Frequently Asked Questions

Q1: What is the function of computer?

A1: The basic function performed by a computer is execution of a program, which consists of a set of instructions stored in memory.

function of computer

Q2: What is a bit?

A2: Bit is usually a shortened form of “Binary digit”. It is common to avoid or neglect the fact that a bit represents the state of a switch. Hence simply call the switches as “bits.” A bit represents the state of an on-off switch.Using bits (binary digits), we can greatly simplify the previous statement about switches as 1101, which you can think of as representing “on, on, off, on.”. While representing, it does not matter whether we use 1 to represent “on” and 0 as “off,” or 0 as “on” and 1 as “off”. Everyone simply needs to be consistent.

Q3: What is a bus?

A3: A bus is a communication pathway connecting two or more devices. Shared transmission medium is a a main characteristic of a bus. A bus will be connected by multiple devices. A signal transmitted by any one device will be available for reception by all other devices attached to the bus. In case, if two devices transmit during the same time period, their signals will overlap and become distorted. Therefore, only one device can successfully transmit at a time . Generally, a bus consists of multiple communication lines or pathways. Each pathway is capable of transmitting signals representing the binary 1 and the binary 0. An 8-bit unit of data will be transmitted over eight bus lines. A system bus  connects major computer components (processor, memory, I/O).

Q4: What is the difference between Minimal sum of products (mSoP) and minimal product of sums (mPoS)?

A4: Minimal sum of products (mSoP): A sum of products expression is minimal if all other mathematically equivalent SoPs
1. have at least as many product terms, and
2. those with the same number of product terms have at least as many literals.
Minimal product of sums (mPoS): A product of sums expression is minimal if all other mathematically equivalent PoSs
1. have at least as many sum factors, and
2. those with the same number of sum factors have at least as many literals.

These information imply that there can be more than one minimal solution to a problem.
