sains komputer

salam.

aku seorang pelajar matrikulasi perak,modul 3 (biologi, matematik, kimia, dan sains komputer)

setelah beberapa minggu belajar sains komputer mendalami serba sedikit mengenai sains komputer.contohnya,aku dapat mengetahui makna sebenar komputer,internet dan pelbagai lagi.Ilmu-ilmu tersebut juga akan digunakan dalam kelas praktikal.Di situ, saya dapat menilai diri saya sekiranya saya faham ataupun tidak. Selain itu, di kelas tutorial saya dapat berbincang serba sedikit masalah yang merunsingkan, contohnya soalan tutorial yang tidak dapat di jawab. Seterusnya, saya juga dapat menambah pengetahuan mengenai sejarah internet,kebaikan menggunakan internet, dan sebagainya. saya juga dapat mengetahui mengenai komponen-komponen komputer. Setelah beberapa minggu belajar sains komputer, minat saya terhadapnya semakin bertambah.
Setiap kuiz,praktikal dan walaupun di dalam dewan kuliah saya menumpukan perhatian sepenuhnya. hal ini demikian kerana saya telah kenal dengan sains komputer dan ia telah menjadi salah satu subjek yang saya gemari.Bak kata pepatah,"tak kenal maka tak cinta"
