HELLO WORLD


Computer Hardware and Working


Introduction:

Coumputer hardware has mainly four parts those are

1.cabinet

2.monitor

3.mouse 

4.keyboard

Let us know about each one.....

1.Cabinet: 

 

Cabinet is a outer cover with inside covering of  CPU(Central processing unit),RAM(Ramdom acess memory),Motherboard,Hard disk,Cables,Cpu cooler,Gpu,Lan card,SMPS..............

     These are all placed inside the cabinet with fixed places connected with cables,outside the cabinet we connect pendrive,ethernet cable,connectio to monitor, cpu,keyboard,smps,speakers....and all outputs.

2.Monitor :


Moniter is nothing but screen where we see output of the cpu.We connect moniter cable to the outside of cabinet,we palce this moniter in tabletop for your convinience,there are many sizes of moniters avaible.

3.Mouse :

 

Mouse is a output device for taking input for us.Mouse works with the principal of taking thousands of pictures per second and comparing each picture and take decision process in mouse IC(integrated circuit) this is the working process of mouse.

4.Keyboard :


Keyboard is a output device connected to cabinet,keyboard us using for typing in coumputer.

Let us know deeply for each one......

Cabinet :


There are so many parts inside the cabinet those are CPU,RAM,MOTHER BOARD,SMPS,HARD DISK,CPU COOLER,CABLES.


CPU : cpu means central processing unit,cpu is the brain of the coumputer it process all the data inside the computer.


It plays important role in the coumputer,cpu is the highest cost in coumputer,cpu uses more current than all other parts.Cpu is made up of silicon because TRANSISTOR==CPU.In cpu millions of transistors are placed with very thin transistors ofcourse transistor is build with silicon and berelium,So cpu is made up of silicon or berelium

Make about phone cpu later.....
 

RAM :Ram is nothing but random access memory ,it store data temporarly  untill the power is shutdown like cache memory.Computer random access memory (RAM) is one of the most important components in determining your system’s performance. RAM gives applications a place to store and access data on a short-term basis. It stores the information your computer is actively using so that it can be accessed quickly. The more programs your system is running, the more you’ll need. SSDs (solid state drives) are also important components and will help your system reach its peak performance.

       The speed and performance of your system directly correlate to the amount of RAM you have installed. If your system has too little RAM, it can be slow and sluggish. But on the opposite end, you can install too much with little to no added benefit.

Ram is like friend to cpu for helping and processing data.


'iii'.ROM :Rom means Random access memory, it is used to store information or data or anything what you do in computer.


There are two types of rams

a.HDD (Hard disk drive)

b.SSD (Solid state drive)


a.Hard disk drive(HDD):It is a drive with moving parts in it,hdd has one highly premium drive and a motor to read and write data the disk continously move and read and write data

HDD Cons:It is cheaper than ssd.

HDD Pros:It uses more electricpower than ssd.

It make low noise because moving parts in it.

It is slightly bigger than ssd.

It read and write data slowly.


b.Solid state drive(SSD):It is a memory storing drive to store data and information and things you do in coumputer. it is small and read and write data fast and it gives good performance.

In ssd small memory chips present in it like sd card.


SSD Cons:It uses less electric power.

It has no moving parts so no output noise.

It highly performes read and write data.

It is small in size

SDD Pros:It is higher cost than hdd.



'iv'.MOTHERBOARD:It is used to connect all parts like cpu,ram,hard disk,cpu cooler,smps....etc.... with th help of cables and innter wiring.

Most motherboards are green in color some are different.

It is the body for coumputer.

'V'.SMPS:It is the adapter and power supplier,smps supplies dc power to all parts,it fixes at the top.smps has so many cables for each.

'Vi'.CPU COOLER:cpu cooler are used to reduce the heat in the cabinet and cpu.
cpu cooler are two types one is cooler fan,another is cooler.

Cooler fan is fixed at the top of the cpu and gives cool air to the cpu,it is very useful to the computer for cpu's better performence and in some computers the fans are fixed in smps and in some other places for cooling the cpu.
Cpu cooler fans are made of brushless motor because it make less noise.
Let us know about brushless motor on upcoming topics..........
Cpu cooler is works like an ac for better performance.


'Vii'.GRAPHICS PROCESSING UNIT(GPU):It is used to compose the screen graphics,it helps to cpu for composing screen.
Some GPU's are fixed in is fixed inside the cpu and some gpu's are connected externally,gpu's plays important role in graphics and screen composition.


Viii.Cables:cable or wires used for connecting motherboard and supies power to all parts by the help of wires,cables are same like human nerves.

'iX'.LAN card:lan means local area network,
Let us make a breif about it in the coming sections.......
