What type of device is a disc?
CD, DVD and Blu-Ray Discs CD, DVD and Blu-Ray drives are optical storage devices. Binary data is stored as changes to the texture of the disc’s surface, sometimes thought of as microscopic pits and bumps.
What is disk forensic?
Disk forensics is the science of extracting forensic information from digital storage media like Hard disk, USB devices, Firewire devices, CD, DVD, Flash drives, Floppy disks etc.. The process of Disk Forensics are. Identify digital evidence. Seize & Acquire the evidence. Authenticate the evidence.
Which 2 types of computer data are used as evidence?
Computer documents, emails, text and instant messages, transactions, images and Internet histories are examples of information that can be gathered from electronic devices and used very effectively as evidence.
What is magnetic device in computer?
A magnetic disk is a storage device that uses a magnetization process to write, rewrite and access data. It is covered with a magnetic coating and stores data in the form of tracks, spots and sectors. Hard disks, zip disks and floppy disks are common examples of magnetic disks.
Is a disc an input device?
A hard disk is a storage device that forms one of the four parts of a computer system. Every modern computer has at least one hard disk. A hard disk sends and receives information from the central processing unit (CPU) but is not an input or output device.
What is a forensic boot CD?
The bootable CD/DVDs are used by forensic examiners to boot into a trusted operating system on the suspect’s computer system. This has numerous advantages in some scenarios: 1. Conducting a quick examination of the suspect’s machine at the scene in a trusted operating system.
What is computer evidence?
Computer evidence consists of files and their contents that are left behind after an incident. The existence of some files, such as pictures or executable files, can provide evidence of an incident. In other cases, the contents of files, such as log files, provide the necessary proof.
What are the types of digital evidences?
Digital evidence types This includes email, text messages, instant messages, files and documents extracted from hard drives, electronic financial transactions, audio files, and video files.
What is forensic data collection?
Forensic data collection is the process of defensible collecting or imaging information from a device or cloud-based source for the use of forensic analysis, investigation, or review.
Is a disk an output device?
According to the input signal from input devices the required data i.e. the output signal is send to the output devices. so hard disk is neither input and nor output device.
Is a disk drive an output device?
magnetic data storage devices – These devices may be considered both input and output devices and are labeled I/O devices (for input/output). They include: disk drives (for 3½” floppy disks which are obsolete) hard drives (usually inside the case and not visible) also called the C: drive on a PC.
What is digital forensics Mcq?
The application of computer science and investigative procedures for a legal purpose involving the analysis of digital evidence after proper search authority, a chain of custody, validation with mathematics, use of validated tools, repeatability, reporting, and possible expert presentation.

What is cyber security and computer forensics?
Computer forensics focuses on uncovering and preserving encrypted or lost data, while cyber security is about preventing data loss or cybercrimes from occurring. In short, one is reactionary while the other is preventative.
What is magnetic storage device?
Definition – In the Magnetic storage devices, all data are stored with using magnetized medium, and those types of data saved in that medium in the binary form like as 0 and 1. This magnetic storage has also non-volatile storage nature.
What are the different types of magnetic data storage?
Several types of magnetized media are used in computer systems, including magnetic tape, floppy disks and hard disk drives. The basic approach to magnetic data storage, however, is very similar for the different types of media. A read-write head moves very close to the magnetic surface – the distance is often no more than tens of nanometers.
What are the different types of magnetized media?
Several types of magnetized media are used in computer systems, including magnetic tape, floppy disks and hard disk drives. The basic approach to magnetic data storage, however, is very similar for the different types of media.
What are some examples of magnetic recording devices?
Other magnetic recording devices. Such magnetic recording mediums as drums and ferrite cores have been used for data storage since the early 1950s. A more recent development is the magnetic bubble memory devised in the late 1970s at Bell Telephone Laboratories.
