I. Concept
The ad-hoc mode is similar to the previous direct connection twisted pair. It is a P2P connection, so it cannot communicate with other networks. Generally, wireless terminal devices such as PMP, PSP, and PMA use the ad-hoc mode. In the establishment of a home wireless LAN, I think everyone knows that the sim
Ad-hoc TestBasic knowledge about Ad-hoc Testing
"Ad-Hoc" is intended to refer to "specific, one-time", which specifically refers to "random, free" testing. In addition to testing according to the test samples and instructions, ran
Ad hoc is a Latin word that means "impromptu, temporary (improvised, impromptu)" in Latin.
The AD-HOC structure is a PEER-TO-PEER network structure which eliminates the wireless AP, so long as the computer installed the wireless network card can realize the wireless interconnection between each other; the principle is
In a nutshell, that's it.Ad hoc mode is Apple used to test for the unused app, first you need to apply for an ad hoc certificate on the Apple development Platform,Then generate an ad hoc profile file in profiles (just select the certificate at the time of the build), and the
What is ad hoc query this is just a note that I have never known what is ad hoc query. Today I read "SQLSERVER Enterprise Management Platform" again, I understand what is ad hoc queries below this sentence is my personal summary:
Meaning of Ad hocNo pre-planned or low-planned or unpredictable eventsOr indicate that the described thing is a stopgap, a deliberate plan, or an impromptu event .Ad hoc queries (adhoc query)Ad hoc query is based on the user's own needs, flexible choice of query conditions,
In today's diverse communication modes, wireless networks have given us many things we dream. For example, the use of Ad-hoc networks makes more technologies possible. We will study its routing protocol in detail. We all know that although wireless communication systems differ in application scenarios, costs, and the maximum access rate, they share some common characteristics, that is, infrastructure must b

This is only a note.
I have never known what ad hoc queries are. I read them again today.Sqlserver enterprise management platform,To understand what is "ad hoc queries"

Before completing the iOS development and preparing for the release, we wanted the app to test, comment, modify, and then post to the app store around friends.

China's routing technology is still developing very rapidly, and new technologies are constantly emerging. Ad hoc technology is one of them and has gradually become a hot topic in wireless communication. Adhoc technology research started in 1970s.
