Buying a Laptop

Saturday, September 29th, 2007

Purchasing a laptop computer is not an easy job to do because there are so many important things that should be considered before purchasing. Besides the common things that are shared by desktops such as type of CPU, MHZ of processor, size of RAM, size and type of hard disk, brand and support, there are also things like weight, battery life and connectivity.

You can easily transport your laptop from one location to another because of it’s portability. So make sure that a laptop is suited to your needs, as a desktop computer might be a better option.

Laptop technology is getting more sophisticated every day blurring the line between desktop and laptop in terms of performance. Some high quality laptops have several connectivity options such as wireless network cards (to connect to wireless networks), Centrino technology (internet connectivity almost anywhere) and much more.

Business laptops are generally light and ultra-portable and can be used in daily work, presentations and client liasing. These ultra-portable laptops are both expensive and may not have phenomenal performance but if your needs require maximum portability, this would be the best way to go.

Some laptops offer a storage space of 80 to 100 GIGS hard drives but you can increase the space with an external USB hard drive. Laptops generally need at least 256MB RAM to be able to run certain operating systems. Battery life is an important factor when buying a laptop. The last thing you want is to be in the middle of an important meeting and your laptop dying. The latest models offer 5 or more hours of use depending on what you use it for. Gaming and CPU intensive programs will deplete your battery in a lot less time.

When purchasing a laptop you should always make sure it will fulfill all your needs. If a laptop that fulfills your needs is too expensive then get a desktop. There’s no use buying a laptop that is just going to frustrate you in the end.

Laptop Computers

A laptop is a personal computer which is portable. It may also be known as a notebook. The typical laptop will only weight a few pounds and will generally have an internal battery as well as a power adapter.

A laptop is a personal computer which is portable. It may also be known as a notebook. The typical laptop will range in weight from 1 to 3 kilograms, and will generally have an internal battery as well as a power adapter. While most laptops are portable, few can currently match the power of the most expensive desktops, though this will likely change as technology continues to advance. The word laptop was first introduced in 1983, and was used to refer to the Gavilan SC. Despite the name, most laptops should not be placed in your lap if it is not covered, because they can get hot, and can even burn skin that is held against it for extended periods of time. The typical laptop can be powered by one battery, and the power adapter can power the battery when it is plugged into a wall outlet. A laptop can perform many of the same tasks as a PC, but they tend to be limited. They will have the same internal devices which are seen in desktops, but they will be much smaller in size. Most laptops will have a screen which uses a liquid crystal display. Most manufacturers have designed their laptops to work with a keyboard and mouse, and they will also have a touch pad that can be used to move around the cursor on the screen. Laptops come in three varieties, and these are based on the size. An ultraportable laptop will generally weigh less than 1.7 kilograms, while a thin and light laptop will weigh up to 2.8 kilograms, and a medium sized laptop will weigh up to 3.5 kilograms. The idea for the laptop existed prior to the invention of the personal computer, and was first conceived during the 1970s. The very first laptop was the Osborne 1, and it was released in 1981. While the Osborne 1 was massive in comparison to contemporary laptops, it was revolutionary for its time, because it allowed people to carry their data with them, and the computer didn’t have to be left in a single location. However, the Osborne 1 was so large that it was not possible to run it on a battery. Most laptops today now use lithium ion batteries. While laptops have a few advantages over their desktop counterparts, they have some disadvantages as well. Unlike desktops, they are limited in their ability to be upgraded. As of this writing, their is no form factor for laptops, and the costs and technical issues involved with making them easy to upgrade aren’t feasible. The only parts of most laptops that can easily be upgraded are the hard drive and RAM. In addition to this, laptops are expensive to repair if they are damaged, and they are also easy to steal due to their small size. Stolen laptops are a common cause for identity theft. While the use of the USB port has allowed laptops to be upgraded to some degree, it will typically reduce their portability. Historically, the performance of laptops has always been low when they were compared to desktops in the same price range.

Huge New 250GB Notebook and Encrypted 1TB Drives Coming from Seagate

Wednesday, September 12th, 2007

Storage giant Seagate Technology last week announced two large-capacity additions to its mobile and desktop hard drive product lines: A 250GB notebook drive and an encrypted 1TB desktop model.

Both SATA-based products push the edge of technology available for consumers; the 250GB notebook ranks among the largest soon to be available to consumers, and the 1TB Barracuda FDE (which stands for “Full Disc Encryption”) drive likewise is the largest-capacity 3.5-inch consumer-grade desktop drive supporting drive-level AES encryption.

“Data security has traditionally focused on preventing spoofing, sniffing, eavesdropping, denial-of-service and other threats to data traversing corporate networks and the Internet,” said Tom Major, Seagate vice president of Personal Compute Business. “Now that these networks have been hardened and are much more resistant to attack, computer thugs are increasingly targeting the place where data lives – on the hard drive. Seagate is answering this threat with the strongest security available for desktop PC information.”

The new 7,200-RPM,SATA 3.0Gb/sec.-based Barracuda FDE’s drive-level AES encryption feature, dubbed DriveTrust, is designed to improve security even in the event of a drive being removed from its PC. Native drive-level AES encryption – among the strongest encryption technologies available to consumers — also afford enterprises and end users an easy way to junk or repurpose old systems without the effort required to manually erase and re-zero each drive. Instead, they can simply delete the encryption key for each drive.

As with such devices, the Barracuda FDE requires a pre-boot user password to access, and its authentication system is compatible with technologies like biometrics or smart cards. The technology is based on Seagate’s earlier Momentus 5400 FDE-series hard drives for notebooks. As with the Momentus 5400 FDE drives, SDKs are available for system builders to create their own security applications that support DriveTrust.

On the notebook front, the new 2.5-inch, 5,400-RPM Momentus 5400.4 hard drive supports SATA 3.0Gb/sec. and relies on perpendicular recording technology to boost its capacity to 250GB, using two platters. It also boasts some impressive design improvements, with operating and non-operating shock resistances of 325 Gs and 900 Gs, respectively. The drive also continues the Momentus product line’s use of noise-reducing SoftSonic fluid-dynamic bearing motors and QuietStamp ramp-load technology.

Despite the innovations, the hard drive space remains highly competitive. The new Barracuda FDE won’t ship until next year, while the new Momentus 5400.4 is expected to reach system builders only within fourth quarter. At the same time, rival Toshiba has announced a 320GB notebook drive, and expects its minuscule 1.8-inch 160GB drives to debut in advance of this holiday season; the drives sport an astounding areal density of 228GB per square inch.
