The two access modes that are used when opening a file for input and output when pickling are rb and wb.

<h3>What is pickling?</h3>

Pickle is generally used in Python to serialize and deserialize a Python object structure. In other words, it is the act of transforming a Python object into a byte stream in order to save it to a file/database, maintain program state across sessions, or transport data over a network. By unpickling the pickled byte stream, the original object hierarchy can be recreated. This entire procedure is comparable to object serialization in Java or .Net.

When a byte stream is unpickled, the pickle module first makes an instance of the original object before populating it with the right data. To accomplish this, the byte stream only carries data relevant to the original object instance.

Suppose end system A wants to send a large file to end system B. At a very high level, describe how end system A creates packets
kvasek [131]

Answer:

When we journey from a particular city to another city and we don’t really know the path then we ask for path and go on that which is just the same thing as packet switching.

Explanation:

Suppose system A intends to send packet to system B the steps and procedures are given below

1. A breakdown of large file into smaller bits of data on system A will first occur.

2.It attach separate headers for every portion of the file so that each portion looks like separate packet.

3.Header file in chunks will contain ip address of the file receiver which here is system B.

4. the Switch system will utilize the IP present in header to decide the link to destination.

Which type of evaluation requires that the program be fully implemented before the evaluation can begin
Drupady [299]

Answer:

Around the world, there exist many programs and interventions developed to improve conditions in local communities. Communities come together to reduce the level of violence that exists, to work for safe, affordable housing for everyone, or to help more students do well in school, to give just a few examples.

But how do we know whether these programs are working? If they are not effective, and even if they are, how can we improve them to make them better for local communities? And finally, how can an organization make intelligent choices about which promising programs are likely to work best in their community?

Over the past years, there has been a growing trend towards the better use of evaluation to understand and improve practice.The systematic use of evaluation has solved many problems and helped countless community-based organizations do what they do better.

Explanation:

<em>Despite an increased understanding of the need for - and the use of - evaluation, however, a basic agreed-upon framework for program evaluation has been lacking. In 1997, scientists at the United States Centers for Disease Control and Prevention (CDC) recognized the need to develop such a framework. As a result of this, the CDC assembled an Evaluation Working Group comprised of experts in the fields of public health and evaluation. Members were asked to develop a framework that summarizes and organizes the basic elements of program evaluation. This Community Tool Box section describes the framework resulting from the Working Group's efforts.</em>

<em>By evaluation, we mean the systematic investigation of the merit, worth, or significance of an object or effort. Evaluation practice has changed dramatically during the past three decades - new methods and approaches have been developed and it is now used for increasingly diverse projects and audiences.</em>

It may apply to any action with the goal of improving outcomes for whole communities, for more specific sectors (e.g., schools, work places), or for sub-groups (e.g., youth, people experiencing violence or HIV/AIDS). This definition is meant to be very broad</em>
