Optical fiber
The main advantage is obvious, speed. An ADSL connection offers a maximum speed of up to 20 megabytes. It is very important to highlight the "up to", since the speed of an ADSL connection depends a lot on the distance from the plant to our home. If we live more than a kilometer from the central, the speed that will reach us will be much lower than those 20 megabytes. On the other hand, when using copper cable, ADSL is more prone to failures or loss of quality of service. The fiber optic cable, on the other hand, is made of fiberglass and is specially designed to transmit large amounts of information. In addition, this type of cable does not suffer interference problems nor does it affect the distance of the control panel. That is, the fiber either goes or does not go (always talking about FTTH). Do we really need such a high speed internet? It is a really difficult question to answer. The answer is: it depends. It depends on the use that we are going to give to our internet connection. Being honest, most users will have enough with a properly functioning ADSL connection. To surf the web, read the mail and visit our social networks we do not need a high speed connection. If we want to watch movies or series in streaming we will need more speed, although I can tell you that I personally use a rural connection of up to 10 megabytes and I watch Netflix in HD without any breaks or stoppages. The online game is more demanding and if we are many at home and we all connect at the same time, the ADSL could fall short.Now a days many cable internet companies are available in the market. Finally, it is necessary to comment that the internet speed does not depend exclusively on our operator. We have to have some equipment ready. A rough way, if we hire a connection of more than 100 megabytes and we have a network card that is not gigabit, we will never obtain the maximum speed contracted. We must also assume that WiFi is very complicated to get all the speed contracted, as it depends on many external factors not controllable. In the article "Is it worth installing 300 mega fiber?" We tell you what factors we must take into account to get the most out of our Internet connection.

A contract protects your interests in different ways, assures you that you will receive adequate compensation, on time and if there are changes in the requirements once the project is started, modifications must be made, where the new estimates will be specified.
Below, we will give some tips that you should keep in mind when preparing the contracts that will set your services and the type of relationship you will establish with customers. Maintain a written contract For more confidence that you have the person who will act as a client, we must always maintain a written contract( Contingent Employment ), as this will be the only thing that officially supports all that was agreed. If we simply reach verbal agreements, in case there is a legal problem, those agreements will not help us. Even the use of emails can not be considered a legal backup. You should always have a written contract, which summarizes in your paragraphs, the work that you as a designer are going to do, the conditions on which the business is established between you and the client, and some other legal details that could Serve in case of any conflict. We know that this may sound boring at first, but it will end up saving you a lot of problems. A written contract with signatures of agreement provided by both parties, is the best legal document that can be counted. Although today, media and communications have facilitated the creation of contracts with customers over long distances, for some institutions in certain countries contracts made with electronic signatures do not represent the same legal level as a physical contract, written and signed in person. If you do not know how to start making a contract, you can look for examples on the Internet or even download a template that allows you to get an idea of the basics of your contract. If necessary, you can go to a society or association that provides legal services and advice in this field, and if you have extra money, you can consult a lawyer exclusively for this. Do not give up the rights to your work before time One of the most common errors that arise when making contracts, is not to establish a text that indicates that everything prepared by the designer or developer will be assigned to the client once the first one has received his payment in a complete manner. To ensure that our contract covers this issue and prevents difficult situations of rights, we must include a phrase that specifies that only after the services are completed and once the payment has been received in full, will the rights of the application or design to the client who requested it. These intellectual property rights include the use of the product, the ability to make modifications and reproduce it, the delivery of the designs and sketches made, the system or software developed, among other things. Make a good statement of work When we work a pre-made contract or with a template, it is not recommended to modify to a large extent the clauses that are already defined, however there is a section of special importance, which must be modified totally if necessary, all with In order to adapt to what we really want to obtain, this section is called "Work Statement". The work statement is a part of the contract where the agreement between the client and the service provider is defined bluntly. In it you can define the scope of the project to be carried out, that is, where the product will cover once finished, this is where we can specify if any kind of consulting service will be provided after delivery, and the parameters to determine if the The execution of the project was successful or not. We must establish certain key points to solidify this statement, in it we must explain the context of the project, the objectives, the tentative dates of delivery, the total term and the estimated cost. In this way the client will not have the opportunity to expand the scope of the project. By not establishing a good work statement, the client can consider the quote request as something official. Make your contract look professional Always seek to use a presentable contract, with good writing and format, which denotes your professionalism, relaxed if necessary but at the same time to understand that formality is necessary when dealing with legal issues. While your contract has all the essential elements, you are free to make improvements or redesign it in the way you want. At the end of the day, a contract you make will also represent your brand, so you can take an additional time to find the design that best suits what you are looking for. If we manage a contract that looks good and at the same time is professional, we will contribute to increase the trust in the client and this will increase the chances that he will choose us to work on his project. To achieve a good presentation, you can follow a series of recommendations, avoid using underlined texts, do not make too much use of italicized text, omit words completely in capitals, do not use sources of different colors or types, use wide margins, and in If it is a very broad contract, use numbers on the pages. Freelance contract model There are many references on the internet to download contract models for freelance jobs. Obviously, they are all guidelines, and the best option is to have a legal advisor in your country that can elaborate your contracts based on the laws that govern where you live. However, as a guide, we share some free models of contracts circulating on the Internet. You have a few freelance contract examples available to download, such as modelcontract.net, or info autonomos. conclusion Making a contract as a freelance can be a very intimidating topic, however it is very necessary to guarantee a healthy working relationship. Hopefully with this series of tips that we have given you, it is easier for you to draw up a contract and as such you can improve your way of working and contacting clients. The speed of the Internet has always been one of the main complaints of consumers. Telecommunications companies always promise a lot and sometimes they are not able to comply with the speed they offer in their ads. To make matters worse, there are services such as the famous television platforms that require a minimum bandwidth to operate.
To understand the advantages of fiber optic, we will quickly compare the different types of Internet connection, to understand which is better for us. ADSL It is a direct connection to the telephone exchange, which offers you Internet through the old copper cable. It is more difficult to hack, but its maximum speed is very limited (20Mb), it is subject to interferences that cause low speed and various problems, the quality of service varies greatly depending on the cables and the distance to the central. Cable The cable connection usually has a backbone fiber optic network, but the wiring to the user's location is carried out through the television coaxial cable. So the quality of the connection is limited to the slowest transmission medium, in this case the coaxial cable. Normally the bandwidth is shared among users in the same area using the same wiring. If there is little demand there is no problem, but if it is saturated in a certain building or street, they can produce slowdowns. It is also an easier system to hack using sniffing techniques. Optical fiber This system is the most modern of all, and is based on the transmission of light through a cable. It does not need so many repeaters, because it can work without them in distances of 2 to 70 kilometers. With laser amplifiers it can reach 150 kilometers. This technology does not suffer interferences caused by changes in voltage, temperature, or other cables, nor losses depending on the distance to the central, as occurs with the ADSL. Mobile connections Here the connections to the Internet of smartphones are grouped, via satellite or antenna: 2G, 3G, 4G, etc. Although they can be used at home or on a desktop computer, they are expensive and have a very low download limit, so they should only be used for what they are: connections for mobile devices. Advantages of the optical fiber on the cable Fiber optic networks are increasingly used thanks to the advantages offered in terms of data transmission speed. But, if we are going to make an investment, it is fair that we first know what benefits we can obtain to decide if it suits us or not. Why do you need more speed in your company? What are the advantages of fiber optics? High Speed Data Transmission The transmission of data by fiber optics is much faster. If in a normal system we can reach a maximum speed of just 100Mb / s, in an optical fiber has traditionally reached 10Gb / s each time new formulas to multiply its speed up to several terabytes. Apart from the actual speed, cable internet companies this implies a faster Internet connection, a download of large files in a few minutes, the possibility of making an online backup without consuming too much bandwidth, etc. Better bandwidth With the bandwidth we refer to the amount of information that can be sent in the same unit of time. If you connect many computers at the same time to a wireless network or cable network, you would get much lower speed for each, while with the fiber you could connect more computers without seeing your options limited. Avoid interference Unlike wireless networks, which are quite vulnerable to common activities such as turning on a microwave or going up in an elevator, fiber-optic networks avoid electromagnetic interference, which will avoid problems of speed reduction, connection interruptions, conversation crossings phone, etc. Better Video and Sound quality If your company wants to make videoconferences in real time, fiber optics allow you to improve the quality of video and sound formats so that your telephone conversations and recordings can be seen without interference, cuts, and excellent image quality. More security Surely you already know the security dangers in a wireless network. In a fiber optic the intruder is detected very easily, so that stealing or intervening in data transmissions is not easy. From the point of view of the user, fiber optic brings many improvements with respect to ADSL or cable. Its main virtue is that it always maintains a constant speed, because as we have said, it does not suffer interference nor does it affect the distance to the central one. And always reaches the maximum of the contracted speed. Not like ADSL, which rarely reaches 70% or 90% of the speed you pay. Fiber optics offers better results in tasks that require intensive data transmission, such as backups or transmissions. Many times we fill our mouths talking about the advantages of working on your own, being your own boss, not depending on anyone, and being able to make our own decisions in all professional fields. But we do not always clearly identify what these advantages are, do we see them?
First of all, it is worth mentioning that talking about the advantages of being self-employed or entrepreneur should go hand in hand with talking about the disadvantages or risks that this entails. But today I want to focus on the Contingent Employment positive vision of being professionally dependent on ourselves, and thus speaking only of the associated advantages. Without detriment, of course, to allow me to mention that the risks (which are not disadvantages, as I do not see them) that may exist, are well worth taking into consideration the considerations that are obtained. Obviously we could go into a thousand and one details, in a thousand and one reasons to be autonomous or entrepreneurs, but I personally believe that there are a few key factors: self-realization, quality of life and economic. And probably in that order. Possibly in my opinion the main reason, the main advantage that brings to be autonomous or entrepreneur is self-realization, satisfaction with ourselves and the freedom that gives us not to depend on anyone, that and no other is for me the main asset, the Main reason not to work for anyone but for oneself. I very sincerely say that if today I made a great offer of a company of course you always hear, it is a fallacy to say that you give up millionaire offers for being "free", but I have no doubt that at the time of taking the decision would have many other factors besides the economic one. And for me to be an independent professional and direct my business is priceless, and my main idea would be to reject the proposal. Of course some will say that such a position can only be maintained because you earn a good life on your own, of course, I do not deny that I can be well paid in my own business, but this is not an obstacle, to love freedom (Yes, with the portfolio very close in the ranking, because I believe that professional freedom goes hand in hand with filling more and better the portfolio) above all. And is that the quality of life and income are the logical consequence of self-realization. Obviously the very nature of self-employment allows us to improve our quality of life (we make sacrifices, but at least we do it for ourselves), and of course, usually as entrepreneurs or self-employed we earn more than salaried employees (we also have greater risks), but I reiterate in this case (and maybe it's in a few things in life that says so) it's not just money. It's money, but there are also many of us who would not change our free professional career, for the attachment of a company or office easily. What is fiber optics and how does it work?
In our dissertation of what optical fiber is, we have to talk about light traveling through a suitable cable, bouncing repeatedly against walls. Each of the small photons (light particles) jumps down the tube like a sled going down an ice rink. Now you could expect a beam of light, which travels in a transparent glass tube that can simply get out of the edges. But if the light strikes the glass at a very low angle (less than 42 degrees), it reflects back again, as if the glass were really a mirror. This phenomenon is called total internal reflection. It is one of the things that keeps the light inside the tube. The other thing that prevents the light from coming out of the pipe is the structure of the cable, which is made up of two separate parts. The cable internet companies main part of the cable in the middle is called the core and that is the part through which the light travels. Wrapped around the outside of the core is another layer of glass called the coating. The work of the coating is to keep the light signals inside the core. You can do this because it is made of a different type of crystal. (More technically, the coating has a lower (refractive index). Types of fiber optic cables Optical fibers carry light signals down in what are called modes. That sounds technical, but it only means different ways of traveling: a way is nothing more than the path that follows a beam of light through fiber. One way is to go directly through the center of the fiber. Another is to bounce off the fiber at a small angle. Other modes involve bouncing by the fiber at other angles, more or less pronounced. In order to send this data, it is necessary to fragment it into small fractions, which is called "Packet Switching". Thanks to this, data is prevented from overlapping, counting each of these packages with specific information that will allow the package itself to know where it has to go, that is, to which computers they must access. All about Ethernet One of the main problems that took place before the appearance of the CSMA / CD, was precisely that sometimes several teams sent packets at the same time, which caused a collision between the data that affected the transmission. However, thanks to this protocol, before sending the packets, the devices contact the network to find out if they are free to carry out the transmission, so that, if this is the case, send them to the data or, on the contrary, it will wait for it to be released to make the shipment. Thanks to this, the data arrives in perfect condition and there is no collision between them at any time cable internet companies,which guarantees a much more fluid operation and above all ensures that the data will always remain in perfect condition. Advantages of Ethernet versus Wi-Fi Possibly at this point you are considering the differences between Ethernet connections and Wi-Fi connections. Basically, an Ethernet connection is a Network connection via cable, while a Wi-Fi connection is a Network collection wirelessly. It should be noted that we should not be confused, that is, we can establish Wi-Fi connections between our computers, usually through a router, but the main difference is that we use Ethernet with the idea of connecting several computers within a private or internal network. the company itself or housing, while Wi-Fi and is generally used for internet connection. That is, we can use both types of connection in any case, but each of them for a different type of connection. However, the objective of both is to exchange data between computers, but, as we mentioned at the beginning of this section, they do it differently, this connection being established wirelessly in the case of Wi-Fi and cable in the case of Ethernet Ethernet vs. Wifi The main difference between Wi-Fi and Ethernet is the speed of the connection and the reliability, since the wireless system can be very convenient since it avoids the use of cables, but also considerably slows down the connection, while with an Ethernet connection, as long as we have a cable of the appropriate category based on the maximum connection speed that we have, it will allow us to take advantage of all the speed and distribute it adequately among all the connected equipment. That is, with Ethernet we will transfer information more quickly and with greater reliability than with Wi-Fi, while with Wi-Fi we will have more convenience to establish the connection, avoiding the use of cables between the equipment. We remind you that we can also use an Ethernet cable to connect the router or modem to our computer, but this would also be part of the internal connection of the office, that is, with this cable what we do is connect our computer equipment to the peripheral that is responsible for providing internet, but it would not be a connection to the Internet itself. As a detail, it is important to take into account not only the category of the cable, that is, depending on the speed at which we want to transmit the data, we must choose one type of cable or another, so that at present, the categories Most common are Cat. 5, Cat. 5e, Cat 6 and Cat 6a, allowing maximum connections of 100, 1000, 1000 and 10000 Mb / s respectively, achieving greater effectiveness of the connection as we increase the category and in relation to the distance of the connection. If you want to know more and read other articles similar to Ethernet: what is it, what is it for, we suggest you visit the Internet category. We present you with some tips so that you can carry out an independent career in a successful and professional way. Take note!
Some people choose to work in a freelance way to develop their skills, strengthen their networks of contacts, earn more money, escape from the corporate routine and / or have more work flexibility. Many times becoming an independent professional can cause some fear because you do not know where to start, how to find clients or how much to charge, for example. Whether you chose to be a freelance worker or you just became one of them, here are 9 tips to help you develop an independent career successfully. Create a network of contacts Start by telling the people closest to you what you are doing and making it clear that you are available to help those who need it. Little by little, tell the most distant people as well. Make new connections It is important to meet independent workers who can advise or support you in any situation. Besides being "the competition", they can be a great source of information. Search through networks such as LinkedIn and attend conferences and meetings that take place in the area you work. In today's world it is almost unthinkable to think that one can work in isolation. When youContingent Employment consider that you are a bit more stable, a good idea can be to rent an office in a coworking space. Set a fee Your network of contacts can help you determine how much to charge for your work. You can ask your fellow independent workers for market rates to determine yours. Do not make the mistake of collecting what you need to cover your expenses. It is good that at first you put a low price to your work while you are looking for clients and you experience the time of work that some things take you, but sooner or later you will have to increase it. Find a good accountant To manage your taxes, whether your pension contributions, earnings, etc., it is always good to have a trusted accountant nearby to advise you. Worry about understanding legal issues It is always good to have someone to turn to if you need legal advice. One of the biggest difficulties that freelance workers have is the lack of payment. Therefore, it is advisable to make contracts with your customers every time you have orders. Have the documentation in order It is recommended that independent workers have personal cards, cv or a logo on hand to deliver to potential customers. It will also be necessary to set up a work contract to start a job and submit invoices for payment. Spread the word It will always be good to have LinkedIn, Facebook or an updated website profile, which makes it clear that you are looking for employment opportunities. In addition, it will be positive to converse with people at events or be active in online communities. Adjust the amount of jobs Freelancers sometimes make the mistake of accepting too much work. From the beginning, make sure you have a free space in your agenda that will be useful for you to have time to build your contact networks and advance in business development or train as a better professional. Do not be tempted to accept all jobs, especially when you are not able to do a certain task. It will always be better to see the rejection of a job and the sincerity of the worker about what he is qualified to do and what he can not. Be prepared for periods of drought Independent professionals have a variable income, so you always have to be prepared to go through periods with little or no salary income. We present you with some tips so that you can carry out an independent career in a successful and professional way. Take note!

The use of the Ethernet cable is again an alternative to overcome the interferences that reduce Internet access speed
One of the advantages of connecting to broadband Internet is the possibility of doing so through a wireless connection thanks to routers with the ability to create Wi-Fi networks in an area between 20 and 50 meters around this device. This means that cable companies must aggressively produce high-quality mobile apps that complement their television services. These networks provide greater comfort and flexibility in homes, since it is not necessary to make cable installations in the rooms. In addition, they allow different devices - computers, mobile phones, tablets or consoles - to connect to the network at the same time. However, in a Wi-Fi network there is a significant loss of speed with respect to the cable connection, not to mention security deficiencies. It must be borne in mind that the connection speed contracted to the Internet with a telecommunications operator (ISP) is the maximum available to the user. Therefore, in no case, the choice of cable or wifi as connection mode will make Internet access go faster. Under the Wi-Fi technology there are different standards that regulate the spectrum band of 2.4 gigahertz where they work, as well as the rest of the necessary parameters for their use. Standards, scope and interference The first standard used in domestic environments was 802.11b, with a maximum speed of 11 mbps. Then it has been passed to the following 802.11g and 802.11n, with a limit connection of 54 and 300 mbps. Each evolution has meant an improvement in the maximum, although not always real, access conditions. However, this speed is not always met, since different factors associated with the environment where the user is involved. This is due to interference with other devices that work in a range of the spectrum near the wifi, as well as the loss of signal motivated by the distance to the router or natural barriers such as walls and walls. For this reason, we are working on the development of a new standard, 802.11a, which works in the spectrum band of the five gigahertz. In this band there is not as much saturation as in the 2.4 gigahertz band, but on the other hand, its scope is much smaller. Therefore, it is indicated for specific uses. |
