Notebook or laptop is not a so-called foreign to us. For certain groups that have high mobility, for example mahsiswa, notebook instead is something that becomes a need to support their work. The development of the notebook was already growing rapidly and the price is also more accessible.
2. Background
Often times people buy a notebook without a basic knowledge of the basic components in it or are often said to the specifications (spec). Encountered so many people who buy a notebook with a high spec, well-known brand, and the price is so expensive, but in the end is not in accordance with its use. Or alternatively, choose a low price, but ultimately do not meet their wants. Therefore, before choosing a notebook, then we must pay attention to our needs and budget so that we do not have the wrong choice.
3. Basic Theory
Some of the important components in the notebook include:
a. Processor
Central Processing Unit (UPP) (English: CPU stands for Central Processing Unit), refers to computer hardware to understand and execute commands from the software and data. Other terms, the processor (data processing), often used to refer to the CPU. The microprocessor is a CPU that is produced in integrated circuits, often within a single integrated circuit package memory.
b. Hard disk
hard drive or hard disk drive or hard drive HDD abbreviated abbreviated HD, is a hardware component that stores data and contains the secondary magnetic disk. Hard disk was first invented by IBM engineers, Reynold Johnson in 1956. The first hard disk is composed of 50 discs measuring 2 feet (0.6 meters) with the rotational speed reaches 1200 rpm (rotation per minute) with a storage capacity of 4.4 MB. Hard disks today there are only 0.6 cm wide with a capacity of 750 GB.
If opened, the eyes look hard discs on bertuas cuffs attached to the disc that can rotate. The data stored in hard discs will not disappear when not given voltage. In a hard disk, there is usually more than one dish to increase the capacity of data that can be accommodated. In development now are physically hard discs become thinner and thinner and smaller but has a capacity of very large data. Hard disk is now not only be installed on the device (internal) but can also be mounted outside the (external) using a USB or FireWire cable.
c. Memory (RAM)
Random access memory, RAM, is a type of computer storage whose contents can be accessed in any order that the data is in memory. This is in contrast to sequential memory devices such as magnetic tape, disk and drum, in which the mechanical movement of the storage medium forces the computer to access the data sequentially.
First recognized in 60'an. It's just that time of semiconductor memory has not been popular because the price is very expensive. When it is more common to use a magnetic main memory.
Semiconductor companies like Intel debuted with the manufacture of RAM, more precisely the type of DRAM.
Usually the RAM can be written and read, as opposed to-read-only memory (read-only-memory, ROM), RAM is usually used for primary storage (main memory) in computers to use and modify information actively, although some tools use some type of RAM to provide long-term secondary storage.
But there is also the opinion that the ROM is another type of RAM, because it is also true random access as well as SRAM or DRAM. It's just really the process of writing the ROM requires a special process is not as easy and flexible as well as the SRAM or DRAM. In addition, some parts of addres space of RAM (main memory) of a system that is mapped into one or two-chip ROM.
d. VGA
VGA stands for Video Graphics Adapter, is an analog computer display standard first marketed by IBM in 1987. Although the VGA standard is no longer used because it has been replaced by a newer standard, VGA is implemented on the Pocket PC. Is the last VGA graphics standard that is followed by the majority of computer graphics card manufacturer. Display Windows still use VGA mode is supported by many manufacturers because of the monitor and graphics card.
The term VGA is often used to refer to a resolution of 640 × 480 screen size, no matter what graphics card hardware manufacturer. VGA card is useful to interpret the computer output to the monitor. For the graphic design process, or play
video games, needed a high-powered graphics card. Well-known manufacturer of graphics cards such as ATI and nVidia.
In addition, the VGA can also refer to the 15-pin VGA connector is still used widely to deliver the analog video signal to the monitor. Standard VGA was officially superseded by IBM's XGA standard, but in fact it was replaced by a Super VGA VGA.
4. Discussion
The discussion this time will be reviewing how to choose a notebook to fit the needs that we want. Several considerations should we think about is:
a. Our main requirement.
Often people buy a notebook without considering the main requirement that he wants. Utam requirement in question here is whether the latter are used for the design, gaming, system development, or just for mobile. If the laptop is used for design purposes and gaming, we should choose a laptop specifications with emphasis on the VGA card (Video Graphics Array) and a reliable memory. If we want a laptop with a higher capacity, choose a multi-core technology and 64-bit architecture is highly recommended, of course, also fit with the existing budget funds. For the use of graphic design or gaming, you should choose a laptop with a VGA high power and large memory in order to design and game play feels more 'light'.
For developing, usually develop needed software that requires high resource. We can choose a laptop with a processor and memory considering the high specification in order to balance the development of software and developing tools that were increasingly 'greedy' memory. Multi-core technology and 64-bit architecture is also recommended.
For mobile, you can emphasize the choice of battery life, weight of the laptop, screen size, as well as some internal connectivity features such as wifi, bluetooth, IrDA, NetworkCard, Modem.
Processor is important, therefore, we must also adapt to the needs of our jelly. The processor's election back to our main needs and also fit our budget. That people often mistakenly is oaring likely to choose a processor with high clock frequency when the price will be more expensive, so the expense of memory and VGA card. Though the performance of the notebook tersebu not solely be seen from the processor. Notebook with a processor with high clock frequency is not necessarily convenient to use for the design and gaming or developing. So in the end we must be very clever to integrate processor, memory, hard disk, and VGA cards so that our notebook comfortable to wear.
b. The size of the notebook.
Apart from the use of selection, some of which should be considered in choosing a laptop is about a big screen, laptop weight and battery life. If we will often use a laptop on a trip, you should choose a lightweight laptop, the screen size is not too large so as not to trouble him.
Battery life is also worthy of consideration. Generally the laptop battery can last at least 2 to 3 hours without being connected to the adapter. If you want to conserve battery life, turn off functions such as WiFi or Bluetooth for these functions will increase battery consumption.
c. After-sales service.
When about to buy a laptop, do not forget to consider the after sales service from service outlets (many or not easily accessible or not), availability of spare parts and resale price. Do not choose a laptop that spare parts are hard to find. It is recommended, do not buy a laptop that spare parts are hard to find.
This will usually be associated with brands of notebooks. Some brands such as Apple, Fujitsu, Toshiba, Hewlett-Packard, IBM, Dell, Acer is going to have higher prices, but in accordance with the service and warranty that it provides. But now many local brands that compete as Axio, BYON, and others who offer cheaper prices, but it certainly should be smart in the sevice that will be obtained.
Another thing you may need to be considered is the existing operating system. Now this notebook is usually packaged with the operating system directly (Microsoft Windows or MAC OS) is already installed on your hard disk with different versions. In choosing a notebook it's back on our budget. Because we are guaranteed to use the OS that are legal, but usually the price for Samsung will come up, because we actually buy the OS (for Widows will usually differ about 100 U.S. $). Because it is advisable to buy a notebook that tdak bundled with the OS, so that we can use the remaining funds available for memory or VGA. For the OS, if we want to remain legal, we can use with various distributions of Linux available, and open source so it does not need to buy.
