1. How much is a customized software? How much does it cost to customize and develop small programs? Now follow Xiaobian to have a look
the cost of custom developing a small program usually costs thousands to tens of thousands of yuan. The specific amount depends on your needs. For example, what kind of applet are you going to develop? What functions do you want to achieve? How many pages? What is the style of UI? There are no external interfaces or embedded systems, etc
it mainly depends on your functions. The outsourcing company also depends on the difficulty of small program development and the required working time to determine the cost
(1) we have our own development team
the development of small programs needs the technical support of front-end and back-end. We won't talk about the simple display of small programs, which most businesses won't choose
we are talking about a small program with display and online sales. Of course, some people can develop a small program independently, but the corresponding development progress will be relatively slow. In addition, the salary of this kind of developer is not low. If you ask him to develop it, the later maintenance will be him, and the cost will be much higher
if it's a team, the development progress will be much faster. In addition, after the development is completed, you only need to pay the market price and leave one or two people to maintain it (normally one person is enough). This is more suitable for large enterprises, with strong financial support
(2) find a professional development company to outsource
write the requirements directly. The outsourcing company will develop the procts according to your needs. After the development, you can directly use the procts. Although it also takes a certain time, the price is not low, and the salary level of your own type of work is not low, generally, this kind of team develops more small programs than you have ever seen, so it is needless to say that it is professional. It is suitable for medium-sized enterprises, has its own customized needs, and can bear the development cost
(3) purchase code package
in the early months, there were a lot of those who sold small program code package on the network, some of them were real and some were fake. Let's not talk about the fake, just pay attention to it. This kind of small program is usually a small program template, and there is no personalized design. Just buy the code package and deploy the server to install it, Of course, it also needs a certain it foundation, and the price will be much cheaper than the first two options. For small programs with similar functions, the price of the code package is almost one tenth of the development price, but the quality of the code package can not be guaranteed. It is recommended to find a professional to check the test code package. In addition, you need to maintain the code package yourself, Therefore, this method is more suitable for those who have the ability and foundation and can't develop by themselves for other reasons. Can rece expenses.

5. The so-called blockchain is an unreliable way for e-commerce to raise funds. Not long ago, the unit issued a notice not to involve the so-called blockchain technology.
6. There are a lot of jobs designed by them, which are usually daily activities. In terms of the work done by a social worker in a community welfare home, for example, giving some psychological health guidance to the elderly, playing a game with the children, or doing some programs or activities for the elderly ring festivals, so that they can have fun or joy, and feel the care of the society for them, Or a missing understanding.
7. Welfare home is a kind of welfare home established by the state, society and organizations to help people in social difficulties and patients with diseases, which is used to provide them with food, clothing, accommodation or medical conditions. The welfare home has the condition to open classes by itself, and send the nearby schools to study unconditionally. Infants and young children should be given priority to care, and preschool ecation should be carried out at the same time
for those with incomplete limbs but sound intellectual development, the combination of nursing, treatment and teaching should be implemented. On the one hand, rehabilitation treatment was given to enable them to take care of themselves; On the other hand, vocational ecation and skill training should be provided to create conditions for them to enter the society in the future. For children with dementia, emphasis should be placed on training their ability of self-care and simple labor<
extended data:
the social role of welfare institutions:
first, the service objects of welfare institutions have generally changed from the traditional & quot; Three no & quot; At present, the number of self financed adoptions by state-owned welfare institutions has reached more than 40%< Second, a large number of private social welfare institutions have emerged
Third, we should use the existing resources of the community to set up welfare undertakings, and replace idle nurseries, kindergartens and enterprises with old-age care and service institutions< Fourth, the funds for setting up welfare undertakings are only invested by the government and graally diversified. The state, collectives, associations, foreign investors and indivials jointly contribute to the construction

8. In fact, a router can be regarded as a single function computer. The configuration of computers varies greatly, so does the natural price< Main parameters of Router:
1) CPU
CPU is the core component of router. Different series and models of routers have different CPU. The quality of the processor directly affects the throughput of the router (routing table lookup time) and routing computing ability (network routing convergence time)
generally speaking, the processor with a dominant frequency of 100m or less belongs to a lower dominant frequency. Such a low-end router is suitable for ordinary families and SOHO users. 100m to 200m belong to the medium frequency, 200m above belong to the higher frequency, suitable for Internet cafes, small and medium-sized enterprise users and large enterprise branches
2) memory
memory can be either byte or bit, but the difference between the two is 8 times (1byte = 8 bit). In the current router memory, 1m to 4m bytes are low, 8m bytes are medium, and 16m bytes or more are large
3) throughput
the data in the network is composed of one packet, and the processing of each packet costs resources. Throughput refers to the number of packets per unit time without packet loss, that is, the ability of the whole device to forward packets, which is an important indicator of device performance. Router throughput represents the amount of data that a router can process per second, which is an intuitive reflection of router performance
4) support network protocol
just as people speak in a certain language, there is also a language between computers on the network, which is network protocol. Different computers must abide by the same network protocol to communicate. Common protocols are: TCP / IP protocol, IPX / SPX protocol, NetBEUI protocol, etc. IPX / SPX is widely used in LAN. If users access the Internet, they must add TCP / IP protocol to the network protocol
5) line speed forwarding capability
the so-called line speed forwarding capability means that when the maximum speed of the port is reached, the data transmitted by the router does not lose packets. The most basic and important function of router is packet forwarding. Forwarding small packets at the same port rate is the biggest test of the router's packet forwarding ability. The full plex line speed forwarding ability refers to the minimum packet length (64 bytes for Ethernet and 40 bytes for POS port) and the minimum packet interval (in accordance with the protocol) to transmit two-way on the router port without packet loss
line speed forwarding is an important index of router performance. In short, it means that as much traffic as comes in, as much traffic as goes out. The throughput will not decline because of the processing capacity of the device
6) the number of computers with the router is easy to understand, which is the number of computers that the router can load. In the performance parameter table introced by the manufacturer, it is often seen that the nominal router can bring 200 pcs and 300 pcs, but in many cases, the performance of the router is very different from the nominal value. This is because the number of routers with machines is directly affected by the network busy degree of the actual use environment. The number of routers with machines varies greatly in different network environments
for example, in Internet cafes, almost all people are chatting, playing games and watching online movies at the same time. These data have to go through the WAN port, and the router has a heavy load. However, only a small number of people are using the network at the same time in the enterprise network, and the router load is very light. Therefore, if you put a router in the enterprise network that can carry 200 pcs into the Internet bar, you may not be able to carry even 50 PCs. It is not accurate to estimate the average data flow of each PC in a network.
