theories, with video and illustrations so you can learn how everything works. Lava Tubes on Earth Could Prepare Us for Life on the Moon and Mars. SHORT ANSWER: Your first example, how it works, is a free relative clause which cannot be used as a question. Your second, How does it. The second sentence does not form a complete question. The second sentence is spoken when you directly tell that how that device works.
Does Work? How It
It seems that in a prototypical interrogative main clause, e. Oct 15 '14 at In the example "Tom knows what Sue ate" , let's assume that Sue had eaten a ham sandwich, and so, that means that Tom knows the answer to the question 'What did Sue eat?
Here's an example that helps show that a fused-relative is a different beast from that of a subordinate interrogative clause. The fused relative interpretation is 'That which she wrote is unclear' -- a letter or report, perhaps. Oct 17 '14 at 5: Many expressions when taken in isolation could have a shape that could be of different categories. Consider the expression "the bagels you can have", which could be a NP in "Those are the bagels you can have" , or it could be a clause with its object preposed as in A: But the bagels you can have.
It's the matrix clause or the context that is needed to know how to interpret an expression. Often a similar situation arises with subordinate interrogative clauses and fused-relatives. Oct 17 '14 at And what's in the box may represent either an independent interrogative clause or a dependent free relative. But there are both syntactic and phonological reasons for distinguishing those two categories; I see none for distinguishing free relatives from 'embedded questions'.
Do you categorize the school as two different sorts of NP in the two interpretations of "I ran for the school"? Rob knows how it works. But then again, it may be a part of an interrogative sentence, as in: Will you tell me how it works?
I'll correct Maulik's second answer: So now you know how it works, don't you? You see that he sets the expressions in context, which is always very important.
If you're using a sentence fragment rather than a sentence proper in your first example say as a section heading , you'd drop the question mark and probably the period: Edwin Ashworth Edwin Ashworth 4 8.
Azure RMS simply makes the data in a document unreadable to anyone other than authorized users and services:. The data is encrypted at the application level and includes a policy that defines the authorized use for that document. When a protected document is used by a legitimate user or it is processed by an authorized service, the data in the document is decrypted and the rights that are defined in the policy are enforced.
At a high level, you can see how this process works in the following picture. A document containing the secret formula is protected, and then successfully opened by an authorized user or service. The document is protected by a content key the green key in this picture.
It is unique for each document and is placed in the file header where it is protected by your Azure Information Protection tenant root key the red key in this picture. Your tenant key can be generated and managed by Microsoft, or you can generate and manage your own tenant key. First use, content protection, content consumption section in this article. For technical details about the algorithms and key lengths that Azure RMS uses, see the next section.
Even if you don't need to know in detail how this technology works, you might be asked about the cryptographic controls that it uses. For example, to confirm that the security protection is industry-standard. For archived keys that were created on-premises before the migration, so that content that was previously protected by AD RMS can continue to be opened by the Azure Rights Management service post migration.
Azure Information Protection supports key lengths of bits and bits. For higher security, we recommend a key length of bits. For each document or email that is protected by Azure RMS, Azure RMS creates a single AES key the "content key" , and that key is embedded to the document, and persists through editions of the document. This tenant key is common to all documents and emails that are protected by the Azure Rights Management service for the organization and this key can only be changed by an Azure Information Protection administrator if the organization is using a tenant key that is customer-managed known as "bring your own key", or BYOK.
When you use a customer-managed tenant key BYOK , this security is enhanced by the use of an array of high-end hardware security modules HSMs in each Azure region, without the ability for the keys to be extracted, exported, or shared under any circumstances. To understand in more detail how Azure RMS works, let's walk through a typical flow after the Azure Rights Management service is activated and when a user first uses the Rights Management service on their Windows computer a process sometimes known as initializing the user environment or bootstrapping , protects content a document or email , and then consumes opens and uses content that has been protected by somebody else.
After the user environment is initialized, that user can then protect documents or consume protected documents on that computer. If this user moves to another Windows computer, or another user uses this same Windows computer, the initialization process is repeated.
Before a user can protect content or consume protected content on a Windows computer, the user environment must be prepared on the device. This is a one-time process and happens automatically without user intervention when a user tries to protect or consume protected content:. What's happening in step 1: What's happening in step 2: One of these certificates is the rights account certificate, often abbreviated to RAC. This certificate authenticates the user to Azure Active Directory and is valid for 31 day.
The certificate is automatically renewed by the RMS client, providing the user account is still in Azure Active Directory and the account is enabled.
To make things easier for you and newbies, Pocket-lint has compiled this guide. By the end of it, you'll know every facet of the app. And when the next update arrives, be sure to check back here for details. Snapchat is a mobile app for Android and iOS devices.
One of the core concepts of the app is that any picture or video or message you send - by default - is made available to the receiver for only a short time before it becomes inaccessible. This temporary, or ephemeral, nature of the app was originally designed to encourage a more natural flow of interaction. It claims to be a camera company. As such, it creates other products, including hardware, like Snapchat Spectacles, which you can read all about from here.
Also, Snapchat is colloquially referred to as Snap. Snapchat even lets you store media to a private storage area. Other features include the ability to add filters and AR-based lenses to snaps and show your live location on a world map.
But the key thing to realise about Snapchat is that it is all about instant communication through your mobile phone. Prior to Snapchat, social media was very desktop-based, and it was all about accumulating data.
For instances, you'd post statuses, tweets, photos, and videos, and you'd have a record of all those things online, so your friends could comment on them and you would all see them forever. Snapchat has changed that.
It changed the way we communicate online. With Snapchat, you can quickly send a photo of yourself with a rainbow-puking AR lens applied to a friend, and after they open it, it'll disappear forever. Technically, they can screenshot it if they want, and reply back with their own photo or video response, which they can also broadcast to their story for friends and followers to see.
There are so many uses for this app. Many reports and studies have claimed that the bulk of those users are millennials. This is the Camera screen. Now, how it looks and what options it shows may change over time, but generally, you will see a capture button at the bottom, with buttons to access your Memories screen, Chat screen, and Stories screen.
At the top, you might also see options to access your Profile screen, Search screen, and maybe even turn on the flash or switch your camera view to front-facing.
