CRT monitors use electron guns to shoot electrons at phosphor particles to display an image, but they are heavy, emit radiation, and cause eye strain. TFT monitors use thin film transistors and liquid crystals to display each pixel and are lighter and cause less eye strain. Laser printers use toner and an electrically charged drum to produce high-quality, fast outputs while inkjet printers produce high-quality color prints but are slower. Dot matrix printers use pins and ink ribbons for noisy, multi-copy printing. Plotters can produce large, high-quality graphics and blueprints using pens or inkjets. Speakers output sound files from computers.

Devices that output hard copy
An external hardware device responsible for taking computer data and generating a hard copy of that data. Printers are one of the most commonly used peripherals and they print text and still images on the paper.
Impact printers use a device to strike an inked ribbon, pressing ink from the ribbon onto the paper.
Non-impact printers use different methods to place ink (or another substance) on the page.
(1) DPI:
It is a measurement of printer’s resolution indicating how many ink dots can be placed by the printer in one square inch. The higher the DPI, the sharper is image. Image quality – Measured in dots per inch (dpi). Most printers produce 300 – 1200 dpi.
(2) Type of printer:
Each type of printer has its own capabilities of printing. Some types of printers produce high quality print while other produce low quality print.
(3) Print Mode:
The printing mode may also affect the quality. For example the draft mode increases the print rate but quality is reduced.
(4) Toner:
The quality and amount of toner also affects print quality.
The Output Devices of computer system are electromagnetic devices or gadgets that accepts or acknowledge data or informations from computer system and translate and converts the data in human readable or intelligent form. Generally output can be obtained and acquire mainly in two distinct and different ways Softcopy and Hardcopy.At the point when handled data or information is stored in computer memory is given to an output unit then this processed or prepared data or information is displayed to user in such a way that they can easily read

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
The Art of the Pitch: WordPress Relationships and SalesLaura Byrne
Clients don’t know what they don’t know. What web solutions are right for them? How does WordPress come into the picture? How do you make sure you understand scope and timeline? What do you do if sometime changes?
All these questions and more will be explored as we talk about matching clients’ needs with what your agency offers without pulling teeth or pulling your hair out. Practical tips, and strategies for successful relationship building that leads to closing the deal.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
4. CRT Monitors
• CRT stands for cathode ray tubes.
• Despite the fact that it is the cheapest monitor available it is becoming
less popular.

particles.
They are used in environments where space is not an issue.

called LCD’s. LCD stands for liquid crystal display.
• The screen consists of thousands of miniature transistors. These
transistors are activated by the processor. Each pixel is formed from
RGB (Red, Green and Blue).
• Used when only 1 person needs to see the screen.

6. Laser Printers
× High quality hard copies are produced.
How does it work?
Laser changes the charge on the drum for each dot.
Electrically charged toner is attracted to the oppositely charged
dots.
The paper then presses against the toner-coated drum
This then outputs with the pattern of dots required.
Page is only printed after whole documents has been stored in

• Ink is forced out of a nozzle directly onto the paper.
• Weighs less than a laser printer
• Printout is produced little by little as it receives the signals from the
computer.
• They are especially useful in those places where high quality is required
and speed is not an issue.
Advantages Disadvantages
High quality printout They are slow if you need to print
more than one page.
Fast if you are only printing one More expensive to run because the
page ink cartridges don’t last very long.
