Netware Core Protocol


Netware Core Protocol (NCP) is a network protocol used primarily in Novell NetWare operating systems for network-related services, such as file access and printer access. It operates at the application layer of the OSI model, allowing clients to make requests of a server and facilitating the server’s responses. NCP serves as the basis for client/server interactions in NetWare systems.


The phonetic pronunciation of “Netware Core Protocol” is:Netware: /ˈnɛtˌweər/Core: /kɔːr/Protocol: /ˈproʊtəˌkɑːl/

Key Takeaways

Sure, here are three main takeaways about Netware Core Protocol (NCP):“`html

  1. NCP is a protocol that supports the Client-Server architecture. It hosts numerous services such as harmonizing requests for file and print services to a remote server over a network.
  2. It functions in a way that the clients are not obligated to know the structure of the network they are functioning on. Consequently, this allows for flexibility in the application structure and location of the network resources.
  3. Primarily used in NetWare operating systems, NCP presents a high level of security and performance, making it a reliable choice for accessing shared network services.



Netware Core Protocol (NCP) is an essential term in technology as it pertains to the networking concept, particularly that of Novell NetWare operating systems. NCP is the protocol which governs the client-to-server interactions and provides a wide range of services like file management, connection management, printer servicing, and more. As a networking protocol, NCP plays a significant role in maintaining efficient data transmissions between various devices and servers within a network, ensuring smooth and reliable network operations. Its importance also lies in its support for multiple simultaneous connections and requests, thereby promoting multi-tasking and enhancing overall system productivity.


The NetWare Core Protocol (NCP) plays a critical role in computer networking as it is primarily employed for creating a connection and facilitating communication between servers and clients in a network system. Developed by Novell for its NetWare operating system, NCP is responsible for an array of network services including file sharing, printer access, and server management. It encompasses numerous tasks such as managing file access, handling directories, governing printers, broadening administration practices, and more, thereby ensuring seamless and efficient network operations.The purpose of NCP extends beyond forming connections, as it also offers concurrent functionalities to ensure a secured and user-friendly environment. It supports multiple connections from a client to a server, allowing different tasks to run simultaneously without interrupting each other. Moreover, it emphasises security measures, as it requires client authentication at login, ensuring that only approved users can access network resources. In summary, NCP’s primary function is to deliver a reliable, efficient, and secure medium for client-server interactions within a network, enabling effective sharing and management of resources.


NetWare Core Protocol (NCP) is a network protocol used in Novell NetWare operating systems to provide services such as file access, record locking and file notification.1. Print Servers: Previous editions of Novell NetWare used NCP protocol in print servers, allowing multiple machines in a network to share a single printer. The NCP protocol handled the communication between the client computer and the network printer, thus ensuring the smooth operation of printing tasks.2. File Sharing and Data Management: NCP enabled file sharing and management on a network. For example, in a corporate setting where multiple employees are working across different workstations, NCP enabled consistent and reliable access to shared files and allowed for the management of these files.3. Email and Messaging Systems: In Novell GroupWise, an email and messaging system, NCP was often used for client-server communication. The protocol was instrumental in the delivery, storage, and synchronization of emails across a network of systems, highlighting NCP’s role in facilitating efficient communication within a business setup. It’s important to note though that these examples are mostly from legacy systems as modern networks have largely moved on from NetWare and NCP.

Frequently Asked Questions(FAQ)

Q: What is Netware Core Protocol (NCP)?A: Netware Core Protocol (NCP) is a network protocol used in Novell NetWare operating systems that gives users and applications access to services such as file and printer sharing on a network.Q: How does NCP function?A: NCP functions by searching for services hosted on servers on a local network. It communicates with the servers to access their services, such as file sharing and network-based print spooling.Q: What operating system is NCP associated with?A: NCP is associated with Novell NetWare, a network operating system that was commonly used in the late 1980s and 1990s.Q: Is NCP still used today?A: While it’s been largely phased out in favor of newer networking protocols, NCP is still used in some legacy systems. Most modern systems use protocols such as TCP/IP.Q: Can NCP work with TCP/IP?A: Yes, NCP can work with TCP/IP, using a system known as Novell’s NetWare/IP.Q: Are there any prominent security features in NCP?A: NCP uses access control lists and the Bindery or NetWare Directory Services for securing network access.Q: What services does NCP provide?A: NCP provides several network services, including file sharing, printer access, messaging, and job handling.Q: Is it difficult to configure NCP?A: As with any networking protocol, configuration can be complex and requires some understanding of networking concepts. However, many find configuring NCP less complex than more modern systems like TCP/IP.
