K is short for Kilo, meaning one thousand. When describing the size of computer memories, how many bytes are available in a 2K machine? The word size of a microprocessor determines the amount of memory that the processor can access. How much memory can be accessed by a microprocessor with a word size of 8? In binary count from zero to ten Inside a computer, you will find a central processing unit (CPU) and main memory, Name two major parts of the CPU. A computer\'s main memory is often referred to as Random Access Memory (RAM). what is meant by accessing memory randomly? Is there a better way to describe how memory is accessed?

Solution

A ) generally, capacity of memory is measured in bytes and it is given in the format 2^X, so a computer with 2k will have 2^11 = 2048 bytes of memory

B) Generally, the word size of a processor will determine the amount of memory the processor can acess, actually word size is defined as the maximum size of a instruntion that a processor can execute, suppose if processor is a 32-bit architecture that means each instruction in the processor is exactly 32-bits and it can address as many as 2^32 =  4,294,967,296 bytes of memory, or 4 gibibytes (GiB). so , similary if the word size is 8 then it can address to maximum of 2^8 = 256 bytes of memory

c) computers can only understand bits 1 and 0 and this language is called as binar language or base-2 system

to write a base -10 number to binary, we write the given integer in powers of 2 .

Binary numbers from zero to ten

0 ------- 0

1 ------- 01

2 ------- 10

3 ------- 11

4 -------- 100

5 -------- 101

6 -------- 110

7 -------- 111

8 ------- 1000

9 -------- 1001

10 ---------- 1010

d )

CPU is called as the brain of the computers, where all the major calculations and the logic manipulations takes place, the CPU stands for central processing unit, which has mainly two parts namely :

ALU (Aithemetic and Logical unit)

CU ( control unit)

ALU as the name itself indcates, deals with arithemtic and logical operations .

The control unit (CU), extracts instructions from memory and decodes and executes them, calling on the ALU when necessary.

e)

In earlier days of computer invention and memory discovery, to access data at a particular byte we have to touch all the preceding bytes before them to reach our destiation that makes access time slower and data becomes vunerable, to avoid this memories which can be accessed randomly have been introduces, that means each and every byte of a random accessable memory(RAM) can be acccessed without touching any other byte, that is we can access memory randomly which is why this memory is give the name \"Random accessable memory \" .
