Low-level language: these are coded in a form which is easy to understand by the processor.

 

Machine language:    it is also a type of low-level language these can be developed in binary language (0 and 1).

 

Assembly language:  it is also a type of low-level language and using the human readable instruction of the CPU. It is written as ‘MOV A.’

 

High-level language programmer can write code in the simple easy language, it is user-friendly. E.g. C, JAVA

 

C language: it is a middle-level programming language and also known as procedural language

C++ is high-level language that uses the OOPS concept.

Fortran:   it is known as formula translation. It is used for scientific application

 

COBOL (Common Business Oriented Language ): used for record keeping and data management in business organizations.

 

BASIC (Beginner’s All-Purpose Symbolic Instruction Code): first language designed for non-professional programmers.

PASCAL: it is developed as a teaching tool for programming concepts.

 

Simula was the first object-oriented programming language. Java,  Python, C++,  Visual  Basic.NET  and  Ruby are the most popular Object Oriented Programming languages. The Java programming language is designed especially for use in distributed applications on corporate networks and

the Internet. Ruby is used in many Web applications. Curl, Smalltalk, Delphi, and Eiffel are also examples of object- oriented programming languages.

 

Language processor   (Translator):   Programmers write their program in one of the high-level languages because it is much easy to code in this language but a computer does not understand any  of these  language so  it is  necessary to convert the program into a machine language so translator does this work.

 

Loader: It loads the code which is translated by translator into the main memory and makes it ready to execute.

 

The linker is used to combining all the object files and convert them into a final executable program.

 

The interpreter converts high-level language program into machine language. It is very slow because it converts program line by line.

Compiler: It also  translates the program  from high  level language to machine language. It is very fast because it converts the whole program into machine language.

 

Assembler: It is used for converting the code of low-level language (assembly language) into machine level language.

A group of 4 bits is called a nibble. A byte is also known as an Octet.

Primary Storage (memory), also known as the main storage and it is the area in a computer in which data is stored for quick access by the computer’s processor. The terms random

access memory (RAM) and memory are often as synonyms

for primary or main storage. Primary storage is volatile and can be contrasted with non-volatile secondary storage, also known as auxiliary storage.

Cache memory is a  smaller, faster memory which stores copies of  the data  from frequently  used main  memory locations.  A  CPU  cache is  a  hardware cache  used by  the central processing unit (CPU) of a computer to reduce the average time to access data from the main memory. Secondary memory is where programs and data are kept on a long-term basis. Common secondary storage devices are the hard disk and optical disks. The hard disk has enormous storage capacity compared to main memory. The hard disk is usually contained inside the case of a computer.

Read-only memory (ROM)  is a  storage medium used in computers and other electronic devices. Data stored in ROM can only be modified slowly or with difficulty, or not at all.

 

ROM  is non-volatile and the  contents are  retained even after the power is switched off.

It only allows reading.

The types of ROM include PROM, EPROM, and EEPROM. PROM  –  (programmable read-only memory) is a  memory chip on which data can be written only once.

 

The difference between a PROM and a ROM (read-only memory) is that a PROM is manufactured as blank memory, whereas a ROM is programmed during the manufacturing process. To write data onto a PROM chip, you need a special device called a PROM programmer or PROM burner.

EPROM – (erasable programmable read-only memory) is a special type of PROM that can be erased by exposing it to ultraviolet light.

EEPROM  –  (electrically  erasable  programmable  read-only

memory). EEPROM is a special type of PROM that can be erased by exposing it to an electrical charge.

 

Random Access Memory (RAM), allows the computer to store data for immediate manipulation and to keep track of what is currently being processed.

 

RAM is referred to as volatile memory and is lost when the power is turned off.

It also is known as reading/write memory as information can be read from and written onto it.

The two main types of RAM are Static RAM and Dynamic RAM.

 

SRAM retains data as long as power is provided to the memory chip and need not be refreshed periodically. It is often used as CPU Cache memory. SRAM stands for Static Random Access Memory.

 

The data  on  DRAM continues to move in and  out of  the memory as   long as   power is   available and   must be continually refreshed to maintain the data. DRAM stands for Dynamic Random Access Memory.

 

Virtual memory is the memory on the hard disk that the CPU uses as an extended RAM.

Memory  can  also  be  categorized  on  the  basis  of  their material:

 

Semiconductor memory: –such as RAM, ROM, EPROM, and flash memory.

 

Magnetic memory: –such as  hard disk,  floppy disk , and magnetic tapes.

 

Optical memory: –such as computer disk, DVD, and blue-ray disk.

A bus, in computing, is a set of physical connections (cables, printed circuits,  etc.)  which can  be shared  by multiple hardware components in order  to communicate with one another.

The address  bus   (sometimes called  the memory  bus) transports memory addresses which the processor wants to access in order to read or write data. It is a unidirectional bus.

 

The data bus transfers instructions coming from or going to the processor. It is a bidirectional bus.

The control bus (or command bus) transports orders and synchronization signals coming from the control unit and traveling to all other hardware components. It is a bi-directional bus, as it also transmits response signals from the hardware.

computer questions and answers

The radix or base is the number of unique digits, including zero, used to represent numbers in a positional numeral system. For example, for the decimal system, the radix is ten because it uses the ten digits from 0 through 9. And that of Binary is base 2.

Number System

Decimal, Binary, Octal and Hexadecimal

Equivalents

Decimal          Binary            Octal        Hexadecimal
0                    0000               000                      0
1                    0001               001                      1

Hexadecimal to Binary: Refer the above table for the conversion process

(1A2)16 = (?)2

1=0001,      A=      1010,      2=0010;      Hence      (1A2)16          = (000110100010)2

Decimal to Binary: (75)10 =(?)2

Divide 75 by 2 (and write down its remainder).

to decimal:

Sum of all (Digit × (Base)Base’s Place)

Example: (1A2)16 = (?)10  (From the table you can refer A is equivalent to 10)

((1× 162)+(10 × 161)+ (2×160))= 256+160+2=418

Example: (110110)2=(?)10

((1×25)+          (1×24)+          (0×23)+          (1×22)+          (1×21)+

(0×20))=32+16+4+2= 54; (110110)2=(54)10

Octal  to  Binary:  (345)8   Hence (75)10 =(101011)2

Any number system =(?)2   (Write  down  3  bit  binary equivalents of all digits)

3=011, 4=100, 5=101; Hence (345)8 =(011100101)2

Octal  to  Hexadecimal:  Convert  to  Binary  first  and  then

group 4 bits to get hexadecimal number. Example: (345)8

=(?)16 =>(345)8 =(011100101)2 = 0000 1110 0101 =(0E5)16
