<span>This is called an unshielded twisted pair cable, which is also known as a UTP cable. This type of cable has four pairs of wires that are twisted around each other. Because the wires are like this, the electrical interference is reduced.</span>
An embedded computer is a product that uses a microprocessor as a component. Ie a relationship between a car and its engine. A Microcontroller is a microprocessor that is packaged with RAM, program storage and interface circuitry to make it simple to use
Answer:
Direct data access reduces the speed of retrieving data from memory or storage. Retrieving data and storing it in a cache memory provides direct access to data in the storage.
Explanation:
Sequential memory access, as the name implies, goes through the memory length location in search of the specified data. Direct memory access, provides a memory location index for direct retrieval of data.
Examples of direct and sequential memory access are RAM and tapes respectively. Data in sequential memory access can be access directly by getting data in advance and storing them in cache memory for direct access by the processor.
Answer:
3 select inputs are required to select a specific input between 5 inputs.
Explanation:
Multiplexer is used to select the inputs from different inputs to a single output. There are many types of multiplexers for different number of inputs selection. 1. 2x1 is the type of multiplexer where 2 inputs and 1 output. This is used to select between these inputs. There is one more pin to select the input between these two inputs that is called <em>select </em>input.
2. Another type is 4x1 multiplexer. There are 4 inputs and one output. In this type of multiplexer 2 select pins are used for selection of input bits between these 4 inputs.
For more than 4 inputs and less than 8 inputs, 8x1 multiplexer is used. this multiplexer uses three inputs for selection purpose.
