A simple computer buying guide that highlights the basic features of computers in simple English.
When buying a desktop computer one of the first things to look at will be its use and individual budget. For example, a machine that will be primarily used for gaming should focus on lots of memory, a powerful processor, enhanced video and graphics, while a computer that will be used for Internet browsing and simple word processing will not need nearly as much frills. And there are many dell computer models for every type of computer need.
This computer-buying guide covers the basics to give you some idea of the important features to look at.
CPU CPU stands for central processing unit and is the brains of the computer. It is where most of the actual computing takes place and the quality of the processor will greatly determine the performance of the computer. The processor speed is measured in GHz.
There are budget processors, mid grade and high-end processors. The high end ones maybe necessary for enhanced computer functions, such as gaming and entertainment, but overall the mid grade types are quite good and will deliver great performance for most any uses. Overall the two best brand names for processors are Intel and AMD.
RAM Memory RAM memory refers to the amount of programs you can run on computers without running into slow downs in performance and crashes. The more RAM the better, especially for video, entertainment and gaming. 1GB is the absolute minimum for most computer functions on XP, and 3GB is the most a 32 bit computer can address. On 64 bit computers, 4GB is the minimum to look for.
Also, it is a good idea to check and make sure that there are open memory upgrade slots so you can always add more memory as it is fairly cheap and easy to install.
Hard Drives Hard drives are significant for the speed capacity of computers. Overall, the larger the drive the more storage space and the faster the computer. Solid State Drives (SSDs) are incredibly fast and the prices are coming down. They will transform your experience especially with newer motherboards with fast processors.
Optical Drives - CD/DVD/Blu-ray Most computers these days come with DVD/CD burners, and even if they do not they are cheap and easy to install and come in internal and external versions. Blu-ray is the latest option for burning in high definition format.
External Ports and Connections Ports are used to attach peripherals, such as printers, Internet, iPods and others. Most important will be to have at least 5 USB ports, one FireWire port as well as an Ethernet connection for Internet and networking. Overall, the more ports you have the more variety and options will be available to add ons.
Monitors A good monitor is essential for a quality computer experience. The older CRT models are now obsolete with the introduction of LCD screen monitors. LCD screen monitors have a superior display with a reduced size due to the flat panel and their lower power consumption over the CRT models.
They come in a variety of sizes and sometimes the larger ones are a better value for the money and make the best experience for gaming, entertainment, free Web Content, such as video watching, and are much easier on the eyes.
