A subsystem of a system is computer software. What is a computer and how does it work

Plan - lesson summary in grade 6 on the topic: “ Personal Computer as a system"

Checking those present. Ready for the lesson.

Hello children! Sit down. We prepare notebooks, textbooks, diaries

Motivation. Today we will study an interesting topic on which you will learn a lot of new and interesting things.

DZ check. Let's start the lesson by checking the homework.

1. The first task is to identify subsystems in objects: a car, a school. We show notebooks with completed tasks. (I look at how someone did it and say:) Karina Kolobzarova come out with a notebook (we check on the document camera). Name the subsystems in the diagram. What is a supersystem? We check. Who can add?

   What types of systems do you know? (called systems). So, all systems can be divided into three large groups: intangible, material, mixed. In turn, material systems are divided into natural and technical. Determine what type of systems the pictures on this slide belong to. Who wants to board? (I call three people in turn). Name the first four systems. Fine. The next one will go .... also define four more systems. AND latest systems will determine .... Check your results. That's right. (not true, tell me where to move this picture? Justify your answer).

   Let's check the last crossword puzzle. Guys, as you can see on the slide, two concepts are hidden under the numbers 2 and 4. I would like to know the answers to them. The second task will read ... Will there be an answer to this question? Great! Now question 4 will read….What is the answer to this question? Excellent, well done! Guys raise your hands who correctly solved the whole crossword puzzle? All well done!

Setting goals and objectives.

We examined various systems, analyzed their structure, and named their components. In almost every computer science lesson, we work with one very important technical system. What is it called? Today in the lesson we will look at this system in detail. Who can name the topic of the lesson? (computer as a system). Write the date and topic of the lesson in your notebook. (Go see how they write).

Tasks. Remove unnecessary tasks and name the tasks of the lesson. (I circle with a marker).

Explanation. Let's look at the familiar computer object from a different point of view. It turns out that the computer can be considered as a supersystem and a subsystem.

PC as a subsystem. The personal computer includes the following subsystems: hardware, software, informational resources. Sketch this diagram in your notebook directly from the topic of the lesson. Consider the components of these subsystems. (I open the curtain.) Can you tell me what is included in PC hardware? Name the input devices. Information storage. What is included in the uprising information resources? The operating system includes ... .. (I tell you what it is). Thus, the PC in this system acts as what kind of system? Supersystems (I put forward).

Man is a computer. What systems do you see in this picture? Chel-computer. What is a supersystem in this system? Correctly in this situation, the computer is a subsystem.

Physical education minute. (I turn off the blank board). Look up with your eyes, blink, up to the right .... Take a pen, put it in front of you and look at the pen and the board, repeat seven times.

Job cards. Relax, now let's get to work. We divide into groups of two people, one desk will be one group. I distribute cards and which you should indicate with arrows the supersystems and subsystems of the computer. The time to complete the task is 1.5 minutes. Quietly confer, then consider the answers. Time has gone.

So, the time is up, name the subsystems of the computer. Roma. Roma called everything? Who wants to add? Name the supersystems of a computer. (Same procedure)

Interface.(I turn on the board). Pay attention to the board. The means that provide the relationship between the objects of the "Man - computer" system is called an interface. Distinguish:

Hardware- means of interaction between computer devices.

Software - means of interaction between programs.

Hardware software - means of interaction between hardware and software of a computer.

Custom - means of human-computer interaction

Practical work. Open page 40 of the textbook and find the subheading interface. Using this item, do practical work on computers - fill in the diagram. It is located on the desktop of your computer. (After 7 minutes I ask). Who did well and worked in the lesson I put marks.

We sit down at the desks. What new did you learn in the lesson? (children call).

The most important. The human-computer system includes subsystems .... And the means that provide the relationship between the objects of this system are called the interface.

Homework. Write down your homework: p. 6. Pg. 41, answer questions. Crossword.

Reflection. Guys, sit down at the computers and evaluate your work in the lesson. Leave the result on your desktop.

End. Thank you all, you are welcome.

One of the objects considered in computer science lessons is a personal computer. It can be considered as a system consisting of subsystems "hardware", "software", "information resources" (Fig. 20).

Rice. 20

Subsystem hardware acts as a super-system for devices for input, processing, storage and output of information.

Operating system - a software subsystem and a supersystem, which includes system and utility programs.

The information resource system includes systems of text and graphic files, sound files, files with video information, etc.

A personal computer is a part (subsystem) of the "man-computer" system.

User interface

The means that provide the relationship between the objects of the "man - computer" system is called an interface.

There are hardware, software, hardware-software and user interfaces.

Hardware interface- means of interaction between computer devices; provided by equipment manufacturers.

Software interface- means of interaction (compatibility) of programs with each other, as well as software and information resources; provided by software developers.

Hardware-software and user interfaces are provided operating system computer.

Hardware-software interface- means of interaction between hardware and software of the computer.

User interface - means of human-computer interaction.

The menu-based user interface offers the ability to select a control command from a menu (command list). In GUI computer objects represented by small drawings (icons). The desired icon is selected with the mouse. In addition to icons, texts (for hints) and menus (for selecting commands) are also used.

The 3D interface allows navigation in 3D computer space. By pointing the mouse, for example, at the door of a virtual museum, you can enter it. In the virtual hall, you can look around, approach any picture and examine it in more detail. This interface mimics the real world.

• One of the objects considered in computer science lessons is a personal computer. It can be viewed as a system consisting of subsystems:

• "Hardware",

• "software",

• "informational resources".

Hardware

The hardware subsystem acts as a supersystem for information input, processing, storage and output devices.

operating system

The operating system is a software subsystem and a supersystem, which includes system and service programs.

Information Resource System

The information resource system includes systems of text and graphic files, sound files, video information files, etc.

man - computer interface .

The personal computer is part of the system man - computer ". The means that provide the relationship between the objects of this system are called interface .

There are hardware, software, hardware-software and user interfaces.

• Hardware interface - interaction between computer devices; provided by the manufacturers of this equipment.

• Software interface - interaction (compatibility) of programs with each other, as well as software and information resources; provided by software developers.

• The hardware-software and user interface are provided by the operating system of the computer.

Hardware-software interface - the interaction of computer hardware and software.

The user interface is the interaction between a human and a computer. The menu-based user interface offers the ability to select a control command from a menu (command list). In the graphical interface, computer objects are represented by small pictures (icons). The desired icon is selected with the mouse. In addition to icons, texts (for hints) and menus (for selecting commands) are also used.

The 3D interface allows navigation in 3D computer space. By pointing the mouse at the door of the virtual museum, you can enter it. In the virtual hall, you can look around, approach any picture and examine it in more detail. This interface mimics the real world.
