Long
answer questions.
Question
1: What do you mean by generations of computers? How are they divided?
Answer: In
computer technical terminology, a generation means a change in computer
technology. Computer generations are classified into five generations as
follows:
1. First
generation computers (1942-1955):- The first generation was from 1942-1955. The first
generation computers used vacuum tubes as the main part for the memory and
circuitry for the hidden central processing unit. These tubes, like electric
bulbs, produced a lot of heat.
2. Second
generation computers (1955-1964):- The second generation of computers was from 1955-1964.
Transistors were used as the basic processing components in this generation of
computers. The computers of this generation were cheaper, less power-consuming,
smaller in size, more reliable and faster than the machines of the first
generation.
3. Third
generation computers (1964-1975):- The third generation of computers was from 1965-1971.
Transistors were mainly used to develop computers in the second generation of
computers, but integrated circuits were introduced in the third generation of
computers. Jack Clybe was the founder of integrated circuits. Many single
transistors, capacitors and resistors can be used in place of transistors in a
single integrated circuit.
4. Fourth
generation computers (1975-1989):- The fourth generation of computers was between 1971-1980.
These computers used Very Large Scale Integrated (VLSI) circuit technology.
Hence they were also known as microprocessors. Intel was the first company to
develop microprocessors. The first "personal computer" or PC,
developed by IBM, belonged to this generation.
5. Fifth
Generation Computers (1989 - Present):- This is the current generation of computers and is the most
advanced. This generation started around 1989 and is the current generation of
computers. ULSI (Ultra Large-Scale Integration) technology is used in the fifth
generation. These ULSI microprocessor chips have ten million electronic
components. Input methods include modern high-level languages like Python, R, C#.
Question
2: Explain the fifth generation computers?
Answer: This
is the current generation of computers and is the most advanced. This
generation started around 1989 and is the current generation of computers. ULSI
(Ultra Large-Scale Integration) technology is used in the fifth generation.
These ULSI microprocessor chips contain tens of millions of electronic
components. Input methods include modern high-level languages like Python, R, C#. These computers
are at the cutting edge of modern scientific computation and are used to
develop artificial intelligence or AI components that have the ability to think
for themselves.
Features
of Fifth Generation Computers:-
1. Fifth
generation computers use the same technology that includes: development of
expert systems, gaming, robotics, natural language understanding, and neural
networks.
2. The same
technology has made these computers capable of understanding human language as
well as recognizing graphs and images.
3. The
development of fifth generation computers aims to solve very complex problems,
including working with natural language.
4. These
computers are very easy to move from one place to another and to repair.
5. Computers
made in the fifth generation can be easily maintained.

Short
Answer Questions.
Question
1: What is memory?
Answer:
Computer memory is like the human brain. It is the storage area of the computer in which data and
instructions are stored. Computer memory is divided into many small parts,
called cells. Each cell has a unique memory address.
Question
2: Name the different types of memories?
Answer:
Memory can be divided into two main parts:-
1. Internal
memory
2. External
memory
Question
3: What is primary memory?
Answer:
Primary memory is the memory that the CPU has direct access to. The computer
cannot start without this memory. This memory is located on the motherboard of
the computer near the CPU. The CPU can read data from these memories very
quickly. This memory is faster than secondary memory but slower than registers
and cache memory. There are two types of primary memory, RAM and ROM.
Question
4: Write the names of different types of ROM?
Answer:
Names of different types of ROM:-
1. Masked
ROM
2.
Programmable ROM
3. Erasable
and programmable ROM
4.
Electrically erasable and programmable ROM
Long
answer questions.
Question
1: Describe RAM and ROM?
Answer: RAM:-
RAM is volatile memory, which means that the information temporarily stored in
the module is erased when you restart or turn off your computer. Since the
information is stored electrically on transistors, when there is no electric
current, the data disappears. Every time you request a file or information, it
is retrieved from the computer’s storage disk or the internet. The data is
stored in RAM, so every time you switch from one program or page to another,
the information is immediately available. When the computer is turned off, the
memory is cleared until the process is started again. Volatile memory can be
easily replaced, upgraded or expanded by users.
ROM:- ROM is volatile memory, which means
that the information is permanently stored on the chip. Memory does not rely on
an electric current to store data; instead, data is written to individual cells
using binary code. Permanent memory is used for parts of a computer that do not
change, such as the initial boot-up portion of software, or the firmware
instructions that run your printer. Turning off the computer does not affect
ROM. Permanent memory cannot be changed by users.
Question
2: Explain external memory?
Answer:
External memory is also called secondary or auxiliary memory or permanent
memory. It is used to store data and information permanently. These memories
cannot be accessed directly by the CPU. They are accessed through input/output
routines. The data in secondary memory is first sent to main memory, then the
CPU can access this data. Some examples of secondary memory are CD-ROM, DVD,
HARD DISK etc.
Question
3: Describe the characteristics of secondary memory?
Answer:
Characteristics of secondary memory:-
1. It is a
magnetic and optical type of memory.
2. Data is
stored permanently in secondary memory until something else is written on it or
it is erased by the user.
3. Data is
stored permanently in this memory even when the power is turned off.
4. Due to
the high physical stability of secondary storage devices, data remains safe in
them.
5. With the
help of computer software, authorized users can quickly find and use the data.
6. Secondary
storage can store a lot of data in multiple sets of disks.
7. Storing
data on magnetic tape or disk is much cheaper than primary memory.
8. The
computer can start without secondary memory.
9. Its speed
is faster than primary memory.
Question
4: What are tracks and sectors?
Answer: The
smallest unit that can be accessed on a disk. When a disk undergoes a low-level
format, it is divided into tracks and sectors. Tracks are concentric circles
around the disk and sectors are segments within each circle. For example, a
formatted disk may have 40 tracks, each track divided into 10 sectors. The
operating system and disk drives keep tabs on where information is stored on
the disk by noting its track and sector number.
Question
5: What is cache memory? Write its advantages and disadvantages?
Answer:
Cache memory is a special and very high-speed memory. Cache memory is more
expensive than main memory or disk memory, but more economical than CPU
registers. Cache memory is a type of very fast memory that acts as a buffer
between RAM and the CPU. It holds frequently requested data and instructions so
that they are immediately available to the CPU when needed. Cache memory is
used to reduce the average time to access data from main memory.
Advantages
of cache memory:-
1. It is
faster than main memory.
2. Access
time is much less compared to main memory.
3. The speed
of accessing data increases, so the CPU works faster.
4. Apart
from this, the performance of the CPU also improves.
5. It stores
the current data in cache memory and so that it can be used when needed.
Disadvantages
of cache memory:-
1. It is
quite expensive.
2. Storage
capacity is limited.
