Why do primitive types have ranges of values? what determines the range of the data type?

Answers

Answer 1

What determines the range of primitive data types is a combination of the number of bytes that is allocated to them and if there's any encoding.

Not too long ago, it was normal for an integer to receive four bytes of memory. An unsigned integer would also receive four bytes of memory. The unsigned int had a range of 0 - (2^32 - 1) because it could only be used for positive integers and could use all 32 bits. An integer has a range of (- 2^31 through +2^31 - 1). The 32nd bit is uses as a sign bit (0 for positive, 1 for negative).

Just for thoroughness: when an int is negative, it's stored as the two's complement of it's absolute value.

âthe first line in a hypertext markup language (html) file is the _____, which is a processing instruction indicating the markup language used in a document.

Answers

This is usually not needed anymore in the updated versions of HTML 5.

Answer:

The first line in a hypertext markup language (html) file is the Doctype, which is a processing instruction indicating the markup language used in a document.

The correct answer is:

Doctype

Explanation:

The Doctype is the abbreviation for document type declaration which is an instruction related to XML and SGML documents that makes them adopt a document type definition to be shown as an element compatible in that format. In other words, it allows them to be from one type and be translated into another type without visual or presentation modification. It is just to be more flexible, fast, and manipulable.

In one or more complete sentences, explain about vehicle maintenance and vehicle safety

Answers

Vehicle maintenance is important because without them the vehicle would not function properly and could be a safety hazard. Vehicle safety is important because without it we could end up seriously injured or even killed, vehicles can be very dangerous if handled irresponsible and the proper safety methods are not used.

Vehicle maintenance and safety are essential parameters for road and traffic safety. If vehicle is not working proper then it may cause serious damages like accident or may be death.

Further explanation:

Vehicle maintenance: This is very important to feel confident that your vehicle will function properly on the road. The easiest way to save the investment is through preventive maintenance. In preventive maintenance, keeping record is the main feature. This will include inspection, lubrication and repairing records. Everyone must know the mechanical condition of their vehicle. Before going for any trip, one should check the engine condition whether it is working properly or not. For this, start the engine and check that every instrument is giving normal reading or not. If it is not giving the normal readings then go to the service center and ask the mechanic to check the condition of the vehicle. Also, you must check the emergency equipment like fire extinguisher is charged or not and spare tire/wheel is okay or not.

Vehicle Safety: For vehicle safety, follow the below safety guidelines:

Wear your seat belt or helmet in case you are riding bike.Make sure your vehicle is working fineDon’t speed or drive more than the speed limit.Don’t drive imperfective.Use car seats for childrenDon’t drink and driveFollow traffic rules

What does limited access to a document mean?

It makes a document inaccessible without a password.
It enables a person to make changes and automatically save them.
It does not reflect any changes made in the document.
It enables a person to read the document but not edit it.
It blocks a person from accessing a document.

Answers

the second last one is the answer i think

Answer:

C). It enables a person to read the document but not edit it.

Explanation:

Limited access to a document is primarily associated with the creator of document restricting the usage and changes that can be made to a specific document. It assists the users to protect the authenticity of their document and prevent it from any unnecessary editing to the document. Therefore, the limited access to a document would imply 'enabling a person to only read the document but not edit or make changes to it' without the creator's permission. It is thus aimed to limit the access to a specific content. Therefore, option C is the correct answer.

The onion root looked slightly like a brick wall with tiny dots inside of it (the nuclei). The cell walls were not clear however the nuclei was very clear...Prophase: The chromosomes are condence and become visable for the very first time during this cycle. The fibers begin to form and the membrane begins to disintegrate.Metaphase: The fibers attach to the center of each sisters chromosomes. They then align in the center of the cell. The nuclear membrane disingrates completely. Anaphase: The center begins to split and the sister chromosomes then migrate towards the other sides of the cell.Telophase: The chromosomes are now clustered on both ends of the cell. The membrane is now reforming itself. The cell plate begins to form between both daughter nuclei. This is then followed by something called cytokinesis. I now changed my slides to the whitefish blastula.Viewing at a 400x magnification the cell shape stayed pretty much similar and they still had a circle like shape to them. In one certain cell, the chromosomes that had lined up in the previous stage, had broken apart from their duplicates and had headed into a different centriole. The stage the cell is now in is the anaphase. When observing the whitefish for the stage of telophase, the shape stayed the same as well except for one cell which is currently in the telophase stage. The cell that is in the different stage looked like two different circle cells that joined one another. This stage the chromosomes reached the center and a nuclear membrane than began to form around each nuclei. 30% of the cells are in the prophase stage5% of the cells are in the metaphase stage5% of the cells are in the anaphase stage5% of the cells are in the telophase stage35% of the cells are in a stage of mitosisIn this conclusion I see that the hypothesis is right. It states that cells will go thru multiple stages of mitosis in their lifetime and they surely do! It also states that we (the viewer) would be able to see the different slides in one stage of mitosis. We were able to see this as well. The other thing I would like to state is that the slides used for the microscope were not large or very clear, but it was good enough to sort of have the idea of what is going on. I have learned that both of the slides are continuously reproducing and creating new and different cells and I was able to learn how to calculate the percentage of cells in the different stages.. I was able to learn a lot from this experiment and I was also able to learn more about a microscope then what I already knew. If I could change this experiment I really would not in any way. It was simple and fun to learn about the different cells and the different ways that they move and the ways they reproduce.
