LAPTOP / DESKTOP COMPUTER has become one of the essential requirement these days.
Computing has reached new heights with super fast development in this area. Every industrial, technical, educational , health or whatever area we think of, these systems have helped human being a lot.
Now, if we think of the use of laptop or desktop computer at home, they are of immense help for us.
Entertainment, work, email, plethora of information on internet, online web series, games and many more tasks can be done on a single device. But many people are much confused when they want to purchase any new laptop.
This article is created to help all the friends who are confused and need help regarding buying a new laptop or desktop computer.
The article discusses the specs, its meaning and other relevant information which will enable you to confidently purchase a new laptop or desktop computer.
A desktop computer is the traditional computer which rests on the desk.
The picture shows a simple traditional desktop computer.
A Laptop is a compact form of desktop computer with a notebook design which gives it a name NOTEBOOK too.
With the advancement of technology, the components were made sleek which enabled them to be put in a compact cabinet measure a few lbs only.
The laptop can be used in a lap, hence the name laptop. It looks like a notebook , which gives it another name NOTEBOOK PC or simply notebook.
The laptop looks like the one shown in the picture.
Go for a LAPTOP if :
We have already discussed the features of a desktop and a laptop computer and their benefits over the other.
We have to make a decision here whether we want to go for a desktop pc or a laptop.
THE MAJOR DIFFERENCE BETWEEN A DESKTOP COMPUTER AND A LAPTOP OR NOTEBOOK COMPUTER IS THE PORTABILITY.
After we have made a choice between a desktop computer and a laptop, it is time to understand the specifications (specs) on the basis of which we are going to make a choice.
The first criteria of choosing a computer is the screen size.
The screen size of the screens are specified in INCHES in diagonal.
The following picture shows the measurement of the screen.
THE DECENT SIZE OF A LAPTOP SCREEN IS 15.6 INCH. LESSER THAN 15.6 INCH STARTS FEELING A BIT SMALLER AND LARGER THAN 15.6 INCH [ THESE DAYS 17 INCH LAPTOPS ARE ALSO IN THE MARKET ] ARE A BIT BIGGER IN SIZE IF WE THINK OF USING A LAPTOP PROPERLY.
The size of the screen should be such that it doesn’t hurt our eyes or stress our eyes.
IF THE SCREEN IS TOO SMALL, WE’D NEED TO KEEP IT VERY CLOSE TO THE EYES AND DUE TO SMALLER LETTERS AND GRAPHICS, IT’LL STRESS OUR EYES.
IF THE SCREEN SIZE IS TOO BIG, IT’LL BE NOT EASY TO SEE THE SCREEN IN A SINGLE FRAME [ THE AREA WHICH IS SEEN BY THE EYES COMFORTABLY ] AND THE BRIGHTNESS WILL CAUSE STRESS TO THE EYES.
THE IDEAL SIZE FOR THE SCREEN OF A DESKTOP OR ALL IN ONE PC IS 19 INCH OR 21 INCH. 17 INCH IS ALSO POPULAR BUT THAT’LL BE A BIT SMALLER. THE GOOD THING ABOUT DESKTOP SCREEN IS THAT WE CAN INCREASE THE DISTANCE BETWEEN THE EYES AND THE SCREEN EASILY WHEREAS WE HAVE KEYBOARD IN OUR HANDS WHICH IS NOT THE CASE WITH THE LAPTOP.
Processor is the heart of cpu. A processor is the device which makes all the processing in the computer right from taking the input upto giving you the output on the screen.
PROCESSOR WITH HIGHER SPEED AND LATEST TECHNOLOGY IS ALWAYS BETTER . BUT AS THE TECHNOLOGY AND STRENGTH GOES HIGHER, SO DOES THE PRICE. CHOOSING THE PROCESSOR IS BASED ON YOUR BUDGET.
TWO MAJOR BRANDS for the reliable processors are INTEL and AMD
FOR INTEL PROCESSOR:
INTEL PROCESSORS are going with generations these days like Tenth generation is the latest.
Generation is further divided in CORE I3, CORE I5 and CORE I7 and sometimes I9 also.
Higher the number , better the speed.
The speed or known as CLOCK SPEED is the measurement for the processors given in Giga Hertz.
More the speed, better the processors.
Now the decision can be done as
10th Gen I7> 10th Gen I5 >10 Gen I3
Same with all the generations.
For the different generations
we can choose like
If we have 9th and 10th generations
we can decide like
10th Gen I5 can be somewhere equal to 9th Gen I7 so we can choose as per the budget.
Similarly older gen I5 can be compared to the new generation I3.
The parameters for the processors are same.
It has Ryzen series and Athlon series. The same parameters can be checked for AMD also.
RANDOM ACCESS MEMORY OR SIMPLY MEMORY IS ANOTHER CORE SPEC WHICH NEEDS TO BE LOOKED AT BEFORE WE BUY A NEW DESKTOP OR LAPTOP.
RAM SHOULD BE AS HIGH AS POSSIBLE ACCORDING TO THE BUDGET.
RAM OR MEMORY HELPS THE COMPUTER STORE TEMPORARY DATA AND ACCESS IT AS PER REQUIREMENT.
When a computer is working, a lot of storage is needed for opening the programs, using them, browsing the internet and so on, this temporary memory is stored in RAM.
HIGHER RAM WILL ENABLE US TO OPEN MANY PROGRAMS AT THE SAME TIME AND AVOID HANGING OF THE COMPUTER. LESSER RAM WILL MAKE THE COMPUTER HANG , IF WE TRY TO OPEN A FEW PROGRAMS AT THE SAME TIME.
Greater than 4 GB of RAM is recommended.
STORAGE is the part of the computer which stores the data permanently.
The storages these days comes GBs. Higher the storage, more space you have to store your data i.e. files, music, videos, programs etc.
Two types of Storage are available these days.
Traditional HDD [ Hard disc drive] and SSD [ Solid State Drive ].
SSD is expensive in comparison with HDD.
SSD HAS HIGHER SPEEDS OF DATA TRANSFER IN COMPARISON WITH HDD. SSD DOESN’T HAVE ANY ROTATING PARTS. SSD IS MORE EXPENSIVE THAN HDD. IT IS SOLELY THE CHOICE OF THE USER TO CHOOSE FROM BOTH ON THE BASIS OF BUDGET.
BENEFITS OF SSD OVER HDD ARE:
BENEFITS OF HDD OVER SSD:
BUY A COMPUTER WITH DEDICATED GRAPHICS CARD ONLY IF YOU HAVE THE REQUIREMENT OF GAMING OR PROGRAMS WHICH NEEDS SPECIAL GRAPHICS CAPABILITY SUCH AS 3D DESIGNING ETC. IF YOU HAVE NO SUCH REQUIREMENT THERE IS NO NEED FOR DEDICATED GRAPHICS CARD.
CD OR DVD DRIVES are known as optical drives.
These drives are almost obsolete and maximum laptop or computer models are skipping them as better storage devices are in market such as usb drives and portable hard disks etc.
Even then if there is any specific need, only then they should be opted otherwise no specific need is there.
Now, when almost all the hardware specs we have discussed, it is time now to know a bit about the OPERATING SYSTEM.
The operating system is the software which is the interface between the hardware and the user.
COMPUTER OR LAPTOP both comes with a operating system these days.
The OS can be WINDOWS, APPLE MAC OS , LINUX, CHROME, DOS etc.
ALWAYS OPT FOR A USER FRIENDLY OPERATING SYSTEM SUCH AS WINDOWS OR MAC. Other OS are requirement specific although they are trying hard to become user friendly and easy to use but still nowhere close to the standard OPERATING SYSTEMS.
LATEST OPERATING SYSTEM IS ALWAYS PREFERABLE.
ALWAYS TRY TO GET AN OS PREINSTALLED AS IF YOU BUY OPERATING SYSTEM FROM THE OPEN MARKET, IT’LL BE COSTLY AND THE CHANCE OF FAKE OS ARE ALSO HIGH.
Battery is a part of the laptop and not provided in a desktop.
Battery is required for the ability of the laptop to work for a few hours without the power.
The rating of the battery is given as Wh [ Read as Watt Hours ]
HIGHER THE BATTERY CAPACITY , LONGER THE RUNNING TIME OF THE LAPTOP. BUT ON THE SAME TIME, HIGHER THE BATTERY, MORE THE WEIGHT OF THE LAPTOP.
Choose your battery by keeping these points in notice.
These were the different parameters which can be taken care before we decide to buy a laptop or a computer.
Now, there are a few more terms which are used these days a lot. Let us discuss those too.
THE HARDWARE SPECIFICATIONS REMAIN THE SAME FOR LAPTOP OR DESKTOP OR THE OTHER TYPES WHICH ARE ABOUT TO BE DISCUSSED NOW.
ALL IN ONE PC IS A PC WITH CPU AND OTHER PROCESSING PARTS EMBEDDED IN THE SCREEN ITSELF. IT ONLY HAVE A SCREEN CONTAINING THE CPU ALSO, A KEYBOARD AND A MOUSE. CAMERA, MIC ETC. TOO PUT ON THE SAME BODY.
A new option for the LAPTOP USERS have emerged as a 2 IN 1 CONVERTIBLE LAPTOP.
A CONVERTIBLE 2 IN 1 LAPTOP is the one with a TOUCH SCREEN [ The screen of the laptop is touch enabled ] with the feature of rotating the keyboard 360 degrees to make it look and work like a TAB.
