Answer:
Open systems
Explanation:
Open systems are very different from Open Source applications or software, it should not be confused.
Open systems work with the blend of open software standards, portability, and interoperability. Computer systems that interoperate among multiple standards and vendors to ensure that computer resources (hardware and software) are not allotted to a particular vendor. Such computer systems are considered as open systems.
For instance, computer systems that run a Microsoft Windows OS can be considered as an Open system. This is because of their capability to run different versions of the Microsoft Windows OS on that particular computer system. More clearly, A computer with Windows 10 OS, can be used to install Windows 8 OS without any issue. That same computer system can run the Windows 7 OS. This makes the computer system and open system.
In a ____________________ attack, the attacker sends a large number of connection or information requests to disrupt a target from many locations at the same time.
DDoS - Distributed Denial of Service
Explanation:
In DDoS attack, the attack comes from various system to a particular one by making some internet traffic. This attack is initiated from various compromised devices, sometimes distributed globally through a botnet. It is different from other attacks such as (DoS) Denial of Service attacks, in which it utilizes an unique Internet-connected device ( single network connection) to stream a target with the malicious traffic. So in DDoS, multiple systems are involved in the attack and hence we can conclude that as the answer.__________ involves analyzing a large amount of data to extract knowledge and insight

Which installation changes from the old information system to the new one incrementally, starting with one or a few functional components and then gradually extends the installation to cover the whole new system?
Answer:
Phased installation
Explanation:
The name of this strategy is phased installation. Phased installation (or phased implementation) occurs when an existing system is replaced by a new one. However, unlike most implementations, this takes place in stages. This has several advantages. First, it allows you to test the system. If there is a problem with it, it is easier to revert back to the old strategy. Moreover, if employees need to adopt this new system, it allows them to get used to it slowly while still being able to access the previous one.
Final answer:
Incremental implementation is a method that replaces an old information system with a new one in a gradual manner, beginning with a few components and then extending to the entire system, which is part of the incremental design process.
Explanation:
The installation method where the old information system is replaced by the new one incrementally, starting with one or a few functional components and then gradually extending the installation to encompass the entire new system, is known as incremental implementation. This approach allows for portions of the system to be updated and enhanced piece by piece, providing a controlled transition from old to new systems and minimizing disruptions. It's a part of the overall incremental design process, where design is done in pieces, and each piece can be modified or enhanced as needed to gradually improve the entire system. Throughout the project, as design efforts increase, the necessary infrastructure, including supply chains for components and manufacturing facilities, must be established to support the production and distribution of the newly designed product or system.

Which of the following is not a component of the programming phase of facility construction? deciding what to build examining space, cost, and other criteria designing the facility with architects deciding what events will be held at the facility and addressing capacity and amenities issues deciding the number and location of food and beverage preparation and sales areas
The programming phase focuses on fundamental design and planning aspects of facility construction but does not typically include deciding which events will be held at the facility. It lays out foundational design elements like capacity and amenities, while event scheduling pertains to operational planning.
The component that is not a part of the programming phase in facility construction is 'deciding what events will be held at the facility'. Programming, as a part of the design process, focuses on gathering information about the project, such as site inventory, analysis, and understanding user needs, environmental conditions, and economic considerations. This phase includes activities like deciding what to build, examining space, cost and other criteria, and integrating findings into the design with architects. It specifically deals with the fundamental aspects of designing the facility, ensuring the design maintains a focus on elements like capacity and amenities to meet users' needs. However, decisions related to events pertain to operational planning, which is distinct from the initial construction programming.
Programming provides the critical foundation for later stages such as schematic design, design development, construction documentation, and construction administration. This early stage of planning helps lay out the essential frameworks and supports potential adaptability in design—not detailed operational planning such as event scheduling.

When evaluating portable CD players, you consider price, the sound quality, and ease of using the controls. These are your ______ in the purchased decision process.
Answer:
Hi you haven't provided the options to the question so I will just give the answer in my own words and you can check with the options.
Answer is ALTERNATIVES
When evaluating portable CD players, you consider price, the sound quality, and ease of using the controls. These are your ALTERNATIVES in the purchased decision process
Explanation:
Purchase decision process is the decision making process used by consumers regarding the market transactions before, during and after the purchase of a good or service.
There are five stages involved in purchase decision process which are: need recognition,
Information search, evaluation of alternatives, purchase decision and post purchase behavior.
Evaluation of alternatives: The information search reveals different products for the consumer to evaluate and understand which product would be appropriate, this can also be referred to as the consumer's alternatives.
Therefore, the answer that best suits the question is ALTERNATIVES. When evaluating portable CD players, you consider price, the sound quality, and ease of using the controls. These are your ALTERNATIVES in the purchased decision process
Answer:
They are my "Alternatives" in the purchase decision process
Explanation:
Before customers take the bold step of purchasing goods or paying for services, they usually pass through five stages. These five stages are:
1. The problem recognition stage.
2. The information search stage.
3. Evaluation of alternatives stage.
4. Purchase decision stage.
5. Post- purchase evaluation stage.
This then implies that before a product is finally purchased or before a service is paid for, the process of buying that product/service commences long before the actual acquisition of the service/product.
In the first stage, the consumer understands/recognizes that there is a problem or need that could be met by a product.
In the second stage, after recognition of the need that must be met by a product or service, the consumer then makes moves to search for further information regarding the possible products that could meet this need.
After the consumer has satisfactorily gathered enough information regarding the products that can possibly meet those needs, he/she then starts evaluating those products/service with regards to the belief in the company producing the products, the degree of importance, characteristics and abilities of the commodity, satisfaction, price etc, in order to choose wisely and correctly.
Therefore, if I consider price, sound quality etc when evaluating portable CD player, those things I consider are my alternatives in the purchase decision process.

This criteria can be divided in several categories, such as determinant criteria and evaluative criteria. In this case, the example describes determinant criteria. This is the criteria that is most carefully considered and is directly related to the actual choice that is made.
If you are trying to create a web page for your band and having difficulty creating links to other groups on your page, what is the most likely cause of this problem?
Answer: Malfunctioning of your hypertext program or malfunctions in your hypertext program.
Explanation: Hypertext is text that contains links to other texts. The HyperMedia is a collective term which can include graphics, video, sounds and texts, hence Hypertext.
The Hypertext also be said to be a special type if database system in which objects like Text, pictures, music, programs etc can be linked to each other creatively such that When you select an object, you can see all the other objects that are linked to it and you can move from one object to another regardless of if they have different forms or not. It was invented by Ted Nelson in the 1960s.
According to the question, when you are trying to create a web page for your band and creating links to other groups on your page, you are probably using the hypertext and if you are having problems doing this, then your hypertext linking is malfunctioning.
Anthony is responsible for tuning his organization's intrusion detection system. He notices that the system reports an intrusion alert each time that an administrator connects to a server using Secure Shell (SSH). What type of error is occurring?
Answer:
The correct answer to the following question will be "False-positive error ".
Explanation:
"False positives" indicate the alarm is accurate, so an issue does not necessarily exist. It's is a common concept in medical science, which signifies an error in such a consultation process leading to an incorrect diagnosis of a disease is examined.
In any assessment process, that is an accident where a certain disease that has been screened for is wrongly identified.In protection schemes, still, false positives become popular. For starters, a network intrusion prevention program is searching for abnormalities, including bandwidth differences, interfaces, and channels.So, this type of error is occurring.

Explanation:
The use of simulations has been limited by their ____ a. inability to incorporate situations that a trainee might encounter b. inability to be used on a desktop computer c. need for employees to travel to a central training location d. high development costs
Answer: d
High development costs.
Explanation: Simulation is an approximate imitation of a process or a system that represents it overtime.
In Computer simulation is said to be a process of mathematical modelling that is performed on a computer and is designed to predict the behaviour of or the outcome of a physical system. Computer simulations are now useful tools for the mathematical modeling of many natural systems like in computational physics, astrophysics, climatology, chemistry, biology and manufacturing and also human systems like in economics, psychology, social science, health care and engineering.
" Simulations can be used to explore and gain new insights into new technology and to estimate the performance of systems too complex for analytical solutions and also to do a wide range of other things", but its development cost is very high, Very expensive.
Answer:
D. High development costs
Explanation:
Simulations try to as much as possible imitate the functions or activities of a system or process. They cut across various disciplines such as education, technology, science, management and so on.
One common ground about simulations is that it accrues high development costs. This is due to its closeness to the real-world application. Each block of the real process has to be appropriately simulated to ensure that the same results are obtained.
You receive a suspicious text message from an unknown sender asking you to click on a link to access your current credit score. This is likely an example of ________.
Answer: Phishing
Explanation: A cybercrime in which, a target or targets are contacted by email, telephone or text message by someone acting or posing as a legitimate institution to lure these targets or a target into providing sensitive data such as personally identifiable information, banking and credit card details, and passwords is referred to as Phishing.
The CyberCriminals use these information to access important accounts, steal identities and even money.
Beside email and website phishing, there are phishing methods like 'vishing' (voice phishing), 'smishing' (SMS Phishing).
SOME FEATURES OF PHISHING EMAILS
The Emails are usually Too Good To Be True with a sense of Urgency, telling you to click on the link fast because the offers are limited.
They may tell you that your account will be suspended unless you update your personal details immediately and with attachments you are supposed to click on and from an unusual sender.
Whether it looks like it's from someone you know or don't know if anything seems out of the ordinary, unexpected, out of character or just suspicious please don't click on it the link. It might just be phishing.
Ming's computer crashed suddenly the other day. Ming kept trying the solution that worked last few times it had crashed, even though it is clear that it won't fix his computer now. Ming's failure to solve this problem is most likely due to ______________.

You have two LANs connected via a router. Network 1 has a DHCP server with a single Ethernet interface. Network 2 does not have a DHCP server. You want the hosts on Network 2 to be able to get IP addresses from the DHCP server on Network 1. What should you configure
Answer:
You can connect to the DHCP using manual addressing if there is only one interface for ethernet on Network 1
Explanation:
For a device to connect to the Internet, it requires an IP Address, Subnet Mask, Default Gateway and DNS.
So, to connect to the Internet for Network 2, you need to manually change the IP addressing but leave other settings the same.
Let's say Network 1 is connected to this network
IP Address: 192.168.1.2
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.1
DNS: 192.168.1.1
Then, Network 2 has to be manually configured to
IP Address: 192.168.1.3
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.1
DNS: 192.168.1.1
Every other thing remains the same except a little change to the IP Address
Answer:
Configure a DHCP relay agent on the network 2 router interface and configure the hosts in the network 2 to receive IP address dynamically.
Explanation:
DHCP is an application layer protocol which is used to assign IP addresses and other configuration parameters dynamically.
DHCP relay agents are devices configured to allow networks with no DHCP server access other networks with DHCP for it's services. Without this relay agent, the host can not access the DHCP server in other networks because the router interface is a broadcast and will not broadcast to other interfaces.
Hosts in the network can only send DHCP request broadcast messages if configured for dynamic IP addressing.
You support Richman Investments, a brokerage firm that employs 20 brokers. Each broker has his own client computer, and the firm has a server running Windows Server. All of the client computers are configured identically. Over the past six months, some Windows updates have caused the computers to hang, leaving the brokers without computers to conduct business. How can you ensure that the Windows updates that install on client computers will not cause usability issues?
Answer:
Test Windows update on one computer first.
Explanation:
To ensure that there are no usability issues, the Windows update services should be tested on one computer. This move is to check for any usability issues before the update is deployed to other computers. As soon as the usability is tested and confirmed on one computer after the update, the Windows update services can be used to deploy the updates to other computers.
are the differences between message confidentiality and message integrity? Can you have confidentiality without integrity? Can you have integrity without confidentiality? Justify your answer
Answer:
Check the explanation
Explanation:
The Message confidentiality:
1) If any digital attacker can’t recognize or read the encrypted message then the message is termed as message confidentiality.
2) Making use of encryption and decryption technique to find the confidentiality.
Message Integrity:
1) The message is altered by the receiver and the procedure is called message integrity.
2) In this case initial message is not changed in the transfer point.
3) With the use of summing methods are to find the message integrity.
----------------------------------------------------------------------------------------
No, the two message privacy and integrity are different autonomous processes.
-----------------------------------------------------------------------------------------
Yes, the message integrity without any confidentially. Sometimes hackers finds it possible to alter message in the case of message integrity. Then the confidentiality status of message is damaged.
