Answer:
Error detection.
Explanation:
Tcp is a transport layer protocol. It is said to be connection oriented because it requires a handshake or established connection between the sender and the receiver.
Once a handshake is made, the segments of the packets are sent across and the connection is closed.
The error detection does not only carry out integrity checks, but allows for sequence numbering from the sender to receiver. If the packets arrives out of order, the sequence numbers are used to arrange them in the correct order.
Answer:
Handle the exception in a catch block or throw the exception to the method that called this method.
Explanation:
The try and catch statements occur in pairs. The try statement allows the user to define a block of code to be tested for errors while it is being executed.
The catch statement allows the user to define a block of code to be executed, if an error occurs in the try block.
If an exception is checked by a method, the method either handles the exception in a catch block or throw the exception to the method calling it.
Answer: A. > interesting.txt
Explanation: From the command line, one can perform numerous tasks from navigating into a directory, creating a new directory, deleting files, create files, modify files and so on using simple commands. In the scenario above, after using a common which is used to produce an output on the screen, such as the 'echo' command, one may wish to save the file giving the user the ability to access the file later. Since it is stated the file name 'interesting.txt' given to the file does not currently exist, appending the sign > saves the file. If the filename already exists, it will overwrite the existing content.
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.
