A Network Addressable Unit (NAU) refers to a component in IBM’s Systems Network Architecture (SNA) that can be accessed by name and address. This includes System Services Control Point (SSCP), Logical Units (LU), and Physical Units (PU).
In simpler terms, a NAU is a component that can be given an address and can send and receive data within a SNA network.
Key Points:
- NAUs are part of IBM’s Systems Network Architecture (SNA).
- Examples of NAUs include System Services Control Point (SSCP), Logical Units (LU), and Physical Units (PU).
- NAUs can be accessed by their name and address within a SNA network.
- A NAU is a component that can send and receive data.
Frequently Asked Questions:
What is IBM’s Systems Network Architecture (SNA)?
IBM’s Systems Network Architecture (SNA) is a proprietary networking architecture developed by IBM in the 1970s. It provides a framework for connecting mainframe computers and other devices.
What is a System Services Control Point (SSCP)?
A System Services Control Point (SSCP) is a component in IBM’s SNA that provides centralized control and management of network resources. It manages the routing and coordination of data between NAUs.
What is a Logical Unit (LU)?
A Logical Unit (LU) is a component in IBM’s SNA that represents a network application or program. It is responsible for processing and exchanging data with other LUs on the network.
What is a Physical Unit (PU)?
A Physical Unit (PU) is a component in IBM’s SNA that represents a physical device, such as a mainframe computer or terminal, which can send and receive data on the network.
By understanding the concept of Network Addressable Units (NAUs), you can gain insight into how IBM’s Systems Network Architecture (SNA) functions and how different components interact within the network.
