What component of the computer keeps track of the address in memory of the programming instruction being executed?
A stored-program computer at least needs to know which instruction it has to execute next. Other memory addresses of special significance are e.g. the top of one or more stacks, or addresses to be used by instructions.To keep track of such addresses, all CPUs have one or more registers; for instance the address of the next instruction is stored in the instruction pointer, a.k.a. program counter. Which and how many registers of a CPU are designated to keep addresses depends on the CPU type. The Z80 for instance has a program counter, a stack pointer, two index registers and an indirect address register doubling as 16 bit accumulator, while the contemporay 6502 only has a program counter and a stack pointer.
What tiny unit of information storage consisting of an onoff signal?
Bit.
Why is my 64 bit computer running in 32 bit?
64 bit OSes use special set of instructions as well as 64 bit memory space which is in principle is not supported by 32 bit processors.
What is difference between relative file and indexed sequential file?
Relative:- 1. In this mode the content of the program counter is added to the address part of the instruction to obtain the effective addressed. 2. Effective Address = Contents of the program counter + contents of address field. 3. No extra index bit is used. 4. Example:- EA = [ BX ] + [ SI ] + disp. EA = [ BX ] + [ DI ] + disp. Indexed:- 1. In this mode of addressing an attempt is made to avoid the use of two addressed for an operand. 2. Effective Address = Address field + contents of the specified - index registers. 3. In this extra index bit is used. 4. Example:- EA = [ BX ] + [ SI ] EA = [ BX ] + [ DI ]
What are the three mids built in tests?

No of flip flop in 5 bit ripple counter?

How do you draw a solar sytem?
you get a pen or pencil and a bit of paper and start to draw.
What is a 2 bit counter?
a 2 bit counter is a counter which have only 2 bits i.e. the posibble counting states are 00, 01, 10,11,00. It may also be known as MOD 3 counter. It can be realized by using 2 Flip flop.

How do you select a chart or delete?
Carefully click on the chart area. As a chart is made up of different sections, you have to avoid clicking on the actual chart, but a bit outside until the entire chart area is chosen. Then press the delete key to delete it.

Why is it called a pie chart?
Because it looks a bit like a pie, with the sectors as "slices".
