What does computer offline mean?

The computer offline state means that the computer is not connected to the network and accesses previously cached web pages. Every time a user logs in to a website, the browser will save each web page opened by the user in the form of a cache file in the internet cache folder, so as to speed up the login time the next time the user clicks on the web page, and at the same time It allows users to use the offline function without being connected to the Internet to browse web pages that the user has logged in to online. The benefits are self-evident.

The offline state means that the computer is not connected to the network. Offline is a state of being disconnected from the network and accessing previously cached web pages without being connected to the network.

Offline introduction

The offline state means that the computer is not connected to the network, usually after the browser is opened, the browser is not connected. When you go to the Internet, the browser will default to offline browsing (browsing away from the Internet) because the web pages you usually browse will be stored on the local machine, so you can still browse the information you have browsed after disconnecting from the Internet.

Offline work

Offline work is to browse the web page without being connected to the network, as mentioned here The network connection refers to the server of the specific website you log in to. Every time you log in to a website, the IE browser will save each web page you open in the form of a cache file in the interne cache folder. This will speed up your login speed the next time you click on the webpage. It also allows you to use the offline function to browse webpages you have logged in to online when you are not connected to the Internet. The benefits are self-evident.

Definition of offline processing

Offline processing is a computer technology that refers to external processing that is not controlled by the host. Data processing is performed on the equipment, or data processing that is not directly connected to the real-time control system or host. It is often used in data processing where the host speed is not high to improve equipment utilization.

Features of offline processing

During offline processing, the data on the external device requires a long waiting time before being processed. When there is data input, the host does not process it. It just stores the data from the external device in the buffer. Once the buffer is full or the waiting time is up, the host will process it.

The development history of offline processing

When computers were used manually in the early days, operations and input and output were all online. , it is directly controlled by the central processing unit, and the operation time is very long. As the computer speed continues to increase, the central processing unit has to wait for slow online input and output devices during input and output operations, and cannot fully exert its due efficiency. For this reason, Offline input and output is introduced in batch processing: a small microcomputer is set up in addition to the host computer. This computer only interacts with external devices, inputs the information to be processed into high-speed auxiliary memory in batches, and then transfers the auxiliary The memory is connected to the host.

Advantages and Disadvantages of Offline Processing

Offline processing can improve equipment utilization, but requires operator intervention. It is suitable for batch processing. After all a batch of jobs are input into the auxiliary memory, the host starts to process them one by one. After all the batch of jobs are processed, the microcomputer separates them. During the processing of the batch of jobs, if a new one comes Even if the job is an urgent task and does not take a lot of processing time, the system cannot process it. It can only put it in the next batch and wait for this batch of jobs to be processed before processing, so the flexibility is poor.
