Question 3: What does computer software include? Include system software, application software

System software refers to the operating system, such as Windows xp and dos. Linux and other commonly used operating systems, but basically windowsXP or human win7.

Application software is a program developed for specific needs, such as office software: word, Excel, Powerpoint, Access, etc. There are many game softwares, and I won't list many learning softwares and communication softwares here.

Question 4: What does a computer software system include? Computer software is generally divided into two categories: system software and application software:

System software is various operating systems, such as windows, Linux, UNIX, etc. , including operating system patches and hardware drivers, are system software.

There are more kinds of application software that can be subdivided, such as tool software, game software and management software.

system software

The system software is responsible for managing all kinds of independent hardware in the computer system and making them work in harmony. System software enables computer users and other software to regard the computer as a whole, regardless of how each underlying hardware works.

Generally speaking, system software includes operating system and a series of basic tools (such as compiler, database management, memory formatting, file system management, user authentication, driver management, network connection and other tools).

application software

Application software is software developed for a specific purpose. It can be a specific program, such as an image browser. It can also be a group of programs with closely related functions that can cooperate with each other, such as Microsoft Office software. It can also be a huge software system composed of many independent programs, such as a database management system.

Question 5: What does computer software generally include? Computer software refers to programs, data and files in a computer system. Program [1] is the description of the processing object and processing rules of the computing task; Documentation is to facilitate the understanding of the explanatory information required by the program. Programs must be loaded into the machine to work, and documents are generally for people to see, not necessarily loaded into the machine.

Software is the interface between users and hardware. Users communicate with computers mainly through software. Software is an important foundation of computer system design. In order to facilitate users and make the computer system have higher overall utility, the combination of software and hardware, as well as the requirements of users and software, must be considered comprehensively when designing a computer system. -Excerpted from Baidu Encyclopedia.

Simply put, the QQ, browser, operating system, input method and music listening tools you are using now belong to the category of software.

Question 6: What does complete computer software mean?

Complete computer software refers to programs, data and corresponding documents, because software is defined as computer programs, processes and rules related to the operation of computer systems, as well as possible files, documents and data or related data and documents for development, use and maintenance.

Question 7: There are many kinds of computer programs, including those! Executable program. Exe is the most familiar.

Anything that can be run by double-clicking is called a program!

Viruses are programs!

Question 8: What are the computer software systems? 1, personal safety

Physical security refers to the prevention of accidents or man-made damage to specific physical equipment, such as servers, switches, routers, cabinets, lines, etc. The keys to the computer room and cabinet must be well managed. Don't let irrelevant personnel enter the computer room at will, especially the computer room in the network center, to prevent vandalism.

Step 2 set up security

Setting security refers to making necessary settings (such as passwords of servers and switches) on devices to prevent hackers from gaining remote control of hardware devices. For example, many network administrators usually don't set the necessary passwords on manageable servers or switches. People who know network equipment management technology can gain control of servers or switches through the network, which is very dangerous. As the router belongs to the access equipment, it is bound to be exposed to the vision of Internet hackers, so it is necessary to take stricter security management measures, such as password encryption and loading strict access lists.

Security protection of software system

Compared with hardware system, the security problems of software system are the most and the most complicated.

Now TCP/IP protocol is widely used in various networks. However, TCP/IP protocol originated from the Internet. In the early days, the Internet was an open Internet for researchers and a completely non-profit information sharing carrier, so almost all Internet protocols did not consider the security mechanism. Another factor of network insecurity is that people can easily obtain relevant core technical data from the Internet, especially technical data about the Internet itself and various hacker software, which can easily cause network security problems.

safety precautions

Facing the endless network security problems, we are not helpless. We can start from the following aspects to nip in the bud.

1. Install the patch

Any operating system has loopholes, and it is the responsibility of the network system administrator to patch it in time. Most small and medium-sized enterprise servers use Microsoft's Windows NT/2000/2003 operating system. Because there are so many users, so many bugs are found, and so many people deliberately attack. In order to make up for the security holes in the operating system, Microsoft has provided many patches on its website, and you can download and install related upgrade packages online. Windows2003 should be upgraded to at least SP 1, Windows 2000 should be upgraded to at least Service Pack 2, and Windows NT 4.0 should be upgraded to at least Service Pack 6.

2. Install and set up a firewall

Now there are many firewalls based on hardware or software, such as products of Huawei, Digital China, Lenovo and Rising. For intranet, it is very necessary to install firewall. Firewall has a good preventive effect on illegal access, but everything will be fine after installing the firewall, but it only needs to be set correctly to work. If you don't know the firewall settings, you need to ask technical support personnel to help set them up.

3. Install network antivirus software.

Now that the virus is rampant on the Internet, everyone must have tasted the power of Nimda virus. This requires installing online antivirus software on the network server to control the spread of the virus. At present, most anti-virus vendors (such as Rising, Guanqun Gina, Trend, Symantec, Panda, etc. ) have launched online antivirus software. At the same time, when using online antivirus software, it is necessary to upgrade the antivirus software regularly or in time.

4. Account number and password protection

Account and password protection can be said to be the first line of defense of the system. At present, most of the attacks on the system on the Internet start from intercepting or guessing passwords. Once a hacker enters the system, the previous defense measures are almost useless, so it is very important to manage the account and password of the server system administrator to ensure the system security.

The password of the system administrator must have a large number of digits, at least 8 digits, and cannot be set as an easily guessed password, such as your own name and date of birth. For ordinary users, set certain account management strategies, such as forcing users to change their passwords once a month. Close some unusual accounts, such as anonymous login accounts.

5, monitoring system log

By running the system log program, the system will record all users' use of the system, including ... > >
