Internet Services
|
Internet service is delivered through a various number of mediums. They include DSL lines, Fiber optic lines, Cable lines (coax cables), Wireless Internet signals and Satellite Internet signals. The speed limits per medium of Internet service delivery does vary. Wired Internet service mediums of transmission are faster in terms of speed than wireless mediums of transmission of Internet service. In general, wireless means of accessing the Internet from Internet Service Providers (ISPs) are used when access to wired lines from the point of access to the Internet are not in reach. That is to the ISP of choice to get Internet service from. In rural areas, wireless Internet service may be required where there is no wired Internet lines infrastructure. However, as more and more people need the Internet for more daily tasks than before, wired Internet access is becoming more and more available in rural areas. Fiber Internet is the leading type of Internet service in demand, these days. It is also the fastest Internet service possible when delivered to the premises of the customer.
DSL Internet
DSL Internet is Internet access provided over traditional telephone lines or fiber optic lines. There are two forms of DSL connectivity. They are wet loop DSL and dry loop DSL. Dry loop DSL is a lot more common than wet loop DSL, these days. A wet loop is a connection that shares the signal between 2 channels. One is for the telephone service and the other one is for the DSL Internet signal. A dry loop is a dedicated line for Internet signal access. With a dry loop, the telephone service must come over the Internet. From the router, a wired connection or Wifi connection to the user devices on the network can be made. Below, is the flow of a DSL connection from the Internet Service Provider (ISP) to the subscriber or end-user.

Cable Internet
Cable Internet is Internet access through coax cables. Cable Internet routers are required to connect to coax cable lines. Ethernet and Wifi connectivity to endpoint user devices can be made from the router. Bandwidth is shared with television signals. Also, bandwidth is shared with other cable Internet and television users. This could have some implications on Internet speed. During peak usage hours, a reduction in Internet speed may be present. However, speed reductions should not be significant when bandwidth is shared. The backbone of Cable Internet is the same as the fiber optic backbone of Fiber and DSL Internet services. In general, coax cable lines can transmit data at speeds greater than 50 MBps from the ISP. Upload speeds can be greater than 10 MBps, too.

FTTP or FTTH FTTP or Fiber-to-the-Premises is a direct fiber-optic line servicing of network and Internet connectivity to the premisis of the user. In residential areas, it is also known as FTTH or Fiber-to-the-Home. This type of connection for Internet service from an ISP is more faster, reliable and secure from the ISP. FTTP Internet connections can also carry more bandwidth than DSL or Cable lines can carry, too. Currently, in many places, DSL infrastructure is being replaced with FTTP infrastructure. This is being done to better serve the needs of Internet users. That is in terms of speed. As more and more tasks are being done online, greater quantities of bandwidth are being demanded by users. |
Wireless
Wireless Internet comes in a number of forms. They include the following.
A number of various different technologies are utilized to enable wireless Internet connectivity. These technologies include the ones listed below.

In home networks, wireless connectivity to endpoint devices is commonly used. This is known as Wi-Fi. It is easier to set up than Ethernet wired connections and is cheaper, too. Wi-Fi connectivity is also best suited for the need to be able to connect to the Internet in a mobile computing environment. However, this is beyond the demarcation point. That is the point where the ISP’s line to the premises ends. Wi-Fi is provided by the modem or router connected to the demarcation point. Multiple user devices can connect to a given router at the same time. This is very true for Wi-Fi connectivity. However, for Ethernet connections which are wired, the number of wired connections that can be made directly from the router or modem depends on the number of Ethernet ports there are present to be connected to. It is important to note, the Ethernet port to the demarcatioon point is excluded from the number of user-device Ethernet ports when it comes to the number of Ethernet ports devices can be connected to.
Types of Wi-Fi Access
Wi-Fi access can be private or open. Private Wi-Fi is password-protected. Open or public Wi-Fi is not password protected. Wi-Fi that does not require a password is not as secure as private Wi-Fi. That is one thing which one needs to be aware of when using public Wi-Fi. Following best practices while using the Internet in public areas can help one limit potential security risks to personal information and even their given online device. In general, in any type of Wi-Fi network, having saved sign-in information like usernames and passwords is not advised when it comes to browsers. Also, it is best to keep all user accounts signed out when they are not being used. Less chances of hacking attacks occurring is an outcome of these steps being taken.
