Microsoft is a website that teaches java and phyton
Here is a Python program:
tmp = input().split(' ')
c = tmp[0]; s = tmp[1]
ans=0
for i in range(len(s)):
if s[i] == c: ans+=1
# the ans variable stores the number of occurrences
print(ans)
Answer:
Each pixel of light coming from your computer is made up of a combination of Red, Blue and Green light of different intensities. As this pixel of light is so small your eye only "sees" the combination of those 3 pixels as the intended colour. (as opposed to just red, green and blue light) (This is also known as additive colour mixing)
Answer:
Cloud computing as a virtual hosting tool, is much more theoretical. Both servers, applications, and communications are hosted in the cloud, off property, rather than being available via computer machine whereas In computing client/server, a controller gets client requests mainframes and needs to share its services, programs and/or data of one sometimes more client systems on the internet, and a client would be a portable platform that specific portions with a server and make use of a finite resource.
Explanation:
<u>Similar to cloud computing and client-server computing:
-
</u>
- The cloud computing and client-server networking underpinning principles are the same. That is contact between client and server.
- Throughout networking and client-server networking, user nodes can communicate (queries) with databases that live locally or are located in many other networks.
<u>Difference between computing and client-server computing:
</u><u>-
</u>
Resources:
-
- In computing client-server, the corporation or association controls the tools.
- The services are offered in cloud computing by third parties or other businesses.
<u>The purpose of cloud computing and client-server computing is different:-
</u>
- Client-server computing is targeted at use. In computation, client-server clients request a product from the cloud. The operating system runs the test, then returns it.
- Cloud computing is a sort of system in which the IT-related services are leased to the clients as a contract.
<u>Pros and cons of Cloud Computing:-
</u>
The Pros:-
- Lower costs for business:-The cloud is saving a lot of money for a medium-sized or small enterprise.
- Better Reliability:- A dedicated group of experts performs all programming with such a cloud computing alternative.
The Cons:-
- Limited Control:- When a firm stores cloud data, they have very limited control of it.
- There have been security issues. The cloud isn't too attuned for every company to position some information on even a cloud.
<u>Pros and cons of client-server computing:-
</u>
The Pros:-
- Improved data sharing:- Data stored via the normal business method and processed on a server is available over an approved connection for the intended users.
- Security:- Database has stronger access control and methods to ensure data could only be accessed or abused by approved clients.
The Cons:-
- Overloaded Servers:- When multiple simultaneous requests from the client are made, the server is significantly overloaded, causing congestion in traffic.
- Impact of centralized architecture:- Because it is centralized if a vital server fails to satisfy customer requests, the client-server then lacks good network robustness.
