    Laser printers use ............ printing technology

    Explanation
    Laser printers use electrophotographic printing technology. This technology involves a complex process where an electrostatic image is formed on a photosensitive drum or belt by selectively charging areas with a laser beam. The charged areas attract toner particles, which are then transferred to paper and fused using heat and pressure. This method allows for high-quality and fast printing, making laser printers popular in various settings such as offices and homes.

    ......... is a attack that randomly opens TCP ports.

    Explanation
    A Syn flood is an attack where the attacker sends a large number of TCP SYN requests to a target server, but does not complete the handshake process by sending the final ACK packet. This causes the server to keep the connection half-open, consuming server resources and eventually leading to a denial of service. As the attack is random and aims to overwhelm the server with incomplete connections, it is an effective method to disrupt network services.
