1.3-2 Packet switching versus circuit switching (1). Which of the characteristics below are associated with the technique of packet switching? Please select all correct choices. Note: Each wrong answer carries 33.33% penalty! Select one or more: Reserves resources needed for a call from source to destination. Resources are used on demand, not reserved in advance. Data may be queued before being transmitted due to other user's data that's also queueing for transmission. Frequency Division Multiplexing (FDM) and Time Division Multiplexing (TDM) are two approaches for implementing this technique. Congestion loss and variable end-end delays are possible with this technique. 그 그 This technique is used in the Internet. This technique was the basis for the telephone call switching during the 20th century and into the beginning of this current century.
Two methods for putting this technique into practice are frequency division multiplexing (FDM) and time division multiplexing (TDM).
Multiple data streams can be transmitted over a single channel using TDM. where each signal has a fixed-length time slot for it. In contrast, FDM divides the overall bandwidth into a number of non-overlapping frequency bands, each of which transmits a different signal.
In FDM, separate signals are given their own channels, each of which occupies a different frequency band, and the time is divided into multiple fixed duration slots that are allotted to the signals in a round-robin fashion.
The entire frequency band that is available in TDM is used on a time-sharing basis, whereas in FDM the entire frequency band is divided into multiple channels, each of which is separated by a space.

role-based access control (rbac) uses labels to determine the type and extent of access to a resource and the permission, or security, level granted to each user.
It is false that role-based access control (RBAC ) uses labels to determine the type and extent of access to a resource and the permission, or security, level granted to each user.
RBAC is a technique for controlling network access based on the roles of specific individuals inside an organization.
RBAC guarantees that employees only have access to the information they require to do their duties and stops them from obtaining information that is irrelevant to them.
The rights that are provided to an employee are based on their job within the business, which prevents lower-level employees from accessing sensitive data or carrying out high-level duties.
Roles are based on a number of criteria in the role-based access control data model, including authorization, responsibility, and job competency. As a result, businesses can specify whether a user is an administrator, specialist user, or end user. Additionally, access to computer resources can be restricted to certain capabilities, like the capacity to view and create.

USB 3.0 can plug into a 2.0 port, but will only transmit at the speed of a USB 2.0 true or false
Answer:
true
Explanation:
USB 3.0 backwards is compatible—meaning it's designed to work with older USB versions including USB 2.0 and USB 1.1. You can plug a USB 2.0 device into a USB 3.0 port and it will always work, but it will only run at the speed of the USB 2.0 technology.
A source of emf is connected by wires to a resistor, and electrons flow in the circuit. The wire diameter is the same throughout the circuit. Compared to the drift speed of the electrons before entering the resistor, the drift speed of the electrons after leaving the resistor is.
The drift speed of the electrons after leaving the resistor is same.
What is drift speed?Drift is the sluggish approach to something or anything. Drift velocity is the average speed of charged particles moving through a medium as a result of an electric field.
The average speed at which electrons "drift" in the presence of an electric field is known as drift velocity. The electric current is a result of the drift velocity (or drift speed). Thermal velocity, on the other hand, results in random motion that generates collisions with metal ions.
A change in mass causes an electron moving in a crystal lattice to move similarly to a free electron, as was previously demonstrated. This fact enables us to describe the motion of electrons and holes in a semiconductor device using the classical equations of motion.

This hashing algorithm would work by converting the social security number into an integer and then performing a modulo operation on that number.
what is hashing algorithm
The modulo operation would be performed with a prime number that is larger than 32 such that the number can be divided up into 32 possible values, 0 included. For example, the prime number 41 could be used for this operation. The algorithm would take the individual digits of the social security number, convert them into an integer, and then add them all together. This integer would then be divided by 41 and the remainder would be the hash value. For the example social security number provided (124-34-5438), the algorithm would first convert each number into an integer (1, 2, 4, 3, 4, 5, 4, 3, 8) and add them all together (34). Then, 34 divided by 41 yields a remainder of 8, so the hash value of this social security number would be 8.

[Select] HBO's best response is to always produce a historical drama. [Select ] Showtime's best response is to always produce a romantic comedy. [Select]
The ideal response from HBO is usually to create a historical drama- True. False: If HBO decides to make a romantic comedy, Showtime's best reaction is to do the same. The best way for Showtime to unwind is to create a romantic comedy- True.
The graph's information allows us to determine the profit of HBO and Showtime in light of several scenarios, including:
HBO's income from producing fragrant comedies are $ 19 million and Showtime's are $ 13 million (Showtime)
If Showtime makes a historical drama and HBO does a romantic comedy, the profits are $22 million for HBO and $ 10 million for Showtime, respectively (Showtime)
The revenues from a historical drama produced by HBO and Showtime are $ 25 million (HBO) and $ 8 million (Showtime) (Showtime)
If Showtime produces a romantic comedy and HBO a historical drama, the profits are $30 million for HBO and $14 million for Showtime.
This leads us to the conclusion that:
Because it makes between $ 25 million and $ 30 million per historical drama it produces, HBO's best reaction is usually to do so. On the other hand, it makes between $ 19 and $ 22 million from producing romantic comedies.
When HBO decides to produce a romantic comedy, Showtime's best answer is to produce a historical drama, yet this is untrue because Showtime makes more money producing historical drama than it does when HBO produces a romantic comedy ($10 million against $13 or $14 million).
Given that its profits from producing comedies are between $ 13 and $ 14 million and those from making historical dramas are between $ 10 and $ 8 million, Showtime's best solution is to make comedies.

1. describe how a page fault is handled? 2. what are file attributes? 3. what operations can be performed on files and directories? why are some distinct? 4. compare and contrast sequential to direct access. 5. how is a tree-structured directory different from a acyclic-graph directory?
The way that page fault is handled is by:
Once the virtual address that produced the page fault is determined, the system verifies that the address is genuine and makes sure there are no issues with protection or access. The system checks to verify if a page frame is free if the virtual address is legitimate. The page replacement algorithm is used to remove a page if there are no empty frames.The operations that can be performed on files and directories are:
Open operationWrite operationRead operationRe-position or Seek operationDelete operationTruncate operationClose operationWhat is the compare and contrast sequential to direct access?Sequential access should start at the start and access each element one at a time. Any element may be directly accessed by using its index number or address to find it. There is direct access with arrays. CDs had direct access, but magnetic tape only has sequential access.
Therefore, one can say that direct access eliminates the need to browse the data in order. When data is retrieved sequentially, it is located by starting at one location and moving on to succeeding sites until it is.
