Answer: measures how quickly a system performs a process or transaction
Explanation:
Computer performance refers to how well a given computer system performs, which is estimated by its accuracy, efficiency and speed when completing a process or transaction.
A computer performance evaluation will assess a system's resources and outputs to make sure that it´s performing in the best possible way.
Some parameters of performance are latency, speed, throughput, and bandwidth.
Answer:
1. Scanner = reading passports.
2. Barcode reader = automatic stock control.
3. pH sensor = monitor soil in a greenhouse.
4. Microphone = voice recognition.
Explanation:
1. Scanner: Copies paper documents and converts the text and pictures into a computer-readable form. Therefore, it can be used for reading passports.
2. Barcode reader: reads labels containing parallel dark and light lines using laser light or LEDs; the width of each line represents a binary code. Therefore, it is used for automatic stock control.
3. pH sensor: detect changes in acidity levels; data is often in analogue form. Thus, it is typically used to monitor soil in a greenhouse.
4. Microphone: allows audio signals to be converted into electric signals; these can be interpreted by a computer after being converted into digital form. Microphones are used for voice recognition.
Answer:
c. Service oriented architecture (SOA)
Explanation:
In a service oriented architecture (SOA), a component of an application provides services to other components of the application or other applications majorly via a communications protocol over a network. In other words, SOA is a programming or software development technique in which services communicate with each other across different platforms.
One key principle of SOA is to design an application (which in itself is a piece of software with multiple features) that is independent of any product, service, vendor or technology but can be integrated into other applications. SOA makes use of loose coupling - a technique in which a client service remains independent of another service that requires it.
In contrast, a monolithic architecture aims at developing a software that is self-contained, independent and not to be integrated into other applications.
On another hand, Software as a service (SaaS), though a bit similar to SOA, is a model in which an application is made available to customers basically through a network. Users basically access the application via a browser.
Therefore, the best option is
C. Service oriented architecture.
The color sensor if i’m correct
Answer:
At the current rate, surrounded animal species might not be able to stand anthropogenic activities in the nearest future.
Explanation:
<em>Anthropogenic activities are those human activities that causes change in the biophysical environment, ecosystems, biodiversity, and natural resources. It also includes global warming, mass extinction of animals and loss of bio-diversity and other global disasters brought about by human activities</em>.
<em>The main driving force of anthropogenic activities is the pressure brought about by the ever growing human population</em>. The earth is overpopulated by humans, and this pushes man to maximize his environment, even to the detriment of this environment. Animal species are hunted to extinction due to increasing demand for their meat, or ornaments gotten from these animals, or some of their body parts, perceived to hold medicinal power, industrial activities poison the environment and natural resources all around, and some ecology has been destroyed and native species population decimated, just because man felt he had to control his environment, sometimes by introducing foreign species he feels he needs.
If nothing is done to halt the current rate of anthropogenic activities, by controlling human population growth, man might end up occupying the planet all alone by himself with surrounding species utterly destroyed.
