What Is CPU?

A CPU stands for central processing unit, which acts as the brain of the computer. It is important when you look at computers that you purchase one with a name brand CPU with high speed. When you look at CPU brands, you want one with a well known reputation that has been in the market for quite sometime. As for the speed of the CPU, CPU speed is measured in GHz. The higher the GHz the faster your computer will run.

What Is RAM?

RAM is the acronym for random access memory, which keeps computers running fast. The more RAM you have the faster your computer will run. RAM only works and functions when your computer is on because it stores temporary files and runs your programs, operating system, etc. In other words, RAM is similar to a person’s short term memory because it remembers every task you perform until it is turned off. If RAM did not clear itself when you turned off the computer, it will store so much useless data that it will eventually overload and crash. This is why is it important to shut down your computer occasionally since you will clear the RAM. Thus, your computer will run faster.

What Is Hard Drive?

A Hard Drive stores data, which allows you to access important files. The hard drive is the computer’s long term memory. Unlike the RAM, which stores unimportant temporary files, a hard drive stores files that matter to you. Every time you save a word document, pictures, movies, etc, they are stored on your hard drive. The amount of storage the hard drive has is measured in GB, which means the higher the GBs the more information you can store.

Sony has incorporated several of its latest technologies in creating this notebook PC. The Sony VAIO Z650 is encased in durable carbon fiber to keep it safe. Complementing its durability is the scratch-resistant LCD that protects its screen.

The built-in G-Sensor shock protection technology is another interesting feature in this Sony VAIO Notebook PC. It protects its HDD from damage and loss of data. When the sensor detects any vibrations, the HDD-head locks up to secure its position, which helps protect the disc from scratching.

You can work fast and efficiently as it contains a powerful Intel Core 2 Duo processor. It also features Sony’s new Hybrid Graphic System technology, a graphics chip switch system that lets you choose either an external or internal graphics accelerator. The XBRITE-DuraView LCD technology with LED backlighting ensures fine pictures with vivid colors and uniform brightness.

This notebook has everything you need. You can download a lot of stuff. Its 320 GB HDD helps you to store data endlessly without ever deleting any. And, its 4 GB of memory allows you to run many applications simultaneously. You can even get a customized laptop with increased HDD capacity and with many more software/hardware at Portable One.

Also, you don’t have to buy a separate web cam and connect it because this Sony VAIO notebook PC comes with built-in web cam (and a microphone too.)

Such is the beauty of the Sony VAIO Z650 that anyone who sees it can hardly resist. If you are ready to shell out some money, I would advise you to go for the Z650.

Like other Sony notebooks, the keyboard on the VAIO X is island-style, but at 88 percent of full size, it’s a bit smaller than most netbooks with 10- to 12-inch screens. Measuring 9.5 x 3.5 inches, the keyboard is about half an inch smaller in both directions than the Toshiba mini NB205, even though the VAIO X has a larger keyboard deck. This is because there’s about half an inch of space on either side of the keyboard.

The display itself again split opinion, though. It has a notable red bias, which affects skin tones, and its horizontal and vertical viewing angles are a little limited. You could also argue that its 1,366 x 768 resolution is too high for an 11.1in screen, although if you’re finding it a struggle to read system text you can enlarge it easily via Windows 7. In terms of features, the X-Series includes pretty much everything you could ask for. There’s Bluetooth, 802.11bgn WLAN, an integrated 3G modem that supports up to 7.2Mbits/sec, and a 0.3-megapixel camera.

With a single core Atom processor, the Vaio X Series was never going to be a great performer. Even though the 2GHz Z550 chip supports hyper-threading, this is no substitute for the performance of the dual core processors used in most other laptops, and the Vaio felt a little sluggish at times. Our review unit was rated at just 2.5 under the Windows Experience Index built into Windows, but this score was held back by the low performance of the Intel GMA 500 graphics function in the chipset, while the memory and disk scores were quite respectable. However, like netbooks (which also use Atom processors) the Vaio has ample performance for productivity tasks such as word processing, email and delivering presentations.

Performance was also possibly affected by the presence of various pre-installed applications, such as 60-day trial versions of Norton Online Backup and McAfee Security Center, which run every time the computer starts regardless of whether you accept the 60-day trial conditions or not.

The netbook’s 128GB Samsung SSD booted to Windows 7 Home Premium in 50 seconds (while the average is 55 seconds), and was able to copy a 4.97GB folder of mixed media files at a rate of 27.2 MBps—close to twice the netbook average of 15.2 MBps. When converting a 114MB MPEG-4 to AVI using HandBrake, the VAIO X took 26 minutes and 45 seconds; that’s just under 3 minutes faster than the netbook average, but the average ultraportable laptop takes 14:06. The Acer Aspire Timeline 1810T, for example, took 11:24.

Despite its low weight, the X Series still provides a decent range of connectivity options, consisting of 802.11b/g/Draft n Wi-Fi, Bluetooth and a built-in Everywair HSDPA modem for wireless broadband, enabling buyers to stay connected virtually anywhere. It also has two USB ports, VGA output, Ethernet connector, headphone jack socket and two slots along its front edge for SD Card and Sony’s own Memory Stick Pro Duo Flash storage cards. As a measure of just how thin the Vaio X series is, a hinged cover forms one half of the Ethernet connector, because the laptop’s chassis is too thin to accommodate a standard size Ethernet jack.

The laptop’s 11.1 inch screen and 6.5 hours of battery life is also respectable. Snap on an optional larger battery and your battery life jumps to 14 hours. This is of course also thanks to the Windows 7 OS and solid state hard disk under the hood which is optimized to greatly improve battery life compared to past laptops.

Sony’s Vaio X Series is incredibly thin and light and, with a better battery life than we expected, seems an ideal machine for those who need to carry a laptop around with them. However, this model is pricey even by Sony Vaio standards, and buyers would be advised to treat it with care as we have doubts about the system’s robustness.

The Sony VAIO Z590UBB Notebook also comes in with a NVIDIA GeForce 9300M GS graphics processing unit that provides powerful visual computing features. It is perfect for your daily computing needs.

I’ve already mentioned about the XBRITE-DuraView LCD technology and how it helps prevent scratches. To add to this, it also delivers a picture quality that is just amazing.

You can secure this Sony VAIO Notebook PC with the inbuilt biometric fingerprint scanner quickly and easily. An integrated Trusted Platform Module (TPM) lets you control access on a specific client/user basis, enhancing the security system further.

As far as network connectivity goes, the Sony VAIO Z590UBB Notebook offers ample options – Gigabit Ethernet, Wi-Fi, and Bluetooth. With a battery that lasts up to 6 hours, the Sony VAIO VGN Z590 Notebook is definitely a smart buy.

The Intel Centrino Core 2 Duo T6570 2.1 GHz processor and the 3 GB RAM (expandable up to 4 GB) will take care of the performance part. The 160 GB Serial ATA hard disk along with DVD-RAM/±R/±RW and memory card reader are the storage devices on this Sony VAIO NS215N Notebook. Its 15.4″ WXGA widescreen display uses XBRITE-ECO technology and GMA 4500MHD graphics card to produce clear and bright images. A battery run time of up to 4 hours will keep you going for hours together.

If you are someone who spends hours on the internet and likes surfing the net on the move, then this Sony VAIO NS Series notebook provides strong connectivity features with Wi-Fi Gigabit Ethernet, built-in modem, and an express card slot. You are just a click away from sharing your photos on the web with an integrated webcam in place. There are four USB ports (two on each side) to connect your external drives and devices. Windows Vista Business comes pre-installed in this Sony VAIO NS Series notebook.

The Sony VAIO NS215N Notebook can be customized and certain components upgraded at Portable One Inc, I upgraded the processer and RAM recently, I found it make a huge difference on the performance.

I have used this Sony VAIO NS Series notebook extensively since the time I bought it and it has responded very well. If you want a laptop for the long run, do not have second thoughts about buying the Sony VAIO NS215N Notebook.
