Difference between Megabyte and Gigabyte
You've probably heard the terms megabyte and gigabyte thrown around a lot, but what do they actually mean? And more significantly, how do the two differ from one another? In comparison to one gigabyte (GB), one megabyte (MB) is equivalent to 1, 000 kilobytes. Therefore, when comparing sizes, a GB is significantly bigger than an MB. Gigabytes are larger, while megabytes are smaller. While the majority of users don't require more than one gigabyte of storage on their computer, if you're a power user or frequently work with huge files, you could. Don't worry, we're here to help. Below, we'll ...
Read MoreDifference between PGP and GPG
PGP and GPG are both very powerful tools for encrypting your data. Some differences are there between the two which you should be aware of before making a decision about which one to use.

Read MoreDifference between UAV and RPV
Remote-controlled vehicles are often used for tasks such as surveying land or inspecting pipelines. They can also be used for search-and-rescue missions or to deliver supplies to people in need. Unmanned aerial vehicles, on the other hand, are typically used for military purposes. Unmanned aerial vehicles (UAVs) and remotely piloted vehicles (RPVs) may seem like they're one and the same, but there are some key differences between the two. It's important to know the difference for a few reasons: first, if you're looking to purchase one of these vehicles, you'll want to make sure you buy the right one for ...
Read MoreHow to escape any special character in Python regular expression?
Regex, often known as regexp, is a potent tool for finding and manipulating text strings, especially when processing text files. Regex may easily replace many hundred lines of computer code with only one line. All scripting languages, including Perl, Python, PHP, JavaScript, general-purpose programming languages like Java, and even word processors like Word, support Regex for text searching. Regex may be challenging to learn because of its complicated syntax, but it is time well spent. Special Characters Text processing becomes more challenging when special characters are included because context must be carefully considered. You must think about what you see, ...

Read MoreHow to Get a List of Current Open Processes Java?
It is essential for the user to know about the processes that are running in their system, be it foreground or background. To do so in windows we have a task manager but internally it uses a program called tasklist. Tasklist aside from giving us the currently running processes, it also gives us details like process id, session name, session and memory usage of each process. In this article we will see how we can get a list of currently open processes by using Java programming language. Algorithm Step 1 − Create a process that executes the tasklist.exe Step 2 ...
Read MoreHow to draw an Image with drawImage() in HTML5?
The "canvas" element merely serves as a container for visuals; drawing the graphics requires the use of a scripting language. It is a procedural, low-level model without an internal scene that updates a bitmap. The drawImage() function is what we employ to draw an image onto a canvas. This feature transfers a video, canvas, or picture to the canvas. Syntax context.drawImage(img, x, y, swidth, sheight, sx, sy, width, height); Where, Img − Determines whether to utilise a video, canvas, or image. Sx − The starting x coordinate for clipping. Sy − The y point at which clipping should ...
Read MoreGolang program to implement returning pointer from a function
In this article, we will write Golang programs to implement returning pointer from a function. A pointer stores the address of another variable and the address is depicted using & operator. Algorithm Step 1 − Create a package main and declare fmt(format package) package in the program where main produces executable codes and fmt helps in formatting input and Output. Step 2 − Create a function create_pointer that returns a pointer to the int Step 3 − Set the value of x in the function and return the variable back to the function Step 4 − Create a main ...
Read MoreGolang program to parse time
In golang we can use various internal time function to parse time. Time is parsed using parse and ParseInLocation method. Syntax time.Parse() This function belongs to time package. It is used to parse the string into time.Time value and it takes two inputs: the layout and the time string which is to be parsed. time.ParselnLocation() This function is a part of the time package. It is used to parse the string into time.Time value along with a specified location. It takes 3 arguments: the location, layout string and the time string. time.Format() This function is present in ...
Read MoreGolang program to implement select statement
The Golang Select statement is similar to the switch statement, the switch statement selects the Output based on the cases but here the Output is selected based on which communication occurs fast in the channels. Syntax func make ([] type, size, capacity) The make function in go language is used to create an array/map it accepts the type of variable to be created, its size and capacity as arguments. time.Sleep() This function belongs to the time package. Here, the word sleep depicts the meaning of the function which says that it will block the execution of goroutine for ...
