What is Virtual Network Computing (VNC)?

Virtual Network Computing (VNC) is a system that allows remote control of a computer over a network connection. This technology is widely used in a variety of applications, including remote support, remote access, and virtualization. In this blog, we'll explore what VNC is, how it works, and some common use cases.


What is VNC?


VNC is a protocol that allows a user to remotely control another computer over a network connection. This protocol was developed by the RealVNC company and has since been adopted as an industry standard. VNC works by sending keyboard and mouse events from the remote user's computer to the remote computer, and then sending back the graphical output to the remote user's computer. This allows the remote user to see and control the remote computer as if they were physically sitting in front of it.



How does VNC work?


The VNC protocol consists of two main components: the VNC server and the VNC viewer. The VNC server is installed on the computer that you want to control remotely, while the VNC viewer is installed on the computer that you want to use to control the remote computer. When the VNC server is started, it listens for incoming connections from VNC viewers. When a connection is established, the VNC viewer sends keyboard and mouse events to the VNC server, which then sends back the graphical output to the VNC viewer.


VNC can be used with a variety of operating systems, including Windows, macOS, Linux, and even mobile devices. There are also many different VNC server and viewer software options available, including open-source and commercial solutions.


Use cases for VNC


There are many different use cases for VNC, including:


1.Remote support: VNC is often used by IT support personnel to remotely troubleshoot and fix problems on users' computers. This allows the support team to provide assistance without needing to physically be in the same location as the user.


2.Remote access: VNC can be used to remotely access a computer from a different location, such as from home or while traveling. This allows users to access their work or personal computer from anywhere with an internet connection.


3.Virtualization: VNC is often used in virtualization environments, such as with virtual machines or remote desktops. This allows multiple users to access and control the same virtual machine or remote desktop from different locations.


4.Remote gaming: VNC can be used to remotely play games on a more powerful computer from a less powerful computer or device. This allows users to play high-end games without needing to purchase expensive hardware.


Conclusion


Virtual Network Computing (VNC) is a powerful tool for remote control of computers over a network connection. It allows users to remotely control computers from different locations, making it useful for remote support, remote access, virtualization, and remote gaming. With its widespread adoption as an industry standard, VNC is likely to continue to be an important technology for remote access and control in the years to come.

Nvidia vs. AMD vs. Intel: Comparing AI Chip Sales

Image
In its second quarter financial release, the business recorded record revenue, with sales of AI chips playing a significant role. How do Nvidia, AMD, and Intel's sales of AI chips compare to those of other American rivals? This graph shows the revenue over time for each company using earnings data. A clear leader emerges. The businesses share revenue for their data center division even though they don't officially report revenue for their AI chips. Chips like central processing units (CPUs), data processing units (DPUs), and graphic processing units (GPUs) are included in the data center category. The latter are recommended for AI since they can effectively and simultaneously do a variety of easy tasks. Below, we compare the growth in quarterly data center revenue for Nvidia, AMD, and Intel. The calendar year is used to measure quarters. When revenue was updated later, we used the most recent revision that was made available. In 2023, Intel's Accelerated Computing Sys

Augmented Reality (AR) and Virtual Reality (VR)

Image
Augmented Reality (AR) and Virtual Reality (VR) are two emerging technologies that have the potential to change the way we interact with the world around us. While they are often grouped together, they are two distinct technologies with different applications and use cases. Digital information is superimposed on the physical world using augmented reality (AR) technology. It uses a camera or other sensors to capture the user's environment and then adds digital content on top of it. This digital content can take many forms, such as images, videos, or 3D models. AR is often used in mobile apps and games, where it can provide users with additional information about their surroundings. One of the most well-known examples of AR is Pokemon Go, a mobile game that overlays virtual Pokemon creatures on the real world. Users can catch these creatures and collect them as part of the game. AR can also be used for practical applications, such as providing users with information about nearby rest
