Write a short note Central Processing Unit of a computer describing its parts.
CPU is known as Brain of Computer. The central processing unit is responsible for carrying out
the processing job. It is a brain of computer. It has two components Arithmetic and Logic Unit
(ALU) and Control unit (CU). ALU and CU togetherreferred to as CPU of a computer.
Name any one cloud storage you have used?
Google Docs C Microsoft OneDrive
Write down few preventive measures you willtake while using these public cloud services.
➢ Know where your data lives.
➢ Always backup your data.
➢ Make sure your datacentre takes security seriously.
➢ Getreferences from other clients.
➢ Test, Test, Test. Assume nothing
Why doesn’t everyone use an HDD as compared to SSD. Explain by giving differences
between the two.
SSD uses Flash Memory to store data instead of a spinning disk.
SSDs have no moving parts, making them much faster & more durable.
SSDs are less susceptible to mechanical failure than HDDs.
But HDDs are more affordable and may offer easier data recovery in the event of damage.
Memory of computer is —– where data can be stored.
Storage Location
1024 bytes
= 1 Kilobytes (KB)
—-temporarily memorizes data while programs are running whereas —-
stores information over the long term, including after the computer is turned off.
RAM ,Hard Disk
——– is a credit card-sized card with a microprocessor and memory used to hold
customer account information.
Smart Card
—- is a computer storage medium that is a fixed part of the computer’s
hardware. It is a non-volatile storage device which stores digitally encoded data
Hard Disk
Write any two differences between
a. RAM, ROM
RAM is the system’s main memory, i.e. it is a space that allows you to temporarily store
data when a program is running. RAM is volatile, meaning that it only stores data as long
as it supplied with electricity.
ROM is a type of memory that allows you to keep the information contained on it even
when the memory is no longer receiving electricity. Basically, this type of memory only has
read-only access.
b. Primary Memory Secondary Memory
Primary memory or internal memory that temporarily memorizes data while programs are
running. For example RAM.
Secondary or Auxiliary memory (also called external memory) that stores information over
the long term, including after the computer is turned off. For example, CD and Hard Disk.

. The volatile memory of the computer is
RAM
The input device used in games is
s Joystick
. A device which can be used both as a input and output device is
Touch Screen
An optical disk which can store upto 700 MB of data.
Compact Disk
Memory device which has no moving parts, nor does it make use of lasers- unlike optical
drives. Instead, it works in a similar way to RAM
Pen Drive
It looks the same as a compact disc but can hold about 15 times as much information
DVD
It is one of the portable storage devices which enables one to transfer small files between
computers and to store data/information as backup
Pen drive
