how often does windows automatically defragment a hard drive or trim a solid-state drive
If there is extraordinary fragmentation that is getting close to the "maximum fragmentation threshold," Windows will automatically consider partially defragmenting an SSD once a month.
In this post, we define defrag and discuss why doing it on an SSD is often a terrible idea.
However, that is a pretty straightforward response to a much more complex reality that most websites and forums get incorrect. If you want to know that, when left to Microsoft, defragging and optimizing an SSD are both excellent things, keep reading this article.
It saves time, energy, and wear and tear for disk read heads to not have to skip around your spinning disk in search of all the pieces by moving the thousands of file parts into sequential order during defragmentation of a spinning hard drive.
However, if there is extraordinary fragmentation that is getting close to the "maximum fragmentation threshold," Windows will automatically consider partially defragmenting an SSD once per month. After that point, the SSD will stop reading and writing because the "meta data" for the file fragments is too much for the SSD to manage. Microsoft will cautiously defrag the seldom potentially dangerous files because this is a negative thing.

Computer BotsCommand & ControlWhat are computer bots?A computer programme known as a "bot," short for robot, executes automatic, repeated operations. Usually, bots mimic or take the place of human users. As automated systems, they perform tasks considerably more quickly than do consumers who are humans.
Which types of bots are there?Bots come in two flavours: good bots and bad bots, both of which are relevant to web security. Both make attempts to use web resources (such as websites, web applications, APIs, etc.) or carry out other normal human user actions on the web, but for quite different reasons.
How do computer bots work?A bot (short for robot) is a software application programmed to perform tasks through Robotic Process Automation, or RPA. Bots work by automatically going through a set of instructions, and they carry out tasks and processes much faster, more accurately, and at a higher volume than it would otherwise take humans.

in java, when a character is stored in memory, it is actually the ________ that is stored.
In java, when a character is stored in memory, it is actually the Unicode number that is stored.
Every character in Unicode has a unique number, regardless of the platform, language, or software it is used with. There were hundreds of distinct encoding techniques for allocating this number prior to the creation of Unicode. Not enough characters could fit in a single encoding: To cover all of its languages, for instance, the European Union alone needs a number of distinct encodings.
No one encoding was sufficient for all the letters, punctuation, and technical symbols in regular usage, not even for a single language like English. Additionally, several encoding techniques clash with one another. The same number may be used by two distinct encodings for two different characters or by a single character in both.
Data always runs the danger of damage when it is transferred between multiple encodings or platforms, even if any particular computer (especially servers) needs to support a wide variety of encodings.
Both students and working professionals can benefit from our fundamental Java programming tutorial. Java is a general-purpose, concurrent, secured, object-oriented, class-based, and computer programming language. It is an established, reliable technique.
A platform is any hardware or software environment in which a program is run. Java is referred to as a platform since it has a runtime environment (JRE) and an API.

3. What is a process in software engineering
a program to search words in c++
Answer:
a starting point might be after you get this working, you can allow them to enter more words and iterate your search,
for each argument (not counting the first one that is the file name)
search for the word, show the lines...
and more files too, for that matter, for each file, for all the words... (at this point you MUST put flags on what each thing is, up to now, you can use the order of args)
just note that arg[] are c-strings. you can assign a string a c-string, so promotion lets you do things more normally, or you can process it as-is depending on what you use it for (see how I just used it in the file name but moved it to a string in the target?).

A project is any individual or collaborative undertaking, possibly involving research as well as design, that is carefully planned to achieve a specific goal. An alternative viewpoint regards a project as a series of events: a "set of interrelated tasks to be completed over a fixed period of time and within certain cost and other constraints." A project is a temporary (rather than permanent) social system (work system) that may be staffed by teams (within or across organisations) to complete specific tasks under time constraints.

Explanation: Worms are self replicating. Worms also don’t need a host computer to run like viruses do.
Assume that c is a char variable that has been declared and already given a value. Write an expression whose value is true if and only if c is what is called a whitespace character (that is a space or a tab or a newline-- none of which result in ink being printed on paper).
The expression whose value is true if and only if c is what is called a whitespace character is ( c == " II c== '\n' || c == '\t').
The "white-space character" space, tab, line feed (newline), carriage return, form feed, and vertical tab serve the same function as the spaces between words and lines on a printed page: they facilitate reading. White-space characters and other tokens, including operators and punctuation, serve as token delimiters (bounded spaces).
The C compiler ignores white-space characters while parsing code unless you use them as separators, as parts of character constants, or as literal strings. To make a program easier to read, use white space characters. Take note that comments are also treated as white space by the compiler.
Any character or string of characters used to represent horizontal or vertical space in typography is known as whitespace in computer programming. A whitespace character usually takes up space on a page even though it does not correlate to a mark when it is rendered.
For instance, the standard whitespace symbol U+0020 SPACE (also known as ASCII 32) is a punctuation mark for a blank space that is used to separate words in Western scripts.
