Advantages and Disadvantages of VoIP
With VoIP, telephonic connections are established over IP networks. VoIP communications maintain a high sound quality level. Read on to learn about pros and cons of VoIP
Advantages of VoIP (Pros)
One of the biggest advantages of VoIP is that it is extremely economical in terms of the cost charged per call. The only cost charged to the user is of the communication system installed by the user. The higher range a system has, the more cost is charged for the installation process. VoIP provides options to make calls to another VoIP system as well to a normal telephone. However no cost is charged for making VoIP calls from one computer to the other. For the calls made from a computer to a phone, a nominal fee is charged by the VoIP service provider on monthly basis. A computer is not a necessary component in communication through VoIP. Instead of a computer, the user can use a VoIP phone which is very similar to a normal phone. A VoIP phone can be used at place where a satellite based or broadband internet connection is present.
Disadvantages of VoIP (Cons)
There are disadvantages of VoIP technology as well. The biggest disadvantage of VoIP that users experience is the sound quality and in most cases a lot of disturbance is experienced during the calls. However the sound quality does improve with a higher bandwidth and stronger internet connection. VoIP calls that are made from one computer to the other are not uniform in terms of quality. The quality of calls in this case depends on the application software and the internet connection. VoIP phones do not work without electricity and this can be described as a big negative factor. Phones are supposed to be totally independent of electrical power. Hence in this case, the traditional phone has a higher preference rate than a VoIP phone.

Before a constructed building is completed, it is very important to test the quality level. For instance in a construction project, raw materials carry a very high level of importance. Nowadays, the quality level of these raw materials can be checked though automated methods. For instance in case of steel, the exact percentage of iron contained in it can be evaluated. These checks ensure a higher level of quality in the constructed product.
Calculated Project Management
Construction companies design a logical time line and feasibility layout according to the size and scalability of the project. In this way, they have a complete idea of the duration and human skill to be spent on each stage. Certain construction companies have their customized applications that assist in calculated project management according.

Controlled Website Access
A firewall prevents the browser from opening the websites which can transfer malicious contents into the system. A user can set his preferences and customize the system firewall according to his requirements. For instance, if all the computer users in a house are above 18 then the list of accessed websites will be of a certain nature. However in a situation where children are using the computer, a greater number of websites will be blocked.
Pop Up Blockage
When we open a website, pop ups are the biggest source of irritation. They promote various products and online schemes. Some times several pop ups open with a single click and the required webpage gets hidden. Pop ups are also a source of transferring viruses. However with the help of a firewall, all the pop ups can be disabled. As a result, pop up windows do not appear.
