What is true of a secondary immune response? It is brought about by memory cells It is weaker than a primary immune response. It can involve B-cells but not T-cells It is faster than a primary immune response After it occurs, the immune system can only respond to reinfection with the same antigen by mounting another primary immune response 1 and 2 2, 4, and 5 1, 3, 4, and 5 1, 2, and 3 1 and 4

Project 2: Database System Design
Background:
An department store is currently developing a new database
system to store all of its information. The new system would enable
the store to enter data regarding inventory levels, ordering, and
so on.
Currently, the data for inventory and sales tracking are
stored in one file that has the following format:
Item List: ItemID, ItemName, Item Description, Price,
Cost,
Supplier List: SupplierID, SupplierName,
Supply order List: SupplyOrderID, ShippingTime,
DeliveryDate,
Inventory List: InventoryID, QuantityOnHand,
Customer...

For the efficient memory management and to avoid errors modern systems uses secondary memory as a part of the main memory known as a virtual memory. When a computer system is running serval programs at the same time, the main memory often becomes exhausted. In such circumstances instead of closing some programs the operating system use the secondary memory as part of the main memory to store some data. In short virtual memory is an elegant interaction of hardware exceptions,...

In most multiprogrammed systems, user programs access memory through virtual addresses, while the operating system uses raw physical addresses to access memory. What are the implications of this design on the initiation of I/O operations by the user program and their execution by the operating system?
