Study Notes
Computer Architecture and Organization
- A JUMP instruction alters the normal course of a program by causing it to jump to another instruction.
- A STORE instruction causes data in the accumulator to be moved to the memory or a peripheral register.
Registers and Counters
- The program counter is a specific register that always points to the address of the next instruction to be executed.
- The instruction register holds the current instruction during its execution.
Memory and Storage
- Cache memory is a high-speed memory used to store a small amount of data temporarily for quick retrieval.
- Firmware refers to programs stored in ROMs and EPROMs.
- A nibble is composed of 4 bits.
- BCD code has 4 bits per number.
Input/Output and Networking
- A server is a computer or software on the network that supplies the network with data and storage.
- The control bus directs memory and I/O devices transfers.
- A non-impact printer that forms images with little dots and produces high quality images is an Ink jet printer.
Programming Languages and Codes
- HTML (Hypertext Mark-up Language) is the language used in making an internet web page.
- BCD (Binary Coded Decimal) takes a complete decimal number and presents it in binary.
- DCTL stands for Direct Coupled Transistor Logic.
- DTML stands for Diode Transistor Micro Logic.
Data Representation and Storage
- A group of records are stored in a file.
- A relational database contains records in an organized, structured format.
- A database with records in an organized, structured format is a relational database.
Computer Hardware and Components
- The most common type of digital IC package is DIP (Dual In-Line Package).
- The CD drive is connected to the motherboard via the IDE slot.
- A buffer is a two-way parallel path connecting processors and memory containing addresses.
Other Key Concepts
- A benchmark is a program executed on several different computers to compare their speed and performance.
- Access time refers to the time it takes for a disk to find data being sought.
- Logical complementation is a basic operation in Boolean Algebra.
- The command line in basic programming is always started by a keyword.
