Computers
a) Speed b) Cache c) No. of cores (dual core, quad core etc.)
These should be given high priority if you are going to run highly complex applications which will require more speed and short term usage during processing (provided by Cache).
Random Access Memory (RAM): The higher the RAM the faster your machine will be in supporting multiple applications. For example, if someone wants to run Windows XP and Vista he will need a minimum of 256 and 512 MB of RAM respectively.
Hard Drive: The hard drive is where your data and files are stored. Most hard drives are now quite large at 100GB - 300GB or more. You might also want to check the rotational speed - a 7,200rpm hard drive is faster than a 5,400rpm model. How fast the disk spins will also determine the performance level of your computer or laptop.
Optical Drives: These are removable drives that write and read data using lasers. Common ones include CD ROM, DVD ROM, CD R/RW and DVD R/RW drives. The speed at which these optical drives work is measured in “150kb per second” units. Factors of “x” are used such as 4X, 8X... remember that DVD drives can use both DVDs and CDs.
Ethernet Port: This lets you connect your computer to a wired Ethernet network (Group of computers working together.)
Integrated Bluetooth:
Bluetooth is a standard wireless networking system which lets you connect wirelessly to your computer’s peripherals such as mouse, keyboards, headsets, printers.
Integrated Wi-Fi:
Integrated Wi-Fi gives you wireless network access.
Other technical feature will include dedicated video memory, graphics card, sound blaster, webcam, microphone which will depend on very specific requirements.
Other than technical details another thing to look at is Warranty like one does with any other product.
