  • ​It is a system of Notation for writing a computer program.
  • First GL is also called Machine Language.
  • The second GL is called assembly Language.
  • Third GL is called a High-level programming language.
  • Fourth GL aims for a higher level of abstraction of internal computer hardware details.
  • Fifth GLare is based on problem-solving.

Key Points

• Memory capacity in computers is typically measured in Bytes.
• A Byte is a unit of digital information that consists of 8 bits.
• Memory sizes are often expressed in multiples of bytes, such as kilobytes (KB), megabytes (MB), gigabytes (GB), and terabytes (TB).
• Each of these units represents a power of 2:
  • 1 KB = 1024 Bytes
  • 1 MB = 1024 KB
  • 1 GB = 1024 MB
  • 1 TB = 1024 GB
• The usage of bytes allows for precise measurement and calculation of digital storage and memory.
• Examples of memory capacity include RAM (Random Access Memory) and storage devices like hard drives and SSDs.

 Additional Information

• Chips
  • Chips refer to integrated circuits used in computers and other electronic devices.
  • They are not a unit of measurement for memory capacity but are critical components in the construction of memory modules.
• KBPS
  • KBPS stands for Kilobits per second.
  • It is a measure of data transfer speed, not memory capacity.
  • Commonly used in network and internet speed measurements.
• Hertz
  • Hertz (Hz) is a unit of frequency, measuring cycles per second.
  • It is often used to describe the clock speed of a CPU, not memory capacity.

The correct answer is Byte.

Key Points

• A group of 8 bits, is called a "byte"
• Binary strings of bits are identified in a number of ways.
• Long strings of bits are called words.
• Modern-day digital computers use 16-, 32-, and 64-bit words.
• A 1 MB (1 megabyte) memory has a storage capacity of one million locations with a byte (8 bits) at each location.

Additional Information1024 bytes = 1 KB
1024 KB = 1 MB
1024 MB = 1 GB
1024 GB = 1 TB
1024 TB  = 1 PB

The correct answer is Register.

Key Points

• Registers are a type of computer memory used to quickly accept, store, and transfer data and instructions that are being used immediately by the CPU.
• It Provides internal storage to the CPU.
• The registers used by the CPU are often termed as Processor registers
• A processor register may hold an instruction, a storage address, or any data.
• The computer needs processor registers for manipulating data and a register for holding a memory address.

Additional Information

• The Memory unit has a capacity of 4096 words, and each word contains 16 bits.
• The Data Register (DR) contains 16 bits that hold the operand read from the memory location.
• The Memory Address Register (MAR) contains 12 bits that hold the address for the memory location.
• The Program Counter (PC) also contains 12 bits which hold the address of the next instruction to be read from memory
• The Accumulator (AC) register is a general-purpose processing register.
• The instruction read from memory is placed in the Instruction register (IR).
• The Output Registers (OR) hold the output after processing the input data.

The Correct answer is Ctrl + K.

Key Points

The Correct answer is Router.

Key Points

• Router.
  • A router is an electronic device that interconnects two or more networks, and selectively interchanges packets of data between them.
  • Routers perform traffic-directing functions on the Internet. Data sent through the internet, such as a web page or email, is in the form of data packets.
  • A packet is typically forwarded from one router to another router through the networks that constitute an internetwork until it reaches its destination node.
  • A router is connected to two or more data lines from different IP networks.

Additional Information

• Switches
  • ​A network switch forwards data packets between devices.
  • Switches are networking devices operating at layer 2 or a data link layer of the OSI model.
  • Switches can be hardware devices that manage physical networks or software-based virtual devices.
• Hub
  • ​A network hub is a node that broadcasts data to every computer or Ethernet-based device connected to it.
  •  A hub has many ports in it. They are generally used to connect computers in a LAN.
• Gateway:
  • A gateway is a crucial network node in telecommunications that serves as a bridge between two networks with different transmission protocols. 
  • Gateways are used to connect and facilitate communication between two networks that use different transmission protocols or technologies. 
• Nibble:
  • In computing, a nibble is a four-bit aggregation or half an octet.
  • It is also known as a half-byte or tetrade.
  • In a networking or telecommunication context, the nibble is often called a semi-octet, quadbit, or quartet.
  • A nibble has sixteen (24) possible values.
  • A nibble can be represented by a single hexadecimal digit (0–F) and called a hex digit.
• ​Cable:
  • ​Network cabling is the process of connecting devices to an Internet source.
  • Network cables can be divided into four types: coaxial, shielded twisted pair (STP), unshielded twisted pair (UTP), or fibre optic.

The correct answer is "a and d".

  • It can be implemented in software and hardware products.
  • It is an output device.

The Correct answer is Procedural Language.

Key Points

• A procedural language
  • It uses a sequence of statements to attain a goal.
  • These steps are called procedures, and a program in such languages contains one or more of these procedures. Common examples include:
    • C and C++
    • Java
    • Pascal
    • BASIC

Additional Information

• A programming language is a formalized set of instructions that enables a programmer to communicate with a computer and provide it with specific tasks and operations to perform. 

Other Types of PRogramming Languages:

• Functional programming language:
  • ​Functional programming languages prioritize mathematical function outputs over statement execution.
  • Functions, as reusable code modules, complete tasks and yield results based on input data. Prominent functional languages are:
    • Scala
    • Erlang
    • Haskell
    • Elixir
    • F#
• Object-oriented programming languages:
  • ​Object-oriented programming languages treat programs as object collections with data (attributes) and operations (methods).
  • Objects can be reused within or across programs, making them ideal for complex tasks with reusable, scalable code. Notable object-oriented languages:
    • Java
    • PHP
    • C++
    • Ruby
    • Python
• Scripting languages:
  • ​Scripting languages automate tasks, handle dynamic web content, and aid processes in bigger apps.

    • PHP
    • Ruby
    • Python
    • bash
    • Perl
    • Node.js
• Logic programming languages:
  • Logic programming languages convey decisions by presenting facts and rules, as opposed to direct instructions. Examples:
    • Prolog
    • Absys
    • Datalog
    • Alma-0

The correct answer is RAM.

Key Points

•  Volatile Memory (RAM): 
  • Unlike ROM, we can read from or write into the RAM, so it is often called read/write memory.
  • The numerical and character data that are to be processed by the computer change frequently.
  • This data must be stored in a type of memory from which they can be read by the processor, modified through processing, and written back for storage.
  • For this reason, they are stored in RAM instead of ROM. RAM is a volatile memory.
  • That is, it cannot hold data when power is turned off.
  • RAM is used to hold programs and data while they are in use.

Additional Information

•  Nonvolatile Memory (ROM):
  • We cannot write data in this memory.
  • ROM is used to store the binary codes for the sequence of instructions you want the computer to carry out and data such as look-up tables.
  • This is because this type of information does not change.
  • There are four types of ROM, Masked ROM, PROM, EPROM, and EEPROM or E²PROM.
• Flash Memory:
  • It is a special type of nonvolatile memory that is often used by portable digital devices for storage.
  • For example, digital cameras, portable MP3 players, USB "keychain" storage devices, and game consoles use flash memory.
  • The flash memory contains millions of tiny switches to store data which is in the form of binary values.
