Chapter 3, Problem 14DQ

Program Plan Intro

Components of computer:

Computer has four major components, they are:

Central processing unit (CPU)

Memory unit

Input devices

Output devices

Central Processing Unit (CPU):

CPU plays the key role in a computer by carrying out instructions of a computer program.

It performs all the basic logic, arithmetic, controlling and input/output operations that are specified by the instructions.

The CPU comprises of two units, Arithmetic logic unit (ALU) and control unit (CU).

Memory unit:

Once computer program instructions set are transformed into machine code by CPU, the machine code is stored in memory.

Then the CPU fetches the required data and instructions from memory, perform the required operations and then sends the result and next set of instructions back to memory.

Input devices:

The devices used by the user to feed information to computer, such as a hard drive, keyboard, or a networking card.

These devices get the data from outside world into computer in the way that human eyes and ears bring the data to brain.

Output devices:

Output devices are used by computer to deliver the information to the user, such as a monitor, printer, and speaker.

The CPU takes the machine code present in memory and converts it into a format that is required by monitor’s hardware.

Then the monitor’s hardware alters that information into different light intensities such that words or pictures are seen.

1. Unsigned Integers If we have an n-digit unsigned numeral dn-1d n-2...do in radix (or base) r, then the value of that numeral is n−1 r² di Σi=0 which is basically saying that instead of a 10's or 100's place we have an r's or r²'s place. For binary, decimal, and hex r equals 2, 10, and 16, respectively. Just a reminder that in order to write down a large number, we typically use the IEC or SI prefixing system: IEC: Ki = 210, Mi = 220, Gi = 230, Ti = 240, Pi = 250, Ei = 260, Zi = 270, Yi = 280; SI: K=103, M = 106, G = 109, T = 10¹², P = 1015, E = 10¹8, Z = 1021, Y = 1024. 1.1 Conversions a.
