Chapter 2: 

What is computer hardware? Write the types of hardware with example.    

Answer: Hardware: Computer system is made up of a combination of hardware and software Different parts of a computer are called Hardware. We can touch and feel hardware. By touching it, we can feel its presence. But, hardware cannot run alone.

There are three types of computer hardware: (1) Input device: keyboard, Mouse, etc. (2) Processing unit: All Unit, Ram, Rom, Mother board etc. (3) Output device: Monitor, printer, etc.

Internal Hardware: CD-ROM and DVD, Hard Drive, Motherboard, Ram, Sound Card, Video Card.

External Hardware: Monitor, LCD, Keyboard, Mouse, Printer, and Scanner.

 

What are the physical and logical components of a personal computer (PC).

Answer: Computers are complex machines that appear to be very intelligent but in reality, are only very fast. Six essential components provide the various capabilities that a computer needs to do its job and appear to be so smart.

Physical and logical components:

1.       Motherboard.

2.       Processor/CPU.

3.       Power Supply.

4.       Hard Drive.

5.       PCI-Express Cards.

6.       Graphics Cards.

7.       RAM/Memory.

What is CPU? Write the components of CPU.

Answer: The CPU is the heart and brain of a computer. It receives data input, executes instructions, and processes information. It communicates with input/output (I/O) devices, which send and receive data to and from the CPU. Additionally, the CPU has an internal bus for communication with the internal cache

memory, called the backside bus. The main bus for data transfer to and from the CPU, memory, chipset, and AGP socket is called the front-side bus.

The CPU has three components:

1. Control Unit: Extracts instructions from memory and decodes and executes them.

2. Arithmetic Logic Unit (ALU): Handles arithmetic and logical operations.

3. Memory Unit: Memory unit is the amount of data that can be stored in the storage unit.

Need to understand what equipment is in your computer? Become a computer genius with our speedy manual for these fundamental parts and their jobs.

Simply, computer equipment is the actual parts that a computer system needs to work. It envelops everything with a circuit board that works inside a PC or laptop; including the motherboard, illustrations card, CPU (Central Processing Unit), ventilation fans, webcam, power supply, etc.

In spite of the fact that the plan of equipment contrasts between work area PCs and laptops because of their disparities in size, similar center segments will be found in both. Without equipment, there would be no chance to get of running the basic programming that makes computers so helpful. Programming is characterized as the virtual projects that sudden spike in demand for your computer; that is, working system, web program, word-preparing archives, and so on

Albeit a computer can work just when both equipment and programming are cooperating, the speed of a system will to a great extent depend on the equipment utilized.

When developing another computer, or basically supplanting old parts, you may have to know the particular equipment in your computer. The motivation behind this guide is along these lines to assist you with understanding the inward functions of your computer.


What is a Motherboard?

The motherboard is at the focal point of what makes a PC work. It houses the CPU and is a center that any remaining equipment goes through. The motherboard goes about as a mind; apportioning power where it's required, speaking with and planning across any remaining segments – making it one of the main bits of equipment in a computer.

While picking a motherboard, it's critical to check what equipment ports the motherboard supplies. It's fundamental to check the number of USB ports, and what grade (USB 2.0, 3.0, 3.1) they are, just as what show ports are utilized (HDMI, DVI, RGB) and the number of each there are. The ports on the motherboard will likewise assist you with characterizing what other equipment will be viable with your computer, for example, what kind of RAM and designs card you can utilize.

Despite the fact that the motherboard is only one bit of hardware, it is home to another of the main bits of equipment: the processor.

What is a CPU (Central Processing/Processor Unit)?

The CPU (Central Processing Unit or processor) is liable for handling all data from programs run by your computer. The 'clock speed', or the speed at which the processor measures data, is estimated in gigahertz (GHz). This implies that a processor promoting a high GHz rating will probably perform quicker than a likewise indicated processor of a similar brand and age.

What is RAM?

Arbitrary Access Memory, or RAM, is equipment found in the memory openings of the motherboard. The function of RAM is to incidentally store on-the-fly data made by programs and to do as such that makes this information quickly available. The assignments that require irregular memory could be; delivering pictures for visual depiction, altered video or photos, performing various tasks with numerous applications open (for instance, running a game on one screen and visiting by means of Discord on the other).

The amount RAM you require relies upon the projects that you'll be running. Medium force gaming for the most part utilizes 8GB of memory when performed close by different projects, however video/visual depiction can utilize as much as 16GB of RAM. Discover how much memory your computer needs.

What is a Hard Drive?

A hard drive is a capacity gadget liable for putting away perpetual and impermanent information. This information comes in various structures, yet is basically anything saved or introduced to a computer: for instance, computer programs, family photographs, working system, word-preparing records, etc. Discover more about hard drives and how they work. 

There are two distinct sorts of capacity gadgets: the conventional hard plate drive (HDD) and the fresher strong state drives (SSD). Hard circle drives work by composing double information onto turning attractive plates considered platters that pivot at high speeds, while a strong state drive stores information by utilizing static blaze memory chips. Discover more about computer stockpiling and how strong state drives work.

What is a Graphics Processing Unit (GPU)? 

Particularly significant for 3D delivery, the GPU does precisely what its name recommends and measures tremendous groups of realistic information. You will find that your computer's designs card has at any rate one GPU. Instead of the essential onboard realistic capacities that PC motherboards supply, committed design cards to interface with the motherboard by means of an extension space to work solely on realistic delivering. This likewise implies you can update your design card on the off chance that you need to get a touch more execution from your PC. 

This, yet current GPUs satisfy an expansive computational outstanding burden past delivering, making them an augmentation to the focal preparing unit.

What is the Power Supply Unit (PSU)? 

A force supply unit generally contracted as PSU accomplishes something beyond supply your computer with power. It is where force enters your system from an outside force source and is then apportioned by the motherboard to singular part equipment. Not all force supplies are made similarly in any case, and without the correct wattage PSU your system will neglect to work. 

A cutting edge computer will, by and large, need a PSU that is evaluated between 500W – 850W to viably control all equipment, in spite of the fact that the size of the PSU will rely completely upon the force utilization of the system. Computers that are utilized for profoundly escalated assignments, for example, visual depiction or gaming will require all the more impressive segments and along these lines will require a greater PSU to take into account this extra need. 

Without the perfect measure of intensity, parts won't have the option to run adequately and the computer may encounter crashes or just neglect to boot by any means. It's prescribed to have a force supply that more than covers your system use. In addition to the fact that you guard yourself against system disappointment, you likewise future-verification yourself against requiring another PSU when you move up to all the more remarkable PC parts. 

Understanding your computer and its equipment segments can demonstrate extremely helpful when the opportunity arrives to redesign or supplant any parts, or when fabricating a computer. Should an issue emerge with the inward operations of your computer, you will have a superior comprehension of the significance of every part, the requirement for them to be in acceptable working condition and how to approach settling any issues.
