This document provides an overview of the main internal components of a computer, including the CPU, memory types, storage drives, adapter cards, expansion slots, input and output devices. It discusses the CPU's role in controlling the computer and different CPU types. It also explains different memory types like SRAM, EEPROM, and flash memory. Storage drives, adapter cards, and expansion slots are covered to describe how components connect inside the computer. Input devices like keyboards and mice and output devices like monitors and printers are highlighted.

2. Hey.
This is my presentation for you guys who are new to
using computers. Am I right.
I will tell you about those small components in a
computer. These are called ‘Internal Components’.
I will not tell you about each one in detail but I will
cut it down to the main parts of information.

3. The CPU stands for Central Processing Unit. It
controls everything on the computer.
RISC (Reduced Instruction Set Computer) and CISC
(Complex Instruction Set Computer) are the two types
of CPU.
Overclocking is used to make a processor work at a
faster speed than its original specification.
MMX is a set of multimedia instructions built into Intel
processors.
CPU size is measured in Bytes . CPU speed is measured
in GHz. Cool or what.

6. SRAM is known as Cache
It is used to store the most used data.
It provides fast access to data.
The re are three main types of cache memory. L1, L2
and L3.

7. Dynamic Temporary Storage is the core function of
computers in memory.
There are many different types of memory like:
-SDRAM
-GB PATA
-SDLT

8. EEPROM stands for Electrically Erasable Programmable
Read-Only Memory).
It is a type of memory that can delete the stored
information even when not powered on.
The data must be saved before the computer is
powered off.

9. Flash Memory is memory that can delete stored data
even when the computer is not powered on.
It was developed by EEPROM
USB Memory Sticks and Memory Cards are types of
Flash Memory.

10. Adapter Cards give a lots of capability to the
computer by making it bigger and customizing it.
There are lots of different kinds of Adapter Cards.
Network Interface Cards (NIC), Wireless NIC, Sound
Adapter, Video Adapter, Capture Card, TV Tuner,
Modem Adapter, SCSI Adapter and RAID Adapter.

11. Expansion Slots lets you plug in Adapter Cards on the
Motherboard.
The type of Adapter Card must match with the
expansion slot.
There are lots of different kinds of Expansion Slots .
PCI, AGP, PCle, ISA, EISA and MCA.

12. Storage Drives read or write information to optical
storage media.
SATA refers to the serial versions of the ATA drive
controller.
PATA refers to the parallel version of the ATA drive
controller interface.
SCSI can connect both internal and external drives.
Partitioning and Formatting is when you set up a new,
empty hard disk so that you can put it into an
Operating System.

13. An Input Device is used to put data into a computer by
plugging it into the computer.
Input Devices are devices like:
 Mouse
 Keyboard
 Camera
 Biometric Authentication Device
 Touch Screen
 Scanner

14. An Output Device is used to take information from a
computer by using special equipment.
Output Devices are devices like:
 Monitors
 Projectors
 Printers
 Scanners
 Fax Machines
 Speakers
 Headphones
