Links-Extractor is a small Python utility that takes a single URL and pulls out every hyperlink on the page, separating them into internal links (pointing to the same domain) and external links (pointing elsewhere). Splitting links this way is useful for SEO audits, for finding broken or outbound links, for mapping the structure of a site, and as a starting point for a larger crawler. You give it a URL and get back two clean lists you can save or process further. The project is open source and meant to be easy to read and adapt. It is archived on Zenodo with a citable DOI. DOI: https://doi.org/10.5281/zenodo.20672987

Learn more about VPN and PPTP: https://com.puter.tips/2018/09/free-vpn-service-for-router.html OSI model layers The main concept of OSI is that the process of communication between two endpoints in a network can be divided into seven distinct groups of related functions, or layers. Each communicating user or program is on a device that can provide those seven layers of function. In this architecture, each layer serves the layer above it and, in turn, is served by the layer below it. So, in a given message between users, there will be a flow of data down through the layers in the source computer, across the network, and then up through the layers in the receiving computer. The seven layers of function are provided by a combination of applications, operating systems, network card device drivers and networking hardware that enable a system to transmit a signal over a network Ethernet or fiber optic cable or through Wi-Fi or other wireless protocols. Data Link (Layer 2)...

What is a Virtual Private Network (VPN)? A virtual private network extends a private network across a public network and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. Why have a VPN? A VPN, or virtual private network, is a secure tunnel between two or more devices. VPNs are used to protect private web traffic from snooping, interference, and censorship. Virtually anyone can benefit from VPN, whether it is to access content outside of your territory, protect your private information, or get access to cheap airfares. There are many attributes that must be considered when choosing a VPN as well; not all VPNs were created equal. There are two basic VPN types: 1. Remote Access VPN 2. Site – to – Site VPN Types of VPN protocols: The above two VPN types are based on different VPN security protocols. Each of these VPN protocols offers different features and le...

These banks can accept a restricted deposit, which is currently limited to ₹1 lakh per customer and may be increased further. These banks cannot issue loans and credit cards. Both current account and savings accounts can be operated by such banks. Payments banks can issue services like ATM cards, debit cards, net-banking and mobile-banking.

The Internet we know is changing! IPv6 is already in use as we ran out of IPv4 addresses, 802.11ac standard in use which provides hi speed wireless communications and now comes HTTP/2 that is Hypertext Transfer Protocol 2.0. The current version in use is HTTP 1.1 which will soon be replaced by HTTP 2.0. It is based on SPDY protocol. HTTP 1.1 is standardized in RFC 2068 published in January 1997 and HTTP 2.0 is standardized in RFC 7540 published in May 2015. It is developed by IETF HTTPbis Working Group which includes Mozilla and Google developers. HPACK compression was devised for header compression as GZIP was not safe anymore. HPACK is standardized in RFC 7541 published in May 2015. Compression reduces RTT for header transfer due to slow start of TCP.
