Killer Application (Killer App)
A Killer Application (Killer App) is a program that compels customers to buy new hardware by appealing to their desires. It's a common phrase in the tech field. The idea of a "killer app" comes from the gaming industry, which refers to an application that makes you buy a console so that you can play it. Examples include Super Mario Bros., Pokémon, and Halo 2. In recent years, several companies have begun using the term "killer app" for their products—like Apple's Siri or Microsoft's Cortana—even though these aren't apps. The phrase has become so common in tech circles that many people don't even realize there's an original meaning: an app that gets you to buy the product it runs on! Killer Apps are the best. They're like a cross between a headache and a hangover—and they're much more fun than either of those things unless you love headaches and hangovers. Killer apps are known for creating large followings that can lead to hardware or device purchases, which is why they are also referred to as "essential factors." If you're looking for an example of killer apps in action, try thinking back to the days when Windows 95 was released. It was such a big deal that people lined up outside of stores to get their hands on it—and then they stayed there for days because they had no idea how to use it! "Killer apps" are the things that make us go, "wow, that's so cool." They're the things that help us buy new technologies and get excited about them. In the early days of computing, killer apps were often game-changing applications like VisiCalc, the first spreadsheet program, or Lotus 1-2-3, which helped turn computers into business tools. Email is a classic example of a killer app in the Internet era. It's boring technology—but it was so valuable for so many people that people were willing to pay for email addresses and use them regularly. So, what's your favorite killer app?

The Kerberos protocol relies on the ticket-granting server, the TGS, to act as a trusted third party. The ticket-granting server is a component of the logical key distribution center or KDC. The use of a ticket for a particular function, such as gaining access to a network service, can be verified by a TGS. It's like when your mother permits you to do things, but only on the condition that you don't act up. The TGS first verifies the identity of the user requesting the ticket, and then it generates a new key with an expiration date set in the distant future. The new ticket will authenticate the user to the target server by encrypting certain information about the user's identity and other information required for the authentication process. Users will present this ticket to an authenticator located on the service in question whenever they need access to that service. When the authenticator checks with the KDC, the KDC will return proof of authorization if it discovers that valid credentials have been presented. This allows the authenticator to confirm that the user has been authenticated. To put it briefly, the ticket-granting service (also abbreviated as TGS) is the place to go when you want to go to another location. When you want to enter the carpool lane, you must first inquire with the gatekeeper, also known as the TGS, as to whether or not it is acceptable. The gatekeeper will examine your credentials to determine whether or not they are legitimate before providing you with a new ticket for the carpool lane. The TGS functions similarly to an automated checkpoint that restricts passage to only those with valid tickets. In this scenario, the gatekeeper checks for valid tickets by ensuring that the individual in question is in possession of a valid driver's license and is not under the influence of alcohol or driving with a license that has been suspended.

Imagine you are at a party and need to speak to someone on the other side. What would you do? REST is like a secret code you and others may use to interact remotely. Now, bear with us as we get more in-depth with you. REST is an architectural paradigm for constructing web services that use HTTP (the same protocol as the World Wide Web) to communicate data. It is predicated on the resource concept, denoted by URLs and may be accessed, generated, modified, or removed by utilizing conventional HTTP methods like GET, POST, PUT, and DELETE. For illustration's sake, let's pretend you're keeping track of your exercises with the help of an app. The app communicates with a web service that stores your exercise data in the cloud via REST. Launching the application makes a GET request to the web service to get your exercise history. This information is then provided in a standard format, such as JSON or XML. When you save a new exercise, the app makes a POST request to the web service to create a new resource, and when you change an existing workout, it sends a PUT request to update the help. You're aware of one of the beautiful things about REST. It is easy to use, adaptable and widely used in the IT sector. As it adheres to the HTTP protocols and formats that are universally accepted, it is simple to implement in any computer language or environment. It is also an excellent tool for developing online services that many clients, including web browsers and mobile applications, can access. Hold on, and there's much more to it! REST is merely one component of a broader ecosystem of technologies enabling web services development. Other technologies in this ecosystem include SOAP and GraphQL. Each has a unique set of benefits and drawbacks, and selecting the best option depends on the application requirements you're working on. Therefore, as you now know, REST is comparable to a top-secret coding language that enables computer systems to communicate with one another through the internet. It's an architectural approach for constructing online services that use HTTP to send data across systems. It's simple, scalable, and extensively used in the tech sector. Even though it is only a single component of a much bigger ecosystem, it is a potent instrument for developing cutting-edge online apps.
