In today's digitally-driven world, data transmission has become essential for businesses. From sending crucial emails to performing online transactions, data transmission techniques have revolutionized the way businesses operate. Network transmission refers to the process of transferring data from one device to another in a digital format. For data transmission, a reliable network is necessary, which is capable of sending and receiving data packets swiftly and securely.
Transmission Control Protocol/Internet Protocol (TCP/IP) is the most popular standard for data transmission. TCP ensures that the data sent between devices is delivered accurately, while IP addresses ensure that data packets reach the proper destination. Data transmission can occur over wired or wireless networks, including the Internet, Ethernet, Wi-Fi, and Bluetooth.
Furthermore, businesses must consider the bandwidth and latency of their networks when it comes to data transmission. Bandwidth refers to the amount of data that can be transmitted over a network in a given amount of time, while latency refers to the delay between transmitting and receiving data packets. A high bandwidth and low latency network is essential for businesses that require high-speed data transmission for applications such as video conferencing, cloud computing, and online collaboration.
In conclusion, data transmission is a crucial aspect of modern businesses. It is necessary to ensure that networks are reliable and secure, while also providing enough bandwidth and low latency to enable high-speed data transfer.
Network Architecture
A network's architecture refers to the design and layout of devices, software, and protocols used to create a network. A well-designed network architecture is essential for businesses to ensure that their networks are secure, scalable, and efficient. The three main types of network architecture are bus topology, star topology, and mesh topology.
A bus topology network consists of a single cable that all devices connect to, making it a simple and inexpensive design. However, it is not suitable for larger networks as it can become congested and unreliable. In contrast, a star topology network uses a central hub to connect all devices, providing better performance and easier maintenance. Mesh topology, on the other hand, provides a network where every device can communicate with every other device, making it ideal for large networks where every device needs to be connected.
Network architecture also involves the use of protocols, such as TCP/IP and Ethernet, to ensure that the network is reliable and secure. Proper routing techniques, such as Virtual Local Area Network (VLAN), allow businesses to separate network traffic based on department or logical functions.
In conclusion, choosing the right network architecture is essential for businesses to ensure that their networks are secure, scalable, and efficient. Proper protocols and routing methods contribute to a robust network architecture that can meet the evolving needs of today's business landscape.
Network Administration
Network administration refers to the management of networks, including the day-to-day maintenance and security of the system. Network administrators ensure that the network is running smoothly, troubleshoot any issues, and implement new technologies to improve the network's efficiency. Network administration also involves maintaining security protocols to protect against cyber threats, such as malware, phishing attacks, and data breaches.
Network administration involves several tasks, including network monitoring, patching, backups, and resource allocation. With the rise of remote work, network administrators must also ensure that remote workers have secure and reliable access to the company's network.
Network administrators use a variety of tools to perform their tasks. Remote monitoring and management (RMM) tools allow administrators to monitor the network and fix any issues remotely. Backup and disaster recovery (BDR) solutions ensure that data is recoverable if there is a catastrophic event, such as a cyber-attack or natural disaster.
In conclusion, network administration is a crucial aspect of modern businesses. A well-managed network ensures that businesses can operate effectively and efficiently while minimizing security risks. Network administrators use a variety of tools and techniques to ensure that the network is functioning as intended and can respond quickly to any issues.
Conclusion
In today's digital world, computer networks are essential for businesses. They enable businesses to operate efficiently, collaborate effectively, and compete in a global marketplace. Businesses must consider the various aspects of computer networks, including data transmission, network architecture, and network administration, to ensure that they have reliable, secure, and scalable networks that can meet the challenges of the modern business environment. By doing so, businesses can take advantage of the power and potential of computer networks to achieve their goals and drive success.
Regardless how you deployed your network. I mean every network topologyneeds to perform well apart from its pros and cons. In this lecture we are going to discuss the important network performance parameters which tell you how good is your network.
Network performance is measured by the following parameters
- Bandwidth
- Throughput
- Latency
- Jitter
Over the two decades, we have observed many technology replacements which totally astonished the human race.
From screen touch smartphones to the VR technology, there are number of advancements that define the new era of the tech-driven world.
The startup invented a new way to transfer the data from one smartphone to other more efficiently with a single touch and named it ‘KIss connectivity’.
The Kiss connectivity is the fastest channel to transfer the data between the devices with the speed of 6Gb per second.
Consider, you need to transfer data from one smartphone to another and both the devices have kiss connectivity chip inbuilt in them.
The chip embedded in both device let them connect magnetically and create a channel to transfer the data instantly.
We can find wireless networks everywhere, and they are accessible by everyone within the transmission range of the router.
But most of the time a password is required to be able to connect with the network.
But all the networks are vulnerable to many attacks.
There is a number of ways to hack a wireless network, the standard way is to capture a handshake and then brute-force the password.In this tutorial, you are going to learn the quickest method of How to Hack / Crack WiFi Password.
We are going to use the Fern WiFi Cracker tool in this tutorial.
