75723. Assertion (A): In C a variable name can have upto 8 characters and special symbols can also be part of variable name.Reason (R): In C a type declaration at the beginning of program indicates the type of variable name used in the program.
75724. A string constant in basic is
75725. Assertion (A): In 8085 when RESET OUT goes low processing begins. Reason (R): CPU remains reset till RESET IN signal goes high.
75726. In microprocessor 8088
75727. In 8085
75728. Assertion (A): Microprocessor 8085 has an 8 bit register called accumulator which stores intermediate answers during a computer operation.Reason (R): Accumulator can send or receive data.
75729. Assertion (A): Interfacing means synchronisation of digital information transmission between input output devices and computer.Reason (R): A computer with higher bit word size executes programs at a faster rate.
75730. IC 74181 is a 4 bit device.

75732. Which of the following buses does not exist in 8085?
75733. The sign of a floating point number depends on
75734. Assertion (A): A higher level language is less efficient that machine language but more efficient than assembly language.Reason (R): It is easier to learn and use higher level language than machine language.
75735. The accumulator drives the ALU.
75736. System bus is the communication channel between microprocessor and peripherals.
75737. Assertion (A): A dynamic RAM chip has much smaller cell than a static RAM chip.Reason (R): In dynamic RAM one bit of information is stored as the charge on a capacitor.
75738. Which of the following produces very wide drifts in clock frequency?

75741. The register set and instruction set of 8088 is similar to that of
75742. Assertion (A): In direct addressing the address of operand is specified in the instruction.Reason (R): Direct addressing is also called absolute addressing.
75743. Assertion (A): In Fortran 77 the statement IMPLICIT INTEGER (A - E) identifies all variable name which begin with A, B, C, D, or E as being of integer type.Reason (R): IMPICIT statement in Fortran 77 is an improvement over earlier versions of Fortran.
