Open Systems Interconnection
The OSI model is a conceptual framework that characterizes computing functions into a set of rules to support interoperability between networking systems. It divides network communication processes into seven smaller layers - physical, data link, network, transport, session, presentation, and application layer. Each layer has a specific role like the physical layer deals with transmission of raw bits, the network layer handles routing between devices, and the application layer supports programs that use the network. The model allows networks with different hardware and software to communicate in a standard way.

LANs connect computers within a small area like a building using technologies like Ethernet. PANs connect personal devices within 30 feet of an individual. MANs interconnect multiple LANs within a larger area like a city using technologies like Frame Relay. WANs extend over large geographical areas like states or countries using technologies like fiber optic cables and satellites.

Satellites
Satellites orbit Earth in different types of orbits depending on their purpose. Low Earth orbit satellites like those used for scientific research fly only a few hundred kilometers above Earth and complete an orbit in 90 minutes, allowing them to observe different parts of the planet. Medium Earth orbit satellites, including GPS satellites, fly around 20,000 km above Earth and take 12 hours to orbit. High Earth orbit satellites like communications and weather satellites fly at 36,000 km, taking one day to orbit so they remain stationary over one location on Earth.

Topology
This document discusses different network topologies including physical and logical topologies. It describes various common topologies such as bus, ring, star, tree, mesh, and hybrid topologies. For each topology, it provides details on how the nodes are connected and arranged, common examples, and characteristics such as direction of data flow or access methods.
Network Cables
This document discusses the three main types of network cables: fiber optic cable, twisted pair cable, and coaxial cable. Fiber optic cable transmits messages modulated onto light waves through bundles of glass threads. It has a complicated design involving single-mode or multi-mode configurations of the core. Twisted pair cable is ordinary copper wire connecting homes and businesses to telephone companies. The wires are twisted to reduce crosstalk. Coaxial cable carries data through a central conductor surrounded by insulating layers and shielding to prevent signal loss and reduce electromagnetic interference.

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.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

- 3. Computer Network A computer network is a set of devices connected through links. A node can be computer, printer, or any other device capable of sending or receiving the data. The links connecting the nodes are known as communication channels. •Computer Network is a group of computers connected with each other through wires, optical fibres or optical links so that various devices can interact with each other through a network. •The aim of the computer network is the sharing of resources among various devices. •In the case of computer network technology, there are several types of networks that vary from simple to complex level.
- 4. Components Of Computer Network Computer network components are the major parts which are needed to install the software. Some important network components are NIC, switch, cable, hub, router, and modem. Depending on the type of network that we need to install, some network components can also be removed. For example, the wireless network does not require a cable.
- 5. NIC •NIC stands for network interface card. •NIC is a hardware component used to connect a computer with another computer onto a network •It can support a transfer rate of 10,100 to 1000 Mb/s. •The MAC address or physical address is encoded on the network card chip which is assigned by the IEEE to identify a network card uniquely. The MAC address is stored in the PROM (Programmable read-only memory).
- 6. Graduate Record Examinations Value of Using GRE Scores Scores Support Institutions' Efforts to Identify Which Applicants Are Academically Prepared for Graduate-level Study. Scores Provide a Common, Objective Measure to Help Programs Compare Applicants from Different Backgrounds. Important Considerations The Scores Do Not and Cannot Offer Insight Into All of the Qualities that Are Important In Predicting Academic Success or In Confirming Undergraduate Achievement. The Scores Need to Be Interpreted Carefully Because, Like All Tests, They Are Not Exact Measures.
