[00:01:53]We have made all the facilities available for you.

[00:01:55]So you will get the link of all these in the description box.

[00:02:00]So let us come to our question series.

[00:02:02]So look, this is set 10.

[00:02:04]Whatever else has already happened, you guys can take a look at it. The question is which of the following system malware symptoms indicate that your computer may be infected? So here I am saying that which Marvel symptom indicates that your computer has been infected or may be infected. So look here, your slow computer performance is given in the option.

[00:02:25]Now see, if any system gets infected with malware, then obviously the performance of your computer will become slow.

[00:02:34]So this is it. Apart from this, see, he is saying that erratic behavior, computer behavior, means that your computer will behave erratically in a way. Meaning it will not work properly, it will run slow or other applications will open again and again.

[00:02:47]So these are also the symptoms of your malware effect. Apart from this, it is given that unclean data loss. So, when there is an effect of malware, then there is a possibility of loss of your data. Whereas you will not know how it happened and due to what reason it happened.

[00:03:06]Apart from this, it is said that frequent computer crashes, meaning your computer will keep crashing frequently.

[00:03:12]So all these are symptoms, meaning if your computer gets infected by malware, then look at it this way, here 1 2 3 4, all of them are correct. Meaning that these symptoms indicate that your computer has been infected. So in this way option one will be the right answer here. Rest, if we talk here that if your system gets infected by malware, then what are its indications? What could the effects be? So all this is given by you. Like the monitor can do that. What are you doing? It can slow down your computer's performance.

[00:03:47]Can download illegal files.

[00:03:49]Apart from this, all the data you have on the local disk can be destroyed. The IP address will be generated randomly and will be sent automatically.

[00:03:58]Apart from this, confidential information can also be stolen. Apart from this, your memory size can increase or decrease. Along with this, you can see that it can alter the settings of the PC.

[00:04:09]Apart from this, there are many other ways like your music coming or noise coming or beep sound coming. So all this shows that your computer has been infected with malware. And especially malware happens in many ways. As if you have got a virus, you have got worms. So all these are the effects of this.

[00:04:32]So you will get all this complete data here. See next question What does the PCB stand for? So see the full form of PCB has been asked.

[00:04:41]So, if we talk about printed circuit board in the case of computer language, then see, the correct answer for this will be PCB here. And look at the rest, all the important full forms of yours which are related to computer, we have created data of all of them here.

[00:04:57]So you guys should remember all these or you will find them completely inside the PDF, like see, all the full forms related to internet are there here like HTML, Text Markup Language, http, Text Transfer Protocol, so in this way many are given here.

[00:05:15]Like these are all full forms related to software.

[00:05:18]Apart from this, see here what is the full form of the top brands? Like you must have heard about Google, Yahoo, all these things, so all these also have full forms. So everything is given here. So you all should remember all this once.

[00:05:34]If someone asks a question on any of these, then you can easily answer it. So, all the important full forms are given in PDF. So you guys should prepare yourself from these and you will see only these in the examination. Next look at the question asked: How can a user define the cell address in an MS Excel sheet? So see, here I am asking that how can any user define the cell address and that too inside the MS Excel sheet. So see, if anyone of yours works in MS Excel, then the cell in it means basically the cell, your row column, all these are made in this manner, so see in this, if there is any cell specifically, then it has an address, so how is the address defined, this thing has been asked in it, so see in this, like your cell is made up of row column, this is its address, so see in this, the column which is there, we write it with letters and plus the row, it is done with numbers. Here you can understand with an example that if you want to define any of your cell address cells, then your column will be with your letter and the row will be with number, like your example is A1 or B5 or C. So see, by doing A B C, all these columns are yours. So this is done with alphabets and see the rest, like this is your row 1 2 3 4, this row numbering is done, so this is done with letters, so now here if we did A1, then A1 means which cell will come in it, so this one becomes A column and row becomes one, so this is the cell, in the same way suppose if we did B5, then B5 means B column and this one is five, so this means this one becomes your cell, so in this way the numbering is done here, this means the address of the cell is defined, so this [nasal sound] thing is important, you people should keep in mind that here this alphabetical alphabetic and numeric format is done so that we can identify the location of the cell and this is important, like it is done in many ways inside a cell when a formula has to be done with them or a cell has to be added. If we need to multiply them with other cells, then all this is done through the cell address only.

[00:08:03]So this is very important.

[00:08:05]So keep this in mind that the column will be by letter and the row will be by number. So here one will be the right answer. Rest you will see in the option that it is given that column letter plus row letter, so both the letters are not the column number, see the number is of the row. Not of the column. Column number plus row number. So look here, both the numbers will not be there. So in this way the one with one will be right.

[00:08:29]Rest, see the details like other questions asked from MS Excel, all of them are given in the PDF and we have explained it well in the lectures also regarding your MS Excel, how it works, its important things and other things that are there in it, that is, what options are there in it, how can questions be asked, so we have explained all this well in the course, so you people can go there and prepare for it well.

[00:08:57]See next: If You Need to Attach a Large File That Exceeds the Email Provider's Limit, What Is a Common Solution? Now look at this, it is being said here that if you have to attach a large file, which gets accessed through the memory provided by the email, then what is the common solution for it, which should be there here. So now see, you must have noticed this thing that if you have used email then your email provider like Google gives you a limit of storage but suppose you have to attach a file in it which exceeds its limit then what can be the session for that, so see all this, it will depend on what options are given, see here it is given that reduce the file resolution, now see this is not a session that you reduce the resolution of the file, then this will not happen. Next, see Break the File into Smaller Parts and Send Multiple Emails. So look, this is also not a common solution that you break the file into smaller parts and send multiple emails. So this will create confusion as to what you are sending to the users. Then look next at Use a cloud storage service and share the link. This means that you use the cloud storage service and share the link of whatever you have stored on the cloud storage.

[00:10:20]So, see, this is the most common solution nowadays. If you have a large file that accesses the email that provides you, then the best solution for that is to use cloud storage service and share this link in the email that you are sending. So this is the most common solution with respect to it. Rest, see, even after compressing the file into.g format, it is not a common solution by any means because nowadays, online cloud data storage is available, so you can save your large file in it and share its link, then any user anywhere will be able to access it. So all this is most important for you. So, regarding this, you have to understand it in detail as well, like what is email, regarding email, there are important topics, so you are asked all those questions, so you should know all this. For example, when we talk about email, it is a letter in a way. You send it to users just like in the olden times when you used to send letters, you used to write the address in it, to and from whom it was sent, all these things are present in it also. It is important here that if you are sending it to someone, then he should have his email address and you should also have it. So the email address has two main parts like one is your username and the other is your host name and both of these are separated by the @ symbol.

[00:11:42]So this is a very important thing because it is asked in the examination that what is separated from here? So it is done with the @ symbol and spaces are not allowed inside the email address. So all these common things which are facts, you have to remember them from the exam point of view. So, we have given all this in detail and explained it within the course. So you people can understand it from there regarding it.

[00:12:06]Apart from this, many questions are asked.

[00:12:08]Like BCC field What is CC field? So, you get questions from all these in your examination. Next is See here Given that Which of the following is the standard method to print a web page using the most modern web browser? Now here the question is what is the standard method here, like you have to print a web page and that too through which, if you have to print any web page through the most modern web browsers, then what is the standard method for that? So for that, look at this question, to understand its meaning, you will have to do it practically.

[00:12:46]For this, you just press Control + P or cmd + P. If you are using Mac OS operating system, then you have to press cmd + P, but if you are using Windows, then it is simple, press Control + P button. The rest of the web page will be printed as most of the web browsers support it. So in this way, your option one right answer here will be yours.

[00:13:13]Look, it is saying that it will not be printed by right clicking and selecting Save As. You won't get it even by pressing the F tool. If you press Control + S then this will also not be yours. This will save you. To print, press Control + P. So in this way, look at the one here, it will be the right answer.

[00:13:30]So in this way, you should also know all the shortcuts that exist. So you will find all these lists inside the PDF. From there you can do it well. Next, see, the question is given that whether the following device performs the signal conversion, so which device performs the signal conversion, so look here, a mouse is given, so look, it is a simple input device, when you click in it, it shows your cursor movement, that is, the print that comes in the monitor, so this is not a signal confusion device, next, see, your modulator is given here, so look, the modulator is given here, so basically, as you say modem, here, although it has both modulator and demodulator here, but the one which does the work of signal conversion, that modulator can also be yours, so look in this way, here B will be your right answer, it should have been a modem in it, although there is a modulator here as well, so this also does your work, like the work of converting analog to analog signal into digital, then digital to analog. So this signal conversion work is done by your modulator. Rest, just like the plotter is provided, your keyboard is also provided.

[00:14:47]So look at all these input devices, their work is not signal conversion.

[00:14:51]Rest, here you are asked questions about all the important networking devices. So you have to remember all that. Like the hub is your gateway, it is a switch.

[00:15:03]What is the purpose of all this? So you have to remember what you have. Which we have given in full detail regarding this and if any question is asked from them then you people can easily tell all this. As we call it hub, it also works like a repeater.

[00:15:18]Your gateway here is an interconnecting device that joins different network protocols.

[00:15:25]How does it work and what is its function? So you will understand all this well only after reading it in detail.

[00:15:31]Apart from this, there is another bridge here, what is its use? There is a router. What is its function?

[00:15:38]What is the function of a modem?

[00:15:40]You will get all this in complete detail.

[00:15:42]Next, look at the question which of the following represents the application used primarily for messaging and communication. So which one represents the primary application that we use it for? For messaging and for communication together. So, you must have seen the applications in your mobile or the laptops which are available these days for Windows, so there are many applications in it, but the primary ones that we use, for which I am talking here, for messaging and communication, so see what options are given in it, Gmail and Firefox, so look, we use your Gmail, we use it for emails, we use Firefox for browsing, so this is not for messaging communication, next, see, it is given WhatsApp and Telegram, so look, WhatsApp, so basically we send messages through it or we can also communicate, like it has voice chat and there is Telegram, so you get the same thing through it. So in this way, whatever is used for messaging communication, then your WhatsApp Telegram will become yours. However, you can see other options also, Safari and MS Word are given here, so look at Safari which is also your browser, MS Word, so this is your application based software, then look at Telegram and Safari, Telegram is there but Safari is not there, so here WhatsApp and Telegram will be the right answer. So, out of these, you might have used WhatsApp, Telegram, these are the top messaging platforms which people use nowadays. If we look at the number of other users, both WhatsApp and Telegram have a lot of users. So all these are common things which you can ask questions on the basis of your daily life as you remain connected online.

[00:17:32]Next, look at the question: Does Mozilla Firefox or Google Chrome or Microsoft require support for the Dash protocol? Now look, all these things like Mozilla Firefox, Google Chrome, all these are web browsers through which you can search the content. Meaning, if you put anything in it, it searches it and gives it to you. So look at all this, all the major web browsers like Firefox, Microsoft, they require support for http, https protocol and the modern security protocols like TLS 1.0 or higher, all these functions should be done well. So all these protocols are very important for secure communication. Like you have a browser, through which you browse and web server means the place where the content is stored, so to have secure communication with all of them, this protocol of yours is very important for you, http https, so if we look at all this here, like whom does it support, then it supports your HTTP 1.1, so you will have to remember this, its three will be the right answer, you will get questions in such a way also which you will have to remember. Rest, here we talk about browser, then see, browser helps you, through it you can search any content that is present on the internet and rest, see, there are many browsers like Netscape Navigator, your Internet Explorer, Firefox, Google Chrome which has been developed by Google here.

[00:19:14]Apart from this there is Safari, there is Opera. So all this is completely given by you. The list is given. So you guys remember all this.

[00:19:20]At least you should know what are the different types of web browsers? What is his name?

[00:19:25]Your questions are also asked from them. So all the major browsers that you have, all of them should support the protocol like HTTP and they do support it. So all these are important and remember all this for example, you people can ask your question from this and all the important things are given here.

[00:19:51]You will get to see only these. See all this, we have given it completely inside the PDF.

[00:19:55]Next, look at your question here: What is the primary function of a firewall tool in a computer network? So look, what are the primary functions of a firewall tool in a computer network? So if you look at it, like your Fireball, in a way it works like a bridge between the external network and this is your private network, like this is an external network and this is your private network. So now see, you have to secure the private network.

[00:20:24]So in this you have to create a firewall.

[00:20:27]Meaning, the main primary function of the firewall is that it monitors the incoming and outgoing network traffic, meaning which content should come in and which should not, it will monitor that, so look at this, your right answer will be to this, rest see, if it is said here that the speed of the internet is not used to increase the internet speed. It is not used to store data securely.

[00:20:53]To detect and remove viruses.

[00:20:55]See, this works as an antivirus for a virus, not a firewall. It monitors, basically, which incoming should come and which should go, so the firewall monitors all this. In a way, let us assume that it works like a bridge between these two and rest, see, regarding the firewall, what is its main thing, it is given completely regarding it, here your firewall can be in both software and hardware ways. Its main objective is to control the incoming and outgoing network traffic, in which it will analyze the data packet and determine whether it should be allowed or not. Meaning, here a predetermined rule is set as to who should be allowed inside and who should not. So only those who are allowed will be allowed inside. Whatever is left, it will block it here. So in a way, this fireball is very important for you and look at the rest, regarding all these, like all the important things related to computer security, questions are asked on all of them and whatever important things are there like what are the threats inside the computer when you use it online, then questions can be asked regarding all of them.

[00:22:08]So you will get its complete details in PDF. Next, look at the given question that whether of the following network devices connect to network, then which one of these is a network device that connects two networks, so look here it is given that bridge hub repeater or gateway, so now look at the two networks, they are different types of networks, like if it has to communicate with this network, then their protocol will be different, so look at them among themselves, like if it has to be connected, then a gateway is required for that, so look at this, the right answer will be yours, here which network device is used to connect two network devices, that is your gateway, so look at all this, you should know it first, only then you can do the question regarding it, otherwise, the functions regarding all these important network devices are given here, so you people can prepare yourself well with this, like your gateway is an internet connecting device which connects two different network protocols.

[00:23:09]It connects in the same way as if you ask about the hob or the switch, what are its functions, then you can see all this inside it, which we have given in the PDF and you will also have to understand it well, which we have explained well in the course, so if you see it once, you will not miss any question, even if you ask in any way, you will be able to solve it, I hope you must have got clarity on this thing here, so thank you friends, in the same way the sessions will continue in the future as well and see, if you want to buy a course, then you will get its link in the description box and we have given the link of all the PDFs in the description box, so you can buy it by going there.
