Buying a Computer System is could be a cheap thing to a person who knows about computer hardware, and a very difficult task to a novice. therefore it is strongly recommended that you know or have a good quality of information about systems before you go to the market to make purchase. You could solicit the help of an expert to help you make the selection. When you want to make use of only the browser and other little things, it is advisable to get a note pad. The first step to take in buying a computer system is to determine whether you will need a desktop or a laptop. The desktop is always cheaper and it is mounted on a point, it cannot be moved around. At the point of purchase it has some additional cost, like buying a monitor and a UPS if it did not come with it as a complete set. On the other hand the laptop has a low or no additional cost at the time of purchase because it is a complete system. When purchasing a laptop you will have to put the battery into consideration because it determines how long your system works before shutting down. you should get a good one that last for at least 3hours.
Here are the basic tips you need to know when buying a computer system:
- Central Processing Unit (CPU): The CPU is the brain of the computer and also determine the speed of the computer. you have to know the stacks of the cores or the speed of the processor which is labeled in GHz or Gigahertz. this will tell how much data the computer can process at a given time. The number of cores functions as a multiplier, as the processor is actually a stack of cores that each run at the listed speed (e.g. a single-core 2GHz processor is a lot slower than a four-core 2GHz processor).
- Random Access Memory(RAM): Just as the CPU contributes to the speed of the system so does the RAM in determining the computer systems speed in multitasking handling. The RAM keeps your information at hand rather than you go looking for it in the hard disk. Rams are measured in Gigabytes.
- Hard disk: The hard disk is where your files and programs will be saved, the content that is on the RAM is also saved there. therefore if you will work with large and heavy files you will need a large size hard disk. Hard disk are measured in Gigabytes e.g 80gigabyte or 80G, 256G, 512G, 1Terabyte,etc
- Peripherals: The peripherals are those points and devices the computer does not really depend on them to function but it helps us to communicate and access data from the computer. in buying a computer system , one has to take note of the Universal serial bus(USB) , Audio ports , WiFi , Network Lan RJ45 plug , VGA. DVD drive, etc. these is to ensure that the best is but and will not hinder your operations and desires.
