Yes, it is. A web service is a specific implementation of RPC. At its lowest level, Web Service connects to the Socket, using the HTTP protocol, to negotiate sending a payload that is executed in a remote space (remote space can be the same computer). All these remote call abstractions, at its core, are RPCs.

• Data is formatted for transfer using XML, improving or eliminating marshalling, unmarshalling, and various other translation-related requirements normally coded by a developer. 
• Data is passed using standardized protocols such as HTTP or SMTP, which have published well-defined standards. 
• The underlying exposed service is well-defined using a known accepted mechanism, WSDL. 
• Services are found using a well-defined standard, UDDI, and the more advanced ebXML. 

Specifically WSDL provides a number of key pieces of information:

• A definition of the format of the messages that are passed between two endpoints using its and elements and appropriate schema definitions. 
• The semantics of the service: how it might be called to make a synchronous request/reply, synchronous reply-only or asynchronously communicate. 
• The end point and transport of the service via the element: that is, who provides the service. 
• An encoding via the element, that is how the service is accessed.

blocks|key|3252818|text|远程过程调用(RPC)和WebService在功能上是并行的。但它们的调用方式有一个细微的差异。Web服务可以由任何应用程序调用，使用HTTP协议上的XML格式进行处理，并且其本质上是可互操作的，而在RPC的情况下，该函数可以由多个应用程序调用，因此它遵循序列化的路径来存储对象数据。它支持TCP协议上的二进制格式。在一种更好的方法中，我们可以简要介绍RPC工作流程，就像我们通过适当的套接字和适当的消息格式执行函数，但不知道客户端server.Even中特定函数的实际存在提供的套接字可能不在函数所在的同一服务器中。但每次它都给人一种函数位于局部的感觉。在远程服务中，函数驻留在远程机器上，可以通过适当的格式和协议调用，并且具有可扩展性。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3252819|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Remote Procedure Call (RPC) and WebService, in the sake of Functionality both go parallely. But there is a subtle difference in their way of invoking. 
An Web Service can be invoked by any application, using XML format over HTTP protocol for proceedings and its interoperable in nature, whereas in case of RPC the function can be Invoked by multi applications so it follow the path of Serialization to store the object data. It supports Binary Format over TCP protocol.
In a better approach we can brief RPC workflow, like we are executing a function through proper Socket and proper format of message, but don't know the actual existence of the particular function in client server.Even the provided socket might not be in the same server in which the function resides. But every time it give a feel like the function is located in the local. In Remote Service, the Function resides in remote machine and it can be invoked by proper format and Protocol and it allows Scalability.

I see this question. The question has been asked long time ago, but I think anyone's answer in this community, giving more information and clarity on this topic, will be helpful for the future questioners. So, I would like to add my enhancement pointing out key differences and I hope, it will be helpful for future readers.

I have not mentioned descriptions of RPC and Web Services, because you see them in others' answer clearly.

Is there any clear definition of RPC and Web Service? A quick wikipedia search shows:

<blockquote>
 RPC: Remote procedure call (RPC) is an
 Inter-process communication technology
 that allows a computer program to
 cause a subroutine or procedure to
 execute in another address space
 (commonly on another computer on a
 shared network) without the programmer
 explicitly coding the details for this
 remote interaction. 
 
 Web Service: Web services are
 typically application programming
 interfaces (API) or web APIs that are
 accessed via Hypertext Transfer
 Protocol and executed on a remote
 system hosting the requested services.
 Web services tend to fall into one of
 two camps: Big Web Services[1] and
 RESTful Web Services.
</blockquote>

I am not quite clear what the real difference between the two things. It seems that one thing could belong to RPC and is kind of web service at the same time.

Is Web Service a higher level representation of RPC?

What is the difference between remote procedure call and web service?
