A motherboard (alternatively known as the mainboard, main circuit board, system board, baseboard, planar board or logic board, or colloquially, a mobo) is the main printed circuit board (PCB) found in general purpose computers and other expandable systems. It holds, and allows communication between, many of the crucial electronic components of a system, such as the central processing unit (CPU) and memory, and provides connectors for other peripherals. Unlike a backplane, a motherboard usually contains significant sub-systems such as the central processor, the chipset's input/output and memory controllers, interface connectors, and other components integrated for general purpose use and applications.
Motherboard specifically refers to a PCB with expansion capability and, as the name suggests, this board is often referred to as the "mother" of all components attached to it, which often include peripherals, interface cards, and daughtercards: sound cards, video cards, network cards, hard drives, or other forms of persistent storage; TV tuner cards, cards providing extra USB or FireWire slots and a variety of other custom components.
A motherboard provides the electrical connections by which the other components of the system communicate. Unlike a backplane, it also contains the central processing unit and hosts other subsystems and devices.
A typical desktop computer has its microprocessor, main memory, and other essential components connected to the motherboard. Other components such as external storage, controllers for video display and sound, and peripheral devices may be attached to the motherboard as plug-in cards or via cables; in modern microcomputers it is increasingly common to integrate some of these peripherals into the motherboard itself.
An important component of a motherboard is the microprocessor's supporting chipset, which provides the supporting interfaces between the CPU and the various buses and external components. This chipset determines, to an extent, the features and capabilities of the motherboard.
Motherboards contain some non-volatile memory to initialize the system and load some startup software, usually an operating system, from some external peripheral device. Microcomputers such as the Apple II and IBM PC used ROM chips mounted in sockets on the motherboard. At power-up, the central processor would load its program counter with the address of the boot ROM and start executing instructions from the ROM. These instructions initialized and tested the system hardware displayed system information on the screen, performed RAM checks, and then loaded an initial program from a peripheral device. If none was available, then the computer would perform tasks from other memory stores or display an error message, depending on the model and design of the computer and the ROM version. For example, both the Apple II and the original IBM PC had Microsoft Cassette BASIC in ROM and would start that if no program could be loaded from disk.
A CPU socket (central processing unit) or slot is an electrical component that attaches to a Printed Circuit Board (PCB) and is designed to house a CPU (also called a microprocessor). It is a special type of integrated circuit socket designed for very high pin counts. A CPU socket provides many functions, including a physical structure to support the CPU, support for a heat sink, facilitating replacement (as well as reducing cost), and most importantly, forming an electrical interface both with the CPU and the PCB. CPU sockets on the motherboard can most often be found in most desktop and server computers (laptops typically use surface mount CPUs), particularly those based on the Intel x86 architecture. A CPU socket type and motherboard chipset must support the CPU series and speed.
Ask me about:
Intel's top CPUs cost more than their AMD counterparts, especially once you add in a decent cooler, but they're often a bit faster in games. AMD meanwhile is able to trounce Intel when it comes to multithreaded applications
A clock speed of 3.5 GHz to 4.0 GHz is generally considered a good clock speed for gaming but it's more important to have good single-thread performance. This means that your CPU does a good job of understanding and completing single tasks. This is not to be confused with having a single-core processor
If you're sitting idle, it can be as little as 3%. If you're gaming you can be anywhere between 20 and 80% depending on the game, even spiking up to near 100% at times is sill deemed normal. Now you shouldn't be standing stagnant at +95% for long periods of time, unless for a specific reason
The main function of hard disk is to store data for long term and data can be computer's operating systems, applications, documents, personal files and so on. Now the main thing that need to notice that how much amount of data storage capacity hard drive have and that measured in gigabytes or terabytes.
Seagate
The most well-known hard drive brands include Seagate, Western Digital, Toshiba and Hitachi, while others such as Samsung, SanDisk and G-Tech also offer sleek and powerful external storage or solid state drives
Seagate just announced its new 12TB BarraCuda Pro 3.5-inch hard drive, which becomes the world's fastest and highest-capacity desktop hard drive
First, consider the total capacity of memory you're looking for. We recommend a minimum of 16GB for most PCs (it's what we use in our high-end PC build) but it isn't too costly to upgrade to 32GB these days which provide a hefty buffer if you're inclined to multitasking.
In general, we recommend at least 4GB of RAM and think that most users will do well with 8GB. Choose 16GB or more if you're a power user, if you run today's most demanding games and applications, or if you simply want to make sure you're covered for any future needs.
