What is file size?
On the computer is the size of the file amount that occupies on the hard drive. The most basic unit of the file size, byte, is a string of eight binary digits or bits in binary code. The size of the file generally depends on the type of file; Text documents are generally smaller than graphically demanding documents or applications. Large files indicate more information stored in binary; The computer can also use decimal or base 10, such as people use; or hexadecimal, base 16.
Information on the computer, at its most basic level, is represented by electric pulses that move along the perimeter at the set voltage. Different sequences of these pulses are different types of information. Computers confirm only two state of the circuit fees: he, represented by 1; or off, represented by 0. In binary code, each digit, 0 or 1, is known as a little and eight of these bits form a byte, the most basic unit size of the file.s storage; For example, a text documentEnt in the notebook could be kilobytes or thousands of bytes. The installation program could be millions of bytes or megabytes. Although Kilobyte is usually considered equal to 1,000 bytes and Megabyte is equal to 1,000 kilobytes, in fact it is not. Because computers use Base 2, all measurements must be the power of two; The actual conversion factor is therefore 1 024.
Computer hard drives store these bytes as a series of magnetic fingerprints on the disk surface, and the disk head reads them to transmit information to the processor and output devices similar to how the laser reads the optical disk unit and transmits data. Hard drives contain a set number of sectors, each of which has clusters, which in turn contain magnetically charged parts of the disk. The size of the file is the amount of physical space taken on a hard disk; Systems set are organizational methods formatted on the unit to make urFor how the hard disk stores and approaches its data.
File size determines how much hard disk space is reserved by the file. Even after the file is removed, its information remains on the unit and can be restored. Deleting the file delets only the aspect "read only" that prevents the unit from writing via the file.
Two main classes of file systems are used: File assignment table and new technological file (NTFS). FAT stores data in the set size clusters and packs the data in the next cluster. These systems are useful for smaller units because the maximum size of the section is 4 gigabytes. NTFS is standard for each Windows NT operating system. It is used for larger units.
