Whether you’re buying a new laptop or desktop, it pays to do your homework and know what to look for. In addition, it’s important to find the right computer for your needs at the right price.

The processor is one of the most important factors you should consider. It’s the brain of your computer, and it handles a lot of different tasks and information.

Processor

The processor, also known as the Central Processing Unit (CPU), is arguably the most important piece of hardware in any modern computer. The system’s brain interprets instructions, allowing your computer to run programs.

Processors are typically found in desktop and laptop computers and mobile devices like phones and tablets. They take instructions from a computer’s Random Access Memory (RAM) and decode them into signals that control other CPU components.

A CPU may have multiple cores, which enable it to process more than one task at a time. However, more cores aren’t always better – it’s important to know how many cores your specific computer will need before purchasing a new CPU. Check out Canada Computers.

RAM

RAM is a computer component that helps keep your device working as quickly as possible. It enables you to access the data your applications and operating system need at any given time.

This is important because it prevents the CPU from going through slower storage — like your hard drive — each time you need a new browser tab or load a game.

There are three main types of random-access memory, Static RAM (SRAM), Dynamic RAM (DRAM) and Synchronous Dynamic RAM (SDRAM). SRAM uses six transistors to store data without needing capacitors, while DRAM and SDRAM use a combination of transistors and capacitors to store data.

Hard Drive

Your computer’s hard drive stores the operating system, applications and data files such as documents, pictures and music that your computer uses. A hard drive is an electro-mechanical storage device that uses rotating platters and an accuator arm to read and write data. The drive can be external or internal.

Hard drives come in various sizes, including 3.5″ for desktop computers and 2.5″ for laptops. They also come in capacities of several gigabytes and terabytes.

Graphics Card

The graphics card is an essential part of your computer and is responsible for rendering images on your screen. It can be used for anything from photos and videos to games and your normal desktop environment.

The card has a graphics processing unit (GPU) designed specifically for the complex mathematical and geometric calculations necessary for displaying images. These GPUs can handle floating point calculations at very high speeds, sometimes faster than a CPU.

Graphics cards also carry a piece of video RAM, called VRAM, that is used to store data the GPU is working on. This allows the card to process images quickly and efficiently.

Operating System

An operating system is a program that controls all of the hardware and software on a computer. It manages a computer’s resources, provides common services for applications and ensures that the applications and software on a computer work together correctly.

An operating system is vital for any computer, whether a desktop or laptop because it allows you to communicate with the computer without knowing its machine language. This makes it possible for many people to use computers and get things done.

Warranty

A warranty is a guarantee from the manufacturer or seller that they will stand behind their product and fix any issues you may have. This type of warranty can cover a lot or just a little, so it’s important to read the details before you buy.

A computer warranty will often include the model and manufacture of the computer, as well as what parts are covered and excluded from the warranty. It’s important to read it carefully because even small actions on your part can void the warranty.
