. Introduction In this beginners guide, I am going to explain the basic & important terms of computer networks such as NIC, IP Address, MAC & ARP. This will greatly help you set up your network basics right before you look for advanced stuff. Often we straight away jump into using tools and learn quickly from the various technical papers but we tend to forget the basics. This often causes us to lose the ground and eventually lose interest in the same.

From that perspective, this tutorial will help you get your ground stable on network basics and get going! Know the Terms - IP Address, NIC, MAC You must be familiar with the term IP address. Just like your home has a mailing address in the same way any computer or device connected to the internet have a mailing address called the IP address. It can either be static or dynamic. In case its static then it will remain unchanged every time you connect to a network and if its dynamic then a local DHCP server grants you a new IP address every time you connect to internet.

The patch program is included with Mac OS X, but you need to use it from the command line via. Does anyone have a tutorial for patching with xcode? Leah Buchley has an excellent tutorial, and you should follow it. I've reduplicated it here in case the site goes down. I've reduplicated it here in case the site goes down.

So with machines coming and going on networks, and IP addresses ever changing, how do other computers on your network find Redbeard? The secret (well, not really a secret; just a fact that veteran administrators know so well, they forgot to tell you) is this: every networked device actually has two addresses. One is the IP address, which might or might not change. The other is the MAC address, which is fixed to the device (can be changed too, ).

When you connect a computer to your Ethernet LAN, do you know what you're plugging the Ethernet cable into? From the outside, it looks like you're plugging it into a metal case, but you're not. Inside the case is a Network Interface Card (NIC). A NIC is a special hardware card within any networked device (computer, printer, router, etc.) that handles all the technical aspects of sending and receiving data packets over a computer network. Like your mailing address at home, your computer's NIC has a unique address.

This address must be unique, otherwise, network traffic cannot find its way to the right computer. The distinctive address that identifies a NIC is called the Media Access Control (MAC) address. A MAC address is formatted as a six-byte, hexadecimal number, like this 00:90:7F:12:DE:7F A MAC address is a unique character string, and since it identifies a specific physical device - one individual NIC - the MAC address, by convention, never changes for the life of the NIC.

Two NICs never have the same MAC address (unless some manufacturer screws up royally which has happened). Because your NIC's MAC address is permanent, it's often referred to as the 'real' or physical address of a computer. Why do we need IP when we have MAC? Actually MAC address are fixed hence they are not as scalable compared to IP address. IP address have several other features like subnetting and supernetting which gives a logical understanding of the presence of a machine in a network.

These facilities are not with the MAC address. Also MAC address are not routable. The Internet Protocols will not treat them as an address of a source or destination. Hence IP address in many ways simplifies our task. The malleable IP address gives your network some flexible manageability.

The never-changing MAC provides a specific, reliable address for a physical device. Or you could say, we have the long and the short of it.

IP addresses route a packet across the whole global Internet, while MAC addresses help the packet make the small, local hop between hardware devices. Sophisticated networking is possible because each of your networked devices has both a MAC and an IP address. With that comes the next question, How MAC and IP co-ordinate? Lets bring up ARP The simple definition that we study in local networking books about ARP is - network layer protocol that is used to convert IP address into MAC address.

Lets get into more details, We began by wondering, 'How do devices on a local network become aware of one another?' NICs and MACs are important pieces of the answer, but your network must learn to pair a MAC address with the IP address for the same machine. It does so using a technique called Address Resolution Protocol (in short ARP). Think of ARP as network roll call. Remember the first day of your college/school?

At the beginning of class, the teacher called from a list of names, expecting you to reply when she called yours. She did this to associate your name with your face. Every student heard every name, but answered only to his or her own name.

ARP uses a similar technique to associate an IP address to the MAC address. Let's assign Abhinav the IP address, 192.168.39.101, and suppose his NIC has the MAC address, 00:A0:24:30:2E:13.

And suppose he need to send a file to Jaya or more literally, to her computer. When Abhinav attempts to send jaya a file, Abhinav first obtains Jaya's IP address. Upon seeing that the IP address is local (on the same subnetwork), Abhinav knows he is capable of sending the file to her destination, if he learns the 'real' (MAC) address associated with that IP address. To learn the MAC address, Abhinav does what your teacher did on the first day of school/college. He calls out to the entire local network asking that the computer with the IP in question reply 'Here!'

With a MAC address. Let's say that Jaya has the IP, 192.168.39.148. To find the MAC address for Jaya, Abhinav would send the following (simplified) ARP request: From: (Abhinav's MAC address) To: (Broadcast address) Packet Content 00:A0:24:30:2E:13 FF:FF:FF:FF:FF:FF Who has 192.168.39.148? Tell 192.168.39.101.

Notice the special address in the 'To' field above. That special address (all Fs) is the MAC broadcast address. Anything sent to that address goes to every computer on LAN segment. All those computers receive the message, but ignore it, because it doesn't pertain to them - with the exception of Jaya.

Because Jaya is 192.168.39.148, she replies with her MAC address, like this: From: (Jaya's MAC address) To: (Abhinav's MAC address) Packet Content 00:A0:24:30:4C:23 00:A0:24:30:2E:13 I have 192.168.39.148 This is how Abhinav will finally succeed in finally sending his file (not a love letter) to Jaya after identifying her MAC or physical address. In short Abhinav ARPed Jaya. Here is a picture to demonstrate this process. Having successfully ARPed, Abhinav stashes the newly-learned MAC/IP pair in an ARP cache.

The ARP cache is a small segment of memory your computer reserves to temporarily store a table of MAC addresses and their associated IP addresses. Your computer keeps this table for efficiency so that it doesn't have to keep broadcasting ARP requests to computers it has already queried. If Abhinav need to send something else to Jaya soon (maybe a love letter this time), Abhinav will obtain Jaya's MAC address from his own ARP cache rather than querying it again. Conclusion Hope this tutorial will help you to clear most of your doubts on networks basics. When you have sound basics, you can easily solve bigger problems.

Last month, the release of: a full-featured development environment to help developers on the Mac create apps, games, and services for mobile, cloud, and web. It’s natively designed for macOS, so both the design – from the toolbar to the file dialogs – and the developer workflow should feel right at home to Mac users. It is also a best-in-class advanced C# code editor – with IntelliSense and a refactoring experience that includes a preview of the proposed code changes. Mobile and web developers working on the Mac will appreciate the additional features that Visual Studio for Mac provides C# developers, and developers that have used Visual Studio on Windows will feel instantly at home with the familiar solution explorer and menu options. Visual Studio for Mac features first-class support for NuGet – the.NET package manager – which provides access to thousands of prepackaged code libraries; you can also code in F#, and yes, C# 7 features are fully supported! Cross-platform capabilities don’t end there – Visual Studio for Mac shares the same solution format as its Windows counterpart. Teams with developers on both Mac and Windows can open and work on the same projects, sharing code across platforms and apps.

Built-in version control makes it easy to work with small or large teams, on local and remote Git repositories (including GitHub and BitBucket). Mobile Development Visual Studio for Mac has a heritage in Xamarin Studio, and thus supports cross-platform application development for iOS, Android, and macOS with. By installing the iOS and Android SDKs, you can build cross-platform mobile apps using C#, with complete access to the underlying native APIs (including tvOS and watchOS). It includes drag-and-drop user interface designers for both iOS and Android, giving you the ability to interactively create native iOS Storyboards and Android XML layouts. Or, if you prefer, you can use Xamarin.Forms XAML to create a re-usable cross-platform user-interface (with a real-time preview option). Whichever option you end up choosing, apps using Xamarin always render native controls and run at native speed.

To make getting started with mobile development easy – we also announced the preview of, enabling you to start experimenting in seconds. Just pair the app on your phone with Visual Studio for Mac using a QR code and instantly see your app running and you can make live edits along the way. When you want to build complete apps, you can use the simulators and emulators available or test on real phones. Visual Studio for Mac can even help you build and deploy your finished apps to the App Store and Google Play–the archive for publishing build option will guide you through the code-signing and uploading process. Web and Cloud Visual Studio for Mac isn’t just for mobile, however. The web editing experience on Visual Studio for Mac comes directly from code ported from Visual Studio (on Windows). It includes support for developing.NET Core apps and ASP.NET Core back-ends, which can be deployed to Windows, Linux, or on.

The editor also supports full HTML, CSS, and JavaScript syntax highlighting and IntelliSense for your web app’s front-end. To build for the cloud, the Connected Services feature helps add Azure functionality to mobile apps without leaving the IDE, and.NET Core web apps can be published directly to Microsoft Azure. There’s more cool stuff in the pipeline, including Azure Functions support and the ability to deploy using Docker containers, both of which are currently available in preview. Games too Additionally, Visual Studio for Mac includes the ability to build games using Unity, the most popular gaming engine around. You can directly edit your Unity scripts with the same world-class C# editing experience, including full syntax highlighting and IntelliSense. Debugging is also just a button away, with full debugger support for Unity games. For mobile games, you can also use Xamarin for access to native gaming APIs like SpriteKit, or cross-platform options like CocosSharp and UrhoSharp.
