This is the xfurbish initiative and us the faculty initiative is a servers that supports the integration of technology into education and we do this to a variety of means such you’re currently watching we hope that you’ve had a good time with us even as we explore various topics in technology for education and so today we are covering something a bit new uh we realized that we’ve been covering a lot of online material how to get content for learners and also how as a teacher you can be able to find the resources to improve your skills for online work.
Dissemination of information to students through online means but we also realized that there is something that ties these two quests together and these two quests are tied together by hardware i have oranges all day from mainframe computers which are run by institutions to handhelds such as tablets and mobile phones but today we’ll be looking at something that straddles the middle grounds and so they’ll be looking at personal computers i will be looking at how to select a pc and to do that there are various factors that one needs to consider so that’s what we’ll be looking at today and we hope that by the time we’ll be done in this video you’ll have learned quite a bit and you’ll be encouraged to choose a pc for yourself with ease so what do you look at in the computer first thing to consider is what is it going to be used for someone who just wants to take documents doesn’t need a very powerful machine but if you’re looking to do complex applications.
Data analysis so you may want to edit uh videos and uh and sound we’re going to return that’s a lot more powerful than a computer you for typing documents and sending emails so what you’re going to use for the machine for is a very important factor secondly you need to think about things like portability you may want to use your machine in the office and then again uh use it at home perhaps to watch movies or maybe someone who would want to to access the internet so something that you can be able to at least move around because we have the kind of job that makes you move around a lot so to do that with ease you would want something that’s portable and that’s probably going to be a laptop we will talk about a situation where perhaps you’ve got limited budget to set up a computer lab or buy computers you may want to start with something basic and then over time as far more funds become available you begin to support components to increase the computer’s capacity to do whatever work you have in mind so when you are talking about flexibility to the ability to upgrade the machine with ease that also affects the kind of computer that you buy so you may end up buying a desktop because desktop computers are very easy to upgrade as opposed to laptops where swapping out some components is very difficult for example you can support ram in a laptop as well as in a desktop.
swapping processors optical drives graphic cards can be slightly more challenging when you talk about laptops so as far as flexibility is concerned it may be a good idea to go with the desktop so let’s look at the characteristics of a personal computer that will evaluate when you’re choosing a machine first thing you need to look at is something called the processor so for those who may not be very familiar with what a processor is the processor is the part of the computer that actually does the operations that enable the data to be crunched so to speak processors come from different manufacturers and they come in different models so I’ll briefly go into one of the more popular companies which is intel so intel has different types of processors they’ve got core i3 core i5 and core i7 in increasing complexity, I’m actually the quality processor we run problems with ease you can do you can even type up documents and emails and do some basic work on it but once you start talking about editing videos doing multimedia applications doing statistics and data then if you want a machine that can do that efficiently and with this you’re going to have to look at a processor like a core i5 or a core i7 what these numbers refer to is basically the way the chip is built and the number of processors that are integrated into a chipset it’s actually something that is fairly easy to understand and will attach a guide to this in the description section for this video so apart from that we also have two types of memory to evaluate as well we’ve got a random access memory also known as ram before to use an analogy of the human brain ram is the ability to process information quickly in a sense someone asks you a question or what is five by two you tell them ten even before they’ve been done with the number two ram comes in different sizes these are 4 gb 8gb 16 gb 32gb that’s the range for pcs but once you get to 64 gb or to dgb you’re working into more complex machines you’re going to servers if you have a very fast processor like a core i7 but your ram is limited to something like 4gb your machine’s ability to process information will also be limited so it’s important that um you’re going to have a fast processor just so important that you get enough ram to let you take advantage of the first processing capacity that that chip offers so if you look at the core i3 you can get with 4gb 8gb with ease but you’re going to call i5 core i7 you probably would want to think about starting the minimum 8gb the other type of storage to consider is the hard disk so they had this working by monology where the processor is able to think about very complex issues.
They’re around you think about issues quickly they disk the ability to store large amounts of information and also for a long time it’s long-term storage as well so the different types of hard disks we’ve got such a hard disks and also newer versions called solid state drives ssds so this ssds do not have moving components unlike the sata drives and what happens is that with an ssd you will find that uh accessing information is quick but the flip side to that is that they’re quite expensive and don’t have very large storage so you may want to buy a certain drive especially depending on the kind of project that you want to run if you’re assembling a machine that don’t have very complex dust you don’t need an ssd but you need something that does a lot of work a high-end machine then actually drive is probably something you may want to consider right so that’s about her specifications how the specifications so one of the things one other factor for a personal computer to evaluate is the operating system you have in mind typically speaking most applications that the school would use uh run on the windows operating system are from microsoft and the latest is windows 10 so we may be able to find machines that have the previous version of the os either windows 8 or windows 7 but support for windows 7 has also stopped so it may be a deal to get a machine that has a new operating system something like windows 10 if you perhaps may not have the ability to buy the operating system or you’d want to use uh something different you’ve got linux so linux is what you call open source software is an operating system whose components are available for evaluation and for change by a public whereas software such as windows is actually proprietary which means it won’t be a company and cannot be available to you for you to make changes that you think can be of help to you generally speaking if you are educator you’re going to find machines that have windows or linux because they also have the oldest variety of software written for them finally we also need to think about peripheral devices peripherals you first to input output devices these devices that allow you to input data and also allow you to get output uh whatever has been processed from the from the pc so peripherals should be looking at something like a monitor something like a keyboard also looking at something like optical drives your dvd rom and also your printer if you’re in a place where you need to get information off of dvds or even right uh cds then it may be useful to get so for example a laptop that actually has a dvd rom one other thing to think about when you’re buying your pc is also the issue of cost because it’s an important consideration because you may find that you may not necessarily be able to to get a top-of-the-range machine so this method might influence your choice to either go for a brand new machine or go for a refurb and refurbs are very available in kenya you can actually find them in different shops most of the places you see people talking about xuk these are typically refurbished machines and they may come with a shorter warranty period than the machine that you that that should buy brand new but they’re also Good it can allow you to even buy a machine with aspects for a lower price so it’s a trader if you want to think about and take that into account even as you seek to buy machines for your either for you for yourself or for your facility finally you may want to also find out what kind of after-sales services offered by seller you may want to work ideally with someone who will give you a warranty for the machine and will be able to change path out for you if there’s an issue yeah as opposed to someone who just sell you the machine and tell you’re on your own.
