The first electronic {--mlinkarticle=6724--}computers{--mlinkarticle--} were created in the mid-twentieth century, between 1940 and 1945. Originally, computers the size of a large room consumed the same amount of energy as many modern personal computers (PCs) hundreds of machines working together . Today's computers are built with integrated circuits (ICs), which have a capacity millions and billions of times greater than in the past because technology has advanced significantly. People were not very popular back then. Computers are thus designed to have sufficient capacity per computer; if the capacity of the machine is insufficient, we should increase the capacity or store data in other ways, such as a {--mlinkarticle=5276--}flash drive{--mlinkarticle--}. We use computers and electronic tools more and more these days. We should understand the computer's {--mlinkarticle=2047--}unit{--mlinkarticle--} and the program's benefits and what the measurements are.

How to calculate units using a unit converter.
In the unit conversion program, it consists of username, number of units and units. - Username is to enter your name or enter the name of the person you want to calculate. - Number of Units Enter the number of units you have chosen, e.g. 10 units. - In the unit section, put the unit that we want to be another unit, such as Kilobyte , Megabyte , GigaByte , TeraByte , etc.
After entering the unit data that we want to convert is done, press to calculate and don't forget to click "I'm not a computer program" to prove that we are not a computer program. Then you can calculate.
After pressing calculate successfully, it will show us the result for example we want to calculate 10 MB. The result will be displayed in other units equal to 10 MB.
In the section of recent access information , we can click to see the latest information of the person who converted the unit by pressing show results. The results of all users who came to the unit will be displayed.
For example ,

Advantages of a unit converter
We don't waste time in calculating unit conversion because if we calculate by ourselves, the procedure will be very complicated because we need to find units to divide and raise power.
Make unit conversion values stable and accurate because if we convert the units ourselves, we may be wrong.
We don't have to pay for the cost of the calculation.
The quick unit conversion makes us more convenient.
It does not allow us to calculate the unit multiple times because the unit we select to convert the result of this unit converter program will appear alongside all other units.
This Convert Unit program can let us know Using the most recent user data, we determined which units and days to calculate.
This enables us to determine who has used this program and whether the number of units and units are the same. We are not going to waste time recalculating.
For this Unit Converter is called {--mlinkarticle=7502--}Program Convert Unit{--mlinkarticle--}. For anyone who is studying {--mlinkarticle=1--}Science {--mlinkarticle--}or just finished Science , you can probably tell that this string is related to numbers. There's a lot of and there are so many different formulas it makes calculating unit conversions a huge headache. This program is a program that has been developed for you to be able to use in various tasks and reduce the time of work more. In addition, this program also facilitates users who want to convert units quickly. The program can also convert to other units in one conversion cycle. The principle of use is not difficult because there are few steps to work by entering the username, number of units and the units you want to convert.

Unit conversion is the process of converting units from one base to another, such as converting from GB to TB. The base number system is related to {--mlinkarticle=3584--}computer{--mlinkarticle--} and is used to aid in the manipulation of digital or {--mlinkarticle=3052--}electronic{--mlinkarticle--} systems in computers or to represent unit codes of information in BCD, EBCDIC, and ASCII systems. Most of the number systems used in computers are binary. The octal number system and the hexadecimal number system must also be used to calculate the result. {--mlinkarticle=3999--}Mathematical{--mlinkarticle--} operators until changing the base number system in order to allow humans to understand each system unit of a computer

Computer and device capacity Each device has a different capacity, and how much we use it depends on how much we use it. A capacity such as a mobile phone's Micro-SD Card, a camera's SD- Card, or even a hard disk or SSD (SSD: Solid State Drive), as we see and are familiar with today, has a total of MB, GB, and TB. Examples of computer units that we are familiar with are 3MB image files, 128GB SSD capacity, 1TB HDD capacity, etc. With modern technology, we can create more storage capacity. As the size of the device gets smaller as it is a binary system, memory is often counted multiplied by 2. For example 8GB x 2 = 16GB and 16GB x 2 = 32GB will keep multiplying like this. Most of us see the capacity of hard disk or SSD will see it as 128GB, 256GB, 512GB or 1 TB etc.
What is the binary number system? The Binary Number System, or Binary Number System, consists of only 0 and 1, with Bi meaning two. The binary system was first coined by Gottfried Leibniz in the 17th century, around 1601 Christian era (2144 B.E.) to 1700 Christian era (2243 B.E.). This binary number system is something that is invisible to the naked eye, but is a system that exists in various parts of the device such as processing system, storage memory, etc. The binary system is the source of the "bits" (Bit) and "bytes" (Byte), where one 0 or 1 replaces the bit value of 1 bit. All 8 positions, or 8 bits, get 1 byte, and this leads to other numbering systems such as the ASCII system, and that causes the binary numbers to be translated into letters to store data in the computer's memory (Storage) because Binary has only 0 and 1 digits. As a result, both of these are symbols that only support two commands. The binary system is not restricted to computers. However, other IT equipment with a processing system Memory, such as mobile phones, calculators, theft signals, and so on, is also binary.
The basic computer storage capacity consists of KB (Kilobyte), kilobyte, MB (Megabyte), megabyte, GB (Gigabyte), gigabyte, and TB (Terabyte).
KB (Kilobyte) Kilobyte
Kilobyte (KB) is a computer unit used to count data larger than a byte (Byte), and is commonly found in documents such as Microsoft Word or PDF. The file will grow in size as the number of characters increases.
MB (Megabyte) is a unit that can be seen in everyday life and is a unit that people see often, such as a picture file, currently 1MB or more, audio or music files in a single .MP3 song will be 3MB or more in size. As for Video files, if the camera has a high resolution, it will have a larger file size depending on the length of each video file as well such as 1 song MV is about 3 minutes long, resolution at Full HD 1080p, file size will be around 300MB or more depending on the length of the video and the video quality. If the quality is low, we will have more space.
GB (Gigabyte) Gigabyte is a computer unit that is often seen together in the form of movie files. and installation files of various software or games and on storage media such as USB Flash Drive, SD-Card, SSD and HDD, etc.
Terabytes are storage capacity of SSDs and HDDs due to their large storage capacity, such as 1TB SSDs and 9TB HDDs.
How can we convert units?
We can easily convert computer units through the unit converter in this section, we just enter the data of the numbers that we want to convert and then select the starting unit to the ending unit. Unit conversion through the program will help us more convenient. If we calculate it ourselves, it can be confusing because the calculation is very complicated and also needs to be raised or calculated as the base of that number.
Examples of unit conversion that are converted from the program are as follows.
1 gigabyte equals to 1,048,576 kilobytes 2 gigabytes equals to 2,097,152 kilobytes 3 gigabytes equals to 3,145,728 kilobytes 4 gigabytes equals to 4,194,304 kilobytes 5 gigabytes equals to 5,242,880 kilobytes
Unit conversions allow us to better manage each area. We can make space for other parts as well. Unit conversion allows us to compare and know the difference between units. This article is written to provide a guideline for everyone to understand what each computer unit is, how they differ and how to convert a computer unit. I hope the readers will recognize and understand more computer units, which is important for measuring memory and storage capacity of many important {--mlinkarticle=6394--}files{--mlinkarticle--} and devices. We can convert computer units at Mindphp. This unit conversion program will be able to convert instantly just enter a {--mlinkarticle=54--}number{--mlinkarticle--} and then select the unit you want to convert, the program will calculate and show the result for us which the resulting table, Bytes, KB, MB, GB, and TB are displayed. Computer memory is currently expressed in kilobytes, megabytes, gigabytes, and terabytes, with each unit having a multiplier value. Different from 1024, but in general, when doing calculations, many people tend to estimate the multiplier value of 1000 to make it easier to calculate, but to get the correct number, we should use a program to convert the units.
