Who Invented Dell Computers?

The invention and the history of the Dell computer is quite interesting. First of all, it was in 1984 when Michael Dell, a student at the University of Texas at Austin, created the company PC's Limited. He only had a starting capital of $ 1,000. So what he did was started working out of his dorm room to build personal computers made from stock components. These computers were to be IBM compatible because that was the standard at that time. If a computer were to function with various pieces of hardware, it needed to be IMB compatible.

It is when Michael Dell figured that selling computers directly to customers to determine customer need that he dropped out of college. His family then extended him the $ 300,000 in expansion capital that he needed to make his business take off.

A success

It was in 1985 that the Turbo PC was developed and it sold for less than $ 800. It contained an Intel 8088 processor that ran at 8 MHz, which is significantly slower than the computers that we use today. Computers today are running in gigahertz, which are hundreds and even thousands of times faster than the 8 MHz processor that Michael Dell was installing in his computers at the time. But the truth is that this was the best that could be done in 1985. The technology was developing.

But there was an aspect of PC's Limited that was unique from the rest and continues to be this way today. It is the fact that customers could order their computers rather than buy a computer that was already assembled. This allowed individuals to receive computers at lower prices than what they could get with their competitors. This definitely worked because PC's Limited grossed $ 73 million in its first year of trading.

The beginning of Dell

It was in 1988 that PC's Limited became Dell. Prior to that, the company already had 11 international operations occurring, so the company was quite large. There were on site services set up to compensate for the lack of businesses acting as service centers for Dell computers. It was in 1990 that Dell attempted to sell through club houses, but had very little success with this. So it is then that Dell went right back to its direct to customer sales.

In 1996, Dell started selling computers on its website. An individual could go onto the website and custom design their computer so that it would be built to their specifications. From there, it would be shipped to the customer's home. Financing was made available so that individuals would be able to acquire their computers easily.

In 1999, Dell became the largest personal computer seller when they took over Compaq computers. Their revenue topped $ 25 billion in 2002. Also in 2002, Dell started selling televisions and other electronic items. They now have Dell brand printers, LCD TVs, and much more. Because of the expansion beyond computers, Dell was changed to Dell Inc. In 2003.

It is amazing that this billion dollar company started in a dorm room with $ 1000 in starting capital. And Michael Dell has always stood by the principles of letting individuals have the capability to design their own machine. Although there are Dell computers now sold in various retail outlets, a person can still go to the website and design the machine of their dreams. And Dell also offers a lot of assistance for individuals needing help with their computers. They offer on-site services and so much more for the computer user so that they can have the best experience possible.

How to Retrieve Deleted Text Messages & Not Go Crazy in the Process

It’s happened to all of us. We’ve deleted a text message only to realize a short while later that we either deleted the wrong message, or we need to retrieve information off one of the deleted text messages. We then frantically search out ways online how to retrieve deleted text messages hoping to find an easy solution. We pour through websites pulling our hair out because we can’t find an easy solution.

Ultimately we walk away dismayed because either we were not able to find any solutions on how to retrieve deleted text messages, or the solutions we found seemed to require so much “detective” work, that the solution itself should be on a an episode of CSI.

Are there really any “easy” ways to retrieve deleted messages?

The good news is that YES, there are a couple options that do exist which enable anyone to easily recover deleted texts, and both are not only very affordable, but both work exactly as advertised.

Before we dig into the solutions, there is one solution that is often discussed, which does not work, although many people do still talk about it.

What does NOT work?

Going to your own phone carrier is not going to be a viable option. Yes, they are required by law to keep records of your communication (SMS, call, etc.), but they are not required to turn over their logs to you, unless requested by a court of law. You cannot call up AT&T, Verizon or Sprint and tell them you want to retrieve a deleted text message from last week because there is something really important within the contents of the message. It just wont work.

The only information AT&T, Verizon, Sprint, or any other cell phone carrier is going to provide you is the number, date, and time of a call or message. You can plead all you want, but they will not be able to do anything, so it’s not worth your time to attempt this approach.

What DOES work?

There are actually two options available for anyone who is looking for information on how to retrieve deleted text messages. These options rank from the “quick and easy” to the more difficult, but also the most effective.

1) Quick & easy method.

The ‘quick & easy method’ is to buy a SIM card reader, often referred to as a SIM card spy device. This device looks like a USB reader, and the way it works is you remove the SIM card out of your phone, and then place the SIM card into the SIM card reader, and then plug the reader into your computer. Using the included software (of the SIM card reader), you’ll be able to immediately retrieve and read deleted text messages. The time frame will vary, based on what new information is overwritten on the SIM card, but you’ll at least be able to retrieve and read the last 15-20 messages and scan through your call history and contacts, even if they were all deleted.

Positives of this approach?

  • Very easy.
  • Enables you to quickly recover deleted messages.
  • Does not require software to be installed prior to the message being deleted.

Negatives of this approach?

  • A bit costly.
  • Limited cell phone support.
  • Does not work on CDMA networks.

2) More difficult, but most effective method.

The more difficult, but most effective method’ is to purchase a cell phone monitoring app that is often used to spy on cheating spouses, monitor teen cell phone use, track cell phone location, and locate missing or stolen cell phones. These apps (often called spy apps or spy phone software) are often used by people who want an easy and convenient way to back up and store all their own personal cell phone data. The reason why this method is fast becoming a popular way to back up their own personal cell phone data is because everything happens automatically. There is no “syncing” required, or any buttons or settings to worry about. Your cell phone data (text messages, call history, etc.) are automatically backed up every single day. This means if you ever delete a text message, and then need to quickly recover it, all you have to do is log onto your account and then in just a few clicks, you’ll have full contents of every message that was either sent or received from your phone. In addition, you’ll get access to all your call logs and contacts.

The reason why this is a more difficult method, is because it requires that you download the software from your cell phone’s web browser and install the application on your phone. Not everyone is comfortable downloading cell phone apps from the internet using their phone’s web browser. However, once you do complete the download, the actual installation is similar to installing an app on your computer. If you are willing to roll the dice and go with this method, you’ll be very happy with the results. It’s essentially a real time person back up solution that requires absolutely ZERO work on your part. Everything is done for you. The only drawback with this approach is that it does require you to install the software BEFORE you delete the text message that you want to retrieve. This means you need to be proactive and install the software ahead of time.

Positives of this approach?

  • Extremely effective.
  • Affordable.
  • Full contents of text messages are retrieved.
  • Large amount of cell phones are supported, including the popular models such as Android, BlackBerry, iPhone, Nokia, and more.

Negatives of this approach?

  • Can be difficult if not familiar with installing cell phone apps.
  • Software must be installed prior to message being deleted.
  • Requires a data connection such as 3G or Edge
  • May increase data fees if a large amount of text messages are sent on a daily basis.

There you go. Now you know how to retrieve deleted text messages using a couple different approaches. The next time someone asks you how to retrieve deleted text messages, you’ll know what options exist, and which one is the best for that particular situation.

Good luck!

The Importance Of Excel In The Workplace

Excel is perhaps the most important computer software program used in the workplace today. That’s why so many workers and prospective employees are required to learn Excel in order to enter or remain in the workplace.

From the viewpoint of the employer, particularly those in the field of information systems, the use of Excel as an end-user computing tool is essential. Not only are many business professionals using Excel to perform everyday functional tasks in the workplace, an increasing number of employers rely on Excel for decision support.

In general, Excel dominates the spreadsheet product industry with a market share estimated at 90 percent. Excel 2007 has the capacity for spreadsheets of up to a million rows by 16,000 columns, enabling the user to import and work with massive amounts of data and achieve faster calculation performance than ever before.

Outside the workplace, Excel is in broad use for everyday problem solving.

Let’s say you have a home office. You can use Excel to calculate sales tax on a purchase, calculate the cost of a trip by car, create a temperature converter, calculate the price of pizza per square inch and do analysis of inputted data. You can track your debt, income and assets, determine your debt to income ratio, calculate your net worth, and use this information to prepare for the process of applying for a mortgage on a new house. The personal uses for Excel are almost as endless as the business uses for this software – and an Excel tutorial delves into the practical uses of the program for personal and business use.

The use of spreadsheets on computers is not new. Spreadsheets, in electronic form, have been in existence since before the introduction of the personal computer. Forerunners to Excel and Lotus 1-2-3 were packages such as VisiCalc, developed and modeled on the accountant’s financial ledger. Since 1987, spreadsheet programs have been impacting the business world. Along the way, computerized spreadsheets have become a pervasive and increasingly effective tool for comparative data analysis throughout the world.

Today, end users employ Excel to create and modify spreadsheets as well as to author web pages with links and complex formatting specifications. They create macros and scripts. While some of these programs are small, one-shot calculations, many are much more critical and affect significant financial decisions and business transactions.

Widely used by businesses, service agencies, volunteer groups, private sector organizations, scientists, students, educators, trainers, researchers, journalists, accountants and others, Microsoft Excel has become a staple of end users and business professionals.

The beauty of Excel is that it can be used as a receiver of workplace or business data, or as a calculator, a decision support tool, a data converter or even a display spreadsheet for information interpretation. Excel can create a chart or graph, operate in conjunction with Mail Merge functions, import data from the Internet, create a concept map and sequentially rank information by importance.

Excel offers new data analysis and visualization tools that assist in analyzing information, spotting trends and accessing information more easily than in the past. Using conditional formatting with rich data display schemes, you can evaluate and illustrate important trends and highlight exceptions with colored gradients, data bars and icons.

Indeed, Excel can be customized to perform such a wide variety of functions that many businesses can’t operate without it. Excel training has become mandatory in many workplaces; in fact, computer software training is a must for any workplace trying to keep up with the times.

Let’s say you’re an employer with 97 workers, 17 of whom called in sick today, and you want to know the percentage represented by absentees. Excel can do that. You can learn Excel and use it to determine the ratio of male to female employees, the percentage of minorities on the payroll, and the ranking of each worker by compensation package amount, including the percentages of that package according to pay and benefits. You can use Excel to keep track of production by department, information that may assist you in future development plans. You can create additional spreadsheets to track data on vendors and customers while maintaining an ongoing inventory of product stock.

Let’s say you want to know your business production versus cost. You don’t have to be a math wiz – you just have to learn Excel. Excel allows you to input all of the data, analyze it, sort it according to your customized format, and display the results with color, shading, backgrounds, icons and other gimmicks that offer time-saving assistance in later locating precisely the information desired. If this spreadsheet is for presentation purposes, Excel helps you put it together in such a visually appealing way that the data may seem to pop and sparkle.

The single most important thing an employer may do is learn Excel – it is one of the most essential tools of the workplace.

Build Your Own Tree House – Pros and Cons, Fasteners and Hardware

Tree houses are fun, bonding activities you can do with your friends or family, and can provide a unique and ideal hangout spot surrounded by Mother nature. One of the biggest differences in my opinion, between tree houses and other on-ground add-ons you can build on your property, is the fact that a house up in the trees sways – to varying degrees depending on the height and size of the Tree and branches – and so can add a unique and soothing feel.

There are several prerequisites that must be met before this particular project would be considered feasible for you. The first ones are also the most obvious:

  1. Do you have a suitable tree with your property on which you can construct your tree house? This question may be ambiguous to some, as what kind of tree exactly is considered suitable? Well, this depends largely on the size of the structure in question, as well as the expected load – number of people, furnishings, etc. The larger your tree house is, the larger your tree needs to be.
  2. How are you with heights? Now is not a good time to kid yourself or anyone else if you happen to be abnormally scared of heights! We're all scared of heights to varying degrees, but if you lack the courage or ability to comfortably work at the needed height, this project may not be for you. Granted, it can be built relatively low to the ground as well and still be called a "tree house" – in which case, this may not apply.

Now that we have those out of the way, we can get into the other aspects of building. When compared with a structure on the ground, a tree house may somehow seem like a simpler project due to the fact that some of us have grown up "throwing" little makeshift tree houses up here and there. However, it's important to remember that any halfway decent structure, whether on the ground or up in a tree, requires careful planning and implementation of standard safety code.

Here are some other questions you should ask yourself before concluding the planning stage:

  1. What will I use the tree house for? Depending on your answer, you may want a roof and walls, or you may find it unnecessary. In either case, a rail and / or walls at least a meter high is recommended for safety.
  2. How long do I want it to last? You may think that the answer to this question is obvious, but you should understand that the lifespan of your tree house depends heavily on the materials you use and the quality and number of layers of your protective stain. Tree houses, by virtue of their definition, stand within and under the canopy of the tree in which they are built. Because of this, they are more susceptible to premature rot due to the prolonged shade and humid nature of their environment. The fallen leaves and branches scattered across the deck also serve as decay-accelerators unless they are regularly swept off.

Foundation and Floor-shape

One of the unique beauties of a tree house is the fact that you can simply build around the various branches leaving them exposed within your tree house, enhancing the "natural" atmosphere. As with an on-ground structure, you should start with building your base and floor. You may face complications with the shape of your floor due to the limitations of suitable branches to base off of.

Because of this, there's a possibility you may have to set up for a non-square shape. This may be what you want, or this may be a problem for you. In any case, you should understand that there are some restrictions placed upon you by the particular tree you're working with. All branches used for a foundation should be able to single-handedly carry several hundred pounds, and more if you're expecting higher traffic.

Tree Wood Density and Fastener Quality

Large tree houses that weigh more than the collective weight of their occupants should be carefully designed , as various factors such as the hardness of the tree and fastener quality and design come more into play. Wood will compress where the fasteners connect to the tree to varying degrees based on the hardness of the tree in question, causing a sinking of the tree house.

Professional-grade Tree house Fasteners – Are they Necessary?

There are various tree house fasteners available on the market today specially manufactured for their unique needs. However, the question invariably arises as to how necessary these customized bolts and brackets are in comparison to normal ones found in home centers due to their price. They often cost between one and several hundred dollars each!

The first thing to bear in mind when contemplating the pros and cons of these rather pricey pieces of hardware is that trees are living organizations, and are still growing, moving, and changing shape. Therefore, your tree house and the hardware on which it is mounted must accommodate this movement. Simply bolting the beams into the tree's branches results in a fixed attachment that will force the tree to either pull the screw through the beam or try to grow around the beam.

The first of the two will result in a sudden and dangerous failure , while the second will result in an unhealthy and unnatural growth around the beam, potentially causing disease and decay to set in. Custom bolts and brackets are made with a certain allowance for tree growth, with a section of the bolt that is embedded deep in the tree's heartwood and a large shank that allows axial movement coupled with a female part that is attached to the beam.

So to answer the question of whether these expensive custom parts are necessary, the short answer is yes, and no. Yes, if you lack the know-how to find parts that will accomplish the same purpose as the professional parts do, and no, if you do, and do not require your tree house to last for fifty years. Home centers sell bolts and hardware with large diameters and lengths which can be used, but the entire shank can not be threaded.

The half or so that is embedded into the tree must be threaded, but the reminder that acts as the cushion to compensate for tree-growth must be smooth. You also need a female piece that fits around the smooth shank that has a bracket that can be screwed into your beam. This female bracket then has the freedom to slide along the axis of the smooth bolt shank as the tree grows in girth. All parts should be stainless steel as well – others may corrode to failure.

Obviously, the big tree house building companies would disagree with the above opinion, and the ideal is to buy these parts. I'm just offering an alternative for those who do not have a large budget but still want to construct a safe and environmentally-friendly tree house. There is also a chance you will not be able to find hardware that meets the criteria, leaving you with no other choice.

The professional criterion when it comes to fastening your tree house to your tree seems to be "perch, do not pin". I agree whole-heartedly with this principle and any alternative I save above should not contradict this. But not everyone looking to build a tree house is willing to spend tens of thousands of dollars, so, your budget is a primary factor in determining the quality as well as what kind you would build.

In any case, it should be a safe and fun place to accommodate whatever activities you envision. Taking into consideration the damage inflicted on the tree as well as future complications that may arrise such as those mentioned above when planning, is simply the responsible and consider course of action.

Have you ever been asked to log in as soon as you enter office and the main gate of the office has a Biometric machine that takes in your finger prints and allows you to enter the office premise? Yes, these are the time and attendance software being installed in a company.

Biometrics consists of methods for uniquely identifying a person (human being) by his/her physical or behavioral traits. There are many biometric software available in market for such purpose and their use is widely known. One such use is Biometric time and attendance management software.

Those days are gone when we had to punch in cards or sign into a register to tell the other person that we are present. Just as paper checking has been changed from manual to computerized, identifying a person and letting him in your office has been changed from manual to biometrics.

There are many benefits of having such methodology in your office. Such as:

• Accurate timing: When a person looks at his watch and enters the time there is a slight chance that he may see the wrong timing and write. Whereas with biometric time and attendance software there is no possibility of such mistake. The user does not need to see or check the time, it automatically gets logged in.

• Less error: There is no scope of human error here.

• Profit to company: If it’s accurate and correct the company will definitely gain from it.

As everything has a good and bad side this too has its disadvantages, such as:

• Extra cost to company: Biometric software and machine cost a lot more, so installing such software need a good investment money wise.

• Extra management: Remember when every employee is logging his own timing when he comes or leaves; there is no extra management here. But, if you are putting a machine there has to be taken some care of it.

Biometrics time and management software is really helpful when creating payrolls for employees. Once a definite timing has been registered you don’t need to think twice before creating the employees pay.

Examples Of Spyware And What They Are

Spyware is a general term used to describe software that performs certain behaviors such as advertising, collecting personal information, or changing the configuration of your computer, generally without appropriately obtaining your consent first.

Spyware is often associated with software that displays advertisements (called adware) or software that tracks personal or sensitive information.

That does not mean all software that provides ads or tracks your online activities is bad. For example, you might sign up for a free music service, but you “pay” for the service by agreeing to receive targeted ads. If you understand the terms and agree to them, you may have decided that it is a fair tradeoff. You might also agree to let the company track your online activities to determine which ads to show you.

Other kinds of Spyware make changes to your computer that can be annoying and can cause your computer slow down or crash.

These programs can change your Web browsers home page or search page, or add additional components to your browser you don’t need or want. These programs also make it very difficult for you to change your settings back to the way you originally had them.

The key in all cases is whether or not you (or someone who uses your computer) understand what the software will do and have agreed to install the software on your computer.

There are a number of ways Spyware or other unwanted software can get on your computer. A common trick is to covertly install the software during the installation of other software you want such as a music or video file sharing program.

Any software that covertly gathers user information through the user’s Internet connection without his or her knowledge, usually for advertising purposes. Spyware applications are typically bundled as a hidden component of freeware or shareware programs that can be downloaded from the Internet; however, it should be noted that the majority of shareware and freeware applications do not come with SpyWare. Once installed, the Spyware monitors user activity on the Internet and transmits that information in the background to someone else. Spyware can also gather information about e-mail addresses and even passwords and credit card numbers

Aside from the questions of ethics and privacy, SpyWare steals from the user by using the computer’s memory resources and also by eating bandwidth as it sends information back to the spy ware’s home base via the user’s Internet connection. Because SpyWare is using memory and system resources, the applications running in the background can lead to system crashes or general system instability.

Because SpyWare exists as independent executable programs, they have the ability to monitor keystrokes, scan files on the hard drive, snoop other applications, such as chat programs or word processors, install other SpyWare programs, read cookies, change the default home page on the Web browser, consistently relaying this information back to the SpyWare author who will either use it for advertising/marketing purposes or sell the information to another party.

Licensing agreements that accompany software downloads sometimes warn the user that a SpyWare program will be installed along with the requested software, but the licensing agreements may not always be read completely because the notice of a SpyWare installation is often couched in obtuse, hard-to-read legal disclaimers.

Examples of SpyWare

These common SpyWare programs illustrate the diversity of behaviors found in these attacks. Note that as with computer viruses, researchers give names to SpyWare programs which may not be used by their creators. Programs may be grouped into “families” based not on shared program code, but on common behaviors, or by “following the money” of apparent financial or business connections. For instance, a number of the SpyWare programs distributed by Claria are collectively known as “Gator”. Likewise, programs which are frequently installed together may be described as parts of the same SpyWare package, even if they function separately.
