Module 2 - Lesson 3: Processing and Storage Devices

Question 1

Is the one responsible for processing and converting data from input to output. Its primary function is to perform arithmetic and logical operations on data taken from the primary storage or on information entered through any input device.

Answer 1

Central Processing Unit (CPU)

Question 2

Is where the instructions and
data are stored while processing

Answer 2

Main memory (also called primary storage)

Question 3

Two types of storage in the Main memory

Answer 3

RAM and ROM

Question 4

Is the part of the memory the computer uses to store volatile data. These are the given instructions that can be changed or erased later.

Answer 4

Random Access Memory (RAM)

Question 5

When data are loaded or put in the RAM, it means?

Answer 5

Writing data

Question 6

When anything access data from the RAM, it means

Answer 6

Reading data

Question 7

Stores the given instructions for the routine operations of a computer. This part is non-volatile; it still holds the instructions even when there is a power interruption or shut-off. From the name, we can only read the information or instructions stored.

Answer 7

Read-Only Memory (ROM)

Question 8

Are temporary storage locations. These are fast-accessed during computer processing. Bits and bits of information from the main memory and those stored back in the main memory are temporarily stored here while
performing computations

Answer 8

Registers

Question 9

Performs all the arithmetic and logical calculations of the CPU. The arithmetic operations consist of addition, subtraction, multiplication, and division. Logical calculations involve comparisons of two or more numbers

Answer 9

Arithmetic Logic Unit (ALU)

Question 10

Is the part of the processor that acts as a traffic controller
for the flow of instructions in the main memory. It’s functions are: controls input and output device, passes data to the ALU for computation, and, most importantly, fetches the instructions from the main memory for execution in the
CPU.

Answer 10

Control Unit (CU)

Question 11

Are bundles of tiny wires that serve as the communication path between components of the CPU.

Answer 11

Buses

Question 12

The three most essential buses are:

Answer 12

Data, Address, and Control Buses

Question 13

Stores data permanently. It is outside the primary storage
and server, just like a filing cabinet. It provides cheap, non-volatile high capacity
storage

Answer 13

Secondary Storage

Question 14

Two classes of secondary storage are:

Answer 14

Direct access media and Sequential Access Storage Device (SASD)

Question 15

Supports sequential or random access where data can be accessed directly, unlike the SASD

Answer 15

Direct access media

Question 16

It accesses data in a specific order

Answer 16

Sequential Access Storage Device

Question 17

Is a sequential access storage media that stores blocks of data
along the length of its tape. Just like any sequential storage media, accessing data is serial. It is a traditional medium that is round, robust, high-capacity, and the cheapest storage medium. It is still famous for its long-term storage. High volume storage even though it is the slowest in terms of retrieval of data.

Answer 17

Magnetic tape

Question 18

Is a direct access storage media, which, like a phonograph record, is divided into tracks and sectors. Common types include hard drives and floppy disks.

Answer 18

Magnetic Disk

Question 19

Are stacks of permanently mounted rigid magnetic disks in a computer unit, be it internally or externally. We often use these as virtual memory or extension of RAM. Have a relatively high capacity and fast retrieval speed but very fragile.

Answer 19

Hard Disks

Question 20

Uses integrated circuit assemblies as memory to store data persistently, typically using flash memory

Answer 20

Solid-state drive (sometimes called solid-state device or solid-state disk)

Question 21

Which is faster SSD or HDD

Answer 21

SSD

Question 22

Are already obsolete and are much slower than hard drives and have a minimum storage capacity only. It is ranging from 1.44 Mb to 200 Mb. Bigger storage capacity for floppy disks is called zip disk, which has a size of 120 Mb.

Answer 22

Floppy disks

Question 23

Are rigid disks of plastic onto which data is recorded by
specialized lasers that physically burn pits into the disc

Answer 23

Optical Drive

Question 24

Is a non-erasable disk that
stores computer data, usually in the standard system, with a 12-cm diameter with CR Recordable (CD Writer), can write data on the disk only once.

Answer 24

CD-ROM (Compact Disk - Read Only Memory)

Question 25

You can erase and rewrite data on the disk up to 1,000 times using the:

Answer 25

CD-Rewritable

Question 26

A hybrid between the magnetic disk and optical disk, uses optical technology for reading and magnetic recording
techniques assisted by optical focusing.

Answer 26

Magneto-Optical Disk (MO)

Question 27

Is a direct access storage media (a size of a chewing gum stick)
that can hold data from 4Mb (older version) up to 32GB (latest release, future
concept)

Answer 27

Memorystick
