Do you know about LINUX ????

LINUX:-
....................................................................................

Linux is an open source computer operating system designed primarily for the PCs. Linux was designed considering Unix compatibility . It's functionality list is quite similar to that of Unix. One of the most valued advantage of Linux over the other platforms lies with the high security level it ensures.

ADVANTAGE OF LINUX:-
............................................
1.PORTABLE:-It can work on different types of hardware in same way.
2.OPEN SOURCE:-Linux source code is freely available.
3.Multi-User :-Linux is a multi-user system I.e multiple user can access system resources like MEMORY/RAM/application programs at same time.
4.Multi-programming:-Linux is a multi-programming system which means multiple application can run at the same time.
5.Hierarchical file system:-Linux provides a standard file structure in which system film/user files are arranged.
6.Security:-Linux provides user security using authentication features like password  protection/controlled access to specific files/encryption of  data .

DISADVANTAGE OF LINUX:-
  1. Some hardware and software may not be compatible with a particular version of Linux.
2.Linux require a strong learning curve to understand ,as all the commands are to be learned with syntax.
3.installition and uninstallation of softwares is slightly tough task.
4.It is a case sensitive operating system I.e. commands should be written with concentration.

What is an E-mail???

E-mail:-
                 Electronic mails can be defined as asystem for sending and receiving messages electronically over a computer network. Today's email systems are based on a store and forward model. Email servers accepts,forward,deliver and store messages. Email is a system of world wide electronic communication in which a computer user can compose a message at one terminal that can be regenerated at the recipient's terminal,when the recipient Login.

      Email allows user's to communicate with each other in less time and at nominal cost as compared to traditional phone or mail services. There are many software platform available for sending and receiving Email.

ADVANTAGE &DISADVANTAGE:-
          Email can be sent anywhere in the world to anyone who has an Email address.
To save the time and money,more and more people are using Email.
                     However,the slight error in the address can deliver the mail to the wrong address . Hence,Email comes with it's own share of benefits and limitations.
 
SPAM MAILING:-
        Spams are unwanted Email message which are primarily send with the commercial commodities to recipient's.
Gmail has a spam folder to handle spam messages. Gmail transfer all spam messages into the spam folder . Spam folder displays on the left side of Gmail window.

            If spam folder does not on the left side of the Gmail window then you need to change account settings of Gmail account.
To change settings of Gmail,select option from the right side of the window and click on Labels tab.After this ,click on show in front of Spam.

What is Internet ??🤔🤔

It is a system with billions of user's worldwide. It permits communication and sharing of all types of information between any two or more computers connected through a large and complex network.
           
            It was started in 1960's and opened for public use in 1990's .With the passage of time it has witnessed tremendous growth and it is still expanding it's reach.its applications include;

1.E-mail:- It permits exchange of text/graphics material using e-mail software.we can write a letter and send it to the recipient through ISP's(internet service provider) who work like the dispatching and receiving post offices.

2.File Transfer:- A FTP(file transfer programmes)allows transfer of files/software from one computer to another connected to the internet.

3.world wide web:- Computer that store specific information for sharing with others provide website either directly or through web service providers.Government departments , companies,NGO's and individuals can post information about their activities for restricted or free use on there websites.
              This information becomes accessible to the user's.Several search engines like Google,Yahoo! etc.help us in finding information by listening the related websites.
       Hypertext is a powerful feature of the web that automatically links relevant information from one page on the web to another using HTML.

4.E-commerce:-use of internet to promote business using elecronic means such as using credit cards is called as E-COMMERCE . customer view images and receive all the information about various products or services of companies through their website.They can do online shopping from home /office .
    Goods are dispatched or services are provided by the company through mail/courier.

5.Chat:-Real time conversation among people with common interests through typed message is called as chat.Everyone belongs to chat group gets the message instantaneously and can respond repidly.

All about RAM & ROM in mobile phone.

RAM:-Random access memory.
....................................................................................
Basically computer memory refers to primary memory or main memory.Because this memory is directly in established in CPU.The primary memory is of two types i.e. ;1.volatile memory.
        2.Non-volatile memory.

The primary memory has different limitations,so secondary memory is established,which is also called as auxilary memory and is used for permanent purpose.
   RAM is a volatile memory.That means it accquires the data and information untill the power is ON.If the power is off then the data will be lost .

      The primary memory of computer is commonly refers to RAM ,because the computer can select the data rendomly. Generally this memory consist of some integrated circuit chips,either on mother board or attached to integrated board.


SIMMS:-Single inline memory modulus.
It means the extranal RAM which is plugged in to the socket for additional purpose ...

TYPES OF RAM:-
     1.STATIC RAM.
     2.DYNAMIC RAM.


....................................................................................
ROM:-Read only memory.
....................................................................................
Data stored in the ROM is permanent.i.e. if we want to store the data as permanent manner then we use ROM.
IT is also refers as internal memory.
e.g.,In our smart mobile the internal storage is nothing but the ROM chip set.
               The data stored in ROM chip by using the fuse link and the process is called as BORNING DATA.

Microprogram are stored in ROM chip, because it frequently used by computer ,PCs & mobile.

          There are many types of ROM in which even we earse the data by uv-radiation.

               TYPES OF ROM CHIP SET:-

            ROM:-

                  1.PROM.

                  2.EPROM.

                  3.EEPROM.

NOTICE:-

Keep your city clean.Then your mind will be refresh  all time and keep gaining knowledge everytime.

What is the technical Education ?.....📚📚

NEED IS THE MOTHER OF INVENTION.

As technology grows, so do the options for 

gathering and sharing information. Because while finding cat gifs or funny memes on the internet is fun, there are also scholarly dissertations on a variety of subjects, public domain novels and classics, and up-to-date scientific information.

This, in combination with advances in personal computing in both applications and general hardware, means that there are a host of new tools and methods that can be used to improve student learning outcomes. 

1. Teach With Open-Source Resources 

The open source movement is a technology in itself. The trend has already started with open-source education options available from high-profile universities and the Khan Academy. The trend should continue with our help. These open-source systems level the playing fields between the rich and the poor. When driven people are able to educate themselves, we all stand to benefit.

2. Tap Into Education Platforms Online 

With the rise of large online educational platforms such as Coursera, Udacity, Khan Academy and others, we see more and more people involved in learning from the best universities in the world. This trend is going to continue, with colleges starting to provide real degrees for finishing online courses (probably with in-person exams). Algorithms also help students learn faster and finish more often. 

3. Regulate Interactions 

We need to make sure that every kid has easy access to information, but I think one of the most important things is to use technology to regulate itself. Monitoring the when and why of technology can help parents make better decisions about how much, and to what end, children are interacting with simulations. 

4. Let The Kids Teach 

Kids instinctively know how to use technology that we once had to learn and assimilate. They teach themselves using that tech as they grow. Put that ability to work by letting them teach a classmate, parent or teacher using their preferred gadgets. Students can demonstrate they’ve assimilated new concepts and lessons by communicating them to others using the same tech they learn with. 

5. Switch To Tablet Learning 

More schools should switch to tablet learning and coursework submission at all levels. Kids and adults love using them, and are therefore more conducive to real learning, especially when adding gamification and virtual reality.

 6. Make Sure Higher Education Has High-End IT Options 

Higher education institutions face many challenges: financial constraints, small IT teams and increased competition. Remote monitoring and management, strong security postures and automating manual tasks are key enablers to higher education success. Commercial enterprise companies have access to affordable high-end IT innovations; our education system should have that access as well.

Life is a game play it well.. don't leave the game or don't copy it from other.

What do astronauts eat in space?

No one delivers pizza in space.It is sad but true.Eating in space presents some unique challenges for astronauts. Why? There's no gravity ! If you let go of a piece of food, it will float off and drift around your space vehicle.
       What about a cup of water? Forget it! Water won't stay in a cup. It, too, will float out and hang in the air.

To allow astronauts to stay in space for days or weeks at a time, scientists had to invent special ways of packagingand eating foods in space. The first such space foods were soft foods (kind of like baby food!) packaged in tubes like toothpaste.

For example, John Glenn became the first U.S. astronaut to eat in space when he ate applesauce from an aluminum tube during a 1962 Mercury space mission. He had to squeeze the food into his mouth.

If that doesn't sound very appetizing to you, you're not alone. Astronauts weren't crazy about it either. Eventually, scientists developed better, tastier foods that were easier to eat.

For example, freeze-drying was a technique that was developed. Food was cooked, quickly frozen, and then dehydrated in a special vacuumchamber. Freeze-dried food didn't need to be refrigerated and would last a long time.

To make most freeze-dried foods, astronauts squeeze water into the food packages and then eat the food after it absorbs the water. Astronauts can use hot water to make hot meals that are tasty and nutritious.

Some freeze-dried foods, like fruit, can be eaten dry. In fact, you may eat astronaut food from time to time without realizing it. Today, many breakfast cereals include freeze-dried fruits, like strawberries, that are delicious and add color and flavor.

Astronauts flying modern space shuttle missions now eat many of the same foods they eat on Earth. Food still needs to be dehydrated or prepared in special ways, but space shuttles now have full kitchens with hot water and an oven.

Astronauts can also use condiments, like ketchup, mustard, and mayonnaise, in packets to add flavor. Salt and pepper can be used, too, but they have to be used in a liquid form because otherwise the grains would just float away!

Drinks are also dehydrated and kept in powder form in special pouches. The pouches have built-in straws or special nozzles that let astronauts drink straight from the pouch since gravitymakes drinking from a cup a messy idea.

To make sure their food doesn't float off, astronauts attach their food containers and utensils to special trays with Velcro fasteners. The trays also fasten to their laps, so they can enjoy a meal while sitting down.

Nutritionists plan astronaut meals to make sure they get all of the nutrients and vitamins they need to perform their important work in space. Some astronauts begin to experience digestive problems after they've been in space a long time.

Experts believe these problems may be caused by a decrease in the number of “good" bacteria in astronauts' bodies. A group of high school students in Jefferson County, Kentucky, is going to help researchers learn more about this issue when the students' experiment flies into outer space on the space shuttle Endeavour.

As part of the Student Spaceflight Experiments Program, the students designed an experiment to test the effect of microgravity on Lactobacillus GG, which is a probiotic that could help future astronauts stay healthier in space.

In total, there are 16 experiments on Endeavour that were designed by students. This is only appropriate since Endeavour is the only space shuttle named by children. Elementary and secondary students competed in a national shuttle-naming competition in 1988.

The winning name — Endeavour — was based on an 18th-century British exploring vessel. The name has caused a bit of confusion at times, though. Many people want to spell it “Endeavor" since that's the American spelling of the word. The space shuttle, however, uses the British spelling with a “u" because that's how its namesake was spelled.

How Viruses effect our mobile ...📱📲📲📲

A virus is maliciously written code that replicates it self.It may damage hardware, software,or information files.Human interaction is necessary for a virus to spread to another user's files.New viruses are discovered almost daily.
             Most viruses exist simply to replicate themselves.Other can do serious damage ,such as erasing files or a document attaching itself to that medium.
TO AVOID THE ATTACK OF VIRUS:-
....................................................................................

1.Downloading apps from untrusted sources:-

Downloading apps from wrong resources is a great way to inadvertently end up infecting your smartphone with malware. Many hackers target users by getting them to download apps that look innocuous, but actually use repackaged icons of popular, trusted apps to trick people into installing software that attacks the device after installation.

So where should you avoid downloading apps in order to minimize the risk of inadvertently installing malware on your device? Avoid third-party app stores, which are numerous on the Android operating system and are notorious for hosting many apps that compromise Android smartphones’ security. Google’s vetting of apps submitted to the Google Play Store isn’t perfect, but it provides an important level of protection — protection you aren’t getting if you use a different app store. Many of the apps that you can download for a third-party app store collect information about your device and serve ad banners regardless of what you’re doing on your device.

2. Downloading the wrong apps from the Google Play Store or the iOS App Store:-

The only sure way to never download any malware is to avoid downloading apps altogether, since infected apps occasionally make it into the Play Store or the App Store despite Google and Apple’s best efforts to weed them out. So even when you’re downloading apps from the official app store, it’s still a good idea to do some research and use common sense to protect the security of your device.

When you find a new app that you’d like to try out, make sure to read some reviews first. They’ll usually tell you if there’s a problem with the app, and a complete lack of reviews is a big red flag that should tell you to avoid downloading until some appear. You can also check up on what the developer has created in the past and what kind of reputation those apps have. If the developer hasn’t published anything else, it may be a good idea to find an alternative.

3. Clicking download links on suspicious websites or in-app ads:-

Another avenue through which hackers promote malware-infected apps are download links placed on the web and as ads in other apps. Even if you aren’t using a third-party app store, you could still see malicious apps advertised when you’re browsing the mobile web. Even if a download link shows a name and an icon that you trust, you still shouldn’t tap a download link on the web or in an ad, even if you trust the website or the app where the link shows up. The upshot is that you shouldn’t download apps from locations other than the official app store for your phone.

4. Ignoring basic security practices:-

We wouldn’t advocate for spending all of your time and energy worrying about the security of your device. But if you’re going to be browsing the web and downloading apps on your phone, it’s not a bad idea to download an app that protects the security of your device. As Lookout notes, “sneaky, drive-by download sites can download a potentially malicious app file without any user intervention.” A good way to protect yourself is to avoid installing random downloads from your download manager, but security apps are a good way to block threats. Installing an app that will have an eye on the security of your device can free you up to worry about other things.

If you install an app that has the ability to run malware scans, complete one regularly. Depending on the app, you can run a scan automatically (whether you want to set it to once a day or once a week), which will help you keep an eye on the security of your smartphone. Take advantage of Google’s built-in malware scanner, and always keep your software up to date to ensure that you have the latest security fixes.

FROM THIS WAY WE PROTECT OUR MOBILE..

History of mobile phones

Martin cooper of Motorola made the first publicized handheld mobile phone call on a prototype DynaTAC model on 4 April 1973. This is a reenactment in 2007.

                      A handheld mobile radio telephone service was envisioned in the early stages of radio engineering. In 1917, finnish inventor Eric Tigerstedt  filed a patent for a "pocket-size folding telephone with a very thin carbon microphone". Early predecessors of cellular phones included analog radiocommunications from ships and trains. The race to create truly portable telephone devices began after World War II, with developments taking place in many countries. The advances in mobile telephony have been traced in successive "generations", starting with the early zeroth-generation (0G) services, such as Bell system's mobileTelephone service and its successor, the Improved mobile Telephone system. These 0G systems were not cellure,   supported few simultaneous calls, and were very expensive.

The MOTOROLA DYNA-TAC 8000X. First commercially available handheld cellular mobile phone, 1984.

The first handheld cellular mobile phone was demonstrated by John F.Mitchell and Martin cooper of Motorola in 1973, using a handset weighing 2 kilograms (4.4 lb).
                   The first commercial automated cellular network was launched in Japan by Nippon Telegraph and Telephone in 1979. This was followed in 1981 by the simultaneous launch of the Nordic Mobile Telephone (NMT) system in Denmark, Finland, Norway, and Sweden.Several other countries then followed in the early to mid-1980s. These first-generation (1G) systems could support far more simultaneous calls but still used analog cellulartechnology. In 1983, the Dyna TAC 8000X was the first commercially available handheld mobile phone.

In 1991, the second-generation (2G) digital cellulartechnology was launched in Finland by Radiolinja on the GSMGstandard. This sparked competition in the sector as the new operators challenged the incumbent 1G network operators.

Ten years later, in 2001, the third generation (3G) was launched in Japan by NTT DoCoMo on the WCDMA standard.This was followed by 3.5G, 3G+ or turbo 3G enhancements based on the high-speed packet access(HSPA) family, allowing UMTS networking to have higher data transfer speeds and capacity.

By 2009, it had become clear that, at some point, 3G networks would be overwhelmed by the growth of bandwidth-intensive applications, such as streaming media .
                     Consequently, the industry began looking to data-optimized fourth-generation technologies, with the promise of speed improvements up to ten-fold over existing 3G technologies. The first two commercially available technologies billed as 4G were the Wimax standard, offered in North America by Sprint, and the LTE standard, first offered in Scandinavia by Teliasonera.
