Network Questions and Answers (Q&A)

Villi and microvilli are both found in the human body. The fact that the word 'villi' is present in the two words does not mean they are referring to the same thing. In fact, their functions in the body are different. Villi are like small projections from a mucous membrane, particularly those found in the intestines. Villi are very short in length; approximately, each villus is 1mn long. Inside villus, there exists microvillus.

Villi can also be called intestinal villi. The microvilli in them act only on the intestine lining by increasing the surface area so as to aid absorption. Microvilli, on the other hand, are generally found inside the various cells in the body; they are present inside the taste bud, and they are also functioning in the ear. The job of the microvilli is to increase the surface area of the cell, and as a result, they are aiding, absorption, adhesion, secretion, etc.

Two terms that usually surface in network protocols, computers, and file systems are the NFS and the CIFS. You may have encountered them once or twice when you are using your computer and have no idea what they are. Let us start with NFS. NFS stands for Network File System that is usually used in Unix or Linux-based operating systems and somehow related Microsoft’s Windows. This application is intended to have remote access in your computer.


The old files in the user’s computer can be edited and changed through another computer as its remote. On the other hand, CIFS, or Common Internet File System is used in Windows for file sharing. It always initiates a request when you want to access files on computer A through Computer B or the server PC. Computer B will only then respond to the request that the program made. This is the choice of big companies who have hundreds of employees that need to access or work on common data.

CCDA is the acronym for Cisco-Certified Design Associate, CCDP stands for Cisco-Certified Design Professional and CCDE is the acronym for Cisco-Certified Design Expert. These three terms refer to certification systems for individuals that are knowledgeable on Cisco products. Therefore, they are not the same. Cisco is the leader in networking technologies in our world today. These three Cisco certificates differ in their level complexity. It is expected that an individual starts with CCDA, then CCDP and finally progress to CCDE.

An individual with CCDA certificate is able to design a Cisco converged network. This person is expected to be able to design routed and switched network for business. CCDA is the basic level of comprehension of Cisco devices. An individual with CCDP is expected to be able to design and implement addressing and routing complex networks. After this is CCDE, a person with CCDE certificate is expected to be able to design large and advanced networks.

5G simply means Fifth Generation, and it refers to a super-fast wireless mobile network. We are currently leaving at a time when everybody wants to get things done very easily at a very faster rate. Before now, technologies have brought about the use of 2G, 3G, 4G, and now we are moving to 5G.

What this means is that people will be able to enjoy internet connection at a very faster rate because the internet speed will increase, and it can always be relied on. I think we all need to envisage a period where you easily get whatever you need on the internet or a technology that will put an end to the various problems we encounter when making transactions on the internet because of poor network.

However, this won't come cheap; people will definitely pay more for this service because it will also cost the network providers a lot before this technology can be achieved.

5G has already been launched, though it is limited presently. This means it is yet to be launched worldwide. However, the fifth-generation wireless mobile network is expected to be launched worldwide in 2020. As I said, some people are already enjoying the 5G network. 5G was first launched by Verizon in April.

This actually surprised so many technology companies and a lot of people as well. This achievement of Verizon has strengthened people's hope about the possibility of having the super speed network launched in all parts of the world by 2020. As a result of this development, some parts of Chicago are currently enjoying 5G. 5G is needed so that people can have a more robust internet experience.

5G simply means people will be able to get whatever they want on the internet at a very faster rate. This will also increase internet connection in most third world countries.

As the world is gradually moving to the next generation of wireless mobile networks, we need to ask ourselves about the various benefits it has over 4G. Just as how 4G came to support 3G, 5G is also coming to support 4G. Whenever 5G is mentioned, it is referring to a technology developed to compensate for the daily increase in data demand.

Since 5G is designed to give a super-fast internet connection, I think the major difference between both technologies is that 5G will be about 15 times faster than 4G. This is quite incredible, and it is going to change a lot of things if it is achieved.

5G is going to be faster than 4G because it will travel on super high radio frequencies. This will definitely give us unhindered access to the internet with fast speed. Also, it will also make internet connection and speed more reliable.

Local Area Network is otherwise known as LAN, whereas VLAN is the Virtual LAN. LAN is a local assembly of network devices which employ the communications between the connected devices. VLAN is a type of LAN which boosts the capabilities of a flat LAN. LAN works on a single broadcast domain while VLAN works on numerous broadcast domains.


VLAN can integrate the end station having similar requirements regardless of their physical location, which is not possible in the case of LAN. Basic LAN is restricted to its capabilities and causes clogging in the network. Virtual LAN can only be made using switches or bridges while in LAN hubs, switches and routers are used.

I think it is important to know that the fifth-generation wireless mobile network is not designed to render the 4G useless or obsolete. The 4G still works pretty fast in some parts of the world. In fact, the 4G network is going to stay longer even when the 5G network is launched across the world.

Technology companies are actively working on 5G, which is the next generation of wireless mobile networks in order to increase internet speed and connection so that your internet experience will happen at a very faster rate.

The coming of 5G wireless mobile network will also increase the speed of 4G. 5G is currently being used in some places in the United States of America, e.g., Chicago.

In April, Verizon became the first technology company to launch the fifth-generation wireless network. As much as different companies are working on creating the fifth-generation wireless network, the 4G will still be available for people to use.

No, you can't use a 5G connection on a 4G smartphone. 5G and 4G are not created with the same technology, so it will be practically impossible for the 5G network to work on a 4G smartphone. In other words, smartphones that use 4G LTE are designed in such a way that they are incompatible with the next generation of wireless mobile networks.

The technology is going to work perfectly on new phones that are designed to use 5G networks. The issue here is that 5G networks are yet to be rolled out to all parts of the world, so only a few people are using the technology.

But very soon, a lot of smartphones that support 5G networks will be made for people to buy. On the other hand, it is possible for a 5G smartphone to use the 4G network. The fact that you can easily switch to the 3G network even with a phone that uses 4G means you can equally use the 4G network on a 5G smartphone.

While it is possible for a phone that uses the 4G network to upgrade to 5G, it is advisable not to give it a try for now as the technology is still at the early stage of its development. To upgrade your smartphone to 5G is just a matter of installing software that will enable this. But 5G networks are yet to be rolled out to the masses.

Only those who can afford smartphones that support 5G networks are the ones enjoying the technology for now. For now, this upgrade is not possible because 5G is still very new, and a lot of updates and improvements will still be done on it.

For you to use the technology, you can either go for a new smartphone that supports it or by upgrading your smartphone to the kind that can accommodate both 5G and 4G networks. With this, you can start enjoying both the 4G and 5G networks.
