Investigating the difference between a single wire and multiple wire

1. Investigating the difference between a single wire and multiple wire By Ali, Ismail, George, Babalola and Abdullah

2. Intro • What is a single wire A single wire transmission is a way of transmitting electrical power or signals by only sing a single electrical conductor, this is in contrast to the usual use of a pair wires providing a complete circuit, or a cable likewise containing two conductors for that purpose. The system relying on the return current through the ground, using the earth as a second conductor, they are rather termed single wire earth return. • What is a multiple wire A multiple wire is a wire that dos the same thing as a single wire but the multiple wire is placed in series, multiple wires is much faster.

3. Register WAYS OF DEFINING A REGISTER; Registers are data storage devices that are more sophisticated than latches. A register is a group of binary cells suitable for holding binary information. They store related bits of information. There are different types of registers. There are two different types of registers. • SR Register In some situations it may be desirable to dictate when the latch can and cannot latch. The gated SR latch is a simple extension of the SR latch which provides enable line which must be driven high before data can be latched. Even though a control line is now required, the SR latch is not synchronous, because the inputs can change the output even in the middle of an enable pulse. • D Register The D latch (D for "data") or transparent latch is a simple extension of the gated SR latch that removes the possibility of invalid input states. Since the gated SR latch allows us to latch the output without using the S or R inputs, we can remove one of the inputs by driving both the Set and Reset inputs with a complementary driver: we remove one input and automatically make it the inverse of the remaining input.

4. Pocket Zoom Pocket zoom is a process in which stored data is transmitted to discrete units, these units are called pockets. This makes more efficient use of channel capacity and reliability of transfer

5. Serial Data Serial data is a form of data transmission where by bits of characters is deployed one at a time along a communication path. Serial data transmissions travel over a single wire in one direction and are often compared to data transmission. They each follow an 8 bit character.

6. Parallel Data Parallel data transmission occurs when several bits of a data item are transmitted simultaneously each along its own separate channel. If a data item is represented by seven bits, there must be seven distinct channels between the sender and receiver

7. Protocol Protocol is a set of rules shared between sender and receiver so that the data knows where to go and when the bytes start and stop. It communicates what programming are to be calculated.
