Topology and its Types in Networking

Physical Topology : It refers to the way in which a network is laid out physically or physical representation of the computer network is known as topology in networking. 1.Mesh Topology:- Every device has a dedicated point-to-point link to every other device. In mesh topology, we need (n*(n -1)) /2 duplex-mode links. Advantages : Dedicated… Continue reading Topology and its Types in Networking

What are the Components of Data Communication?

a. Components Of Data Communication. Message : The message is the information (data) to be communicated. e.g text, numbers, pictures, audio, and video. Sender : The sender is the device that sends the data message. e.g computer, workstation, telephone handset, video camera, and so on. Receiver : The receiver is the device that receives the… Continue reading What are the Components of Data Communication?

Types Of ARM Instruction

ARM Instruction Types of ARM instruction, The ARM  processor uses 3 types of instructions :- Data Processing instruction Data Transfer instruction Flow control Instruction Data Processing Instruction Data Processing instruction are used for processing of data i.e, they are used mainly for some calculation. The processing operation are again scheduled in two types :- Arithmetical… Continue reading Types Of ARM Instruction

ARM Instruction Execution

The ARM processor follows the Von-Neuman Execution strategy. In this strategy, the scientist followed the load-store architecture i.e, the instruction first store in the memory and execute sequentially.  ARM Instruction Execution The execution Process of ARM instruction execution cycle is 4 phase:- Fetch:- In this phase, the processor fetches the instruction from memory. Decode:- In… Continue reading ARM Instruction Execution

Pipeline System in ARM

The ARM processor uses the Pipeline system to perform parallel processing. Pipeline system in ARM uses an instruction pipeline to execute more than one instruction at a time. By using pipeline processing the ARM processor will reduce the execution time. Pipeline system in arm Generally, the ARM processor will use two pipeline system:- 1. 3… Continue reading Pipeline System in ARM

ARM ARCHITECTURE

ARM stands for Advanced RISC Machine. It is work on reduces instruction set computer. ARM architecture uses load-store architecture to perform different operations. It is a 32bit processor, the word length is 32bit. i.e the size of the register is 32bit. ARM architecture uses a 32-bit address to access memory i.e it can uses 2^32… Continue reading ARM ARCHITECTURE

Instruction Cycle

What is the instruction cycle:- It is defined as a set of sub-cycles states of phases used to execute each and every instruction of a program. The instruction cycle in computer architecture consists of 4 sub-cycle such as  Fetch Execute Interrupt Indirect The instruction cycle in computer architecture is graphically shown as follows Fetch: –… Continue reading Instruction Cycle

Register Organization

The use of register organization make the instruction shorter and faster hence the execution time will be reduced significantly. The use of register used by the processor globally classify into two types such as:- General-purpose Register       2. Control and Status Register 1. General Purpose Register:- It is accessed by the user which is accessed by… Continue reading Register Organization
