Experiment 0 , understanding and familiarity with operating system experiments

Major: Business Soft (2) class name: Log Hua Co No.: 201406114254

First, Experimental Purpose

(1) Master the definition and concept of the operating system;

(2) Understand the development history of various types of operating systems;

Second, experimental content and requirements

Use Web search to learn about various types of computer operating systems and organize them into a single document.

Test methods, procedures and results

Understanding and Mastering the content includes:

First, the definition and concept of computer operating system;

Operating system is an indispensable system software in modern computer systems, and is the foundation of all other system software and application software. The operating system controls and manages the hardware and software resources of the whole computer system, and provides a convenient, safe and reliable working environment for the user to use the computer.

The definition of operating system is generally considered as follows: Operating system is a kind of system software which manages hardware and software resources, control program execution, improves human-machine interface, reasonably organizes computer work flow and provides good running environment for users to use computer. The operating system has two important functions.

(1) Improve the efficiency of computer system through resource management.

(2) To improve the human-machine interface, to provide users with a friendly working environment.

The operating system is software, and is the system software. Its role in the computer system can be understood from two aspects: internal, operating System management computer system of various resources, expand the function of the hardware; external, the operating system provides a good human-machine interface, convenient for users to use the computer. It has a connecting position in the whole computer system.

Second, the classification of the operating system;

1. Batch processing operating system
2. Time-sharing operating system
3. Real-time Operating system
4. Embedded operating system
5. PC Operating System
6. Network operating system
7. Distributed operating system

Thirdly, the advantages and disadvantages of several common operating systems are analyzed; linux,windows

Linux is a free and open source Unix-like operating system. Can be installed in a variety of computer hardware devices. The fastest supercomputers in the world are running Linux systems.

Advantages:

1 safe, easy to maintain, stable.

2 software Free/open source, free.

3 Low cost-most.

4 Transparent public-the vast majority of gnu/linux are open to development.

Disadvantages:

1 missing apps and games you'll lose some of the familiar apps.

2 Lack of hardware support most hardware is supported, but not all.

3 It is often difficult to solve gnu/linux related problems and need to get help online.

Windows uses a graphical GUI, which is more user-friendly than the way the previous DOS requires typing instructions.

Advantages:

1 graphical interface is good, has a good integrated development environment, easy to operate. Provides a scalable, high-performance platform.

2 integration of common application software, simple, fast, convenient. Suitable for computer city sales personnel and maintenance of rapid installation.

Disadvantages:

1. System update backward, more loopholes, unstable, vulnerable to viruses and trojan attacks;

2. With low software version, you need to uninstall the upgrade yourself;

3. All software and procedures preinstalled in the C drive, aggravating the system burden, even if uninstalled, there are still a lot of debris files, easy to slow down the system.

Third, Experimental Summary

Through the collection and understanding of the operating system of various knowledge, can understand the various characteristics of the operating system,

The difficult problem of the experiment process and the method to solve it.

Through this experiment, we can get a better understanding of the operating system.
