Lecture 1 an introduction to computer networks
This document provides an introduction to computer networks. It defines data communication as the exchange of data between two devices via transmission medium. It presents a simplified data communication model including the message, sender, medium, receiver, and protocol. It explains that point-to-point communication is not practical for distant or large sets of devices, so a communications network is used instead. Networks allow for better connectivity, communication, sharing of resources, and overcome geographic limits to access remote data with the goal of universal communication between any devices. Networks can also be classified based on transmission media, size, management method, and topology.
Networking Fundamentals
This document provides an introductory lecture on computer networks by Shahzad Ali. It defines what a network is and discusses different types of computer networks including personal area networks (PAN), local area networks (LAN), metropolitan area networks (MAN), and wide area networks (WAN). The document also covers network design topics such as client-server and peer-to-peer networks, common network topologies (bus, ring, star, mesh), network protocols, and whether networks are wired or wireless. It provides examples and details for each topic.
Network Resources
A network physically connects computers and devices that exchange data through wires or wireless transmission. Devices like routers and switches direct traffic to improve the flow of data across the network. There are two main types of networks: local area networks (LANs) that connect devices over short distances like within an office or school, and wide area networks (WANs) that connect devices over large distances like the Internet. While LANs are typically owned by a single entity, WANs use shared public infrastructure. Networks can be wired or wireless, with wireless networks becoming more common and allowing access from any location.
Network Types and Topologies
A computer network connects multiple computers together allowing sharing of resources. There are two main types: local area networks (LANs) covering a small area like a school, and wide area networks (WANs) spanning large geographical areas like the internet. Network topologies determine how devices are physically connected - a bus network uses one cable, a ring network forms a continuous loop, and a star network connects each device to a central hub/switch. Networks provide advantages like shared printing and internet access but also have costs and potential single points of failure.

Common network types are LANs for local connections and WANs for wide area connections between locations. Protocols like TCP/IP are used to allow communication between different computers and networks. Ethernet is a common standard for LAN connections using cables like twisted pair or fiber optic.

A computer network is a digital telecommunications network that allows network nodes to share resources. In computer networks, computer devices exchange data with each other using connections (data links) between nodes. These data links are established via network cables such as wire or fiber optics , or wireless media such as Wi-Fi .
Network computing devices that launch, route , and terminate data are called network nodes. [1] Nodes are often identified by network addresses and can include network hosts such as personal computers , phones , and servers , as well as network hardware such as routers and switches. Two such devices can be said to be interconnected when one can exchange information with the other, whether they are directly connected to each other or not. In most cases, application-specific communication protocols are layered (i.e., carry a payload ) over other general communication protocols . This formidable collection of information technology requires skilled network managers to keep all network systems running well.
Types of Computer Networks bba 1st sem.pptx
There are various types of computer networks available. We can categorize them according to their size as well as their purpose.
The size of a network should be expressed by the geographic area and number of computers, which are a part of their networks. It includes devices housed in a single room to millions of devices spread across the world.
Some of the most popular network types are:
PAN
LAN
MAN
WAN
Computer network
A computer network consists of two or more computers that are linked in order to share resources such as printers and CD-ROMs, exchange files, or allow electronic communications. The computers on a computer network may be linked through cables, telephone lines, radio waves, satellites, or infrared light beams.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
National Security Agency - NSA mobile device best practices
Threats to mobile devices are more prevalent and increasing in scope and complexity. Users of mobile devices desire to take full advantage of the features
available on those devices, but many of the features provide convenience and capability but sacrifice security. This best practices guide outlines steps the users can take to better protect personal devices and information.
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.
