unified logical address (IP address). In this way, the differences between the Mac frames of these different physical networks no longer exist on the upper level. As a result of this transformation, the interconnection of different types of physical networks is realized. both TCP and UDP are transport-layer protocols.TCP (transmission Control Protocol, transmission Protocol) is a connection-oriented protocol that must be connected to each other before sending or receiving data.UDP (User data Pr

. However, the above methods are mainly used in non-real-time application scenarios.SummarizeTypically, the more partition in a Kafka cluster brings higher throughput. However, we must realize that the partition of the cluster is too large or the single broker node partition too much, which will have a potential impact on the availability of the system and the message latency. In the future, we plan to make some improvements to these limits, making Kafka more extensible in terms of the number of

Description:Consider equations having the following form:a*x1*x1 + b*x2*x2 + c*x3*x3 + d*x4*x4 = 0 A, b, C, D is integers from the I Nterval [ -50,50] and any of them cannot is 0. It is consider a solution a system (X1,X2,X3,X4) that verifies the equation, Xi is an integer from [ -100,100] and Xi! = 0, any i∈{1,2,3,4}. Determine how many solutions satisfy the given equation.Input:The input consists of several test cases. Each test case consists of a containing the 4 coefficients a, B, C, D, sepa

Project-linked list class "Dynamic linked list is also a very useful data structure in program design. It can be said that whether you can understand the principle of operation, determines whether you are eligible to be called "a".

char *p=" Hello"; 4 return p; 5 }There are readers here who will ask, not all a pointer p pointing to the string "hello!" It? Why is the result different?Let's take a look at the process of the above modified program:As you can see, p holds "hello!" when defined as a pointer type Address in the static store, so p is given to STR, and printf ("%s", str) can print out the hello!Through the phenomenon to see the essence1, when defined as Char p[]= "hello!";, p is fixed and is a pointer co

Although Richard's book is good, what he wants to express is to let you know. For those who want to be proficient in TCP, it is far from enough. You still need more time to understand why, and reading the RFC document is the best way, in this way, you will understand why TCP is designed. The RFC document corresponding to the TCP core topic is summarized here for your convenience. :) RFC serial number Topic Description 793 TCP standard The original TCP
