Article Introduction：The unit of channel transmission rate in data communication is bps, which means "bits/second" or "bits/second". That is, the data transmission rate is numerically equal to the number of binary bits that constitute the data code transmitted per second, also called "bit rate". ". The bit rate represents the number of bits transmitted per unit time and is used to measure the transmission speed of digital information; based on the number of bits occupied by each frame of image storage and the transmission bit rate, the speed of digital image information transmission can be calculated.

Article Introduction：IP address is a network protocol address commonly used on the computer Internet. Common formats include IPv4 and IPv6. The IPv4 address is represented by four 8-bit binary numbers. Each binary number ranges from 0 to 255. The range of each binary number is separated by ., for example 192.168.1.1. In a program, sometimes it is necessary to convert an IP address into a corresponding integer, or to convert an integer into a corresponding IP address. This involves conversion between IP addresses and integers. In PHP programs, we can use some built-in functions to implement IP addresses and integers

Article Introduction：In front-end development, jQuery is often used to implement various operations. Among them, replacing placeholders is also a common requirement. For example, in a string, there are some placeholders that need to be replaced according to different data. At this time, you need to use jQuery to replace placeholders. 1. Definition of placeholder Placeholder refers to a special character used to place a place in a string. Usually the form of placeholder is {}, where {} is the left and right brackets. For a string containing placeholders, you need to first define the position and number of placeholders, and then proceed based on the incoming data.

Article Introduction：BitMap Modern computers use binary (bit, bit) as the basic unit of information. 1 byte is equal to 8 bits. For example, a big string is composed of 3 bytes, but it is actually expressed in binary when the computer stores it. Big respectively The corresponding ASCII codes are 98, 105, and 103, and the corresponding binary codes are 01100010, 01101001, and 01100111. Many development languages ​​provide the function of operating bits. Proper use of bits can effectively improve memory usage and development efficiency. The basic idea of ​​Bit-map is to use a bit to mark the value corresponding to an element, and the key is the element. Since data is stored in bit units, the storage

Article Introduction：With the rapid development of computer technology, bit operations have become one of the important concepts in computer science. PHP is no exception, it provides a set of functions for performing bit operations. This article will introduce in detail how PHP implements bitwise operations. 1. Bitwise AND (&) operation Bitwise AND operation refers to performing an "AND" operation on the values ​​​​in the corresponding bits of two binary numbers, that is, only when the two corresponding binary bits are both 1, the result of the bit It is 1 only, otherwise it is 0. For example, perform a bitwise AND operation on 10100010 (162) and 01101011 (107)
