Swap space plays an important role in Linux systems, especially when the system is low on memory. It acts as a backup memory storage space that helps the system run smoothly and maintain stability even under high load. This article provides you with a detailed guide to adding swap space on Ubuntu 22.04LTS to ensure that your system performance is optimized and can handle various workloads. Understanding Swap Space Swap space provides virtual memory that is used to supplement the system's physical RAM. When the system is low on RAM, the kernel swaps data to disk to prevent out-of-memory and system crashes. Linux systems commonly use swap space to handle this situation.

In machine learning, a basic concept is how to judge the difference between two samples, so that the similarity and category information between the two samples can be evaluated. The measure to judge this similarity is the distance between two samples in the feature space. There are many measurement methods based on different data characteristics. Generally speaking, for two data samples x, y, define a function d(x, y). If it is defined as the distance between the two samples, then d(x, y) needs to satisfy the following basic properties : Non-negativity: d(x, y)>=0 Identity: d(x, y)=0 ? x=y pair

The remaining space on the c drive is 50-80G which is more suitable. Since the system will generate junk files, cache files, etc. in the future, it is recommended to reserve at least 50GB-80GB of space for the C drive; if you are not used to choosing a path when installing software and do not clean your computer frequently, then at least 100GB is required. .

1. Introduction Due to the explosive growth of current computer networks, the ensuing problem is the rapidly increasing number of network attacks. Various sectors of our society, from government departments to various critical infrastructures in society, are heavily dependent on computer networks and information technology. Apparently they are also vulnerable to cyberattacks. Typical network attacks disable the target computer, take services offline, or access the target computer's data. The number and impact of cyberattacks has increased significantly since the 1990s. Network security refers to a set of technologies used to protect network device activities and measures to protect them from all possible threats. In traditional network security technology, most of them are static access management, and the security control system will protect based on preset definitions.
