Let's learn about types of computer files. List of types of computer files A file is the named data space on the computer storage. The process of working with files is realized by means of operating systems.
A lot of operating systems lead to the existence of files and other similar processes: - data area optional on disk ; - devices - both physical and virtual; - data streams; - other objects of the operating system. Speaking of computer files in a general sense, we can distinguish the following types: 1. Program files are the executable files.
System files - these are files which you don't use but they must be on your computer for it to function well files inside a hidden Windows folder, registry files, and a few others are great example. Multimedia files.
These are your movies, music and other similar things. Archive fails - these files are compressed folders, back-ups, archives and more. Concept of computer files Computer files are the most basic unit of data that users can store on a disk.
This means that every picture on your computer, every card, song, video, movie, presentation are all files. Depending on the filing system, the files may have different set of properties.
Classes of computers
A file consists of records and logical units of a fixed size. It can have an arbitrary size depending on the record format. It is often assumed that a file is available at once in its entirety, in an arbitrary order from beginning to end. An array of information which is available only sequentially in this case is called a stream. Speaking of the operating system, the record is a byte and is the most common unit for measuring the volume of files.
This is the de-facto standard for the computer world. But other types of records are also used in specialized systems. For example, if the full filename is sweet home.
You see, it is not so difficult to understand the meaning and functions of a computer file. We use files every day and sometimes we do not even notice it.
Classification of computer files You cannot even imagine how many different types of files are on your computers. Except those that were named and those that you know. For organisational purposes, files are divided into random access files and files with sequential access.
Random access files are files that store information in a structured for searching and reversing form. In such files the search is carried out through addresses keys and ends with a provision of the desired file.
Modern analog computers usually employ electrical parameters, such as voltages, resistances or currents, to represent the quantities being manipulated. Such computers do not deal directly with the numbers.
They measure continuous physical magnitudes. Digital computers are those that operate with information , numerical or otherwise, represented in a digital form.
Classes of computers
Such computers process data into a digital value in 0s and 1s. They give the results with more accuracy and at a faster rate. Hybrid computers incorporate the measuring feature of an analog computer and counting feature of a digital computer.
For computational purposes, these computers use analog components and for storage, digital memories are used. According to functionality, Type of computers are classified as: A hybrid computer system setup offers a cost effective method of performing complex simulations.
On the basis of Size: For example, weather forecasting requires a supercomputer. Other uses of supercomputers include animated graphics, fluid dynamic calculations, nuclear energy research, and petroleum exploration. The chief difference between a supercomputer and a mainframe is that a supercomputer channels all its power into executing a few programs as fast as possible, whereas a mainframe uses its power to execute many programs concurrently. Mainframe Computer A very large and expensive computer capable of supporting hundreds, or even thousands, of users simultaneously.
In the hierarchy that starts with a simple microprocessor in watches, for example at the bottom and moves to supercomputers at the top, mainframes are just below supercomputers. In some ways, mainframes are more powerful than supercomputers because they support more simultaneous programs.
But supercomputers can execute a single program faster than a mainframe. In size and power, minicomputers lie between workstations and mainframes. In the past decade, the distinction between large minicomputers and small mainframes has blurred, however, as has the distinction between small minicomputers and workstations.
But in general, a minicomputer is a multiprocessing system capable of supporting from 4 to about users simultaneously. It is generally smaller in size than a desktop computer and larger than a notebook computer.
Palmtops have no keyboard but the screen serves both as an input and output device. Workstations A terminal or desktop computer in a network. In this context, workstation is just a generic term for a user's machine client machine in contrast to a "server" or "mainframe.

Time-sharing, to allow multiple users to interact concurrently on a single system. Embedded computers are chosen to meet the requirements of the specific application, and most are slower and cheaper than CPUs found in a personal computer. The term "microcomputer" has practically become an anachronism.
The best-known early system was the Altair , introduced in Nike shoe showing the transmitter that communicates with the iPod Source Smartshoes and smartclothes can also be used for competitive purposes, such helping athletes keep track of their running distance and speed.
Just like Chromebooks, they are primarily designed for web browsing, electronic communication, and cloud computing. In such files the search is carried out through addresses keys and ends with a provision of the desired file. These are of two types- Desktops and Portables.
Supercomputers[ edit ] A Supercomputer is focused on performing tasks involving intense numerical calculations such as weather forecasting, fluid dynamics, nuclear simulations, theoretical astrophysics, and complex scientific computations.
