💥 What is the use File Management Program? Explain.
File Management Program manages the files and folder on a computer system.
Every time you create a document, the first steps is to save it as a file. You can retrieve the file latter and can be stored on an internal or external storage device like CD, DVD, Pen drive, etc.
💥 What is utility program? Give example.
Utility program is designed to perform maintenance work on a system or on system components.
Example of utilities are File management program, Virus Scanner/ Cleaner programs, and Encryption.
💥What is a cache memory?
This is a very special type of high-speed memory that cannot be accessed by the user. The main function of this cache memory is to make programs and data available to the CPU very fast.
💥 Name the three types of buses of computer?
The three main buses of computer are:
i) Data bus: It carries data from the memory to the CPU and form the CPU to the memory
ii) Address Bus: It caries address from the CPU to the memory.
iii) Control bus: It carries instructions between the CPU and other parts of the computer.

Buffer is a section of computer memory where data is stored before being used.
💥 What is output? (Any one you can write)
The result produced by the computer is known as output.
OR
The final result given by the computer after processing is called output
💥 When was the first OMR sensor created?
The first OMR sensor was created by IBM in 1930’s.
💥 What is the smallest unit of computer memory?
bit is the smallest unit of computer memory.
💥What is Package?
A package is a computer application consisting one or more program created to perform a particular type of work.
💥 What is encryption and decryption?
Encryption is a process that convert data into coded form in order to prevent an unauthorized user from reading it. Where as, Decryption is a process that converts coded data to readable form.
💥 What is computer language?
A computer language is a "language" made up of formal syntax and semantics that allow users to communicate instructions to computer systems.
💥 What is a Syntax?
Syntax is the set of rules that define what the various combinations of symbols mean. This tells the computer how to read the code. Syntax refers to a concept in writing code dealing with a very specific set of words and a very specific order to those words when we give the computer instructions.
2. Long answer question:
a. What is secondary memory? Describe the main two types of secondary
memory?
Secondary memory is computer memory that is persistent in nature and is
not directly accessed by a computer or processor. It allows a user to store
data that may be instantly and easily retrieved, transported and used by
applications and services. Secondary memory is also known as secondary storage
or a mass storage.
The
main two types of Secondary memory are:
i) Magnetic media: Any storage
medium that utilizes magnetic patterns to represent information is considered
magnetic media. Good examples of a magnetic media and magnetic storage is a tape
drive, floppy diskette, and hard drive.
ii) Optical Media: Optical media
refers to any data storage device or equipment that uses optical data storage
and retrieval techniques to read and write data. It stores data digitally on a
media device and uses a laser to read data from it. Optical media is also known
as optical storage. Example- CD, DVD and Blu-Ray disc etc.
b. Write short notes on each of the three types of computer languages.
The
three types of computer languages are:
i) Low Level Language: It is a machine
dependent language which offers few control instructions and data types. Each
statement in a program written in a low-level language usually corresponds to
one machine instruction.
ii) Assembly Language: Assembly
language is designed mainly to replace each machine code with an understandable
mnemonic code. To execute an assembly language program, it should be first
converted into an equivalent machine language program.
iii) High level language: High level
language is developed to create application programs which are not dependent
upon machines. It permits the user to understandable codes, using the language
structure. In order to execute a high-level language program, it should be
translated into machine language either using a compiler or an interpreter.
The three parts of a computer system are:
i) Input Unit: This part of computer system
takes an input from an input devices in the form of data’s and instructions
then it convert the data’s into binary forms 0 and 1, so that it is
understandable by the computer system.
ii) Central Processing Unit: This part is
the brain of a computer where all processing are done. It consist of the
processing unit and storage unit. The processing unit again consists of the ALU
that perform all mathematical and logical operation, Control unit that control
the flows from input device to the memory and from memory to the output
devices.
iii) Output: The output unit comprises of the output
devices attached to the computer which convey information to the user. Some of
the output devices are VDU, EGA, VGA, SVGA, Printers and Plotters
d. What is system software? Classify the software and explain its types
giving suitable examples.
System Software is a set of one or more programs designed to control the
overall operation of a computer system.
The systems software is classified in to:
i) Operating System: An operating
system is a software program that enables the computer hardware to communicate
and operates with the computer software. It controls the flow of signals from
the CPU to various parts of the computer. Examples: Windows, LINUX, MACOS, UNIX
etc.
ii) Assembler: An assembler is a program
that converts an assembly language program into machine language program. Each
language is usually converted into one machine instruction.
iii) Compiler: A compiler is a software
program that compiles machine language instructions for every program’s
instruction of high-level language. It is a program translator and scans the
entire program first and then translate it into machine code. The translation
process is called compilation.
iv) Interpreter: An interpreter is a program that translate one statement of high-level language program into machine code and then execute it.
e. Write a short note on Cache memory.
💥 What are general purpose application software? Give examples.
General purpose application software is designed to solve a wide range of task. Examples of such software are as follows:
i) Word-processing software: MS Word (Used for manipulating text).
ii) Spreadsheet Software: Microsoft Excel (Use for finance-related tasks and data).
iii) Presentation software: Microsoft PowerPoint (Use for creating slide show presentation).
iv) Database management software: Microsoft Access (Use for working with records).
💥 What are the strength of the computer?
The strength of the computer are:
i) High speed
ii) Reliability and Accuracy
iii) large memory
iv) Logical decision making
v) Versatility
vi) Automation
vii) Diligence
💥 What are the limitation of computers?
The limitation of computers are:
i) Lack of common sense: a computer is designed in such a way that it works only logic and not on common sense.
ii) Zero IQ: Computer do not have the ability to think and understand.
iii) No feeling: No matter how long the computer works, it does not affect the speed of a computer work nor does the computer ever feel tired.
iv) Computer can’t decide: Computer do not have the ability to make decision.
💥 What are the basic applications of computer?
Computer play a role in every field of life. They are used in home, business, educational institution, research organization, medical field, government offices, entertainment, etc.
💥 What are the purpose of primary memory?
The purpose of primary memory are:
i) It holds both data and programs that are in current use by the CPU.
ii) Primary storage devices are extremely fast and so the CPU can run at top speed.
iii) As input storage area, where data is fed and held until ready to be accessed.
iv) As a program storage area to hold the processing instructions.
