Answer 1:
a) Mainframe or minicomputer systems: The resources to be managed here are CPU resources, memory, network bandwidth and storage.
b) Workstations connected to servers: CPU resources and memory resources are to be managed.
c) Handheld computers: Here the resources to be managed are power consumption, memory resources.
Answer 2:
A network computer mainly depends on a centralized computer for most of its services, so the operating system here is minimal, whereas a personal computer has a capability of providing all the required services in a standalone way without depending on a centralized manner and are easy to fix during occurrence of any break or issues.

A user can create and manage processes by using command interpreter and can also determine the ways by which they communicate.
As user level program can access all of this functionality using the system calls, so user can develop a new command-line interpreter
Answer 10:
The two models for Inter Process Communication are:
i) Shared-memory model:
Strength:
1. Shared memory communication is faster compared to message passing model when the processes are present on the same machine.
Weakness:
1. Different processes should ensure that they are not writing simultaneously to the same location.
2. Memory protection and synchronization problems need to be addressed by the processes that communicate using shared memory.
3. Distributed systems contain no shared memory, and thus cannot use this method. ii) Message-passing model:
Strength:

1. Inter Process Communication with message passing requires less synchronization than shared memory.
2. Message-passing model is easier to implement compared to shared memory model
Weakness:
1. Time involved in connection setup for message passing is more than shared memory.

Trap is a synchronous interrupt caused by an exceptional condition. Like invalid memory access. A trap usually results in a switch to kernel mode, wherein the operating system performs some action before returning control to the originating process 3. How can multiprogramming
This causes some issues in that the data could be replicated or stale. Pass By Reference: References the address or location in memory where the data is associated with the argument. Changes made in the subprogram will be made to the data in the calling program as well. Potential Security Disadvantage:
1. Give an example in which the operating system would use a bitmap to manage resource. Answer: Windows, Android like operating systems uses bitmap to manage resources. 2.
The most Common programming paradigm in such machines is message passing. Each node is allocated a small part of the overall problem and they communicate through coordinated message passing. Message Passing Interface (MPI) implementations provide scalability and portability without
I have been asked to use Ubuntu? One comparison between windows and linux is that Linux is a lot freer than windows because windows are restricted. Another comparison is windows are a lot safer because if something breaks you get paid support whereas on Linux you do not have any support. My experience with Linux is not much as I am entirely a windows user.
Situations where access to slwga dll is denied or slwga.dll is not found are common and so are other issues pertaining to faulty download of removewat, Window not genuine, application error on your Windows 7 computer, so the best approach is to download slwga.dll fixer. Title: How to fix slwga.dll missing or not found errors There has not been assigned a security rating to slwga-dll as of yet. The process concerning the file is not considered to be CPU intensive however; it is important to note that executing multiple processes simultaneously might hold an adverse impact on the overall performance of the computer.
Network Monitoring Management I definitely feel that Linux and Windows machines provide very different sets of traits that work better for different things. Linux is clearly the more easily secured server as it allows a lot more granular control of every piece of the operating system and the data that is housed there. Also, being completely open source, it allows for a lot more options for software as well as control over every aspect of the system. Windows, on the other hand, has what I feel is a lot more developed approach to managing users, groups, and machines.
Keyword: 0x80073712 Meta: To Title: Solving the Error 0x80073712 A computer is a delicate machine. It needs an error-free operating system to do its role properly. Errors like 0x80073712 can make it very difficult for any user to get desired results.

User authentication in Ubuntu 15.04 systems in an AD environment All HACKD, LLC systems are supposed to be connected to the Microsoft Active Directory domain. However, after implementing Ubuntu 15.04 in the systems that were running on Windows XP, there is a need to ensure interoperability by allowing Ubuntu users to join the AD domain using their credentials. In such instances, the Samba software suite is used to provide AD connectivity and provide stable, secure and fast file sharing and print services to all clients using the SMB/CIFS protocol. In this case, Samba is a critical component for integrating Linux clients in a Windows environment (Samba.org, 2015).
This can help delete all the malware or malicious content on the computer’s system. This can be the only way to save a computer at times, for example if the memory storage has been filled up with worms that keep copying themselves until the system stops responding. If this is the case then deleting everything can be the easiest way to stop. Other times, the malware is not visible to the user allowing it to travel through the system’s hard drive and damage the files. It can also be disguised as useful files.

If there are so many programs, and the resources are limited, this software called (kernel) also decides when and how long a program should run. It is also called scheduling. It might be very complex to access the hardware directly, since there’re so many different hardware designs for the same type of components. Usually kernels implement somehow level of hardware abstraction to hide the underlying complexity from applications and provide a uniform interface. This also helps application developers to develop
Throughout the night, Mary dreamt of Bill . Her mind raced through memories from the first time their eyes met, how those sweet blue eyes sparkled when he laughed, and how they were in love and drifted apart. She also remembered 4 years ago, when she had seen him while away on business in Orlando, Florida. She thought it had been destiny at the time, seeing each other thousands of miles away from their original homes and being in the same hotel.
1.3 explain how to use resources effectively and efficiently Without effective resources an organisation wouldn’t be able to do the job effectively for example, in my organisation we need to have care assistance to care for every individual which in turn need to be trained to do the job correctly, if we didn’t have a resource in place to cover the training needs we wouldn’t be able to function and care for our service users, this also means we need to have a budget of what we can spend on training, staff are also an important resource as we need to make sure we have enough employees to cover each shifts. There are many ways to use resources efficiently and to minimise and adverse impact on the environment. These include how we organise work activities and the use of resources efficiently understanding their impact on the environment, and finding ways to reduce their negative, and increase their positive impact. For example, by being mindful of waste and extravagance by recycling waste materials, by reusing packaging materials, by using double-sided printing
