to get stronger in the face of opposition from the competing HD-DVD format, there are a number of things that Sony could do in order to secure a sure victory. One of them is lowering the cost of its Blu-ray disc players.

There’s a lot of evidence to support the idea that this move would make for a sure victory over HD-DVD. Most of this evidence comes in the form of sales statistics. Right now, despite the fact that Blu-ray players cost roughly twice as much as HD-DVD players, there are just as many Blu-ray disc players in American homes as there are HD-DVD players. When you add in the number of Sony’s Play Station 3 video game consoles- which also function as Blu-ray players- the number of Blu-ray players in American homes is significantly higher than the number of HD-DVD players out there. Combine those statistics with the fact that Blu-ray discs have outsold HD-DVD’s in the past couple of months by a margin of over two to one, and it becomes pretty obvious that consumers as a whole like the Blu-ray format more than the HD-DVD format.

There are several reasons why the Blu-ray format may be more popular among consumers than the HD-DVD format. The most obvious technical difference is that the Blu-ray format can encode a lot more data onto each disc than the HD-DVD format can. This translates into longer movies and more bonus features that can be included on Blu-ray discs. Since both High Def DVD formats are also optical discs just like DVD’s and CD’s, there are plenty of computer applications for the technology as well. More data storage capacity translates into being able to deliver more software on each Blu-ray disc than on an HD-DVD disc. Blu-ray is also a better choice for data archiving than HD-DVD. Specifically, the HD-DVD format can only store fifteen gigabytes of data per side of the disc while Blu-ray can store twenty five gigabytes of data per side of the same sized disc! With that kind of a difference, it could be argued that even if HD-DVD was the winner of the format war, it would end up being replaced by something like Blu-ray anyway. Using Blu-ray now, just skips that step.

With the overall popularity of Blu-ray, Sony could secure its win in the format war by lowering the prices of its players. Losses of profits from the players could more than be made up for in coming years by licensing and royalties from having a monopoly on the high def DVD market. Also, as the cost of producing Blu-ray players goes down, Sony will eventually be able to profit on sales of them as well. Unfortunately Sony has been unwilling to make that effort so far, but another company called Funai will force the price of Blu-ray players down by introducing their own Blu-ray players onto the market that will cost around five hundred dollars a piece- a figure much more in line with what HD-DVD players cost.

It’s interesting that a little known company could secure a victory in the format war for Sony by doing what Sony has so far refused to do for itself.

It doesn’t make a difference in what sport or hobby you’re participating in there are constantly folks who blame the tools they’re working with rather than blaming those responsible, themselves. You might also stumble upon this when you are Gaming, gamers will often blame the things they are using when they keep being killed. It maybe that they have spyware on their computer or that they need a new CPU, but what is always overlooked by folk is the gaming mouse they should be using.

Luckily the marketers of these hardware items are seeing this gap in the market and are patching it with gaming mice which can assist to better the gaming style of the gamer which will help their frag count.

Some of the people who have never handled a gaming mouse see the added cost that is often attached to these mouses and think, “can it better my score?” But as any good gamer knows, a gaming mouse is the most crucial tool in your hold most importantly when playing Stalker.

When you compare the specification of a standard mouse and a true Gaming mouse such as the Microsoft Sidewinder you see a great difference in usability that make gaming mice suitable for playing games. DPI is one of the great amount of things to check out when purchasing a mouse for gaming.

If you have ever participated in one of them close quarter gun fights in Stalker where the opposition shifts the mouse that incredibly nimbly that you don’t get a chance. If you should happen to ask what tool they are playing with I’m beyond doubt you will find that they are using a gaming mouse which enables them to have a higher sensitivity.

The resolution is one of the most important point in what ups this sensitivity within the Gaming Mouse, referred to as Dots Per Inch (DPI) in the industry. DPI basically describes the amount of pixels the mouse travels on screen for every inch the mouse travels on the mousemat. Despite saying this, it isn’t 100% true, because software installed on your computer can change the sensitivity of your mouse.

Technical perks aren’t the only innovations in the Gaming Mouse , there are also ergonomic benefits included. Should you have a peek at the config of a gaming mouse you will there are huge alterations to a standard mouse. Gaming mice are created to fit your hand adequately and tones of money are spent to produce gaming mice as comfortable to hold as expected. A mouse should be held much like an expansion of the fingers, much like a sword.

In Closing should you enjoy gaming and want to improve a gaming mouse is one of the most important upgrades you should buy. If you are still using a trackball mouse, you want a clip round the ear and sent running to the nearest PC hardware store.

Not all of us are expected to be complete knowledge holders when it comes to the selection of a desktop computer with a bewildering array of choices at our disposal. Before a prospective buyer goes out for shopping for the latest desktop computers, he is required to decide the reasons of usage. Most of us use a computer to check and send e-mails, perform word processing or browse the Web. If your needs are restricted to these things, try your hand on a simple computer. On the other hand, if you are expected to make extensive use of the computers for transfer of database or editing video files, then you must look for a high-end computer. If gaming is your priority then a multimedia supportive high-end desktop computer is an excellent option for you.

You must give attention to the offered technology support and warranty. There is no use of purchasing additional software and accessories unless you really feel the need to own and use them. If you need to connect external devices such as USB drives to your desktop computer then you must look for computers with USB, FireWire, audio & video connectors and ports. Do not buy low-quality replicas as they will minimize the life span of your computer. Always make a point to look for the LCD monitor interface and stay away from fancy keyboards with useless extra buttons.

There must be simply no compromises on the processor speed and quality. Your computer must have ample empty memory space to allow smooth functioning of its applications. Install a good anti-virus; get a reliable motherboard to attain advanced solutions with complete ease and perfection.

Fiber optic cable installation is a very special task that only trained professionals can do it quickly and correctly. This is determined by fiber’s fragile structure and highly sensitive to microbending and macrobending loss.

However, most of the techniques of fiber optic cable installation has been borrowed from those used for copper cables. And currently the majority of fiber cable contractors come from the copper network background.

Fiber cables can be divided into two big groups: outdoor cables and indoor cables. Outdoor cables are laid along rights of way leased or owned by telecommunication carriers, and they are well marked after the cables are installed. The telecommunication carriers have their own team of cable installers and they seldom outsource the job to independent contractors.

Most independent fiber cable installation contractors install indoor cables most of the time. Indoor fiber cables are mostly used as the backbone for campus networks, enterprise LAN systems and etc.

And there is the submarine cable category. They are laid from ships built for that purpose. They are only used by the big global network backbone builders.

But actually there are many small divisions within each group. So let’s examine them one by one.

1. Submarine cables. Submarine cables are laid from ships built for that purpose. They are buried in a trench dug on the sea floor at depths of less than 200 meters. In areas deeper than that, submarine cables are directly laid on the ocean floor.

2. Direct-buried fiber cables. Direct-buried cables are also called armored cables. They have aluminum foil wrapped around for mechanical protection from rodent bite and outside forces. They are laid in a deep trench dug with a cable plow and then covered with dirt.

3. For outdoor cables excluding direct-buried cables, cable ducts are needed. Cable ducts are plastic tubes which provides a path and protection for outdoor cables. They are buried in trenches and then covered with dirt. Cable ducts have a variety of sizes and flexibility, they can range from one inch up to a 6~10 inches. Some are flexible while the others are pretty rigid.

4. Cable ducts are buried first without any fiber cables inside. They can be routed directly between two endpoints or through a series of access points at manholes.

5. Outdoor cables are then pulled through the cable ducts with pulling rope. The pulling rope is attached to the strength member of the cable and then pulled from the destination point. You should never pull the fibers directly since that will break the fibers easily and result in a useless broken cable for you.

5. And then there are aerial cables. One type of aerial cable has a messenger line built-in which provides mechanical support and they can be hanged on poles without any lashing. This type of aerial cable is called figure 8 or self-supporting cable. Other types of aerial cables have to be lashed with a special lashing wire running around both the cable and the separate messenger wire.

6. Indoor cables can be installed within walls, through cable risers, or elsewhere in buildings. Note: only special under carpet fiber cable should be used for laying on the floor where people walk.

7. A special type of indoor cable is called plenum cable. They have special formulated out jacket material for fire rating. Only plenum cables can be used in air return spaces for the VAC system.

We’ve covered a lot about fiber cable installation in this short article. By warned - you should always browse some training material on fiber cable installation before try it yourself!

A slow running computer can be a huge pain when you are trying to get a job done. The software runs slow, the load times are unbearably long and forget about playing any computers video games.

If this is happening to you and you want your computer to operate at a faster speed, then you need a memory upgrade to make your computer zip along at lightening fast speeds. You will be able to run several applications at once, listen to your MP3 players music and get to play those computer games you just cannot live without!

Upgrading your computer’s memory is a great way to run programs faster and speed up the overall use of your computer. A memory upgrade is relatively inexpensive and real easy to install. The hardest part is finding out what kind of memory you need and selecting the right type of storage for the speed you wish. There are four types of memory which are: RDRAM, DDR2 SDRAM, DDR SDRAM, and SDR SDRAM.

Step number two is to go to a discount computer hardware store to purchase your new storage card. You want to upgrade to the highest capacity you can afford. Remember that more storage means more speed and efficiency for your pc. You do not want to have to purchase a new card every few months. Go ahead and splurge a little. This is the cheapest way to improve your computer’s speed.

Most computers allow you to use generic memory cards. Once you have your new memory card it is then time to open that baby up. Remove the cover to your pc. If you have an available slot, then all you have to do is plug in the new desktop storage card you purchased. If there are no open slots left, then you will need to remove the old one and replace it with the generic one card or a pc specific storage card.

So now you see how easy a memory upgrade can actually be. Before you consider getting rid of your computer for a faster model, do an upgrade and you will see a noticeable difference in how fast your processing speed is. It is a simple plug in and go swap of the old storage module and the new version. Just make sure to get as much storage as you can possibly afford so you do not have to replace the memory again any time soon.

Duplication

Unfortunately, not all duplicated DVD discs will play in all DVD players or computer disc drives. Unlike CD ROM’s, where all the manufacturers worked specifications out in advance, the manufacturers of DVD discs, players and computer drives did not agree on one standard to use. To add to the potential problems, duplicated DVD’s are burned with a laser impression and are not as readable as replicated DVD’s.

The good news is that newer DVD players and computer drives are being made to read most types of DVD’s, resulting in fewer compatibility issues. However, problems still exist with some players - depending on how much ‘homework’ the manufacturer did before producing the player. Chances are that if you experience difficulty in playing a duplicated DVD in a particular player, it will work in another.

Replication

Replicated DVD’s, such as those rented at Blockbusters are created by first making a ’stamper’ from the original DVD, and the copies are literally stamped with a physical impression of the data. The stamped impression will last longer and is guaranteed to play on all players and computers. Unfortunately, it’s generally not cost effective to replicate DVD’s unless you’re making 1000 or more copies, as it costs hundreds of dollars just to make the stamper. Some companies will replicate as few as 500 discs, but you may pay a premium for smaller quantities.

Go to Google or another search engine and look up ‘DVD compatibility’ to learn more about the scope of the problem and find out which models have the most problems.

Here’s a list to help you decide which way to go:

DVD Duplication

• Cost effective for quantities UNDER 1000

• Uses a laser to burn data onto the disc

• Approximately 1 week or less turnaround time, depending on quantity, packaging, etc.

• NOT compatible with all DVD players

• Thermal or inkjet printing on face of disc. Can also laser print a paper label which can be affixed to the disc

DVD Replication

• Cost effective for quantities of 1000 and UP

• Uses a glass master to stamp information on to the disc

• Approximately 3 week turnaround time

• Professional quality. 100% compatibility with ALL DVD players

• Silkscreen-printing on disc and professional quality packaging

Identity authentication is a component of identifying identity fraud risk. Advances in technology through fingerprint biometric services have lead to biometric verification becoming a potential tool in identity verification.

What is identity authentication? The authentication process involves validating the identity presented is the actual person. It goes further than typical identity verification and seeks a confirmation that the person presenting the ID accurately is the person being represented by the ID.

Beyond Paper Identification:
The problem with paper identification is it is not tamperproof. Efforts have been made by states to increase security of state-issued ID cards; however, those looking to perpetrate fraud have been able to keep up with the technology changes. How can you keep up with a criminal element dedicated to staying one step ahead of paper identification cards? The answer, you need to change the identity verification process to an identity authentication process.

Examine the below identity verification system. If a system was able to achieve the below, what would the result be for potential identity fraud risk?

- Electronically capturing photo IDs.

- Detecting false or tampered IDs.

- Connecting IDs to fingerprints.

- Verifying identity.

- Automatically verifying age.

- Retaining comprehensive transaction history.

The above demonstrates the need for comprehensive identity authentication systems to help mitigate identity fraud risk. A secondary requirement becomes apparent when you look at the steps required by comprehensive identity authentication systems–the need for speed of validation. As a result the system needs to be both accurate and efficient. How can this be achieved in point of service situations?

Multiple Verifications Mitigate Identity Fraud:
There is a statistical assumption that the more verification checks performed, the better your chances are that you are mitigating identity fraud risk. To perform multiple verifications will require an additional expenditure of time. To keep the process of identity authentication accurate and efficient, what verifications checks need to be performed? In the previously list there was an item called “Connecting IDs to fingerprints,” this verification action can help hold the key to identity authentication.

Connecting IDs to Fingerprints, the Role of Fingerprint Biometric Verification:
Advances in fingerprint biometric technology have resulted in the ability to conduct biometric verification. Some solutions have the ability to capture and link a fingerprint to a single ID record. The result is a mitigation of identity fraud risk and fraud risk resulting from an individual attempting to use multiple identities.

Fingerprint Biometric technology provides identity resolution, or the ability to match one person to one identity. The ability to find identity fraud patterns also prevents individual users from making multiple ID fraud attempts. A final benefit of fingerprint biometrics is that the fingerprint images are stored and available to law enforcement and prosecution of identity fraud suspects.

Uses of Biometric Verification:
The ability for fingerprint biometrics to connect a single fingerprint to a single identity becomes desirable in various business applications. Biometric verification can mitigate identity fraud risk by linking a fingerprint to a single stored identity. This technology becomes desirable in situations where high security is required for identity authentication prior to new business being conducted. Applications such as opening a high-value new account or authenticating an identity through repeat transactions illustrate the need to implement biometric verification.
