Solution basically, is a cabinet (.cab) file with extension .wsp which contains various components needed to be deployed(features, webparts, custom forms etc) along with files that describe some important metadata about those Components. Once a Solution is installed on a server in the farm, you can deploy it to any webapplication from your Solution Management.

Dedicated language translation maintenance
Dedicated galleries for web parts, master pages, content types, site columns, site templates, and list templates
Dedicated shared libraries, such as site collection images and site collection styles
Dedicated real estate (Self Containment)

For the IT Administrators:
Site quota templates
Distributed administration
Site locking
Database maintenance options
Backup / Restore abilities

Q. When would you use a Different Site Collection for you new site?.
Ans. We would prefer to make our new site in a seprate site collection for the following are the reasons:
1. Site quotas is one of the reasons. The issue is the recycle bin is based on site collections and the quota for a site collection. If everyone shares a site collection, then they share the recycle bins storage size.

2. Delegated Security and distributed administration is the next big thing. For eg, you have a IT department that doesn’t know who should be able to see what content, besides how it should be organized. This is the job of the content owners and users. SharePoint site collections offers IT the ability to create a site collection for a project, team, department, document, or whatever the needs are, then assign an owner and hand it off to them.

3. In addition to these two if you need to separate the content between databases because of space issue.

Q. What is a Field Control?
Ans. Field controls are server controls that provide the basic field functionality of SharePoint. For example a Inputbox (single line text) to enter the title of the item. You can create your own FieldControl by inheriting classes from BaseFieldControl namespace.

protected override void LoadViewState(object savedState) //Only at Postback
protected override void OnPreRender(EventArgs e)
protected override void Render(System.Web.UI.HtmlTextWriter writer)
protected override void OnUnload(EventArgs e)
public override void Dispose()

Q. While creating a Web part, which is the ideal location to Initialize my new controls?
Ans. CreateChildControls is the method where we initialize all the child controls.

Q. Do we always need to override Is Render() method.
Ans. We override render only in case if we need to define the rendering of our controls in the webpart.

Q. What is the WebPartManager sealed class?
Ans. The WebPartManager sealed class is responsible for managing everything occurring on a WebPart page, such as the WebParts (controls), events, and misc. functionality that will occur in WebPartZones. Each Page will have only one WebPartManager reference on the page.

Q. What are WebPart Properties?
Ans. WebPart Properties are properties defined from the right toolpane of the webpart. These are settings or values set by the end user and are used within your webpart. For e.g. WebPart title, Description etc. Some of the attributes which you can define for your custom property are WebDescription, WebDisplayName, Category, Personalizable, and WebBrowsable.

Q. How does Windows SharePoint Services help render the Webapplictaion in ShrePoint?
Ans. When a new web applictaion is created via Central Admin, Windows SharePoint Services creates a new Web application in IIS. Then the WSS, loads the custom HTTP application and replaces all installed HTTP handlers and modules with Windows SharePoint Services–specific ones. These handlers and modules essentially tell IIS to route all file requests through the ASP.NET 2.0 pipeline. This is because most files in a SharePoint site are stored in a Microsoft SQL Server database.

Q. What files gets created on a file system, when a Site collection is created ?
Ans. Windows SharePoint Services does not create any files or folders on the file system when the site collection or sites are created; everything is created in the content database. The Pages for the site collection are created as instances in the content database. These instances refer to the actual file on the file system.

Q.How Does SharePoint work?
Ans. The browser sends a DAV packet to IIS asking to perform a document check in. PKMDASL.DLL, an ISAPI DLL, parses the packet and sees that it has the proprietary INVOKE command. Because of the existence of this command, the packet is passed off to msdmserv.exe, who in turn processes the packet and uses EXOLEDB to access the WSS, perform the operation and send the results back to the user in the form of XML.

Q. What is Authentication and Authorization.
Ans. An authentication system is how you identify yourself to the computer. The goal behind an authentication system is to verify that the user is actually who they say they are.
Once the system knows who the user is through authentication, authorization is how the system decides what the user can do.

Q. What are Security methods(Authentication methods) available in sharepoint
Ans. “Out of the box”, SharePoint 2007 supports nine authentication methods. But NTLM (Windows authentication) and Kerberos (Windows “standard” authentication) are offered during installation.
