Answer:
Hydrogen.
Explanation:
Hydrogen is the simplest element that exists. The symbol for the chemical element Hydrogen is "H" and it is a colourless, tasteless, odorless, and highly flammable gas.
Hydrogen is a chemical element found in group (1) of the periodic table and as such it has one (1) electrons in its outermost shell. Therefore, Hydrogen has an atomic number of one (1) and a single valence electrons because it has only one proton and one electron in its nucleus.
Additionally, all stars are made up of Hydrogen.
A star is a giant astronomical or celestial object that is comprised of a luminous sphere of plasma, binded together by its own gravitational force. Stars are typically made up of two (2) main hot gas, which are Hydrogen (H) and Helium (He).
A student is curious about how a Web site appears on his computer screen. There is a communication between the client and the server in the Application Layer.
Explanation:
- When we choose to open a webpage (in any browser) the seventh layer of the OSI model - called Application layer will help to do that.
- What happens after we write the webpage address in address bar is that the Application layer protocol (also called HTTP) formats and sends the request from the client's browser (Internet Explorer, Mozilla Firefox , Opera, Safari etc.) to the server.
- It also formats and sends the server's respond back to client's browser. This process happens very fast and all the OSI model layers are processing in it (not only the Application layer).
- All the layers are working together and each of them is responsible for some particular job, but all together they work as one. The layers communicate with each other and in case of error they will retry and fix the error or if they are unable to do it, the responsible layer will inform the user about the source of the problem.
- What happens when page is requested and received? If we will remove the graphical and visual image and look at the process that computer does. We will see a set of commands, mathematical algorithms, symbols, letters and not understandable codes and processes.
- When data is sent from "A" to "B", a transport layer is responsible to send and deliver it correctly and exactly the same, what was requested.
- If the request, processed by "A" (sender) is too long, the transport layer will divide it in segments (called segmentation process) to understand well and not make a mistake while sending the data to "B" (recipient). After this process data is travelling through the network to the "B" (recipient), if the sent data is segmented or divided, the transport layer is responsible for reassemble it again and "B" (recipient) receives its requested data (It can be web page or other data).
- If the transport layer will not do the segmentation process, then the next - network layer - will check the data and if the requested message is too long it will fragment it (called fragmentation process) and will provide the same as transport layer had to do.
- All the layers processes are connected to each other and work cooperatively.
Answer:
The two ways the calendar meets the criteria of showing the correct date are;
1) The calendar can give dates in the 12 months in a year
2) The calendar can show up to the 31 different days in a month
Explanation:
The two ways in which the calendar meets the criteria of showing the correct date are;
1) The number number of long blocks with 4 different months each = Three
Therefore, the total number of months the blocks can hold = 3 × 4 months = 12 months = The number of months in a year
2) The number of faces on each dice = 6 faces
The number of dice = 2 dice
The total number of faces = 12
The number of identical faces = 2 (11th and 22nd of the month)
The number of unique faces = 10
The number of combinations of the dices = ₁₀C₂ = 45
The number of combination of faces required to show = 1 to 31 = 31 combination
Therefore, there are adequate combinations on the dice to show all the dates of month
function is the right answer because function is a block of code designed to perform a particular task
