Answer:
six levels
Explanation:
HTML defines six levels of headings. A heading element implies all the font changes, paragraph breaks before and after, and any white space necessary to render the heading. The heading elements are H1, H2, H3, H4, H5, and H6 with H1 being the highest (or most important) level and H6 the least.
Uninstall And Reinstall Maybe Or You Might need to update that's all I know
Answer:
The answer is "Option a, and c".
Explanation:
Following are the description of the Digital Signature choices:
- To change the physical transportation of paper or link files in the computerized messaging system, some processes should be identified and utilized in digital signatures, which enables documentation to be validated unforgivably.
- Using public-key cryptography, digital signatures, that's an exquisite system, that's why options a and b are correct.
- Digital signatures are not a central authority, that's why the option B is wrong.
Hey there! Hello!
So, not sure if there's actually a button to "close out" a window to where you're able to reopen it again without having to go to where the file is located or go to recents in your application. Keep in mind that I'm on a MacBook, but I have worked on a Windows computer before.
One thing you can do is minimize the window. Your program will remain open, but your window will remain out of your way until you decide to expand it again. This seems to be the closest thing possible to your description, but if you had something else in mind, I'd love to hear more details.
This won't be a good solution if you're looking to cut down on the energy that certain programs may be taking up while open, even if you're not using them. But in terms of getting the windows off your desktop, minimizing is the way to go. It also allows you to have documents/windows out of the way while still being able to work on other documents/windows in the program (i.e. Microsoft Word, Google Chrome, Pages, etc.)
Hope this helped you out! Feel free to ask me any additional questions you may have. :-)
Answer:
Explanation:
The arithmetic logic unit (ALU) performs mathematical, logical, and decision operations. It can be divided into the arithmetic unit (responsible for addition, subtraction, multiplication and division). And logic unit (responsible for comparing, selecting, matching and merging different data or information). The power and efficiency of the CPU depends on the design of the ALU.
Next up is the control unit (CU) which directs all the processor’s operations. It’s where the CPU reads and interprets requests from memory and transforms them into a series of signals (binary). Then it sends the operation to various parts of the laptop as instructed. The CU calls the ALU to perform the necessary calculations. It also coordinates all input/output devices to transfer or receive instructions.
The main job of the memory unit is to store data or instructions and intermediate results. It’s divided into primary memory and secondary memory to supply data to other units of the CPU. It allows the CPU to perform functions requested by programs like the operating system without having to ask RAM.
Another element of the CPU not depicted in the diagram is transistors. To carry out calculations, binary information (ones and zeros) is stored in these microscopic switches. They control the flow of electricity depending on whether the switch is ON or OFF. Signals turn off and on different combinations of transistors to perform calculations. A very thin silicon chip can contain several hundred million transistors.
