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.
What are modes of operation of centralized SPC? In about all the present day electronic switching systems utilizing centralized control, only a two-processor configuration is
Function name or connective symbol: Whether if we write op(x) to signify the symbol of the compound operator then predicate name and function name or connective symbol are the

EPROM contents can be erased by exposing it to ? Ans. By exposing EPROM contents to Ultraviolet rays, it can be erased. The Ultraviolet (UV) light passes throughout a window i
Why is fragmentation needed on Internet not on a typical WAN? TCP/IP protocol utilizes the name IP datagram to demote to an Internet packet. The amount of data carried into a d
Define addressing modes. The dissimilar ways in which the location of an operand is specified in an instruction are referred to as addressing modes.
A very useful application of assembly is to generate delay loops. These loops are used for waiting for some time before execution of subsequent instruction. However how to find
