Computer Awareness Questions

a)function declaration

header file contains function declarations,type def, enum, global variable declaration,macros, symbolic literals

c. flag register

The conditional results after execution in an micro processor are stored in flag register which is a part of psw.

b) right to left

It is compiler dependent.  Most of the time all compilers on same platform follows same scheme but it is not defined by ANSI standard. In SPARC processor machines parameters are passed in registers rather then stack.

e) None of the above.

(a) Stack is LIFO
(b) Queue is FIFO

Queue

Terminal emulation is the software which allows personal computer to pretend as a computer terminal.

Tx and Rx should be visible because for proper transmission there should be a connection between the transmitter and receiver,hence Tx and Rx should be visible to each other.

We know that 1 Byte=8Bits,Hence 2^8=256.

A bite can represent one of these 256 distinct values i.e,numbers between 0(min) to 255(max).

Hence the maximum decimal number accommodated in a byte is 255.

The output is 1000/2=500.

We can use command line arguments in C/C++ according to my knowledge.

The sscanf derivative reads input from a character string passed as the first
argument.

The prototypes are as follows: (C or C++)

sscanf (const char *str, const char *format, ...);

PHP

mixed sscanf (const string str, const string format [, mixed args...])

(a). Immediate addressing mode

Concatenate (join) s2 string with s1 string and the result is stored in s2.

IT concatenates the string s1 with s2.

If the entire band of frequency is considered for transmission the sampling rate would be 2*20khz (= = 40khz ) or above in such a case the probable answer would be option "d=64Khz"but for transmission...

Most of the LANs works in Layer 2, so that No need of Network Layer. When routing comes into picture, Network Layer is required.
