Answer:
Priority programming is a process programming method based on priority. In this technique, the developer chooses the tasks to work according to priority, which is different from other types of programming, for example, a simple round-robin.
On UNIX and many other systems, higher priority values represent lower priority processes. Some of the systems, such as Windows, use the opposite convention: a higher number means a higher priority
<h3>Explanation:
</h3>
Priorities can be dynamic or static. Static priorities are assigned during creation, while dynamic priorities are assigned according to the behavior of the processes while they are in the system. To illustrate, the planner could favor intensive input / output (I / O) tasks, allowing expensive requests to be issued as soon as possible.
Priorities can be defined internally or externally. Internally defined priorities make use of a measurable amount to calculate the priority of a given process. On the contrary, external priorities are defined using criteria beyond the operating system (OS), which may include the importance of the process, the type and sum of the resources used for the use of the computer, user preferences , trade and other factors such as politics etc.
i hope this is right lol
Answer:
The answer to this question as follows:
Explanation:
In option a, When we use fork, a new mechanism, that uses fork() method, which is in the parental process, to replicate all sites. It has been installed in a space-differentiating operating system.
In option b, It is the present system cycle that scan and wait for any of the system processor to be installed.
In option c, The time delay happens when A operates. It is a global that make issues, which are cleared and slowed down when an interrupt happens. In this process, there are not any distractions. It splits into slowly as it heads into the ISR. It helps to understand the code easily.
Answer:
Computer professionals known as software engineers, or programmers use the software development life cycle to create software required for information systems.
Explanation:
Computer professionals are called software engineers and programmers because they develop and program software. Some additional titles for computer professionals are hardware engineers and iOS/Android developers.
Answer:
The <u>ARPANET </u>network became functional in 1969, linking scientific and academic researchers across the United States.
Explanation:
ARPA Net is the network that has become functional in 1969 in united States. The basic purpose of this network is to link all the researchers and scientists across united states. The full form of ARPANet is Advanced Research Project Agency Network.
The importance of this network is increase because small chunks of data that are called packets has been proposed for data transmission in the network. The data is divided into small packets and send it over the network, at destination point these packets are combined together and become orignal information.
Answer:
def transfer(bank, log_in, userA, userB, amount): ''' In this function, you will try to make a transfer between two user accounts. bank is a dictionary where the key is the username and the value is the user's account balance. log_in is a dictionary where the key is the username and the value is the user's log-in status. amount is the amount to be transferred between user accounts (userA and userB). amount is always positive. What you will do: - Deduct the given amount from userA and add it to userB, which makes a transfer. - You should consider some following cases: - userA must be in the bank and his/her log-in status in log_in must be True. - userB must be in log_in, regardless of log-in status. userB can be absent in the bank. - No user can have a negative amount in their account. He/she must have a positive or zero balance. Return True if a transfer is made. For example:
