Today, I learned that it relates to math and it was quite interesting learning about codes I’d like to use and play with python, today’s lesson was quite easy and simple.
The int() function returns the numeric integer equivalent from a given expression. Expression whose numeric integer equivalent is returned. Using int() function we can convert the string input to integer. The below program will get two numbers from the user and print their sum. int() function converts any datatype to integer.
1. print(compoundClass[3]), type print(compoundClass[4])
2. compoundClass[5] will print nothing
3. compound class = [“alkanes”, “alkenes”, “alcohols”, “ketones”, “alkyl halides”, “alkynes”]
print(compoundClass[-1]
4. Prints compound class = [“alkanes”, “alkenes”, “alcohols”, “ketones”, “alkyl halides”, “alkynes”]
print(compoundClass[-2] alkyl
5. A positive number starts and progresses from an alkane, whereas a negative number is the exact opposite of a positive number, so it moves back and forth.
6. Prints out everything in compound class.Supercomputers fastly perform large and complex mathematical computations. Mainframe computers act as a server, store large databases and serve a large number of users simultaneously. Mainframe computers are also expensive but less than supercomputers. It provides the advantage of quick response. This type of operating system avoids duplication of software.
Digital Camera: Taking photos or selfies
Mobile phones: allows users to make and receive calls over a radio frequency link while moving within range of the phone.The resource is a material or a supply that we need in our environment.
Hard drive- The hard drive is where all your permanent computer data is stored. Whenever you save a file, photo, or software to your computer, it is saved to your hard drive.
Operating systems- Software that supports basic computer functions such as scheduling tasks and, running applications.
CPU- The part of the computer that retrieves and executes commands.
So the CLI provides greater flexibility of use. It can be used to easily do things that are difficult or even impossible to do with a GUI. A GUI needs to use additional system resources to load the graphical part thus it is going to be slower than using the command line. GUI users have Windows that allow a user to work, view, control, and manipulate multiple programs and folders at the same time. CUI does not offer the same ease and ability to work with multiple programs at once on one screen.
My favorite is Windows because, to be honest, I have never used any of them except for Windows. For example, you can use Windows to browse the Internet, check email, edit digital photos, listen to music, play games, and more. Windows is also used in many offices because it provides access to productivity tools such as calendars, word processors, and spreadsheets. Microsoft Windows, also called Windows and Windows OS, computer operating system (OS) developed by Microsoft Corporation to run personal computers (PCs).
Run length Encoding uses the same amount of space, it is a lossless compression it replace a sequence of number or characters.
1.File compression is when the size of file or information getting smaller. It reduces space of the file.
2.Lossless is when the file can be restored and remains. Lossy means when the file cannot be restore and loses the quality.
3. GIF, PNGA VPN can prevent web browsers and others from accessing your connection, helping to keep the information you send and receive anonymous and secure.
VPN can be used for security or maybe business for a company’s internal network or to the public internet. For example like Netflix, if you use VPN you can change the location and it can protect your private informations. It allows you to create a secure connection to another network over the internet.Symmetric encryption uses a single key that needs to be shared among the people, asymmetric encryption uses a pair of public key and a private key to encrypt and decrypt messages when communicating.
I think it’s because their security is weak, to prevent hackers I think we should make our passwords more complicated.
British airways had technical issues and affecting the check-in systems, leaving passengers with little information about their flights and electronic tickets.
