Troubleshooting Linux Made Simple: A Beginner's Guide Managing a Linux server or application can sometimes be tricky, especially when things go wrong. But don’t worry—troubleshooting in Linux doesn’t have to be hard! Here are some common problems and simple steps to help you fix them. Common Problems You May Face Web Server Issues           If your website is not showing up, check your server settings. Make sure your Apache or Nginx configurations are correct. Database Connection Problems           Many websites need a database to work. If your site isn’t connecting to the database, check if it's running and if the connection details are correct. Permissions and Ownership            Linux files need the right permissions to be accessed. Make sure your files have the right read, write, and execute permissions. Index Files Not Loading             If your web pa...

CPU vs GPU Understanding the Differences In this article, we will explore the differences between CPUs and GPUs in a simplified manner, discussing their functions, architecture, use cases, and how they complement each other. What is a  CPU? A CPU (Central Processing Unit) is the primary component of a computer responsible for executing all the necessary tasks required by the operating system and applications. Often referred to as the brain of the computer, the CPU works to complete tasks as quickly as possible, minimizing delays. What is a  GPU? A GPU (Graphics Processing Unit) was originally developed to render images on a screen. Like the CPU, the GPU contains ALUs, control units, and caches, but it differs in having many more cores—sometimes hundreds or even thousands—designed for parallel processing. GPUs excel in handling repetitive, data-intensive tasks, making them ideal for gaming, video rendering, and more recently, machine learning and AI applications. Learn More abo...

  What is  DNS? The internet connects devices, servers, and websites using special numbers called IP addresses. Computers understand these numbers, but it's hard for people to remember them. In the past, this wasn't a problem because there weren’t many websites. But as the internet grew, it became harder to remember all the numbers. That's when DNS (Domain Name System) was created. It works like a phonebook, changing easy-to-remember website names (like www.servers99.com ) into IP addresses. This makes it easier for us to access websites without needing to remember numbers. How DNS Works DNS works like the contact list on your phone. When you save a person’s name with their phone number, you can search for their name to find their number. Similarly, DNS translates a website name into a unique IP address. When you type a website's address in your browser, your request first goes to a "recursive server" (usually provided by your internet service provider). This ...

What is Network Latency? Network latency is the time it takes for data to travel from a client to a server and back. When you send a request, the data passes through several steps, including local gateways and routers, each adding a small delay. The total time for the data to complete this round trip is called network latency, which is usually measured in milliseconds (ms). In fast-paced activities like stock trading, even reducing latency by just one millisecond can make a big difference. For most businesses, though, the goal is simply to provide quick responses to users. Lowering latency helps avoid delays that can annoy customers. Network Bandwidth vs. Network Latency People often confuse network latency with network bandwidth, but they are different: Latency is the time it takes for data to travel from one place to another, affected by distance and the number of routers the data passes through. Bandwidth is the amount of data that can be transferred over a network in a certain ti...

  Before we explain BGP, we will start with the Autonomous System and Dynamic Routing Protocol. Then, it will be easy to understand the concept of BGP. What is an  Autonomous System? An  Autonomous System (AS)  is a collection of network devices, such as routers, managed by a single organization. Its main role is to control the flow of data within its network and how it connects to other networks on the internet. When multiple routers in the same local area (like inside a company) are connected, they share data with each other. Once this data is shared and the routers work together, they form a group. This group is what we call an  Autonomous System. What is the Dynamic Routing Protocol? A Dynamic Routing Protocol is a method used by routers to automatically find the best path for data to travel across a network. It helps routers adjust routes when the network changes, without needing someone to set them manually. There are  2 types  of Dynamic Routing...
