(1) Which is the ICMP protocol layer?
(2) Ping – which protocol is implemented in ping?
(3) FTP – which protocol is implemented in ftp?
(4) What kind of handshaking is used in TCP/IP?
(5) IP addressing ClassA , ClassB , ClassC
(6) End to end error correction is done by which layer ?
(7) Question on address bus and data bus ALE
(8) 16 bit address bus and 8 bit data bus , how much memory can be interfaced ?
(9) 1 bit opcode , (n-1) operand , find the length of Program Counter
(10) 4 bit ROM
(11) What is the benefit of memory interleaving ?
(12) How many maskable and non-maskable interrupts are there in 8085 (again microprocessor / microcontrollers related question for electronics – ece / computer science – cse / IT branches)

{
char b[7];
char *s;
};
struct b
{
char *t;
struct a y;
