Javascript commands are executed on a server computer. When you write a Javascript program, you write it on your own computer. But when you run the program, the Javascript code is sent to a server, where it is executed.
This has some important implications. For example, it means that you can’t use Javascript to create programs that run on your own computer. It also means that you can’t use Javascript to create programs that interact with the user’s computer.
Instead, you can use Javascript to create programs that run on a server, and that interact with users through a web browser.

What is responsible for the Internet’s domain name system?
The Domain Name System (DNS) is responsible for translating human-readable domain names into machine-readable IP addresses. Every time you visit a website, your computer needs to lookup the website’s IP address in order to connect to it. The DNS is what makes this process possible.
The DNS is a distributed system that consists of a set of servers around the world known as DNS servers. When you type a domain name into your web browser, your computer will query a DNS server to get the IP address for that domain. The DNS server will then return the IP address to your computer.
The DNS is a critical part of the Internet infrastructure and it plays a role in ensuring that users can access websites quickly and reliably. The DNS is also responsible for preventing cyber attacks by helping to identify malicious websites.
Which of the following is an example of an instant message service?
Instant messaging (IM) is a type of online chat that allows two or more people to communicate in real time. It’s similar to texting, but because it’s done through a chat client, users can see each other and type messages faster than they could with a phone.
IMs can be used for a variety of purposes, from talking to friends to business collaboration. They’re also popular for communicating with people in different time zones, since you can message them at any time and they’ll see your message when they next check their chat client.
There are a number of different instant messaging services available, but some of the most popular are WhatsApp, Facebook Messenger, and Skype.
Is the process of encoding data so that only the person with the key can decode and read the message?
When it comes to encrypting data, there are a few different ways to do it. One common way is to use a key to encode the data so that only the person with the key can decode and read the message. This is known as a symmetric key algorithm.
There are a few different symmetric key algorithms, but the most common is the Advanced Encryption Standard, or AES. AES is a 128-bit algorithm, which means that it can encode 128 bits of data at a time. It is considered to be very secure, and is used by the US government and many other organizations to encrypt their data.
To encrypt data with AES, you first need to create a key. This key can be any length, but most people use a key that is 128, 192, or 256 bits long. Once you have your key, you can use it to encode your data.
To do this, you first need to convert your data into binary form. Binary is a system of encoding data using only 0s and 1s. Once your data is in binary form, you can use your key to encrypt it.
To encrypt your data, you simply need to XOR it with the key. XOR is a mathematical function that takes two binary values and returns a third. The XOR of two binary values is 1 if and only if the values are different. If the values are the same, the XOR is 0.
For example, let’s say you want to encrypt the value 12. You would convert it to binary, which would be 1100. Then you would XOR it with the key, which would be 1010. The XOR of these two values is 1000, which is the encrypted value.
To decrypt the data, you simply need to XOR it with the key again. This will return the original value, 12.
As you can see, encrypting data with a key is a relatively simple process. It is a very secure way to protect your data, and is used by many organizations around the world.
Which of the following organization is responsible for the Internet’s domain name system and the allocation of IP addresses?
The Internet Corporation for Assigned Names and Numbers (ICANN) is a nonprofit organization that is responsible for the domain name system (DNS) and the allocation of IP addresses. The DNS is the system that allows us to access websites by typing in their domain names, rather than their IP addresses. ICANN also oversees the management of the top-level domains (TLDs) that are used on the Internet.
IP addresses are the unique identifiers that are assigned to every device that connects to the Internet. ICANN is responsible for allocating IP addresses to entities around the world. This is a complex process, and it is becoming increasingly difficult to find available IP addresses that are not already in use.
ICANN was founded in 1998, and it is headquartered in Los Angeles, California. The organization is governed by a board of directors, which is appointed by the president of the United States. ICANN is a member of the Internet Architecture Board (IAB) and the Number Resource Organization (NRO).
Where is the DNS server located?
Domain Name System (DNS) servers play an important role in internet security and performance. They store and manage the domain name system database and translate domain names into numerical IP addresses. DNS servers are located all over the world, but their precise location can vary depending on the service provider.
DNS servers are managed by various organizations, such as internet service providers (ISPs), governments, and large companies. The servers are typically hosted in data centers, which are large, secure, and well-equipped facilities. These centers are used to house a variety of internet-related equipment, including servers, routers, and switches.
ISPs are responsible for managing the DNS servers that are used to resolve domain names for their customers. They typically have a large number of DNS servers located in their data centers. Governments and large companies also operate their own DNS servers.
The location of a DNS server can impact its performance. For example, if a DNS server is located in a remote area, it may take longer for requests to be processed. This can cause webpages to load more slowly and affect overall internet performance.
The best way to ensure optimal DNS performance is to use a DNS server that is located close to your location. This will minimize the amount of time it takes for requests to be processed. You can use a tool like WhatIsMyIP to find the IP address of the DNS server nearest to you.
If you are having trouble connecting to a website or experiencing slow performance, you can try using a different DNS server. There are a number of free and public DNS servers available, such as Google Public DNS and OpenDNS. These servers can be used to improve internet performance and security.
What is DNS server in computer network?
Domain Name System (DNS) servers are an important part of computer networks. They act as a directory of domain names and their corresponding IP addresses. This allows devices on a network to connect to other devices using domain names instead of IP addresses.
DNS servers are typically implemented as a part of the network infrastructure, and are usually provided by the network operator. They can be implemented on-premises or in the cloud.
DNS servers are used to resolve domain names into IP addresses for devices on a network. When a device attempts to connect to a domain name, the DNS server will look up the IP address for that domain and return it to the device. This allows devices to connect to other devices on the network using domain names instead of IP addresses.
DNS servers can also be used to store records for domain names. This can be used to resolve domain names into IP addresses even if the DNS server is not currently connected to the internet.
DNS servers are an important part of computer networks, and are used to resolve domain names into IP addresses for devices on a network.
What apps use chat data?
What apps use chat data?
This is a question that is on a lot of people’s minds, especially in the wake of the Facebook data scandal.
So far, it has been revealed that the Facebook app, as well as the WhatsApp and Instagram apps, all collect data from users’ chats.
This data is then used to target ads and to create user profiles.
It is not yet known exactly what other apps are collecting this data, but it is likely that many more are doing so.
This is a worrying trend, as it means that our chat data is being collected and used without our consent or knowledge.
This data is incredibly personal, and it should be up to us whether we want to share it or not.
Unfortunately, it seems that many companies are not respecting our right to privacy.
We need to be more careful about which apps we use, and we need to be more vocal about our concerns about data privacy.
We also need to push for tighter regulation of how data is collected and used.
Only then will we be able to protect our privacy and keep our chat data safe.
