Well it doesnt really matter...i have a MacBook and i just put it to sleep...so i dont tink its nessisary..but if ur like travelling wit it its safer it shut down ur computer...im my opion!
Which action can reduce the risk of ESD damage when computer equipment is being worked on?
If you properly ground yourself by using a antistatic bracelet (or if you don't have one, just use your hands) to make contact to a unpainted portion of the computer case/chassis (or even the power supply) to discharge any stored electrostatic charge that is on your body.

What file format is the common format for saving animated images?
- GIF
- APNG
- WebP
The most common format for saving animated images is the GIF format. GIF is the standard format for compressing images with flat color and crisp detail, such as line art, logos, or illustrations with type. Optimizing an image as a GIF format relies on lossless compression, which preserves all the data. However, GIF has some limitations, such as a maximum of 256 colors per frame and no support for transparency.
There are other formats that can save animated images, such as APNG, WebP, AVIF, MPEG, and WMV.
These formats may offer better compression, higher color depth, transparency, or other features than GIF. However, they may not be as widely supported by browsers or programs as GIF.
APNG vs GIF
The advantage of APNG over GIF is that APNG can support more features and better quality than GIF. Some of the main advantages are:
- Alpha channel: APNG can provide variable transparency for each pixel, while GIF can only have one transparent color per frame.
- Color depth: APNG can support up to 24-bit color, while GIF is limited to 8-bit color.
- Compression: APNG can compress better than GIF in most cases, reducing the file size and bandwidth usage.
There are several methods to convert GIF to APNG:
- Manual Conversion: If you want to convert GIF to APNG manually, you will need to extract the frames of the GIF file and save them as PNG files. Then, you will need to combine the PNG files into an APNG file using a program that supports APNG creation. For example, you can use GIMP or Photoshop.
- Online Conversion: There are many online tools that can help you convert GIF to APNG with just a few clicks. For example, you can use EzGIF (ezgif . com/gif-to-apng) or Vertopal (vertopal . com/en/convert/gif-to-apng). For visit, Make sure to remove spaces from the url.
- Offline Conversion: There are also some programs that you can download and install on your computer to convert GIF to APNG. For example, you can use ImageMagick or FFmpeg.
WebP vs GIF
The advantage of WebP over GIF is that WebP can offer better quality and smaller file size than GIF. WebP is a newer format that supports both lossy and lossless compression, meaning it can reduce the amount of data without affecting the image quality too much. WebP also supports 24-bit color and 8-bit alpha channel, meaning it can display more colors and transparency than GIF, which is limited to 8-bit color and 1-bit transparency.
Using WebP instead of GIF can save bandwidth and storage space, as well as improve the loading speed and performance of websites. However, WebP is not as widely supported as GIF, especially by older browsers and programs. Therefore, it may not be the best choice for some users or platforms.
Best way to convert GIF to WEBP is gif2webp. This is a tool that can convert a GIF image to a WebP image. gif2webp is a part of the WebP project, which is developed by Google to make the web faster by using more efficient image compression. You can use gif2webp to create WebP images from GIF files, and adjust the compression options to suit your needs.

Charles Babbage is considered as "father of the computer", Babbage is credited with inventing the first mechanical computer that eventually led to more complex designs.
How can you read books on your computer?
There are websites you can go to. Some require that you have a PDF reader such as AdobeReader but some don't. Some have books you can download to your computer. See the Related Links.
Who is known as the father of modern digital programmable computer and why?
Charles Babbage because he invented the "Difference Engine."
Name of the all super computers?
There is a list of companies that used to make super computers and some of those companies still do make super computers. The question is simply but the answer keeps changing on a day by day basis especially if you include the military super computers. IBM and Toshiba make that size of computer.
When was the Colossus computer built?
The actual computers called Colossus were World War II code-breaking computers built in 1943 and 1944 in Bletchley Park, Buckinghamshire, England. These were the first true programmable computers, and about a dozen were built.
The prototype, Colossus Mark I, was shown working in December 1943 and was operational at Bletchley Park by February 1944. An improved Colossus Mark II was first installed in June 1944, and ten more had been constructed by the end of the war. Unfortunately, the secret nature of these computers meant that their innovations were not available for commercial computer development for many years.
*The other computer called Colossus is a fictional artificial intelligence from a 1965 novel (Colossus) by Dennis Feltham Jones, which was the basis for the film Colossus, the Forbin Project in 1970
What is computers significance today?
Computers are universal tools; we can use these tools to improve our lives in a variety of fashions. Humanity has already implemented computers in daily use items from calculators for assistance mathematics to automobiles for transport.
What are the uses of computers in your community?
They are at my school to take tests and do projects, for instance.
Are computers becoming teachers of humans?
NO, humans created the computers and humans put the information on the computers the computers have no thinking ability what so ever... the information you see on a website that you learn from is not the computer teaching you its the person who created the site that is teaching you.
Did they have computers in the 1900's?
no, first 'computer' was invented in 1959. There were no electronic computers in 1912. For one thing, the science of electronics as we know it had barely started. Even radio broadcasting was still in its infancy, with most "wireless" communications consisting of Morse code broadcasts - not voice or music. There were some simple analog computers, which were mechanical devices that could be made to perform simple fixed calculations for things such as navigation and aiming military weapons. The concept of the computer as we know it, with the idea of a stored program and input/output stages actually dated back to the 19th century when a British inventor named Babbage laid out the design of a programmable mechanical computer. However the metalworking techniques of the day weren't accurate enough to allow his machine to function properly. It was not until the late 1930s that work on computers as we know them began, partly due to the need for increased calculation speeds due to progress in physics and chemistry, and significantly due to wartime needs in cryptography, aerial bombing, and signal processing. True commercial use of electronic computing didn't begin until the 1950s, and personal computers as we know them took another 20 years or so to reach the marketplace.
For more information look up some of the following (just a very tiny sampling!)
People - Babbage, Turing, Eckert, Mauchly Machines - Whirlwind, Enigma, Eniac, Zeus Other topics - Cryptography, Bletchley Park, IBM, Sperry-Univac
Why computer is known as electronic device?
Only because that is the best technology currently available to build them with. Many computers have been proposed and/or designed and/or built with other technologies, a few of which are (with an example if possible):
- mechanical - Babbage's Analytical Engine, designed but never built and Zuse's Z-2
- electromechanical - Aiken's Harvard Mark I and IBM's SSEC and Zuse's Z-3
- hydraulics/fluidics - proposed for use in high radiation environments (nuclear reactors, satellites, etc.), some prototypes built in 1960s
- optical - possible future replacement for electronics, prototypes still in development
- holographic - still largely hypothetical proposals
- quantum - very limited prototypes built but promises an unlimited increase in processing speed
- etc.
When did they create the computers?
- The first electronic digital computer was built in 1942. Called the ABC it was built in Ames, IA by John Vincent Atanasoff & Clifford Berry.
- The first programmable electronic digital computer was built in 1943. Called Colossus Mark I it was built by Thomas Flowers and a team at the Dolis Hills lab of the British Post Office for Bletchley Park. Through 1944 and 1945 up to the end of the war in Europe 10 more Colossus Mark IIimproved models that used parallel processing to run 5 times faster were built.
- The first programmable electronic digital computer using a stored program (like all modern computers) was built in 1948. Called the Manchester Baby.
Who are the two most powerful and important men in computer history?
A few years back, many would have said Bill Gates of Microsoft and Steve Jobs of Apple. However, Steve Jobs passed away and Bill Gates is no longer a part of Microsoft. Early in 2015, Bill Gates completely retired from Microsoft. He retired as CEO around 2000 and as Chairman in early 2015.
Most powerful type of computer?
Supercomputer, to classify as such a system must have at least 10 times the performance of the highest performance conventional computers.
Where do you buy a supercomputer?
They are not commercially sold, the power supply needed would probably also mean you would need to upgrade your power supply. Just buy a commercial computer.
People use computers inside of schools for many reasons, teachers may use them for typing up tests, grading, and streaming videos for educational purposes. Students might use them to create and work on projects (I.E Powerpoint,Movie,Excel ect.) or take tests on currently read books to gain points in the classroom.
How much gold is in a computer processor?
Not much, since the gold is typically just a thin plate over copper traces. Printed circuit gold is usually only one or two mils thick and you'd need several boards to make up an ounce of gold. It IS worth it, but you'd need to process several boards to make it worth your time and effort.
What are 3 benefits of computers?
Lot of them to state. please advice what exactly are you looking for. If there were no computers, we would have been interacting on WIKI
ANSWER: Where to start and where to finish for the benefits. perform arithmetic. make logical decisions, communication withe the whole world, control machines at precise points. Allow information to be seen instantly and on and on. Unfortunately is a dumb animal it is as smart as the MAN that programs it thank go. Huh
What was the purpose of making the first electronic computer?
The first electronic computer, the Atanasoff Berry Computer, was invented because Doctor John Vincent Atanasoff at the University of Iowa in Ames Iowa had too many large difficult to solve systems of simultaneous equations. The machine was invented one night in a bar in Indiana where Atanasoff had gone to get away and the ideas started coming together. It was built between 1939 and 1942. Atanasoff designed it to solve systems of simultaneous equations of up to 29 variables, because this would handle most of his problems without having to make the machine too big (it came out about the size of an office desk).
