A computer is a tool that is used to process data or information. This computer is used daily for various needs, so the sense is very important to know.
The understanding computer was important. You must have been very familiar with computers in everyday life. Open internet, tasks, todo Office or open social media all need to understand how to use the computer.
Even if you open a program using mobile though, I guarantee you can operate a computer. Because mobile is one of the types of computers.
You may not understand it is understanding the computer itself, how it works, and computer components. But why this sense important?
For what you know what is the sense of a computer? Or what is the actual computer? This is important because you can open your deeper insights about the tools you use every day. How about later when you are asked by people, that computer, what the hell?
You want to be answered what? "That's why that create open social media, watch movies and also the task" that answer is not good quality!
So, let's discuss the understanding of computers, computer components, and all things related to computers. Let's go!
Understanding computers, components, and basic functions
A computer is an electronic device that is designed to process information. Computer word itself is derived from the Latin computer ' i.e. ', which means it is a count or a machine that can be programmed.
In other words, a computer is a tool that can process information. Now you've understood what it's computers and little understanding of computers.
The computer serves to accommodate a data or information, then that data is stored, processed in such a way, then the results are issued when required. All this process has the name commonly used in the computer world. Here is a brief explanation.
The input information is entered into a computer via input devices (a tool that places the data). Examples of input devices the most basic is the mouse and keyboard.
The microphone is also an input device. "why? mouse and keyboard are categorized as input devices? "
When you click the right or left, this means you give the command on the computer. The computer received orders as data. So including mouse and keyboard input devices.
Memory/Storage is storage in computers. To own a storage hard drives. While memory is performed on RAM (Random Access Memory).
Many people are confused about the differences between hard disk memory with RAM memory. Both are equally memory but what difference does it make? The point difference exists in the function. The difference is I will explain later on in the discussion about the hardware.
Processing is where all the information or data is processed. Doing this is the processor or Central Processing Unit shaped microchip.
The CPU has the toughest task since it is the brain of a processor. So, don't be surprised if your computer's processor is hot.
An output is where data or information displayed or presented in the data or the information is processed. A computer definitely comes with monitors as the output devices (a tool that unleashed the data/information).
If you have your speakers on your computer, the speakers also include output devices, as well as with the earphones.
Now you're more understand dong basics understanding computer? That's basically a computer is about input, memory/storage, processing, and output.
Daily computer functions
The function of the computer every day it seems easy enough to understand because it is essentially a great many benefits and you'll already know. An example is to create a document. This computer's understanding of its function in our daily lives.You may work, college or still in school. Surely at any given moment (or maybe every day) you need to create presentations, typing thesis, design a mind map, plan a schedule, or bookkeeping. You need a computer, because it is more practical than handwritten.
Well, some other examples such as; manipulate photos, download music video &, selling online and watch movies, video call, and many more. You can think of some other examples?
Some Types Of Computer
To know about the sense of a computer, you should also know what are the types of computers. When we hear the word computer, the first thing that comes to our mind is the personal computer as a Desktop or Laptop.However, the computer actually has many forms, usability, and size.
The computer performs many activities and functions are very close in our everyday life. For example, when making cash withdrawals from ATMs, scan the barcode at the supermarket, or using a calculator, we have been using a computer without us even knowing.
What the hell kind of computer is it? Some examples of existing computer and close in everyday life we are as follows:
Desktop computer (Personal Computer) is now almost in every building has a desktop computer. Home, Office, hospital, school, many using desktop computers to aid daily activities.
As the name suggests, the desktop computer is designed to be put on the table (desk: table, top: top). In general desktop computer made from several components namely, computer case, monitor, keyboard, and mouse. Chances are you also have, at least one.
Notebook. The form of the familiar text is computer notebooks. Or do we just call it with the notebook? The notebook is a portable computer or easily carried and transferred. Therefore, this type of computer is very loved by the people who are in school and work. Because of its versatility brought everywhere.
The notebook when compared to the desktop with the same prices, usually lower performance. If you want to buy a laptop specs performance equals & desktop, usually the price is more expensive than the desktop. This is because all the components on the notebook size should be smaller than your desktop so that the laptop easy to carry everywhere. In accordance with your needs anyway, if you travel a lot then the notebook computer that is right for you.
So the notebook is a type of computer that you can place it above.
Tablet or smartphones is a computer that can be gripped and more portable than a laptop. Tablet or smartphones don't use keyboard or mouse as an input device, tablets or smartphones using the touch-screen or buttons in lieu of a keyboard and mouse.
Although on the application, you can also add accessories such as a keyboard for your smartphone or tablet.
A server is a computer that serves information to computers that are in the network. For example, when we use the internet, we look for information that has been stored on a server.
The server computer is widely used by companies to keep the data confidential Office and to share data internally.
Wearables are a generic term for tools that can be used daily on the human body. An example is smartwatches and fitness tracker. Or maybe you are more familiar with the "Apple Watch"? Yes, this is a kind of small computers.
Game consoles are a computer specifically designed to play video games on your TV. Examples of game consoles are Xbox and PlayStation.
Smart TV, a lot of tvs are currently complemented by applications that can allow us to access online content. An example is we can do streaming video on the internet directly from TV, opening up social media, IP phones, and much more.
Computer Hardware
Computer hardware is the physical components of the computer system. On the device, there are computer circuit boards, integrated-circuit, as well as other electronic components. An example of a hardware device is a monitor that you are using at the moment to read this article.
The computer must have the hardware to operate existing systems. The hardware on a Personal Computer is generally divided into two sections, namely the internal hardware and external hardware. You must understand in order to deepen their understanding of your computer.
An example of an external hardware device is a monitor, keyboard, mouse, microphone, printers, projectors, scanners, speakers, and more.
An example of the internal hardware is processor (CPU), drive (Blu-Ray, DVD, CD-ROM, floppy drive, etc), the fan (heat-sink), modem, motherboard, RAM, sound card, etc.
To create a computer system, there are some basic hardware components that you must have. What are the basic components?
I will discuss the hardware components that are absolutely required to build a personal computer.
Many of us are very well versed in using personal computers, but not many know what hardware components are used.
With understanding or at least knowing about hardware components, you'll add your basic knowledge of computer technology.
A desktop computer should have at least 8 basic components. In it there is the case of the computer or the motherboard/tower, mainboard, Central Processing Unit (CPU), the Power Supply Unit (PSU), Random Access Memory (RAM), hard drive (HDD), Graphics Processing Unit (GPU) and several types of optical drives that will be CD/ DVD drive.
The 7th component this is the basic components required to create a computer system. To be able to use, don't forget to add the input and output devices such as keyboard, mouse, and monitor. The following discussion:
The computer case is a protective generally shaped box that will protect the wires and components from a computer in it.
Case computer works like a human body inside are important parts of a computer to work properly.
Using the case of the computer then the internal components of the computer will not be able to move freely or not deliberately.
A case which both also have a good air ventilation system so as to prevent excessive heat which can damage computer components.
The motherboard is often called a logic board, main board or "mobo", is the backbone of a computer. The motherboard has a function to connect all the components of the computer and make everything centered.
Hardware such as the central processing unit, hard drive, memory, graphics processing units, printers, ports will all be connected to the computer directly or through a specific cable that is connected to a motherboard.
So, dual-core CPU has two meaning, while quad-core means it has 4 CPUs. In General, the more the amount of CPU that we use on our computers, then that computer will be and the sooner the better in terms of performance.
Power supply Unit (PSU) is the heart of a desktop computer. The computer requires energy which is supplied by the power supply. Power supply gets energy from electric power AC (alternating current) in our home which was later converted into electric energy DC (direct current) which is needed to power a computer.
This component is often overlooked when assembling a computer. Assuming that the cheap PSU also able to give power to a computer. But as a human being, a healthy heart will make the body healthy. The worse the performance of a PSU then it will worsen the performance of the components of your computer.
It is not impossible that the cheap PSU can damage the components of your computer. By using the PSU is good and reliable, we can make computer components that we've got works according to the potential.
Hard drives or hard drive is also known as a place where all the information or data is stored. Word documents, music, movies, and all the photos that you have will be saved on the hard drives.
Hard drives themselves are permanent and not volatile, which means that if the computer is turned off, the data on the hard drives will not be erased.
In General, most hard drives used are a mechanical hard disk, which has a disk in it. To note on your hard drives is the size and speed of the round on the hard drives.
If you want to store a lot of data with large-sized, then we will need is the hard drives with a minimum size of 500 GB.
While the speed of rotation of the disk will affect how fast the hard drives be able to access data that has been saved. Generally, the speed round on the hard drives is 5400 RPM and 7200 RPM (RPM: radians per minute).
Solid State Disk is the hard drives with different hard disks. SSD can be represented as a pen drive with a larger size. If you have more funds, then you can consider buying SSD.
Because SSDS don't have a rotating disk in it, then any SSD performance claimed 50% faster than a hard disk.
Memory (RAM). RAM stands for Random Access Memory which is the place where the operating system, applications, and data that is being used is stored temporarily. So it can be quickly accessed by the CPU.
In this section, a lot of people are confused how to distinguish hard disk memory with memory in RAM. The difference in the two is actually very clear even though most people will not be able to explain it. In order not to include those of most people, I will give you know the difference.
If you place a larger RAM, your computer definitely guns will be ' slow '. Often hear that sentence? Why is that, anyway? RAM serves to help computers in storing data temporarily.
For example, in creating this article, I wrote an application in a word, before I save data to the hard disk, then this data will be stored in RAM or.
If the amount of RAM memory that we have the bigger, it will be also more and more able to hold data that is temporary.
RAM is also a very important role to make a computer can run multiple programs at the same time without having to make a computer becomes slow.
Memory in RAM is temporary, if you turn off the computer then the memory in RAM will be lost. Unlike the hard disk, memory is permanent.
Graphics Processing Unit/Video Cards. The GPU is an electronic circuit that serves to accelerate the creation of 2D or 3D images. Video cards were instrumental in generating a computer image of the beautiful visual on a computer monitor.
Of course, you have the monitor must also have the same good quality with the GPU you have. If the budget you have in making a computer is not much, then you can buy a motherboard GPU has had in it.
This is called the motherboard with onboard graphics. However, the performance generated by the Integrated GPU with the mobo is not as good as the GPU or onboard, generally called Video Cards.
To produce a visual image that is very good, the CPU will be burdened enough weight. Therefore, if we use a dedicated GPU, the weight of the job will be handled by the GPU. The CPU will do other work not related to the visual.
Optical Drives is a hardware device that uses laser light or electromagnetic waves to do the process of reading (reading) from the optical disc and writing (writing) data.
There are two types of drives, i.e. the drive can only read the disc and drive that can read and write. Compact Disc (CD), Digital Versatile Disc (DVD), and a Blue-Ray Disc is a type of optical disc that can be read or filled data by using the optical disc drive.
The monitor is a hardware device that displays video and visual graphics are generated by a computer with the help of the video card. Simply, the monitor is your screen. Yes, place all of the images, videos and other interface is displayed.
Monitors physically have in common with television but usually, monitors have a much higher resolution. And unlike television in General that can be affixed to the wall, the monitor is placed on the table.
The keyboard is a hardware device used to make the input text, characters, and other commands into the computer.
The keyboard is one of the most important parts of the computer. Without a keyboard is how we can send commands to the computer?
Mouse input devices are used by a computer user with a wave on the surface of the desk with the aim to direct a cursor on the screen of the monitor.
Other than that the mouse is also used to give commands by pressing a button on the mouse.
Already more familiar notions of the computer? What are the essential components required a computer? If your computer already senses better, let's go to the next stage of the "computer software".
Computer Software
Computer software is a set of instructions that can make users interact with computer hardware. As it has an indispensable hardware on a computer, as well as software.
A computer without the software will not be able to work. For example, without an internet browser, we can never surf in the virtual world using our computer. Without an operating system, internet browser will not be used.
Computer software is generally divided into two parts, namely, computer applications and system software.
Computer applications are programs that run a job for the user. System software including the operating system or the operating system and all utilities in it that makes a computer work.
There is an additional category in the software that is difficult to be classified, namely utility. A utility is a software system that aims to do an analysis, configuration, monitoring, or help a computer doing maintenance.
Utility, in General, is provided by the operating system or may be installed separately. Examples of utility are antivirus, backup software, clipboard, file manager, encryption tools, and others.
Computer Application
Computer application is a computer program that is designed to perform the desired tasks by computer users. Computer applications are also commonly referred to as application software or productivity program. Computer applications will use the capabilities of a computer directly to execute tasks ordered by the user.
Types of computer applications based on Function and needs
Computer applications created with in accordance with the needs of each. For example, office software, then inside there will be word processing, spreadsheet, database, presentation, and email.
Then if it will be used to surf in the virtual world, then its computer application is the browser IE, Chrome, Mozilla Firefox, and Internet Explorer.
Based on the tasks that can be performed by computer application then computer applications can be divided into several types such as the example in the following table.
Computer applications can also be differentiated based on how the computer application is distributed to consumers.
We often hear terms like freeware, free software, open source, shareware, trialware, and others. But too many people don't understand by these terms.
Of the distributed software as well as many types of software that functions as a negative adware and malware.
Freeware is free software if we want to use it. This software we can use it for free but we have to follow the regulations set by the manufacturer of the software.
In general, we should not change the freeware and not used for commercial interests.
Crippleware is software offered as freeware with minimal features or functionality. Crippleware is generally only allowing us to access features that are not the main feature of the software.
To use the main features of course with buying versions of commercial or shareware version.
Donationware is freeware that is distributed to users with notification or advisories to provide donations to freeware developers.
Free software is basically the same as the freeware that is equally a computer application that is distributed for free. The difference is in the rules that are created by the software developers.
Free software is free software that we can use, we can uninstall, change, learn, improve the performance of the software.
Other differences between the freeware and free software are free software will provide the source code to be modified. But to get the source code.
Similar to open source free software. Difference between open source can be tampered with, doctored and indeed be changed change it according to your needs. For people who like or need to modify the software.
Shareware is a software demo that was given away for free but in a certain time period. For example 15-30 day trial period. After users try the software, the software will not be accessible.
To access it we have to purchase a license for the software. Types of shareware like this can also be called with trialware.
Other types of shareware are shareware that has limited abilities or limited features. This type of shareware called liter.
Adware is short of advertising software. Adware is software that will automatically display advertisements on your computer. In general, the advertisements displayed by adware will shape a pop-up which is very annoying.
Bundleware is an unwanted software which will join the existing at the time of the installation of the main software. For example, if we want to install the software A, then on the installation wizard will be no option to install another piece of software in a single installation process.
Spyware is software that secretly will do the installation of other software on your computer. Spyware can contain code that will retrieve personal data on our computers which will be delivered at a time when we are connected to the internet.
Malware is short for malicious software. This software has a bad goal to exploit data on a computer without the user's knowledge.
If the malware is already installed on the hard drive of a computer, malware can take over the browser, perform tracking what websites you have visited, nor do any damage-damage to others.
Malware can hide and can even re-install though we have removed the malware on the computer. Viruses, Trojans, and other malware can be categorized as.
Scareware is malware created to trick users to users to download or purchase software that is useless even dangerous.
Scareware beguiling users bring up alarm or reminder to users by making users believe that their computers have been infected by malicious viruses.
If a user is tricked into downloading and installing the program, the program will be more deceiving users by displaying a fake warning that computer users have been infected with the virus.
The warning will instruct the user to purchase the full version software on the pretext that the full version will be able to eliminate the infection.
Finally, users buy full version software. This is the pinnacle of success from a scareware. Scaring users to buy the software.
Abandonware is when the development of a software has been discontinued by the developer and no longer support available.
In addition, to support, updates to software that was already owned by users also will no longer be available. New users who want to use the software also can no longer download or purchase the software.
Operating system
An operating system is system software that makes the hardware can communicate with the software.Without an operating system, a computer and the software will not work. Some of the famous operating systems are Microsoft Windows, MacOs, and Linux. Each is different in terms of user interface, but it is essentially the same purpose.
Well the tasks of the operating system which detects input from the keyboard, sending output to the monitor, remember where all the data is stored, and control all devices such as a printer, mouse, and others.
Well up here, you have a question about the sense of a computer? Please comment below.
Basically, it is not difficult to understand what it is and understanding the computer. You will certainly be more versed in understanding computer if you've never used a computer. Hopefully, this article was helpful for you, greetings!
