Before  buying a computer, call it a laptop or desktop, there are some things you are going to look at first.

Some of us, when we want to buy a computer, we do always look at the price of the computer first without even checking whether the computer we are buying at that price is going to serve our needs. Some will say, "I want a computer or a laptop of #20000, 25000;" some will even say "I want a laptop that will  not be more than #15000." Just imagine, a person looking for a laptop at #15000. Do you think that person truly need a laptop or that the person just want to answer a laptop owner. What service do you think a laptop at #15000 will render - except if the person want to be using it to play musics and to watch videos or to do less typing using either Microsoft word or other Microsoft packages. I doubt if such a Laptop will be used to run soft 3D applications - I mean soft ones,  like Auto-cards, etc.

So, before looking for a laptop, you will first of all know the reason why you need that laptop or what you want to use the laptop to do first before looking at the price, that will help you to get the suitable one.


  • How strong is the laptop i.e. the company that produces the laptop: Most of us do make mistakes here. Most of us do think that HP or COMPAQ is the strongest laptop we have, but it is not the strongest, rather it is one of the strongest. Most of us don't know about TOSHIBA laptop and how strong it is. If I may be asked, I will say that TOSHIBA laptop is the strongest laptop because the battery can last, it is always difficult for it to have board problem, etc. But most people are already used to HP or COMPAQ laptops, well, it is not bad because HP or COMPAQ laptops are also a good and strong laptop.
  • Processor type/speed: This is the one of the important things you have to look at before buying any laptop. We have two company's that manufactures processor, they are: INTEL and AMD. It is somehow difficult to say which one among the two companies produces the strongest processors. But there is always one difference between them. AMD produces processors with good graphics, while INTEL produces more stronger processors. 
Some processors produced by AMD are: Vision, Athlon, Sempron, Turion, Opteron, etc. While those produced by INTEL are: Pentium (2, 3, 4, M, D), Celeron, Duo Core, Core 2 Duo, Core ix (i3, i5, i7), etc.
AMD also has Duo Core.

All these are the types of processors we have. So when buying a laptop, check the type that will be ok for you. If you want to use the laptop to run 3D  application or to run higher packages, such as, Auto-Cad, Programming packages, Web design, etc., I advised you should go for Duo Core or at least, Celeron. For other types of processors, you can use them to execute other soft programs. But I will advise you not to go from P3 - down because it will slow the operation of the system.

For processor speed, we have, MHz, GHz. E.g: 600MHz, 1.88GHz, 2.20GHz, etc. As it increases, so does the speed of your laptop increase.
  • Size of Hard Disk/Type: I don't need to emphasize much on this one because most people have known it.The Hard disk is a storage device used to store data or information permanently in the computer system, even when the system is OFF, the data will always be there.  Under Hard disk drive, we two types, they are: IDE and SATA hard disk drive. Two of them are the same only that the IDE has pin at the head while SATA has no pin. IDE is the old head while SATA is the newly introduced HDD. Based on size, we have; KB, MB, GB, TB which increases respectively. TB means TERABYTE.
  • Size of RAM: RAM which means Random Access Memory is used to store data temporally in the computer system while the computer is still ON but data disappears immediately the computer is turned OFF, unlike the hard disk. RAM also determines how many works that can be performed on a computer at a particular time. It also helps to increase the speed of your computer. Like HDD, RAM can also be measured in KB, MB, GB, etc. which also increases respectively.
  • Finally, The CD/DVD Rom Drive: They are generally called OPTICAL DRIVE. They are of two types; CD and DVD Drive. CD plate can play in both CD and DVD Drive but DVD plate can only play in DVD Drive only. 
This OPTICAL Drive is classified into three, they are: Non Writable, Writable, and Rewritable Drive. Non Writable cannot write any plate. Writable can write a plate but cannot rewrite. While Rewritable can write and rewrite a plate. This is the only difference between them. 

This things stated above are the major things to consider before or when purchasing a laptop. So therefore, these are going to determine THE PRICE OF THE COMPUTER OR LAPTOP YOU WANT TO BUY. The Higher The Configuration, The Higher The Price.

When buying any computer or laptop, first know the reason why you want to buy the computer or what you want to use it for, then you determine the configuration that will suit it. After that, you can now begin to look at the price of the laptop or computer.

    liquid. If a hand blender is employed, then this
    soup is just not required to become transferred as well as the pureeing of the soups or sauces
    can be done in the kitchen utensil itself. ©eing peas, carrots and beats in to a vegetable
    medley of soft baby foods.
