Almost every control panel comes with the option of checking your access log details. Access logs make you better understand your website audience by provide you with full details about  your visitors information which includes but is not limited to-  Ip address of your website visitors.
 - Date and time of their visit
 - Duration of their visit
 - Geographical location of the visitors
 - Which pages got mostly seen and how much data is downloaded.  
 
2. Apache : Apache  is a free ware open source software. Apache is mainly used for web  server management.Because of it's open source it is most widely used  software for web servers.Even big companies like Google use it for their  web server.When Apache first came, it was meant to be only for UNIX  servers but as many upgrades came later on, made APACHE compatible with  Windows as well as other operating platforms.APACHE is currently in use  by many web hosting companies to manage their client websites. Since  APACHE is open source,the source code can be edited and the software can  be tailor made and this makes APACHE very secure, reliable and  productive. Also their are frequent updates available on the internet  for APACHE up gradation and this makes APACHE even more secure, reliable  and productive.
3. ASP: Acronym for Active Server  Pages. Active Server pages is nothing more than a server side scripting  language which is Introduced by Microsoft to generate dynamic webpages  on the server itself.
ASP is also denoted as a classic ASP, a script engine which uses VB  scripts and works on server only to produce dynamic webpages.
4. ActiveX:  ActiveX is  introduced by Microsoft in an intent to enhance the reusability standard  in programming.  With ActiveX an organization can produce reusable  software parts which can then be recalled or inherited in other  programmings if needed.
5. Add-on: This is a term which is more often used by web hosting companies. An add-on is  something which comes as an extra product or service to enhance the  usability. Add-on are generally included by webmasters to enhance their  site overall performance and provide their visitors with more  interactivity. Add-on are but not limited to guest posting facility,  maps, Facebook integration, commenting feature, Chat etc.
6. Bandwidth: It is also termed as Data transfer in web hosting industry so don't confuse. Bandwidth is something which concerns both web host as well as their clients. A web host will try to put limit on the bandwidth allotment and a client will always look for the plan which provides more bandwidth in less cost.Bandwidth in simple terms means the amount of data that can the downloaded or uploaded in a month by a website. A data can be a simple text file or an image or a video etc. Let's say if you got a content of 5MB which you upload on your website and a visitor downloads it., so the total bandwidth used is 10MB( 5MB for you to upload on your server and 5MB for a visitor to download the file from your server).Bandwidth is also utilized if someone visits your website. So if your analytic shows that your website has 124 page views and if 10KB is used per page view in loading the page then this means that the total bandwidth used in 124 page views is 1 MB. 
7.Backups: Backups means to keep a record or a duplicate copy of your web documents which could be needed in case of  document losses.Web hosts do maintain backup of a website so that if any accident occurs from their or your side, a backup of all your documents is available. Their are some web hosts which offer a backup service of every 24 hours so that you get maximum maximum backups of  your most recent documents.  8.Blog hosting: This is again  a very important feature that most of the people look for when  selecting their web host. Almost every individual blog and almost every  company and business have a blog to show case their product and  features. A  blog hosting is not something extra special when it comes to hosting.  Unlike the traditional hosting a blog hosting provides easy way to  install blogging platforms like WordPress, Joomla, Drupal etc on the  server with a single click etc.9.Cookie: cookies  are often misunderstood as a virus or a spyware but actually a cookie  is something which a web server sends to a web browser to store and is  used when you visit that web server again. Cookies help websites to  understand about your preferences and your likes, what you might be  looking for etc. Big search engine giants like Google use cookies to  show you better ads. In my opinion cookies are safe and do not contain  viruses etc.10.Corn Jobs: A  corn job is something which is more like a robotic stuff. You only have  to pass command once and it will repeat that task on your server  whenever it is scheduled for. e.g. If you set a backup task to be run  everyday at 6 in the morning then the corn will per it's backup job at  every 6 in the morning according to it's server clock.11. Custom mail box: Whenever you register a domain name you get a custom mail box usually  on your domain name e.g. If Facebook was your domain name then a custom  email address on your name could be like shiv@facebook.com.  12.Custom error pages: A  custom error page helps you create a error message page which you can  then redirect using 401 and if a user misspells a URL then instead of  returning an error message you visitor you can help him get redirected back to your home page or any other page that you may like. These custom error pages also help you maximize your traffic.  13.Control Panel: A  control panel is where you manage all your website features and  services. A control panel is used to login to ftp, create and manage  emails, manage disk space, run corn jobs, check bandwidth usage etc. 14. Data Transfer: As discussed above, data transfer is same as Bandwidth usage. Check Bandwidth to know more in case if you don't.15. DNS:  Acronym  for domain name server. Every domain name is joined with it's server ip  address through DNS. So as you register a domain name it is then mapped  with the server ip address so that whenever a person types in your domain name he/she gets transferred to the right server. 16. Dedicated Server: There are  many kinds of server a web host has to offer which includes shared,  virtual, dedicated and cloud hosting etc. A dedicated server is costly  but it comes with little or no limitation. Your files are not shared and  you have access to a full dedicated server and no one shares it with  you. You can host as many files and sites as you want etc. To know more  on more on Dedicated servers check
