Computer hardware refers to the physical components of a computer system, such as the processor, memory, storage, and input/output devices. These components work together to perform the functions of the computer and allow it to process and store data.
The central processing unit (CPU), or processor, is the brain of the computer. It is responsible for executing instructions and performing the calculations that are needed to run the programs on the computer. The CPU is a microprocessor, which is a small chip that contains millions of transistors that perform the calculations needed to execute instructions.
Memory, also known as RAM (random access memory), is the part of the computer that stores data and programs while they are being used by the CPU. Memory is volatile, which means that it is erased when the computer is turned off. There are two types of memory: dynamic RAM (DRAM), which is used for main memory, and static RAM (SRAM), which is used for cache memory.
Storage, also known as the hard drive or solid state drive (SSD), is the part of the computer that stores data and programs permanently. Storage is non-volatile, which means that it retains data even when the computer is turned off. There are two types of storage: hard disk drives (HDD), which use spinning disks to store data, and SSDs, which use memory chips to store data.
Input/output (I/O) devices are the parts of the computer that allow it to communicate with the outside world. Examples of I/O devices include the keyboard, mouse, monitor, printer, and scanner.
In addition to these components, a computer system may also include other hardware components, such as a graphics card, sound card, and network card. These components are responsible for specific functions, such as displaying graphics, playing audio, and connecting to the Internet.
Overall, the hardware components of a computer work together to perform the functions of the computer and allow it to process and store data. They are an essential part of any computer system.
MAIN COMPONENTS OF A COMPUTER HARDWARE
Any organization that uses technology and computers has to have a basic understanding of the parts of the computer hardware they are employing. Without the right hardware, your software could not run at all, let alone effectively. It’s critical to be knowledgeable about the equipment used by your company because it has a significant impact on production.
A computer system consists of numerous parts, like Keyboard, Mouse, Motherboard, CPU, RAM, Monitors, speakers, graphics cards, hard disk, microphone. We’ll go over a few computer parts that affect a computer system’s effectiveness and speed in order to help you choose when you’re ready to acquire one.
1. CPU (Central Processing Unit)
Essentially, a computer’s driver is the processor. Processors are typically distinguished by their speed, expressed in GigaHertz (GHz). The higher the GHz, the faster the computer.
Although you should purchase the quickest processor you can afford, most business tasks, like as checking emails, working on spreadsheets etc, can typically be completed efficiently on a CPU operating at 2 GHz or more. Heavier programs like video editors might require more cores and higher speeds. So it all depends on the needs of a person or business.
You must have heard about Intel Core i3, i5, i7 or i9. Most personal computers are shipped with these intel CPUs. Intel Core i3 processors are dual-core processors (2 cores), while i5 and i7 chips are quad-core(4 cores). Intel Core i7 processors are faster than Intel Core i5, which are faster than Intel Core i3 processors.
Other than Intel processors, the other common manufacturer is AMD.
2. RAM (Random Access Memory)
RAM is a temporary storage location for data while it is actively being used by programs.
Generally speaking, your computer will perform better when running multiple apps at once if yu have more RAM. The amount of RAM in your computer should be sufficient to fully utilize the CPU speed. You need at minimum 4 GB of RAM to properly use numerous modern software programs, and 8 GB or more is ideal for memory-intensive programs like video editing.
3. Hard disk
Hard drives are data storage devices that are used on computer systems to store files, programs, and other information.
The hard disk space on a typical office computer will be at least 320GB or more. Solid state drives (SSD) are standard in most new laptops and high-end computers. These drives are silent due to the lack of moving parts, and they are five to eight times faster than standard magnetic hard disk drives found in most desktop computers.
Although SSD can provide noticeable performance benefits, the price of storage can be two or three times higher for the same amount of storage. Given the performance benefit compared to the overall cost of a standard desktop or laptop, having an SSD is usually the wisest course of action, even with a price premium for one
CHOOSING COMPUTER HARDWARE
There are several factors to consider when choosing computer hardware:
- Performance: The performance of the hardware, including the speed of the processor and the amount of memory and storage, is an important factor to consider. Higher performance hardware can handle more complex tasks and processes data more quickly.
- Compatibility: It is important to ensure that the hardware is compatible with the operating system and any other software that will be used on the computer.
- Price: The price of the hardware is an important factor to consider, especially if you are on a budget. It is important to find a balance between price and performance.
- Reliability: The reliability of the hardware is important, as faulty or unreliable hardware can cause problems and disrupt the operation of the computer.
- Brand reputation: It is helpful to research the reputation of the brand and read reviews from other users to get an idea of the quality and reliability of the hardware.
- Upgradeability: It is important to consider the ability to upgrade the hardware in the future. For example, can the memory or storage be upgraded, or will it be necessary to purchase a new computer to get more performance?
- Size and weight: The size and weight of the hardware may be important if you plan to take the computer with you or have limited space.
Overall, it is important to carefully consider these factors when choosing computer hardware to ensure that you get the right hardware for your needs and budget.
