UDP is the FASTER protocol as it doesn't WAIT for ACKNOWLEDGEMENT so it is not at all having reliability as compared to TCP.

UDP is the faster protocol as it doesn't wait for acknowledgement so it is not at all having reliability as compared to TCP.

No. The IP ADDRESS of a system is the logical address where as the address of the MODEM is the MAC(MEDIA Access Control) ADDERESS, it is the physical address provided by the vendor.

No SSL can not SUPPORT in UDP BEACUSE in UDP is a CONNECTIONLESS protocol it is focused on the speed than the security.

As, single character is of 8 bits.So,

{8*100000}/2000 = 400 SEC

As, single character is of 8 bits.So,

{8*100000}/2000 = 400 sec

8/2000 = 0.004 SEC.

8/2000 = 0.004 sec.

100/2000 = 0.05 SEC.

100/2000 = 0.05 sec.

We need 10 bits to show 1024 colors in a BINARY system, THEREFORE 10 bits are REQUIRED for each pixel to be addressed. 

We need 1300*1000*10 bits to SEND a complete content of a screen.

Two types of transmissions

1. Serial
2. parallel

serial means sending one bit at a TIME on a single WIRE USED over LONG distances more EFFICIENT used to send data to external systems

Parallel means sending bits at a time on different wires used over short distances efficient but not serial used to send data in internal transfers

• Named after the Trojan Horse of ancient Greek history, a trojan is a network software application designed to remain hidden on an installed computer. Trojans generally serve maliciious purposes and are therefore a form of malware, like viruses. 
• Trojans sometimes, for example, ACCESS personal information STORED locally on home or business computers, then send these data to a remote party via the Internet. 
• Alternatively, trojans may serve merely as a "backdoor" application, opening network PORTS to allow other network applications access to that computer. Trojans are also capable of launching Denial of Service (DOS) attacks. A COMBINATION of firewalls and antivirus software protect networks against trojans. 
• Trojans are similar to worms. In contrast to worms and viruses, however, trojans do not replicate themselves or seek to infect other systems once installed on a computer.

In IP HEADER PROTOCOL field is available,it tells which protocol it is using as a TRANSPORT layer,if this field is having 6(in decimal)it indicates TCP,17(in decimal)it indicates UDP.

ACTUALLY ip header is not in a udp message.It a COMES atnetwork link layer while udp messege GENERATE at TRANSPORT layer.

To implement the UDP service we must CREAT socket by socket system call which TAKES ARGUMENT as SOCK_DGRAM which is used for to pass the data in the form of datagrams.

The first thing is UDP is connection LESS where as TCP is connection oriented.The broadcasting and multicasting software is available in the UDP only.Why because it is connection less hence we can broadcast the PACKETS very easily,no need to WAIT for connection like in tcp,which takes more DELAY.
