Network security vs cloud computing

Network Security vs Cloud Computing: Which One Should You Go For?


When it comes to safeguarding your online activities, you have two options - network security and cloud computing. The primary objective of both these processes is to ensure that your data is secure, your devices are protected, and your online presence is not compromised. However, the question is which one should you opt for?


Firstly, let's understand what network security is all about. It is the process of securing your devices and data using a variety of protocols such as firewalls, intrusion detection and prevention systems, and anti-virus software. Network security provides a secure environment for communication and data exchange within an organization's infrastructure.


On the other hand, cloud computing is a newer concept that involves storing and accessing data and applications over the internet. With cloud computing, you can access your data and applications from anywhere, provided you have an internet connection. It eliminates the need for physical hardware, thereby saving costs and providing scalability.


Now, answering the question of which one to opt for depends on your requirements. If your organization deals with a confidential client base, you might want to opt for network security as it provides an internal network that can't be easily accessed from the outside. Cloud computing, on the other hand, is ideal for companies that require frequent data access, have remotely located employees, or have low budgets for server maintenance.


Both network security and cloud computing have their own advantages and disadvantages. But, choosing the right one for your organization is the key. You need to weigh the pros and cons of each option and pick the one that best suits your business objectives.

Router QoS Settings: Because Sometimes Your Netflix Binge is More Important Than Your Kid's Homework


If you've ever experienced buffering during your favorite show, you know the pain of slow internet speeds. But fear not! Router Quality of Service (QoS) settings are here to save the day (and your Netflix binge).
QoS allows you to prioritize certain types of traffic on your network. In other words, you can make sure that important tasks like video streaming or gaming get the bandwidth they need before less important tasks like your kid's homework (sorry, kiddo).
Thankfully, setting up QoS is a breeze. First, head to your router's settings page (typically found at 192.168.1.1 or 192.168.0.1). From there, look for the QoS settings. This may be labeled as "Traffic Control," "Bandwidth Control," or simply "QoS."
Once you've found the settings, you'll want to enable QoS and set your priorities. Most routers will allow you to choose between high, medium, and low priority, but some models may allow for specific applications to be prioritized (like Netflix or Skype).
It's important to note that your overall internet speeds won't improve with QoS. Instead, this feature simply allows you to better utilize the bandwidth you have.
So go ahead, prioritize that Netflix binge over your kid's homework. They'll thank you (eventually).

LAN subnet mask

Understanding LAN Subnet Masks


If you're new to computer networking, then the term "LAN subnet mask" may sound confusing. But don't worry, it's not as complicated as it sounds. Essentially, a subnet mask is a 32-bit number that helps to identify which portion of an IP address represents the network ID, and which portion represents the host ID.
So, why is this important? Well, when devices are communicating with each other on a local area network (LAN), they need to know which devices are on the same network segment, and which devices are on a different segment. This is where subnet masks come in.
Let's say, for example, you have an IP address of 192.168.0.1. If your subnet mask is 255.255.255.0, this means that the first three octets (192.168.0.) represent the network ID, and the last octet (1) represents the host ID. All devices on the same network segment would have the same first three octets in their IP address, but different host IDs.
In contrast, if your subnet mask was 255.255.0.0, this would mean that the first two octets (192.168.) represent the network ID, and the last two octets (0.1) represent the host ID. This would allow for more devices to be on the same network segment.
Overall, subnet masks ensure that devices can communicate effectively on a LAN by identifying which devices are on the same network segment. So next time you come across the term "subnet mask", you'll know exactly what it means!

Wireless encryption

Wireless Encryption


Wireless technology has brought about tremendous benefits to our lives. However, there is a downside to this modern convenience. The fact is that wireless networks can be insecure and prone to hacking. The solution is wireless encryption.
Wireless encryption is the process of securing wireless communications by using advanced algorithms and keys to encode data in transit.
The importance of wireless encryption is evident when we consider the rise of cybercrime. Hackers can easily access wireless networks and steal personal information, business data, and financial documents without anyone noticing.
Wireless encryption works by creating a secure tunnel between the wireless device and the network router. This process encrypts the data, making it impossible to read for anyone outside the network. Wireless encryption also provides authentication, ensuring that only authorized devices can access the network.
There are many types of wireless encryption, including Wired Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA), and Wi-Fi Protected Access II (WPA2). WEP is the least secure and is no longer recommended. WPA2 is the most secure and is the standard used globally.
While wireless encryption cannot guarantee absolute security, it is a critical measure that everyone should take to protect themselves from cyber threats. Implementing wireless encryption is relatively easy and can be done by accessing the router's configuration settings.
In conclusion, wireless encryption is a vital aspect of wireless technology that cannot be ignored. As technology continues to evolve, so do the threats to our security and privacy. It is therefore imperative that we take wireless encryption seriously and protect ourselves and our data by using the latest and most secure encryption protocols available.

Ethernet repeater


Ethernet Repeater: Improve Your Network's Efficiency



Are you experiencing slow network connection and drops in connection quality? If so, it might be time to consider using an Ethernet repeater. This piece of equipment is designed to capture data packets and then amplify or regenerate them.
