Enhance your information about MAC OS.

                                      MAC OS-----

Mac OS is a series of GUI based OS developed by APPLE inc. (formerly Apple Computer, Inc.) for their macintosh line of computer system. The Macintosh user experience is credited with popularizing the graphical user interface. The original form of what Apple would later name the "Mac OS" was the integral and unnamed system software first introduced in 1984 with the original macintosh, usually referred to simply as the System software  
From the beginning, Apple deliberately sought to as minimize by design the user's conceptual awareness of the operating system as such. Tasks that on other products required a more explicit working knowledge of an operating system would on a Macintosh be accomplished by intuitive mouse gestures and manipulation of graphical control panels. The intention was that the product would thus be more user friendly and so more easily mastered. This would differentiate it from devices using other operating environments, such as MS DOS machines, which were more technically challenging to operate.


         MAC OS X- 

Mac OS X is the newest of Apple inc. Mac OS line of operating systems. Although it is officially designated as simply "version 10" of the Mac OS, it has a history largely independent of the earlier Mac OS releases.

The operating system is the successor to MAC OS 9 and the "classic" Mac OS. It is a Unix operating system, based on the NeXTSTEP operating system and the Mach Kernal which Apple acquired after purchasing NeXT Computer, with its CEO Steve jobs returning to Apple at this time. Mac OS X also makes use of the BSD code base. There have been six significant releases of the client version, the most recent being Mac OS X 10.7, referred to as Lion. On Apple's October 20th 2010 "Back to the Mac" event, Mac OS X 10.7 Lion was previewed, showing improvements and additions including a Mac App Store.

As well as the client versions, Mac OS X has also had six significant releases as a server version, called Mac OS X Server. The first of these, MAC OS X server 0.9, was released in beta in 1999. The server versions are architecturally identical to the client versions, with the differentiation found in their inclusion of tools for server management, including tools for managing Mac OS X-based workgroups, mail servers, and web servers, amongst other tools. It was the default operating system for Xserve(which has now been discontinued), it's an optional feature on the Mac Mini and the Mac Pro, and it's also installable on most other Macs.

Mac OS X is also the basis for IOS, (previously iPhone OS) used on Apple's iPhone, iPod touch, and iPad...

                                                             make a right choice.

A laptop, also called a notebook, is a personal computer for mobile use. A laptop integrates most of the typical components  of a desktop computer, including a display,a keyboard, a pointing device (a touchpad, also known as a trackpad, and/or a pointing stick) and speakers into a single unit. A laptop is powered by mains electricity via an AC adapter, and can be used away from an outlet using a rechargeable battery  






                                      The basic components of laptops are similar in function to their desktop counterparts, but are miniaturised, adapted to mobile use, and designed for low power consumption. Because of the additional requirements, laptop components are usually of inferior performance compared to similarly priced desktop parts. Furthermore, the design bounds on power, size, and cooling of laptops limit the maximum performance of laptop parts compared to that of desktop components   
                    The following list summarizes the differences and distinguishing features of laptop components in comparison to desktop personal computer parts:---

•  Laptop CPU's have advanced power-saving features and produce less heat than desktop processors, but are not as powerful. There is a wide range of CPU's designed for available from Intel. On the non-x86 architectures, Motorola and IBM produced the chips for the former Power PC-based Apple laptops . Some laptops have removable CPUs, although support by the motherboard may be restricted to the specific models. In other laptops the CPU is soldered on the motherboard and is non-replaceable.
•  SO DIMM memory modules that are usually found in laptops are about half the size of desktop DIMM's. They may be accessible from the bottom of the laptop for ease of upgrading, or placed in locations not intended for user replacement such as between the keyboard and the motherboard. Currently, most midrange laptops are factory equipped with 3–4 GB of DDR2 RAM, while some higher end notebooks feature up to 32 GB of DDR3 memory. Netbooks however, are commonly equipped with only 1 GB of RAM to keep manufacturing costs low.

.

• On standard laptops the video controller is usually integrated into the chipset to conserve power. This tends to limit the use of laptops for gaming and entertainment, two fields which have constantly escalating hardware demands, and because the integrated chipset is very difficult to upgrade for a standard user, laptops may grow obsolete quickly for use in gaming and entertainment

Netbooks  are laptops that are light-weight, economical, energy-efficient and especially suited for wireless communication and Internet access. Hence the name netbook (as "the device excels in web-based computing performance) With primary focus given to web browsing and e-mailing netbooks are intended to "rely heavily on the Internet for remote access to web based applications and are targeted increasingly at cloud computing users who rely on servers and require a less powerful client computing A common distinguishing feature is the lack of optical disk (i.e. CD, DVD or Blu Ray) drives. While the devices range in size from below 5 inches to over 12,most are between 9 and 11 inches (280 mm) and weigh between 0.9–1.4 kg (2–3 pounds).

Netbooks typically have less powerful hardware than larger laptop computers. Some netbooks do not even have a conventional HDD Such netbooks use solid state storage devices instead, as these require less power, are faster, lighter, and generally more shock-resistant, but with much less storage capacity (such as 32, 64, or 128 GB compared to the 100 GB to 2 TB mechanical hard drives typical of many notebooks/laptop computers).All netbooks on the market today support Wi- Fi wireless networking and many can be used on mobile telephone networks with data capability (for example, 3G). Mobile data plans are supplied under contract in the same way as mobile telephones. 

So, Netbooks are used mostly for business purposes while most people switch to laptops...

Donate Blood...be a BLESSING to somebody!

 
                    OCTOBER 1, 2011  - BLOOD DONATION DAY...
Winston Churchill once remarked "we make a living by what we get but we make a life by what we give".
one pint of blood can save upto three lives. Its a remarkable contribution towards the society.put your step forward in this noble task.your initiative can save a precious life.
   facts about blood:

• Blood makes up about 7 percent of your body's weight
• Donors can give either whole blood or specific blood components only. The process of donating specific blood components – red cells, plasma or platelets – is called apheresis.
• Donated platelets must be used within five days of collection.
• Healthy bone marrow makes a constant supply of red cells, plasma and platelets. The body will replenish the elements given during a blood donation – some in a matter of hours and others in a matter of weeks.                                   

Post donation care:

1. Drink plenty of fluids.
2. No extra diet is required.
3. Rest for 10-15 min. after donation.
4. Do not lift heavy objects for few hours.
5. Avoid strenuous exercise for 24 hrs.
6. If bleeding starts again press firmly on that area and raise the arm above the level of heart.

donate blood and feel the happiness...                                                                              source:
