Which address is more important the physical address or the logical address?
In the 8086/8088 the physical address and logical address have the same importance, because they both relate to the address of the operand. It is true that the offset (logical) address is added to the segment address to determine the physical address, but the limitations of the architecture of the processor forces programmers to consider both.If you are talking about a virtual environment, however, such as in the 80286 or higher, then the logical address is more important than the physical address, because the logical address is the address of the operand, while the physical address is (somewhat) arbitrarily assigned by the operating system.
What is LDA in subject of computer system architecture?
LDA in terms of computer system architecture stands for Logical Device Address. A LDA is a one byte address (i.e an upper MAC address) and there is no physical address (i.e lower MAC address) specified.
Differentiate physical and logical addresses?
logical address and physical addressIn a system, there are two types of addresses: logical and physical. Another name for logical address is IP address and it is set by your Internet service provider (ISP) or your router. If you have a router then you have a LAN, which sets a logical address for your computer. Your router will have an logical address set by your ISP.The physical address is also called the MAC address and it is generated by the manufacturer. (but only to a given extent)Because a MAC address is assigned (by the FCC) to a company to use for a range of products.For example:01:23:45:00:00:00 - 01:23:45:FF:FF:FFWould be their "range" of MAC addresses. They use a coding called Hex which is not to far off from what you know which is base-10 (0-9).Instead hex uses (0-F). 0123456789ABCDEFA = 10, B = 11, etc.Read more: What_is_the_difference_between_logical_address_and_physical_addresses
What is logical address in computer networks?
logical address is called as global address and physical address is called as local address .the ip address,which is used by the user in the network is found to be global for use and it is easily identified in any network .physical address is mac address ,which is stored in the nic card,which is mainly used ,when the system is connected in the network using switch
What are logical and physical address?
Through logical address the system identify a network (source to destination). after identifying the network physical address is used to identify the host on that network. The port address is used to identify the particular application running on the destination machine.Logical Address: An IP address of the system is called logical address. This address is the combnation of Net ID and Host ID. This address is used by network layer to identify a particular network (source to destination) among the networks. This address can be changed by changing the host position on the network. So it is called logical address.Physical address: Each system having a NIC(Network Interface Card) through which two systems physically connected with each other with cables. The address of the NIC is called Physical address or mac address. This is specified by the manficture company of the card. This address is used by data link layer.Port Address: There are many application running on the computer. Each application run with a port no.(logically) on the computer. This port no. for application is decided by the Karnal of the OS. This port no. is called port address.
How logical architecture of DBMS differs from physical architecture?
Architecture is the frame work of the Database Management System. They are simply classified into logical and physical.
What is the use of resident monitor in memory management?
1. It is a Primitive Operating System. 2. Usually in low memory where interrupt vectors are placed. 3. It Isolate user from physical address space using logical address space
What is the IP address of smart?
IP address is a logical address of a system which could be used to identify it. There are 2 types of IP address, IPV6 and IPV4.
Consider a computer system with a 32 bit logical address and 4-KB page size The system supports up to 512 MB of physical memory?
4kb = 2^12 2^32 / 2^12 = 2^20
What is mean logical virus?
A logical virus is a type of malware that infects a computer system by manipulating the logical operations of the computer rather than its physical components. These viruses spread through computer networks and can cause damage by corrupting data or disrupting normal system functions. They are designed to exploit vulnerabilities in the software or operating system to gain control over the infected system.
