Some Differences between Analog and Digital Circuits

Nowadays, technologies have developed well. Many great inventions have happened and these all bring betterment for people. Lives become much easier. Entertainment also can provide much better things. In this case, the great achievements and developments cannot be separated from the developments of the circuits used in each device. In some years ago, people and technicians still used the analog circuits. Nowadays, changes have brought developments so analog circuit has been replaced by the digital circuits. Of course, these two types of circuits have differences and those are nice things to see.

First point to see is about complexity. In this case, each person may have their own opinions. Some say that analog has more complexity, but there are also some people saying that digital circuits are more complex. In this case, analog circuits are like the work of art. Precisions are required since it is not only about the design of circuit, but it is also about the quality of components and accuracy in calculation. This is quite different from the digital circuits. Digital circuits are more about codes. Codes are used in order to operate and manage the circuits. Of course, things are operated from keyboards. From this aspect, then the analog circuits seem more complex and that is also the reason why people like the digital circuit.

Then, the next point is about the accuracy. It is true that the analog circuits requires great accuracy in calculations and constructing the circuits. Components must be placed and positioned well. Then, specifications of components must be calculated in high accuracy, so things must be in good accuracy. Then, the dialog circuits are more about the interaction of codes. This also requires accuracy, but most of the codes can be learnt in easier ways than the analog circuits. In this case, although those two circuits have complex differences, sometimes they are still required in specific condition. In this case, microchip.com can be the good source to know more about circuits, components and other things related to them.

Open Source Software

open source softwareIf you have ever used Ubuntu or Linux, you probably have some idea about open source software. Here are some examples along with a brief insight into the ‘what’s and ‘how’s of open source computer software applications.

There are three major types of software – Programming Software, Systems Software and Application Software. Of the three, the latter two come in two broad classifications – open source and closed source. There are many different types of application software which are open source and most of us regularly download and use them on our PC/laptop, such as VLC. In this Buzzle article, we will take a look at some popular and highly recommended open source software examples for different types of operating systems.

An open source computer software is either a systems software or an application software that is available freely in the form of source codes and the users are permitted, under the software license, to study, modify and improve the software. The Open Source Initiative has set certain parameters to determine whether a software license renders the software open source or not. These parameters are very specific and are as laid down below. In order to be considered Open Source, a software must qualify on all of these parameters.

Free Redistribution
The software license does not restrict anyone from selling or giving away the software as part of a software package which contains programs from various other sources. The license also should not require any royalty or fee for such sale or passing over of the software.

Source Code
The program should essentially contain source code and the distribution should be permitted in source code as well as compiled form. If the source code is not provided free, the means of obtaining it should be well publicized and should not cost more than a reasonable charge, though the preferred mode of obtaining such code should be free downloading via the Internet. Deliberate obfuscation of source code is not permitted and outputs of processors and translators are against the rule.
Derived Works
The software license must permit modifications to the source code and the distribution of such derived work must be allowed to be distributed under the same terms as the original software license.

Integrity of Author’s Source Code
Distribution of source code in modified form can be restricted by the license only if the license necessitates distribution of patch files with the source code for modification of the program at the time of writing it. In such case, the license must be explicit in allowing distribution of software which is developed from modified source code and may require derived works to be known by a different name or version number from the original.

No Discrimination of Persons or Groups
There should be no discrimination, whatsoever, by the license against any person or user group. What is made available to one must be made available to everyone else.
No Discrimination Against Fields of Endeavor
There should be no restriction on the use of the software for any field of work. If it is free for business use, it must also be free for use in lab researches.

Distribution of License
The rights to the program should apply to everyone, to whom the program is redistributed without any necessity for applying for additional license by such parties.

License Must Not be Specific to a Product
The rights attached to the program must not be specific to the software of which it is a part. Even if the program is extracted from that particular software package and used elsewhere within the program’s license terms, the user of such an isolated program would have the same rights as he would have had on using the program along with the original software distribution.

License Must Not Restrict Other Software
There should be no restriction on any other software that is distributed along with the licensed software. The other software may or may not be open sourced but that should not put any restrictions on their distribution on the same medium as the open source one.
License Must be Technology Neutral No part of the license should weigh upon any particular technology or interface style.

The biggest advantages of open source computer software are their ease to penetrate the market without the companies offering them requiring to sweat over promoting them and providing a sense of empowerment and flexibility to users and developers. The greatest disadvantages are argued to be their being in a perennially developmental stage and the ignorance of system testing and documentation. This point of concern may be true in case of very small software projects but holds no water for larger, more successful projects which risk no such negligence and their software are well-defined and subject to rules regarding testing of modifications and documentation. Before downloading though, get thoroughly informed about free software download pros and cons to be on the safer side if you are downloading software from some obscure site.

5 Internet Marketing Tips Small Business Owners Need to Know

Online corporate giants almost always intimidate small business owners who are starting a business online. After all, these corporate giants have the money, time, and professionals in order to make their website businesses profitable. Online marketing for business may cost thousands of dollars, and because of this discourages some small business owners to not follow through with the e-business strategies they have in mind.

However, most people don’t know that business internet marketing is not always costly- it just always has to be effective. For small business owners who want to figure out business marketing online by themselves, here are five internet marketing tips that can help you work on internet business marketing effectively and for FREE:

Why Spend When There are FREE Tools?
Inexperienced small business owners can easily be persuaded to purchase expensive internet marketing tools because of advertisements with “flowery” and promising words. Our advice to SMO’s is this: use Free Internet Marketing Tools to market your site, generate traffic, and learn the Internet Marketing process through experience. You may purchase professional Internet Marketing software only when you understand how it works, lest you want to waste money on a product whose potential you cannot maximize.

Work on Your Email Campaign
The email campaign is the most intimate and effective approach for internet marketing for business. Connect with people who are already interested in your products or services. In this way, your marketing efforts will pay off through direct sales that are most likely made from customers who have subscribed to updates from you (which means that they want your products and services).

Embrace Social Media Marketing
Connect with as many people as you can for FREE by using Facebook, Twitter, and any other social networking site. Signing up is free and it’s easy to find contacts (and prospective clients) by simply adding friends and regularly posting updates. The beauty of social media marketing is this: the network of contacts is virtually endless and it’s up to you to make your own network grow.

“Give in order to receive”
A clean method of internet marketing for small business is offering free eBooks and software downloads that can lure interested site visitors. Join forums and share your knowledge and expertise. Prove that you are a company with a genuine interest in your clients rather than merely being a money-making effort by a work-at-home individual.

Let YouTube Help Your Business
People have the tendency to watch videos over reading boring text, so make it a point to be active in YouTube and post related videos. This approach for internet marketing for local business is especially effective in reaching out to young audiences.
