There are many choices in the computer market with different models and designs all created for different benefits and uses. Computer manufacturers design systems made for all possible uses with a variety of features to perform any type of computing task. There are also different models and designs available and a whole mobile sector that makes it easy to compute from anywhere without being tied to a plug.

As far as desktop systems go there are two main designs, the all-in-one and the traditional desktop computer system. Each has its own benefits and pros and cons. The choice sometimes comes down to how and for what the computer will be primarily used.

The all-in-one model is where the monitor and CPU are part of one unit so you do not have a CPU tower and a separate monitor that takes up more space as is the case with the traditional desktop system. The all-in-one eliminates the bulky and messy cables and connection wires that are part of the traditional set up.

There are some important differences between an all-in-one desktop computer and a traditional desktop computer. The traditional desktop is big and bulky. It can take up a lot of room, especially when you have a limited amount of space, with the CPU tower, plus the monitor as well as other peripherals, such as a printer or scanner.

The all-in-one also has no cables except for the power cord and peripheral cables and so it creates much less clutter under your desk. Overall the all-in-one desktop is able to provide you with much more space because of its compactness and size, which makes it much more space friendly. Another benefit of them is the fact that they come with notebook computer components, which require less power and generate less heat and so they save on power, which saves some money.

There are some cons with the all-in-one models. As opposed to the traditional desktop computer, which has plenty of room for expansion such as adding a hard drive or more memory, the compactness of the all-in-one leaves little room for it. So while the all-in-one is more efficient, it is less upgradeable. But unless you need a lot of features or you are a power user, the all-in-one because is a great choice for aesthetics, space and power saving benefits. However, for extreme gamers or power users the traditional system is a better choice.

A computer device is made up of two major parts; Hardware and Software.
Hardware is the physical components of a computer like a monitor or the mouse, which you can actually touch. Computer Software are programs or applications that give instruction to hardware on what to do, and can not be physically touched. The best way to think about this concept, is to picture a human body, all physical parts such as arms, legs, heart, eyes, etc are the Hardware and the synapses made by the brain that send information to the rest of the body would be the Software.

The following are examples the hardware of our modern day computers:
-Monitor
-Motherboard
-CPU
-RAM Memory
-Expansion card
-Power supply
-Optical disk drive
-Hard Disk
-Keyboard
-Mouse

The Monitor is usually known as the computer screen and displays what is being processed and accessed.

The Motherboard holds the major components of the computer system and provides connectors to peripherals (keyboard, mouse). It is also known as the system, main or logic board.

The CPU carries out the instructions of programs and other computer functions.

The RAM (random-access memory) is the way to store data on a computer on circuits that can be accessed in any order. Types of RAM; ROM and some flash memory.

The Expansion card is a circuit board that is inserted into the expansion slot of the mother board and adds functionality or even memory to a computer system.

The Power Supply provides the power or electricity to the computer.

The Optical Disk Drive is where you insert you CD or DVD into the computer.

It uses a laser or waves to read or write information to and from the disk.

The Hard Disk stores data that is encoded digitally.

The Keyboard is the device used to input information and commands into the computer system. It resembles a typewriters keyboard.

The mouse is the device used to point to items on the screen.

There are many parts that make up a computer and there is no better way than e-learninge-learning to learn how to use the integration of both computer hardware and software. When the convenience of learning from home or the location of your choice is the only option, the best way to go is e-learning.

Elizabeth Whelan, President of the American Council on Science and Health (ACSH) posted a great entry on ACSHs Health Facts and Fears blog on the growing attempts by activist groups to convince the EPA to ban atrazine due to cancer claims and other health concerns.

Atrazine is one of the most widely used herbicides in the world. It helps farmers fight weeds on corn, sugar cane and other crops, leading to dramatic increases in crop yields. Without it, our food supply would be in jeopardy. Activists want the public to believe that atrazine causes cancer and birth defects, but its simply not true. Whelan writes:

“Atrazines health and safety record is stellar. The Safe Drinking Water Act requires monitoring for a multitude of chemicals, including atrazine. Levels of atrazine in U.S. waters are well within the federal lifetime drinking water standard a level containing a 1,000-fold safety buffer. The Environmental Protection Agency in 2006 completed a 12-year review involving 60,000 different studies and concluded that the current use of atrazine poses “no harm” to the general population infants, children and adults. According to this same regulatory agency (which oversees pesticide use) atrazine is “one of the most closely examined pesticides in the marketplace.”

Whelan points out that many activists are not willing to accept this assessment and were able to cast doubts upon the issue with the EPA. As a result, last fall the EPA announced it would initiate a re-re-re-evaluation of atrazine and health. These activists will not be happy until the EPA bans this herbicide, which would then open the door for activists to attack more chemicals, claiming they are unsafe.

Finally, Whelan points to the media for “scaring” the public into thinking that these “chemicals” are unsafe and that the manner in which they are evaluated should be changed:

“Many of the recent media chemical scares, like the two hour “toxic” presentation on CNN, argue that a) there are tens of thousands of “chemicals” out there; and b) the current government policy, assuming these chemicals are safe until contrary evidence was presented, must be reversed so that a chemical is considered hazardous until it is “proven safe.” But how do you prove something to be safe? Its like trying to prove a negative it cant be done. The example of atrazine with decades of safe use, thousands of studies that found no harm to humans and years of getting a green light from EPA (which is not known for understating chemical risks) leaves us with the question: After all these evaluations and years of use, if atrazine doesnt meet the criteria for “safety,” what chemical possibly could?”

Sadly, its not uncommon to have computer chairs snap under you. You might not even be that heavy, but chairs just arent made as well these days! Remember back when they were all metal? Those suckers withstood anything. These days, plastic is all youll find in most computer chairs. Overweight people tend to have even more problems since chairs often last only a few weeks before something breaks.

While you can keep using the chair without an arm or even if the back cracks and ends up at a weird angle (yes, this happens to many of us!), once the support column or one of the wheels or base legs goes, youre pretty much hooped. Many people cobble together Frankenchairs, made from a base that still functions with a seat that is still intact, just to save a bit of money. It might seem silly, but if you have computer chairs break on you every couple of months, this is what happens.

So, why do your chairs break? Here are three main reasons:

1. Its not built for weight. Most computer chairs are designed to withstand 150-200 lbs. So, if you weigh anything over that, your chair isnt going to last very long. Thats why you might want to look at computer chairs for overweight people, which can be rated for up to 500 lbs.

2. The material is poorly made. Unfortunately, there arent many high standards in the world of office chairs. Overweight people have discovered that plastic simply isnt designed to withstand much weight . . . it twists and bends and eventually cracks under the stress. These chairs are often stamped out of low cost plastic, which is not sturdy enough.

3. You move too much. When a computer chair is working properly, it will roll smoothly over the floor. However, poorly built chairs cant hold up to the weight. They will sink down, essentially crushing the wheels against the caps and the wheels wont roll. When this happens, you will end up jerking the chair to move it and that puts extra stress on the already fragile joints.

Often its a combination of these three factors that causes a computer chair to give way. You will want to make sure that you choose your chair very carefully. There are a number of designs in computer chairs for overweight people that will hold more and resist more action. Even if you arent obese, choosing a sturdier chair can be a good investment in the long run.

There are some good beginner singing lessons software programs out there if you look in the right places. Some programs don’t live up to their hype. I stick with the ones, which have a long established track record.

Just like anything, I always make sure to seek others, who have used something before I consider buying it. There are a couple of good learn singing guides you can download now, which eliminate the need for expensive vocal coaches. For me, singing lessons got expensive and I felt like I didn’t need them anymore to just review what we already learned.

With a decent beginner singing lessons software program, you don’t have to learn something one week with a teacher and then pay them again to review your progress and go over the same stuff.

I can usually hear my own progress as a singer or I can record myself to hear the progress. With a decent instruction program, they will have recording software and ways to play back what you just practiced into the mic. There are also ways to improve with singing games, which come with some programs. This might suit some aspiring singers more than hiring expensive vocal coaches.

Don’t get me wrong, some vocal coaches are absolutely fantastic, but who can afford them on a weekly basis? I sure couldn’t as an aspiring musician with a decent pay check coming from my day job. That’s why some teachers will even tell you they’re finished with you after you have four or five lessons. This is admirable when teachers do this because they could keep trying to milk you for more money.

So there are a few good programs out there just find which one has the best reputation and which one is created by someone well knows in singing circles. That way, you are less likely to be disappointed with the beginner singing lessons software that you decide to acquire.

One of the requirements of entering a science fair is to complete a science fair project report. To be graded or scored well, the student needs to use the correct format, voice, tone and style, and they will need to include the right elements. Fortunately, all of these things are easy to accomplish once you know what is expected of you.

Writing Style

The first question that many students have that relate to writing a science fair project report is if it is okay to write in the first person. Students cannot write in the first person when writing a science fair project report. The entire report needs to be written in third person. This can be tricky as students are discussing what they did and what they discovered.

In addition to writing the report in third person, students will also want to avoid creative tones in their writing. While students are encouraged to use similes, metaphors and other creative expressions in English class, these are generally not appropriate in science writing. Students want to keep things as simple and straight forward as possible. The key is to explain the situation with as few words as possible.

Clarity

Clarity is one of the characteristics that judges will be looking for when scoring your science fair project. They are going to evaluate how easy your report was to understand, how logical it progressed from data to conclusions and how organized the overall report was. The design of your display board and you presentation will also be judged for clarity.

Formatting Your Report

Formatting is very important when you start science writing. To start with you will want to select a 12 point font that is easy to read, like Times New Roman or Courier. Next you will want to double space your report and create a one inch all around margin. Finally, you will want to add a header that includes your project title and a page number.

The format of your science fair project report will also need to follow a common layout. Most reports will have the following sections in this order: (1) title page, (2) abstract, (3) introduction, (4) background research, (5) methodology (experiment), (6) data and data analysis, (7) discussion and conclusions and (8) bibliography. Each of these sections will be broken down into sub-sections. For example, the methodology section will include subheadings of supplies and experiment design while the introduction will contain information about the hypothesis, the reason for selecting the topic that was selected and definitions of terms used in the report.
