Learn How VPN Works And The Different Types Of Vpns

Virtual Private Network or simply VPN is the program that creates encrypted and secure connection over a less secure network like the public internet services. It uses the tunnelling protocols in order to encrypt the data at the sending end and again decrypt the data at the receiver’s end. In order to offer the added security, the receiving and originating networks are required to be encrypted in Top 10 Ranked VPNs for the year (2020). VPN is common used today to offer the remote corporate employees, freelance workers and business trawlers with the access to the software apps that are hosted on selected proprietary networks. It allows them to gain access to restricted or protected resources and for this the users are required to be authorized to use the VPN apps. VPN Apps are widely used today by individuals, especially those who want to safeguard the data transmissions on mobile or websites that are restricted geographically.

How Does VPN Works?

At the basic level, the VPN tunnelling works to create the point to point connection which can’t be used or assessed by unauthorized individuals. In order to create the tunnel the end device needs to be operated on the VPN client at local level or in cloud. The VPN client that is running at the background is usually not noticeable to the end users until any performance issue occurs.

There are many factors affecting the performance of the VPN, of which the most common is the user’s internet connectivity, the type of encryption the VPN is using and the types of protocols ISP is using. In Enterprise, the performance quality can be impacted adversely by the poor quality of service which is beyond the control IT department of the company.

There are different types of VPN protocols which ensure to deliver optimal level of security to the systems connected to it when the underlying network is unable to provide the required security. You will come across with different protocols which are being used today to encrypt and secure the corporate and user data. Some of these protocols are:

  • SSL or Secure Sockets Layer and Transport Layer Security or TLS
  • IP Security or IPsec
  • Layer 2 Tunnelling Protocol or L2TP
  • Point to Point Tunnelling Protocol or PPTP
  • OpenVPN

The Different Types of VPNs

Remote Access VPN – It is the VPN client that connects you to the VPN Gateway Server on the company’s network. For this the device needs to authenticate the identity prior to granting the access to its internal network resources. Remote Access VPN Client actually depend on either SSL or IP Security to secure its connection.

Site to Site - Site to Site VPN is the client that uses the gateway device to connect a network in one location to the network of another location. Here the end device needs no VPN client as the gateway controls the connection itself. It is connected over the internet using the IPsec. It is commonly used for those who use carrier MPLS clouds in place of public internet.

Mobile VPN – It is the VPN server which actually sits on the edges of the company network, thereby allowing the secure tunnelled access by the authorized and authenticated VPN clients. Here the Mobile VPN Tunnels are not actually linked to the physical IP addresses; instead it is tied to a logical IP address. The logical IP address actually sticks to mobile device regardless of where it is roaming.

Kroger Gives A Tough Competition to Amazon With Using Of Robots

Kroger, a retailing giant in the US and its largest supermarket chain, has revamped its policies, undertaken several initiatives, in an attempt to save itself in the aftermath of Amazon foraying into the Whole Food world. From renovating its stores to changing locations, buying a meal-kit company to selling off their convenience store business, Kroger GreatPeople.Me has gone a long way to save their dying future against upcoming giants. However, the biggest risk taken by them is partnering with a British online grocery business, Ocado Group Plc. In their partnership, they hope to build twenty fully automated grocery stores in the US to give Kroger a boost in the commercial sector.

While e-commerce has eased out the lives of people, bringing grocery items to online stores is not as easy. Some items have a short life and perish easily; some items need refrigeration, some need to be kept away from humidity while some need to be kept in the dark. As such, I am keeping track of the inventory is almost impossible. Every user orders different items and every delivery is different. And Amazon has successfully taken over this challenge.


Ocado specializes in digital grocery shopping. Recently, it has used a thousand robots in one of its stores that are capable of picking out the selected items and stacking them too. This has helped reduce the cost of manual labour. The robots are designed to perform only a specific task and are even programmed to identify what items should go together in the same packaging. For example, eggs will be packed separately, and cold storage items will be grouped in one and packed separately.

Ever since the inception of automated solutions, the turnover of Ocado has increased manifold. Partnering with Ocado will surely help Kroger gain an advantage in this age of the Internet and automation of things. Other supermarket giants like Walmart and Amazon have yet to implement automation at this level. Another feature that sets Ocado apart is the specialized delivery van where the shelves and racks have been made to efficiently cover every square inch of the space.

Benefits Of LaserJet Printers

Nowadays, it has become increasingly more difficult to get printers that can produce good quality images that are crystal clear. 

However, you can get a very good result if you use a Laser Jet printer to produce your works. However you might be wondering what exactly a Laser Jet printer is. 

To understand this, you must first come to terms with what Laser printing is. Laser printing can be simply defined as electrostatic digital printing that uncovers and showcases details faster than the conventional printer would. 

This is because it utilizes a laser beam that constantly passes over the area where the printing is occurring. It does this through the use of electronically charged drums. 

Laser Jet printers are usually available as monotone or colour printers. The colour versions use dry ink and toner. And Laser Printers have a better colour quality because they utilize two lasers. 

This makes the whole printing process faster and it also has the added advantage of adding a more intense finish to the work being printed. This sharpens the details and ensure that the graphics are of the best quality. 

Laser Jet Printers are also equipped with anti counterfeiting marks. However, this is not a hindrance in any way because the dots that will be produced on the page are so small that the naked eyes cannot see them. 

These dots are printed in yellow and this makes them even more invisible. These dots are not an addition to the image or graphics being printed. They do not add more detail to the work but rather, they depict a code that will reveal manufacturing details under the right lighting conditions. 

These printers vary according to the model you want to purchase. With some Laser Jet printers, you can print faster than regular printers would allow you. With regular printers, you can only print about forty two pages in a minute. 

This printer will be a perfect fit for small offices since it can be connected to different networks and thus, can be used by ten to thirty people. The printers are very portable and they are usually wireless. They connect to computers through WiFi. This negates the need for wires that will only clutter up the office. 

This makes the office a less hazardous place because there are no dangerous wires being passed through closed circuits installed in the walls, or just lying across the floor of the office or workstation. 

The Laser Jet printer also performs the conventional duties of most modern office machines. It can be used for scanning, faxing, printing, and duplicating documents. Although faxing is an option that is no longer popular in a lot of firms, it is still included by the manufacturers of this machine. 

The Laser jet printer does not consuming much energy during the process of printing files. And it also one of the fastest options for printing. Therefore, this printer is a marked improvement from the days of the large photocopying machines that are slow, and still add a strain to the electricity bill. 

It has adjustable settings that can be modified to either automatic or manual mode that allows you to print content on the sides of a page. This type of printing is called duplex printing and it comes in handy when you have a lot of copies to print or if you are trying to avoid using up too much paper. 

However, this mode of printing is largely dependent on the model of the Laser Jet printer that you purchase. Therefore when you are shopping for your printer, you should pay special attention to this. 

If you ever have to print documents that contain a lot of graphical details, or involve a lot of words, Laser Jet Printers are your best bet. Office work would be much more difficult without the invention of these machines.  

Laser Jet printers combine the functions of three or more office machines and blend them into a portable workhouse that saves up on energy and time. So, tell me, if not Laser Jet printers, then what would you rather use? 



Tips For Finding The Right Laptop Battery 

One of the best parameters that users can use to evaluate a laptop’s overall efficiency is the strength of its battery. A laptop that will function well has to have a strong battery life and it must be able to stay mobile for a long time in addition to being power efficient. 

The fact that the usefulness of a laptop is dependent on its overall battery life cannot be overstated. Therefore, it is important for us to learn more about these batteries that power our laptops. 

For Notebooks, their batteries are usually composed of a combination of materials. They include Lithium Ion Batteries, NiMH (Nickel Metal Hyride), and NiCD (Nickel Cadmium).  

Of the three, Lithium Ion Batteries are usually the best. This is because: 

  • Lithium Ion batteries are usually made of compact and lightweight materials. This gives you the ability to utilize your device for optimum mobility. 
  • The batteries have a higher energy density. 
  • When compared to NiMH and NiCD materials, Lithium Ion, also known as Li Ion batteries do not experience memory effect. This is because they are only refilled according the quantity that is discharged during the last cycle. This often results in incomplete charging. 

Also, when these batteries are not fully discharged, they usually experience a drop in voltage. 

Although we have already established the fact that Li Ion batteries are very efficient, they are not so different from any other device used for power storage. This is because they also age. 

Because of this, the batteries have to be stored in under some preset storage conditions. This is done in order to extend the battery life and also to maximize the battery performance. 

These batteries are usually affected by high temperatures but cold weather conditions could also be equally harmful. Therefore, the batteries should be stored at room temperature. 

You should also know that the quality of the battery degrades constantly irrespective of whether you use it or not. This is because the electrodes are always being corroded by the ions. 

Therefore, if you are planning to store Lithium Ion batteries for a long time, you should ensure that they are adequately discharged at about 50%. Also, you should store the batteries at a moderate room temperature. 

If you would prefer to use your batteries regularly, you should discharge it from an electric socket and use it until it reaches a low percentage. 

A battery’s life depends on its life cycles. The life cycle is simple: the interval between a fully charged battery and the amount of time it takes before it is fully discharged. 

A battery is measured according to its capacity and this is represented by the symbol MAh which means Mega Ampere-Hour. For example, 2400MAh, 5000 MAh, 4400 MAh, and so on. It can also be represented as Watt-Hour. 

For us to get a better understanding of what the value of MAh translates to, let us use this simple formula: 

MAh= (Wh/volt) x 1000 

The higher this value becomes, the greater the battery’s energy storage capacity becomes. This also means that the battery becomes larger and heavier.  

Another factor that determines a battery’s size is the total number of cells that are in it.  

Cells can simply be explained as independent voltage devices. Their numbers are usually measured in a range that varies from 3 to 12. 

When purchasing a battery, you should always aim to get one that is original. Although maverick batteries can claim to give out the same output as original batteries, most times, they do not stand up to their claim. 

You can also opt for a used battery but you should ensure that the battery you get is not older than three years old. You can safely adjudge a battery’s age by its manufacturing date.
