Introduction
In this assignment i will explain and present the facts and figures on the knowledge i have gathered from the cisco curriculum at http://www.cisco.com/web/learning/netacad/index.html and http://vendorlib/curr/ITE/start.html. this post will talk all about chapter 6 in curriculum which covers laptops and portable devices along with their components, the standards of phones and the configuration of a laptop. lastly it will talk about how to trouble shoot laptops, portable devices and how to identify maintenance techniques for them as well.
laptops and portable devices
the very first laptops were very expensive for people to buy and were also very heavy. Over the years now laptops have dropped in price dramatically to what they were when they first came out. Not only has the price dropped but the weight has decreased so they are easier to carry round. laptops can now have certain things added to them such as fire walls, cameras and video ports etc. Other portable devices other than laptops are things like smart phones and PDAs. PDAs are used to organise and help arrange things, they also benefit in apps such as a calender, contacts book, calculator and many more. smart phones can do all that a PDA can, maybe slightly less apps, but they can also phone and message people. As you can tell PDAs have gone out of fashion quite a bit now as smart phones have taken over being capable of fulfilling more things than the common PDA.
laptop components
components of a laptop are quite different compared to desktop components as they are put into a completely different casing and wouldn’t fit in a desktop case. laptops have been able to get better and smaller as the components within the case of the laptop are shaped to fit in sync with all the other components making it more compact. as well as internal components there is also external components that benefit in many ways. some of these are the key board, the touch pad, the monitor even the battery and in older models the nipple also like the touch pad, you use it to navigate the mouse across the screen, but it is allot harder to use.
ports and sides of a laptop
usually the base of the laptop holds the access to the battery, the memory and sometimes the hard rive. Also in some older models the base of the laptop can have a docking bay port used to connect the docking station. on the back of the laptop there is an AC power port and a parallel connector port. on the side of a laptop there is many, many various ports to help enable many things. There are USB ports, Ethernet ports, s-video ports, head phone and micro phone jacks, expansion slots and ventilation grills, VGA ports and disk drives. lastly the front of the laptop would usually have the least amount of things. It consists of things like speakers, blue tooth or in fared ports and the switch or latch used to open the laptop lid. All these these things help to create the basic out line and casing for the laptop.
keyboards and features
when the laptop lid is opened it allows many more keys and features to be accessed. now in the 21 st century pretty much all laptops have a touch pad built into them along with a keyboard. there is also the standard power button and on some older models there are some volume keys built in. on some ADVENT models are symbols that can be viewed at the front. Each symbol represents something different. there are battery symbols, wireless symbols, blue tooth/ infra-red symbols, whether a num or caps lock is enabled or disabled and last but not least the stand-by symbol.
laptop and desktop component caparisons
desktops and laptops contain many various components which fore fill many actions to benefit your needs that you wish to complete on the computer no matter what it is, all the components do something or there would be no point in putting them in the laptop/desktop. most of the things a desktop can do, so can a laptop the only main difference is the fact that the laptop is portable. although both these have more or less the same components they are both arranged and placed differently in the case, and there parts cannot be swapped with each other as they are made and formatted differently. in some cases desktop components as the are standardized, where as if a laptop tries to share the same part it is unlikely they could as it they are made specifically to be compact and manufactured so they fit in the case as that brand have designed it.
maintenance
if you know how to do it maintaining your laptop can become simple. first thing to know is how to keep your laptop clean and in a good condition. before you use any cleaning devices like compressed air you need to make sure every thing is turned off and no devices are connected to the laptop, also make sure that the components can be cleaned with what ever you are going to use to clean them or they may not work again. vents and fans should use compressed air, LCD screens should be wiped over with a soft piece of cloth. drives can be cleaned with cleaning disks. lastly disks can be cleaned with lint free cloth. by Luke Nutter
