Chapter 3: Analysis

3.1 User Interface

A user interface is an intersection between user and the OS. While an interface is a set of bids or bill of fare which user can utilize it to pass on with the OS. By and large, there are two cardinal methods allow users to pass on with the operating system. They are CLI and GUI which will be descripted subsequently in this subdivision.

3.1.1 CLI ( Command Line Interface/Command Interpreter )

Main map of the bid translator is to read and put to death the specified bids entered by the user. A batch of bids given at this degree are used to pull strings files: create, delete, move, transcript and more. Now there are besides two methods to in which these bids can be implemented.

Figure 19

The first method shown above ( Figure 19 ) implies that, the bid translator itself has the codification to put to death user entered bids.

Figure 20

While for the 2nd method ( Figure 20 ) whenever bid translator could non understand the bids entered by user in any manner, what will go on, it merely utilize the bid to place a file to be loaded to the chief memory and so executed.

3.1.2 GUI ( Graphical User Interface )

Apart from Command Line Interface, there is besides a 2nd manner which a user can interact with the operating system is through GUI ( Graphical User Interface ) . The Graphical User Interface was developed in early 1981 by Alan Kay, Douglas Engelbart, and a group of other researches at Xerox PARC. In this interface, it provides user with a mouse based window and a bill of fare system as the interface alternatively of merely come ining tiring bids through the Command Line Interface. A Graphical User Interface provides a desktop image where the mouse arrow moves its place on images, or icons, on the screen ( desktop ) that represent plans, files, directories, and system maps harmonizing to how our mouse moves on a mouse tablet. By snaping the mouse button, a mouse arrow can put to death a plan, select, move, create, and cancel a file or directory which is recognized as a booklet

Figure 21 Windows XP

Unlike a Command Line Interface, Graphical User Interface is more suited for a computing machine nonreader user to larn and utilize because there is no demand for users to memorise or to acquire usage with specific bids in order to pass on with the Operating System. Due to the easiness of usage, now a twenty-four hours GUI OS have become the dominant OS which is used by most of the users.

The UI is really of import for any plans created because it will find how easy you can teach the plan to make what you want to. The pick of whether we should utilize a CLI or GUI OS is largely depending on us. Some users may prefer a CLI OS more than a GUI OS because they provides a strong shell interfaces.

3.2 Process Control Management

A procedure is a plan in executing manner. It is said to be in the running province if it is presently in the CPU. A procedure will be in the out of use province if it is waiting for some event to happen. The procedure will so be transportation to a out of use list where all procedure are in asleep manner or inactive, waiting for events that will wake up it. A procedure will be in ready province if it is waiting to come in the CPU. All procedure in ready province will be in a ready list or ready waiting line. The procedure will come in the CPU based on the programming algorithm. A procedure may exchange its province at any minute, and therefore a record is needed to guarantee that all procedure will be able to finish its undertaking. All these information and more are recorded in procedure control block ( PCB ) .

3.2.1 Process Control Block

The PCB is a information construction incorporating of import information about the procedure which includes the below:

The current province of the procedure

Unique designation of the procedure

A arrow to the procedure ‘s parent ( the procedure that created this procedure )

Arrows to the procedure ‘s kid processes ( procedures created by this procedure )

The procedure ‘s precedence

Arrows to turn up the procedure ‘s memory

Arrows to allocated resources

A registry save country

The processor it is running on ( in multiprocessor system )

The PCB is really of import and serves as a shop of information that allows the OS to turn up all critical information about a procedure. When the CPU switches between active procedures, it will mention to the information saved in PCB in order to re-start the procedure the following clip it is in the CPU.

3.2.2 Scheduling Algorithm

Procedures in the ready list or ready waiting line demands to come in into the CPU but the choice of which procedure to come in first is really critical as to avoid famishment. Besides that, all procedure has to be treated reasonably and throughput has to be maximized. This complex job is solved utilizing scheduling algorithm. The scheduling algorithm will find which procedure will come in the CPU first and for how long it will stay in the CPU.

In general, there are two sorts of scheduling algorithms, pre-emptive and nonpreemptive. In pre-emptive programming algorithms, the procedure will be forcefully removed from the CPU upon having a bid from the OS. Examples of pre-emptive programming algorithms are circular redbreast and multilevel feedback waiting line. In nonpreemptive programming algorithms, the procedure will merely go out the CPU upon completion. Examples of nonpreemptive programming algorithms are foremost in first out ( FIFO ) , shortest occupation foremost ( SJF ) and precedence.

Windows XP uses a priority-based, pre-emptive programming algorithm. This algorithm will guarantee that the higher precedence procedure will be executed in the CPU foremost. The procedure will go on to run until it is preempted by a higher precedence procedure, until it finishes, until its clip quantum terminals or until it switches to a block province. When a higher precedence procedure becomes ready while a lower precedence is running in the CPU, the lower precedence procedure will be preempted. All procedures will have a precedence encouragement after a wait event, but processes with a keyboard I/O delay will see a greater encouragement than those in a disc I/O delay

3.3 Deadlock Management

“ A procedure in a concurrent execution system is said to be in a province of dead end ( or deadlocked ) if it is waiting for a peculiar event that will non happen. ” ( Deitel, 1990, p. 155 ) In short, a dead end occurs when a procedure ‘s petition for resources – be it a infinite in the chief memory or information from the waiter – will ne’er be fulfill.

A simple illustration of how deadlock occurs is shown in Figure 22. Process A petitions for Resource 2. While on the other manus, Process B is keeping Resource 2 and is bespeaking for Resource 1 which is being held by Process A. Each procedure is waiting for the resource to be freed and each procedure will non let go of the presently held resource until it acquires the following resource. This round delay will do an indefinite delay and is the chief feature of a dead end system.

Procedure A

Procedure B

Resource 1

Resource 2

Request

Keep

Figure 22 Example of a dead end system

Harmonizing to Havender, there are four conditions which must be in consequence for a dead end to happen. There are

Procedures claim sole control of the resource they require ( common exclusion status ) .

Procedures hold resources already allocated to them while waiting for extra resources ( delay for status ) .

Resource can non be removed from the procedures keeping them until the resources are used to completion ( no pre-emption status ) .

A round concatenation of procedures exists in which each procedure holds one or more resources that are requested by the following procedure in the concatenation ( round delay status ) .

Therefore, the manner to get the better of the dead end system is to use bar, turning away, sensing and recovery method. In dead end bar, the scheme is to take any possibility of a dead end happening. Prevention is a clean solution but lacks in a good resource use system. While being so, it is the most widely used method.

In dead end turning away, the end is to enforce less stiff conditions while seeking to acquire better resource use. Avoidance does non intend to take all possibility of dead end but allows dead end to loom but carefully avoid it whenever a dead end attacks.

In dead end sensing, a dead end is allowed to take topographic point either volitionally or unwillingly. Once the dead end occurs, the system will place which procedure and resource is involved and cleared it from the system.

In dead end recovery, dead ends are cleared from the system, so that the procedure may finish its executing and let go of the resources. This method may non be the best as most of the rose-cheeked procedure will either loss portion of the work if non all of the work antecedently done.

Windows XP applied multilevel feedback waiting line scheduling algorithm to forestall dead end from go oning by dividing the ready waiting line to three separate waiting lines. Each waiting line has its ain programming algorithm with the first two using unit of ammunition redbreast scheduling algorithm with different clip quantum and last waiting line utilizing foremost in first out scheduling algorithm. A new procedure enters into the first ready waiting line and delaies for its bend. When it enters into the CPU, the procedure will have 8 msecs. If it does non finish within the clip quantum, it will be preempted and travel to the 2nd waiting line. In the 2nd waiting line it will wait for its bend to come in into the CPU one time more. Upon come ining the CPU, it will have 16 msecs to finish its undertaking. If it is still non completed after 16 msecs, it will be preempted once more and come in the 3rd waiting line where the procedure will be finish upon come ining the CPU utilizing the first in first out scheduling algorithm. The full procedure is illustrated in Figure 23.

3.4 Memory Management

In most of the modern computing machine, they will hold a memory hierarchy with volatile cache, volatile chief memory ( RAM ) and nonvolatilizable disc shop. Operating system is responsible to organize how these memories are used. The memory director is responsible for pull offing the memory hierarchy. Its importance undertaking includes implement practical memory, copy-on-write memory, big memory support and organize the base for the cache director.

There are two general attacks to the memory direction can be used. The simplest scheme called Swapping. However, Windows XP is utilizing another scheme called Virtual Memory which allows plan to run even they are merely a portion of the plan swapped in the chief memory.

3.4.1 Virtual Memory

Windows XP will utilize the practical memory to compensate when the random entree memory ( RAM ) is insufficiency to run a plan or operation. When a computing machine is short of RAM, practical memory will travel the informations or codification from RAM to a infinite that called paging file. By making this, the RAM will be free up and is able to finish the work.

In the practical memory system, each procedure has its ain practical memory, called an reference infinite. In Windows XP 32-bit edition, the practical reference infinite is 4 Gs ( GB ) and in can be split into two dividers from 2 GB is used by procedure another 2GB is used by system to 3GB for procedure and 1GB for system ( MSDN Library, 2011 ) . In 64-bit Windows XP, each procedure has the practical reference infinite about 7152GB on IA-64 spot system and 8192 GB on x64 system ( Russinovich & A ; Solomon, 2008 ) . All procedure can entree its practical reference infinite, but the address infinite is private and can non be accessed by other procedure, unless it has been shared.

3.4.2 How Windows XP Handles Memory Management

Figure 25 Virtual memory demand for 25 operations selected from an hour-long hint

Operation

Application

System informations

System

Driver

The figure 25 show that, the sum of practical memory use which used by a figure of operation taken from a long-running work load state of affairs on Windows XP. The work load contained office productiveness plan and web browse and the operation involved activity such as get downing up an application, salvaging and publishing paperss, opening and shuting a file or web page. The practical memory shown the available sum of memory that can keep all the codification and informations used in the operation and all the resource that are locked into a computing machine memory. Harmonizing to ( Microsoft, n.d ) the practical memory can be used by the followers:

The infinite taken by application. For the operation that depend about wholly on the system service, such as opening a web page, to significant, as when an application starts and must initialise itself. This can be seldom from different.

The infinite taken by the driver codification. This is comparatively immutable, on history of much of the codification driver is locked in the memory or is in regular usage.

The allocated and mapped informations used by the system. This contains register informations, many system informations construction, and files accessed by runing system.

The infinite used by the system itself. This consists of the infinite used by the shell and all the system ‘s service processes.

3.4.5 Allocating Memory for Application

In the Figure 25, each operation takes from 20 MB to 50 MB of the practical memory. The operating system will administer the physical memory to map this practical memory. The single operation can easy suit in 64 MB of RAM, but if the user would wish to continue from operation to operation, some of the content will be replaced. As Figure 3 shown that, the sum of 256 MB of distinguishable pages were touched. If back-to-back operations overlap to a great extent in the practical memory they touch, the new operation will necessitate a small or no I/O. Switch from one application to other is likely to affect a larger alteration in the contents of the practical space.A

3.4.6 Balancing Memory Resources

There is no exclusive “ memory demand ” for an application or the system. When the physical memory is lacking, the system will pay for the I/O punishments as the user proceed from operation to operation. When physical memory is non sufficient, the system will non necessitate to pay for I/O punishments, because the system has used the memory to prevent it.

The operating system will take which pages to maintain and which to acquire rid of. Thus, the figure of pages in usage entirely does non stand for a step of memory required. The memory director will let the procedure to turn beyond its upper limit when it is paging to a great extent and there is adequate memory. However, when there is no paging and high demand for physical memory on the system, memory director will shrivel a procedure below its working set minimal to do the memory available.

3.4.7 Placement Policy

Windows XP implements a combination of local ( each procedure selects from its ain set of allocated frames ) and planetary replacing policyi??process selects a replacing frame from the set of all framesi?‰ . Common replacing policies include least late used ( LRU ) and first in, foremost out ( FIFO ) . The LRU algorithm requires the practical memory system to track when a page in memory is used. It will replace the procedure that has non been used for a long clip. The FIFO algorithm it removes the page that has been in physical memory for a long prior of clip, even the procedure is in usage.

3.5 Secondary Disk Scheduling Management

3.5.1 Secondary Storage

Secondary storage is a last degree of file system. It is the patterned advance from magnetic tapes to discs. Compared to discs, magnetic tape ‘s entree clip is much slower. Magnetic tapes are normally used to hive away and backup infrequently used informations.

3.5.2 Disk Scheduling

Disk programming is the operation systems which is responsible to utilize the hardware efficiency. There are two standards for disc drivers which is fast entree clip and besides to increase disc bandwidth.

Basically entree clip has two major constituents

Seek Time refers to the clip for the disc arm to travel the caput of the cylinder containing desired sector

Rotational Latency is the extra waiting clip for the disc to revolve to the desired sector of the disc caput

Disk bandwidth is the entire figure of bytes transferred divided by the entire clip between the first petitions for service to the completion of the last transportation.

When a procedure needs an input/output from the disc, system calls are sent to the operating system. If the disc is free, so bespeak will be serviced. Else, the petition will be located on a waiting line.

3.5.3 Disk Scheduling Algorithms

There are 6 types of disc scheduling algorithms which are:

First Come First Serve

Shortest Seek Time First

Scan

C-SCAN

Look

C-LOOK

3.5.3.1 First Come First Serve

FCFS is the simplest disc scheduling algorithm among the others. It is n’t supplying the fastest service. As the petition arrives they are placed on a waiting line and are satisfied in order of reaching.

Figure 26 FCFS disc scheduling

3.5.3.2 Shortest Seek Time First

SSTF prioritise the first petition which is nearest to the current caput place, it minimizes the seek clip. Requests can get at any clip but the petition which located furthest from the caput will necessitate to wait for a long clip before it gets serviced.

Figure 27 SSTF disc scheduling

3.5.3.3 SCAN

The disc starts at one terminal and move towards the other terminal, scanning back and Forth. The caput contraries and moves back. It serves petitions while traveling back. If petition ranges right in forepart of the caput so it will acquire serviced foremost. However if a petition reaches merely after the dorsum of the caput, the petition will necessitate to wait until the arm moves back. SCAN is besides known as the lift syndrome.

Figure 28 Scan disc programming

3.5.3.4 C-SCAN

Figure 29 C-SCAN disc shedulingJust like SCAN disc scheduling algorithm, C-SCAN is a discrepancy. It is a round scan. It starts serving from the caput until it reaches the terminal, so the arm moves back without serving any petitions on waiting line.

3.5.3.5 Expression

The disc arm moves from one terminal to the other merely like SCAN and C-SCAN. Alternatively of traveling to the terminal of the disc like SCAN disc scheduling algorithm, LOOK goes every bit far as the concluding petition.

Queue = 23, 89, 132, 42, 187

There are 200 cylinders numbered from 0 – 199 ; Head starts at 100

Figure 30 LOOK disc sheduling

3.5.3.6 C-LOOK

C-Look disc scheduling algorithm starts from the current caput and moves towards the terminal and Michigans at the last petition without traveling to the terminal of the disc. When contrary back, it does non serve any petitions on waiting line.

Figure 31 C-LOOK disc programming

3.6 Standard Support

Most of the Windows user will jump right past the Help files in Windows 95 and 98, which are due to a Help engine that ‘s highly hard to voyage. In Windows Me and 2000, the HTML-based interface is much easier to utilize, but the online Help file still a user manual that is in a little pieces and necessitate to be update ( Bott et al. , 2001 ) .

In Windows XP, The Help And Support Center in Home and Professional have include tremendous aggregation of resource in every degree of experience. Besides that, Windows XP besides provide excess integrated into the Help And Support Center like ( Bott et al. , 2001 ) :

Linkss to system tools and public-service corporations which includ Disk Defragmenter, System Configuration Utility ( Msconfig ) , Network Diagnostics and Windows Update, all of which run within the Help And Support Center window.

Syntax and usage information for 175 alphabetically command-line options.

Supply the links that can roll up up-to-date information about your system and current constellation, with inside informations about all installed hardware, package, and services.

Able to entree to error logs, position of services and other advanced system information.

Able to entree to Group Policy scenes ( Windows XP Professional merely ) .

Enable links to external information beginnings, such as the Microsoft Knowledge Base and an mixture of Windows-focused newsgroups.

Entree to Remote Assistance, which allows a Windows XP user to inquire a friend for aid ; the more experient user can link straight to the machine sing the job via the Internet or a local country web and do needed fixs or constellation alterations straight.

Decision

Operating system is the bosom of the computing machine system without which the computing machine will merely be a piece of hardware. The operating system is made up of complex algorithms and mathematical computations. Algorithms like priority-based, pre-emptive CPU programming algorithm, multilevel feedback waiting line scheduling algorithm, least late used page replacing algorithm and foremost in first out page replacing algorithm all work closely to guarantee that the user will hold the best experience in utilizing the Windows XP runing system.

Besides that, like a traffic constabulary, OS ensures that all procedures and users in the networked environment do non interfere with one another. OS besides communicates with I/O devices like keyboard, mouse and proctor for the user to interact with the system. With an synergistic and advanced GUI, Windows XP have proved to be a dependable operating system in its clip.
