write an algorithm and draw a flowchart for switching off a machine after it has made 500 glass bottles. use an appropriate conditional statement for this

Answers

Answer:

The algorithm is as follows:

1. Start

2. bottles = 0

3. While bottles != 500

  3.1 Create bottle

  3.2 bottle = bottle + 1

4. Switch off machine

5. Stop

See attachment for flowchart

Explanation:

This begins the algorithm

1. Start

This initializes bottles to 0

2. bottles = 0

The loop is repeated until 500 bottles is created

3. While bottles != 500

This creates a new bottle

  3.1 Create bottle

This increments the number of bottles by 1

  3.2 bottle = bottle + 1

This switches of the machine after all bottles are created

4. Switch off machine

End algorithm

5. Stop

Don's company has contracted with a service provider to receive a computing platform for all employees, complete with an operating system, database services, and a Web server. Don develops applications using tools delivered by the service provider. What type of service has Don's company signed up for?

Answers

Answer:

Platform as a Service (PaaS).

Explanation:

Cloud computing can be defined as a form of data computing which requires the use of shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives.

Basically, cloud computing comprises three (3) service models and these include;

1. Platform as a Service (PaaS).

2. Software as a Service (SaaS).

3. Infrastructure as a Service (IaaS).

Platform as a Service (PaaS) refers to a type of cloud computing model in which a service provider makes available a platform that allow users (software developers) to build code (develop), run, store information in a database and manage applications over the internet.

The main purpose of a Platform as a Service (PaaS) is to provide an enabling environment for software developers to code without having to build and maintain complex infrastructure needed for the development, storage and launching of their software applications.

Simply stated, PaaS makes provision for all of the software and hardware tools required for all the stages associated with application development over the internet (web browser).

Hence, the advantage of the Platform as a Service (PaaS) is that, it avails software developers with enough convenience as well as simplicity, service availability, ease of licensing and reduced costs for the development of software applications.

These are the different types of Platform as a Service;

1. Private PaaS.

2. Public PaaS.

3. Open PaaS.

4. Mobile PaaS.

5. Communications PaaS.

6. Hybrid PaaS.

In this scenario, the type of service Don's company signed up for is called Platform as a Service (PaaS).

It is the way to convey a message,an idea,a picture,or speech that is received and understood clearly and correctly by the person for whom it is sent.​

Answers

Answer:

Communication.

Explanation:

Communication can be defined as a process which typically involves the transfer of information from one person (sender) to another (recipient), through the use of semiotics, symbols and signs that are mutually understood by both parties.

In this context, communication is the way to convey a message, an idea, a picture, or speech that is received and understood clearly and correctly by the person for whom it is sent.​

Generally, the linear model of communication comprises of four (4) main components and these are;

1. Sender (S): this is typically the source of information (message) or the originator of a message that is being sent to a receiver. Thus, they are simply the producer of a message.

2. Channel (C): this is the medium used by the sender for the dissemination or transmission of the message to the recipient. For example, telephone, television, radio, newspapers, billboards etc.

3. Message (M): this is the information or data that is being sent to a recipient by a sender. It could be in the form of a video, audio, text message etc.

4. Receiver (R): this is typically the destination of information (message) or the recipient of a message that is being sent from a sender.

An attacker gained remote access to a user's computer by exploiting a vulnerability in a piece of software on the device. The attacker sent data that was able to manipulate the return address that is reserved to store expected data. Which vulnerability exploit resulted from the attacker's actions

Answers

"A Buffer overflow" vulnerability exploit resulted from the attacker's actions.

Whenever a software or an application writes too much data into a buffer, causing neighboring storage regions to have been corrupted as a consequence, this could be determined as Buffer overflow.

⇒ There are two kinds of Buffer overflow attacks such as:

Stack-based - It will become more popular to use such memory, as well as that's only available during implementation of any code.Heap-based - Those attacks seem to be more difficult to execute because they entail overflowing overall storage capacity allotted for a program further than the space needed for something like the program's present activities.

Thus we can say that the correct answer is a Buffer overflow.

Rachel is a junior system administrator for a network with a single Active Directory domain. The network has just expanded to include an additional subnet. Rachel has installed a new server running Windows Server 2016 on the new subnet and configure it as a DHCP server. When she checks the server icon in the DHCP Management console, she notices the server has a down icon. The DHCP server service has started, but the server does not respond to DHCP lease requests. What should Rachel do to solve the problem

Answers

Answer: Ask a member of the Enterprise Admins group to authorize the server.

Explanation:

From the information given, we are informed that Rachel installed a new server running Windows Server 2016 on the new subnet and configure it as a DHCP server but then realizes that the DHCP server service has started, but that the server does not respond to DHCP lease requests.

In this case, the reason for this can be attributed to the fact that the server hasn't been authorized, therefore, she can ask a member of the Enterprise Admins group to authorize the server.

You are concerned about attacks directed at your network firewall. You want to be able to identify and be notified of any attacks. In addition, you want the system to take immediate action to stop or prevent the attack, if possible. Which tool should you use

Answers

Answer:

Intrusion Prevention System (IPS)

Explanation:

Firewall can be defined as a network security device that monitors incoming and outgoing network traffic and decides whether to allow or block specific traffic based on a defined set of security rules.

Simply stated, a firewall is a network security protocol that monitors and controls inbound and outbound traffic based on set aside security rules.

A firewall is used to control access to a computer or network, as it creates a barrier between a computer or a network and the internet in order to protect against unauthorized access.

Basically, it is a network security device or security system pre-installed on most computers to essentially inspect data being transmitted to or from a computer

Thus, the tool you should use is an intrusion prevention system (IPS).
