Answer :
- 1 GB is equal to:
The correct answer is (C) 2^{30} B.
In computing, when using binary (base-2), 1 Gigabyte (GB) is typically defined as 2^{30} bytes. This is because in computing, storage is often calculated in powers of 2.
- 3 bytes is equal to:
The correct answer is (C) 24 bits.
Each byte consists of 8 bits. Therefore, 3 bytes equal 3 × 8 = 24 bits.
- TB stands for:
The correct answer is (A) Terabyte.
TB is short for Terabyte, which is a unit of digital information storage, equal to approximately one trillion bytes (or precisely, 2^{40} bytes in binary terms).
- FTP stands for:
The correct answer is (A) File Transfer Protocol.
FTP is a standard network protocol used to transfer files from one host to another over a TCP-based network, such as the Internet.
- How many types of network standard are there?
While there are numerous network standards depending on the context and specific networking technology, two commonly referenced categories are: wired (Ethernet) and wireless (Wi-Fi) standards, which often leads to answer (B) 4 if considering common options like LAN, WAN, PAN, and MAN.
- The transmission that allows data to move only in one direction at a time is called:
The correct answer is (B) Simplex.
In a simplex transmission, data is sent in only one direction and cannot be sent back.
- The hardware component that permanently holds data and programs is called:
The correct answer is (B) Secondary storage.
Secondary storage is non-volatile and can hold data long-term, such as hard drives and SSDs.
- CPU is also called:
The correct answer is (C) Processor.
The CPU, or Central Processing Unit, acts as the brain of the computer and is also commonly referred to as the processor.
- Which media can be used for backup?
The correct answer is (D) Hard disk.
Hard disks can be used to store backup data due to their large storage capacity and reliability.
- Which bus allows the processor to communicate with peripheral devices?
The correct answer is (B) Expansion bus.
The expansion bus allows additional peripheral devices, such as sound cards and graphics cards, to be added to the computer.
- The output of computer is:
The correct answer is (D) Object code.
Object code is the output code that results when a compiler translates source code for execution on a computer's processor.
- Trojan horse is a/an:
The correct answer is (B) Virus.
A Trojan horse is a type of malicious software (virus) that misleads users of its true intent.
- All of the following are functions of operating system except:
The correct answer is (D) Conversion of source code into object code.
The conversion of source code into object code is the function of a compiler, not an operating system.
- The ability of an operating system to control the activities of multiple programs at the same time is called:
The correct answer is (A) Multitasking.
Multitasking allows multiple processes to share the computational resources of the CPU.
- When creating MS-Word document, the default name of document is:
The correct answer is (C) Document.
In Microsoft Word, the default name for a new document is often "Document1," "Document2," and so on.
