Summary of the text
It’s known to us all that the computers is one of the most important inventions in the 20th century. Though it’s widely used in our daily life, it began only as a _c_a_lc_u_la_t_in_g_ machine in 1642. In 1822, the _a_n_a_ly_t_ic_a_l_machine was made by Charles Babbage. At that time, after the computer was _p_r_o_gr_a_m__m_e_d by an operator who used cards with holes, it could “think” logically and produce an answer _q_u_ic_k_e_r_ than any person. With the time going by, the computer has been made _s_m_a_l_le_r__. Later, computers were __co_n_n_e_c_te_d__ with each other. The information could be _s_h_a_re_d__.
