---


B. Fill in the blanks.


1. Machine language is the only language that a computer understands.

2. Assembly language is regarded as the second generation language.

3. A program converted into machine language by a translator is called object code.
(Note: "Assembler" is the translator, not the output.)

4. A/An interpreter converts a high-level language program into machine language line-by-line.

5. Prolog is an 
example of fifth generation language.


C. Write T for True and F for False:


1. A program is a set of instructions.
T

2. The development of computer languages is classified into two categories.
F (It is classified into five generations.)

3. Assembly language consists of binary numbers, 0s and 1s.
F (Assembly uses mnemonic codes, not binary numbers.)

4. Machine language uses simple English words and phrases.
F (It uses binary code — 0s and 1s only.)

5. The ultimate aim of 5GLs is to make computers think and react 
as human beings.
T


D. Answer the following questions (Short Answers):


1. What is a programming language? Define machine language.
Ans:
A programming language is used to give instructions to a computer.
Machine language is the only language computers understand. It uses 0s and 1s.


2. What are the advantages of assembly language?
Ans:
Easier to understand than machine language
Uses short words (mnemonics)
Easy to find and fix mistakes


3. What is the difference between source code and object code?
Ans:
Source code is written by the programmer.
Object code is the computer version made from the source code.


4. What is a translator? How is an interpreter different from a compiler?
Ans:
A translator changes code into machine language.
A compiler changes the whole program at once.
An interpreter changes it one line at a time.


5. What are the features of fifth generation languages?
Ans:
They use Artificial Intelligence (AI)
Help computers think and solve problems
Example: Prolog

 Hey, friends today we will learn and discuss about C programming language.  C programming is one of the most powerful languages available in the world of technology.  So without wasting any time let's go on the notes.  In this page I write C-programming as the father of all computer language because after the development of C the world of technology starts growing rapidly.  C-language is one the the fastest programming language available.  In this page I discussed about the history of C language and the reasons why c is widely used.  Basically there was a time when C language is the only using programming language in the development of Operating system and also, in the development of other applications.  In second page I discussed about the " Important things to know about C language "  and "Why we have to learn C? " In this page we discussed about how we setup our laptop or desktop to code in C language.  In this I also clear abou:-...

All about hacking.

  The past few decades have seen a very rapid increase in the number and scope of security lapses. Hacking has emerged as perhaps the most serious form of such break-ins, with attacks that can extend globally. Introduction: With technologies advancing at an exponential pace, hacking has become a severe threat unsolved by today's data defenses against cyber-attacks. Introduction: Society is yet to find ways to deal with cybersecurity challenges. What is needed is a comprehensive strategy that integrates human intelligence and machine learning with technology alone. — Cyber hacking is a type of unauthorized digital access to information. It can either be internal or external. Internal hackers are people that work within the company and are seeking to steal company information, such as trade secrets. External hackers are people that seek out and exploit vulnerabilities related to the Internet, such as computer viruses, search engine optimization, or theft of email messages. The use ca...
