What is a firewall and how does it work What is a firewall and how does it work Jul 08, 2025 am 12:11 AM

A firewall is a network security system that monitors and controls network traffic through predefined rules to protect computers or networks from unauthorized access. Its core functions include: 1. Check the source, destination address, port and protocol of the data packet; 2. Determine whether to allow connections based on trust; 3. Block suspicious or malicious behavior; 4. Support different types such as packet filtering firewalls, status detection firewalls, application layer firewalls and next-generation firewalls; 5. Users can enable built-in firewalls through operating system settings, such as Windows Security Center or macOS system preferences; 6. The firewall should be used in combination with other security measures such as strong passwords and update software to enhance protection.

Can my wifi provider see my browsing history Can my wifi provider see my browsing history Jul 01, 2025 am 12:35 AM

Yes, WiFi providers can see some of your browsing information. Specifically: 1. The WiFi provider can see the domain name, Internet time period, device type and traffic size of the website you are visiting, but cannot view the specific content of the HTTPS website; 2. The home WiFi administrator can also view the connection records and some traffic content through the router background or parent control software; 3. Methods to protect privacy include using HTTPS websites, connecting to VPNs, enabling browser privacy mode, and avoiding sensitive operations on public WiFi; 4. The company or school network is usually more stringent, and may record logs, install a proxy server, or even force decrypt HTTPS traffic, so you should try to comply with regulations and avoid visiting irrelevant websites.

How to fix VIDEO_TDR_FAILURE (nvlddmkm.sys) How to fix VIDEO_TDR_FAILURE (nvlddmkm.sys) Jul 16, 2025 am 12:08 AM

When encountering the blue screen error VIDEO_TDR_FAILURE(nvlddmkm.sys), priority should be given to troubleshooting graphics card driver or hardware problems. 1. Update or rollback the graphics card driver: automatically search and update through the device manager, manually install or roll back to the old stable driver using NVIDIA official website tools; 2. Adjust the TDR mechanism: Modify the TdrDelay value in the registry to extend the system waiting time; 3. Check the graphics card hardware status: monitor the temperature, power supply, interface connection and memory module; 4. Check system interference factors: run sfc/scannow to repair system files, uninstall conflicting software, and try safe mode startup to confirm the root cause of the problem. In most cases, the driver problem is first handled. If it occurs repeatedly, it needs to be further deepened.

How to stop a program from connecting to the internet How to stop a program from connecting to the internet Jul 07, 2025 am 12:12 AM

To prevent specific programs from being connected to the network can be achieved through system firewalls or third-party tools. 1. Windows users can use their own firewall, create new rules in the "outbound rules" to select the program path and set "block connection"; 2. Third-party tools such as GlassWire or NetBalancer provide graphical interfaces that are more convenient to operate, but pay attention to source reliability and performance impact; 3. Mac users can control networking permissions through the command line with pfctl or using LittleSnitch and other tools; 4. A more thorough way is to use the network outage policy. The whitelisting policy prohibits all programs from being connected to the network by default and only allows trusted programs to access. Although the operation modes of different systems are different, the core logic is consistent, and attention should be paid to the details of the path and scope of the rules taking effect.

How to restart my wifi router How to restart my wifi router Jul 01, 2025 am 12:21 AM

Restarting the router can solve problems such as network lag and disconnection, because long-term operation will lead to high memory usage and system lag. Restarting can clean up cache and reset connections. 2. The correct steps include shutting down the machine and waiting for 30 seconds to 1 minute to discharge, turning off the light and the router in sequence and then turning on it in sequence, checking the indicator light to confirm the networking status. 3. When the network speed is slower, the device cannot access the Internet, the router is overheated, or the smart device is frequently disconnected, it should restart. Some routers support automatic restarting at regular intervals. 4. You can remotely restart through the management interface, enter 192.168.1.1 or 192.168.0.1 to log in to the background, find the restart option to complete the operation, which is suitable for situations where physical contact is inconvenient.
