OSI Model By Amjad, Rimsha Safi Ullah And Iqra
The document discusses the Open Systems Interconnection (OSI) model created by the International Organization for Standardization. The seven-layer OSI model provides a standard for how different networking technologies can communicate. It describes the functions of each layer, including physical transmission of bits, error-free delivery of data, routing packets across networks, reliable end-to-end message transport, session synchronization, data formatting, and providing applications and services to users.
Viloria osi layer4-7
The document discusses the Open Systems Interconnection (OSI) reference model, which introduced standards for network communication. The OSI model organizes network functions into seven layers, with each layer building on the services provided by the previous layer. Layers 1-4 deal with flow of data through the network, while layers 5-7 deal with services for applications. The model helps ensure compatibility between different network technologies.

Topic 5- Communications v1.pptx
The document discusses communication in distributed systems. It covers topics like layered protocols using the OSI reference model, transport layer protocols like TCP and UDP, middleware protocols that provide common services, client-server communication using TCP connections, push vs pull architectures, types of communication like persistent vs transient and synchronous vs asynchronous, and remote procedure calls (RPCs) that allow remote functions to be called like local procedures.
Remote procedure calls
Remote Procedure Calls (RPC) allow clients and servers to communicate by extending the concept of local procedure calls so that the called procedure need not exist in the same address space. RPC uses message passing and stubs to conceal the underlying communication and make remote calls appear local. The RPC model involves a client, client stub, RPC runtime, server stub, and server. Stubs handle packing arguments, sending requests, and returning results to maintain transparency.
Osi

slides.06.pptx
Distributed Systems (3rd Edition) Chapter 06 discusses coordination through clock synchronization and logical clocks. It describes several clock synchronization algorithms like Network Time Protocol that aim to keep physical clocks precise and accurate. Logical clocks like Lamport's logical clocks attach timestamps to events in a way that preserves causality without a global clock. Vector clocks were developed to guarantee causal precedence between timestamps. Total-ordered multicast uses logical clocks to ensure all processes see messages in the same order.
slides.07.pptx
Distributed systems often replicate data across multiple servers for performance and reliability. To keep replicas consistent, conflicting operations like write-write must be ordered the same everywhere. However, guaranteeing a global order is costly and hurts scalability. Weaker consistency models address this by relaxing the consistency requirements. Client-centric models like monotonic reads and writes ensure users see their own updates regardless of which server they access.

The goal is to introduce different approaches to structuring distributed systems and classify them based on architectural patterns.
chapter1.ppt
This lecture introduces distributed systems, defining them and providing examples. It outlines the goals of distributed systems including transparency, scalability, and openness. It discusses techniques for scaling distributed systems like hiding communication latencies, asynchronous communication, distribution, replication, and caching. Finally, it summarizes the key topics covered in the lecture.
Ch 1-Non-functional Requirements.ppt
This document discusses non-functional requirements (NFRs) including definitions, classifications, and examples. It describes how NFRs define overall system qualities and constraints. Common NFR classifications include product requirements, organizational requirements, and external requirements. Examples of specific NFRs are provided like availability, reliability, usability, and maintainability. Conflicts can occur between NFRs that must be addressed. The document provides an overview of approaches to defining, analyzing, and testing NFRs.
Ch 6 - Requirement Management.pptx
This document discusses requirement management and outlines several key activities:
1. It distinguishes between stable and volatile requirements and different types of volatile requirements.
2. It describes requirements management activities like change control, version control, and requirements tracing.
3. It emphasizes that requirement management is an ongoing process that involves identifying, storing, and tracking changes to requirements throughout the project life cycle.

A Study of Variable-Role-based Feature Enrichment in Neural Models of Code
Understanding variable roles in code has been found to be helpful by students
in learning programming -- could variable roles help deep neural models in
performing coding tasks? We do an exploratory study.

Hand Rolled Applicative User Validation Code Kata
Could you use a simple piece of Scala validation code (granted, a very simplistic one too!) that you can rewrite, now and again, to refresh your basic understanding of Applicative operators <*>, <*, *>?
The goal is not to write perfect code showcasing validation, but rather, to provide a small, rough-and ready exercise to reinforce your muscle-memory.
Despite its grandiose-sounding title, this deck consists of just three slides showing the Scala 3 code to be rewritten whenever the details of the operators begin to fade away.
The code is my rough and ready translation of a Haskell user-validation program found in a book called Finding Success (and Failure) in Haskell - Fall in love with applicative functors.
