COMPUTER NETWORKS
HOW IT WORKS
Interconnection: Device are linked together using various communication links, which can me wired or wireless.
Protocols: The devices follow a set of rules called communications protocols which are like a common language that allows them to exchange inmfomations correctly.
Data exchange: Networks allow for the rapid and efficient sending and receiving of informations between devices
Resource sharing: The main purpose of a network is to enable the efficient sharing of resources.
EXAMPLES
Accessing websites and video
Sending emails and messages
Sharing files
Using a shared printer from multiple device
Collaborating on documents in real time
KEY COMPONENTS
Devices: Networks consist of various devices, known as nodes, including computers, servers, printers, routers, and switches. End devices are the source or destination of data, while intermediary devices forward it.
Transmission media: Devices are connected via physical cables (like fiber optics) or wireless methods (like radio waves).
Protocols: A set of rules called communication protocols, such as TCP/IP, govern how devices exchange data over the network. Resource and data sharing: The primary purpose is to share resources like printers and applications, and to allow for easy data exchange.Communication: Networks facilitate communication through tools like email, instant messaging, and video conferencing.
computer system
definition
A computer system is a combination of hardware, software, and users (brainware) that work together to process data and perform tasks. Its core components include the central processing unit (CPU), memory, input/output devices, and storage, all of which interact with system and application software to function.
Key components
Hardware:
The physical parts of the system that can be seen and touched.
Processing Unit: The CPU, which performs calculations and executes instructions.
Memory: Both primary memory (RAM), which is temporary storage for active data and programs, and secondary memory (like a hard drive), which is for permanent storage.
Input Devices: Devices that send data to the system, such as a keyboard or mouse.
Output Devices: Devices that show the results of processing, like a monitor or printer.
Storage: Devices for long-term storage of data and instructions.
Software:
The programs and instructions that tell the hardware what to do.
System Software: Includes the operating system, which manages the system's resources and allows other programs to run.
Application Software: Programs that perform specific tasks for the user, such as word processors or web browsers.
how it works
Input: Data is sent to the system through input devices.
2.Processing: The CPU processes the data, using the memory to temporarily store it.
3.Storage: The results are stored permanently in secondary storage for future use.
4.Output: The results are displayed or sent to an output device.
