RAM: Random Access Memory - Responsible for storing temporary program data that is in use actively on the system.
BIOS: Basic Input/Output System - Responsible for setting/controlling the hardware of the system it is in. Helps hardware components talk to each other and to the operating system.
CPU: Central Processing Unit - Responsible for calculations and overall system interaction across the computer. The main "brain" of the machine.

I accept as true with you thoroughly. i'm stunned a appalled by utilising it. it particularly is our undesirable guidance equipment spoon feeding us and our young ones rubbish interior the situation of yankee history for the final 40 years or so. it particularly isn't any longer sufficient to easily examine the invoice of Rights and The shape devoid of first analyzing the Federalist Papers, the Anti-Federalist Papers, the Letters of Thomas Jefferson, The assertion of Independence, John Adams: techniques on government, Thomas Paine: undemanding experience, Frederick Bastiat: The regulation and greater. those archives are real history that designate each and each line of the form and invoice of Rights and the reasoning in the back of each observe. If the Sheeple do no longer desire to be knowledgeable, they are going to fall to tyranny by utilising those with a slick tongue and ulterior motives. you're basically loose till you resign you rights to those that will oppress you.

Ram:
Random access memory (usually known by its acronym, RAM) is a type of data storage used in computers. It takes the form of integrated circuits that allow the stored data to be accessed in any order — that is, at random and without the physical movement of the storage medium or a physical reading head. RAM is a volatile memory as the information or instructions stored in it will be lost if the power is switched off.
The word "random" refers to the fact that any piece of data can be returned in a constant time, regardless of its physical location and whether or not it is related to the previous piece of data.[1] This contrasts with storage mechanisms such as tapes, magnetic discs and optical discs, which rely on the physical movement of the recording medium or a reading head. In these devices, the movement takes longer than the data transfer, and the retrieval time varies depending on the physical location of the next item.
BIOS:
BIOS (pronounced [ˈbaɪoʊs]), in computing, stands for Basic Input/Output System.[1] [2]
The term is incorrectly known as Binary Input/Output System, Basic Integrated Operating System and occasionally Built In Operating System for example in Neal Stephenson's novel Snow Crash[1].
BIOS refers to the firmware code run by an IBM compatible PC when first powered on. The primary function of the BIOS is to prepare the machine so other software programs stored on various media (such as hard drives, floppies, and CDs) can load, execute, and assume control of the PC[3]. This process is known as booting up.
BIOS can also be said to be a coded program embedded on a chip that recognizes and controls various devices that make up the PC. The term BIOS is specific to personal computer vendors. Among other classes of computers, the generic terms boot monitor, boot loader or boot ROM are commonly used. Boot is short for bootstrapping.
The term first appeared in the CP/M operating system, describing the part of CP/M loaded during boot time that interfaced directly with the hardware (CP/M machines usually had a simple boot loader in ROM, and nothing else). Most versions of DOS have a file called "IBMBIO.COM" or "IO.SYS" that is
CPU:
Central Processing Unit (CPU), or sometimes simply processor, is the component in a digital computer capable of executing a program.(Knott 1974) It interprets computer program instructions and processes data. CPUs provide the fundamental digital computer trait of programmability, and are one of the necessary components found in computers of any era, along with primary storage and input/output facilities. A CPU that is manufactured as a single integrated circuit is usually known as a microprocessor. Beginning in the mid-1970s, microprocessors of ever-increasing complexity and power gradually supplanted other designs, and today the term "CPU" is usually applied to some type of microprocessor.
The phrase "central processing unit" is a description of a certain class of logic machines that can execute computer programs. This broad definition can easily be applied to many early computers that existed long before the term "CPU" ever came into widespread usage. However, the term itself and its initialism have been in use in the computer industry at least since the early 1960s (Weik 1961). The form, design and implementation of CPUs have changed dramatically since the earliest examples, but their fundamental operation has remained much the same.
Early CPUs were custom-designed as a part of a larger, usually one-of-a-kind, computer. However, this costly method of designing custom CPUs for a particular application has largely given way to the development of mass-produced processors that are suited for one or many purposes. This standardization trend generally began in the era of discrete transistor mainframes and minicomputers and has rapidly accelerated with the popularization of the integrated circuit (IC). The IC has allowed increasingly complex CPUs to be designed and manufactured in very small spaces (on the order of millimeters). Both the miniaturization and standardization of CPUs have increased the presence of these digital devices in modern life far beyond the limited application of dedicated computing machines. Modern microprocessors appear in everything from automobiles to cell phones to children's toys.

* Central processing unit (CPU) - The microprocessor "brain" of the computer system is called the central processing unit. Everything that a computer does is overseen by the CPU.
* Memory - This is very fast storage used to hold data. It has to be fast because it connects directly to the microprocessor. There are several specific types of memory in a computer:
o Random-access memory (RAM) - Used to temporarily store information that the computer is currently working with
o Read-only memory (ROM) - A permanent type of memory storage used by the computer for important data that does not change
o Basic input/output system (BIOS) - A type of ROM that is used by the computer to establish basic communication when the computer is first turned on
o Caching - The storing of frequently used data in extremely fast RAM that connects directly to the CPU
o Virtual memory - Space on a hard disk used to temporarily store data and swap it in and out of RAM as needed

BIOS
A typical computer session begins with turning on the power. Here's what happens in that process:
1. You press the "On" button on the computer and the monitor.
2. You see the BIOS software doing its thing, called the power-on self-test (POST). On many machines, the BIOS displays text describing such data as the amount of memory installed in your computer and the type of hard disk you have. During this boot sequence, the BIOS does a remarkable amount of work to get your computer ready to run.
* The BIOS determines whether the video card is operational. Most video cards have a miniature BIOS of their own that initializes the memory and graphics processor on the card. If they do not, there is usually video-driver information on another ROM on the motherboard that the BIOS can load.
* The BIOS checks to see if this is a cold boot or a reboot. It does this by checking the value at memory address 0000:0472. A value of 1234h indicates a reboot, in which case the BIOS skips the rest of POST. Any other value is considered a cold boot.
* If it is a cold boot, the BIOS verifies RAM by performing a read/write test of each memory address. It checks for a keyboard and a mouse. It looks for a PCI bus and, if it finds one, checks all the PCI cards. If the BIOS finds any errors during the POST, it notifies you with a series of beeps or a text message displayed on the screen. An error at this point is almost always a hardware problem.
* The BIOS displays some details about your system. This typically includes information about the following:
o Processor
o Floppy and hard drive
o Memory
o BIOS revision and date
o Display
* Any special drivers, such as the ones for SCSI adapters, are loaded from the adapter and the BIOS displays the information.
* The BIOS looks at the sequence of storage devices identified as boot devices in the CMOS Setup. "Boot" is short for "bootstrap," as in the old phrase "Lift yourself up by your bootstraps." Boot refers to the process of launching the operating system. The BIOS tries to initiate the boot sequence from the first device using the bootstrap loader.
3. The bootstrap loader loads the operating system into memory and allows it to begin operation. It does this by setting up the divisions of memory that hold the operating system, user information and applications. The bootstrap loader then establishes the data structures that are used to communicate within and between the sub-systems and applications of the computer. Finally, it turns control of the computer over to the operating system.
I hope it helps!
