Explanation:
Personal digital assistant (PDA) is a term for any small mobile hand-held device that provides
computing and information storage and retrieval capabilities for business or personal use such as
keeping schedule calendars and address book information. Most PDAs have a small keyboard. Some
PDAs have an electronically sensitive pad that accepts handwriting.
Answer option D is incorrect. SocketShield provides a protection shield to a computer system against
malware, viruses, spyware, and various types of keyloggers. SocketShield provides protection at the
following two levels:
1.Blocking: In this level, SocketShield uses a list of IP addresses that are known as purveyor of
exploits. All http requests for any page in these domains are simply blocked.
2.Shielding: In this level, SocketShield blocks all the current and past IP addresses that are the cause
of unauthorized access. Answer option A is incorrect. A solid-state drive (SSD) is a data storage
device that uses solid-state memory to store persistent data. An SSD emulates a hard disk drive
interface, thus easily replacing it in most applications. It is also known as solid-state hard disk drive.
SSDs have no
moving parts; hence, they are less fragile and silent than hard disks. As there are no mechanical
delays, SSDs usually enjoy low access time and latency. An SSD using SRAM or DRAM (instead of
flash memory) is often called a RAM-drive, which should not be confused with a RAM disk.
Answer option C is incorrect. A USB flash drive consists of flash memory data storage device
integrated with a USB (Universal Serial Bus) 1.1 or 2.0 interface.
