Encryption uses VPNs, WANs, routers, and firmware to securely transmit information over networks. A VPN creates a private network using open connections in a larger network instead of physical wires. A WAN is a wireless network that connects broad areas using routers and public communication links. Routers direct network traffic and information along different paths. Firmware is software installed directly into equipment to control hardware functions and exists as an intermediary between hardware and software.

There are several types of computer networks including personal area networks (PANs), local area networks (LANs), wide area networks (WANs), wireless local area networks (WLANs), and metropolitan area networks (MANs). Network analysis involves capturing and inspecting network traffic to determine what is happening on the network and ensure security.
Computer networking
A computer network connects two or more computers together using common communication protocols and digital interconnections to share resources. It allows for communication and data sharing that enables businesses, entertainment, and research. Computer networks consist of networking hardware like routers, hubs, servers, switches and bridges. Networking software helps administer, manage and monitor the network. Cables and connectors are used to physically connect the networking hardware devices.

Networks
A network is a system that connects computers to share resources and exchange data. Common network types include LANs which connect nearby devices via cables, and WANs which connect multiple LANs across wide areas. Hybrid networks like CANs and MANs combine aspects of LANs and WANs. Networks are structured with servers that control access to shared resources, or in peer-to-peer structures with equal sharing between nodes. Topologies determine how nodes are physically connected, such as in a bus, star, ring, or mesh configuration. Protocols define rules for data transmission between devices on the network.

Freshworks Rethinks NoSQL for Rapid Scaling & Cost-Efficiency
Freshworks creates AI-boosted business software that helps employees work more efficiently and effectively. Managing data across multiple RDBMS and NoSQL databases was already a challenge at their current scale. To prepare for 10X growth, they knew it was time to rethink their database strategy. Learn how they architected a solution that would simplify scaling while keeping costs under control.
Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

Next, let's discuss package managers. Package managers play a critical role in the OSS ecosystem. I'll explain how to manage library dependencies in your application.
I'll share insights into how the Ruby and RubyGems core team works to keep our ecosystem safe. By the end of this talk, you'll have a better understanding of how to safeguard your code.
Essentials of Automations: Exploring Attributes & Automation Parameters
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.

How Enryption for Strong Security Works
- 1. How Encryption for Strong Security Works 1. VPN 2. WAN 3.Router 4. Firmware
- 2. VPN A virtual private ● network (VPN) is a computer network in which some of the links between nodes are carried by open connections or virtual circuits in some larger network instead of by physical wires.
- 3. WAN WAN is wide area ● network. It is a computer network that covers broad area. Less formally, a Wan is a wireless network that uses routers and public communications links.
- 4. Router A router is a ● networking device whose software and hardware are usually tailored to the tasks of routing and forwarding information. For example, on the Internet, information is directed to various paths by routers.
- 5. Firmware Software built into equipment to do basic control of hardware. It is called the firmware from installing in the equipment fixing, and no so much addition of the change as intermediate existence of hardware and software.
