• Network Address Translation (NAT) is used to keep track of the packets with respect to their IP address.
• Since, it is used as a security technique, I request my friend to use NAT between the router and system or computer to set a cable internet connection.
Therefore, the appropriate word to fill in the blank is Address.
Evolution of internet
Evolution of computers is comprised of mainly 3 events given below:
1. Creation of ARPANet
2. Development of TCP
3. E-mail feature
The explanation of all 3 events is given below:
1. Creation of ARPANet: After the launch of first artificial satellite "Sputnik" in 1957, the internet was started. In 1969 ARPANet was created by ARPA which is advanced research project agency. The main purpose of ARPA is to create a system of internetworks with which many separate networks can be joined to form a large network. Internet is a collection of Internet service provider which handles their own network and client and also connects with other network.
2. Development of TCP: In 1982, TCP (Transmission control protocol) was developed. A protocol is a set of rules which is used to transfer data between networks. Two or more networks when connected to each other forms internet. Internet was designed for communication between networks.
E-mail feature: When internet was created, it was not so friendly and hence it was used by engineers and scientists. Person who wants to use internet has to learn a lot of complex things about internet. Email was added to internet system in 1972. "@" symbol was used in emails for connecting username with the address. A lot of protocols like TELNET, FTP, PPP, TCP, IP etc were created to govern the connection.
Now, internet is too huge. A lot of users are accessing the internet as per the need. A large amount of information is stored on the internet about almost each and every topic. And internet is very necessary for students, teachers and everyone who want to learn anything can use internet.
Difference between Ping and Traceroute
Ping and Traceroute are the utilities used by computers. Ping utility is used determine the accessibility of a specific IP address and Traceroute utility is used for tracing the data packet from user computer to internet host.
Some differences between Ping and Traceroute are given below:
Example: If user wants to use both utilities for IP (google.com), then in the command prompt, the commands for Ping and Tracert should be entered.
For Ping: The command that user enters for Ping is 'Ping google.com' the output that will be obtained is shown below:
For Traceroute: The command that user enters for Ping is 'Tracert google.com' the output that will be obtained is shown below:
