Advantages And Disadvantages Of Serial Processing Operating System

Advantages And Disadvantages Of Serial Processing Operating System Posted on 7/25/2018 by admin What is serial processing A processing in which one task is completed at a time and all the tasks are run by the processor in a sequence. Finally, raw processing power is not the only constraint on system performance. Two processing cores sharing the same system bus and memory bandwidth limits the real-world performance advantage. If a single core is close to being memory bandwidth.

Advantages And Disadvantages Of Serial Processing Operating System Screen

.Advantages of using Windows:. Ease of use.

Users familiarwith earlier versions of Windows will probably also find the more modernones easy to work with. This is ascribable to everything from thestandardised look and feel of almost all programs written for Windows tothe way the file system has been presented ever since the days of MS-DOS(disk A:, disk C:, etc.). This is one of the main reasons why Windowsusers are often reluctant to switch operating systems. Available software. There isa huge selection of software available for Windows. This is both due to andthe reason for Microsoft's dominance of the world market for PC computeroperating systems and office software. If you're looking for an applicationto suit your business needs, chances are that if it exists there will be aWindows version of it available somewhere.

List Advantages Of Operating Systems

Backwards compatibility. Ifyou're currently using an older version of Windows and need something moreup to date, but you don't want to loose the use of some older programs thatare only available for Windows and are critical to your business needs, thechances are good (although not a certainty) that those programs will alsowork with a newer version of Windows. Support for new hardware.Virtually all hardware manufacturers will offer support for a recent versionof Windows when they go to market with a new product.

Again, Microsoft'sdominance of the software market makes Windows impossible for hardwaremanufacturers to ignore. So, if you run off to a store today any buy somerandom new piece of computer hardware, you'll find that it will probablywork with the latest version of Windows. Plug & Play. As anoperating system for the average home user, Windows still has an edge overthe competition in the area of Plug & Play support for PC hardware. Aslong as the right drivers are installed, Windows will usually do a goodjob at recognising new hardware.

Other operating systems also offer Plug& Play functionality, but to a lesser degree and more frequentlyrequire manual intervention. Games. If you crave thelatest in PC gaming technology, then you need Windows. A plethora ofgaming titles are available for Windows, as well as lots of specialgaming hardware that's supported. Some of the most popular games are alsoavailable for Linux, and even more for the Mac, but there's really nocomparison. It must be said, though, that not all of the old games thatwere written for Windows 95 and 98 will also work with XP. Compatibility with MS drivenwebsites.

After Windows had become the world's most populardesktop operating system, Internet Explorer (IE) became the world's mostpopular web browser soon after Microsoft began bundling itwith Windows 95 in order to squash competition from rival Netscape'sNavigator browser. Since Netscape's demise, Microsoft have introducedmore and more proprietary features into their web servers that can onlybe taken advantage of with Internet Explorer. Obviously, these sites areless accessible with other browsers − sometimes not at all.

This,coupled with the fact that the latest versions of IE are only availablefor Windows, has made Windows the only choice for those who want to takefull advantage of those websites that use Microsoft's technology.Disadvantages of using Windows:. High resource requirements.As opposed to the makers of other operating systems, Microsoft requires itscustomers to invest the most in their computer hardware: a faster processor(the CPU), more internal memory and a larger hard disk. Microsoft have alwaysmaintained that this is due to all the extra functionality that they'veadded, as demanded by their customers. Actually, few people make use of manyof those features, yet everyone is still forced to contend with theadditional overhead that is the result. (Ref: ). Closed Source. Troubleshootingproblems with Windows would be so much easier for users and support personnelif only they knew what was actually going on.

Unfortunately, only Microsofthas full access to its software's source code, and since no log files aregenerated its users are left to try and deduce what causes their problems bytrial and error alone. At best this is time-consuming, while at worst it canmake a program impossible to work with. See also: 'Shared Source'. Poor security. Compared toother operating systems, Microsoft security is weak. According to their owndevelopers, their products 'just aren't engineered for security.' Theresult is that Windows computers are more likely than othersystems to be hijacked and used to distribute everything from spam topornography (Ref: ) to hate mail.

Even worse, any such activity onlypoints to the computer that was compromised: since Windows does not generatelog files, the owner has no way of proving anyone else's involvement.Another aspect of this issue has to do with internal security from anadministrative point of view. Configuring any computer is time-consuming andWindows is certainly no exception. Therefore, it's better if users can beprevented from making changes to certain parts of the system, whether onpurpose or by accident. Unfortunately, only with great difficulty is itpossible to achieve a level of fine-grained administrative control onWindows systems, which is why it is rarely seen outside of largerorganizations. What all this means for businesses is that Windows systemsrequire a lot more time and effort to maintain than other systems. Failureto do so will only result in more lost productivity or worse. Virus susceptibility.

Thissubject is usually regarded as part Microsoft's general problems withsecurity. However, the susceptibility of any of Microsoft's operatingsystems to computer viruses has always been pronounced; nearly all computerviruses target Windows computers and regularly wreak newsworthy havoc.Indeed, if it wasn't for Windows, the multi-million dollar anti-virusindustry as as we know it would be virtually non-existant. Viruses onother platforms, save for perhaps the older Mac operating systems, arestrictly a rarity. What this means for businesses, is that that they haveno choice but to keep investing in anti-virus software for all of theirWindows computers, as well as to keep up with the almost daily release ofMicrosoft security patches. Outrageous license agreements.Most people never bother to read the EULA, or End User License Agreement,that must be agreed to before any Microsoft product − including servicepacks and security updates − can be used or installed. Most peoplesimply regard these screens as an irritant that must be to clicked through inorder to install the product. However, if they did take the trouble to readthe EULA, many would probably be a little more than irritated.

For instance,Microsoft's EULA for Windows XP was radically ammended for people whoinstalled a security update in mid-2002 that fixed an obvious and potentiallydangerous security leak in Windows Media Player. It states explicitly:You agree that in order to protect the integrity of content and softwareprotected by digital rights management ('Secure Content'), Microsoft mayprovide security related updates to the OS Components that will beautomatically downloaded onto your computer. These security related updatesmay disable your ability to copy and/or play Secure Content and use othersoftware on your computer.So, along with a routine security patch, Microsoft also slipped in this newagreement that gives them the right to install any software on your computerthat they see fit − including software that 'may disable your abilityto.

Use other software on your computer'. Basically, this amounts togiving Microsoft 'Administrator' rights on your computer (so much for privacy).No doubt Microsoft would say that this measure is only meant to targetpirated software, but the EULA is vague insofar that it does not exclude thepossibility that software acquired legally from vendors other than Microsoftcan be disabled as well.

In this article, we are going to learn about the different types of operating systems, its advantages and disadvantages.Submitted by, on November 07, 2018There are following types of Operating systems:. Batch Operating System. Time-Sharing Operating System. Distributed Operating System. Network Operating System.

Real-Time Operating System1) Batch Operating SystemThere is no direct interaction of this operating system with the computer.There is an individual operator which takes similar kind of jobs having the same needs and requirements and then group them into different batches. It is the work of the operator to sort the jobs with the same requirements.Advantages:.

Processors of the batch systems are aware of the time duration of the job even when it is present in the queue. Batch systems can be shared by multiple users. There I very less idle time of the batch system.

It enables us to manage the efficiently large load of work.Disadvantages:. It is very difficult to debug the batch systems. It proves to be costly sometimes. If any job fails, then it is difficult to predict the timeExamples:Payrolls Systems, Banks Statement etc. 2) Time-Sharing Operating SystemSome time is given to each task to execute or et implemented.so that each task is able to work smoothly. Each and every user occupies the time of CPU as they use a single system.Thus these systems are also known to be multitasking systems. Hence the task could be undertaking either by a single user or even multiple users.

Quantum is the word used for the time required by each task. After each quantum, the OS switches over to the next task.Advantages:.

Duplication of software is less probable. Each task is given equal importance. The CPU idle time can be decreasedDisadvantages:. Problem of reliability. Care of security and integrity is to be taken of user data and programs. There is a problem in data communicationExamples:Multics, Unix etc. 3) Distributed Operating SystemIndependent systems have their own memory unit and CPU.

These are called as loosely coupled or distributed systems. These systems processors vary in sizes and functions. 4) Network Operating SystemThese systems run on a server.

These systems provide the functionality to manage data, users, applications, security, groups, and also some other networking roles. These allow shared access to networking functions on minor or small private network. All the users who know the configuration, of all the other users in the network, their private or individual connections etc.

And hence these are referred to as tightly coupled systems.Advantages:. The servers are Highly stable and centralized.

Servers handle Security concerns. New technologies and hardware up-gradation can be easily integrated. Server access is possible remotely from various locations and different types of systemsDisadvantages:. Costly servers. Depended on central location. Regular updates and maintenance requiredExamples:MS Windows Server 2003, MS Windows Server 2008, NetWare, BSD etc.

5) Real-Time Operating SystemUsed in real-time systems. The time interval which is needed to process and respond to inputs is very less. This time interval is known as response time.Real-time systems are used when there are very strict time needs like missile systems, robots etc.There are two types of Real-Time Operating System:. Hard Real-Time SystemsFor the applications where time constraints or conditions are very strict and even the smallest or shortest possible delay is not accepted. These systems are mainly built for saving a life like automatic opening parachutes or airbags which are required to be immediately available in case of an accident.
