TRICKS TO CRACK FIRST PAPER:   

                            M1-R4: IT TOOLS & BUSINESS SYSTEMS

     

        SOME IMPORTANT TOPICS WHICH FREQUENTLY ASKED EVERY            YEAR:--



HIGH LANGUAGE VS LOW LEVEL LANGUAGE---
High Level Languages
High level languages are written in a form that is close to our human language, enabling to programmer to just focus on the problem being solved.
No particular knowledge of the hardware is needed as high level languages create programs that are portable and not tied to a particular computer or microchip.
These programmer friendly languages are called ‘high level’ as they are far removed from the machine code instructions understood by the computer.
Examples include: C++, Java, Pascal, Python, Visual Basic.
Advantages
  • Easier to modify as it uses English like statements
  • Easier/faster to write code as it uses English like statements
  • Easier to debug during development due to English like statements
  • Portable code – not designed to run on just one type of machine
Low Level Languages
Low level languages are used to write programs that relate to the specific architecture and hardware of a particular type of computer.They are closer to the native language of a computer (binary), making them harder for programmers to understand.
Low level refers to:
  • Assembly Language
  • Machine Code
Assembly Language
Few programmers write programs in low level assembly language, but it is still used for developing code for specialist hardware, such as device drivers.It is easy distinguishable from a high level language as it contains few recognisable human words but plenty of mnemonic code.

Advantages
  • Can make use of special hardware or special machine-dependent instructions (e.g. on the specific chip)
  • Translated program requires less memory
  • Write code that can be executed faster
  • Total control over the code
  • Can work directly on memory locations

What is macro in ms word:-

In Word, you can automate frequently used tasks by creating and running macros. A macro is a series of commands and instructions that you group together as a single command to accomplish a task automatically.
To save time on tasks you do often, bundle the steps into a macro. First, you record the macro. Then you can run the macro by clicking a button on the Quick Access Toolbar or pressing a combination of keys. It depends on how you set it up.

There are two MTAs  client  MTA and  server  MTA. A  client  MTA at clients system sends mail which is received by the  server  MTA at client’s mail server. Further, the client mail server has  client  MTA which sends the mail from client’s mail server to the  server  MTA at recipient’s mail server.  SMTP is a protocol that defines both client-server MTA, on the internet. SMTP protocol is used in the scenario where both the  sender  and  receiver  of mail must be connected to their mail server by  WAN or LAN . SMTP protocol is used two times,  first  between  sender and its mail server  a...
