development materials :
1. Clothing refers to the general term of clothes, shoes, bags, toys and accessories, and mostly refers to clothes. Clothing has appeared in the early development of human society. Ancient people used all kinds of materials they could find to make crude "clothes" to protect themselves. The first clothes of human beings were made of animal skin, and the earliest "fabric" that wrapped the body was made of hemp fiber and grass
2. In the national standard, clothing is defined as sewing, wearing on the human body to protect and decorate the proct, also known as clothing
3. In today's society, clothing is a necessary thing for everyone to decorate themselves, protect themselves, and give themselves and their families. It is not only for clothing, but also for an identity, an attitude towards life, and an expression of personal charm
Clothing can protect human body and maintain the heat balance of human body to adapt to the impact of climate change. In order to make people feel comfortable, the main factors that affect the comfort are the fiber properties in the materials, beauty specifications, fabric structure, thickness and sewing technology5. The clothing appeared at the beginning mainly for the purpose of covering up shame. After the development of time, it turned to functionality (practicality), and then paid more attention to the beauty of clothing to meet people's spiritual enjoyment of beauty. The main factors affecting the aesthetics of textiles are texture, color, pattern, fabric organization, shape retention, drapability, elasticity, crease resistance, clothing style, etc
the ID of the key is a part of the information used by the manufacturer to manage the vehicle, which is used to match the key for you in the future
1. The meaning is different
SKU = stock keeping unit, which is used to represent a single style, single color and single code on clothes. It is used to go through the data system. The contents of purchase, sales and inventory, data analysis, etc. are reflected here
SKC = stock keeping color unit, used on clothes to indicate single style and single color, which is used for daily communication. For example, the number of SKCS ordered this spring means the number of styles and colors
2
Each proct ofSKU has a unique SKU number. For a commodity, when its brand, model, configuration, grade, color, packaging capacity, unit, proction date, shelf life, use, price, origin and other attributes are different from other commodities, it can be called a single proct
SKC comes from the purchase, sale and inventory management of clothing instry. In the early days, the IT level of clothing sales companies was low. Before going to the system, it was necessary to check and record by hand to record the number of each color of each model without recording the size. Therefore, single model and single color is the minimum inventory management unit
3
SKU refers to a proct, and each proct has a SKU, which is convenient for e-commerce brand identification. If a proct is multi-color, there are multiple SKUs. For example, if a garment has red, white and blue, the SKU codes are not the same. If it is the same, there will be confusion and wrong goods
SKC is "international bar code" single color, no longer need to number
The full name of SKU is the stock keeping unit. A single model, single color and single code is used to go through the data system. The purchase, sales and inventory, data analysis and other contents are reflected here
the full name of SKC is stock keeping color, which is used for daily communication? Just how many colors
extended data:
in e-commerce operation and warehouse management, SKU contains three aspects of information:
1. From the perspective of goods, SKU refers to a single commodity, and its goods attributes have been determined
as long as the proct attributes are different, they are different SKUs. Attributes include many, the general understanding of goods attributes include: brand, model, configuration, grade, color, composition, use, etc. In other words, the same goods need to be defined as different SKUs as long as they are stored, managed, sold and served in different ways
2. From the perspective of business management, SKU also contains the information of goods packaging unit
e to different units of measurement (packaging units), for business management needs, they should be classified into different SKUs. Of course, there can be a unit conversion algorithm to help convert SKUs. Another example: a pair of socks is a SKU. If the other parameters are the same, they are only sold in packages (12 pairs) based on the unit of dozen. They also belong to different SKUs
From the perspective of information system and goods coding, SKU is just a codedifferent commodity (commodity name) has different code (SKU). This code is one-to-one associated with the defined goods, so that inventory and sales can be recorded and analyzed according to the data of different SKUs. When using WMS or ERP system, we will find that every SKU code has the precise meaning of commodity information
1. North bridge chip: (North Bridge) is the most important part of the motherboard chipset, also known as the host bridge. Generally speaking, the name of the chipset is named after the name of the north bridge chip. For example, the north bridge chip of the Intel 875p chipset is 82875p, and the latest is 82945p, 82945g, 82945gz, 82945gt, 82945pl, 82955x, 82975x and other seven North Bridge chips of the 945 / 955 / 975 series supporting al core processors
role of North Bridge: North Bridge chip is responsible for connecting with CPU and controlling memory (only limited to Intel CPU, amd Series CPU has integrated memory controller in CPU since K8 series, so amd platform's north bridge chip does not control memory), AGP data is transmitted in North Bridge, providing the type and dominant frequency of CPU, front-end bus frequency of system, and memory type (SDRAM, DDR SDRAM and RDRAM, etc.) and maximum capacity, AGP slot, ECC error correction, etc. the north bridge chip of the integrated chipset also integrates the display core
North Bridge identification and features: the north bridge chip is the chip on the motherboard closest to the CPU, which mainly takes into account the closest communication between the north bridge chip and the processor, and shortens the transmission distance in order to improve the communication performance. Because the data processing capacity of the north bridge chip is very large, the heat value is also increasing, so now the North Bridge chips are covered with heat sink to enhance the heat dissipation of the north bridge chip, and some of the North Bridge chips of the motherboard also cooperate with the fan for heat dissipation. Because the main function of the north bridge chip is to control the memory, and the memory standard changes as frequently as the processor, so the North Bridge chips in different chipsets are definitely different. Of course, this does not mean that the memory technology used is completely different, but there must be some differences between the North Bridge chips in different chipsets
2. South bridge chip: South Bridge chip is an important part of the motherboard chipset. It is generally located on the motherboard far below the CPU slot and near the PCI slot. This layout takes into account that it is connected to more I / O buses, which is concive to wiring if it is far away from the processor. Compared with the north bridge chip, its data processing capacity is not large, so the south bridge chip generally does not cover the heat sink. The Nanqiao chip is not directly connected with the processor, but is connected with the Beiqiao chip in a certain way (different chipsets from different manufacturers, such as Intel hub architecture from Intel and multi threaded "Miaowu" from SIS)
role of South Bridge: South Bridge chip is responsible for the communication between I / O buses, such as PCI bus, USB, LAN, ATA, SATA, audio controller, keyboard controller, real-time clock controller, advanced power management, etc. these technologies are generally relatively stable, so the south bridge chip may be the same in different chipsets, but the north bridge chip is different. Therefore, the number of North Bridge chips in the motherboard chipset is far more than that of South Bridge chips. For example, the 430tx of socket 7 and 440LX of slot 1 of Intel's early chipsets with different architectures all use 82317ab as their South Bridge chips, while the chipsets 845E / 845G / 845GE / 845PE and other configurations in recent two years all use ich4 South Bridge chips, but they can also be used with ich2 South Bridge chips. What's more, some motherboard manufacturers use procts from different chipset companies, such as kg7 raid motherboard, amd 760 and via 686B. The development direction of Nanqiao chip is mainly to integrate more functions, such as network card, raid, IEEE 1394, even Wi-Fi wireless network and so on< Power management chip is also known as power IC, also known as pulse width molation chip (PWM). The main board is called programmable pulse width molation chip, which is mainly responsible for controlling the main power supply of CPU. It is generally located near the CPU socket.

SKC: single, monochrome
1. SKC refers to single, monochrome, and C is color
2. SKC comes from the purchase, sale and inventory management of clothing instry. In the early days, the IT level of clothing sales companies was low. Before going to the system, they checked and recorded by hand. The number of each color of each model was ok, and the size was not recorded. Therefore, single model and single color was the minimum inventory management unit
3. SKC spread in the early clothing instry, and its scope was limited. It can not meet the needs of fine management now, and is graally replaced by SKU.
SKU is a single model, single color and single code, which is used to go through the data system. The purchase, sales and inventory, data analysis and other contents are reflected here
SKC is single and monochrome, which is used for daily communication. For example, how many SKCS will you order this spring? Just how many colors.
if you want to shut down, buy an authentic instrial control valve.
