Choosing a Monitor: For office
& middle class family 19 inch LED is good with quality and prize. The prize
range is 6000-6300 BDT. Now, about Brand. DELL/HP(offer
3yr replacement warranty) is very good for their display resolution.
On the other hand, never choose SAMSUNG manufacture in china those monitor is
very bed display resolution, Negative view from Angle is one of the major
problem. Now-a-days, monitor panel problem is a major issue after a few days’
use, there felt sharp line with different color in panel start and after few
months it’s become useless. By considering these issues chinses monitor offer
very low prize but it’s not offer long lasting guarantee. So always try to buy DELL / HP. With my
eight-year Computer Hardware experience I find that, very low amount of
warranty claim from customer for DELL/HP monitor and other hand, very large
amount of warranty claim for SAMSUNG and another brand. So, Last choice is your
hand.
Choosing a Keyboard: Before buy a
keyboard, few things need to consider, First- comfortability, how much you
comfortable for typing with the keyboard that you choose. Second- Language
painted in the keyboard, if you type for English & Bengali then both
language must be painted to your choosing keyboard that will helpful while you
typing if you’re new. Brand over the year A4 tech is the best brand for
keyboard. A4
tech is comfortable to use, serve long time but
the outlook is not awesome but service is good. prize is little high 480-520
BDT.
Choosing a Mouse: If you want
your mouse serve you long time then A4 tech is best choice. It also very
comfortable to use. But outlook is not gorgeous. prize 250-300 BDT.
Choosing a Casing: Make sure you
buy a casing which offer their own 230VA power supply with casing. Weight of a
casing is very important. The more weight confirms its long-time service. power
switch & re-start switch quality is very important. Check switch quality is
good. Front USB port fittings is very important, check USB port has 2.0 &
3.0 support. Rear cooling fan also important. It’s safe your motherboard from
overheating. Lots of brand not offer
rear fan. So check availability of rear fan. Ware between different port is
very important check ware are good quality in the casing. Negative current
protection is also very important, if casing is not protected then you will
fall shock when touching the CPU. Check before buy. Best brand for above
service in a casing is Delux/perfect
/ Corsair I think those are very good. Prize is between 1800 – 2500
BDT.
DVD writer: Now a day’s it’s hard
to find a good quality DVD writer in the market. reading speed of disc is the
main factor about DVD writer. Best
option to buy DVD writer is Transcend
USB 3.0 DVD writer(offer 1 yr warranty). it is portable so you can
use it for multiple devices. it’s quality is very good. Writing speed also
good. it supports 4X-24X write where traditional internal offer 16X-24X. the
less X the more long time you can use your data CD/DVD. Prize- 2200 BDT. other
side – Internal Samsung/asus/light-on prize : 1000 BDT. Choice is yours.
HDD (Hard disk/ Memory) : For
faster computer you need faster HDD. More RPM more speed. check best RPM of the
HDD. Also, mind that large HDD may slow down your computer. so instead internal
large HDD use external USB HDD if you require large space to store your data. My
suggestion 500 GB is good for computer. Another important think, before buy
check how million’s minute the HDD will workable. My suggestion Toshiba/Western
digital (offer 2yr warranty) very good. Check it is un used and original
packet with sticker. After installing check, it is unpartitioned for confirming
it is never used. Prize: 3500-4000 BDT. Always make a cloud drive to store your
important data backup with google/oneDrive/Dropbox. Cause, Any time HDD may
cursed or damaged. & Recovery of data from damaged HDD is high cost &
can’t ensure 100% of recovery. So, care full.
Processor: A lot of processor
available in the market. Quality of a computer depends on processor. The faster
processor computer will more fast. By considering your budget, you can by dual
core/core i3/ core i5/ core i7/ Xneon/ AMD etc. all processor comes from Intel.
Just need to check the generation of the processor. Regular I hear from people
that get confuse for generation of the processor. For check which gen.
processor you buy just check the series of the processor 3000-4000
( 3rd gen) 4100-5000(4th ) 5100-6000(5th )
6100-7000 (6th) 7100-8000(7th Gen) . Another
important factor- Cache memory of a processor, every generation offer it’s
equal MB of cache memory example 6th gen. 6MB before buy check. And
passing data speed, check how much GHz a processor offer it has range 1.6 to
3.9 GHz so don’t only belief in mothering talk i3/i5/i7 but also check its GHZ.
you buy a core i3 1.6 Ghz processor it will not speedy. core i3 3.7 Ghz will
faster. So before buy check these factors.
Motherboard: A common problem
about motherboard, display not coming, power problem etc. its happed if you buy
a motherboard that cannot support the require voltage to your processor. Best
Brand to buy a motherboard is Gigabyte (offer 3yr warranty).
RAM (Random Access memory) : Apacer,
Twinmos, corsair (offer 3yr warranty) are the best brand of RAM. A lot of
myth in the market that the more RAM the more speed but real fact is that you
have to check how much RAM is support your OS and Motherboard. More RAM then
support by OS and Motherboard is useless. usually, win7 32bit support 4GB and
64 bit 8GB and other type may support more. Another thing check the BUS speed
of RAM, that means instruction movement speed between different component of
the computer more BUS speed is better. and people think, more ram is more speed
8GB come’s with 1333 bus and 4GB with 1600
Bus then 4GB is better then 8GB. GB mean’s Gigabyte that offer how much
virtual memory you can use when computing, more simple word it is for how much
programme you can run at a time not speed. BUS represent the speed.
UPS : its very good practice is a
UPS which backup you computer from electric failure. 650VA is good enough for
home user. Prolink/powerpac (offer 1yr warranty) is the best
brand for UPS.
Antivirus : You can choose free
antivirus but I say you are wrong. For hassle free computing you should buy
good antivirus. Before buy you should think few thinks, which type of virus can
be prevented by you antivirus and also security purpose. I think Kaspersky
because its offer recover damage windows file, and also offer update your
computer apps automatically. with it’s safe money ( your financial activity
protection) apps keep you safe from
hacker. secure connection don’t allow you for spamming. That’s not available
with, norton, avira, panda, trendmicro etc antivirus. But prize is almost
similar.
