Breakdown of maikurochippu o kakuninsuru.

Questions & Answers about maikurochippu o kakuninsuru.
を marks the direct object of the verb. In other words, it shows what is being checked.
So in this sentence:
- マイクロチップ = microchip
- を = object marker
- 確認する = to check / to confirm
That makes マイクロチップを確認する literally to check the microchip.
Katakana is often used for loanwords, especially words borrowed from English or other non-Japanese languages.
マイクロチップ is the Japanese borrowing of microchip, so it is written in katakana.
This is very common in Japanese:
- コンピューター = computer
- テスト = test
- スマートフォン = smartphone
So seeing katakana here is completely normal.
