而在帧长满足发送 时间大于延迟的两倍时,效率将会高于 50%。 现在发送速率为 4Mb/s,发送一位需要 0.25。 只有在帧长不小于 160kb时,停等协议的效率才会至少达到50%。相关知识点: 试题来源: 解析 当发送一帧的时间等于信道的传播延迟的 2 倍时,信道的利用率为 50% 反馈 收藏 ...
What is a CD? A certificate of deposit, or CD, is a type of savings account with a fixed interest rate that’s usually higher than the rate for a regular savings account. A CD also has a fixed term length and a fixed withdrawal date, known as the maturity date. You lock funds in...
Number of interfaces on the card For a line card with different types of interfaces, this field stands for the number of downlink interfaces. It has two digits. The first digit is 0 if the card has fewer than 10 interfaces. D Interface rate G: GE interface X: 10GE interface Y: 25...
On the other hand, if your information is reported right after you make a credit card payment, it shows that you’re using a smaller percentage of your line, which would make your score a bit higher. Each score is based on the information from a credit report. So if you’re looking ...

Bit RateHome Glossary SHARE The number of bits per second that can be transmitted along a digital network. Bitrate, as the name implies, describes the rate at which bits are transferred from one location to another. It measures how much data is transmitted in a given amount of time. ...
random. RAM is organized and controlled in a way that enables data to be stored and retrieved directly to and from specific locations. Other types of storage -- such as an HDD or CD-ROM -- can also be accessed directly and randomly, but the term random access isn't used to describe ...
of time. The CD format consists of 44,100 measurements of the waveform's amplitude per second, so is said to have a sample rate or sampling frequency (fs) of 44.1kHz. This is important, because the Nyquist Theorem states that the high-frequency limit of a PCM digital audio system is ...
The idea of throughput, also known as the flow rate, is part of the theory of constraints in business management. The guiding ideology of this theory is that a chain is only as strong as its weakest link. The goal for business managers is to find ways to minimize how the weakest links ...
A CD is a type of bank account, which means it is covered by the FDIC. If your bank isn't able to return the money you've deposited, the FDIC will reimburse you for up to $250,000. CDs also offer certainty. Your interest rate is locked in when you open the account. If market ...
