Everything You Need to Know about the 2009 Apple MacBook

Portable computers give you the option of working anywhere even if there is no external power source around. Not only can these computers be used to get some work done, but they also can let you watch movies, edit photos, or even play games when you have some downtime. Apple MacBooks are an option for those who may travel or who may need a computer with portability.

What are the 2009 versions of the MacBook?

There were three versions of the MacBook that were released throughout 2009. While all three versions have some similarities, like a separate NVIDIA GeForce 9400M graphics processor and a 13-inch screen with a glossy display, there are some differences. They are

• The early 2009 version: This version has an Intel Core 2 Duo processor that runs at 2.0 GHz. It has 120 GB of storage and 2 GB of 667 MHz DDR2 SDRAM installed in two modules.
• The mid 2009 version: This version has an Intel Core 2 Duo processor that runs at 2.13 GHz. It has a white polycarbonate case. It also features 160 GB of storage and 2 GB of 800 MHz DDR2 SDRAM.
• The late 2009 version: This version has an Intel Core 2 Duo processor that runs at 2.26 GHz, making it the fastest of the three models. It also has a 250GB hard drive and 2 GB of 1066 MHz DDR3 SDRAM that is installed in two modules. This version features a white unibody-style case.

What are the differences between DDR2 and DDR3?

These are two types of random access memory that act as the computer's working memory and as temporary storage. The more RAM a computer has, the more information it can work with at once. DDR2 RAM and DDR3 RAM both work similarly though the latter is capable of transferring data up to twice as fast while using about 30% less power than the former.

What is a unibody?

The late 2009 MacBook was the first of its kind to feature the unibody design that was made from a combination of a polycarbonate or plastic and fiberglass. The entire outer case of the Apple laptop, including the trackpad, the screen enclosure, and the keyboard base, is molded out of the same piece of plastic. Laptops made with this type of case tend to be more durable as the case has less flex than standard portable computers.

What connectivity options does the 2009 MacBook have?

This Apple MacBook series provides a number of options when it comes to connecting to the internet or to other devices. While there may be some minor differences between the versions in this series, all of the laptops feature 802.11a/b/g/n wireless capabilities, several USB 2.0 ports, digital audio and video capabilities, and gigabit Ethernet. The early and mid-2009 models also have a FireWire 400 port.
