Output devices
An output device accepts data from a computer and translates it into a form suitable for the outside world. There are two main types of output: soft copy, which is temporary, and hard copy, which is permanent and printed onto paper or other material. Printers are commonly used today to produce hard copy output. Dot matrix printers print one character at a time using pins that strike an ink ribbon to form dots, while inkjet printers spray small ink drops to form characters and images at high resolution but slower speeds. Laser printers use a laser beam to fuse tiny ink particles onto paper for very high quality output.

Hello there, this powerpoint presentation is made by Ansh kashyap(me) the topic of this presentation is "Output devices".
An output device is any piece of computer hardware equipment which converts information into a human-perceptible form or, historically, into a physical machine-readable form for use with other non-computerized equipment. It can be text, graphics, tactile, audio, or video.
printers
There are two main types of printers: impact printers and non-impact printers. Impact printers work by physically striking an inked ribbon against the paper, and include dot-matrix, daisy wheel, drum, chain, and band printers. Non-impact printers do not physically strike the paper, and include inkjet printers which spray ink onto paper, and laser printers which use a laser beam to attract toner onto the paper to form images. Dot matrix printers use print heads with pins that form characters by striking individual dots, while laser printers use a laser beam and toner to efficiently print high quality pages at speeds up to 437 pages per minute.

Belgium coach Domenico Tedesco will wait for several key players to recover from injury. Even if it means they miss the opening Euro Cup Germany stages of the European Championship in Germany this month. Veteran defender Jan Vertonghen, midfielder Youri Tielemans and defender Arthur. Theate are being given time to play in the tournament because they are considered vital to Belgium’s cause, Tedesco said on Tuesday.

"Of course, you prefer to take players who are fully fit, but that's okay. We want to wait and be patient for some players even if they cannot play in those first matches," he told a press conference. The 37-year-old Vertonghen, Belgium’s Euro Cup 2024 most-capped international with 154 appearances, is struggling to shake off a groin injury.
"He will be there normally. This also applies to Youri Tielemans and Arthur Theate. The latter's position is very sensitive. We don't have many choices at left back. "It will only change if it turns out that they will only be available when, say, the final of the Euro 2024 Championship comes around. That's too long to wait.

Belgium vs Romania: Radu Dragusin Prepares for Crucial Role in Euro Cup Germany
Some of them have taken not one but two steps forward in their rehabilitation," he said. None of the injured players will feature in this week’s warm-up friendlies against Montenegro and Luxembourg. Romania centre-back Radu Dragusin found chances limited at Tottenham Hotspur in the second half of the 2023-24 season.
But is crucial to his country's cause at UEFA Euro 2024 where his aerial ability, physicality and hard graft make him a standout player. The 22-year-old moved to North London from Italian side Genoa in January but was kept on the sidelines by the form of another new arrival for the season, Mickey van de Ven, something Romania coach Edward Iordanescu admitted was a concern.
It will mean limited game-time going into the finals, but Dragusin, who cites Netherlands defender Virgil van Dijk as a role model, started every Euro Cup Germany qualifier as Romania went through the campaign unbeaten in their 10 games. He will be among their most important players in their first game in Germany against Ukraine in Munich on June 17, taking the right centre-back role in what is likely to be a back four.

As well as being the highest-scoring defender in history, Koeman is a man with immense tactical knowledge. He returned to manage Holland at the start of 2023 after it was announced Louis van Gaal would retire. His life back in the dugout with the team wasn't easy, as he lost his first match 4-0 to France after going 3-0 down within 21 minutes.

Psaroudakis: Family and Football – The Psaroudakis Success Story
Psaroudakis, a name that resonates with football fans around the globe, is a testament to the powerful synergy between familial support and individual passion. Born on March 10, 1992, in the historic city of Heraklion, Crete, Psaroudakis’ journey to international football stardom is a compelling narrative of dedication, perseverance, and unwavering family support. His story not only highlights his athletic prowess but also underscores the crucial role his family played in shaping his career and character.
Psaroudakis’ early life in Heraklion was deeply influenced by a supportive and nurturing family environment. His father, a former semi-professional footballer, recognized Psaroudakis’ potential from an early age. Acting as his first coach, his father’s guidance was instrumental in igniting Psaroudakis’ passion for football. This paternal influence instilled in him a strong work ethic and fundamental skills that would become the foundation of his future success. His mother, a dedicated homemaker, provided a stable and nurturing environment, ensuring that Psaroudakis could pursue his dreams without any hindrances.
From a young age, Psaroudakis showed an innate talent for football. Growing up in Heraklion, he spent countless hours playing football in local parks and streets with friends and family. His natural ability was evident even in these informal settings, and his enthusiasm for the game was infectious. By the age of five, Psaroudakis had joined a local youth football club, where his skills began to flourish. His father’s role as his first coach during these formative years was crucial, as he emphasized not only technical skills but also the importance of discipline and teamwork.
The transition from playing in local parks to joining a structured football environment marked a significant step in Psaroudakis’ journey. At the age of ten, he joined the youth academy of OFI Crete, one of Greece’s most esteemed football clubs. This move marked the beginning of a more rigorous and professional approach to his training. The academy environment was demanding, focusing on honing technical abilities and instilling values of sportsmanship and dedication. Psaroudakis’ dedication to his craft was evident as he quickly rose through the ranks, becoming a standout player in the youth teams.
The support of Psaroudakis’ family was unwavering during this critical period. His father continued to be a source of guidance and mentorship, while his mother ensured that he had everything he needed to succeed. Their collective efforts created a balanced environment where Psaroudakis could focus entirely on his development as a footballer. This familial support was not just about providing the basics; it was about creating an environment where Psaroudakis felt encouraged and motivated to pursue his dreams relentlessly.
As Psaroudakis transitioned from the youth academy to professional football, the challenges became more significant.
