Term. In-memory DBs are often used as a cache for disk databases. True False: Multiprogramming involves the “simultaneous” operation of many jobs on the computer—the computer shares its resources among the jobs competing for its attention. iii) It can be used as secondary memory. … The system ______ generates regular electronic pulses that set the operating pace of the system unit. True or False? It's slower than primary memory. Each character have a unique representation, so the larger the character set, the larger the memory requirement for each character in the set. Output. The von Neumann architecture is characterized by the fact that instructions and data are logically the same and can both be stored in memory. When USE_TZ is False, Django will use naive datetimes in local time, except when parsing ISO 8601 formatted strings, where timezone information will always be retained if present. The program counter points to locations in RAM. TRUE or FALSE. TRUE or FALSE? 6.2. Volatile memory, in contrast to non-volatile memory, is computer memory that requires power to maintain the stored information; it retains its contents while powered on but when the power is interrupted, the stored data is quickly lost. This is an example of an WHAT? True or false. These false memories result from persistent beliefs, post-event information, wrongly stated and interpreted statements, and interference of new memories with old memories. Tags: Question 10 . A microprocessor is a special-purpose computer that is used to control. True or False? Memory is prone to distortions that can have serious consequences in everyday life.

Anurag is a super computer produced by India. getExternalStorageState() method is used to determine the state of the storage media i.e SD card is mounted, is it readable , it is writable etc.. all this kind of information. A megabyte of memory space is larger than a gigabyte of memory space. ____T 2. True. signature. Static RAM is a faster and more dense memory than DRAM Ans-:. Primary memory is usually referred to as RAM True 13. (You may not simply use the word ‘NOT’ to change the statement.) Topics / Hardware / Input Devices. If we use the flash drives instead of the harddisks, then the secondary storage can go above primary memory in the hierarchy. True. True or False: (80 points) 1. parameter. Blood pressure and memory loss are related. The three primitive data types used in this course are int (integer numbers), double (decimal numbers), and boolean (true or false). FTT was initially proposed in the 1990s as an attempt to unify findings from the Select one: O a. You may not simply use the word ‘NOT’ to change the statement.
