Third generation of computer(1965-1974)-:Third generation of computers witnessed major advantages and changes I  hardware and software capacities. The major technological features of computers of this generation are-:

(i) Use of integrated circuits-: Transistors were replaced by integrated circuits. IC’s decreased the size, cost and power consumption to a great extent.

(ii) Input/ Output media-: For input and output operation monitors and keyboards were introduced.

(iii) Use of magnetic disk-: For secondary storage magnetic disk was used which was larger in capacity and faster. For internal memory, a magnetic core was used.

(iv) Use of operating system-: Sophisticated operating system, capable of handling several jobs concurrently were used.

(v) Evolution of easy high-level language-: New high-level language like BASIC, COBOL, PASCAL were developed that allowed programs written for one computer to be easily ported to and executed on another computer.

(vi) Speed-: There was great importance in the processing speed of these computers. There can execute on another computer.

(vii) Cost-: Cost was lower than the second generation.

(viii) Reliability-: These computers were more reliable and less prone to hardware failure than second-generation computers. The maintenance cost was also lower.

(ix) Rise of mini computers-: the minicomputer of third-generation made computers affordable even by smaller companies.

Example-: Major computers of these generations include, IBM307 series, PDP II, CDC700 series, CYBER-175, STAR-100.

Hello friends, today we learn about the First generation of computers, features of first-generation computers ,and  advantages and disadvantages of first-generation computers in it, so let's start. INTRODUCTION - :       The First-generation of computer-: The period of the first generation was from 1940 to 1956. The first-generation computers relied upon the machine language, to owest-level programming language understood by computers, to perform operations, and they could only solve one problem at a time. The first generation computer uses a vacuum tube as the basic component because the vacuum tube is the only electronic component available on those days. The vacuum tube is used for circuitry and magnetic drums are used for memory.  First generation of computer | Advantages and Disadvantages of first-generation computers   The general technical features of the first-generation computer are -: (i)Use of vacuum tubes: The vacuum tubes were

Hello friends, today we learn about gray code and bcd code in it, so let's start Gray Code and BCD Code(Binary Coded Decimal) Gray code-: Digital system process data into discrete form. Many system supplies continuous or analog data nut it should be converted before using it in the digital system. Sometimes Gray code is used for digital system. Gray code belong to the categories of minimum changes code, in which only one bit in the code changes when moving from one code to the next. Gray code is non weighted code it means it does not contain any weight according to its position. The gray code is a reflective digital code which has the special property that any two subsequent numbers code differ by only one bit. Decimal number Binary number Gray code 0 0000 0000 1 0001 0001 2 0010 0011 3 0011 0010 4 0100 0110 5 0101 0111 6 0110 0101 7 0111 0110 8 1000 1100

ASCII CODE AND EBCDIC CODE

Image
Hello friends, today we learn about gray code and bcd code in it, so let's start ASCII CODE AND EBCDIC CODE       ASCII CODE-:   ASCII stands for “ American standard code for information interchanges “ , It has become a world standard alphanumeric code for micro-computer. It is a 7-bit code and it can represent maximum 2 7 =128 different characters. These character represent 26 uppercase letter (A-Z), 26 lowercase letter (a-z), 10 digit(0-9), 33 special symbol character and 33 control characters. The 7 bit of this code are divided into two parts. First 3 bit of left are called zone bits and next four bits of right side are called numeric bits. ASCII CODE AND EBCDIC CODE  An 8 bits version of ASCII code is also available , which is know as USACC-II or ASCII-8. They can represent maximum of 256 characters.
