Disk Oprating System (DOS) डॉस DOS ( डिस्क ऑपरेटिंग सिस्टम) एक पुराना संगणक संचालन प्रणाली है जो कि विण्डोज़ संचालन प्रणाली के आने से पहले प्रचलन में था। बाद में इसको माइक्रोसॉफ्ट ने खरीद लिया तथा इसका नामकरण ऍमऍस-डॉस किया।   DOS ij tkus dk rjhdk & Run ij command fy[kdj Enter nckrs gSaA vFkok Start        All Program          Accessories         Command Prompt MkWl vkWijsfVax flLVe ,d flLVe lkW¶Vos;j gksrk gSA tks dEI;wVj ds gkMZos;j vkSj lkW¶Vos;j ds ohp lEcU/k LFkkfir dj gkMZos;j vkSj lkW¶Vos;j dks fu;af=r djrk gSA MkWl dk eq[; dk;Z Qkbyksa dk ÁcU/ku ,oa Á;ksxdrkZ }kjk fn;s x;s vkns”kksa dk ikyu djuk gSA ikFkZ ls rkRi;Z %&fdlh Hkh Qkby dks ÁkIr djus ds fy;s Mªkbo dh ewy Mk;jsDVªh ,oa mldh mi&Mk;jsDVªh esa tkus dh vko”;drk gksrh gS ftlesa Qkby lqjf{kr gSA bl Ádkj Qkby dk jkLrk dEI;wVj dks crkuk Qkby dk ikFk Ánf”kZr djuk dgk tkrk gSA ...

K-Map (Karnaugh Map) In many digital circuits and practical problems we need to find expression with minimum variables. We can minimize Boolean expressions of 3, 4 variables very easily using K-map without using any Boolean algebra theorems. K-map can take two forms Sum of Product (SOP) and Product of Sum (POS) according to the need of problem. K-map is table like representation but it gives more information than TRUTH TABLE. We fill grid of K-map with 0’s and 1’s then solve it by making groups. Steps to solve expression using K-map- Select K-map according to the number of variables. Identify minterms or maxterms as given in problem. For SOP put 1’s in blocks of K-map respective to the minterms (0’s elsewhere). For POS put 0’s in blocks of K-map respective to the maxterms(1’s elsewhere). Make rectangular groups containing total terms in power of two like 2,4,8 ..(except 1) and try to cover as many elements as you can in one group. From the groups made in step 5 find the p...
