RISC (Reduced Instruction set computer) AND CISC(Complex instruction set computer) ARCHITECTURE RISC(Reduced Instruction set computer): - Main idea behind is to make hardware simpler by using an instruction set composed of a few basic steps for loading, evaluating and storing operation just like load command will load data, store command will store data. Characteristic of RISC architecture:- 1. Simpler instructions, hence simple instruction decoding. 2. Instruction come under size of one word. 3. Instruction take single clock cycle to get executed. 4. More number of general purpose register. 5. Simple addressing mode. 6. Less data type. 7. Pipelining can be achieved. CISC(Complex instruction set computer): - Main idea is to make hardware complex as a single instruction will do all loading evaluating and storing operation just like a multiplication command will do stuff like loading data, evaluating and storing it. Characteristic of CISC architecture: -
what is internetworking and internet? we have heard about the internet everyone knows about internet nowadays internet come from internet working this a collection of packet switching and broadcast networks That are connected together so this picture is from a text so it's kind of older text so is they have the US backbone and the European backbone they're supposed to be like Thailand somewhere there and also there is leased line to Asia this Trans-Atlantic line something Like that so then they’re connected to the regional network and the regional network also connected to the LAN inside of also connected to the LAN. so it's becoming like smaller and smaller so that time we still have the Token bus and Token Ring in use a lot and then we have also the Ethernet LAN so you can see that there is a national network from the backbone go to national network and then go to the smaller network like LAN . so basically internetworking means that you connect different netwo
