[00:00:00]Hello all, welcome back to our channel.

[00:00:02]So, students in this video we will discuss the basic computer skills explanation as well as a quick revision so that you will have a clarity what you need to write in the exam everything, okay? So, as many of you have commented about the basic computer skills, so in this video you will have a clarity. In old videos I have already given the gun shot questions, you can follow that gun shot question to score O grade in this subject. Here in this video we will discuss a quick explanation video. So, let's get into the video, students. So, students, this is the syllabus pattern of you as I have already discussed unit one and unit two you are having. So, unit one introduction to computers and unit number two number system and computer codes. So, in this video I will explain the explanation videos of the questions so that it will be like a quick revision for your preparation of BCS, okay? So, whoever have written EBS in sem one, in sem two you will have BCS, ma. So, in that the first important is what is computer, okay? So, the term computer is defined as a 1 minute.

[00:01:18]Okay. The term computer is derived from the Latin word compute which means calculate. A computer is an electronic device machine from performing calculation and controlling operation. So, you need to remember this two lines as it is. A computer is derived from a Latin word compute which means calculate, okay? Why we will use this computer? It is an electronic device where it performs calculations and controls operations, it stores data.

[00:01:50]Like that you can write it, okay? So, a computer is the most influencing force available in modern terms due to its memory, high speed, and perfection, its application can be extended to most almost infinite levels.

[00:02:06]Okay, so this is the introduction.

[00:02:08]Definition of computer means computer is a device that transform data into meaningful information. Okay, it transform the data into meaningful information. Okay, so it stores the data, it accepts the data, it process the data, it retrieve the data. Retrieve is nothing but backup. Okay, it will print the results, everything. Okay, so the important I have said that characteristics of computer. In that the first characteristic is speed.

[00:02:42]Okay, compared to the human work, computer is little bit of speed. It works speed. Okay, so money sheet 24/7 work chain in, but whereas machinery, it will work 24 into seven. Storage capacity.

[00:02:57]Storage is also a great thing.

[00:03:00]So storage it will store the huge number of data compared to the manual storage, computer storage is little bit easy and it secures more data. Okay, and accuracy. Accuracy is current correctness. Okay, and compared to the accuracy will give more and more in the computer.

[00:03:20]Versatility. Versatility is the thing it will perform any task. Whatever the task you're giving the device, it will perform any task. Okay, number of times it will perform. Okay, and next one is automatic. Automatic is nothing but it can automatic. So there is no human value can be needed in that automatic automatic process. It will be doing. It will perform automatic functions, etc. And the sixth one is diligence.

[00:03:49]Diligence is nothing but loss concentration. Okay, it does not get tired, it does not have hungry, like that, no? So, like that, okay? So, this is the characteristics of computer. This is an important questions, ma. And generations of computer, it's a little bit easy, but no need of learning, okay? So, it's not that much required, okay? So, generations of computer, I'm skipping this question. If you want to learn, you can learn from the PDF. I have uploaded in Telegram group, okay? So, you can search in that, okay? Next, you are having block diagram of a computer. This diagram, whatever you are having, you need to be draw this diagram. You need to be perfect with this diagram, okay?

[00:04:34]So, in this diagram, you will have input unit and output unit, memory unit, control unit, and arithmetical logical unit, okay? So, as you have already learned FIT in semester one, same syllabus you are having for BCS also.

[00:04:48]Same answer, same syllabus, everything will be same, okay? So, that's why I have already explained the FIT video.

[00:04:56]You can watch that video, okay? So, it's like a click glimpse of the BCS video. So, that's why I'm not discussing in detail, okay? Even write all the exam key sufficient. How you need to return that examination, what are the things it will be sufficient, that's I'm saying in this video, okay? And input and output devices. Input devices is keyboard, mouse, light pen, optical scanner, touch screen, microphone, draw, trackball, like this. And we can all write it, okay? Minimum six inputs you can remember. And coming back to the output, you will have monitor, printer, okay?

[00:05:37]And [snorts] a plotter, speaker.

[00:05:40]So, these are all output device, okay?

[00:05:42]So, this is the important thing, ma. So, this will be easy, and this questions is enough from unit number one. Okay, so more questions if you want to learn this you can learn from this PDF. This PDF has both unit number one and unit number two. If you're perfect with the long, no need to learn the short. So we can cover it out of 40 marks question paper, you need to write minimum front and back four sides for long, okay? Front back, front back, four sides or two pages, okay? Compulsory it is there, okay? And uh next important is a Windows, ma. As I have already given the important questions, uh Windows features and applications of Windows is this is an important thing and firmware, middleware, what is the firmware? RAM, EEPROM, double EEPROM, okay? And the middleware, uh in that middleware you will have the network operating systems, LAN, MAN, WAN, okay?

[00:06:40]So this is a thing. Try to draw this type of flowcharts, my. It is easy and it will give attractive, more attractive to the paper evaluator, okay? So whatever you have remembered the points, you just convert that points into a uh like a flowchart. It will be easy, okay? Windows is easy from second unit and spreadsheet also I have given, no? So spreadsheet also easy and important the question from unit number two, okay? So this is the binaries, my.

[00:07:10]You can write it or you can skip it, no problem in that. And uh first thing is presentation your of your paper is important and the second thing is attempt every question whether you know or don't know the question, but you need to attempt the question, okay? So that is important. Okay, students, many of the students what they will do means uh I have I don't know the question, ma.

[00:07:33]The akka I have that's why I didn't attempt it. Don't do that uh silly uh reasons because whether you have attempted every question or not is important, okay? So, that's why I will tell each and everybody to attempt the questions, okay?

[00:07:48]Remaining will be remaining, okay? But, attempting the question is important, okay? So, this is all about the video, students. I hope that you have got clarity about this ABCA subject as many of you were requested for this video and it's time 5:35 a.m. So, try try to ignore my words because I'm having some cold.
