Tips for Choosing Notebook

1. Preliminary

Notebook or commonly called a laptop is not a stranger to us. For certain groups who 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 people buy a notebook without a basic knowledge of the basic components that are in it or are often said to specification (spec). So many people found that buy the notebook with a high spec, well-known brand, and price is so expensive, but in

the end is not in accordance with its use. Or conversely, choosing a cheap price, but ultimately could not meet the requirements wanted. Therefore, before choosing a notebook, then we must pay attention to our needs and budget so we do not have any choice.

3. Basic Theory

Some of the important components in the notebook include:

a. Processor

Central Processing Unit (UPP) (English: CPU, an abbreviation of Central Processing Unit), refers to computer hardware that understand and execute commands and data from the software. Another term, the processor (data processing), often used to refer to the CPU. The microprocessor is the CPU which is produced in integrated circuits, often within a single-package integrated circuit memory.

b. Hard disk

hard disk or hard disk drive or hard drive HDD abbreviated abbreviated HD, is a hardware component that stores data and contain secondary magnetic disk. Hard disc was first invented by IBM engineers, Reynold Johnson in 1956. The first hard disk is composed of 50 disks 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, looking hard at the end of the eye disc bertuas arm attached to the disc that can rotate. The data stored in hard disk will not be lost when not given voltage. In a hard disk, there are usually more than one disc to enlarge the capacity of data that can be accommodated. In its development is now a physical hard disk becomes increasingly thin and small but has a data capacity is very large. Hard disks is now not only be mounted inside the device (internally) but also can be mounted on the outside of the device (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 a fixed time not considering the location of the data in memory. This is in contrast to sequential memory devices, such as magnetic tape, disc and drum, in which the mechanical movement of storage media to force the computer to access 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. It was more common to use magnetic main memory.

Semiconductor companies such as Intel started producing his debut with RAM, more precisely the type of DRAM.

Usually 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 a computer to use and modify the information actively, although some tools use some kind of RAM to provide long-term secondary storage.

But there is also an opinion that the ROM is another type of RAM, because it is really too random access such as SRAM or DRAM. It's just that indeed the process of writing the ROM requires a special process is not as easy and flexible as well as in SRAM or DRAM. In addition, some parts of the address 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 standard VGA is no longer used because it has been replaced by a newer standard, VGA is still implemented on the Pocket PC. VGA is the latest graphics standards followed by the majority of computer graphics card manufacturer. Display Windows until now still use the VGA mode is supported by many manufacturers because your monitor and graphics card.

The term VGA is often used to refer to the resolution of the screen size of 640 × 480, whatever graphics card hardware manufacturer. VGA card is useful to translate 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 include ATI and nVidia.

In addition, the VGA can also refer to 15-pin VGA connector is still widely used to deliver analog video signals to the monitor. Standard VGA was officially superseded by IBM's XGA standard, but in fact it was replaced by 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 primary needs that he wants. Utam requirement is meant here is whether the later will be used to design, gaming, system development, or just for mobile. If the laptop is used for the purpose of design and gaming, should we choose the specification of a laptop 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, certainly adjust well with the existing budget funds. For the use of graphic design or gaming, we suggest you choose a laptop with a VGA high power and large memory for design and game play feels more 'light'.

For developing, usually develop the necessary software that requires high resource. We can choose to consider a laptop with a processor and memory with a 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, laptop weight, screen size, as well as some internal features such as wifi, bluetooth, IrDA, NetworkCard, Modem.

Processor is important, therefore we also have to adjust to the needs of our jelly. The selection processor also return to the main needs we had and also adjust our budget. That people often mistakenly is oaring tend to choose processors with high clock frequency even though 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. Notebooks with processors with higher clock frequency is not necessarily convenient to use for 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 the notebook we are comfortable to wear.

b. The size of the notebook.

Apart from the use of selection, some of which must be considered in choosing a laptop is about a big screen, laptop weight and battery life. If we will often use a laptop on the go, you should select a lightweight laptop, with screen sizes that are not too large so as not to trouble him.

Battery life is also worth considering. Generally, laptop batteries can last at least 2 to 3 hours without connecting to the adapter. If you want to save battery usage, turn off functions such as WiFi or Bluetooth connectivity because these functions will increase battery consumption.

c. Sales service.

When about to buy a laptop, do not forget to consider the after sales service ranging from service outlets (many or not easily accessible or not), availability of spare parts and resale price. Do not choose a laptop spare parts it is difficult to find. It is suggested, do not buy a laptop that spare parts it is difficult to find.

This will usually be associated with the brand notebooks. Some brands such as Apple, Fujitsu, Toshiba, Hewlett-Packard, IBM, Dell, Acer is going to have a more expensive price, but in accordance with service and warranty was given. But now there are many local brands that come to compete, such 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 is the notebook usually packaged with the operating system (Microsoft Windows or MAC OS) is already installed on your hard disk with the different versions. In choosing our notebook back on our budget. Because we are guaranteed to use the OS that are legal, but usually Harganyapun will go up, because we actually buy the OS (for Widows usually vary around 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 Linux with a variety of distributions that are available, and open source so no need to buy.
