- Hi guys! Hope you all are doing so great. Today, we're here because we're going to be displaying you aur informational video.
- Пързалка: 2
- This is our team, we are taking an associate´s degree in software development and analysis at Sena College.
- Mateo
- Jose
- Luis
- Пързалка: 3
- Actually through this informative video you'll learn different information and facts about Computer Science. Let's check it out!
- Пързалка: 4
- Now, maybe you've heard about a computer and its features.
- Пързалка: 5
- but have you ever wondered, how it really works?
- Пързалка: 6
- First of all, we need to know the concept of "¿What is a computer?"
- Пързалка: 7
- Actually, a Computer, is an electronic device that processes information or data, and executes commands
- Пързалка: 8
- Now that we know about what a computer is, we can continue into how it really works.
- Пързалка: 9
- Now we can divide the Computer into two main parts.
- Пързалка: 10
- The Hardware and Software Part of the computer.
- Пързалка: 11
- Now the hardware part.
- Is everything that can be touched. for example a laptop.
- Here we have the keyboard, speakers, touchpad, Screen, Camera, Mouse,
- Пързалка: 12
- Now for the software part.
- it is everything that can't be touched, for example.Applications like, Microsoft office or Visual Studio Code
- Пързалка: 13
- Also, ¿did you know the Software is the brain of the computer that tells the hardware what to do?
- Пързалка: 14
- Now lets continue with types of computers.
- Пързалка: 15
- There are many types like, desktops, laptops, servers, smarthpones, consoles, smart Tvs, and Supercomputers
- Пързалка: 16
- Now, we need many parts to make it work well.
- Пързалка: 17
- But there are 4 essential components that the computer needs, because without any of them, it wont work
- Пързалка: 18
- We start with the Input Devices (Keyboard, mouse, monitor, speakers
- Пързалка: 19
- Second one the CPU (Cental Processing Uniy)
- Пързалка: 20
- Third one the Storage (long-term data storage capacity)
- Пързалка: 21
- Four one, the OUTPUT (information that is displayed, printed, or transmitted to the user after the computer has processed the input data)
- Пързалка: 22
- And now my teammate Mateo, is going to continue with the information of the computers.
- Пързалка: 23
- In the world of computers, not everything happens inside the machine.
- Пързалка: 24
- There are also devices that help us connect and interact with it.
- Пързалка: 25
- These devices are known as peripherals.
- Пързалка: 26
- A peripheral is any device that connects to a computer to expand its capabilities.
- Пързалка: 27
- For example, a keyboard, a mouse, or even a printer.
- Пързалка: 28
- Without peripherals, using a computer would be almost impossible.
- Пързалка: 29
- Technology is everywhere, and we use it in many forms every day.
- Пързалка: 30
- But do you know which systems are used the most around the world?
- Пързалка: 31
- Let’s start with one of the most common: the personal computer.
- Пързалка: 32
- PCs and laptops allow us to work, study, and communicate efficiently.
- Пързалка: 33
- The second system is even smaller, but incredibly powerful.
- Пързалка: 34
- We’re talking about smartphones.
- Пързалка: 35
- These tiny devices fit in our pockets, yet they connect us to the entire world.
- Пързалка: 36
- Together, PCs and smartphones dominate modern technology.
- Пързалка: 37
- Inside every computer, there’s a part that acts like the brain of the system.
- Пързалка: 38
- This part is called the CPU, or Central Processing Unit.
- Пързалка: 39
- Its job is to process information and execute commands.
- Пързалка: 40
- At the heart of the CPU lies something even smaller — the microprocessor.
- Пързалка: 41
- Within this tiny chip, all the real thinking happens.
- Пързалка: 42
- The microprocessor performs four main functions.
- Пързалка: 43
- First, Fetch — it brings the instruction.
- Пързалка: 44
- Second, Decode — it interprets what that instruction means.
- Пързалка: 45
- Third, Execute — it performs the action.
- Пързалка: 46
- And finally, Store — it saves the result.
- Пързалка: 47
- Modern microprocessors are incredibly fast.
- Пързалка: 48
- Some reach speeds of more than 5 gigahertz.
- Пързалка: 49
- For example, the Intel Core Ultra 9 runs at 5.1 GHz.
- Пързалка: 50
- While the AMD Ryzen 9 can go up to 5.7 GHz.
- Пързалка: 51
- That’s millions of operations happening in just one second.
- Пързалка: 52
- Every computer needs a place to store and remember information.
- Пързалка: 53
- That’s where memory and storage come in.
- Пързалка: 54
- There are two main types of memory: RAM and ROM.
- Пързалка: 55
- RAM is a fast and temporary memory.
- Пързалка: 56
- It’s like a desk where you work — the bigger it is, the more you can do at once.
- Пързалка: 57
- ROM, on the other hand, contains permanent instructions.
- Пързалка: 58
- These instructions help the computer start and know what to do first.
- Пързалка: 59
- Together, memory and storage allow the computer to think, save, and retrieve information quickly.
- Пързалка: 60
- In simple terms, RAM is for “now,” and storage is for “later.”
- Пързалка: 61
- That’s the perfect teamwork inside every device.
- Пързалка: 62
- How do we tell a computer what to do?
- Пързалка: 63
- We do it through input devices.
- Пързалка: 64
- They are the bridge between the user and the machine.
- Пързалка: 65
- Examples include the keyboard, mouse, and joystick.
- Пързалка: 66
- We can also use devices like scanners or graphic tablets.
- Пързалка: 67
- And even microphones or special readers such as MICR and OCR.
- Пързалка: 68
- Each one sends information from us to the computer.
- Пързалка: 69
- Without them, interaction would simply not be possible.
- Пързалка: 70
- They make communication between humans and machines a reality.
- Пързалка: 71
- And now my teammate Luis is going to continue with the information of the Computer Science.
- Пързалка: 72
- Hi guys, and now i am going to talk about the unit storage of a file
- Пързалка: 73
- Now we have 5 types of unit storage mostly used.
- Пързалка: 74
- But the reality there are more than just 5, there are 8.
- Пързалка: 75
- I am going to start with the smallest to the highest unit
- Пързалка: 76
- First one is the Bit, the smallest that has around a storage of just 0 to 1 maximum
- Пързалка: 77
- First one is the Bit, the smallest that has around a storage of just 0 to 1 maximum
- Пързалка: 78
- The second is the Byte, that has around 8 bits of unit storage
- Пързалка: 79
- Third one is the Kilobyte that has around 1024 bytes
- Пързалка: 80
- The four is the Megabye, that has around 1024 kilobytes storage unit
- Пързалка: 81
- The five one is the Gigabyte, that has around 1024 Megabytes unit storage
- Пързалка: 82
- The six is the Terabyte that has 1024 Gigabytes unit storage
- Пързалка: 83
- The seven is the Petabyte that has 1024 Terabytes unit storage
- Пързалка: 84
- The eight is the Exabyte that has around 1024 Petabytes unit storage
- Пързалка: 85
- Now probably you're asking for why is that needed to know
- Пързалка: 86
- These units are based on the binary system and measure the amount of data that can be stored.
- Пързалка: 87
- And now i am going to give you some tips that you need to know to learn about computers
- Пързалка: 88
- First you need start with the fundamentals of a computer
- Пързалка: 89
- probably you're thinking what is that.
- Пързалка: 90
- is steps that you need do to and be learning with the time to be able to even create a computer or know about it
- Пързалка: 91
- for example the start
- Пързалка: 92
- u need learn about a hardware and a software
- Пързалка: 93
- u need to know how they work and each function
- Пързалка: 94
- u need to know how they work and each function
- Пързалка: 95
- And now to finish
- Пързалка: 96
- i wanna ask you something.
- Пързалка: 97
- .How do you feel after learning about computers?, now what do you know about them?
- Пързалка: 98
- Now in conclusion

- Пързалка: 99
- A computer is a powerful electronic device that works through the interaction between hardware and software. The CPU acts as the brain, processing data and executing commands, while memory and storage keep information temporarily or permanently. Input and output devices allow communication between the user and the machine, transforming data into meaningful results. Altogether, these elements make the computer an essential tool for work, study, and everyday life in the digital age.
