# Question: Can You Know In Advance The Path A Message Will Take Between You And Another Computer On The Internet?

Can you know in advance the path a message will take between you and another computer on the Internet?

No, because depending on how much traffic there is between other routers the message will take the fastest route possible to the other computer which could change day to day or hour to hour based on the traffic.

## Can you know in advance the path a message will take on the Internet?

Since the path a message will take is always the fastest route, it will always go on the same route in a perfect world. However, internet traffic can make that route slower, and the message is sent along a different route, which is faster than the clogged route. Therefore, we do not know the path a message will take.

## Why do computers need to periodically check the DNS for websites that you have already visited?

Computers need to periodically check the DNS for websites you have already visited because the IP address associated with a given URL or domain is not static rather dynamic-changes with time, and it can change over course of time.

## How do these obstacles mirror actual problems encountered on the Internet?

How do these obstacles mirror actual problems encountered on the Internet? Parts of packets may not arrive (dropped). They may arrive at different times or out of order. In order to constrain the extent of these errors, larger messages are divided into many packets which are individually routed to their recipient.

## Why do we need to know the IP addresses for our favorite sites?

We don’t need to know the IP addresses for our favorite sites because the DNS stores them all for us in a directory like database. It would be too difficult for us to remember each IP address for each individual website.

## Can you know in advance the path a message will take between you and another computer on the Internet Justify your answer quizlet?

Can you know in advance the path a message will take between you and another computer on the Internet? Justify your answer. No you cannot know because there are multiple possible paths determined by the routing algorithm. Small chunks of information that have been carefully formed from larger chunks of information.

## Do your messages always take the same path?

No, messages are always taking different paths so you can’t tell. An Internet service provider (ISP) just purchased all the routers in your area.

## Why don’t we all maintain our own DNS?

Why do we need a Domain Name System? Domain Name System allows users to have the same url or consistent domain name while IP addresses change frequently. We need DNS because without it users would need to keep on checking the IP addresses of others and of themselves to send messages or view sites.

## Why do we need a DNS?

DNS (Domain Name Server) is mainly used to convert human meaningful name (domain name) to computer meaningful name (IP address) in Internet. It allows you to use internet more easily by allowing you to specify a meaningful name on your web browser instead of using IP address.

## Why do computers need to check the DNS?

The Domain Name Servers (DNS) maintain a list for all human readable web-sites (example: www.brainly.com) and their IP addresses. Computers need to periodically check the DNS for websites you have already visited. The reason is because the IP address associated with a given URL is not static, and it can change.

## Why did we decide to send a message as a sequence of states?

Recall when you built your binary message sending device. Why did we decide to send a message as a sequence of states (A and B) rather than modifying our devices to represent more states (State C, State D, State E, )? to represent more states because we wanted to take a complex question and simplify it.

## Does 01000001 always represent 65?

The base 10 number system uses 10 numbers to get all the numbers possible. It is similar with the binary number system because it also uses (exponent) numbers to get a specific number. “The binary pattern 01000001 represents the number 65.”

## What is an Internet Protocol IP address How is it organized hierarchically?

-It is organized hierarchically by each number is represented by bits. IP addresses are 32 bits with 8 bits per part of the address. The system of hierarchy works like this first numbers are usually the country/network, 2nd numbers are region/network, then its subnetwork and finally its the device.
