Answer:

B. Computer operating system

Explanation:

the operating system (or OS) manages all of the hardware and software in the computer, and allows hardware and software to communicate.

We can also figure this out by process of elimination: Application software is just a fancy way to say apps, Graphical User Interface (or GUI) are menus that allow a user to use the computer through a visual representation (what you interact with using your mouse), and microcomputer just means a small computer like a laptop or a phone.

Alika [10]

Answer:

All these can be done using PKI.

Explanation:

PKI or the private key infrastructure is a new way to encrypt the data transfer or the retrieval along with the network among various terminals. The communication can be single node, hierarchical, bridge, mesh and hybrid. In the case of mesh, the connection can be established between each terminal. However, the connection can be established in between each pair via a network which can be a private network or it can be via the internet. However, the channel is required to be encrypted, or else the data can be hacked and attacks like a man in the middle attacks are quite on cards certainly. And this can be done using the PKI, which can be installed using the Certificate Authority and Public-private key pair generator. Suppose a connection is to be established between each node. And for this, you need to generate the certificate, which is generated by the Certificate Authority. And this is generally a third party like Godaddy, Verisign, etc. You can make use of the CSFFL as well. The free certificate authority Let’s Encrypt makes use of the CSFFL. And you must be using a web server as well like Apache that comes with services like OpenSSL that can be used to generate the certificate, and you can have your root Certificate Authority. That issues the certificate to the issuing certificate authority and the issuing certificate authority after registration confirmation by a person or a Robot, issues the certificate to the node which is requesting access to another node. And this certificate has the personal details of the requesting node and information about the webserver or node to which the requesting node is opting for a secure connection. The Certificate, when received by the webserver, is then matched with the certificate copy kept at the Root Certificate Authority. These days we also have the certificate revocation authority and Google has come up with Certificate transparency. So we can build our certificate authority, or we can have online certificate authority. These certificates also have the digital signature, which can be decrypted via the private key that is kept with the sender. The public key is sent to the certificate authority, and it decrypts it with the public key. And certificates are distributed among various types of trusts, which can be single, hierarchical, bridge, mesh and hybrid. And for each application, we have different certificates. Thus issues like non-repudiation, check over unauthorized access, restrict access to the resources, etc, can be ensured with the help of the PKI. And thus, we can secure the whole network at various levels like application level, transport-level, etc. Also, the company network can be bridged with the client or the business partner company if required using bridge level trust. However, we can also have a hierarchical level of trust. And thus we can secure the network using PKI and also confirm all the issues mentioned in the question are resolved. However, certificates are also being generated by Windows server 2012, and we can make use of it as well.

What technique involves graphical methods and nontechnical language that represent the system at various stages of development a

Mnenie [13.5K]

Answer:

The answer to this question this "modeling".

Explanation:

In this question, the answer is modeling because in system design we use System Analysis and Design(SAD). It is the most important subject in any software design like a mobile application, website, web pages, etc. In this subject, there is an important topic that is SDLC. The term SDLC stands for systems development life cycle or it is also known as the software development life cycle. It is a conceptual modeling used in project management that describes the stages involves the information for system development project. It maintenance the complete application. SDLC applied to technical and non-technical systems. In the SDLC many phases can be given as:

Requirement gathering and analysis:

In this phase, all the relevant information is collected from the customer to develop a product as their expectation.

Design:

In the design phase, the requirement gather by the software requirements specification (SRS) in a document that is used for software architecture.

Implementation or coding:

After completing the design phase we implement/coding in that section like User input validation, admin work, payment management, etc.

Testing:

In this section, we test all the things in software before hand over to the customer.

Deployment:

In this section after completing the testing successfully. it goes to the deployment section in this section production environment or User Acceptance testing is done depending on the customer expectation.

Maintenance:

In the maintenance section when the product is hand over customer and in future if any issue comes up and needs to be fixed or there is any Up-gradation is needed So it is done by the developers.

In computer science, any development is done on modules. So the answer to this question is modeling.
