Bồ câu đưa thư nhanh hơn Internet
ột công ty công nghệ thông tin ở Nam Phi vừa chứng minh rằng, dữ liệu được chuyển phát bằng chim bồ câu còn nhanh hơn sử dụng dịch vụ Internet hàng đầu đất nước.Tốc độ và sự kết nối Internet ở quốc gia rộng nhất châu Phi này rất nghèo nàn vì thiếu đường truyền. Giá thành sử dụng Internet cũng rất cao. Một cuộc nghiên cứu gần đây đưa ra kết quả bất ngờ, việc chuyển dữ liệu qua mạng chậm hơn nhiều so với phương thức chuyển phát cổ xưa là dùng chim bồ câu đưa thư.
