First generation of computer | Advantages and Disadvantages of first-generation computers

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.

The general technical features of the first-generation computer are -:

(i)Use of vacuum tubes: The vacuum tubes were used in the circuits of these computers.

(ii) Bulky size-: They were too bulky in size, requiring large rooms for installation.

(iii) Use of punch card -: The input and output operations were done using punched card technology.

(iv) Use of magnetic memory-: For external storage magnetic taps were used. The magnetic drum was used as internal memory.

(v)  Limited application -: Since these computers were difficult to program and use they have limited commercial use.

(vi) speed-: The processing speed was very low. These computers can execute a hundred of instruction per second.

(vii) Power consumption-: These computers consumed high power and generate a great amount of heat.

(viii) Programming in machine and assembly language-: These computers had very limited programming capability. They use machine and assembly language for programming.

(ix) Reliability-: Due to the frequent failure of circuits these computers were not very reliable.

 (x) Cost -: The cost of these computers were very high.

Examples-: The computer belongs to the first generation are EDVAC, UNIVAC, IBM700, IBM7001, IBM709, MARK I, MARK II.

Gray Code and BCD Code(Binary Coded Decimal)

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

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.
