6. A motherboard provides connectivity between the hardware
components of a computer, like the processor (CPU), memory (RAM),
hard drive, and video card. There are multiple types of motherboards,
designed to fit different types and sizes of computers.
Each type of motherboard is designed to work with specific types of
processors and memory, so they don't work with every processor and
type of memory. However, hard drives are mostly universal and work
with the majority of motherboards, regardless of the type or brand.

8. A processor is an integrated electronic circuit that performs the
calculations that run a computer. A processor performs
arithmetical, logical, input/output (I/O) and other basic
instructions that are passed from an operating system (OS). Most
other processes are dependent on the operations of a processor.
The terms processor, central processing unit (CPU) and
microprocessor are commonly linked as synonyms. Most people
use the word “processor” interchangeably with the term “CPU”
nowadays, it is technically not correct since the CPU is just one of
the processors inside a personal computer (PC).
The Graphics Processing Unit (GPU) is another processor, and
even some hard drives are technically capable of performing some
processing.

10. RAM (Random Access Memory) is the hardware in a computing device
where the operating system (OS), application programs and data in
current use are kept so they can be quickly reached by the device's
processor. RAM is the main memory in a computer. It is much faster to
read from and write to than other kinds of storage, such as a hard disk
drive (HDD), solid-state drive (SSD) or optical drive.
Random Access Memory is volatile. That means data is retained in RAM as
long as the computer is on, but it is lost when the computer is turned off.
When the computer is rebooted, the OS and other files are reloaded into
RAM, usually from an HDD or SSD.

12. The manufacturer of ROM fills the programs into the ROM at
the time of manufacturing the ROM. After this, the content of
the ROM can't be altered, which means you can't reprogram,
rewrite, or erase its content later. However, there are some
types of ROM where you can modify the data.
The information is added to a RAM in the form of bits by a
process known as programming the ROM as bits are stored in
the hardware configuration of the device. So, ROM is a
Programmable Logic Device (PLD).

14. The difference between RAM and ROM

15. The difference between RAM and ROM
random memory (RAM):
This memory saves the data and information that the user
performs various operations on, as it receives data and
information from the various input units, as well as the results
from the processing units after the required procedure is
performed on them, and RAM stores all this data temporarily, and
this memory is affected by the disconnection of the electric
current from the Computer or computer shutdown, all the
information you have stored disappears, and this memory is
faster than ROM.
Read Only Memory (ROM):
This memory stores the drivers and basic programs that run the
computer, and this memory cannot be modified or erased
because it is stored from the main manufacturer, and the
computer cannot work without this memory, and it is not affected
by the power outage of the device, Its data can even be restored
when the device is turned on again.

17. GPUs were originally designed to accelerate the rendering of 3D
graphics. Over time, they became more flexible and
programmable, enhancing their capabilities. This allowed graphics
programmers to create more interesting visual effects and realistic
scenes with advanced lighting and shadowing techniques. Other
developers also began to tap the power of GPUs to dramatically
accelerate additional workloads in high performance computing
(HPC), deep learning, and more.

24. WHAT IS THE INTERNET ??

25. It is a global communication system that allows information to be exchanged
between smaller networks through which computers are connected around the
world. It operates according to specific systems, known as the Unified Protocol,
which is an Internet protocol. The word “Internet” refers to the set of information
circulating over the network, as well as to the infrastructure that transmits that
information across continents.
The Internet connects millions of private and public networks in academic,
governmental and business institutions and varies in scope between local and
global and relates to different technologies, such as copper wires, optical fibers
and wireless connections. The other is decentralized and none of them depends
for its operation on the others.
The Internet today carries a great deal of data and services, perhaps the most
common of them today are hypertext pages published on the Web, and it also
carries other services and applications such as mail and instant messaging
services, file transfer protocols, voice communication and others.
