The next important effort in the direction of devising an electromechanical computer was made at Harvard University mutually sponsored by IBM and Department of UN Navy, Howard Aiken of Harvard University created a system known as Mark I in 1944. Mark I was a decimal machine means that computations were performed employing decimal digits.
Some of you should have heard a term known as 'bug'. It is mostly used to denote errors in computer programs. This term was invented when one day a program in Mark-I didn't run accurately because of a moth short-circuiting the computer. Since then moth or bug has been linked with problems or errors in computer programming. So process of eliminating error in a program is termed as 'debugging'.
The common shortcomings of these electromechanical and mechanical computers were:
Change was to have a storing and switching mechanism with no moving parts. The electronic switching device 'triode' vacuum tubes were used so first electronic computer was born.
Using the memory map below; design an absolute decoding circuit. The technique is to spot the differences between the start and stop of each device. The Ram chip has the follow

Interval between the time of submission and completion of the job is? Ans. Turnaround time is the interval in between the time of submission and completion of the job.
Design a serial 2’s complementer with a shift register and a flip-flop
Granularity In parallel computing, granularity is a important measure of the ratio of computation to communication. Coarse Granularity: relatively huge amounts of computa
Chaining: In this method, instead of hashing function value as location we use it as an index into an array of pointers. Every pointer access a chain that holds the element having
design modulo 12 up synchronous counter using t flip flop
