1 answer:

8 0

Before cellphones are able to be used to browse the internet, play games, record videos and take photos, its main purpose is similar to a telephone, albeit it is more portable. Early cellphones would not have games for you to play, not would it have emails for you to check, read, and reply to. Though ringtones might seem as an acceptable option, early cellphones would also have many selections or even any for you to choose.

Thus, the best option would be (B) contact list, which is necessary for a cellphone to have since the owner would need the number to be able to make a call.

Compare and contrast between Client/Server and Peer-to-Peer networks. What are some of the business benefits of using such netwo

fgiga [73]

Client/Server and Peer-to-Peer networks are the two major network architecture models in use today. They each have advantages and disadvantages that can be used to benefit a particular outcome.

Briefly, the client/server model relates to one or many client performing relatively simple requests, which are then executed by a server. The server is performing more complex tasks, and often interacting with many clients simultaneously. Examples of client/server models include most websites, including the Brainly page you are running right this instant. Your web browser is acting as a client, and the Brainly.com website is running as a web server. It receives simple requests or information from your browser, such as clicking on a question or text typed by your keyboard, and then acts on this information by consulting a database, returning values, or returning a whole new web page to your browser. The client/server model is very powerful in business as it allows powerful and secure server-side processing and relatively simple clients. Office 365 that runs all microsoft office suites such as word and excel in a web browser on 'the cloud' is an example of a highly sophisticated client/server architecture.

By contrast, peer-to-peer networks are a distributed architecture of equals. Instead of a simple client and complex server, all clients are equals and link together to form nodes on a distributed network. There is no central control (server) and each node acts as a client and server to other nodes. This is also an extremely powerful network; as there is no central control it is difficult to shut down a peer-to-peer network. Taking out one node will not break the network in comparison to the client/server architecture where if the server goes down, services halt. Prime examples of famous peer-to-peer networks are the Bitcoin network and similar cryptographic currency networks, and music and file sharing networks such as Torrents. The torrent tracker websites are client/server however once a torrent is loaded into a torrent downloading application, the file is collectively downloaded from hundreds of 'peers' across the world as part of the torrent peer-to-peer network.

faust18 [17]

Answer:

Following are the Pseudo Code to the given question:

Explanation:

Following are the pseudo-code by using the For loop:

Defines the A function (node, element)

The node is larger than 0.

if another value of the node equals its element

Loop Break

That element if node. value becomes lower than that

Node is node equivalent.

right

Using other nodes is node equivalent.

left

Node Return

If the node is vacant

print the Tree is empty

Following are the pseudo-code by using the while loop:

Defines the function A(node,element)

While this node is not zero.

if the value of the node equals the element

Loop Break

The element if node. value is lower than

Node is node equivalent.

right

Using other nodes is equivalent to an a.left node

Node Return

If the node is vacant

print Tree is empty

following are the Pseudo-code for recursion:

Set the function A (node, key)

If no root is the same as the root or no root.

return the root.

If the root value is lower than that of the quest for key return (root. right, key)

Return your lookup (root.left,key)
