The OS can load device drivers on startup to probe (examine) memory locations for answers from hardware that the System ROM can't know about (never programmed in or too new for it to understand it).
Device drivers are how computers can know about devices that are not in the system ROM. The drivers would scan the addresses where the devices are found and load if the devices are present. Drivers are a way to artificially extend the functionality of the ROM BIOS (or EFI). The OS loads the system drivers.
A metaphorical example might be a literal city bus driver. The driver starts the bus, it runs, and he adds people, but the bus itself doesn't know anything about people, just about running. The driver makes the difference. In this analogy, the Bus is the computer with System ROM, the driver is the operating system and/or device drivers, and the people are the devices being connected or disconnected.

Why are peripheral devices important to the computer system?
Peripheral devices are devices used with a computer. Most think of peripherals as non-essential devices like printers, mice, joysticks, speakers, etc. The exact function depends on the exact peripheral.
When was the computer algebra system MATHLAB created?
Algebra systems were created in the 1960's, but more specifically MATHLAB was created in 1964. More easily known as computer algebra systems (CAS). A gentleman called Carl Engelman was the creator of this system and has become quite well known for this system this is popular know for taking mathematical equations and transforming them into a symbolic form.

GIVE FIVE examples of a peripheral devices of a computer?
Sure thing, honey. Here's a little lesson for you: a mouse, a keyboard, a printer, a scanner, and a webcam are all examples of peripheral devices for a computer. Now you know, darling.
What is the purpose of output devices?
Hy whoever want to know its so simpleOutput devices are used to show result or any information you want to seefor e.g a monitor, a printer,a fax machine etcdonot mistake a usb,hard disc these are storage devices

Which program controls the hardware and software in a computer?
The BIOS manages the data between the operating system and all input and output devices attached to the system. The programs that manages operation and data transfer between computer programs and the attached devices are called device drivers, device handlers. device processors, io handlers, and other names depending on the computer and operating system. These programs are usually included with the operating system or added to the operating system to support devices not originally known to the operating system. On a PC (the common Personal Computer) these programs are included in the flashable read only memory called the system BIOS (Basic Input Output System). Besides basic system startup testing and functionality, it also provided a device driver interface for software to access standard known devices on the machine without the programs having to know the specifics of hardware programming. Some operating systems and standalone software supply their own device drivers (ignoring BIOS provided versions) either to support devices not supported by the BIOS or to supply more efficient or more capable implementations of device drivers.

What is a processing devices main purpose?
processing devices are electronic components that performs various functions in a computer or other electronic system. some common function of processing devices includes Data processing : These devices take in data and perform operations on it such as calculation, addition, or logic operations. memory management : These devices store and retrive data for use by the processing devices. communication: these devices allow different part of the system to communicate with each other, such as through a bus or network. 4.input output i/p, o/p management: these devices control the flow of data into and out of the system, such as through keyboard, mouse , or other peripherals. power management : these devices regulate the power to the system such as by controlling the voltage and current. error correction : these devices detect and correct errors in data transmission and storage. security : these devices provides security feature such as encryptions, firewall, and access controls. 8.multitasking : these devices allow the system to perform multiple tasks at the same time.

What number system does a computer use that is on?
Computers are not smart They only know 0 and 1 or binary states or true or false. this language is known as machine language
Why do you need a device driver on your computer?
A device driver is a set of rules and instructions that your operating system uses to know how to communicate with a specific piece of hardware like a scanner, printer and even the video and sound cards on your computer. As you get different types of printers, video cards, sound cards, etc your operating system needs this driver information to know how to send instructions to these devices in order for it to use them correctly.
Why is it important to know how many system words will fit in a primary storage device on a computer?
It is important to know how many system words will fit in a primary storage device on a computer so you know how big of a storage unit you have. The more system words that will fit in a primary storage device, the more memory you have on your computer.

it consists of 5 types i know three integrated customized and general
What is CIH also know as?
CIH is also known as the "Chernobyl" virus. It is a destructive computer virus that infects executable files and overwrites critical system data, leading to system crashes and rendering the computer inoperable. It was named after the 1986 Chernobyl nuclear accident.
