Everything You Need to Know about Router vs. Modem

While individuals, companies, and organizations should arguably have an Internet connection, the question remains: what’s the modem vs. router argument about? They’re actually both key components of a small computer network.

The router is linked to the modem, while the model is linked to the telecom’s DSL phone line or the cable company’s coaxial cable. When the Internet connection is via a satellite, the router is linked to a satellite modem. Here are some key facts about the issue:

Fact #1: The modem establishes and maintains a connection

The modem creates a connection with the Internet Service Provider (ISP) and then maintains it. It converts the signals between the router. The actual type of modem that connects to the ISP can differ. Some of the most common ones are:

External: This type of modem is located in a self-contained box that is outside a computer system. Usually external modems are little more expensive than internal modems are. Many experts also consider external modems to be superior to internal modems because they include lights that show how the device is functioning. Another key benefit is that they can easily be transferred between different computers.

Internal: This is a device that’s installed inside a desktop computer or laptop computer. The two types of internal modems are dial-up and WiFi. A dial-up connection is linked to a telephone line. Meanwhile, WiFi can connect wirelessly. However, the term “internal modem” usually refers to a dial-up modem, as technologies that followed them were referred to by different terms.

Business: As its name suggests, this type of modem is designed for businesses. While it’s designed for larger computer networks, the cost of installing and maintaining such modems are significantly higher than external modems and internal modems for individual CPUs.

Each type of modem has different features, advantages and disadvantages. It’s important to consider them before selecting one for a particular Internet connection.

Fact #2: A router forwards and tracks

The job of the router is to guide traffic going to the Internet, to the modem. At the same time, it prevents “internal” traffic from leaving the network. The internal traffic can be from computer to printer, computer to computer, etc. A router uses a series of numbers that’s been assigned to it, to track which computer made a particular request to the Internet, to send responses back exclusively to that computer.

Fact #3: A wireless router is common for homes and small businesses

It provides certain functions that make it practical for such applications. A wireless router can direct a network’s local data traffic, but a modem is required in order to connect to the Internet. Sometimes a cable Internet service or Digital Subscriber Line (DSL) provides pre-configured modems in order to link to the service. A wireless router can be connected to the modem to provide Internet access within the network.

To reduce the number of devices required when using a wireless router, one option is such routers that contain a built-in modem. The modem must be configured and then linked to an ISP.

4 Big Benefits of Wi-Fi Over Other Internet Connections

While the Internet has revolutionized our lives, the number of ways to connect to it is quite varied. They include Wi-Fi. Here are some of the key benefits related to using Wi-Fi compared to other methods of connecting to the net:

1. Cost-effectiveness

Connecting to the Internet via a wireless Wi-Fi connection is relatively inexpensive compared to wired connections. Besides the cost of installation being lower, the operating costs are also generally lower than wired connections. Both issues are in part related to the fact that Wi-Fi can easily connect with other users connected to Wi-Fi connections.

2. Wireless Communication

One of the key benefits of Wi-Fi over other types of Internet connections is its being wireless. Unlike several other methods of Internet access, Wi-Fi provides a continuous stream of communication for both business and personal applications. This differs from various other types of links to the Internet, which are much more intermittent. Wired Internet connections in particular tend to be much less reliable and continuous than Wi-Fi connections.

Another key benefit of a wireless connection is that the connection itself is more mobile. If you need to transfer your home or workplace, it’s much easier if you don’t have to deal with a spaghetti bundle of wires, which can take forever to untangle.

3. Productivity

More specifically, individuals, companies, and organizations that use Wi-Fi technology will be more productive than non-Wi-Fi users. That’s because they’ll generally have a steady connection to the Net, allowing their work to remain uninterrupted. On the other hand, those that use less reliable Internet connections, and wired connections in particular will spend much more time reconnecting to the net, and less time actually using it.

Productivity has always been critical in the workplace. But in the Information age it’s an entirely new ballgame. Staying competitive not only involves the traditional factors such as putting in the hours and producing quotas. It often involves maintaining a consistent link to the Internet. This stresses the importance of a Wi-Fi connection.

4. Accessibility

In particular, you can access Wi-Fi throughout the world. It doesn’t really matter whether you’re in a downtown or rural area. Unlike cellphones, Wi-Fi has a global standard. So you can connect to it virtually anywhere in the world with any Wi-Fi-compatible device. Even in relation to the Internet itself, the worldwide coverage of Wi-Fi is quite wide.

Accessibility has become of the most critical issues related to the Internet today, greatly due to the increased use of mobile devices such as smartphones and tablets. This highlights the importance of maintaining a continuous Internet connection when you’re on-the-go.

Internet connection problems are one thing when you’re at home or at the office. But it’s a worse situation when you’re elsewhere and have fewer sources of information.

Today, the ways of connecting to the internet can seem almost endless. Wi-Fi is definitely one of the most practical issues. It’s reliable. It’s accessible. It’s affordable. Arguably it’s one of the most effective means to connect to the Net.

Introduction to the deepness of the transport protocols…


The internet also needs to be measured to know how is evolving and performing, also one of the main reasons of internet monitoring is to have some kind of data to know its performance and how can be improved. All this data is collected and interpreted by professionals to know where and how the improvements should take place. Internet performance can also be simulated according to the parameters and data entered by the IT engineers, this helps to see and test different kinds of actions that the internet should perform.

Internet is also monitored by special computers and servers, this monitoring is a very important task in order to be able to forecast the internet performance and possible problems that might appear in the future.

All this data is stored in so called packet traces that can be used for many different purposes like the interpretation for the status and the resources of the network that is a very important part for traffic engineering and the dimension of the network.

The internet is based on data, all what we see in our screens is data it does not matter if are images, videos, numbers, etc…The more people that use the internet the bigger the network gets, the internet is growing at the speed of light, just imagine that in December 1995 the internet had 16 millions users and by 2014 there is an estimate of 2930 millions of users, that is 40% of the world population.

The grow of the internet will not stop, in fact that will be a catastrophe in todays world where all is done via internet, the goal is to continue and promote the development of the internet in order to make things easier.
