Unit 1 Explain And Define The Following Components

Although DRAMs become less reliable when they are not refreshed, they are not immediately erased, and their contents persist sufficiently for malicious (or forensic) acquisition of usable full-system memory images

RAM: RAM stands for Random Access Memory. It is a bit like a person's short-term memory. RAM is volatile so data only exists only when the computer is turned on, and is used by the operating system and other applications.

RAM (Random Accesses Memory): RAM is used by CPU when a computer is running to store the information that it needs to be used very quickly but it does not store any information permanently.

Your hard drives are what store all of your data, ranging from your operating system to your documents, music, and movies. If the RAM is your computer's short-term memory, your hard drive is the long-term memory. It stores the things you want to keep around for a while.

Irregular Access memory is inside the PC which store the information and work with capacity memory to make lessen less and influence space for essential things to like record and documents in light of the fact that for individual protection.

Random Access Memory (RAM) - the storage of data and instructions inside the primary storage is temporary. It disappears from the RAM as soon as the power to the computer is

c) The memory chip reply with the data from the demanded memory position on the data bus.

List and describe at least three types of storage that is typically included in all computer systems.

a File or space on the hard drive where data from RAM is "swapped" in order to preserve space.

Flash memory is a solid-state drive (SSD) that maintains data storage without moving parts, even

There are three types of storage devices. Magnetic storage devices store data as magnetic dots on spinning disks. These dots are written and read by an electromagnet. Examples of magnetic storage devices include Hard Drives (HDD) and Floppy Disks. Optical storage devices store data as coloured dots or small indentations on spinning disks. This data

Linux uses the virtual memory to free up private or anonymous pages used by a process. When a page is ‘taken off’ the physical memory, it is copied to the backing store, also sometimes named swap area. Linux uses the term ‘swapping’, which usually refers to swapping a whole process out from another, to describe ‘paging’, which is the swapping of the inactive pages of a process or processes.

Random-access memory (RAM)- A type of short-term memory computer memory used by computers, primarily used as a temporary working memory by the CPU.

Firstly standardization ensure compatibility between products and their complements (other products used with them). Example- PCs with software. The economic benefits here is reducing the products

Technology continues to evolve exponentially. However these technological advancements continue to pose a threat to both individuals and information resources of companies and governments. There is therefore the need to protect one’s data and information due to the emerging threats and risks. Hacking is where third parties create a backdoor version of a hardware and software so as to manipulate or unlock hidden functionalities on a machine. Most of these hacks are open source and free soft wares. These hacks manipulate the firmware update option on many devices to run and install themselves. Many researchers have found out that breaking into
