10Base-2 is a type of Ethernet used to create
Local Area Network. These are known as ThinNet as it uses 50ohm coaxial
cable which is more flexible and thinner than the cable that is used by 10Base-5
standard. The maximum length of the cable supported by 10Base-2 is 185
meters and have the maximum capacity of 10Mbit/s. The cables are terminated
using BNC connectors and Network Interface Card in a computer require a T-connector
to connect using BNC connectors.
The Simple-As-Possible (SAP)-1 computer is a very basic model of a microprocessor explained by Albert Paul Malvino. The SAP-1 design contains the basic necessities for a functional Microprocessor. Its primary purpose is to develop a basic understanding of how a microprocessor works, interacts with memory and other parts of the system like input and output. The instruction set is very limited and is simple. The features in SAP-1 computer are: W bus – A single 8 bit bus for address and data transfer. 16 Bytes memory (RAM) Registers are accumulator and B-register each of 8 bits. Program counter – initializes from 0000 to 1111 during program execution. Memory Address Register (MAR) to store memory addresses. Adder/ Subtracter for addition and subtraction instructions. A Control Unit A Simple Output. 6 machine state reserved for each instruction The instruction format of SAP-1 Computer is (XXXX) (XXXX) A Simple animation ...
