What is WAP?

WAP stands for Wireless Application Protocol. This is a well-known and commonly used standardized protocol which defines how wireless communication can take place between mobile devices and a wireless network. This could include devices such as radio transceivers, cell phones, world wide web, newsgroup, instant messaging and any device that can be used for Internet access. Devices which are based on WAP can interoperate as technology advancement happens over time.

File sharing is something which is part of our daily activities. This is also commonly referred to as P2P or Peer-to-Peer sharing. This could be sharing files between two nodes in a network or between a client and a server or between two nodes not within the same network. Any multi-user environment will require a file sharing mechanism.

What is net neutrality?

In today's digital world net neutrality has become increasingly significant. As an Internet user, something that all of us should be aware of. Net neutrality is a fundamental law that several governments impose on Internet Service Providers (ISP). This ensures all data irrespective of the content is treated equally. With this, the Internet service provider will not be able to charge differently to its users based on content, platform, application or website being accessed.

Our home router has become an internal part of the global communication footmark when the use of the Internet has developed to contain home-based telework, entertainment, personal financial management, social networks, school work, and businesses. The router facilitates the broadened connection. Almost all these devices are pre-configured by the company that made and are plug and play for immediate use. After installing a router at home, people frequently connect directly to the World Wide Web without conducting any additional configuration. People might be reluctant to enhance safeguard configurations because those configurations may seem a bit difficult or people are unwilling to spend more time with these advanced configuration settings.

There is really no one specific thing that you can say determines the speed of your internet connection because there are several players and components responsible to deliver internet to your PC or laptop. Internet speed is not just determined by the speed of your computer’s processor as many people think.

What is ARP Spoofing?

The Address Resolution Protocol (ARP) Spoofing attack, also called ARP Cache Poisoning or ARP Poison Routing, is a technique by which an attacker sends spoofed ARP messages onto a Local Area Network (LAN). It is used to allow the attacker access to incoming internet traffic on a LAN by having their Media Access Control (MAC) Address be linked to the Internet Protocol (IP) Address of another host (usually, the default gateway). Through this, they’re able to receive incoming traffic intended for that IP Address which allows them to intercept the data, modify traffic, or even stop all traffic on the network. Because of this, the technique is often used to open up the possibility of other attacks such as a Denial of Service (DoS) attack, a man in the middle attack, and a session hijacking attack. The success of the attack depends heavily on the attacker gaining direct success to the targeted local network segment and it can only be used on networks which use ARP.

What is a Smart Contract?

A smart contract is a computer protocol which was designed with the goal of digitally facilitating, verifying, or enforcing the negotiation of a contract. Through the protocol, credible transactions can be successfully processed without the use of a third party and are trackable and immutable; that is, they cannot be modified or removed after being successfully completed. Their entire purpose for being designed is to provide a higher level of security unattainable by traditional contractual law and to reduce other transaction costs associated with the traditional process.

What is a Network?

A network is a connection between one or more nodes (devices) regardless of distance and size. They are established for the sake of communication of data between the nodes. To accomplish this, the nodes will utilize circuit switching, message switching, or packet switching to send the data through from one signal to another. They are the basis for telephone networks, computer networks, and the Internet as a whole.

The User Datagram Protocol (UDP) is one of the core protocols of the Internet Protocol (IP) Suite in the transport layer. The protocol’s primary purpose is for the use of sending messages (datagrams) between two endpoints across the Internet without the need of a pre-existing data path from prior communication between the endpoints. This is what is referred to as connectionless communication and is ideal in situations where error-checking and error-correction are not needed between two endpoints. In these scenarios, the datagrams can be sent between the two endpoints faster than using the Transmission Control Protocol (TCP) and Stream Control Transmission Protocol (SCTP) as the overhead generated from error-checking and error-correction is no longer a factor. This makes UDP very popular and a very optimal solution in these types of situations as it would be more preferred than its counterparts.

Public Wi-Fi is a lifesaver if you're trying to save on data usage or you need the Internet access, but sometimes the consequences of using public Wi-Fi can outweigh its convenience. Whether you're in a coffee shop, public library, university or an airport, all free Wi-Fi hotspots are equally susceptible to hackers and other data thieves. To mitigate these risks, users must take preventative measures to ensure that they are using public Wi-Fi safely.
