When packets arrive at their destination at different speeds, they sometimes arrive out of order. what does this cause?
a. jitter
b. latency
c. dropped packets
d. error rates

Answers

What cause based on the question is a. Jitter. Jitter is the variation in time between arriving data packets, caused by network congestion, or route changes. The longer the data packet is sent, the more jitter will affect the audio and network quality.

Standard jitter measurement in milliseconds (ms). If you receive a jitter higher than 15-20ms, it can increase latency and result in packet loss, causing a decrease in audio quality. Symptoms of jitter include:

Audio is intermittent Call pending or disconnectedStatic, intermittent, or garbled audio

If the test results show the Jitter rating is higher than 15-20ms, there is most likely a problem with the Internet Service Provider (ISP). If the test cannot be plugged directly into the modem, the ISP should be able to run the test. If they run into a jitter problem in the end, they should be able to solve it.

The given statement that is after developing a model, many case tools can generate program code, which impedes and slows down the implementation process is false.

In computing, code generation is a step in the compiler's workflow that transforms intermediate representations of source code into forms that can be easily executed by the target system, such machine code. Multiple passes are frequently carried out by sophisticated compilers on various intermediate forms.

To begin writing in code, reverse-write the message you wish to communicate. Add a letter and a number between each letter in your original message after that. Your message will appear to everyone else as a collection of random characters and digits.

That question is for my photography class.

Answers

Answer:

72 dpi

Explanation:

72 DPI is standard for social media posts and others. It is not 300 DPI which is standard for print.

The standard dots per inch (DPI) used for blogs, social media, webpages, and emails can vary depending on the specific platform and device.

A common standard for these digital mediums is 72 DPI.

DPI refers to the resolution or sharpness of an image on a digital display. A higher DPI means more dots or pixels per inch, resulting in a clearer and more detailed image. On the other hand, a lower DPI means fewer dots per inch, resulting in a less sharp image.

For digital content displayed on screens, a DPI of 72 is often used because it strikes a balance between image quality and file size. This resolution is considered sufficient for viewing images online without causing excessive loading times or using excessive bandwidth.

It's important to note that when printing physical copies, a higher DPI is generally recommended to achieve better print quality. In print media, resolutions like 300 DPI are commonly used to ensure sharp and detailed prints.
