How many hamming bits are required for a single EBCDIC character?
To represent a single EBCDIC character, typically 8 bits are required. However, to ensure error detection and correction, additional parity bits known as Hamming bits are added. In the case of a single EBCDIC character, typically 4 Hamming bits are added, resulting in a total of 12 bits to represent the character. These Hamming bits help detect and correct errors that may occur during transmission or storage of the data.
What is the similarity and difference between internet and intranet?
Internet & Intranet Similarities
They are interconnected computers
They use cables and/or satellites to connect
Internet & Intranet Differences
Internet essentially needs an internet service provider(isp)
Intranet normally uses isp as a service to connect to the internet but doesnt need one to exist
Internet is open to all
Intranet is for a specific organization/group of people/professionals
Internet doesnt essentially need a leased line
Intranet normally uses a leased line for security
What does XHTML stand for and what is it used for?
XHTML stands for Extensible HyperText Markup Language.
It is a language that branches off of HTML, combining the use of XML syntax with HTML markup; all tags and attributes must be lowercase, all tags must be closed, and tags must be nested properly (as to not overlap one another in a shift).
The requirements to comply with XHTML standards force the use of CSS in the place of specific tags to establish cross-browser compatibility on styles. These standards are issued by the W3C.
XHTML is compatible with all (if not, most) modern browsers.
What is called the eye of the computer?
The "eye of the computer" is typically referring to the webcam or camera on a computer or other electronic device. This camera allows for video conferencing, taking pictures, and recording videos. It is an essential component for communication and multimedia purposes in modern computing devices.
What is the function of communication devices?
Communication devices serve the purpose of transmitting data, information, and messages between individuals or systems. They allow for the exchange of information through various means such as voice, text, or multimedia. These devices can include smartphones, computers, tablets, and other hardware that enable connectivity and interaction between users. Ultimately, communication devices facilitate effective and efficient communication in both personal and professional settings.
What is the css code for posting a picture?
To post a picture using CSS, you typically use the background-image property. Here’s an example:
css
.image-container {
width: 300px; /* set width */
height: 200px; /* set height */
background-image: url('your-image.jpg'); /* specify image URL */
background-size: cover; /* ensure the image covers the container */
background-position: center; /* center the image */
background-repeat: no-repeat; /* avoid repetition */
}
In HTML:
html
Copy code
This CSS code sets a background image for a container and ensures it's centered, scaled, and non-repeating.
The conservation of information law is important in data science and information theory because it states that information cannot be created or destroyed, only transformed. This means that data cannot be lost or gained without a corresponding change elsewhere in the system. Understanding this law helps in ensuring the accuracy and integrity of data analysis and processing in these fields.
What are 1e18 1e15 1e12 1e9 etc?
That's just another way to write numbers in scientific notation. The other common way to express scientific notation is 1 X 1018, 1 X 1015, 1 X 1012, etc. All that means is that the number before the exponent is either followed by the number of zeroes in the exponent (if the exponent's positive), or proceeded by the number of zeroes in the exponent (if the exponent's negative).
In the sciences, the first several exponents that are non-zero multiples of 3 (both positive and negative), are given special prefix names. For example, 103 is kilo-, 109 is giga-, and 10-9 is nano-.
Below, I added a related link that gives many more examples of these special prefix names.
What is the difference between A level and O level?
The"General Certificate of Education 'Ordinary' Level Examination", otherwise known as the "GCE 'O' Level" or the "O Levels" is the examination taken by students of Secondary Education in the United Kingdom, Commonwealth countries or regions associated with the British curriculum. The "GCE 'O' Level" is a subject-based qualification.
The "GCE 'O' Level" functions as to determine the standards of middle-secondary students and usuallynot required in the entry to college.
This usually encompasses students of Grade 8 to Grade 10.
The "General Certificate of Education 'Advanced' Level Examination", otherwise known as the "GCE 'A' Level" or the "A Levels" is the examination taken by students of Post-Secondary Education or Pre-University Education in the United Kingdom, Commonwealth countries or regions associated with the British curriculum. Similar to the "GCE 'O' Level", the "GCE 'A' Level" is also a subject-based qualification.
The "GCE 'A' Level" functions as to determine the standards of post-secondary students and is an internationally-recognized qualification to enter recognized colleges or universities.
This usually encompasses students of Grade 11 to Grade 12.
What are the four stagesof the cell cycle?
There is Gap1 (G1 stage) where the cell is when it's not dividing. Then Synthesis (S stage) where the cell's DNA is duplicated. After that you have Gap 2 (G2 stage) where the cell gets ready to divide. Then the cell divides in mitosis. It ends with cytokinese where the cytoplasm splits and the plasma membrane disconnects.
What are the factors to consider when selecting a map scale?
1). How much total real-world area you want to show.
2). What size piece of paper you want to show it on.
Is 1 GB bigger than 256 MB and if so why does the 256 MB memory card cost more on Amazon?
Yes, 1 GB is bigger in capacity than 256 MB. The cost of a 256 MB memory card on Amazon may be higher due to factors such as rarity, demand, brand, or specific features offered on that particular memory card.
How do you define the unit prefixes deci centi milli micro nano pico?
Deci represents 1/10, centi is 1/100, milli is 1/1000, micro is 1/1,000,000, nano is 1/1,000,000,000, and pico is 1/1,000,000,000,000. These unit prefixes are used in the metric system to denote multiples or fractions of a base unit.
How do you define the unit prefixes Tera Giga Mega kilo hecto deca?
Tera represents 10^12, giga represents 10^9, mega represents 10^6, kilo represents 10^3, hecto represents 10^2, and deca represents 10. These prefixes are used to indicate multiples of 10 in the International System of Units (SI).
A mega earthquake is an extremely powerful earthquake, typically with a magnitude of 9.0 or higher on the Richter scale. These rare but catastrophic events can cause widespread destruction, tsunamis, and loss of life in the affected area.
What is the difference between operating environment and operating system?
operating environment is the interface in which you work while operating is the platform on which your computer runs
An operating environment is an operating system with no user interface so you need to use the command prompt to do things like:
open/word/
Then the word processing program will open and you can use it.
What are non-Windows applications?
Some examples of Microsoft Windows applications are:
- Microsoft Excel
- Microsoft Internet Explorer
- Notepad
- Mozilla Firefox
Which option properly summarizes the inputs and outputs of the Calvin cycle?
1. 6 carbon dioxide molecules combine with six 5-carbon molecules forming twelve 3-carbon molecules.
2. The 12 3-carbon molecules are converted into high-energy forms.
3. 2 of the 12 3-carbon molecules are removed and the plant uses them to produce sugars, lipids, amino acids, and other compounds.
4. The 10 3-carbon molecules What_are_the_four_steps_in_the_Calvin_cycleback into six 5-carbon molecules, which combine with 6 more carbon dioxide molecules.
The process starts over.
What separates a workseet reference from a cell reference?
A cell reference points to a specific cell in a spreadsheet using its row and column labels (ex: A1). A worksheet reference refers to a different worksheet within the same spreadsheet (ex: Sheet2!A1), allowing you to pull data from or perform calculations with cells in another sheet.
What does the greek word 'atmos' mean?
