OSI Reference Model and TCP/IP (Lecture #3 ET3003 Sem1 2014/2015)
This document provides an overview of the OSI model and TCP/IP protocol suite for computer networks. It describes the seven layers of the OSI model from the physical layer to the application layer and their functions. It then explains that while the OSI model was intended as a standard, TCP/IP became dominant in practice.

The application layer combines functions from several OSI layers.
TCP/IP Model
The TCP/IP model has four layers: Application layer, Transport layer, Internet layer, and Network Access layer. The Application layer contains protocols that provide services to users like web browsing, email, and file transfers. The Transport layer deals with manipulating data and preparing it for delivery through the network using protocols like TCP and UDP. The Internet layer determines routing and addresses using IP addressing and routing protocols. The Network Access layer is responsible for transmitting bits and bytes across physical network connections using devices like hubs, switches, and network interface cards.

The document discusses network models and compares the OSI model and TCP/IP model. It provides details on the layers of the OSI model including the 7 layers from physical to application layer. It describes the functions of each layer such as physical dealing with raw bit transmission, data link framing bits into frames, network routing packets, transport ensuring reliable data delivery, session controlling connections, presentation translating between systems, and application providing user interfaces. It also summarizes the similarities and differences between the OSI and TCP/IP models.
Lecture 1 networking & internetworking
This document provides an overview of networking and internetworking concepts. It defines what a network is and some common network protocols like TCP/IP. It discusses how network speed is measured by bit rate and latency. It then covers local area networks, wide area networks, and the internet. The document explains the purpose of networks for file sharing, communication, and remote program execution. It also discusses network messaging and different network service models like the OSI reference model and TCP/IP model. Finally, it provides a simplified example of how the TCP/IP protocol functions to route a packet from a source to destination across multiple routers.
Ccna notes
The document provides information about the CCNA certification options and Cisco networking concepts including the OSI model. It can be used to study for the CCNA exam. There are two options to obtain the CCNA: pass a single exam or two exams.

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
