Mac Book

noreply@blogger.com (Vash) — Thu, 22 Oct 2009 22:33:00 +0000

From the durable unibody enclosure to the radiant LED-backlit display, the new MacBook is the must-see notebook of the season.

Durable unibody enclosure.

A mere 1.08 inches thin and even lighter at 4.7 pounds,¹ the sleek new MacBook cuts a slim profile on any desk (or in any backpack or briefcase). It features a new seamless, more durable unibody enclosure with rounded contours that make it easy to pick up and slide into and out of your bag. And it’s made of rugged polycarbonate that withstands the rough and tumble of everyday life — at school, at work, or while traveling. Even the bottom of the new MacBook feels different. Covering its entire surface is a nonslip material that keeps your MacBook right where you put it, whether on a desk, table, or airplane tray.

Unibody design

The breakthrough unibody design of the MacBook Pro comes to MacBook.

Quality screen time.

MacBook now features an LED-backlit 13.3-inch glossy widescreen display for an even more spectacular viewing experience. Documents, videos, photos, and games look incredibly sharp and detailed. The LED backlighting delivers stunning colors and instant full-screen brightness the moment you open the lid. And its 1280-by-800 pixel resolution offers an outstanding balance of luminous color and easy readability in a perfectly portable size.

Spacious glass Multi-Touch trackpad.

The new MacBook Multi-Touch trackpad has no button because it is the button. That means there’s plenty of room to move your fingers around, and you can click anywhere — left, right, center, and everywhere in between. The trackpad features a silky smooth glass surface that feels great to the fingertips. Use it to perform familiar functions such as right-click or two-finger scroll as well as Multi-Touch gestures: pinch to increase font size in a document, rotate your fingers to reorient photos, swipe to navigate through web pages, and more.

A comfortable keyboard your fingers will love.

MacBook portability doesn’t happen at the expense of key features. The keyboard is full size, with keys that are curved to contain your fingers and highly responsive to your touch. Its low-profile design integrates perfectly into the unibody enclosure, so you’ll get a comfortable experience whether you’re typing a quick email or writing a lengthy research report. The keyboard also gives you one-touch access to music and video controls and Mac OS X features such as Dashboard and Exposé.

Magnetic latch

Because the latch has no moving parts to snag, jam, or break, even opening and closing your MacBook is a pleasure.

Easy access to connections and ports.

The connections and ports on MacBook — MagSafe power, Gigabit Ethernet, Mini DisplayPort, USB, and audio in/out — are all smartly integrated on the same side of the notebook. So your cables stay neatly organized, and connecting and disconnecting your devices is easy and convenient.

MagSafe Power Adapter

The power cord is held in place magnetically, so if someone should trip over it, the cable disconnects harmlessly and your MacBook safely stays put.

Clean, simple interior design.

MacBook is as well designed on the inside as on the outside. Turn it over and you’ll notice a seamless, sturdy, single-piece bottom case with no battery compartment. That’s because the lithium-polymer battery in the new MacBook is strategically built right into the enclosure. In addition to providing extra overall durability, this integrated design eliminates the space-consuming parts required by a removable battery. This allows more room for a larger-capacity battery that can run up to 7 hours on a single charge² — all in an enclosure that is just as thin and even lighter. When you remove the bottom case, you’ll discover a clean, simple interior layout that makes it easy to add more memory or a larger hard drive.

Mac Mini features

noreply@blogger.com (Vash) — Thu, 22 Oct 2009 22:28:00 +0000

Full - Size features.
A faster processor, more memory, more hard drive space, and more power fit inside one small square. And Mac mini makes room for even more.

Memory and processors.

Mac mini is anything but mini under its hood. With either 2GB or 4GB of memory, Mac mini gives you twice as much memory as the previous generation. So now you can run more applications at the same time. You also get a 2.26GHz or a 2.53GHz Intel Core 2 Duo processor, a blazing-fast 1066MHz frontside bus, and 3MB of L2 cache.

Mac Mini

noreply@blogger.com (Vash) — Thu, 22 Oct 2009 22:09:00 +0000

Brilliance Squared

There’s nothing like Mac mini. At just 6.5 inches square and 2 inches tall, it’s designed to take up far less room — and use far less energy — than any other desktop computer.

Small. Simple. Beautiful.

Mac mini has a sleek, anodized aluminum case and clean, white surface. It’s small, elegant, and unassuming. In fact, it looks so simple it's hard to believe it’s a computer at all.

Packed with power.

Mac mini was engineered to fit a lot of computer into a little space. It’s powered by an Intel Core 2 Duo processor, with advanced NVIDIA graphics and fast DDR3 memory. There’s plenty of storage space — up to 500GB¹ — for just about anything. And it comes with Mac OS X Snow Leopard, the world’s most advanced operating system. Who knew something so small could be so huge?

Plug. And play.

Mac mini includes five USB 2.0 ports and one FireWire 800 port, so you can connect your keyboard, mouse, iPod, iPhone, digital camera, DV

camcorder, external hard drive, printer, and any other peripherals you use. Mac mini even lets you connect up to two displays, including your TV, with the mini-DVI port and Mini DisplayPort. On the front of Mac mini is the ultrafast, slot-loading SuperDrive for playing DVDs and CDs — or burning your own.

The many uses of Mac mini.

Because Mac mini is so small, it can be just about anything you want it to be. And be amazing at it, too. Officially, Mac mini is a desktop computer. But because it can go places no other desktop can go, it’s been used everywhere from boats to server rooms, as the heart of an entertainment center — and even to power robots.

Magic Mouse

noreply@blogger.com (Vash) — Wed, 21 Oct 2009 17:00:00 +0000

It began with iPhone. Then came iPod touch. Then MacBook Pro. Intuitive, smart, dynamic. Multi-Touch technology introduced a remarkably better way to interact with your portable devices — all using gestures. Now we’ve reached another milestone by bringing gestures to the desktop with a mouse that’s unlike anything ever before. It's called Magic Mouse. It's the world's first Multi-Touch mouse. And while it comes standard with every new iMac, you can also add it to any Bluetooth-enabled Mac for a Multi-Touch makeover.

Seamless Multi-Touch Surface
Magic Mouse — with its low-profile design and seamless top shell — is so sleek and dramatically different, it brings a whole new feel to the way you get around on your Mac. You can’t help but marvel at its smooth, buttonless appearance. Then you touch it and instantly appreciate how good it feels in your hand. But it’s when you start using Magic Mouse that everything comes together.

The Multi-Touch area covers the top surface of Magic Mouse, and the mouse itself is the button. Scroll in any direction with one finger, swipe through web pages and photos with two, and click and double-click anywhere. Inside Magic Mouse is a chip that tells it exactly what you want to do. Which means Magic Mouse won’t confuse a scroll with a swipe. It even knows when you’re just resting your hand on it.

Laser-Tracking Engine

Magic Mouse uses powerful laser tracking that’s far more sensitive and responsive on more surfaces than traditional optical tracking. That means it tracks with precision on nearly every surface — whether it’s a table at your favorite cafe or the desk in your home office — without the need for a mousepad.

Wireless

Magic Mouse connects wirelessly to your Mac via Bluetooth, so there’s no wire or separate adapter to worry about. Pair Magic Mouse with your Bluetooth-enabled Mac and enjoy a reliable and secure connection up to 33 feet away. When you combine Magic Mouse with the Apple Wireless Keyboard, you create a workspace free of annoying cables.

And because Magic Mouse is wireless, it can venture beyond the confines of your desk. A quick flick of the on/off switch helps conserve battery power while Magic Mouse is tucked in your bag. Even when it’s on, Magic Mouse manages power efficiently, by detecting periods of inactivity automatically.

Make one great gesture after another.

Multi-Touch technology on the iPhone and iPod touch introduced a breakthrough way to interact with your content. Magic Mouse, with its Multi-Touch surface, does the same thing for your Mac. When you use gestures, it’s as if you’re touching what’s on your screen. For instance, swiping through web pages in Safari gives you the feeling of flicking through pages in a magazine. And scrolling with Magic Mouse isn’t your everyday scrolling. It supports momentum scrolling (similar to iPhone and iPod touch), where the scrolling speed is dictated by how fast or slowly you perform the gesture.

Laptop with flexible Display

noreply@blogger.com (Vash) — Fri, 16 Oct 2009 12:06:00 +0000

Brave German designers are not shy about experimenting with form. Of course, the day when such a concept could be put into practice, will not soon, despite the existing achievements in the field of flexible OLED-screens.

The idea is simple - there is a small tube with a wire, standard connectors and speakers.
At his literally wound rolled in a tube display, which is practically a slight movement of the hand can be easily turned into a laptop screen with a keyboard and large display.

And with great desire in the display still appears and folding legs. We all love these concepts precisely because of what they look spectacular and much promise.

Gmail outage caused by overloaded servers

noreply@blogger.com (Vash) — Thu, 03 Sep 2009 02:42:00 +0000

A worldwide outage of Google's Gmail online e-mail system on Tuesday was caused by a traffic jam on its servers, according to Google's official Gmail blog.

The problem was that some recent changes designed to improve traffic flow on request routers, servers designed to direct Web queries to the appropriate Gmail server, overloaded the system after workers took some Gmail servers offline to perform routine upgrades.

The overload resulted in people around the world being unable to access Gmail for about 100 minutes, Treynor said, though he noted that IMAP/POP access and mail processing continued to work normally.

Windows 7 RTM arrives for Volume License customers

noreply@blogger.com (Vash) — Wed, 02 Sep 2009 14:35:00 +0000

Windows 7 RTM has been made available to Volume License customers. Windows 7 Professional has been marked down 15 percent for the next six months.

Microsoft today made it possible for businesses to order Windows 7 and Windows Server 2008 R2 upgrades from a Microsoft Volume License Reseller. The Volume Licensing (VL) option is for businesses that don't already have Software Assurance and want to upgrade their existing business PCs to Windows 7.

A recent survey found that the majority of businesses were not planning to deploy Windows 7 before the end of 2010, so it's not surprising Microsoft is doing everything in its power to push the new operating system. more

AMD aims to stay in the race with Magny-Cours 12-core CPU

noreply@blogger.com (Vash) — Wed, 02 Sep 2009 14:23:00 +0000

At the recent Hot Chips conference in Palo Alto, AMD outlined its upcoming 12-core server processor, codenamed "Magny-Cours." The new CPU will arrive in 2010, and will fit into the same power envelope as the existing six-core Istanbul processor. But to make that happen, AMD had to make some compromises.

Due in 2010 on AMD's 45nm SOI process, Magny-Cours uses the same basic core microarchitecture as the current Shanghai quad-core server processor, so if there's any improvement in per-thread performance it will have to come from better system design.

The basic idea behind Magny-Cours is simple: take two six-core Istanbul processors, downclock them a bit to reduce power, and squeeze them into a multichip module (MCM) so that they can fit into a single socket. By using an MCM, AMD will be able to fit 12 cores into the same thermal and power envelope as Istanbul.

For system architecture reasons, AMD's MCM picture is a little more complex than was Intel's, because each Istanbul chip has its own on-die dual-channel DDR3 memory controller, along with four HyperTransport links. Obviously, you can't push each chip's full interconnect bandwidth through a single socket, so AMD had to cut out some links.

The company's MCM 2.0 design has four total HT ports (two per chip) and four DDR3 memory ports (two per chip) on each MCM. For each individual chip, one of the links is x16 and another is x8. The two chips are connected inside the module by a x16 HT link.

Even with four HT links and four memory channels to keep the MCM fed, 12 cores is still a lot to pack into a single socket, and bandwidth starvation is a concern. To help alleviate the bandwidth pressure AMD's Istanbul made a very smart tradeoff in the form of HT Assist, and this tradeoff is carried over to Magny-Cours, where it's even more necessary.

One of the big challenges in multiprocessor system design is keeping the various processors' caches in sync with one another; solutions to this problem all involve some amount of communication among the processors, and this "snoop" traffic eats up valuable bus bandwidth. The solution that AMD has adopted with Istanbul and Magny-Cours involves setting aside 1MB of each chip's 6MB cache to store a directory of the contents of the other chips' caches, so that by consulting this local directory each chip can avoid broadcasting a significant number of traffic-increasing snoop requests to the other chips. more

iPhone not exclusive in China, talks with China Mobile go on

noreply@blogger.com (Vash) — Wed, 02 Sep 2009 13:46:00 +0000

The three-year deal Apple made with China Unicom is not an exclusive one, and negotiations continue with China Mobile. Still, regulatory hurdles may prevent Apple from launching a Chinese App Store.

Apple has confirmed that its agreement to sell iPhones via China Unicom, which lasts for three years, isn't exclusive. China Mobile says it is still in talks with Apple to carry the iPhone, though Apple hasn't said what Chinese carriers it is in talks with. And while that company—China's largest mobile carrier by a wide margin—cited control issues with how the App Store is run, there may be further legal hurdles to cross before Apple can offer apps via the App Store to Chinese users. more

Nokia Enters Netbook Market

Linked by Thom Holwerda on Mon 24th Aug 2009 18:44 UTC

In what can surely be called a surprise move, Nokia has announced that it will enter the netbook market with an Atom-based netbook which will ship with Windows 7. While many of the components appear relatively normal compared to other netbooks, it does come with a few features that will set the device apart from the rest. Instant update: Ars believes this is the first Intel Pine Trail netbook.

RAM

noreply@blogger.com (Vash) — Fri, 14 Aug 2009 14:48:00 +0000

RAM: Random Access Memory

SDRAM (Synchronous DRAM)

Almost all systems used to ship with 3.3 volt, 168-pin SDRAM DIMMs. SDRAM is not an extension of older EDO DRAM but a new type of DRAM altogether. SDRAM started out running at 66 MHz, while older fast page mode DRAM and EDO max out at 50 MHz. SDRAM is able to scale to 133 MHz (PC133) officially, and unofficially up to 180MHz or higher. As processors get faster, new generations of memory such as DDR and RDRAM are required to get proper performance.

DDR (Double Data Rate SDRAM)
DDR basically doubles the rate of data transfer of standard SDRAM by transferring data on the up and down tick of a clock cycle. DDR memory operating at 333MHz actually operates at 166MHz * 2 (aka PC333 / PC2700) or 133MHz*2 (PC266 / PC2100). DDR is a 2.5 volt technology that uses 184 pins in its DIMMs. It is incompatible with SDRAM physically, but uses a similar parallel bus, making it easier to implement than RDRAM, which is a different technology.

Rambus DRAM (RDRAM)
Despite it's higher price, Intel has given RDRAM it's blessing for the consumer market, and it will be the sole choice of memory for Intel's Pentium 4. RDRAM is a serial memory technology that arrived in three flavors, PC600, PC700, and PC800. PC800 RDRAM has double the maximum throughput of old PC100 SDRAM, but a higher latency. RDRAM designs with multiple channels, such as those in Pentium 4 motherboards, are currently at the top of the heap in memory throughput, especially when paired with PC1066 RDRAM memory.

DIMMs vs. RIMMs
DRAM comes in two major form factors: DIMMs and RIMMS.

DIMMs are 64-bit components, but if used in a motherboard with a dual-channel configuration (like with an Nvidia nForce chipset) you must pair them to get maximum performance. So far there aren't many DDR chipset that use dual-channels. Typically, if you want to add 512 MB of DIMM memory to your machine, you just pop in a 512 MB DIMM if you've got an available slot. DIMMs for SDRAM and DDR are different, and not physically compatible. SDRAM DIMMs have 168-pins and run at 3.3 volts, while DDR DIMMs have 184-pins and run at 2.5 volts.

RIMMs use only a 16-bit interface but run at higher speeds than DDR. To get maximum performance, Intel RDRAM chipsets require the use of RIMMs in pairs over a dual-channel 32-bit interface. You have to plan more when upgrading and purchasing RDRAM.

From the top: SIMM, DIMM and SODIMM memory modules

Memory Speed
SDRAM initially shipped at a speed of 66MHz. As memory buses got faster, it was pumped up to 100MHz, and then 133MHz. The speed grades are referred to as PC66 (unofficially), PC100 and PC133 SDRAM respectively. Some manufacturers are shipping a PC150 speed grade. However, this is an unofficial speed rating, and of little use unless you plan to overclock your system.

DDR comes in PC1600, PC2100, PC2700 and PC3200 DIMMs. A PC1600 DIMM is made up of PC200 DDR chips, while a PC2100 DIMM is made up of PC266 chips. PC2700 uses PC333 DDR chips and PC3200 uses PC400 chips that haven't gained widespread support. Go for PC2700 DDR. It is about the cost of PC2100 memory and will give you better performance.

RDRAM comes in PC600, PC700, PC800 and PC1066 speeds. Go for PC1066 RDRAM if you can find it. If you can't, PC800 RDRAM is widely available.

Older memory types
Fast Page Mode DRAM
Fast Page Mode DRAM is plain old DRAM as we once knew it. The problem with standard DRAM was that it maxes out at about 50 MHz.

EDO DRAM
EDO DRAM gave people up to 5% system performance increase over DRAM. EDO DRAM is like FPM DRAM with some cache built into the chip. Like FPM DRAM, EDO DRAM maxes out at about 50 MHz. Early on, some system makers claimed that if you used EDO DRAM you didn't need L2 cache in your computer to get decent performance. They were wrong. It turns out that EDO DRAM works along with L2 cache to make things even faster, but if you lose the L2 cache, you lose a lot of speed.

How Much Computer Memory Do You Need?

noreply@blogger.com (Vash) — Fri, 14 Aug 2009 14:41:00 +0000

The easiest ways to boost performance for any PC is to add memory (RAM) to the system. Before purchasing that memory upgrade, however, remember to verify what type of memory your computer uses, the memory module sizes and what already exists in the system. If you are buying a new system, look for the maximum RAM available.

To give you some idea of RAM requirements, according to a 2009 www.pcstats.com article, Windows Vista Basic requires a minimum of 512MB, though they advise that realistically, that number should be doubled.

No need to spend money on extra RAM that your system cannot utilize. You can easily check the specifications of the system you are considering by asking how much memory is already installed, and what the maximum memory capacity is for the system.

When buying a computer or laptop, the available memory on that system should be a primary consideration, because the more you do, the more memory you need! The applications you use dictate how much memory you need for the best possible performance, the smoothest graphics and the speediest downloads.

RAM is used every time you open an application, download, play a game or video – even turning on your computer requires RAM. Peripherals such as webcams, digital cameras, DVD players and USB harddrives require more RAM. These requirements, coupled with complicated web pages and PC-based video games may surprise you in that you have significantly less RAM than you thought. Therefore, buy the most RAM you can afford; more RAM makes for a speedier computer. Today, available PC systems range from 512MB (which is the bare minimum) to 4GB of memory.

If you already have a computer and are considering a memory upgrade, review the manuals that came with your computer or motherboard. Included in the documentation are the specifications for the memory supported. This is important because it will list exactly the type, size and number of memory modules that are supported.

The Different Computer Problems And The Ways To Avoid Them

noreply@blogger.com (Vash) — Fri, 14 Aug 2009 14:24:00 +0000

Slowing down of processing speed - lack of maintenance
Computers need to be regularly checked and maintained for corrupted registry, spyware, and loading of unnecessary programs that eat much of your pc's memory.

Increasing the running time of your computer may involve cleaning up its registry and managing the programs.

Frozen screens are another annoyance. Imagine doing something important and then the computer suddenly stops responding. While this problem may not be easy to diagnose, spyware or virus may be responsible for this. Updating your anti-spyware software is one way to prevent this problem.

Computer virus protection is another extremely useful feature of most computers. This software detects and eliminates computer viruses that may attack your system. Thus, it prevents possible computer virus induced damage.

If no virus or spyware is found, or if they are checked and fixed, and still your pc unit freezes, then check if you have updated your hardware drives. Another cause may be insufficient memory. Thus, upgrading the RAM is another solution to increase computer power.

On some instances, your pc keeps rebooting repeatedly. This is mainly a hard drive problem. Check the power supply in this case. If the cooling fan of your pc does not work properly, your computer may reboot unexpectedly. Dust accumulation in your unit may cause build up of heat that leads to computer failure.

Other components may be subject to occasional failures. For instance, printers may not print. In this case, check power supply and connections. If it is loosely connected to the unit then that may be the problem. Jammed paper inside the printer may also be a culprit. Check printer settings. In some instances, you may need to install the printer software again.

The bottom line of this is basically maintenance of your computer because this is the way to keep it working properly for long. However, you may quite benefit well with computer disaster recovery to back up files and data so everything is secure during emergency cases.
