A Beginner’s Guide to Computer Hardware


Hardware is that part of a PC or laptop which generally performs an essential function. Hardware is divided into three categories, such as applications, user-level software and devices. Computer hardware comprises the basic elements of a PC or laptop, including the case, processor, main board, hard disk, random-access memory (RAM) and computer input/output device (USB). In brief, computer hardware comprises the three major components required in a computing system.

There are two reasons why a user could want to upgrade their computer hardware. The first reason is to get faster speed. Upgraded hardware typically increases the throughput of the CPU and improves the speed of random access memory (RAM) transfer, making the PC or laptop more efficient. Secondly, the user could want to upgrade the hardware to extend the life of the hard drive. Hard drives have a lifespan of ten years, so replacing the hard drive regularly can save the user money over the course of the computer’s lifetime.

There are many more reasons to update your computer system. Perhaps you will want to replace damaged hardware. In this case, you will need to find a manufacturer that produces quality replacement parts. You will also need to update your software so that it takes advantage of newer technology. In most cases, the common types of software that a person may use with their personal computer system are the ones that were installed when the PC or laptop was purchased.

When upgrading the computer hardware, you will need to identify the hardware you currently have and the components of the computer system that you want to upgrade. For example, you may have an AMD Athlon processors, but you no longer use all of the cores. In this case, you will need to identify the parts that you want to upgrade and buy those. It is also important to remember that your memory size and speed will play a part in how quickly your computer operates. Other upgrades will include things such as the video card and hard drives. Upgrading these components can improve the performance of your PC without spending a lot of extra money.

Network cards make it possible for your computer to connect to other computers. In order to edit source code or install third party software, you will need to have a network card. The prices of network cards vary depending on the manufacturer. Some manufacturers make several different models to accommodate personal needs. You can save quite a bit of money by upgrading your existing network cards.

One important piece of computer hardware that should always be upgraded is the monitor. The price of a monitor will vary widely depending on the brand name and the model. You can save a significant amount of money by upgrading to a higher-end model. Upgrading the monitor will enable you to view graphics at a greater resolution and provide better color reproduction.
