The User Side And Server Side Factors Computer Science Essay
The User facial expression And Server Side Factors Computer Science EssayIn this report, I forget describe and explain about social functionr side and waiter side fixings that screwing influence the exploit of a electronic net profitsite and assign furcateicular waiter side capabilities with consideration for limitation of equipment and softw be node may be utilise to browse the website.User side component partHardw be The run of calculator ashes fundament influence the performance of the website. If the computer system is boring so the user leave alone underwrite a long time to load full website. The quicken of computer depends on speed of RAM, ROM and mainframe.Ram is plugged into RAM slots on the motherboard. It is utilize to storage data while Pc is on. It is volatile and temporary. in that location ar some(prenominal) types of RAM kinds. Examples be SDR RAM, DDR R AM, DDR2 RAM fixed storage is dissimilar to Ram. It already is designed and marryed with the motherboard. So the users dont worry to ascribe the Rom. Rom is only enabled to read data. It is permanent and non volatile.CPU is the most fundamental comp hotshotnt of computer system. It is located in CPU socket on the motherboard. It is utilise to processing data and programs. CPU read directives from RAM and realizes those directives. Computers processing speed depends on speed of CPU, unless it as well as depends on other systems. CPU processes data and programs in 4 steps. at that place atomic number 18 fetch, decode, execute, and write back.And one more important that the user must in allow to relate to meshing is modem. Modem is the oldest inter confederation gismos. It is enabling communication over conventional telephone system. The call of modem is coming from modulator and demodulator. It uses a variety of technologies to assist and improve their communication. All modems admit offer asynchronous communication (which dont lease a common clock t o occur between both devices) and synchronous communication (which is a incessant timed transmission). Modem can not affect to computer speed but it affects to profit speed.Internet fraternity speed It also is an important part that can influence the performance of website. Even the users have a nice computer that has precise devalued speed but they have slow internet speed, they also must take long time to fit and browse the website. The user also must to choose the ISP (internet service provider) that will provide the internet serve for them. Broadband is a vertical mentation for the users because it is debaseder than Dial-up connection.Modem Modem is also important part of internet connection. The users look at it to connect to internet. Modem is the oldest interconnection devices. It is enabling communication over conventional telephone system. The destination of modem is coming from modulator and demodulator. It uses a variety of technologies to assist and improve their communication. All modems can offer asynchronous communication (which dont require a common clock to occur between two devices) and synchronous communication (which is a persisting timed transmission)computer virus is softw be of computer. It occurs when rogue code has entered the computer system. Virus hides itself inside ordinary executable code and makes damage to data, computer system or serve. Actually there are over 20000 viruses in the world. It affects the speed of computers operation and slows down the internet connection speed.Software The users also need to install some software that can make the users easier and faster to connect to internet and browse the website. Examples are Firefox, internet explorer and flash player. Firefox and internet explorer are website web browser that are used to browse the website. cede I think the user should use Firefox because it is better than internet explorer. Firefox provides fast browsing speed, replete(p) security and man y features. And flash player is act software that is necessary for browsing the website. It boosters the web browser easier and faster freight tv set or flash on the website.Server side agentive roleHardware Like the user side factor, innkeeper side factor also require good speed of RAM and CPU. precisely legion provides internet services to the users, so RAM and CPU of server should be very fast. They involve to the server speed.Server speedBandwidth bandwidth is the capacity that a network connection can conduct at one time. It determines how some(prenominal) traffic can be handled by the web server and how a lot material is able to be downloaded at any one time. It can be thought of as a pipe from the web server to the users.Server operating systems It is network operation system software that is used to run computer system. For example is window server 2003. It is the current server version of Windows and Window XP is the workstation version. Window server 2003 is simi lar in demeanor to window NT4.0. There are many version of Window server 2003 which are meshwork edition, Standard edition, Enterprise edition, and Data centre edition. The different editions of window server 2003 support various hardware platforms and server role. They provide a variety of service which enables the users to interact with other users, system, and application. There are many services that are provided in window server 2003. But in this task I will explain veritable(prenominal) services that provided by a window server 2003 directory service.Security There are many risks for a website. They may be virus, Trojan, hacker, spyware. They can steals customers details and use them for fraud. The server should have security software to protect the system such(prenominal) as firewall, Norton internet security. Security also is the biggest worry for commercial website because they save all the details and information of customers that could be stolen. So the server should have a good security to protect them.Port available it is device that is used to transfer data between a computer back-to-back port and an Ethernet local area network. It can be used with all types of serial devices and peripherals. It is possible to use Ethernet in place of serial cables, minimizing workstation welter and also allowing serial devices to be placed far away from the computers with which they are used.The other factors that can influence the performance of websiteWeb browser compatibilityThe website will be browsed by web browser so web browser can affect to the website. The web browse should have all features which help the users to loading the website easier and faster such as flash player. Also web browser should have all compatibility that is needed for a website. For examples are see the website with difference font size, colour, etcImage On the website, the type may be a graphic hyperlink that is used to link to other page of website. There are 2 types of im age that can be used o website. They are electronic image image and vector image.bitmap image is make up of pixels in a grid. Bitmap format is really gentle to use for photos. It is fast to display because the monitor is already just a grid of colour dots, so to display them, the users are just changing the colour of the dots that are already there. But if the users want to stretch a bitmap, they just make all those dots in the photo bigger than the dots on their screen and the photos will be fuzzy. In general, bitmap format is ok for drawings, great for photos and best for the web. But it is hard to stretch, hard to convert to vector. Bitmap image is the archive that has ending .bmp .jpeg, .jpg, .png, .psd, etc And some software to edit bitmap image are Microsoft Paint, Adobe Photoshop, Corel Photo-Paint, Corel Paint Shop Pro, etcVector image is difference to bitmap image. It has a lot of virtues. It is made up of many individual, scalable objects. These objects are defined by mathematical equations rather than pixels, so it always render at the highest quality. These objects may consist of lines, curves, and shapes with editable attributes such as colour, fill, and outline. An object can be modified not only by changing its attributes. Vector image has many advantages such as be stretched to various sizes without losing quality. But it still has some disadvantage such as unsuitable for producing photo-realistic imagery. In general, vector format is great for drawings, lite to stretch, easy to convert to bitmap but it is bad for photos and the web. Vector image is the file that has ending .svg, .wmf, etc And some software to edit Vector image are adobe Illustrator, Corel draw, Xara Xtreme, Serif DrawPlus, etcSound Sound travels in waves. These are ceaseless and are called latitude. The digital go bad wave samples at regular intervals with gaps so small the user ears can not perceive them. There are many types of secure file which are mp3 or wav.Mp3 I t is the good sound file. It is a compressed file and is good for internet connection. It does not require much shop. It does take too long to download and retain good quality. Finally, the mp3 file has a low sample rate and therefore produces a smaller file size. It is better than other sound file such as wav.Wav It has a high sample rate which means the sound quality is closest to that produced by the actual instruments but it is a comparatively large file. Because it is a large file so it requires much stock and the user take too long to download it. It is not good for internet users.Video and animation files Video and animation files produce very large file sizes which require much memory. So they can seriously affect the speed of website. It require long time to download and control a large proportion of bandwidth for duration download even the user use a high quality internet connection. It takes a large proportion of website space and make the website slower. There are man y types of moving picture and animation files which are followingMp4 It is a container format which allows a combining of audio recording, video, subtitles and still images to be held in the one single file. It also allows for innovational content such as 3D graphics, menus and user interactivity. It can be use by many different multimedia. It has very good quality. It also allows for stream via the internet which means the user can watch it online.AVI It is audio video interleave file. It is a video file that conforms to the Microsoft Windows Resource raillery File Format (RIFF) specification. It is a large file and takes memory homegrown to Microsoft windows. It requires a special player that may be included with the Web browser but most of PCs can play it.WMV It is window media video file which is preferred format for windows. It is originally designed for internet streaming applications. It can be streaming and possible to use less memory faster download.Internet connectio n speedThe speed of the users internet connection can decide how fast the web page is loaded. There are many types of internet connection which areBroadband It is a network that uses a medium that can carry multiple signals simultaneously using technique called multiplexing. The most common example for broadband communications is the typical cable television network which transmits the signals corresponding to dozen if TV take over one cable. Finally, broadband network provide very fast internet speed. It is very good for internet users.Dial-up It is the traditional method of connection and remained popular for many years. It has an average speed of 56 Kbps. It uses the existing analogue telephone lines.ISDN It stands for Integrated Services Digital Network. It is a dial-up communications services that uses standard telephone lines to provide high speed digital communication. The two most common ISDN services are Basic Rate larboard and Primary Rate Interface. It could reach speed s of 128 KBps.
