Networking Basics – What You Need to Know about Networking

What is a Network Infrastructure?

A network infrastructure is a network or connection of all network devices with the internet and other such devices such as connectivity, management, Biz Ops and communication.

It is an interaction amidst the virtual devices of an organization such as systems and software through equipment like the routers, switches and more.

Network infrastructure allows for effective communication and service between users, applications, services, devices and so forth.

What are These Networks Used For?

Network infrastructures are mainly used for building a connection between users, applications, services, devices and so on. The purpose of a network infrastructure is to ensure the connectivity of all organizational devices to the internet as a main function.

Although network infrastructures are responsible for many more such functionalities however, the above mentioned is the most valuable one of all the rest. It is also the responsibility of a network infrastructure that no device shall be off the internet connectivity at any time, since that can cause the loss of tons of data for an IT giant.

Data storage is also a part of servers however, the same does not lie particularly in the domain of networking. The crucial role of networking infrastructure here is to secure and maintain that database.

In case of any misevent, network infrastructures must also be able to troubleshoot and fix the problems instantly.

What are These Networks Made of?

Network infrastructures are made up of following devices:

  1. Routers
  2. Switches
  3. Access Points
  4. Firewalls
  5. Servers
  6. Load-balancers
  7. Intrusion detection systems
  8. Domain name systems
  9. Storage area networks

What are Switches, Routers and Access Points?

A network switch is networking hardware that connects devices on a computer network by using packet switching to receive and forward data to the destination device. A network switch is a multiport network bridge that uses MAC addresses to forward data at the data link layer of the OSI model. 

A router receives and sends data on computer networks. Routers are sometimes confused with network hubs, modems, or network switches. However, routers can combine the functions of these components, and connect with these devices, to improve Internet access or help create business networks.

A wireless access point (WAP) is a networking device that allows wireless-capable devices to connect to a wired network. It is simpler and easier to install WAPs to connect all the computers or devices in your network than to use wires and cables.

Best Three Firewall Certifications That Can Make or Break Your Career

Best three network certifications that can make or break your career, including firewall.

Company infrastructures, data files and many secure information files are the most prized possession of any platform. The reason for the same is that data today is the most difficult thing to acquire. Acquiring data is difficult in today’s day and age. This becomes a driving force for unethical platforms and users to use unethical methods to acquire the data from other organizations. There can be multiple reasons for the same since it can include agendas such as competing in the industry or harming a nation and so on.

In order to protect that data, firewalls are used. Similar to how people build huge walls as their house boundaries, systems are protected with firewalls. These firewalls act as a safeguard to each and every aspect of their data. They ensure monitoring as well as tracking, which makes it easier for companies to retract the data as well, if lent out to any unreliable party.

As the data keeps increasing, the need for securing it also becomes a huge responsibility for organizations as well as nations. Firewalls therefore are the most important aspect of any organization’s cyber security. The things to understand is that knowledge about firewalls can make or break your career. Here’s how.

It Gives You Layers of Security

Firewall gives multiple layers of security to the organization and the systems as well. Firewall can either be physical or installed as a software. The physical protection automatically suggests laying of the hardware which means in direction that the data is not in contact with the outside world anyhow. However, since this is restrictive and can eliminate flexibility from the user’s routines, a soft firewall is important.

This entails that all information can be tracked and seen how and where it flows. The importance of this aspect is that it is an application method uses bits of code to determine the flow of the information. Such systems of firewall are known as Packet Filtering.

Internet Protocol Traffic is Accessible

Two types of Internet Protocol (IP) can be used: TCP – Transmission Control Protocol is connection based or UDP – User Datagram Protocol is connectionless. These protocols are the entry screening point for any information entering the system. This ensures that no unwanted and unnecessary item can enter the system. A firewall can effectively conduct stateful inspection which determines the right and relevant information and differentiates it from the clutter and threats.

Common Attack Vector

Hackers and attackers today do not stick to a single point of attack. Information from multiple directions is sent to the systems so as to overwhelm the system and make it utterly difficult for the users to identify the source of the information. The objective of a firewall’s common attack vector is to streamline that data of sources and identify the same. This safeguards the systems from attacks known as DDoS Attack.

These functionalities and support standpoints given by firewall as the stream of hope for any organization’s system. Let’s understand how you can upgrade yourself with Firewall through the 4 MOST IMPACTFUL & VALUABLE CERTIFICATIONS.

Cloud Computing & Data Science: A Collaboration to Know

Cloud computing and data science a collaboration you need to understand.

Big Data, Data Science, Machine Learning, Cloud Computing, Data Analytics, Artificial Intelligence – these are just a few of the newly emerged terms that have gained innate traction in the last few years. With the amount of change we saw happening in 2020 however, it is in fact important to understand the impact of Machine Learning and Cloud together on the world.

Understanding Data Science & Cloud Computing

Our digital world uses data as an anchor for survival with the Gen Z as their consumers. We understand Data Science as a method that uses the scientific approach to create, test and run algorithms so as to then mine data for machine learning and more.

Applications of Data Science

Weather Forecast

Machine Learning is extensively used for determining the weather forecast. It isn’t just the basic weather forecasting anymore but in fact, to predict the natural calamities going forward as well. Weather forecast has been in the process of getting conducted for a long time now however, with a ton of data getting collected today, the weather forecast can now in fact proceed for predicting calamities like landslides as well.

This technique right here works for both Big data as well as Applied Mathematics.

Media & Entertainment

The media and entertainment industry uses Big Data and Data Science for targeted advertisement, customer sentiment analysis, recommendation engines, an insight into customer church analysis.

HealthCare

The broader aspect says that the healthcare industry uses big data to save lives. It is extensively used in Medical Research, Personalized Treatment, Cost Reduction, Health of the Population and more. A great example of the same is United Healthcare.

Logistics

The process of transportation storage, loosely known as Logistics, surely uses Big Data for multiple things such as Flexible Routing, Capacity Planning, Smart Warehousing, Customer Satisfaction and more. The biggest example of this domain is the organization – UPS – Biggest Shipping Company across the globe.

Travel & Tourism

The industry of travel and tourism uses data science as well when it comes to Revenue Management, Market Research, Personalized Offers shared to the consumers and Investment Opportunities.

airbnb – a leading travel and tourism organization uses data science extensively as well.

Government & Law Enforcement

The New York Police Department, among many others, is known to use big data for Predictive Policing, Tracking Unemployment, Poverty and Improving Social and Economic Policies.

Data Science & Cloud Computing: Bridge the Gap

In a study conducted in 2019, the global giant, Walmart, was found to be collecting the data of its users and buyers at the rate of 2.5 PB data/hr.

This basically implies that on an average, 13.3 years of HD video data is compiled by Walmart EVERY HOUR! Besides, that’s equivalent to 130 years of HD Video data EVERY DAY!

Imagine the hassle that would go into saving this amount of data without having a cloud based server. That unfortunate scenario would in fact, burden our lives expectantly. The problems occurring in such a scenario could include the following:

Servers need storage space.
Servers need backup
For fast growing companies, server needs can be unpredictable.
With servers, companies can end up paying more than they actually need to.

With these many hassles, cloud is possibly the biggest blessing to ever exist for:

Data Scientists as well as Data Analysts.

In fact, companies may have to face additional problems such as the following:

Operating servers locally is a difficult task
Manual Intervention is needed
Single point of failure
Slow processing speed
Non-real time data

The Advantages of Cloud for Data Scientists

Data scientists use cloud computing for:

Testing Algorithms
Testing Hypothesis
Data Utilization
Cloud Creates a Level Playing Field


Importance of Cloud Computing

In the past years, Amazon Web Services, Microsoft Azure and Google Cloud Services have tried to increase their standing in this fast growing sector of the IT industry – the cloud computing domain since this is effectively taking over Machine learning as well.

These three giants now have a huge competitive advantage over the rest of the world however, it is still unclear as to who shall win this battle between the three.

The biggest advantage is that small and medium level organizations can also rely on these three cloud services because otherwise storing data would be extremely costly as well as inconvenient. Cloud has enabled the small level organizations as well to directly compete with the large organizations.

Your career can grow exponentially with:

Microsoft Azure
Amazon Web Services
