10.2 IPEKA Puri Informatics Laurencia
Computer Network
: a group of computers connected to each other to exchange data and information.
Types Based on Range
MAN ( Metropolitan Area Network) city scale, universities.
WAN (Wide Area Network) large scale, inter-country.
PAN (Personal Area Network) 10 meters range, bluetooth.
CAN (Campus Area Network) 1-5 km.
SAN (Storage Area Network).
LAN (Local Area Network) small scale, schools, homes, offices.
Network Types
Cable: wired connections
Wireless: wireless connection
Computer Network Components
Hardware: cables, switches router (physical component)
Software: network, operating systems (intangible sets of information)
User: a person who accesses the network.
Benefits of Computer Networks
Sharing data and information
Sharing hardware (printers, scanners)
Faster communication
Time and cost efficiency
Internet
: the largest computer network
Benefits of the Internet
Source of information and knowledge
Communication media
Supports online learning
Internet Services
Web: site page based information
Email: electronic mail
Cloud storage: online storage
Social media: online interaction between users
Computer System
: a combination of hardware and software that works together to process data and perform tasks.
Hardware
: the physical components of a computer system.
Key Components of Hardware
CPU: the brain of a computer processing data.
Memory: temporary storage for active processes and data.
Input & Output
:Input devices: essential tools for user interaction with computers. (sends data)
Output devices: visual and audio results from computer operations. (receives and acts on the data)
Types of computer systems
Desktop computers: designed for stationary use, featuring powerful hardware components. They offer high performances for tasks such as gaming, graphic design, and productivity applications.
Laptop computers: provides portability, combining essential components into a compact design.
Server systems: servers are specialized computers that manage resources and provide services to other computers over a network. They handle multiple requests simultaneously, ensuring data accessibility and reliability.
Software
: intangible sets of instructions
ICT
Google Workplace
Integration
You can easily insert tables and charts from Sheets to Docs.
Presenting data visually.
Importing text from Google Docs into Slides.
Transforming slides into engaging videos.
Benefits
Time saving features.
Improved teamwork which led to better communication on projects.
Maintaining data consistency minimizes errors and ensures information is always up to date.
Computational Thinking
: a problem-solving approach inspired by computer science that helps breakdown complex issues into manageable parts, emphasizes logical, creative, and systematic thinking.
Decomposition
: breaking down complex problems into smaller, manageable parts which makes it easier to address each component.
Pattern Recognition
: identifying patterns allows us to solve problems more efficiently by applying solutions from other similar situations.
Abstraction
: ignoring irrelevant details and focusing on the important features.
Algorithm
: a set of clear instructions to solve a problem.
Sorting
Bubble sort
: repeatedly swap elements if they are in the wrong order.
Insertion sort
: build the sorted list one time item at a time by inserting elements into the correct position.
Merge sort
: divide each list into halves, sort each half, then merge them.
Selection sort
: finds the smallest item and places it at the beginning.
Searching
: the process of locating specific data within a collection, which helps us retrieve and identify information efficiently in various contexts, like technology and daily tasks.
Linear search
: Linear search checks each element sequentially. It works on unsorted data efficiently.
Binary search
: Binary search divides and conquers the dataset. It requires sorted data for optimal performance. This approach is efficient for large datasets.
