history
Emergence of personal computers: In the 1980s,
1970, the first computers were launched on the market
such as the Altair 8800 and the Apple II.
Mobile Computing and Cloud Era: In the Past
decades, we have witnessed the proliferation of devices
mobile phones, such as smartphones and tablets, which have allowed the
access to information and services at any time and
place.
The First Computers: During World War II
Worldwide, the first computers were developed electronic technologies, such as the Colossus in the United Kingdom and the
ENIAC in the United States.
Background: The first attempts to process
information dates back to antiquity, with the use of devices such as the abacus and astrolabe.
Globalization of information
Challenges and opportunities: While the globalization of the
information has provided numerous opportunities, has also
posed challenges.
Advancement of ICT: The rapid development and advancement of ICT,
such as the Internet, communication networks,
mobile and cloud storage, have enabled rapid transfer and access to information anywhere in the
world.
Access to Information: The Globalization of Information Has
democratized access to it. Now, people
They can access a wide variety of information, such as news, research, educational and cultural resources, from
any location.
Internet Security
Secure Wi-Fi networks: Use secure Wi-Fi networks and avoid
connect to unprotected public networks while driving
sensitive information.
Software updates: Keep your operating system,
Browsers and apps updated with the latest
security patches and updates.
Two-factor authentication (2FA): Enables
Two-factor authentication whenever possible.
Strong passwords: Use strong, unique passwords
for all your online accounts.
Safe browsing: Use secure HTTPS connections when
Visit websites to protect privacy and integrity
of the data. Also, avoid clicking on links suspicious or download attachments from non-suspicious sources
Reliable.
Antivirus and security software: Install software
Reliable antivirus and a firewall on your device to
detect and block malware and other threats.
Operating systems and social media
Types of Functions
Server operating systems: They are used in servers
to manage resources and provide services to others
devices on a network.
Desktop operating systems: They are designed for use in
personal computers and provide a graphical interface of
user (GUI) that facilitates interaction with the system.
Mobile operating systems: They are designed for mobile devices.
such as smartphones and tablets.
Functions
Process management: The operating system manages execution
of system processes, allocating CPU time,
planning the execution and coordinating the communication between the
Processes.
is a fundamental software that acts as an intermediary between
the hardware and users of a computer system.
Resource Management: The operating system manages and
allocates system resources, such as CPU, memory,
input and output devices, and storage, for
ensure efficient and equitable use.
Memory management: The operating system manages memory
of the system, allocating memory space to programs, and
data that is being used, and freeing up memory when no longer
it is necessary.
The Central Processing Unit
CPU functions: The CPU has three functions
search for instructions decode them, and
Run. Receive instructions and data from memory and processes them through arithmetic operations,
logical and control.
CPU Components
CPU speed: CPU speed is measured in hertz
(Hz) anddetermines the number of instructions that the CPU can
Run in a second
Control Unit (UC): Controls and coordinates the operations of
the CPU,interprets the instructions, and directs the flow of data
within the system.
Arithmetic-Logic Unit (ALU): Performs arithmetic operations
and logic, such as addition, subtraction, multiplication, comparison, and
Boolean operations.
Registers: These are small high-quality storage areas
speedused to store data and results
during CPU operations.
