How to install the unit manual reimbursement system

Prepare the system CD-ROM: If there is no You can go to the computer store to buy the latest version of the CD of any system you need to install. If you have a burning optical drive, you can also download the ISO format system file on the Internet and burn it to the system CD.

The installation of the hospital's medical system requires authorization. In theory, all computers are an intranet.It can't be connected with the outside. All computers must have a unique id, and then the administrator's authorization is required. If you need an external network connection, you need higher permissions. Only one person in your hospital should have this highest permission password.

Manual operation, batch processing system, what are the characteristics?

Characteristics of manual operation: manual operation, exclusive way.Batch processing system The batch processing system is a system software loaded on the computer. Under its control, the computer can automatically and batch process one or more users' jobs (this job includes programs, data and commands).

Batch processing system: The operator loads the operation into the computer in batches and runs it by the computer. Users cannot intervene during the operation of the program. Therefore, the characteristics of the batch processing system are: users use computers offline, batch processing of jobs, concurrent execution of multiple programs in the system, and poor interaction ability.

Multiple channels: Multiple jobs are stored in memory at the same time, and only one job runs at a time. These jobs share resources such as CPU and external devices. Batch: There is no interaction between the user and his homework. Users themselves cannot interfere in the operation of their own homework, and find that homework errors cannot be corrected in time.

Two characteristics of manual operation mode: (1) The user monopolizes the whole machine. There will be no waiting phenomenon because the resources have been occupied by other users, but the utilization rate of resources is low. ( 2) CPU is waiting for manual operation. The CPU is not fully utilized.

Batch processing operating system batch processing means that the user no longer intervenes after submitting a batch of jobs to the operating system, and the operating system controls their automatic operation. This kind of operating system that adopts batch processing operation technology is called batch processing operating system. The batch processing operating system is divided into single-channel batch processing system and multi-channel batch processing system.

Manual operation in the development history of the operating system (without operating system)

1. Manual operation (No operating system): The first computer was born in 1946 - in the mid-1950s, the operating system had not yet appeared, and the computer work was operated manually. Two characteristics of manual operation: (1) The user monopolizes the whole machine.

2. The first computer was born - in the mid-1950s, the operating system had not yet appeared, and the computer work was operated manually.

3. Manual operation stage: This is the initial stage of the development of the operating system. At this stage, all parts of the computer are completely operated manually. The user loads the program into the computer, and then the operator manually executes the program and processes the results. The main problem at this stage is low efficiency, high error rate, and extremely high requirements for operators.

4. HandWork operation controls the basic functions of the computer through some hard wiring on the plug-in board. The programming is all in machine language, and there is no programming language (not even assembly language), let alone the operating system. At this time, in fact, all the questions are numerical calculation problems.

5. Users monopolize the whole computer: In the era without operating system, users can monopolize the entire computer system. CPU waits for manual operation: In the era of no operating system, the utilization rate of CPU is insufficient. Lack of resource management and task scheduling: There is a lack of resource management and task scheduling functions in the era without operating systems.

6. The development of operating system technology Manual operation *** No operating system *** The first computer was born in 1946 - in the mid-1950s, there was no operating system, and the computer work was operated manually.

The suffix method of manually deleting the system exe virus file

In the system.ini file, there is a "shell=file name" under [BOOT].

Step 1: Click "Start"-Run", type msconfig Enter, check your startup items, and prohibit exeplorer.exe from starting with the system. Step 2 "Then find the C: Program FilesInternet Explorer directory: the red circle is the virus file, shift+delete to kill it.
