Summary: NFS is a file system mechanism that allows data to be stored and retrieved from multiple disks and directories over a shared network. Today this article will show you basic concepts and additional information on NFS. Overview NFS, short for Network File System, is initially developed by Sun Microsystems in 1984. NFS, a distributed file system protocol, allows users on client computers to access files over a computer network as if they were accessing local storage. Like many other protocols, NFS is built on an ONC RPC --Open Network Computing Remote Procedure Call system. As an open standard defined in the RFC (Request for Comments), NFS allows anyone to execute the protocol. Advantages NFS enables easy sharing of data among clients. It provides centralized management. It offers security by protecting only servers to protect data. Applications You can use NFS in the following ways: Deploy a Windows NFS file server in a non-Windows operating system environment to offer non-Windows client computers access to NFS file shares. Move applications from an operating system to another via storing the data on file shares accessible through SMB and NFS protocols. Use the Windows NFS file server to offer multi-protocol access to the...

Summary: NetBIOS offers communication services between applications and computers on local networks. Look here to learn insight about NetBIOS - Network Basic Input/Output System. Definition Of NetBIOS Standing for Network Basic Input/Output System, NetBIOS is a networking industry standard developed by IBM, Microsoft, and Sytek. It is currently mostly used by Microsoft Windows operating systems to provide certain services to the other network hosts. NetBIOS provides services associated with the OSI model's session layer, allowing applications on different computers to communicate over the local network. It also allows the proper transmission of data over the network. NetBIOS typically communicates on ports 137, 138, and 139. History Of NetBIOS In 1985, IBM first created the NetBIOS protocol for use in Microsoft's Windows operating system. In 1985, Microsoft implemented NetBIOS for MS-Net network technology. In 1986, Novell published the Advanced Novell NetWare 2.0, which features its own NetBIOS emulator. In 1987, a method called NetBIOS over TCP/IP (NBT) was published to encapsulate NetBIOS in TCP and UDP packets. In 1987, after the PS/2 computer went on sale, IBM released a PC LAN Support Program that included a driver for NetBIOS. Since its original publishing in a technical reference book from IBM, the...

Summary: Have you heard TTL? It dictates how long to cache the query or content. This article will show you more detailed information about time to live (TTL). What Is TTL? Time to live (TTL), also known as hop limit, is a mechanism that limits the lifetime or lifespan of data on a computer or network. It refers to the time or "hops" that a packet will exist within the network before being dropped by a router. TTL determines how long the computer refreshes its DNS related information. It can be implemented as a timestamp or counter attached to or embedded in data. Once the specified period or event count has passed, the data is discarded or re-validated. In computer networking, TTL prevents packets from looping indefinitely. In computing applications, TTL is typically used to improve performance and manage data caching. How Does TTL Work? The primary function of TTL is to manage packets of information related to DNS requests. When users create and send a packet of information over the Internet, it may continue to pass the information from the router to the router indefinitely. The packet is designed with expiration to reduce this possibility, which is called the...

Summary: Real-Time Operating System (RTOS) is one of the most important components in today's embedded systems and takes responsibility for everything from scheduling tasks to enable advanced languages. So this article will give a full introduction to RTOS. Definition RTOS, short for real-time operating system, is an operating system (OS) designed to serve real-time applications that process data input without buffer delays. Processing time requirements, including any operating system latency, are measured in tenths of a second or less. A real-time system is a time-bound system with a well-defined fixed time limit. In such a system, processing must be done within the specified constraints. Otherwise, the system will fail. They are either time-sharing or event-driven. The time-sharing system switches tasks based on clock interrupts, while the event-driven system switches tasks based on task priority. Components RTOS consists of multiple essential components. Fast dispatch latency: It's an interval between the end of the task, which can be identified by the OS, and the actual time taken by a thread. Function Library: As an important element of RTOS, it acts as an interface to connect kernel and application code. This application enables users to use the library to send requests to the...

Summary: If you're not sure about the operating system bit count (32-bit or 64-bit) for Windows 10 that your PC is running, this article will be available to you. We'll show you straightforward ways to check whether your PC is running 32-bit or 64-bit Windows 10. Difference Between 32-bit And 64-bit The terms 32-bit and 64-bit of Windows refer to how a computer processor (CPU) processes information. The 64-bit version handles large amounts of RAM(Random Access Memory) more efficiently than the 32-bit version. The System Type shows whether you are running a 32-bit version or a 64-bit version of Windows 10. It also shows you if your computer is compatible with the 64-bit version. The 32-bit operating system processor means you're using a 32-bit version of Windows 10. But you can install a 64-bit version on your hardware if you want. The 64-bit operating system processor indicates that you are using a 64-bit version of Windows 10. Simply put, your computer should have a 64-bit processor to run the 64-bit version of Windows. A 64-bit can run 32-bit applications, but a 32-bit version can't run 64-bit software. Methods To Check Whether The PC Is Running 32-bit Or 64-bit Method 1:...
