Step-by-step explanation:
Traditional and computerized roll-call votes are often used for various reasons.
Traditional roll-call votes, such as mechanical voting machines and punch-card machines, have been used for decades. They provide a physical record of the voter's choice and can be used in recounts. However, they have their drawbacks, such as machine breakdowns and issues with vote counting.
Computerized roll-call votes, such as touch-screen machines and robo-polls, offer convenience and efficiency. They eliminate the need for physical ballots and can provide quick and accurate results. However, these methods have their own set of problems, including security vulnerabilities and potential errors.
