Today, computer has become an integral part of our lives. We are dependent on this technological marvel for most of the things. An individual spends most of the part of his day sitting on a computer, either at workplace for productivity, or at home for entertainment. Several types of computers are available in the market today, ranging from palmtops to desktops. Though the latter has been here for a couple of decades now, it is still a favorite when it comes to all round use. Guide to Buy a Computer Some desktop computers have a good data storage capacity, while some have a better RAM. Some sport a sleek design, while some offer loads of extras in terms of features. With all these options available, choosing the one that is ideal for you, is bound to be a tough task. Budget and Usage The foremost thing to asses is your capacity to spend; you surely wouldn't want to overspend on buying a computer, paying extra cash for features which you would never use. The purpose is yet another important aspect. If you just have to check mails or access the Internet for entertainment, even a simple computer will be more than enough. However, if you want a computer to run a web-based business, you will require an advanced computer. A simple computer will cost you less than what its technologically advanced counterpart would. Therefore, depending on the need, you have to decide which PC to buy and how much are you willing to spend. Hard Disk and RAM Yet another crucial aspect you need to consider, is the size of its hard drive, which will indirectly affect its storage capacity. If you plan to store a huge amount of digital data, such as pictures, music, movies, and various software programs, then you will need a hard drive with larger capacity. The RAM (random access memory) of the computer affects its processing speed. Word processing operations require much less RAM than other software programs. Having a good capacity RAM will make sure that your computer works smoothly for a long time. Computer Hardware You can also consider choosing the shape and size of the monitor depending on your usage. Buying wide-screen monitors has become a popular trend today, as the large screen facilitates their use for longer duration without straining the eyes. If you are into multitasking, desktop PC with dual monitor configuration is an ideal choice. Depending on your convenience you can choose keyboard, mouse, connecting cables, and speakers. Ergonomic and wireless models of keyboards and mouse are becoming more and more popular today. Buying a CPU with extra bays can be advantageous, as it will offer you the facility of expanding the computer capability by adding additional drives and ports, instead of going for a new model. Security and Model Reliability If you plan to use your computer for surfing the Internet, you will have to invest some amount in PC security. High quality anti-virus and anti-spyware programs can help you to keep your computer safe from malicious programs. Many companies provide these products on a free-trial basis with a new computer. Buy desktop PC from a reliable dealer and ensure that you have researched well about the product before you buy it. Cross check the documents stating warranty, guarantee, and return policy. Go through customer reviews and queries about the particular model on renowned publications. In the age of technology, computer is an important tool in our day-to-day life, so buying a desktop which is ideal for you and your family will be very important.
