Maybe everyone has heard of Unicode, UCS-2, UTF-8 and other words, but what they specifically mean, what is the principle
The back line is in recent years in DIY assembly computer, more often heard, belong to the DIYer of professional terminology. In simple terms, the back line is for the computer chassis, as long as the chassis and power support to go back line, in the installed time, it can be internal wire to achieve the most streamlined and tidy, not only beautiful appearance, late maintenance is also convenient, and also
, from the location code to the inner code, you need to add A0 on the high and low byte respectively.In DBCS, GB internal code storage format is always big endian, that is, high in front.The highest bit of the two bytes of the GB2312 is 1. But the code bit that meets this condition is only 128*128=16384. So the low-byte highest bits of GBK and GB18030 are probably not 1. However, this does not affect the parsing of DBCS character streams: When reading a DBCS character stream, you can encode the
I do not know if you have ever encountered the case of computer chassis leakage, when you touch a part of the body of the computer chassis shell, an instant there is a clear feeling of electricity. This is a common in our lives a kind of chassis leakage phenomenon, that this is normal? What is the cause of leakage of computer
With the arrival of summer, room temperature significantly elevated, many friends of the computer began to appear due to poor heat caused by the blue screen crash and so on. For computer users, it is generally possible to clean the dust and the chassis plus the cooling fan to improve the computer's cooling capacity, personal advice to clean up the dust and add a cooling fan two-pronged approach. Now the question is, what about the power supply for the
The user's UCS Manager, found chassis 2 6th slot fan Alarm, led does not light, the slot fan and other normal slot fan interchange, the fan is working properly, but the original good fan inserted in the 6th slot, still alarm, LED does not light. The initial judgment should be the problem with the knife case. A case was opened to Cisco and the Cisco TAC Engineer was connected remotely to 6248, and the comman

the initial Unicode encoding is a fixed-length , 16-bit, or 22-byte representation of a character, which can represent a total of 65,536 characters. Obviously, it is not enough to represent all the characters in a variety of languages. The Unicode4.0 specification takes this into account, defines a set of additional character encodings, which are represented by 2 16-bit characters, so that up to 1,048,576 additional characters can be defined , and currently unicode4.0 only defines 45,960 additio
The two-wheel differential model of the robot chassis, is the most common robot chassis, such as sweeping robots, tracking cars and so on. As a moving part of a robot, it needs to realize two functions of input and output.
Input: Receive control instruction speed V and angular velocity w (v,w)-unit m/s RAD/S
Output: Robot relative posture X, y axis coordinates, angle th (x,y,th)--unit M M RAD

ASCII and related standards
The earth people all know ASCII is the abbreviation of the American Standard Information Interchange code, also know that the ASCII stipulation uses 7 digits binary numeral to represent English character, the ASCII is designated as international standard after the code name is ISO-646. Since the ASCII code uses only 7 bits, that is, a byte can represent 256 digits, it uses only the 0~127 128 code bits, the remaining 128 code bits can be used to expand, to represent s
ASCII, gb2312, and GBK to gb18030 are both backward compatible. Among them, gb2312 and GBK to gb18030 both belong to the dual-byte character set (DBCS character set)Unicode is ANSI compatible. For example, the Unicode encoding of the Chinese character is 6c49, And the GB encoding is Baba.The Unicode name is "Universal multiple-octet coded chasracter set", for shortUCOS only specifies how to encode and does not specify how to transmit and save the encoding. For example, the "Han" character's
Recently, a number of Cisco ucs c Series servers have been added. After two weeks of deployment and installation, the server can finally be tested. This document briefly introduces the network configuration of the Operating System (centos 6) in the Cisco UCS server. It can be simply considered that this article describes the network configuration of a physical server connecting the NIC to the trunk mode por

This section describes the UTF-8 encoding.
When the content to be expressed is 7 bits, use one byte: 0 ********. The first 0 is the flag, the remaining space can represent the content of ASCII 0-127.When the content to be represented is between 8 and 11 bits, two bytes are used: 110*10*10 of the First and

So, how do I get the motherboard jumper? In fact, it is very simple, we just have a reason to think, one by one, it is easy to connect. Generally speaking, the main board jumper on the needle mainly includes switch power switch, reset switch (coincidence), power light, hard drive lights, speakers, audio, USB interface, and so on, seemingly a lot, but one to, it is not difficult, the following detailed introduction.

The Qianyi "Dragon ice five generations" 1U chassis adopts an innovative integrated design concept of "Chassis + radiator, A passive heat sink with a large heat dissipation area called "qianniu" is directly cooled by a powerful fan in the chassis, which greatly improves the air volume and heat sink area of the CPU cooling fan, it has produced epoch heat dissipati
Chassis generally include housings, brackets, panels on a variety of switches, indicators and so on. The shell is made of steel plate and plastic, and the hardness is high, which mainly protects the internal components of the chassis. The bracket is mainly used for fixing motherboards, power supplies and various drives.
There are many types of chassis
