Common network issues and solutions in computer networks:- Computer networks are an important part of modern organizations. Data is sent and received using it. And it is used for communication and connecting resources. It is necessary to fix the problem of the network. So that the functionality of the network can be increased and made efficient. 1. Connectivity problems :- Problem: If a user is unable to connect to the network. Solution:- Reboot the computer and router: If the user is unable to connect to the network, then he can connect to the network by resetting the circuit first. Check the network cable and connection: if the user is unable to connect to the network. Then check the network cable to see if the network cable is connected correctly or not. And whether the network cable is broken or not. Check the settings of the network adapter: If the user is unable to connect to the network. Then check if the network adapter is connected correctly or not. Check IP address: If the ...

Network Troubleshooting Methodologies: Network Problem Solving Techniques :- Network problem solving is an important task whose purpose is to identify the network problems and fix them. Therefore, this process demands technical knowledge and use of the right tools. Network management, network engineers, and IT assistants are responsible for identifying and solving network problems. In this article, network troubleshooting and methods will be explained. Problem identification :- The first step in network problem solving is to identify the problem. Many steps have been taken for this: 1. Network monitoring: Any unusual activity occurring on the network can be identified using network monitoring tools. These tools monitor the availability, performance, and security of the network. 2. User reports: It evaluates the problems and complaints received from the users. Then it is known where the problem is occurring in the network. 3. Log File Analysis: Evaluates the log files of network devi...

What is a firewall: An integral part of computer security :- In the context of computer and network security, a firewall is a special device that prevents unauthorized access and helps to secure data. And it restricts network traffic and only allows data coming from reputable sources. Therefore, through this article, the types of firewalls, definitions, benefits, and their functions and rules for implementing them will be explained. Definition of firewall (structure):- A firewall is a security system that has been created to keep the network safe. Its main goal is to block unauthorized traffic and allow only the traffic that comes with the right credentials. It filters network traffic and monitors the data coming and going in the network. Types of firewall :- There are two types of firewalls: software firewalls and hardware firewalls. Apart from this, there are other types of network security. 1. Software Firewall: A software firewall is a program that is applied to a computer or netwo...

Concept of Switching :- In this networked world, switching is an essential function for data communication between specific devices. Data packets are sent to their destination through switching. To understand it better, know the types of switching - 1. Circuit Switching: In circuit switching, a path is arranged for the communication of data. This path remains in place until the communication is complete. This technique is widely used in telephone networks. For example, when someone calls someone, a dedicated path is created that remains in place until the call ends. 2. Packet Switching: In packet switching, information is broken down into smaller pieces called packets. Each packet contains information about the source and its destination in addition to the data. These packets move freely through the network and are reunited after reaching their destination. It is used a lot on the Internet. 3. Message Switching: In message switching, all the messages are sent at the same time. Each mes...

Wi-Fi Network Setup and Troubleshooting Wi-Fi Networks :- Nowadays, in the age of technology, the use of Wi-Fi has increased for internet access. The use of Wi-Fi networks has made internet connectivity easy in homes, offices, and public places. It is often seen that setting up Wi-Fi is difficult for many users. Set up a Wi-Fi network :- Essential Equipment:- 1. Router: To connect to a Wi-Fi network, we need a good router. Which connects to the wifi network and gives us internet. 2. Modem: To connect to a Wi-Fi network, we also need a modem along with the router. 3. Internet Connection: To connect to a Wi-Fi network, an internet service is required. 4. Ethernet Cable: To connect to a Wi-Fi network, Ethernet is required to connect the router and modem. Step 1. Hardware setup :- 1. Modem connection: To connect to the wifi network, connect your modem to the line provided by the internet provider. 2. Router connection: To connect to the wifi network, connect the modem and router via Eth...

What are 802.11ac and 802.11ax? 802.11ac and 802.11ax are very important standards for networking and Wi-Fi usage. Both these standards have been created by the IEEE (Institute of Electrical and Electronic Engineers). It was created to increase the speed and performance of Wi-Fi networks. Introduction to 802.11ac :- Wi-Fi 5 is also known as 802.11ac. It is a standard of Wi-Fi technology that runs on the 5 GHz band. It is used to increase high data transfer and performance. Features of 802.11ac :- 1. High data rate: The 802.11ac standard increases high throughput to 1.3 gigahertz per second (Gbps). It is much faster than 802.11n. It is used for high-speed data downloads and for streaming and gaming. 2. Wide channel bandwidth: It uses 802.11ac 80 megahertz (MHz) and 160 MHz channels to send data at the same time. It works with high throughput. 3. Multi-user MIMO (MU-MIMO): It uses the 802.11 ac standard multi-user MIMO to send data to multiple devices at the same time. Using this, data ...

Difference between static and dynamic routing protocols :- The use of routing protocol is very important for networking. These protocols create routes to send network data packets from one computer to another. The routing protocol is divided into two parts. The first is a static routing protocol, and the second is a dynamic routing protocol. To know the difference between these two protocols, a network administrator and IT professional are required. Static routing protocol:- Static routing is a protocol in which a routing table is created manually by the network administrator. In this, the decision for routing work is taken permanently. And the routing does not change until the administrator makes a change. Advantages of static routing protocol :- 1. Simplicity: Static routing protocol is very simple. And it is easy to understand. Static routing protocol is a very good protocol for small networks. 2. Less overload: In static routing protocol, there is less overload on the network. Bec...
