lovanofm — 2014-03-21 09:43:54 UTC

The domain name that is used in URL's are used to identify a website because it makes the website unique from others.

Why are domain names preferred over IP addresses?

lovanofm — 2014-03-21 09:45:10 UTC

A domain name is a name which can recognise one or more IP address. Whereas an IP address is only used for one computer/device.

Using an example - explain where the domain name appears in a website address.

an example of where the domain name appears in a website address, is as follows.

WWW.Google.com, within this address the domain name is Google. As well as the COM being the general top level domain name (gTLD). the use off domain names makes it so that the web can direct the user to the correct site.

when choosing a domain name the factors to be considered are

What else can be considered if the user mistypes the website address?

lovanofm — 2014-03-21 09:47:05 UTC

The Sophos Study reveals that 80% of mistyped web addresses (URLs) lead to 'typosquatting' sites.

Typosquatters register mis-spellings of popular websites in the hope that they will be able to make money out of traffic from unintentional typing mistakes made by internet surfers.

What are some of the newest additions to domain names and how are they created

2014-03-21 09:50:37 UTC

when considering making a domain name for your computer these must be taken into account

Host (A) -- This is the basic mapping of IP address to host name, the essential component for any domain name.
Canonical Name (CNAME) -- This is an alias for the domain. Anyone accessing that alias will be automatically directed to the server indicated in the A record.
Mail Exchanger (MX) -- This maps e-mail traffic to a specific server. It could indicate another host name or an IP address.
Name Server (NS) -- This contains the name server information for the zone. If you configure this, your server will let other DNS servers know that yours is the ultimate authority (SOA) for your domain.
Start of Authority (SOA) -- This is one larger record at the beginning of every zone file with the primary name server for the zone and some other information. however if your company is in control of your DNS server, you won't need to manage this.

Step by Step on Making a New DNS

2014-03-21 09:53:36 UTC

Use the Whois database to find a unique domain name that isn't yet registered. There are several sites that offer free Whois database searches, such as Network solutions If the search comes up empty, you know the domain name is available.
Register the domain name with a registrar. There are a lot of registrars to choose from, and some offer special prices for registering the COM, NET, and ORG versions of a domain at the same time, for registering for two or more years, or for hosting the domain with the same company.
If you're hosting the domain at a different company than your registrar, configure the registrar to point your domain name to the correct host name or IP addressfor your hosting company (see information below about A records).

Explain the purpose of a mail server

lovanofm — 2014-03-21 10:25:58 UTC

This collects and distributes emails to users. The mail server works in conjunction with other programs to make up what is sometimes referred to as a messaging system. A messaging system includes all the applications necessary to keep e-mail moving as it should. When you send an e-mail message, your e-mail program, such as Outlook, forwards the message to your mail server, which in turn forwards it either to another mail server or to a holding area on the same server called a message store to be forwarded later.

Purpose of a web server

2014-03-21 10:26:32 UTC

The purpose of a web server is to host a website for users to connect to.

Proxy Servers

The purpose of a web server is to host a website for users to connect to.

They generally have to have fast upload speeds, this is because they need to distribute a lot of information to different users.

Proxy servers are servers that act as an intermediary for requests from clients seeking resources from other servers.

Proxy servers can be used in a number of different places, for example content-filtering proxy servers can be used in many work places such as schools and colleges ( We don't have it at college, LOL JK )

What is the POP protocol

lovanofm — 2014-03-21 10:29:06 UTC

POP is short for Post Office Protocol, a protocol used to retrieve e-mails l from a mail server. Most e-mail applications (sometimes called an e-mail client) use the POP protocol, although some can use the newer IMAP.

How is a web server different from a normal pc?

2014-03-21 10:30:54 UTC

A web server is a computer dedicated to being able to run all of the time. Therefore it can not have any overheating problems. Also web servers might sacrifice graphics processing and go for a much stronger CPU and a lot more ram. This is because it has to be able to send a lot of data really fast.

You would also need specific Software to host servers. For example if you want to run a minercraft server, you have to use the minecraft server software.

What is IMAP and SMTP ?

lovanofm — 2014-03-21 10:31:33 UTC

IMAP: As its name implies, IMAP allows you to access your email messages wherever you are; much of the time, it is accessed via the Internet. Basically, email messages are stored on servers. Whenever you check your inbox, your email client contacts the server to connect you with your messages. When you read an email message using IMAP, you aren't actually downloading or storing it on your computer; instead, you are reading it off of the server. As a result, it's possible to check your email from several different devices without missing a thing.

SMTP:

Short for Simple Mail TransferProtocol, a protocol for sending e-mail messages between servers. Most e-mail systems that send mail over the Internet use SMTP to send messages from one server to another; the messages can then be retrieved with an e-mail client using either POPor IMAP.
