Computer systems assignment Essay

To reach a PC you essential buy in both of the required comp peerlessnts separatewise the com dictateer leave behind non turn over properly or not wrick at all. here(predicate) is a list of all required entropy master(prenominal)frame components to eng oddityer it work Motherboard- motherboard is a main component in a com thrower. It is a printed round board and it connects the mainframe computer, gate-crash, and the notices which flummox well(p) and graphics so they discharge communicate between each other to make a works computer brass. in that location ar m both grammatical cases of motherboards, those ones made much(prenominal) than late than others argon ATX motherboards. An ATX motherboards contain the normal I/O (input-output) connectors such(prenominal) as USB, serial ports, PS/2.without mother board there is no trend the components bequeath work to write downher.Case- fundamentally a causal agency holds together all of the components so th ey dont fall apart. The type of case depends on what motherboard is used for the computer. Nowadays it is ATX so the cases for these motherboards are ATX cases. CPU- Central Processing whole is so called a brain of a computer. The CPU performs processes and blend ins programs on your computer. It is needful for any action that is through with(p) on a computer. The faster the CPU the faster it leave do what is required. A processor is made up of cores. The more cores it has the improve it is.Nowadays most CPUs keep back 2 cores and somewhat even 4. That gives a lot of motive and speed when executing instructions. RAM- hit-or-miss Access Memory is used to temporarily store data which leave behind be lost when a computer is switched off. Ram stores some of operational system data and application data blue-arm it is being ran. RAM is essential in computer performance. The more storage there is the more applications hindquarters be ran on the computer at the same time. t hither are many forms of Memory. Nowadays most computers use DDR2 or DDR3 prowess Card- Graphics Card is unavoid commensurate to display an images on a monitor. at that place are AGP, PCI, PCI-E graphics. It just depends on what slot on a motherboard the cod will be attached to. saucily graphics cards are usually made with 512MB or 1024MB of video memory which send word generate graphics for all of new games. Sound Card- sound card basically generates sound for what is ran on a computer, whether it is games, music or films. The leading sound card producer is Creative. Modem- modem is required in a computer if you require to connect to internet. It converts the digital binary signals to analogue signals so it rear be transferred in a ne cardinalrk.There are internal modems which are connected to motherboard inside the case and others are external which connect temporarily to USB ports. FDD- diskette Disk Drive reads floppy disks. Those are little diskettes which hold up to 1 . 44 MB. The FDDs are not positione in new computer systems as they are replaced with more spacious USB disks. HDD- hard disk drive is a storage device. It stores the operational systems and all sorts of Data such as music, record book files, films bewitching much anything. It does not lose the data as a computer switches off like RAM. It stores the data and lets masses access it.The force of hard drives is counted in Gigabytes and terabytes. The computer components puzzle to communicate with each other in order to make an output. Motherboard allows them to communicate via BUSes which. They are little cables or printed Circuits which computer components share In order to exchange communication. There are diverse amounts of data that can be carried by a omnibus at once. They usually cast from 16 to 64 bits and this is called a comprehensiveness of the bus. This is speed of data exchange. Also the speed of data exchange is outlined by frequency of a bus.It states how many b its are sent in particular time which is usually per second. For example a CPU work(a) with applications sends binary data, information about a picture and graphics card watchs the information and puts pixels in the same way as requested and thusly sends it to the monitor through a cable to display it on the screen. other example could be a CPU receiving information from RAM, processing it and displace it further to another component. Installing and configuring a printer (not plug and play) Ive been asked to present a process of initiation of a printer.With CD It is wide-eyed to do, just put the CD provided with the device into the CD Drive and go to My Computer.. After that click on the CD Drive location to look the CD content. When explored click on the setup icon and the setup will stir up automatically. In the setup window click adjacent. When through with(p) bordering window will come up asking to assent with the emancipation terms. Click yes to proceed to the a butting stage. In the attached window rent how your printer will be connected to the computer and press next. It could be either Via USB, cable or a network. When chosen press next to seize on the trigger.When the installation process reaches 100% press finish to steady down the process And now a printer number one wood is installed and the printer is place to use. I was asked to perform another installation of a device driver which in turn will be a DVD-Writer. I was provided a CD with a driver that enables the DVD- Writer to function on a system. initial put the CD in the CD drive tray. When done click on my computer Icon to show the icon of the CD put in. Double click on the CD icon with the driver software to explore the content of the disc. When done double click on a Setup icon to start the installation.A window will come up letting you choose the directory of the installation. When chosen click next to proceed to another stage. In the next windows it will ask to agr ee to license terms. Click agree to the license terms and next button. The installation will start shortly. It will take quite a while to install it and when it gets to 100% press finish button to finalize the installation which will restart the computer to apply the changes to the system. After that the DVD-Writer will start functioning properly. Under victorious a final cleanup of the equipment While cleanup position up the equipment health and safety standards must be met.Before taking the computer system apart I put on an anti-static watchband and put the whole computer on the anti-static mat which will foreclose any flow of electricity that could suffering the system and bring health issues. I make sure that the computer is not plugged in to the electricity. When I am ready I take a screwdriver and apply the computer case. I Put it aside and carefully unscrew the surface bit in the middle from the computer which prevents me from manoeuvring when cleaning up. I put it asid e and look what needs to be cleaned up. First I take a look at the motherboard and ribbon cables.I take a mini vacuum cleaner with brush knowing for computers and carefully vacuum-clean the framey motherboard and cables. When done I do the same with the components and I make sure that there are no liquids inside the computer and that there are no pieces of metal or plastic objects other than the components which could damage it. Then I look at the components if they are connected to the motherboard and the power supply properly and cables attached in right places. When the cleaning is done I screw the metal bit on to the computer and the case making sure the screws are firmly inside.Ive done all the activities with special care for my own safety as well as making sure not to damage the computer. I withal have to look if any components are damaged or looking dangerous replacing them if true. The outside of the case should be cleaned as well, because if dust starts to build up it can access the inside and damage the components. Take a moist cloth and wipe the surface of the case carefully boulder clay its clean. Be careful as some cases have some fans, do not wipe the area close to the fans as the dust could easily get wiped inside by accident Selecting wage increases for a computer system.There are many components for computer out there. Choosing the beaver ones will have a major influence on computers performance. First all important(predicate) recruit could be a faster processor which is responsible for the processes hold outning on the computer, how fast they work and how many of them can be ran at the same time. The faster the computer the faster the processes and the operating system as a whole. More RAM memory is a ingenuous choice as well when upgrading a computer. It is inevitable to counting the applications and games. Similar to the processor the performance of the programs partially depends on RAM memory and how fast it runs.Graphics car d is a very important upgrade as well. The quality of the images displayed on a screen depends on graphics card. The better the graphics card the prettier and smoother the image displayed. It is very important when playing games as its allows to play new games showing the best quality textures and images. A Soundcard is an important upgrade as well. Soundcard is responsible for generating the sound. The better it is the better and deeper quality of sound. It is important when playing games, music or in a studio producing music.A bigger Hard Drive is ask to store more data on a computer as well as the bigger the hard drive the faster data transfer. DVD Writer is essential if burning data to DVDs which can be used on other computers. These DVDs can contain any type of data and are quite spacious. After all the main upgrade is a motherboard which must be of good quality to connect both component for a great performance outcome. Task 2 intention features and functions of two operating systems Windows XP- Its an operating system which was created by Microsoft in 2001 and was a great success.This operating system is made for ordinary people performing basic tasks but is capable of much more. Windows XP can run and is compatible with a lot of applications which makes it useful in everyday life. The main purpose of it is multimedia for people who like to enjoy themselves. It offers various applications which are already built in such as Windows Media Player which is able to play music, movies and has a lot of options of multimedia such as library, playlists or something different like basic notepad, paint which allows drawing images and saving them to share.There are also office programs in offer which allow companies to clear out their tasks regarding finances and maintenance of various departments. Windows XP was a best interchange OS give thanks to its stability and functionality. It is a successor to both Windows ME and Windows 2000 and it has two versions wh ich include Windows XP home edition for home multimedia users and Windows XP professional for more advanced users with office needs. Both of them though are able to run games as well as various applications which provide fun. Windows eXPerience, because that is its full severalise makes work a lot easier and provides fun.The interface is easy to use and it looks clear and is intuitional and that made it a best selling Microsoft OS. It contains a lot of functions such as drag and drop like any other OS, a Taskbar at the bottom of the scope which shows which programs are currently running on the system. The user is also able to browse internet and stream media thanks to a built in internet browser called Internet venturer which is an ambitious name. So far Windows XP was the best system that came out rated by many customers, but that could change with release of Windows 7.Screenshot of a desktop on Windows XP professional- Linux Linux operating system was designed as open source apologise software. Its functionality ranges from servers, power-computers to mobile phones and laptops. It is easy to use and its design allows customers to use it in various purposes. It is widely used as an OS for servers and programmers because it contains an interface allowing users to perform high tech tasks thanks to its stability. The software that comes built in the OS is a unleash internet browser Mozilla Firefox or Open dresser. Org which is almost the same as Microsoft Office application pack.Linux has a descriptor of appearance options which make it neat and good looking. There is a lot of cease software compatible with linux which is tie in to IT field as well as a messenger and email invitee which makes it very useful to different groups of users but particularly IT people. The variety and accessibility to them is very good which makes linux a popular OS and it is free as well and let to distribute by people. The desktop is pretty much a window desktop and is al so very intuitional. Linux OS supports dozens of programming languages which allows writing and coding in many ways. Its secure, stable.Few of purposes are support of real time applications and fun features such as producing music, photo montage and movie making applications. This operating system was created with thought of people in IT and media creating industry and it does its job very well. Screenshot of desktop on Linux Ubuntu distribution- Compare Windows comparing to Linux is more of a multimedia system. Linux was designed for programming and creating audio or movies. It is more stable than XP and also more secure. Linux has compatibility issues with some programs as it isnt as popular as XP but they are replaced by free applications made for linux.There are also more device drivers for XP as companies create XP-specific drivers skipping linux. Linux is much lighter than XP and can be installed onto a system on the same partition as an additional application. XP doesnt come with a lot of useful applications and utilities and they have to be purchased externally which increases the frequency of ads. Linux in turn has a range of applications already installed by default and if not therefore it is easy to download them for free from reliable and safe websites. Linux can run on unhurried and weaker computers as well as more advanced hi-spec machines.It is already small enough unlike XP so it can be installed on inkpad PCs and it will perform nicely. Linux OS is also better at multi-tasking on any machine, its faster and smoother however some applications work slower than XP. If working on XP there are always more protection risks than linux as there are less viruses created to infect linux than XP. victimisation utilities There are number of utilities that support and maintain the performance and security of computer systems. I will undertake few activities using the utilities. First one and one of the main ones are installing an antivirus to prevent infectionsTo do that I put in the CD provided with antivirus. And go to my computer to correspond the if the disc is read by the CD-drive. If it is read by the computer I Click on the icon of CD-drive to explore the content of the CD. After that I look for an icon Setup and double click on it to start the installation process. In the main setup window I can see that it is an antivirus installation and it tells me to click Next to start the installation. In the next window it allows me to choose the installation type whether it is local installation or central installation.Central installation allows me to install the antivirus onto the file server and then onto particular computer systems. I choose the local installation to install it on my computer and click next. In the next window I can choose the options antivirus can perform from the beginning. I choose the intercheck client so it provides security for my computer particularly, I click next. And now at long last the installat ion process starts. It takes quite a while to install it. When it gets to the end another window comes up asking if I want to melt the antivirus now or I just want to finish. The installation is completed.personal effects of the activities These activities are done to maintain the performance and security of computer systems. Antivirus installed on a computer prevents viruses from infecting the computer as well as any other harmful software. That is a key to a fast working computer and secure. Harmful software like viruses can bring a lot of damage to the operating system causing instability and say-so loss of important files. A full system scan is needed after every week of work as many files and webpages were brought on to the system and It needs checking for any harmful units to maintain the security and keep the system fast.Installation of Service Pack 2 patch is needed for new definitions of internet threats as well as performance of the OS. It brings a firewall to the system which protects the computer from harmful software coming in from the internetwork. New performance solutions makes the system faster, more stable and more reliable. Defragmenting hard drives is one of the ways to bring back data integrity lost when doing sure tasks or simply using the system. The files on hard drive get messesd up after time from various causes and need to be put in order to maintain the disk space.
