So, what are we dealing with? In fact, the complex hardware most familiar. In fact, many users refer to it as a computer "iron". Indeed, hardware - is instead the "iron" of software components of any computer system. In the simplest form of classification, they are divided into internal and external parts.

Also in this division are the three largest and most meaningful class of devices:

• An input device.

• An output device.

• Storage tool.

Naturally, it should be considered separately and thus a motherboard, CPU, and so on. E. As the basic elements of a computer system, included in any of the above classes and is a basic element, none of the computers simply will not work without which.

Basic Computer Elements.

Hardware should start with the most important element in any computer - on which all the internal components of the motherboard. And this is through the use of a variety of connectors and spans to connect external devices.

Today there are many different types of "motherboards" and their manufacturers. However, such cards may differ in the management of both forms and individual elements, for desktops and laptops. Nevertheless, the essence of their application in computer systems is not changed.

The second most important factor - the central processing unit, is responsible for efficiency. One of the main features is the clock frequency, expressed in mega- and gigahertz, or more, which determines just how much elementary operations per processor can produce. Obviously, the speed is nothing compared to the ratio of the number of operations in cycles that a unit operation needs to execute (calculate).

It is impossible to imagine computer hardware storage devices without RAM and hard drive strips. These will be discussed later.

Software And Hardware.

Such as ROM or unstable CMOS memory is the basis of basic input / output system, called BIOS which is used in modern computers and in hybrid devices.

It is produced not only on the "iron" chip, the motherboard. It has its own firmware which allows not only to store volatile data, but also internal components, and to test when peripherals have been computerized. Probably, many owners of stationary PCs when the auditory signal system dynamics relevant. This only shows that the device test is successful.

Data Input Causes.

Now let us consider the input devices. At the moment enough of these species, and can be judged by the development of IT-technology, soon they will be even more. Nonetheless, the following are considered to be the main ones in this list:

• keyboard.

• Mouse (trackpad laptop).

• A joystick

• A digital camera;

• Microphone

• An external scanner.

Each of these tools allows you to enter different types of information. .. Text, etc. However, there are also mouse, trackpad, and in addition to all of the controllers (manipulation) - a video image on a board - for example, created by a camera using a scanner.

For the keyboard, it controls the functions it uses via buttons or a combination of it. It is possible to get and access certain features, options and commands of operating systems or other software.

Information Production Reasons.

It is impossible to imagine without hardware production tools. The standard contains the following list.

• Monitoring.

• Printer.

• Author.

• Sound and video systems.

• Multimedia projector.

There is not a basic computer monitor or laptop screen. This is evident in the fact that in such cases the modern technique of object-oriented programming interacts with the user through the graphical user interface, although the system in which these input commands are assumed is equally applicable to the system. In any case, the user should see what is shown on the screen.

As far as other elements are concerned, they are not necessary (although, except that graphics cards, modern systems can not work, that is necessary).

Storage Media.

Finally, one of the most important classes and - storage devices. Their presence, whether internal or external media components, essential. These classes fall into the following categories:

• Hard Disk Drive (HDD).

• RAM

• Cache

• External drives (floppy disk, optical disk, USB device).

Sometimes CMOS RAM's BIOS system is included here, however, as mentioned above, instead of a hybrid device, can be attributed equally to different types.

Of course, the most important space and hard drives is occupied by "RAM". Hard Disk - This means hardware information (specifically, its storage) because it means it is stored permanently, and in RAM - temporarily (starting or operating program, content) Clipboard when copying, etc ..

Turn off your memory when the computer automatically clears, but the information is not going away from its hard drive. In principle, hard drives and such high-capacity USB devices now compete with removable media, but floppy and optical drives only go to the heart of their small capacity and the possibility of physical damage.

Communication Devices.

The optional class, although popular in the modern world, can be responsible for connecting phones and devices, (or even at the Internet release level) to individual computer terminals directly connected or liaising between networks. Cannot be isolated from key devices:

Network Adapter

Routers (modems, routers, and so on. DD).

As is clear, while providing access to the World Wide Web, not without them in the organization of networks (fixed or virtual). But few people today know that two computers, for example direct cable, could have been connected twenty years ago. Of course, it is somewhat feasible, however, not to be forgotten about any such possibility, especially when you need to copy large amounts of information, and a suitable career.Not in hand.

Safety Equipment And Data Protection.

Source
Now, another type of device. This includes hardware protection products, for example "iron" firewalls, also called firewalls (from the English firewall - "wall of fire").

Somehow today, most users are accustomed to the fact that firewalls (aka firewalls) are just software products. It's not like that. The use of such components is not something that is necessary when networking with a high level of security, and sometimes it is necessary. Part of the software does not always deal with their features because and not to mention access, can not respond in time to interfere with work from outside the network, coincidentally confidential information stored on computer hard drives or servers.

Software And Hardware Interaction.

Source
Thus, the hardware, we briefly reviewed. Now a few words software about how to communicate with them.

Coincidentally, operating systems that provide user access to your computer's computing capabilities have their own requirements. Modern "OSes" require so many resources, enough computing power that obsolete processors that do not tear up, or their absence will not get the required amount of RAM just work. This applies to random, even and modern software applications. And, of course, this is not the only example of cooperation.

In the end it is, however, equivalent to saying that part of the modern computer hardware was considered too short, to draw conclusions about what could be the basic elements of the rating system. Also, you should note that computer technology develops, but the fact that there are more different types of internal and external devices (carrying a virtual helmet) is also at the forefront. But as far as the basic configuration, the most important component in this case, without which the existence of any computer system today is impossible is not possible. However, here, for obvious reasons, we have a lot in common, although the device is slightly different from the computer terminal, because they have not been considered mobile devices.
