The overall contributions of computers to the home, office, business, and educational institutions cannot be fully appreciated or enumerated owing to their vast quantity. Being very handy and useful pieces of electronics, utmost care and due considerations ought to be taken while acquiring them.
The discussions that follow shall discuss the things to consider while shopping for a new computer:
The Type of Computer
There are two main types of computers in vogue today. These are: The desktops and the laptops respectively. Laptops are generally light in weight, portable and easy to transport around as need be. Desktops on the other hand are intended to stay fixed on one location throughout owing to their bulky size.
It refers to the main purpose for which the computer is to be put into use. If the computer is to be used for field work or in remote locations, then a lighter, compact and durable machine such as a laptop or tablet is to be acquired and in case it is to be used in an office setting, then a desktop would be the better option.
It is basically the “brain” of the computer; which means that it is the logic circuitry which responds to and processes the basic instructions which eventually drive the computer. The quality of a computer’s processor is determined by the amount of data that it can handle at any given time and is denoted in GHz or Gigahertz. The higher the number of GHz, the better, as it implies that the processor allows for multi-tasking of duties. For instance a dual-core 2GHz processor is comparatively slower and less versatile than a four-core 2GHz processor.
Random Access Memory (RAM)
Random Access Memory is the portion of the computer memory where the application programs, operating system, and data that are currently used are stored in order for them to be quickly accessed by the computer’s processor. It is expressed in Bytes, Kilobytes, Megabytes, or Gigabytes. As a general rule, the higher the storage capacity, the better and more reliable the computer is.
The field of computer manufacture is awash with innumerable players each with its own nice of specialization. Hewlett Packard, Toshiba and Acer are particularly famed for producing quality laptops, whereas Dell is generally regarded as an excellent manufacturer of desktops. Priority should therefore go to these brands while making an appropriate selection.
Hard Disk Storage
This is the part of a computer which stores data on an electromagnetically-charged surface and provides quick access to that data if and when need be. This parameter is expressed in Bytes, Kilobytes, Megabytes, or Gigabytes, with the larger the value indicating a superior and more reliable a computer and vice versa.
Peripheral devices are extra gadgets or electronics that are connected to a computer in order to enhance its functionality. They include such gadgets as a mouse, external hard drives, printers, scanners, monitor, flash disks, modems, and so on. The ideal computer must be able to accommodate as many peripheral devices as possible.
It is a measure of how big the screen of a computer is. It is obtained by measuring the distance between the top left portion of the screen and the bottom right portion and is expressed in inches. The choice of the most suitable screen size largely depends on the purpose for which the computer is to be used. The lovers of movies and video shows would thus prefer a large screen as opposed to those who intend to use the computer purely for office work.
This basically refers to the ability of the computer to be interconnected to and communicate with various other devices, systems, platforms, and applications. The main ways through which computers can interconnect and communicate with external devices and platforms include the Wi-Fi, Sync, Bluetooth, and Data Cables. The most suitable computer should be capable of being connected to as many platforms and in as many ways as possible.
Operating system is the software which supports the computer’s basic functions including but not limited to scheduling of tasks, controlling the peripherals and executing commands and applications. The best computer must have the latest operating system software.
No matter how superior, fast and efficient a computer could be, whether or not it will be eventually bought depends largely on its cost. The computer of choice should, in addition to being of highest quality, be as affordable as possible. It should also be ideally accompanied by a manufacturer’s warranty to shield its users from any losses or damages.
Being a complex undertaking, the task of finding the right computer is suitably delegated to a competent Information Technology expert or consultant if the hopes of obtaining the highest quality device is to be realized.
