10 important and commonly asked
questions from past BCom Computer exams, along with their answers:
Part
1: Basic Computer Concepts
- Explain the difference between hardware and software.
Answer:
Hardware refers to the physical components of
a computer, such as the monitor, keyboard, and motherboard. Software refers to
the programs and applications that run on a computer, such as operating
systems, word processors, and games.
- What are the primary functions of an operating system?
Answer:
The
primary functions of an operating system include managing hardware resources,
providing a user interface, executing and providing services for applications,
and ensuring security and access control.
- Define 'bit' and 'byte'.
Answer:
A bit
(binary digit) is the smallest unit of data in a computer, representing a
single binary value (0 or 1). A byte is a unit of digital information that
consists of 8 bits.
- What is the purpose of RAM in a computer system?
Answer:
RAM (Random Access Memory) is used to store
data and instructions temporarily while a computer is running. It allows for
quick read and write access to a storage medium that is much faster than a hard
drive or SSD.
- Differentiate between system software and application
software.
Answer:
System software includes the operating system
and all utilities that enable the computer to function. Application software
includes programs that perform specific tasks for users, such as word
processors, spreadsheets, and database management systems.
Part
2: Advanced Computer Concepts
- Explain the concept of 'database normalization'.
Answer:
Database
normalization is the process of organizing data in a database to reduce
redundancy and improve data integrity. It involves dividing a database into two
or more tables and defining relationships between the tables.
- What is a computer network, and what are its types?
Answer:
A computer
network is a set of computers connected together for the purpose of sharing
resources. The types of computer networks include LAN (Local Area Network), WAN
(Wide Area Network), MAN (Metropolitan Area Network), and PAN (Personal Area
Network).
- What is cloud computing?
Answer:
Cloud computing is the delivery of computing
services over the internet. These services include storage, databases, servers,
networking, software, and more, providing flexible resources and economies of
scale.
- What are the differences between static and dynamic web
pages?
Answer:
Static web
pages are fixed and display the same content to every user. They are usually
written in HTML and do not change unless manually updated. Dynamic web pages, on
the other hand, are generated in real-time based on user interactions or other
parameters, often involving server-side scripts like PHP or ASP.NET.
- Explain the concept of 'Internet of Things' (IoT).
Answer:
The Internet of Things (IoT) refers to the network
of physical objects embedded with sensors, software, and other technologies to
connect and exchange data with other devices and systems over the internet.
This enables these objects to collect and share data, improving efficiency and
creating new applications and services.
