My Computer Hardware
Have you ever wondered how my computer hardware works? So many intricate electrical components work together to give you access to today's technical marvels, like computer software and the Internet. Today, we're going to look at four key components of your computer's hardware. To do that, we'll have to go inside your computer
Examples of My Computer Hardware are the following −
- Input devices − keyboard, mouse, etc.
- Output devices − printer, monitor, etc.
- Secondary storage devices − Hard disk, CD, DVD, etc.
- Internal components − CPU, motherboard, RAM, etc.
What's Inside My Computer?
If we removed the tiny screws to open up your PC, you'd see something like the photograph below. Look for the item that's labeled the motherboard (it's the rectangle outlined in white at the lower left). While its appearance seems unassuming, the motherboard is incredibly important. It's a printed circuit board that serves as the foundation of your computer. It allows the CPU, RAM, hard disk drive, and all the other hardware components to communicate with each other. Many people call the motherboard "the heart of a computer."
Next, the CPU (Central Processing Unit) in my computer hardware is known as a microprocessor. It processes instructions gathered from the code in programs and other files. A CPU has four primary functions: fetch, decode, execute, and write back. The computer's CPU is responsible for handling all instructions received from hardware and software running on the computer. It's basically the brains of the operation. The CPU also has a cooler, comprised of a heat sink and a fan. Considering its size (maybe as big as a fingernail, and new ones are getting smaller every day), it's amazing that, if not properly and regularly cooled, it can generate enough heat to melt within minutes. You can see the CPU labeled in the photo above.
Different Types Of Computer Hardware
- 4 GB of RAM: If you’re only browsing the web, working with basic Office applications and maybe dabbling a bit in personal photo editing, you’ll be fine with 4 GB of memory.
- 8 GB of RAM: Heavy multitaskers or light gamers should choose a computer with 8 GB of RAM.
- 16+ GB of RAM: Some tasks are inherently computing intensive, such as serious gaming, video editing, and programming. “Enthusiast” users who never want to experience slowdowns will need 16+ GB of RAM to be happy.
- One of the significant advantages of a Hard Disk drive is that its cost is low.
- Another advantage of a Hard Disk is that it is readily available in the market.
- Hard Disk is faster than optical disks.
- The capacity for storing the data in HDDs is large.
- Display module: Often the type that uses thin film transistor liquid crystal display (TFT-LCD) technology
- Casing or cover
- Cathode Ray Tube (CRT) monitor
- Liquid Crystal Display (LCD) monitor
- CPU is considered as the brain of the computer.
- CPU performs all types of data processing operations.
- It stores data, intermediate results, and instructions (program).
- It controls the operation of all parts of the computer.
- Memory or Storage Unit
- Control Unit
- ALU(Arithmetic Logic Unit)
RAM (Random Access Memory) is a type of computer hardware that is used to store the information and then process that information. The processing speed of RAM is much faster than a hard disk but Ram is a volatile device which means when a computer system is shut down all the information stored is wiped out from RAM whereas hard disk is non-volatile which means it stores the data permanently in it. RAM is temporary storage that goes away when the power turns off. So what is RAM used for, then? It’s very fast, which makes it ideal for things the computer is actively working on, such as applications that are currently running (for example, the web browser in which you’re reading this article) and the data those applications work on or with. Here are our recommendations, which apply to any operating system or personal computer hardware:
A hard disk is also known as a hard drive or fixed disk. It is said to be rigid magnetic disc that stores data. It is located within a drive unit. Hard disk is a non-volatile storage device that contains platters and magnetic disks rotating at high speeds. Non-volatile means the data retains when the computer shuts down.It is installed internally in our computer systems. Hard disk is located within a drive unit on the computer's motherboard and comprises one or more platters packed in an air-sealed casing.
Its main components include a read/write actuator arm, head actuator, read/write head, spindle, and platter. A circuit board (also called as the interface board or disk controller) is present on the back of a hard drive. It lets the hard drive to communicate with the computer.
It is another type of computer hardware that is used to store the data in it. The hard disk can be preinstalled in CPU or can be used as an external device. The hard disk is the non-volatile component which means the data is stored permanently in hard disk and it does not wipe out when the system is shut down.

A monitor is an electronic device used to display video output from a computer. Screen monitors are used in many computer devices, from personal computers (PCs) and laptops to small mobile devices, such as cell phones and MP3 players. Monitors are also known as computer screens or display screens. For the computer hardware, the hardware is another device that is used to display the output, videos and other graphics as it is directly connected to the CPU. The video displayed by the monitor uses the video card.The monitor consists of the following components:
Initially, monitors were only found on computer devices. However, as screen technology becomes smaller, cheaper and more powerful, screen monitors are increasingly being added to a variety of devices.Types of Computer Monitors.
CPU (Central processing unit) is the core hardware part of the computer system which is used to interpret and execute most of the commands using other computer parts i.e. software and hardware. The CPU is a core part of any PC, laptops, tablets, and notebooks.The central processing unit runs everything. It fetches program instructions over its “instruction side” (IS) bus, reads data over its “data side” (DS) bus, executes the instructions, and writes the results over the DS bus. The CPU can be clocked by SYSCLK at up to 80 MHz, meaning it can execute one instruction every 12.5 ns. The CPU is capable of multiplying a 32-bit integer by a 16-bit integer in one cycle, or a 32-bit integer by a 32-bit integer in two cycles. There is no floating point unit (FPU), so floating point math is carried out by software algorithms, making floating point operations much slower than integer math. CPU consists of the following features −
CPU itself has following three components.
A computer mouse, as we all know, is an electronic device (which may or may not be wireless) that helps to move the cursor on a computer screen as you move the mouse over a flat surface. So, a mouse essentially calculates how much you move it in a certain direction (in two dimensions) and subsequently feeds the computer that information to allow for comprehensive control of the graphic user interface. There are a number of variants of computer mice, including a mechanical mouse, optical and laser mice, a 3D mouse, inertial and gyroscopic mice, the ergonomic mouse, gaming mice and tactile mice. It is a hand operator input device that is used to point something on the screen. The mouse can be wired or wireless.
How does a mouse work?
When you move the mouse, the ball rolls beneath it, pushing the two plastic wheels/rollers linked to it in the process. One of those wheels detects side-to-side movement (x-axis wheel) and the other (y-axis wheel) detects movement in the up-and-down direction. Both of these wheels consist of spokes that ‘break’ a thin light beam inside the mouse. The number of times the beam breaks helps to calculate how far the mouse has moved.
For instance, when you move the mouse straight up, the y-axis wheel turns. The farther up you go, the more the ball pushes the wheel and the more it breaks the light beam. This helps to determine how far the mouse has moved straight up. Similarly, the mouse uses the x-axis wheel to calculate side-to-side movement. When the mouse is moved at an angle, the calculations obtained from the movement of both of these wheels are used. Mechanical mice were quite popular in the past decade, but due to their clunkier design and relatively lessened durability, they were quickly replaced by optical mice.
Advantages of My Computer Hardware
Following are the advantages pointed below.
- It will help to establish an effective mode of communication that can help the organizations to improve their business standards.
- It will help to make the task automated and help to store the huge chunks of data that can be beneficial for the organization or individual.
- The user can use the hardware to give the instruction to command and can obtain the output as per the given instruction.
- The processing speed of a hardware device is fast which will help to execute more operations at one time.
- The hardware devices are multiprocessing which means the user can use more than one hardware device at the same time.
- The hardware can be installed very easily in a computer system and also can be upgraded as per the user requirements.
What Can Go Wrong With My Computer Hardware?
The parts that most commonly break are fans, hard disk drives, CPUs, and GPUs.
RAM also tends to fail too. It is continually being written and re-written to (flashed). Solid-state memory can only handle so many flashes before it begins to fail. The problem also applies to solid-state hard drives.
The best way to avoid being caught out is to perform regular hardware diagnostic tests on your computer. Here's how to do hardware tests on Windows 10.
How to check My Computer Hardware specifications?
For Windows 10
To check your PC hardware specs, click on the Windows Start button, then click on Settings (the gear icon). In the Settings menu, click on System. Scroll down and click on About. On this screen, you should see specs for your processor, Memory (RAM), and other system info, including Windows version.
For Windows 7
To check your PC hardware specs, from the desktop find the icon that is labeled “My Computer”. Right-click on this and select Properties. A window should appear summarizing your PC hardware specs including processor, Memory (RAM), and other system info, including Windows version.
How to Check What Processor (CPU) You Have ?
If you’re wondering what kind of my computer hardware you have, you can easily find out that information on a Windows 10 computer in two clicks. To find out what CPU you have, simply do the following:
- Right-click on the Windows start menu icon on the bottom left-hand side of your screen.
- Click on ‘System’ in the menu that pops up.
- Next to ‘Processor’ it will list what kind of CPU you have in your computer.
How to Check What Graphics Card (GPU) You Have ?
If you want to find out what kind of graphics card you have in your my computer hardware, the process is similar to finding out what CPU you have, but checking to see what GPU is in your system is 50% more work than checking to see what your CPU is.
- Again, right-click on the Windows start menu icon.
- Click on ‘Device Manager’ in the menu that pops up.
- In ‘Device Manager’ click on the arrow next to ‘Display Adapters’
- Your GPU will be listed there.
