Similarly, even if the computer is kept in a very hot place or in dirty places, the computer can give wrong results. Because the computer works well only in cool and clean places. • Diligence / Diligence / Continuity ( Diligence ) The computer never gets tired and the working efficiency of the computer is not affected by the number of hours the computer is working. If it works for 10 hours, then the work done by the computer in the first hour and the work done in the tenth hour will be exactly the same and there will be no difference in its accuracy. • Storage Capacity The computer has a lot of storage capacity in the form of memory to store data / information, computer stores the data / information in non volatile memory like ROM (primary memory) or hard disk drive – hdd (secondary memory) , Since mobile is also a form of computer but for data storage in mobile, ROM is used. Whereas HDD is used for data storage in computers like desktop / laptop etc. The HDD used in the third generation used to be of few MB but today even in normal computers it is in TB (terabyte). • Versatility The computer does not have any interest in doing any work and the computer is capable of doing all kinds of work. Where on the one hand we can play games, watch movies through computer, on the other hand we can launch rockets in space, leave satellites or treat a patient in the hospital through computer. • Automation The computer does all its work and the computer does not have to take any help from anyone in doing the work, in getting any work done from the computer, the user has to give instruction to the computer only once and according to that instruction The computer does all the work without any help, that’s why the computer is considered as an automatic machine. • Power of Remembering Whatever work the computer does, it can be stored in its secondary memory for future use and can retrieve that saved work when needed. There is a lot of storage capacity in the computer’s memory, so the computer can store and store a lot of data or information. • No IQ / No feeling The computer is less emotionless / feeling less, when we humans say something bad to another person, then he feels bad and does not do our work, whereas we keep calling the computer bad but the computer does not feel bad and that does our job properly.

what is email-benefits of email detailed information a 2 z what is email: The full form of E-mail is eloctronic mail, when we send a letter ie mail to any other computer or other device with the help of internet, then this process is called email. Today email is used officially to send and receive information in government departments and places like offices, schools, colleges etc. Email works in the same way as any ordinary mail works, just as we need the address of that person or organization to send a simple mail. In the same way, in email also, we should have the email address of the person or organization to whom we are emailing. Like while writing a simple letter, we write the name and address of the recipient above the envelop and the name of the sender below or behind the envelop and write our message on the paper inside, Similarly, to email someone, we need an email address which is made up of username and domain name. For example, mail@gmail.com is an email address in which the name before the @ is called the user name and the name after the @ is called the domain name. With the help of email, we can send our application, biodata, resume, images etc. or any other attachments to any specific individual or group of individuals through internet and we do not have to pay any fee for doing any email. In today’s time, many companies are providing the facility of email and they do not charge any fee for this facility. The names of some famous companies to these companies are as follows :- gmail, yahoomail, rediffmail etc. What can you do with email? Although Email was used to send text messages, but in today’s time we can send many types of files to anyone by attaching them to Email. For example, we can also send images, PDF, document, audio, video, program or any other file with email. Benefits of email ( what is email) Email has many advantages over ordinary email like Instant delivery When we send an email to someone, it gets delivered at the same time (within a certain time period) to the sent address because the delivery speed of emails is very fast. Instant reply When we get someone’s email, we can reply to that email at the same time whereas in normal mail it can take many hours or days to send a reply to someone. Stored communication Ordinary mails are written on paper which can be cut, torn or even burnt or lost somewhere. But Email keeps a record of all our conversations, which we can see anytime, print them and forward them to anyone. A copy of each email we send is stored on the email service provider’s mail server until we intentionally delete it. free communication The cost of emailing is negligible because in email we do not use ordinary mail like paper, pen, envelope or ticket etc. Our expenses are only incurred in using the internet because most of the email service providers also provide the facility of emailing for free. In email, we only need internet, computer or laptop or smartphone. An email account is also necessary for emailing and we also create this account for free, in this we do not have to spend a single penny. Secure communication Ordinary mails are often lost or accidentally sent to someone else But emails are very secure because wherever the email goes, only they can read this email. And to read this email, he opens his email account with a login id and password, no one can read that email without login id and password. Different types of file sharing In email, we can also share multimedia files and various types of document files and audio, video files, images. what is email Losses from email ( what is email) Emails have many advantages, but along with it there are also some disadvantages which are as follows. Internet connectivity We all depend on Internet connectivity to send or receive emails. And good internet connectivity is not available in many places, Due to which when we have to email, our computers / smartphones etc. are not able to connect to the internet and due to this it becomes sometimes difficult to do emails in such places. Spam / unsolicited email Many companies do email marketing to expand their business or to sell their goods/services. And in this email marketing, they email more and more people. In which there are also such people who do not want their goods / services and for them those emails are unwanted ie undesirable emails. When these are filled in our inbox in large numbers, it becomes difficult to find the emails we need, such emails are called spam. email files size limitation You can share files through email, but the size of the files should be of a certain limit, We cannot send large size files in Emails, there are some rules on Files size in Emails, such as Gmail cannot send large files larger than 25 Mb via email. email files types limitation Not all types of files can be sent in emails, only certain types of files can be sent through email. For example, files whose formats are doc, xls, pdf, txt, html or mp3 etc., then such files can be sent by email but exucatable formats like .exe files cannot be sent by email, To send .exe files, first those files have to be converted into .zip file and after that you can send them through e-mail. Technical Knowledge You should also have some technical knowledge to email. Like you should be able to run computer / smartphones etc and also you should be able to use the website / app of the email service provider you are using, You should know that after sending the email, it is visible in sent or not, whether it is not lying in the outbox,

what is internet a 2 z complete detailed information what is internet- This is the most searched topic of today’s students, many websites are explaining this topic in different ways, while it is very easy to understand. Before understanding the Internet, I want to tell you that in any word its meaning or definition is hidden. In the same way, its meaning is hidden in the word internet as well :- It is made up of 2 words inter and net. That is, the net connecting 2 or more than 2 or outside our net Like international, inter and national is made up of 2 words. i.e. connecting 2 or more countries or beyond our country What is Internet ? what type of network is the internet Let us understand this in simple language – When many computers are connected to each other, then the network made by their connectivity is called net. And when different nets or networks of computers spread all over the world are connected with each other, then the network made of this type of connectivity is called internet. There are many computers in this type of network which are called routers, these routers determine the best direction for the data / information sent by us to another computer. There are many computers in the internet which are called servers and these servers serve to give the information requested by any computer, that is why these computers are called servers. Countless computers spread around the world are connected to each other through Routers and Servers and exchange data / information with each other. Data / information exchange or transaction between different computers is done under certain rules, which you can call communication protocols and these rules are called TCP / IP. Every computer connected to the Internet has a different identity and all computers get this unique identity from the IP Address, IP address provides a separate identity to any device connected to the Internet. For example, if someone sends us a letter, he should have a specific physical location to identify our home or business office. In the same way, to give a different identity to different devices in a network, that is, they are given an IP address to differentiate. IP Address is a unique set (eg 104.196.180.202) and it tells the location of any device or computer connected to the internet. The IP address is linked to any one name by the Domain Name Server ie DNS and that name is called the domain name. Like https://scrubindia.com is a domain name and it has been linked to the IP address of the computer/server on which this website is hosted. What is the full form of TCP / IP? Transmission Control Protocol / Internet Protocol With the help of this TCP / IP, computers spread all over the world share data / information with each other in a network. In this way a network working with certain rules is called Internet. So in this way you can say that the Internet is a network of computers connected to each other spread across the world, that is, it is a global computer network which is designed to share many types of data / information among themselves. This data or information can be of any type like text, graphics, images, audio, video etc. And on the basis of similar data / information, today many social media platforms like facebook (meta) / whatsapp, twitter entertain us and are popular among billions of people. Internet was earlier also known as internetwork but we speak by shortening any word. Like in today’s time very few people speak internet and the word internet has become smaller and only net. In the same way the internetwork was shortened to become the internet. Who invented the Internet / Who made the Internet How did the Internet develop? The Internet has not been invented by any one person, just like the computer has not been invented by any one person, You will be surprised to know that the Internet was invented to win the war. Yes, in the 60s, there was a cold war going on in America and Russia. And the confidential information of both the countries used to be known to each other. To avoid this problem, America wanted to create such a network so that the confidential information of the US Army could not be leaked. And the US Defense Department first appointed Leonard Kleinrock for this, he was asked to create such a network. In which information can be exchanged securely and in less time by connecting multiple computers together After that with Leonard Kleinrock the scientist J.C.R. Licklider and Robert Taylor also joined These scientists created a system to send information from one computer to another, which was called “Packet Switching”. For the development of the Internet, America created the Advanced Research Projects Agency (ARPA) in the year 1957 and created a network called ARPANET. NCP (Network Control Protocol) was used to connect one computer to another in ARPANET. On October 29, 1969, ARPANET sent its first message by writing “LOGIN” and only the first two letters of this message could be sent “LO” and the network crashed as soon as g came. Because the network crashed between the 2 colleges connected to this network, this messaging was partially successful. In 1969, 4 computers in ARPANET used to communicate with each other by connecting to each other, but gradually this network started getting bigger. And in 1970, Harvard, MIT, and BBN (the company that used the computers with “interface message processor” used to build the network) were added to ARPANET. In the year 1971, the University of Hawaii’s network was added to ARPANET, which was named ALOHAnet and after a few days some more colleges / universities were added and in the same year Ray Tomlinson created the email After this, in the last years of the 70s, Vint Cerf and Robert E. Kahn jointly created the TCP /
