Question 1
A large heating and air conditioning company provides each employee with a small
computing device that the employees use to track work and accept payments. Which
term refers specifically to this type of device?
A) Peripheral computer
B) Microcomputer
C) Minicomputer
D) Handheld computer
Correct Answer: D) Handheld computer
Rationale: A handheld computer (also known as a personal digital assistant or mobile
device) is a small, portable computing device designed for specific tasks such as
tracking work and processing payments. Peripheral computers are auxiliary devices
connected to a main computer. Microcomputers include desktops and laptops, while
minicomputers are mid-sized systems typically used by multiple users simultaneously.
Question 2
What is the major function of a computer operating system?
A) Data management
B) Application program management
C) Network management
D) Computer resource management
,Correct Answer: D) Computer resource management
Rationale: The operating system's primary function is managing computer resources
including memory, processing power, storage, and input/output devices. While it does
manage applications and data, these are subsets of its broader resource management
role. Network management is typically handled by additional software components.
Question 3
Within a productivity suite, which method of selecting static data from one application
and copying it to another application requires the use of temporary memory?
A) File transfer
B) Object embedding
C) Object linking
D) Copy and paste
Correct Answer: D) Copy and paste
Rationale: Copy and paste uses the clipboard, a temporary memory area, to store data
temporarily during the transfer between applications. File transfer moves entire files,
while object embedding and linking maintain connections between source and
destination files without using temporary memory in the same way.
Question 4
What are the basic components, in addition to computers, that are required for a local
network to function?
A) Ethernet cards, a common protocol, ethernet cables, and a hub
B) Ethernet cards, a modem, a router, and a network database
C) Internet connection, a network interface controller, and a cabling system
D) Internet connection, a network operating system, and a network administrator
, Correct Answer: A) Ethernet cards, a common protocol, ethernet cables, and a hub
Rationale: A local area network (LAN) requires network interface cards (Ethernet cards)
for each device, a common communication protocol (like TCP/IP), physical cabling
(Ethernet cables), and a central connecting device (hub or switch). An internet
connection is not required for a LAN, and network administrators are personnel, not
hardware components.
Question 5
Which type of device is an ethernet card?
A) Network interface controller (NIC)
B) Network firewall hardware
C) Network operating system (NOS)
D) Network server hardware
Correct Answer: A) Network interface controller (NIC)
Rationale: An Ethernet card is a specific type of Network Interface Controller (NIC) that
allows a computer to connect to a network using Ethernet protocols. Firewalls, network
operating systems, and server hardware are distinct components that serve different
functions in network architecture.
Question 6
What is the purpose of a MAC address?
A) To uniquely identify an internet URL
B) To uniquely identify a computer motherboard
C) To uniquely identify an email client
D) To uniquely identify a computer on a network
