Q1 ans: - “The best interface for a system is no users interface” is mainly referred as the
process in which data or information is input directly from the source computer to the destination
systems without users interface or communication. In computer system users mainly serves two
objectives (excluding entertainment application) and they are - 1) inserting the input data into
computer, and 2) offering information for human decisions (Shneiderman, 2010). No interface is
the best interface concept in computer world is achieved with the help of IOT (internet of things
technology). In this concept, client may only get involved when they are needed.
KEYLESS-GO (LOCK/UNLOCK) - Mercedes-Benz USA uses this concept and with this
concept the organisation (automaker) has eliminated the user interface. A few organizations
such as Google also implement this concept in their Smartphone applications that permits
customers to pay merchants with use of NFC.

Twisted pair cables: - Twisted pair cable is mainly common type of cable made by the
intertwining two different type of insulated wires. UTP (unshielded twisted pair) and STP
(shielded twisted pair) are two types of twisted pair cables mainly used to transfer the data and
information from source to the destination (Green, 2012).
Categories of twisted pair
categories Application &features
cat 1 It is used in modem and telephone lines.
Bandwidth of cat 1 is 0.4MHz. The data
transfer rate of cat 1 is up to 1Mbps.
cat 2 Cat 2 mainly implemented in token ring
networks and its data transfer rate from source
to destination end is up to 4 Mbps.
cat 3 It is mainly implemented in 10BASE-T
Ethernet and it covers maximum rate 100
meter. The data transfer rate is up to 10 Mbps
(Evans, Martin & Poatsy, 2010).
Coaxial cable:- Coaxial cable are durable, heavy cable used for several types of commercial and
residential installations. The main application of the coaxial cable is to transfer video signals. A
coaxial cable is manufactured with the copper clad steel center conductor or solid copper
surrounded by the non conductive insulating materials.
