Desktop or Laptop?

How about we go shopping for a new computer system for you? First we'll have to figure out if a desktop or a laptop is going to be best for you.

Laptops are for the user who prefers portability. This unit is common for someone like - a college student, consumers who travel frequently and business people who find themselves working in places other than their office.

The desktop, or tower, is intended for a user who doesn't need a computer that is portable. They are larger in design and often have more features and computing power.  

Now you know what is the differences between the two are, which system seems like it would be best for your situation?

1.)Motherboard:

Now the First Thing in Desktop is Motherboard.All things like Processor,Ram,Storage Devices(Hard Disk),Graphic Card,DVD-ROM,PCI Slot And other External Devices are Connected to Motherboard.

Best Motherboard Brand Are:- Gigabyte,Msi,Asus,Intel

2.) Processor (CPU):

The central processing unit, or the brains of the computer, sits on the motherboard and does actually have its own cooling fan. The processors now are so fast they need to be cooled down. All the instructions you give the computer - like a click of a mouse - go through the CPU, which processes in billions of cycles per second. Commonly installed processors have Dual-cores or quad-cores. There are six-core and eight-core available, and they are more advanced technology but higher the cost.

The speed of a computer depends largely on the speed of the processor. The processor’s speed, in turn, is affected by various factors, such as the so-called clock frequency (usually expressed as gigahertz, GHz), the amount of cores and of the so-called cache memory inside the processor.

CPU Brand : INTEL,AMD. 

3.)Random access memory (RAM):

Next to the CPU sits the cache, or the temporary memory where things you are working on sit for quick interpretation by the CPU. The RAM chip is also near this location. Random-access memory is volatile, or temporary, memory. Whenever you turn on a program, its instructions are stored in RAM while the machine is on. Once you shut the machine down, both the cache and the RAM are completely cleared out.The RAM (Random Access Memory) is a memory storage that functions during computer use and is especially utilised by the processor. In modern computers, the amount of RAM is around 4 – 16 GB depending on the type and purpose of the computer (Normal Use 4-8GB, Gaming 8-16GB).
Best Brand: Corsair,Kingston 

 4.) Hard Drive (HDD):

The hard drive is the permanent memory of the computer where saved files remain even when the computer is turned off. This is why the hard drive is used for saving files.
The hard disk is used for the storage of the computer’s operating system and all important files. It is therefore packed in a fixed protective housing.
Hard drive storage commonly begins at one terabyte(TB) now
Best Brand: WD(Western Digital).

5.) DVD ROM

Most computers these days come with a  Blu-ray drive or a DVD (Digital Versatile Disk) drive with writing capabilities, with which you can burn such things as backup copies of important files to DVDs.

6.) Graphic Card (Video Card): {Optional}

A video card (also called a display card, graphics card, display adapter or graphics adapter) is an expansion card which generates a feed of output images to a display (such as a computer monitor). Frequently, these are advertised as discrete or dedicated graphics cards, emphasizing the distinction between these and integrated graphics.The images you see on your monitor are made of tiny dots called pixels. At most common resolution settings, a screen displays over a million pixels, and the computer has to decide what to do with every one in order to create an image. To do this, it needs a translator -- something to take binary data from the CPU and turn it into a picture you can see. Unless a computer has graphics capability built into the motherboard, that translation takes place on the graphics card.
Brand: Nvidia,AMD

7.) Monitor:

A computer monitor or a computer display is an electronic visual display for computers. A monitor usually comprises the display device, circuitry, casing, and power supply. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) or a flat panel LED display, while older monitors used a cathode ray tubes (CRT). It can be connected to the computer via VGA, DVI, HDMI, DisplayPort, Thunderbolt, LVDS (Low-voltage differential signaling) or other proprietary connectors and signals.
BEST BRAND:- Samsung,Dell,HP(20inch+)

 8.) POWER SUPPLY UNIT (SMPS,PSU):

A power supply unit (or PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer. Modern personal computers universally use switched-mode power supplies. Some power supplies have a manual switch for selecting input voltage, while others automatically adapt to the mains voltage.
Most modern desktop personal computer power supplies conform to the ATX specification, which includes form factor and voltage tolerances. While an ATX power supply is connected to the mains supply, it always provides a 5 Volt standby (5VSB) voltage so that the standby functions on the computer and certain peripherals are powered. ATX power supplies are turned on and off by a signal from the motherboard. They also provide a signal to the motherboard to indicate when the DC voltages are in spec, so that the computer is able to safely power up and boot. The most recent ATX PSU standard is version 2.31 of mid-2008.
