Which standard governs parallel communications?
- A.
RS232
- B.
RS-232a
- C.
IEEE 1284
- D.
None
Correct Answer
C. IEEE 1284Explanation
IEEE 1284 is the correct answer because it is the standard that governs parallel communications. RS232 and RS-232a are incorrect options as they are standards for serial communications, not parallel communications. The option "None" is also incorrect as there is a standard that governs parallel communications, which is IEEE 1284.Rate this question:

Which of the following file format supports Win 7?
- A.
NTFS
- B.
BSD
- C.
Ext
- D.
All of them
Correct Answer
A. NTFSExplanation
NTFS (New Technology File System) is the correct answer because it is the default file system used by Windows operating systems, including Windows 7. NTFS offers features such as improved security, file compression, and support for larger file sizes and volumes. BSD and ext are file systems used by Unix-like operating systems and are not natively supported by Windows. Therefore, the correct file format that supports Windows 7 is NTFS.Rate this question:

The term gigabyte refers to?
- A.
1024 bytes
- B.
1024 kilobytes
- C.
1024 megabytes
- D.
1024 bits
Correct Answer
C. 1024 megabytesExplanation
A gigabyte refers to 1024 megabytes. In the binary system, each level is a multiple of 2, so a kilobyte is 1024 bytes, a megabyte is 1024 kilobytes, and a gigabyte is 1024 megabytes. This is commonly used in computer systems to measure data storage capacity.Rate this question:

The storage capacity of a disk system depends on the bits per inch of the track and the tracks per inch?
- A.
Cylinder
- B.
Hum
- C.
Cluster
- D.
Surface
Correct Answer
D. SurfaceExplanation
The correct answer is "Surface" because the storage capacity of a disk system is determined by the number of tracks per inch and the bits per inch of each track. The surface refers to the physical surface of the disk where the tracks are located. Increasing the number of tracks per inch and the bits per inch on each track allows for more data to be stored on the disk's surface, thus increasing the storage capacity.Rate this question:

Virtual memory in windows can be changed from?
- A.
Hiberfile.sys
- B.
Pagefile.sys
- C.
All the above
- D.
None
Correct Answer
B. Pagefile.sysExplanation
Virtual memory in Windows can be changed from the "Pagefile.sys" file. The Pagefile.sys file is a hidden system file on the hard drive that Windows uses to store data when the system's physical memory (RAM) is full. It acts as a supplement to the RAM, allowing the operating system to allocate more memory to running applications. By adjusting the settings of the Pagefile.sys file, users can modify the amount of virtual memory allocated by the system, thereby optimizing performance based on their specific needs.Rate this question:

- D.
7
Correct Answer
D. 7Explanation
The OSI layer model is a conceptual framework that standardizes the functions of a communication system into seven different layers. These layers are responsible for different tasks such as data transmission, error detection, and network management. Each layer builds upon the one below it, creating a hierarchical structure. Therefore, the correct answer is 7.Rate this question:

IPv4 address is of ------- bits.
- A.
4
- B.
8
- C.
16
- D.
32
Correct Answer
D. 32Explanation
An IPv4 address is made up of 32 bits. This means that it consists of a sequence of 32 binary digits, which are used to identify and locate devices on a network. IPv4 addresses are typically expressed in decimal format, with each 8 bits represented by a number ranging from 0 to 255. The 32-bit structure of IPv4 addresses allows for a total of approximately 4.3 billion unique addresses, which are used to assign unique identifiers to devices connected to the internet.Rate this question:

Which is the core of the operating system?
- A.
Shell
- B.
Kernel
- C.
Commands
- D.
Script
Correct Answer
B. KernelExplanation
The kernel is the core component of an operating system. It is responsible for managing the system's resources, such as memory, processes, and hardware devices. The kernel acts as a bridge between the hardware and software, allowing applications to communicate with the hardware. It provides essential services and functions that enable the operating system to function properly. Without the kernel, the operating system cannot perform its tasks effectively, making it the core of the operating system.Rate this question:
-

Applications communicate with kernel by using:
- A.
System Calls
- B.
C Programs
- C.
Shell Script
- D.
Shell
Correct Answer
A. System CallsExplanation
Applications communicate with the kernel by using system calls. System calls are functions provided by the operating system that allow applications to request services from the kernel. These services can include tasks such as file operations, network communication, process management, and memory allocation. By making system calls, applications can access the underlying functionality of the operating system and perform tasks that are not directly available to them.Rate this question:

Which directory contain device special files?
- A.
/etc
- B.
/etc/dev
- C.
/root/bin
- D.
/dev
Correct Answer
D. /devExplanation
The correct answer is /dev. The /dev directory contains device special files, which are used to interact with hardware devices on the system. These files represent devices such as hard drives, printers, and network interfaces, and allow users and applications to read from and write to these devices as if they were regular files. By accessing the device special files in the /dev directory, the operating system can manage and control the various hardware devices connected to the system.Rate this question:

Which among the following allows fast file system recovery?
- A.
Ext2
- B.
Journaling
- C.
Caching
- D.
Sysfs
Correct Answer
B. JournalingExplanation
Journaling allows fast file system recovery by keeping a log of changes before they are actually made to the file system. This log, or journal, records all the modifications that need to be made to the file system metadata. In the event of a system crash or power failure, the file system can quickly recover by replaying the journal and applying the recorded changes. This ensures that the file system remains consistent and reduces the need for time-consuming file system checks.Rate this question:
-
- 25.
Which file system has journaling capability?
- A.
Ext2
- B.
Ext4
- C.
Isofs
- D.
Procfs
Correct Answer
B. Ext4Explanation
Ext4 is the correct answer because it is a file system that has journaling capability. Journaling is a feature that helps to ensure the integrity of the file system by keeping track of changes before they are actually committed to the disk. This allows for faster recovery in case of system crashes or power failures, as the file system can use the journal to quickly restore any incomplete transactions. Ext2, Isofs, and Procfs do not have journaling capability, making Ext4 the only suitable option.Rate this question:
