He points out how different Othello and Desdemona are: he's had a rough and tumble life and she's been a sheltered rich girl, he's grown up all over the place and she's spent her life in Venice, he is old and she is young, he is black and she is white. On the other hand, Cassio is the same age, the same colour, and from the same kind of social and economic background. Iago insinuates that while she might have found Othello to be a novelty, in the long run she is more likely to stick with someone who is more like her. Othello, unfortunately, is keenly aware of the differences and his self-confidence is vulnerable; Iago knows it so that's where he figuratively shoves the knife.
Cassio and Desdemona know each other through their connection to Othello. Cassio is Othello's lieutenant, and Desdemona is Othello's wife. Their acquaintance grows as Desdemona advocates for Cassio after he is dismissed from his position, seeking to restore his honor and reputation in Othello's eyes.
If Desdemona asked a favour on Cassio's behalf, it would look to Othello like she was doing it out of an improper love for Cassio. The harder she argues, the more suspicious it seems to Othello.
When Iago tells Othello Cassio slept with her.
The advice that overwhelmed Othello was to kill Desdemona and he will take care of Cassio
Iago sets out to trap Othello by several means. He persuades Desdemona to plead for Cassio and persuades Othello that Desdemona pleading for Cassio proves she is in love with him. He steals the handkerchief, persuades Othello that she has given it away to Cassio, then gives it to Cassio himself. He gets lucky as Cassio gives it to Bianca and she returns it in Othello's sight. He talks to Cassio about Bianca, telling Othello who can see (but not hear) that he is talking about Desdemona. All of this circumstantial evidence bolsters the outright lies that Iago tells about Cassio admitting to having an affair with Desdemona.

Because Othello is unsure of Desdemona's actions. He is afraid of losing Desdemona to Cassio.
Iago tells Cassio that he must persuade Othello to reinstate him. He says "the general's wife is now our general" and so the best way to persuade Othello is to get Desdemona to plead on Cassio's behalf. Since Iago has also told Othello that Desdemona and Cassio are having an affair, the harder Desdemona pleads, the worse it is going to look for both her and Cassio.
While Othello is hiding, Iago and Cassio discuss Desdemona. Iago uses this opportunity to manipulate Cassio into speaking favorably about Desdemona, knowing that Othello is eavesdropping. This conversation plays a crucial role in Iago's scheme to incite jealousy in Othello regarding Desdemona's loyalty.
Othello's mother gave him the handkerchief, and he gave it to Desdemona. When he sees Cassio with it, he assumes that Desdemona had given it to him.
