Types of Network Switches

Types of Network Switches

Network switches are a useful piece of equipment to be included in a computer network consisting of several devices. There are some types of network switches that play a different role in network management. An important function is the ability to direct traffic and ensure that data packets sent over the network reach the desired location. By installing the appropriate set of switches, it is possible to run a system without depleting the resources and to ensure that the connected devices are operating effectively.

There are a total of four network switches that include the managed, intelligent, managed, and unmanaged enterprise. Different types have their own advantages and disadvantages, so it is important to use the right components to create the most efficient and economical effective system.

Here is a summary of the different types of network switches:


The unmanaged type is the most profitable in the market and a popular choice for home or small business established. One of its main functions is to help manage the type of data traveling between two or more computers and a shared printer. It rarely has to be seen or configured and is extremely easy to implement.


This type is more advanced and comes with an integrated software or user interface to allow the necessary adjustments to improve the functionality of the network. This system is the most used by the efficient network administrator because they are much more complicated to use and it is important to configure with suitable parameters.

The establishment of a fast network at incredible technology Li-Fi

The century in which we live has seen some of the most amazing and sensational changes when it comes to technology. To a layman, this progress may seem very difficult to understand. This does not come as a wonder because with all the inventions in the field of technology, it has become difficult to calm. However, the purpose behind this is to rapidly improve the user experience and improve their lives every day. The talk of the town recently made the startling Li-Fi technology. Although many people are not even aware there was a growing curiosity to know its application and benefits for a normal user. If it will grow to become as popular as Wi-Fi is still a matter of speculation. However, it is certainly a big step in the right direction and have a great influence if executed properly. To move a step forward in technology, we will learn about the Li-Fi technology.

What is it?

For many, this is still a big question mark. The most common explanation you will find is that this technology is claimed to be several times faster than Wi-Fi. In other words, Li-Fi technology is the optical wireless technology. Which makes it very special is that for data transmission, the light emitting body is used, commonly called LEDs. Li-Fi will use the quiet similar to what makes their homes and offices LED. For optical data, a chip used to operate correctly. Data through this technology are transmitted via LED bulbs and receive photoreceptor.

6 essential foundations of Time Protocol Network What you should know

Network Time Protocol Definition

The simplest definition of Network Time Protocol is that it is a network protocol mainly used to synchronize computer clocks. However, it can also be used to synchronize a myriad of other devices.

The 6 “need to know” Network Time Protocol are:

1. First, NTP requires a “reference clock” that defines the “real” time to run correctly. All computer clocks are synchronized based on the “real” time provided by the reference clocks.

2. No matter where you are in the world, Network Time Protocol uses UTC as the benchmark for the delivery period.

3. NTP automatically find the real source of time between several options and synchronize the best result. NTP is ultimately a fault tolerant protocol.

4. NTP is very accessible. A synchronization network is able to present many reference clocks. Each node in the network can exchange information bi-time (both directions) or unidirectional (one direction). Propagation time from one node to another creates a hierarchical system, on top of which are the reference clocks.

Wide Area Network (WAN)

Types and characteristics of WANs

What is a WAN?

There are two dominant definitions of a wide area network (WAN). The accounting definition of a WAN is a network that covers large geographic areas, usually for interconnecting multiple local area networks (LAN). The definition of a WAN is a network through a public network or a commercial airline, with a multiple WAN technologies

What are its main components?

The main components are WAN routers, switches and modems. These elements are described below in the hardware section.

CPE – devices in the customer premises are called customer premises equipment (CPE).
The customer owns or leases the CPE CPE service provider. A copper wire or optical fiber connects the CPE to the nearest central service provider or office. This bond is often called the local loop or “last mile”.

DTE / DCE – Devices that put data in the local loop are called circuit-terminating equipment or data communications equipment (DCE). Customer devices that pass data to the DCE are called data terminal equipment (DTE). The DCE primarily provides an interface to the DTE in the communication link to the WAN cloud.


In a WAN, you need different types of hardware components to function. Typical elements of the equipment you need in a WAN are:

Router – An electronic device that connects a local area network (LAN) to a network (WAN) and handles the task of routing messages between the two networks. Operates at Layer 3, and makes decisions with IP addresses.

Switch – The switch is a network device that selects a path or circuit for sending a data unit to its next destination. Operates at Layer 2 and use MAC addresses to send the data to correct destination.

Best wireless router: 6 strategies on how to choose the best for your network

If you have multiple devices, such as desktop computers, laptop and printer and want to create a network, then you need a router. And to avoid having so many wires connected to these devices, especially from one room to another, you need a wireless router. So how do you choose the best device for your wireless router network?

1. First, the router has been selected to be compatible (working) with existing wireless cable or DSL modem, you can use. Many laptops are sometimes equipped with a wireless card that is integrated, but some, especially the elderly. All desktop computers have a wireless card, either. Therefore, you may need to buy one. If you have an Apple Mac desktop or notebook, it is likely that the wireless card is integrated. And any other device to be shared on the network, a printer must be compatible, too.

2. To avoid security problems, even with the best wireless router device on the market, the password protection is recommended. Also, password protection repels pests from accessing your wireless connection, because you can not tell how far the signal reaches.

3. Some routers come with more than one antenna that allows them to be pointing in different directions, therefore, the wide area of ??coverage is another important factor when choosing a network router. For example, the coverage will include one or two rooms, high or low?
