Re take (best one ) Flashcards
Network Switch
Joins computers together on a LAN. Receives and sends packets.
Foreign Key
A field that links to a primary key in a second table.
Referential Integrity
When database relationships are consistent.
Multicore Processor
More than one processing unit in a single processor, which can process instructions at the same time.
IP Protocol
To route data
which type of data structure is a Linked List
Dynamic data structure.
OOP (Object-Oriented Programming)
Focuses on reusability and easy update of code.
Link Layer
Responsible for the transmission of data between two nodes over a physical connection
CU (Control Unit)
Sends out control signals to other parts of the CPU
PC (Program Counter)
Holds the address in memory of the next instruction
MAR (Memory Address Register)
Stores the address of the data that needs to be fetched from memory
MDR (Memory Data Register)
Stores the data that has been fetched from main memory
CIR (Current Instruction Register)
Stores the most recent instruction waiting to be decoded or executed
what happens in the Fetch stage(mention registers)
The PC copies the address of the next instruction into the MAR
Decode
The CU decodes the instruction
Execute
The CPU executes the instructions within the CIR
CISC (Complex Instruction Set Computer)
Supports more instructions, requiring more power and generating more heat
RISC (Reduced Instruction Set Computer)
Supports fewer instructions, requiring less power and generating less heat
GPU (Graphics Processing Unit)
An example of an array processor, used for parallel processing and tasks like breaking passwords
Parallel Processing
Simultaneous processing of data
SIMD (Single Instruction, Multiple Data)
Array processing where the same instruction is carried out on multiple data
MIMD (Multiple Instruction, Multiple Data)
Multicore processing where different instructions are carried out concurrently on different data
Flat File
A database storage where all the data is stored in one large table, with advantages in easy setup but redundant data
OCR (Optical Character Recognition)
Technology for converting printed or handwritten text into machine-readable data
