Study Notes
Cybercrime and Digital Footprints
- Cybercrime involves illegal activities online, examples include phishing and identity theft.
- Phishing is a fraudulent attempt that deceives users into giving up sensitive information.
- A digital footprint is a record of online activity.
- Avoid responding to emails asking for personal info, and report suspicious emails.
Python Programming Concepts
- There are 8 possible combinations for 3 binary inputs.
- 10 % 2 equals 0 in Python.
- 4 possible combinations for 2 binary inputs.
- Logical OR is represented by || and AND by && in Python.
- An AND operation is True only if both inputs are True.
- An OR operation is False only if both inputs are False.
- Truth tables show all possible input combinations and outputs of logical operations
- Compilers translate entire code at once, interpreters translate line by line.
- Python variable names start with a letter or underscore, and can contain letters, numbers, and underscores.
- Simple Python programs involve taking inputs and using operators (+, -).
- A translator converts high-level code to machine code for execution.
Networking Concepts
- Data transmission modes include simplex, half-duplex, and full-duplex.
- Network types include LAN, PAN, MAN, and WAN.
- bps stands for bits per second.
- A switch connects multiple computers in a LAN.
- A router connects multiple networks.
- Latency is the time to send the first byte of data.
- Bandwidth is calculated as (bits transmitted / time in seconds).
- MAC addresses are stored on a device's NIC.
- A protocol is a set of rules for data communication.
- NIC stands for Network Interface Card.
- A switch sends data only to intended devices in a LAN
- There are 8 bits in a byte and 1024 bytes in a kilobyte.
- A hub broadcasts data to all devices - a switch sends only to the intended device.
- Bandwidth may be different from throughput; a router directs data packets between networks.
