Step 1
(i) CPU
Answer
The term CPU stands for Central Processing Unit. It is the primary component of a computer that performs most of the processing inside the system. The CPU carries out instructions from programs by performing basic arithmetic, logic, control, and input/output (I/O) operations specified by the instructions. It is often referred to as the 'brain' of the computer.
Step 2
(ii) LAN
Answer
LAN stands for Local Area Network. It refers to a network that connects computers and devices within a limited geographical area, such as a home, school, or office building. A LAN is typically used to share resources like files, printers, and internet connections. LANs are characterized by higher data-transfer rates and lower latency than wide area networks (WANs).
