Study Notes
Data and Information
- Data refers to the facts and statistics collected together for reference or analysis, e.g., a list of names and addresses.
- Information is the result of organizing, analyzing, and interpreting data to extract meaningful patterns, relationships, or insights, e.g., a report on the most common addresses in a city.
System Development Life Cycle (SDLC)
- SDLC is a process used in information technology to design, develop, test, and deploy software systems or applications.
- It's important because it helps ensure that systems are developed on time, within budget, and meet user requirements.
Data Storage
- Basic units of data storage are:
- Bit (binary digit, 0 or 1)
- Byte (8 bits)
- Kilobyte (KB, 1024 bytes)
- Megabyte (MB, 1024 KB)
- Gigabyte (GB, 1024 MB)
Computer Networks
- A server is a central computer that provides services, resources, or data to other computers or devices in a network.
- It plays a crucial role in managing and controlling network access, storing data, and providing applications.
Computer Network Communication
- Uses of computer network communication:
- Resource sharing (e.g., printers, files)
- Communication (e.g., email, video conferencing)
- Collaboration (e.g., project management, group work)
- Benefits of computer network communication:
- Increased productivity
- Improved communication and collaboration
- Enhanced resource sharing and efficiency
Workgroup Computing and Groupware
- Workgroup computing refers to the use of computer networks to enable collaboration and communication among groups of people.
- Groupware is software that supports workgroup computing, e.g., collaborative writing tools, project management software.
Terminals
- A terminal is a device that allows users to access and interact with a remote computer or server in a network.
- Terminals can be computers, laptops, or specialized devices like thin clients.
Transmission Media
- Types of transmission media used to connect computers and devices in a network:
- Wired media: twisted pair cables, coaxial cables, fiber optic cables
- Wireless media: radio waves, microwaves, infrared signals
