What happens to operating systems when new hardware upgrades and updates occur?
It improves the computer in all sorts of ways. It can speed up the loading information and find better sources for information.
What does the process of installing an operating system such as fedora rhel involve?
A: Installing Fedora/RHEL is the process of copying operating system files from a CD, DVD, or USB flash drive to hard disk(s) on a system and setting up configuration files so Linux runs properly on the hardware. Several types of installations are possible, including fresh installations, upgrades from older releases of Fedora/RHEL, and dual-boot installations.
What are the advantages and disadvantages of closed operating system?
Advantage: stabilityDisadvantage: cost, and inflexibility (must rely on one vendor for improvements and fixes)A:Limited, but quality support - patches and upgrades are usually released on a infrequent schedule due to the limited number of programmers involved. This is as opposed to an open OS where the code is accessible to everyone and can examine and recommened improvements upon the code.
Objectives of an operating system?
1 Objectives and functions 1.1 OS as a user/computer interface - Usability The reason for an operation system to exist is to make computers more convenient to use. An OS aims to wrap the underneath hardware resources and provides services to end users in a systematic way. These services may be divided into two types: services directly available for end users through all kinds of I/O devices, such as mouse, keyboard, monitor, printer, and so on; and services for application programs, which in turn provides services for end users. If we look on these services as interfaces among different components of a computer system, then the following hierarchical architecture may be obtained: Users Programmer | | | v | | +---------------+ | | | Applications | v | +-------------------------+ | OS designer | Utilities | v | +------------------------------+ | | OS | V +-----------------------------------+ | Hardware | +-----------------------------------+ It is also common to consider Utilities and Applications that are distributed together with an OS parts of the OS, but obviously they are not essential. Utilities are usually called libraries or APIs, providing frequently used functions for the upper-level applications. 1 From the point of view of end users, a computer system consists of a variety of applications they may use. An application is developed by programmers in a programming language. The higher level the utilities are, the easier and more comfortable it is for programmers to code in the corresponding programming language; or the lower, the harder. In an extreme case, the assembly language is almost the same as machine instructions except that mnemonic symbols are used to replace binary strings or opcodes. In this kind of language, programmers have to deal with an overwhelmingly complexity of manipulating computer hardware. On the contrary, in a higher-level language, more user-friendly APIs are available, e.g. opening a file by calling open("C:/filename.txt", "rw") 1.2 OS as resource manager - Efficiency It is not the OS itself but the hardware that makes all kinds of services possible and available to application programs. An OS merely exploits the hardware to provide easily accessible interfaces. Exploitation means management upon the hardware resources, and thus also imposes control upon or manages the entities that use the services so that the resources are used efficiently. In the classes later on, we will discuss this aspect, including process scheduling, memory management, I/O device management, etc. One thing worth mentioning here is that, different from other control systems where the controlling facility, the controller, is distinct and external to the controlled parts, the OS has to depend on the hardware resources it manages to work. +-------------------+ +------------+ | | | | | Controlled | | Controller |-------->| components | | | | | +------------+ +-------------------+ As we know, an OS is in nature a program, consisting instructions, thus it also needs CPU to execute instructions so as to function as a controller, and main memory to hold instructions for CPU to fetch. At the same time, the OS has to be able to relinquish and regain later the control of CPU so that other programs can get chance to run but still under the control of the OS (An analogy to this is that an administrator of an apartment building might live in the same building himself). By utilizing the facilities provided by hardware, the OS may schedule different processes to run at different moments and exchange the instructions and data of programs between external storage devices, like hard disks, and main memory. These topics will be covered as the course proceeds. 2 1.3 Evolution of OS - Maintainability It does not suffice to simply consider an operating system an unvariable unit. An OS may evolve while time elapses due to the following reasons: • hardware upgrades or new types of hardware: With hardware technologies development, the OS also needs to upgrade so as to utilize the new mechanisms introduced by new hardware. For example, Pentium IV extended instruction set of Pentium III for multimedia applications and internet transmission. An OS designed for the previous versions of Intel x86 series will have to be upgraded to be able to accommodate these new instructions. • new services: An OS may also expand to include more services in response to user demand. • fixes: No software is perfect, and any program may contain more or less bugs or defects, thus fixes should be made from time to time. Microsoft Windows is a vivid example of this kind. These situations all require OS designers to build an OS in the way that the system can be maintained and upgraded easily. All the common software design techniques may be applied to an OS, such as modularization. With modularization, the OS is split into multiple modules with clearly defined interfaces between them. Thus, as long as the interfaces are left untouched, each single module may be upgraded independently.
What is the Apple Education Licensing Program?

If you upgrade your iTunes does your ipod get upgraded as well?
No, the iTunes upgrades and the iPod upgrades are completely different, because the operating systems are different.
