1. WHAT IS
PROCESSER?
Processor which is also called the central processing unit
(CPU)
interprets and carries out the basic instructions that operate
a computer..
2. ⢠The operating system views each processor
as a separate processor.
multi-core processor
ɡ it is a processor with a single chip
with two or more separate processor
cores.
3. THE COMMON MULTI-CORE PROCESSOR ARE DUAL-
CORE AND QUAD-CORE.
⢠A dual-core processor is a chip that contains TWO separate
processor cores.
⢠A quad-core processor is a chip with FOUR separate processor
cores.
4. When a user starts a program, for example its instruction transfer
from a storage device to memory. Data needed by programs enters
memory from either an input device or a storage device.The control
unit interprets in memory and ALU performs calculation the data in
memory. Resulting information is stored in memory for future access...
INPUT DEVICES
â data
MEMORY
â information
OUT DEVICES
5. ⢠Processors contain a control unit and an
arithematic logic unit (ALU).
⢠These two components work together to
perform processing operations.
6. THE CONTROL UNIT
⢠Is the component of the processor that directs
and coordinates most of the operations in the
computer.
⢠It interprets each instruction issued by a
program and then initiates the appropriate
action to carry out instruction.
7. ⢠There are a few types of internal components that control
units direct such as:
a) arithematic logic unit
b) registers
c) buses
8. Parallel processing
⢠is a method that uses multiple processors simultaneously to
execute a single program or task
⢠it divides a single problem into portion so that multiple
processor work on their assigned portion of the problem at
the same time.
10. MEMORY
⢠It consists of electronic components that store
instructions waiting to be executed by the
processor.
⢠The role of memory is to store both data and
programs which is known as the stored
programs concept.
11. ⢠Memory stores three basic categories items:
a) the operating system and other
system software that controls or
maintain the computer and its
devices.
b) application programs that carry out a
specific task such as word processing
c) the data being proccesed by the application
programs and resulting information.
12. Bytes and Addressable
Memory
⢠A byte (character) is the basic storage unit in
memory.
⢠The data are transferred to memory from
storage devices where the instructions and data
exsist as bytes.
⢠Each byte resides temporarily in a location in
memory that has a address.
13. Types Of Memory
⢠There are two types of memory:
a) volatile
b) non-volatile
14. ⢠When the computer's power is turned off
volatile memory loses its contents.
⢠Non-volatile, by contrast, does not loses its
contents when the power is removed from the
computer.
⢠Thus, volatile memory is temporary and non-
volatile memory is permenant.
⢠RAM is the most common type of volatile
memory.
15. ⢠Examples of non-volatile include ROM, flash
memory, and CMOS.
⢠These are the few examples of memory:
