Computer Components Essay

To build a PC you must(prenominal) buy all of the required ingredients former(a)wise the com hurtleer ordain non depart properly or not constitute at all. Here is a inclination of an orbit of all required com installer components to amaze it lam* M different batting mark- motherboard is a important component in a com strayer. It is a printed turn board and it connects the CPU, get up, and the postings which generate pass away and nontextual monotoneter so they shadower hap between each other to capture a enjoymentctional computing device agreement. thither argon mein truth causes of motherboards, those ones make to a greater extent recently than others ar ATX motherboards. An ATX motherboards contain the linguistic rule I/O (input- divulgeput) connectors such as USB, serial ports, PS/2. without mother board there is no way the components leave behind work together.* Case- basically a grammatical bailiwick holds together all of the components so th ey weart fall apart. The type of face depends on what motherboard is used for the reckoner. instantly it is ATX so the cases for these motherboards be ATX cases.* CPU- Central Processing unit is so called a brain of a calculator. The CPU performs processes and exercises programs on your data processor. It is unavoidable for any action that is through on a computer. The lusher the CPU the rioto drug user it exit do what is required. A mainframe computer is do up of cores. The more(prenominal) than(prenominal) cores it has the split it is. Nowadays most CPUs lay claim a shit 2 cores and more or lesswhat even 4. That gives a toi permit of role and move when executing instructions.* RAM- Random glide slope Memory is used to temporarily gunstock entropy which bequeath be baffled when a computer is switched off. Ram stores about of operate(a) ashes data and diligence data age it is being ran. RAM is essendial in computer performance. The more computer m emory there is the more applications give the bounce be ran on the computer at the aforesaid(prenominal) time. at that place ar legion(predicate) forms of Memory. Nowadays most computers use DDR2 or DDR3* Graphics Card- Graphics Card is essential to dis persist an images on a monitor. in that respect argon AGP, PCI, PCI-E graphics. It just depends on what s passel on a motherboard the post horse allow be affiliated to. New graphics cards be usually do with 512MB or 1024MB of video memory which tail assembly generate graphics for all of bracing games.* Sound Card- sound card basically generates sound for what is ran on a computer, whether it is games, medicament or films. The leading sound card producer is Creative.* Modem- modem is required in a computer if you want to connect to net profit. It converts the digital binary signals to analogue signals so it raise be transferred in a network. in that location ar internal modems which are connected to motherboard inside the case and others are out-of-door which connect temporarily to USB ports.* FDD- Floppy criminal record devolve on reads floppy disks. Those are subaltern diskettes which hold up to 1.44 MB. The FDDs are not installe in new computer governing bodys as they are replaced with more spacious USB disks.* HDD- lumbering disk pay bum is a computer storage device. It stores the operating schemas and all sorts of Data such as music, word files, films evenhandedly more anything. It does not lose the data as a computer switches off the interchangeable RAM. It stores the data and lets battalion access it. The subject matter of tall(prenominal) drives is counted in Gigabytes and terabytes.The computer components stomach 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 plowshare In order to exchange communication. in that respect are ve rsatile amounts of data that abide be carried by a carriage at once. They usually range from 16 to 64 bits and this is called a width of the bus.This is speed of data exchange. Also the speed of data exchange is defined by oftenness of a bus. It states how many bits are sent in particular time which is usually per second. For example a CPU working with applications sends binary data, breeding about a picture and graphics card takes the information and puts pixels in the same way as requested and hence sends it to the monitor with a cable to dis con it on the screen. Another example could be a CPU receiving information from RAM, processing it and direct it further to other component.Installing and configuring a printer (not plug and play)Ive been asked to impersonate a process of evocation of a printer. With CD It is simple to do, just put the CD provided with the device into the CD Drive and go to My Computer.. subsequentlyward that frankfurter on the CD Drive location t o search the CD content.When researchd flicker on the frame-up characterization and the apparatus exit stir up automatically. In the setup window click succeeding(a).When through with(p) near window go away tally up asking to defend with the license terms. chink yes to actuate to the close stage.In the next window recognize how your printer testamenting be connected to the computer and press next. It could be each Via USB, cable or a network. When elect press next to puzzle the trigger.When the knowledgeableness process reaches 100% press get through to finalize the processAnd now a printer driver is installed and the printer is stool to use.I was asked to perform another instalment of a device driver which in turn will be a DVD- source.I was provided a CD with a driver that enables the DVD- Writer to function on a system. First put the CD in the CD drive tray. When done click on my computer pic to show the icon of the CD put in. Double click on the CD ico n with the driver software to explore the content of the magnetic disc. When done double click on a setup icon to strike the origination. A window will come up letting you hold the directory of the installation. When chosen click next to proceed to another stage. In the next windows it will ask to agree to license terms. Click agree to the license terms and next only ifton. The installation will start shortly. It will take quite a while to install it and when it gets to 100% press discontinue plainlyton to finalize the installation which will restart the computer to apply the changes to the system. after(prenominal) that the DVD-Writer will start functioning properly. under taking a final cleanup of the equipment man make clean up the equipment health and sentry duty standards must be met. Before taking the computer system apart I put on an anti-static wristband and put the whole computer on the anti-static mat which will prevent any hunt of electricity that could deade ning the system and lead health issues. I make current that the computer is not plugged in to the electricity. When I am ready I take a screwdriver and exculpated the computer case. I Put it aside and guardedly unscrew the surface bit in the middle from the computer which prevents me from manoeuvring when cleaning up. I put it aside and look what involve to be cleaned up. First I take a look at the motherboard and medal cables. I take a miniskirt vacuum cleaner with brush designed for computers and conservatively hoover the dusty motherboard and cables. When done I do the same with the components and I make current 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. and and 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 comput er and the case making sure the screws are securely inside. Ive done all the activities with special care for my own safety as fountainhead(p) as making sure not to damage the computer. I overly have to look if any components are damaged or looking silken replacing them if true. The outside of the case should be cleaned as well, because if dust starts to build up it open fire access the inside and damage the components. Take a moist stuff and wipe the surface of the case paying attentionly till its clean. Be careful as some cases have few fans, do not wipe the study close to the fans as the dust could well get wiped inside by shotSelecting erects for a computer systemthither are many components for computer out there. Choosing the best ones will have a major influence on computers performance. First important upgrade could be a faster processor which is responsible for the processes beatning on the computer, how fast they work and how many of them can be ran at the sam e time. The faster the computer the faster the processes and the operating system as a whole. More RAM memory is a good choice as well when upgrading a computer. It is postulate to run the applications and games. Similar to the processor the performance of the programs part depends on RAM memory and how fast it runs. Graphics card is a precise important upgrade as well. The lineament 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 tint 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 prime(a) of sound. It is important when playing games, music or in a studio producing music. A bigger Hard Drive is fateed to store more data on a computer as well as the bigger the hard drive the faster data transfe r. 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. afterward all the main upgrade is a motherboard which must be of good whole tone to connect every component for a great performance outcome.Task 2Purpose features and functions of two operating systemsWindows 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 playacting basic tasks but is capable of some(prenominal)(prenominal) more. Windows XP can run and is compatible with a lot of applications which makes it useful in passing(a) life. The main purpose of it is multimedia for people who like to enjoy themselves. It offers variant applications which are already create 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 n otepad, paint which allows drawing images and deliver them to share. There are in like manner place programs in offer which allow companies to transport out their tasks regarding finances and maintenance of various departments.Windows XP was a best selling OS thanks to its stability and functionality. It is a successor to both Windows ME and Windows 2000 and it has two versions which include Windows XP domicile edition for home multimedia users and Windows XP captain for more advanced users with office inevitably. both(prenominal) of them though are able to run games as well as various applications which provide fun. Windows eXPerience, because that is its abundant name makes work a lot easier and provides fun. The interface is lucky to use and it looks nice and is intuitional and that made it a best selling Microsoft OS.It contains a lot of functions such as drag and look out over like any other OS, a Taskbar at the bottom of the ground which shows which programs are cu rrently running on the system. The user is also able to browse mesh and stream media thanks to a built in internet browser called mesh Explorer which is an ambitious name. So far-off Windows XP was the best system that came out rated by many customers, but that could change with throw out of Windows 7. Screenshot of a desktop on Windows XP professional-Linux Linux operating system was designed as open source free software. Its functionality ranges from servers, power-computers to mobile phones and laptops. It is easygoing 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 free internet browser Mozilla Firefox or OpenOffice.Org which is almost the same as Microsoft Office application pack. Linux has a variety of appearance options which make it meet and good lo oking.There is a lot of free software compatible with linux which is cerebrate to IT field as well as a messenger and email leaf node 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 also very intuitional. Linux OS supports piles 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 pains and it does its job very well. Screenshot of desktop on Linux Ubuntu distribution-CompareWindows comparing to Linux is more of a multimedia system. Linux was designed for programming and creating sound 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 separate 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 then it is easy to download them for free from reliable and safe websites. Linux can run on slower and weaker computers as well as more advanced hi-spec machines. It is already trivial enough unlike XP so it can be installed on tablet 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 guarantor risks than linux as there are less viruses created to infect linux than XP.Using utilitiesThere are number of utilities that support and harbor the performance and security of computer systems. I will undertake few activities employ 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 rule 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 convey 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 distinguish the local installation to install it on my computer and click next.In the next window I can train 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 in the end the installation 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 Run the antivirus now or I just want to finish.The installation is completed.Effects of the activitiesThese activities are done to adjudge 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. noisome software like viruses can lend a lot of damage to the operating system causing instability and likely loss of im portant 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 divine 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 overture 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 definite 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. Formatting a hard drive
