The types of Internet connection

Internet is part of everyday life of many people. It is a source of research for some, or leisure and work for others. The vast computer network expands at high speed, and it is impossible try to stop it. Such is the utility that is able to lend, which since the 60s, date of creation of Internet, until today, have developed various ways to connect to it through multiple media, trying each time to improve its performance and ease access, to bring it to mass audiences.

Nevertheless, this diversity of access methods Internet also brings with it still coexist many ways to access to Internet, many of which have been forgotten and unused for having been overtaken in terms of speed and capacity. This obviously lends itself to confusion, and that is why this article will find everything you need to understand which are the connection possibilities, how works each of the connections, and what are their main advantages and disadvantages.

Types of internet connections

Telephone line connection

Also called dial-up, is the oldest method of connection and was the only used when the Internet was in its infancy. Access is made by the user via a modem and telephone line. This type of connection is used less and less, since the data transmission capacity does not exceed 56 kbps, which makes navigation very slow. With the popularization of services of broadband access with affordable prices, the dial-up access is virtually extinct.

Besides of the low speed operation, dial-up connection is not stable and keeps busy telephone line when connected to the Internet. That is, or surfing the internet or talking on the phone. Regardless of the time at which you access the Internet, the telephone bill costs may increase considerably.

Types of internet connections

On the other hand, it is the simplest connection. It only takes one phone line available, a PC with modem, and an ISP free or payment. In the case of paid access, they offer different plans with limits of hours of navigation and access to limited or unlimited data. We must remember that the quality and stability of free access providers may be less than payment providers.

xDSL connection

The xDSL connection is provided through the conventional telephone network, but it is different to dial-up access. A modem converts this information into an electrical signal and separates it into a different frequency than that used by the voice, thus the data signal does not interfere with telephone use. This means that you can surf the Internet and use the phone at the same time. However, it is good to remember that it is necessary that the PC have an Ethernet network board.

The xDSL service operates by hiring an access provider, like dial-up, and you can access services with different speeds. For example, in the ADSL, the speed varies from 256 kbps to 8 Mbps; in ADSL2 or ADSL2 + ranging from 256 kbps up to 24 Mbps; in the VDSL you can reach a speed of 52 Mbps and up to 100 Mbps VDSL2. Despite the popularity of this type of access is not available everywhere.

The xDLS has the disadvantage that it is a shared service, navigation can be slower at peak times when many users use the service simultaneously.

Cable TV connection

The cable connection is increasingly popular and uses the same infrastructure as the service cable TV, which facilitates installation. Many cable television services offers in the package access to Internet with different speeds. In this case, data from the Internet and cable TV are transmitted through a single cable, then the signals are separated by a device called a splitter. From there we took a cable for TV and the other for Internet.

One of the advantages of this type of connection is that just simply connect the cable modem to the computer to be connected without the need to dial or activate a service. Please note that for this function, the PC Ethernet network card must be installed. Obviously, this type of access is possible only in regions where there are cable television services.

Types of internet connections

This type of access is available in different types of speeds. Browsing speed, and limit downloads and uploads data, depend exclusively on the package we have hired. Moreover, the speed is not affected by the number of users or the time of the day when the service is used. Unlike the xDSL access, the user will always have the same speed access at any time.

Satellite connection

Another alternative is satellite connection, for which specific teams that usually have a very high cost are required. You must purchase an antenna able to capture the satellite signal and transmit it to the computer with an internal or external modem receiver. In some cases, the antenna is provided by the service provider itself. This type of internet access, has plans that offer speeds ranging from 512 kbs to 2 Mbps.

Types of internet connections

One advantage of the satellite connection is that access is not dependent on the location. This way you will have access to internet anywhere where coverage comes. However, the more remote the place where we are, the stronger the signal.

Radio connection (Wireless)

Internet access radio is a way to extend a broadband connection somewhere where there are no service. That point can be anything from a small restricted area, such as an office, to a complete city. For that you need to configure a wireless network. Included in this mode, the Wi-Fi and Wi-Max.

One of the advantages of the radio connection is the possibility of sharing access and ensuring mobility to users. The basic infrastructure requires a delivery point internet service, which can be a wired, xDSL or satellite, modem compatible with the service, an Access Point (kind of radio) and computers with receiver or wireless network adapter for pick up the signal.

Types of internet connections

When sharing a high-capacity connection, users can split the costs, while the service guarantees a permanent and low cost of installation and maintenance connection. However, the simultaneous use for downloads may impair access.

Mobile telephone connections via 3G and 4G connections

The internet through cell phones is getting better. The arrival of 3G internet connection provided broadband cell phones with a previously unimaginable speed. However, the best, at least until today, is the appearance on the market of the 4G standard, which can receive and send data at speeds impossible to reach previously , giving us the ability to watch videos in HD quality listen to music directly from the cloud, among others.

Types of internet connections

Mobility is a major advantage of such services. For GSM networks, the transfer rate can reach 800 kbps. In the case of CDMA networks, the transfer can reach speeds up to 2 Mbps.

These numbers are largely superseded when our phone is compatible with 3G or 4G, which can far exceed these figures, reaching in the case of 3G to 2 Mbps, and in the case of 4G to 200 Mbps.

PLC (Power Line Communications)

Undoubtedly, the PLC technology (Power Line Communications) is one of the most interesting forms of connection that are mentioned in this article, because it uses power lines to transmit data at high speed.

Types of internet connections

Today is one of the alternative connection systems most used by users worldwide, as among many of the benefits it offers, is the possibility of using the electrical wiring in any home for exchanging data between nodes on a local network, with the convenience of not having to invest in the many meters of network cable necessary to mount it, something that appreciate many homes and small businesses.

Now it only remains to choose the connection mode to access the Internet and enjoy.

Differences between Hub, Switch and Routers

Hub, switch and routers are names related with the hardware devices that enable that computers to connect to a network. This article will explain what the basic differences between each of these devices, and how to know which one to use in a given scenario.

Routers switch hub

Hub

The hub is an electronic device that is required to interconnect computers on a local network. Its operation is simple compared to the switch and the router: hub receives data from a computer and transmits to others. When this data transfer is running, no other computer on the network can send signals or data. Just computers can send or receive data when all transmissions are completed.

In a hub you can have multiple ports, i.e. inputs to connect network cables for each computer. Generally, there hubs with 8, 16, 24 and 32 ports. The number varies according to the model and manufacturer of the device.

Routers switch hub

The best feature of these devices is that if one cable is disconnected or broken, the rest of the network continues to fulfill its task. Currently, the hubs are being replaced by the switches due to the small difference in cost between both devices, and most benefit from the switches.

Switch

The switch is similar in appearance to the hub, however presents a big difference: the data from the source computer are only sent to the target computer. This is because the switches create a kind of exclusive channel of communication between the source and destination.

Thus, the network is not limited to a single computer in the transmission of information. This increases network performance because communication is always available, except when two or more computers try to send data simultaneously to the same machine. This feature also reduces errors such as data packets collisions, for example. As well as the hub, a switch has multiple ports and number varies with the price and the manufacturer.

Routers switch hub

Routers

The router is a electronic device used in networks of larger size. It is smarter and capable than the switch, because, besides fulfilling the same function, also has the ability to choose the best route to a given data packet must take to reach its destination. It is as if the network was a big city and the router chooses the shortest and least congested route. Hence this name.

Basically there are two types of routers:

Static: This router type is cheaper and is focused on always choose the shortest path for data, regardless of whether the selected route is congested or not.

Dynamic: This type is more sophisticated (and consequently more expensive) as they are able to determine if there are bottlenecks in the network, and from this analysis send data even for a longer route, but faster, avoiding congestion.

Routers switch hub

Another interesting feature of dynamic routers is that they are capable to perform data compression to increase the transfer rate.

 

Routers are able to interconnect various networks, and generally work in conjunction with hubs and switches. Usually they have extra resources, such as firewall, for example.

For those who want to set up a small network, connecting, for example, three computers, use of switches is most recommended as the price of these devices are substantially equivalent to those of hubs. If you share broadband internet, a switch may provide more stable connection.

Routers switch hub

An important fact: when looking hubs, switches or routers, always choose known brands. That can prevent future problems.

The implementation of routers is generally used in company networks (corporate networks). Besides being more expensive, they are also more complex to be managed, and should only be used if there are many computers on the network.

However, many users with Internet access via ADSL manage their routers and modems to share the Internet connection with all computers on the network, without the computer has to be on, only the modem or router.
