2 câu trả lời

Client-server phân tán các tài nguyên và dịch vụ trên toàn mạng.
- Server chuyên trách chạy những phần mềm Server đặc biệt và cung cấp các dịch vụ cho các máy khách.
- Các máy khách là những trạm làm việc hay máy trạm, nơi người dùng chạy các ứng dụng để xử lý dữ liệu.
- Các Server là những kho chứa thông tin và cung cấp các dịch vụ cho các máy trạm.
- Máy khách và máy trạm được nối kết thông qua nhiều thiết bị và cáp nối.
- Server luôn là máy tính phức tạp và mạnh mẽ hơn, chạy những phần mềm cũng phức tạp và mạnh mẽ hơn các máy

Trong một mỗi nút mạng đều có vai trò ngang nhau. Trong mô hình hày thì không có máy chủ ở trung ương chuyên cung cấp các dịch vụ xử lý cho mọi nút mạng hay máy khách.

·Mọi nút mạng có thể thực hiện chức năng như một máy khách mà cũng có thể như một Server trong mạng, có nghĩa là việc liên lạc trực tiếp giữa các máy khách của mạng diễn ra mà không cần có một Server chuyên trách nào cả.

·Mỗi nút mạng đều có thiết bị lưu trữ của riêng nó và đều có thể truy cập đến các nút mạng khác.

Read the passage and choose the best answer (A, B, or C) to the following questions (5 pts) What do you often do after school? In my school, there are a lot of clubs which students can take part in after school hours. The club that has the biggest number of members is the swimming club called “Blue Dolphins”. I myself love swimming so I am a member of this club. I go to the swimming pool twice a day and swim for about an hour. I‟m really interested in swimming breaststroke because it helps me move as fast as I can. I‟m also fond of backstroke. I swim backstroke when I want to relax, breathe and let my body float freely. It‟s very relaxing. The second club I would like to mention is the charity club. Its name is “Golden Heart”. Members of the club often do community service. This month, they are conducting a clean-up campaign to protect the environment around the school. They collect trash, clean the toilet area, and grow plants. I am not a Golden Heart‟s member, but I participate in their activities whenever I can. If you can sing, dance or play musical instruments, the musical club “Heartstrings” is definitely for you. The president of the club is Mike, my best friend. He is not only good-looking but also sings beautifully and plays the guitar very well. In conclusion, we should do as many activities as possible in our free time to have good health and a fresh mind to prepare for lessons in class. Spending all our time studying is not a good idea. 6.
