Today, all computers have 3 different categories: desktops, laptops (notebooks) and tablets
Many laptops are powerful enough to take over most desktop computing tasks, if not replace your desktop altogether.
Whenever choosing that laptop computer is better for you personally, you have to figure out the kind of function you’ll most often make use of your pc to do. If you want to utilize a laptop to check email, browse the Internet or listen to music, you don’t need anything too powerful. However, if you plan to travel with your computer, store many files or documents and access information, you’ll need a device with a long battery life, sufficient hard-disk space, a memory-card reader, as well as Wi-Fi and Bluetooth connections.
Different categories of laptops:
Netbook
Netbook usually has 7- to 12-inch screens, a full keyboard, and single-core low-voltage CPU. Typical Netbook today has a single-core Intel Atom CPU, 1GB of RAM, a 160GB hard drive, and runs either Windows XP or Windows 7.
Cost less than $500
Ultraportable
With an 11-, a 12-, or a 13-inch display and thin design, an ultraportable weighs a very portable 3-to-4 pounds. They typically use low-voltage CPUs to extend battery life.
Price around $600
Midsize
Midsize laptops feature 13-to-15-inch screens and are a great pick for home use and have dual-core CPUs, most commonly from Intel’s Core 2 Duo line and latest Core i3- or i5-based machine, along with between 2GB and 4GB of RAM, 250GB or larger hard drives, and internal DVD-burning optical drives and an HDMI port.
Price from $400
Desktop replacement
A powerful laptop can replace a desktop computer, providing heavy graphics processing, a big display and lots storage. Desktop replacement laptops feature 16-to-18.4-inch display and have an Intel Core 2 Duo CPU, with more-expensive models trading up to a quad-core Core 2 Quad or the new, more powerful Intel Core i7 processor. The majority of desktop replacement laptops have discrete graphics cards, either for help in playing HD video or for running 3D games. With screen sizes nearing those of personal TV monitors, desktop replacement laptops make good entertainment center, putting your computing, video, and music devices in a single box.
Price from $700
Main features to consider before buy laptop:
Processor:
The central processing unit (CPU) does all the calculations for running your laptop. Processor speeds are measured in gigahertz (GHz). Processors with multiple “cores” basically have multiple CPUs on the same chip. Speeds for multi-core processors describe the speed of each individual core.
Intel and AMD- two biggest CPU makers. Today Intel made about 80% of all CPU on the market. In midsize and high-end laptops, you’ll see Intel Core i7, Core i5, and Core i3 processors. These quad- and dual-core chips offer more power than Atom (use in netbooks) . Intel Pentium and Celeron processors we’ve seen in very inexpensive midsize laptops.
Hard drive:
The hard drive stores software programs, music, video and any other files in permanent memory. If you plan on storing lots of movies and music, you’ll want a larger hard drive or an additional external hard drive. Your hard drive rotation speed is also important. A fast-rotating hard drive (say, 7,200 rpm) will improve the overall performance of your laptop. Laptops, has grown steadily in capacity, can be found with drives up to 600GB in size and even more.
System memory:
Random access memory (RAM) is one of the most important components that will impact laptop speed and overall performance. More RAM will allow you to operate several applications without slowing down your computer or to operate memory-intensive programs, like video editing and games. Most of the laptops offer between 2GB and 8GB of RAM memory.
Screen:
Laptop screens use LCD and LED displays. LED backlit displays offer better contrast and color depth, which is perfect for graphic design or entertainment laptops. Laptop screen size is measured diagonally, running anywhere from below 10 inches up to 19 inches.
Battery:
Most laptop batteries on the market are lithium-ion batteries. Battery life depends on the components in your laptop and how many programs you’re running simultaneously.
Optical drive:
Most new laptops come with a DVD+/-RW drive, which reads and writes blank DVDs and CDs in certain formats. These are useful for backing up your files and creating custom music CDs or DVDs of your home movies.
Networking:
A laptop’s network interface controller (NIC) connects to wired and wireless networks. Most laptops have an Ethernet port as well as built-in wireless networking. The latest wireless standards are 802.11g and 802.11n. You can also purchase wireless broadband cards for use with your cell provider’s wireless network.
In Conclusion
When deciding which laptop is right for you, consider your work habits, weight factor and battery life.
