Link state routing is a method in which each router shares its neighborhood’s knowledge with every other router on the internetwork. In this algorithm, each router in the network understands the network topology and then makes a routing table depending on this topology. Each router will share data about its connection to its neighbor, who will, consecutively, reproduce the data to its neighbors, etc. This appears just before all routers have constructed a topology of the network. In LSP, each node transmits its IP address and the MAC to its neighbor with its signature. Neighbors determine the signature and maintain a record of the combining IP address and the MAC. The Neighbor Lookup Protocol (NLP) of LSP derives and maintains the MAC and IP address of every network frame accepted by a node. The extracted data can support the mapping of MACs and IP addresses. The link-state flooding algorithm prevents the general issues of broadcast in the existence of loops by having every node mainta

The smart home is evolving. To date, if you've wanted to get into developing a smart home, you've had to deal with the multitude of smart home ecosystems, and making sure that each device you buy is compatible. That, however, may soon change — thanks to new smart home standard called Matter. Matter isn't available just yet, but when it is finally released, it could completely change how you buy smart home products, for the better. All of the best smart home devices could soon support the standard, helping them all work together nicely, and ensuring that no matter what products you buy, you'll be able to use them. Matter is basically the name of a new smart home connectivity standard . But this standard is a little unlike others. That's because of the fact that it's being developed by the Connectivity Standards Alliance, which counts hundreds of companies as members. That includes the likes of Google, Alexa, and Apple. So, whether you prefer to use Google Assista

While you’re here, if you’ve been getting annoyed by Alexa’s pestering you to rate that cheese grater you bought two months ago (this happened to me at 9:30PM when I asked Alexa to read my Audible book), there is a quick fix. Scroll a bit further down on the same Shopping Notifications page and toggle off “Request to rate products you’ve purchased.” You can also stop Alexa from announcing the latest deal on the laundry detergent you usually purchase by toggling off “Recommendations and Deals.” There are other options in here you might want to check out if you often find your Alexa speaker flashing yellow like it’s trying to get your attention (which it is). If you use Amazon’s Subscribe & Save program Alexa can audibly notify you if an item in your upcoming delivery is out of stock, among other things. You can toggle this option on or off under Order Updates, this will affect announcements about any order updates. You can use this screen to stop Alexa from randomly offering up “per

Echo smart speakers and smart displays have a handy feature that can show and tell you when there’s a package sitting on your doorstep and even what’s in it. While this can be helpful most of the time, around the holidays it could seriously ruin some surprises. Avoid making any Grinch-like moves this holiday and manage your Amazon shopping notifications in the Alexa app to help keep the magic alive. Alongside options for tailoring package announcements, the notifications section of the app also has a number of settings you can toggle on or off to help make the voice assistant a little more helpful when it comes to purchases you make on Amazon. Below are a few of the most useful that you might want to tweak this holiday season. Open the Alexa app. Tap on More in the bottom right hand corner. Select Settings > Notifications > Amazon Shopping . Under “Say or Show Item Titles” toggle off “including items in your shopping cart marked as gifts, or those that might be gifts during major

If you use a company-owned PC, you may have seen a legal notice displayed before you sign in to Windows. Here’s how you can do the same thing on your own PC and display a message with any text you want. If you’re willing to dive into the Windows Registry or Local Group Policy Editor, there are some interesting things you can do surrounding Windows sign in.  If you have a Home edition of Windows, you will have to edit the Windows Registry to make these changes. You can also do it this way if you have Windows Pro or Enterprise, but just feel more comfortable working in the Registry. (If you have Pro or Enterprise, though, we recommend using the easier Local Group Policy Editor, as described in the next section.) Standard warning: Registry Editor is a powerful tool and misusing it can render your system unstable or even inoperable. This is a pretty simple hack and as long as you stick to the instructions, you shouldn’t have any problems. Open the Registry Editor by hitting Start a

Windows has always existed to be a stage for the world’s innovation. It’s been the backbone of global businesses and where scrappy startups became household names. The web was born and grew up on Windows. It’s the place where many of us wrote our first email, played our first PC game and wrote our first line of code. Windows is the place people go to create, to connect, to learn and to achieve – a platform over a billion people today rely on. The responsibility of designing for that many people is one we don’t take lightly. The past 18 months brought an incredible shift in how we used our PCs; we went from fitting the PC into our lives to trying to fit our whole lives into the PC. Our devices weren’t just where we went for meetings, classes and to get things done, but where we came to play games with friends, binge watch our favorite shows and, perhaps most meaningfully, connect with one another. In the process we found ourselves recreating the office banter, the hallway chatter, worko
